Control Break out of Infinite Loop In 2010 (2013) Excel VBA - excel

If I write code creating an infinite loop, with my new Excel, the Ctrl + Break no longer works. Neither does the Esc key, etc.
I've looked all over the web and it appears that Microsoft has a bug and doesn't care to fix it.
Is there a way to re-introduce the Ctrl + Break function to VBA so if this happens in the future I don't lose work / force close?

Alt + Esc. Hold down the keys until it breaks.
From Windows 7 on, this will cycle through all open windows. Pay no mind, just keep squeezing it.

On Office 2013, at least, Ctrl+Scroll Lock does it. I didn't need to change any settings or enable anything.
(Blatant plug: my blog post linking to the original source of this info :) )

One way to mitigate this very annoying behaviour is to include
DoEvents
In the loop. It doesn't have to be executed every iteration, so long as it is called periodically, Ctrl Break will still work.
Note: I usually remove this after the code is debugged, to avoid any performance impact

For those who tried the previously proposed solutions to no avail, try this. It worked for me (windows8, Excel 2016)
On the VBA code window, left-click and hold (as though you are going to drag that window) while holding down the Alt+ESC keys. It broke the execution and asked me if I wanted to continue, or debug... I of course chose debug.

If it can help anyone, pressing Ctrl+break when the macro is not running only works if you do it outside of the developer.

An alternative will be introduce error intentionally in the loop. Say for e.g. your loop should not be running more than 1000 times:
Function XYZ()
do while(..)
errcnt = errcnt + 1
if errcnt > 1000 then
cells.find(what:="Chunk Norris").activate
exit function
endif
loop
end function
it will produce an error and 'break' the code

Break (Ctrl + Break) is also not available in the VBA editor if you are in design mode. In that case you can press the Design Mode icon which is to the right of the square stop icon. This brings the editor back in regular mode and the break option then becomes available.

There is no "Break" button on my poor keyboard. My only alternative is to hit the X to close the program or alt+F4. I'll have to code something as well.

From answers.microsoft.com, simply press ESC a few seconds when the focus is on your Excel window. At least, it works for me on Excel 2016.

MS. VBA Debugging "Run to Cursor" not working

Hello all,
this has me quite baffled as I dont even know how to even search for a solution to this.
Basically the problem is that when I'm debugging, after I stop the code in a breakpoint, the debugger can only go line by line and seems to not be able to "Run" (with F5, just continuing executing the code) or "Run to Cursor" to execute the code until the position the cursor is.
This makes of course very difficult the debugging, especially in cases where you just want to skip over a for-loop with 300000 iterations and not go through it one by one...
I have somehow found a workaround, although not really: I can set a breakpoint at some point down the code and select "Step Out" (Ctrl+Shift+F8) and the program will execute until the next breakpoint. This is far from ideal as I need to be setting and removing the breakpoints instead of just placing the cursor where I wanted the program to go and click Ctrl+F8. This operation is something I probably do hundreds of times while I am debugging and now I just go so much slower.
I wondered if any of you encountered this problem and know how to fix it or change this behaviour?
I should mention that the issue came when I changed my computer for a new one. I'm using Microsoft Visual Basic for Applications 7.1 within MS Excel in Microsoft Office 365

Can't enter break mode at this time

This has been happening increasingly, when I have a sheets.add or sheets.delete in excel VBA. After searching and searching I finally found the official Microsoft support page on it. My question is, does anyone know why I could have stepped through this code just fine over and over, and then all of a sudden it starts doing what Microsoft says it would always do, and is there a way to fix it?
Sub foo()
Sheets.add
debug.print "sheet added" 'breakpoint here
End sub
It's as simple as that. You won't be able to recreate it, because the issue I'm asking about is the fact that it doesn't happen at first. It works just fine over and over then randomly presents the error described in the linked Microsoft support page.
Check if Microsoft Visual Basic for Applications Extensibility is being referenced in the project.
You can check that in the Tools/References Menu on the Visual Basic window of the project.
Referencing Visual Basic for Applications Extensibility prevents the program having its execution suspended:
Excel helps says specifically:
A change was made programmatically to the project using the extensibility (add-in) object model. This prevents the program from having execution suspended. You can continue running, or end execution, but can't suspend execution.
You are unable to step through code when making changes to the project (dynamically eg using InsertLine etc). the code can be run but not stepped through.
Deleting certain objects including ActiveX objects actually changes the VB project. It took me some time to realize that the following line of code prevented the VBE from entering break mode:
Excel.ActiveSheet.DrawingObjects.Delete
If you can identify the code causing the issue, and the order of operations isn't important, move it to the end of your script.
Here are a few suggestions which are not fool-proof,
Firstly, verify that the error does not occur if a breakpoint is not set.
If it doesn't, try a few other things:
From the VBE Debug menu, "Compile VBA Project", it's worth a shot.
Delete the line entirely. Run the code. Then put the line back in and try again with the breakpoint.
Add a DoEvents statement after the Sheets.Add
Use a MsgBox instead of a breakpoint on a Debug.Print. With the message box displayed, attempt to manually break using ctrl+fn+End. (At this point, "breaking" isn't necessary but it would be interesting to see whether you can break this way)
Put a breakpoint on Sheets.Add instead; practically speaking, there's no reason to put the breakpoint on a Print statement if you can just put it on the preceding line.
Are there any Addins? If so, disable all of them and re-enable one at a time, testing to see which one may contribute to the error.
Yet another Excel/VBA glitch.
When it happens to me when I click a button running a macro:
I first try to directly run the macro from VBE,
if it fails, then I put a breakpoint at the first instruction of the macro,
if it still fails, I try both,
or, after clicking the button and breaking on the first breakpoint, I do a single step (SHIFT F8) and then I can let debug run freely as usual (F5).
And so far I don't get this error anymore.
Probably not foolproof either but worth a try.
Ran into the same issue, and (as far as I can tell) the only relevant answer here is Answer 5 (i.e. the one provided by Chrisb).
I've been working with vba for (too many) years now, and never encountered this until I had a project that needed vba to delete ActiveX controls. In my case, the 'ActiveX controls' were a spurious result of data copied in from a web page.
Additionally, there appears to be a way around the issue. Using the following code (versus, e.g. deleting the ActiveX as a shape), seems to circumvent the issue:
On Error Resume Next
ActiveSheet.OLEObjects.Visible = True
ActiveSheet.OLEObjects.Delete
On Error GoTo 0
I say 'appears' and 'seems' above as implementing the above solved the issue for me. However, before I implemented same, I had made other code changes and I have not yet fully regression tested for all possible other reasons the problem was resolved. :)
This has happened to me multiple times and this solution works for me.
Run a different macro within the same VBA project.
Then go back and run the same macro that is causing the pop-up message to appear. The message should no longer appear.

How to disable auto backspace in Excel VBA editor

When typing in the editor it puts me back on the end of the last word.
For example, I want Sub Entername()
If I'm not typing quickly enough it goes: SubEnterName().
How do I turn this off.
I've heard of this problem before. Try these steps:
Close down excel.
Open it first it in safe mode (type "excel.exe /s" in the run box).
Open the VBA Editor and attempt to write a macro. The issue should not occur
Close down excel and re open it normally
I've heard these steps have fixed this issue before for others.
Are you using any VBE addins like Smart Indenter or Code Cleaner? Remove Code Cleaner and install it only when you are going to use it, then uninstall it when you are done. I had the same problem and Code Cleaner was the culprit. I believe it might be the two of them together that causes it.
For reference:
VBA Code Cleaner
Smart Indenter
This issue is because of a COM Add-In called 'Load Test Report Addin'. to disable it, do the following:
go to Excel Options -> Add-Ins and choose Excel COM Add-ins from bottom drop down and press Go... button. then uncheck the 'Load Test Report Addin' item to diable it. this will clear the problem!
To prevent auto refreshing and deleting back-spaces in VBA editor, you should make sure that all forms or reports that have On-Timer Event Procedures are in design view or the code should be turned-off (i.e. converted into comments).
However, it is better to make sure that all forms and reports are in design view which means none of the On-Timer codes are executing.
I hope this helps.
Shafiu.
Do you have AutoSave turned on? I had a file doing this just now. While typing, as SOON as I stopped, AutoSave was working away - (inadvertently, I'm sure) this was causing VBE to kill spaces.
Did two tests:
-Moved the file off Sharepoint onto my local machine, worked fine
-Turned off AutoSave on the Sharepoint copy, worked fine

VBA editor auto-deletes spaces at the ends of lines

Is there a way to convince the VBA editor in Excel to stop auto-formatting lines to remove the space at the end when I pause in my typing for a quarter second?
I had this exact problem and the following worked for me.
Click the Microsoft Office Button, and then click Excel Options
Click the Add-Ins category
In the Manage box, click COM Add-ins, and then click Go.
Look for an add in called 'Load Test Report AddIn' then uncheck it
restart excel
This addin is installed with VS2010 Beta2
In Excel 2010, toggling Design Mode button on the Developer Ribbon Tab solves the problem for me.
I've definitely had that issue before, where the vba editor would format as I was typing (not just when I went to another line). For me, it seemed to be related to a Microsoft Web Browser control that I had in an open workbook. When I took out the web browser, the VBA editor started acting normally again. I have no idea why that worked, but it did. Now I avoid using that control in my workbooks.
Something is causing your spreadsheet to recalculate while you are in the VBA Editor and this 'compiles' your code and thus strips the spaces. You need to stop the cells recalculating while you are editing. Turning the calculation to manual in the spreadsheet.
Tools > Options > Calculation should do the trick.
I noticed this when I had cells recalculating thanks to a DDE connection.
There is sort of a way to turn off the auto-"correction" in the VBA Editor.
Tools Menu -> Options -> Editor Tab -> Clear the Auto Syntax Check box
Sadly, this won't solve all your problems, as the VBA Editor tends to have a mind of its own, for better or worse.
Taking it out of design mode fixes it every-time on vba2003 - its was driving me crazy at first ... i did notice it might have something to do with the web control but when i take it out of design mode it works fine ... just toggle that to get it to behave :)
I have had this same problem several times recently, and has driven me crazy.
After reading this post all the different fix-ups mentioned (none worked for me), I recalled I have been playing lately with Internet Explorer Control, opening Internet Explorer from VBA.
This is mentioned in some of the answers in this post.
This got me in the right path and, in order to fix it, I had to first delete all iexplore.exe instances (alt+control+delete), closed Excel and open excel again.
(iexplore.exe had been opened invisible from the VBA code, and I didn't know they were running)
That fixed the bug.
I have been programming quite heavily with VBA for over 4 years, and never had this problem.
Just a couple of weeks ago I started using IE control, and I started getting this problem...so in my case I can only assume the bug is directly related to the IE control.
I am running both excel 2003 and 2007 in same PC at the same time, and the problem only happens with excel 2007.
None of the above for me.
I had a Application.OnTime timer that fired every second and this triggered a recalculation of something: commenting it made my day.
This has started happening to me recently after adding a Timer event to an Access 2007 form. The VB editor "finalizes" the current line (as if you had moved the cursor off of the statement; I have auto syntax checking off) each time the event fires (initially I had it set to 1 second, now it is set to 5 seconds, and the behavior scales accordingly). In order for the event code to execute, the application has to ensure that it has been compiled. Presumably, the editor needs to be in a "sane" state to do this, as it probably has to check for code dependencies among modules. Note that the behavior occurs regardless of whether any dependent code is actually loaded into the editor at the time. Note also that resetting the execution state doesn't affect the timer event firing. As a practical matter, one could close the triggering form, switch it to design view, set a breakpoint in the triggered code, or increase the timer interval while working with the editor.
In contrast to abhishek's comment, changing the settings of Tools/Options.../General/Compile On Demand and/or Background Compile did not affect the issue.
If it helps, none of the previous answers solved mine. Only solution appeared to be to close the xls file and reopen it. Frustrating to have to do every 30 mins but at least it works. Would love to know why it's recompiling and cleaning the text... should really be an option to disable the text cleanup but couldn't find it.
Turn off Tools > Options > General > Background Compile. This solved it for me.
This is a long standing problem that could have various causes. I had this same issue occur in the Access VBE (so naturally the Excel answers weren't relevant). After a LOT of digging I finally got it fixed with the solution below. First a recap though:
If you are here because of this issue in Excel, try the solutions above first. To summarize:
The most common issue in Excel is that the Design button is toggled. Toggle that and see if the behavior changes as submitted by Dmitry Frenkel above
If that doesn't work, check for the "Load Test Report" AddIn as mentioned by Ade.
Those are really the two main causes in Excel, but if neither of those solutions work, then scroll through the rest of the solutions here. All are valid possibilities for the cause. In Access the cause is pretty straight forward. It's a timer issue on a form somewhere. I found this solution from here by User Kevin K. Sullivan.
Copy the following line of code onto the clipboard. (You might need to
paste it into a text editor first and coerce it onto one line, depending on
your newsreader. It must be one line.)
For i = 0 to Forms.Count -1: Debug.Print Forms(i).Name, Forms(i).TimerInterval: Next i
Switch to Access.
Press Ctrl-G to go to the Immediate Window.
Press Ctrl-V to paste in the code.
Press enter to to run the code. All open forms will be listed. Any non-zero timer intervals are your culprits. Simply close that form (It may be invisibly open from another process than the one you thought you were dealing with).
I think the solution for Access here is what the user Dom was trying to say above. I guess the down votes were because it wasn't explained very well and/or because he was speaking of Access when the OG issue was in Excel. Regardless, he is likely on point if you are here because of the VBE in Access.
I hope this helps people. I know I kept finding this page when researching this issue, so that's why I thought I'd update this solution here.
I hit this problem today on a fresh install of Excel 2010 Beta 2. None of the above made any difference, but going into the trust center and disabling all application add-ins fixed the problem for me.
I have Office 2010 Pro and I had the same issue. As I type the space between each word was being deleted. After trying each of the options turning them on and off the only way I found working was to disable the Winzip Courie(excel) add-in. This is done thru the Options dialog box Add-Ins section.
In office 365 I had the same issue - what worked for me is I saved the file with a different name and when I re-opened the new file the problem went away.
I found this issue pops up when I had AutoSave on. Turning that off let me code without it compiling every second.
I don't think I've ever seen the VBE remove a space when I've stopped typing. It will remove trailling spaces from lines if you move to another line, but that's something different and not behaviour that I think can be altered.
The removal of spaces in the VBA editor for Access occurs when a form is open in Form("Execute") mode. This is probably due to background executions based on "On Timer" methods. Close the form in Access solves the problem in VBA.

Excel VBA App stops spontaneously with message "Code execution has been halted"

From what I can see on the web, this is a fairly common complaint, but answers seem to be rarer. The problem is this:
We have a number of Excel VBA apps which work perfectly on a number of users' machines. However on one machine they stop on certain lines of code. It is always the same lines, but those lines seem to have nothing in common with one another.
If you press F5 (run) after the halt, the app continues, so it's almost like a break point has been added. We've tried selecting 'remove all breaks' from the menu and even adding a break and removing it again.
We've had this issue with single apps before and we've 'bodged' it by cutting code out of modules, compiling and then pasting it back in etc.
The problem now seems to relate to Excel itself rather than a single .xls, so we're a little unsure how to manage this.
Any help would be gratefully received :)
Thanks,
Philip Whittington
I have found a 2nd solution.
Press "Debug" button in the popup.
Press Ctrl+Pause|Break twice.
Hit the play button to continue.
Save the file after completion.
One solution is here:
The solution for this problem is to add the line of code
“Application.EnableCancelKey = xlDisabled” in the first line of your
macro.. This will fix the problem and you will be able to execute the macro
successfully without getting the error message “Code execution has been interrupted”.
But, after I inserted this line of code, I was not able to use Ctrl+Break any more. So it works but not greatly.
This problem comes from a strange quirk within Office/Windows.
After developing the same piece of VBA code and running it hundreds of times (literally) over the last couple days I ran into this problem just now. The only thing that has been different is that just prior to experiencing this perplexing problem I accidentally ended the execution of the VBA code with an unorthodox method.
I cleaned out all temp files, rebooted, etc... When I ran the code again after all of this I still got the issue - before I entered the first loop. It makes sense that "press "Debug" button in the popup, then press twice [Ctrl+Break] and after this can continue without stops" because something in the combination of Office/Windows has not released the execution. It is stuck.
The redundant Ctrl+Break action probably resolves the lingering execution.
I found hitting ctrl+break while the macro wasn't running fixed the problem.
I would try the usual remedial things:
- Run Rob Bovey's VBA Code Cleaner on your VBA Code
- remove all addins on the users PC, particularly COM and .NET addins
- Delete all the users .EXD files (MSoft Update incompatibilities)
- Run Excel Detect & Repair on the users system
- check the size of the user's .xlb file (should be 20-30K)
- Reboot then delete all the users Temp files
I have came across this issue few times during the development of one complex Excel VBA app. Sometimes Excel started to break VBA object quite randomly. And the only remedy was to reboot machine. After reboot, Excel usually started to act normally.
Soon I have found out that possible solution to this issue is to hit CTRL+Break once when macro is NOT running. Maybe this can help to you too.
Thanks to everyone for their input. This problem got solved by choosing REPAIR in Control Panel. I guess this explicitly re-registers some of Office's native COM components and does stuff that REINSTALL doesn't. I expect the latter just goes through a checklist and sometimes accepts what's there if it's already installed, maybe. I then had a separate issue with registering my own .NET dll for COM interop on the user's machine (despite this also working on other machines) though I think this was my error rather than Microsoft. Thanks again, I really appreciate it.
I have had this problem also using excel 2007 with a foobar.xlsm (macro enabled ) workbook which would get the "Code execution has been interrupted" by simply trying to close the workbook on the red X in the right corner with no macros running at all, or any "initialize" form, workbook, or workheet macros either. The options I got were "End" or "Continue", Debug was always greyed out. I did as a previous poster suggested Control Panel->Programs and Features-> right click "Microsoft Office Proffesional 2007" (in my case) ->change->repair.
This resolved the problem for me.
I might add this happened soon after a MS update and I also found an addin in Excel called "Team Foundation" from Microsoft which I certainly didnt install voluntarily
I would like to add more details to Stan's answer #2 for below reasons:
I faced this issue myself more than dozen times and depending on project conditions, I chose between stan's voodoo magic answer #1 or #2. When I kept on facing it again, I become more inquistive that why it happens in first place.
I'd like to add answer for Mac users too.
There are limitations with both these possible answers:
if the code is protected (and you don't know password) then answer #1 won't help.
if the code is unprotected then answer #2 won't let you debug the code.
It may happen due to any of the below reasons:
Operating system not allocating system resources to the Excel process. (Solution: One needs to just start the operating system - success rate is very low but has known to work many times)
P-code is the intermediate code that was used in Visual Basic (before .NET) and hence it is still used in the VBA. It enabled a more compact executable at the expense of slower execution. Why I am talking about p-code? Because it gets corrupted sometimes between multiple executions and large files or just due to installation of the software (Excel) went corrupt somewhere. When p-code corrupts. the code execution keeps getting interrupted. Solution: In these cases, it is assumed that your code has started to corrupt and chances in future are that your Excel workbook also get corrupt giving you messages like "excel file corrupted and cannot be opened". Hence, as a quick solution, you can rely on answer #1 or answer #2 as per your requirements. However, never ignore the signs of corruption. It's better to copy your code modules in notepad, delete the modules, save & close the workbook, close the excel. Now, re-open the workbook and start creating new modules with the code copied earlier to notepad.
Mac users, try any of the below option and of them will definitely work depending on your system architecture i.e. OS and Office version
Ctrl + Pause
Ctrl + ScrLk
Esc + Esc (Press twice consecutively)
You will be put into break mode using the above key combinations as the macro suspends execution immediately finishing the current task. This is replacement of Step 2.
Solution: To overcome the limitation of using answer #1 and answer #2, I use xlErrorHandler along with Resume statement in the Error Handler if the error code is 18. Then, the interrupt is sent to the running procedure as an error, trappable by an error handler set up with an On Error GoTo statement. The trappable error code is 18. The current procedure is interrupted, and the user can debug or end the procedure. Microsoft gives caution that do not use this if your error handler has resume statement else your error handler always returns to the same statement. That's exactly we want in unwanted meaningless interruptions of code execution.
My current reputation does not yet allow to post this as a comment.
Stans solution to enter the debug mode, press twice Ctrl+Break, play on, save did solve my problem, but I have two unexpected twists:
My project struture is password protected, so in order to get into the Debug Mode I had to first enter Developer mode, click on the project structure and enter the password.
My project is a template file (.xmtl). I opened the file via double click which opens it as .xml with a "1" at the end of the previous file name. I fixed the bug as by Stans instruction and saved it as that ...1.xml file. When I then opened the template again, this time as template, and wanted to apply the same bug fix to that file, the bug was gone! I did not change this file and still no bug at executing the Macro. This means to me that the bug is not actually in the file, but in a (hidden) setting in Excel.
If it's a phantom breakpoint:
1 Delete the offending line of code
2 Run the code again
3 Repaste the line
I found this laughably simple solution after spending a couple days wading through all the answers here and elsewhere. I figured, if I link it to my original question it might help some other poor chap, since the question it's on is VBA break execution when there's no break key on keyboard and this is more applicable.
Link to original answer
I faced the same issue today. Resolved it with these steps.
Create a new module
Move the procedure that is causing the issue to this new module.
Save project
Run macro again.
This time, the code execution will run till completion without any intermediate stops.
