I have started using VS Code for work instead of Anaconda and there are some weird observations which I am not able to figure out.
If I try to execute some code in a cell in the interactive window, many-a-times, only output remains available and the input code automatically gets hidden. For eg. I type the following and execute:-
And this is what I see at the window:-
Similarly, there are some variables which I have already defined but they don't show up in the Jupyer:Variables tab. For eg. there is a variable _link_name_to_index which is not visible in the tab as shown below:-
However, when I execute the same in the window, I can see the values of the dictionary as expected:-
Maybe it is just a matter of some settings, but I still couldn't find out which one. Also, I know I have put a lot of images, because it is not a code doubt as such, rather more of a tool doubt. I have taken only one particular example here, but I face this issue often. I am using VS Code version 1.75.0 in Ubuntu 20.04, using Python 3.9.12 in a virtual environment, if it helps.
This is a bug in the latest Version of VSCode (1.75). It is tracked in this issue. For now, the only option seems to be downgrading to v1.74.x
I am working on a VBA GUI that I have not developped by myself.
I do not really know VBA langage and I need help.
I am trying to drive an electronique card plugged as USB with that GUI.
The problem is that I am trying to use NETComm.ocx to send instruction to the device but I have an issue that is knowed by the GUI developper and voluntary ignored because he does not have the issue. It seems to depend of the computer.
I am adding NETComm.ocx and MSComm32.ocx files to the path where Excel VBA is looking for them. When I check in the References panel, it seems to work well but when I am executing the code, I have a
"Run-time error '424' : object required.
When I clic "Debug" it highlight the following line :
NETComm1.CommPort = VirtualCommPortNumber
VirtualCommPortNumber is an integer.
It seems like it does not know NETComm but I do not know how to do to fix that.
Thanks for your help.

You need to Copy NETComm.ocx and MSCOMM32.OCX to C:\Windows\System
I think the Paths are hard-coded in these files, so they can be only registered from here.
Run cmd as administrator and
Type regsvr32 C:\Windows\System\NETComm.ocx and ENTER
Type regsvr32 C:\Windows\System\MSCOMM32.OCX and ENTER

thanks for your amazing support!
Now i have again a question. To get access to some raw datas (i'm working in a call center) we using a website to get an CSV/xls file from our SQL Database (the IT Department doesnt allow me to get direct access to the SQL database).
For an automatic update of my sheet i use an shell command to trigger chrome with the right parameters in the link (chrome starts the download).
Everything works fine but, when i trigger Chrome per shell, i have to minimize chrome again (otherwise you can't see the Excel screen). So i can't find an command to minimize external windows so i'm using shell to minimize all, after that i maximize excel again, works great, but after excel has done the updates, it should activate "VLC Media Player", i tried to use AppActivate for that, but its just blikink orange in the taskbar and dont get focus.
Can you help me?
I can share you the code but it's really just the AppActivate() line that interest you :)
Thanks again!

NirCmd from NirSoft is what you need.
I'm using the Ribbon control located on CodePlex, and following the tutorial located here . Once I add the reference, and the proper code in the designer I get this error when I try to view the form:
Exception of type 'System.ComponentModel.Design.ExceptionCollection' was thrown
And I cant figure out what I'm doing wrong. Anyone worked with this control and know how to resolve this issue?
Interesting; I just ran into this same issue with one of my own forms; which is how I found your relevant and recent question.
Here's how I solved it:
Open two instances of Visual Studio. Open the same project in both.
In one instance, goto Debug->Exceptions and enable all the 'Thrown' options to stop at first chance exceptions. This will stop the debugger when the exception is generated.
In the same instance, select Debug->Attach to Process, select devenv.exe.
In the other instance, open the form to cause the exception
With any luck the first instance should stop somewhere that yields a more relevant exception.
In my case it turned out to be something that I should have conditioned with:
if (!DesignMode)
{
// Do something that should only happen at runtime
}
Don't forget turn turn off all those 'Thrown' options later.
A workaround for me was:
Right-click on the form and 'View Code'
Keep the code loaded in the editor and then attempt to view the designer again.
This feels very glitchy and I cannot confirm whether it's a problem with my code (as I'm working on an entirely new codebase) or whether it's a VS2012 bug. If I find out, I will report back.
Since the solution outlined by pilotcam didn't work for me, I took a different approach:
Make a SVN commit for the file.
Open the “*.designer.cs” file of the form that shows the error in source view.
Remove larger blocks of form element declarations.
Fix all compilation errors with ReSharper (i.e. ensure that nothing is red anymore on the side-indicator).
Save the file. No need to compile.
Open the Windows Forms Designer of the form.
If the error still shows up, do a SVN revert to go back to the initial state.
Repeat steps 2 to 7 until the error does not show up anymore.
Now you’ve encircled the erroneous child control that causes the error.
Repeat steps 2 to 7 with a smaller amount of controls you remove, until you have only one control left.
In my case it was a user control inside a group control inside a tab control, so I first identified the tab control, then the group control and then the user control.
You could isolate the user control inside a new form to further investigate. In my case it was rather easy; I put checks for design mode around most of the functions inside my control to ensure the code only gets executed if the control is not in design mode.
This fixed my error.
I had the same issue and none of the above answers solved the problem.
At the end, emptying the "bin" folder and rebuild has worked for me.
Let me add two more cases when such exception can happen, along with when control tries to do something that is not allowed under design mode:
When it's impossible to compile the user control.
When designer code contains multiple similar (or identical) lines with initialization of same controls or properties, this can easily happen on merge.
All that cases produce same extremely meaningful error message, and in this particular two debugging of Visual Studio won't help, so I just ended up with bisecting my designer code.
[ReadOnly(true)]
[Browsable(false)]
Above all properties worked for me
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,

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.
