I am trying to set an event that it is triggered when the zoom on the sheet is changed.
In particular, I would like to make column width autofit in a range with the following code.
Range("A1:M27").Columns.AutoFit
In fact, if the zooom on the sheet change (ActiveWindow.Zoom), some cells may become #######.

I have an Excel Sheet with some macros. Also, I have some navigation shapes and images on my sheet. I want users of this sheet, cannot change this shapes and images positions, can't select them and can't move them.
Is there any way to Protect some specific objects?
Regards.
I believe this is an age old question ever since Shapes were added to MS Excel and the answer to which I myself was looking for many years already.
I just found out 3 days ago, on my own, how to lock MS Excel Freeform shapes like Choropleth Map shapes from being moved around, reformatted or worst, deleted, all WITHOUT needing to lock the WorkSheet, or eventually the WorkBook.
And I think I must share my discovery with the world because everyone wants to lock their Shapes!
Steps: (I work with Excel VBA and with msoFreeform shapes mostly but I think any shape should be working and manually added shapes through Excel UI should work too and in other Office Apps as well)
1.(yourWorkSheet or )ActiveSheet.Shapes.AddChart (through VBA but MAYBE you can add chart through Excel UI and then delete the only chart)
(no need for any other parameter because we just need the chart container, "ChartObject")
2.If you don't have some already, create a shape either through Excel UI or through VBA with AddShape method or BuildFreeform on the Chart directly or on to the worksheet.
3.Copy/Paste the created shape (if created through Excel UI or through VBA on the worksheet) on to the BLANK Chart Container. (NOT drag and drop)
4.Format the ChartContainer Rectangle window as required (try "No Fill & No Outline") through VBA or Excel UI
5.There are 3 options regarding protection of a Chart
(Embedded chart here because I don't work with Chart Sheets, may be this might work with them)
source:[https://peltiertech.com/Excel/ChartsHowTo/ChartProtection.html]
But here, only the relevant 2 will be shown:
5(a)ActiveChart.ProtectFormatting = True
That protection will block any formatting changes on the Shape and the Chart via "Chart Tools Menu" or "Drawing Tools - Format Menu" or moving or resizing with mouse or deleting BUT will show the ChartContainer window upon Selection via Mouse but non-selectable via VBA
eg. yourworksheet.ChartObjects("YourChartName").Chart.ProtectFormatting=True
5(b)ActiveChart.ProtectSelection = True
That will stop the shape or the chart from being selected altogether so this is the end of story
eg. yourworksheet.ChartObjects("YourChartName").Chart.ProtectSelection=True
The best thing about this method is that the shape can still be accessible through VBA like
eg.yourworksheet.ChartObjects("YourChartName").Chart.Shapes("YourShapeName or Index").whatever
except Shape.Select which should be obvious and there is NO need to lock the Worksheet or Workbook at all.
NB:1)The interesting finding here is that the 2 protections do not replace each other (if applied one after another) but more like stacked with each other meaning if both (if you really want) were set True first and then after setting either one False, the other restriction still remains.
2)Even if selection is protected as above, the chart can still be accessible through the Selection Pane, therefore:
Application.CommandBars("Selection and Visibility").Enabled = False
and also blocking the Worksheet Export are advisable but I think these are overkill nonetheless included for completeness' sake.
Discovered and tested on MS Excel 2010 so YMMV.
Nay Lynn's answer caused my Excel to crash. Specifically with the .ProtectSelection property being enabled (using Microsoft365 Excel). . . Excel VBA's Intellisense shows the property, so it is legitimate, but everything would be fine until the chart was selected. Playing around with this idea though, I did find a great work around.
1. Place a Chart on your sheet. Make it span across the area you want to protect
(we will expand the size of this chart later).
a. Leave Fill of Chart at Default until a later step (this helps ensure the
next steps are successful).
b. Delete all the elements present for the chart (Series label, Title, Etc.)
c. Shrink the "Plot Area" box leftover to as negligible as possible.
d. CRITICAL: Right Click the chart and choose "Select Data" - use the
option to remove all the data in the boxes of this dialog, otherwise when
you select the Rectangle added below, it will show the data references as
selections in the Worksheet behind it.
2. Insert a Rectangle into the Chart. It will have the default colors.
3. Tap `Esc` to clear the selection. If you select the shape and try to move it
around, it will take precedence over the Chart itself (this is how we'll trick
Excel later).
a. Confirm this does not allow the shape to be pulled beyond the border of the
Chart.
4. Set Fill of Chart to be "No Fill"
5. Expand the Rectangle's size to match the size of the chart.
6. Set Fill of Rectangle to be a color with 100% Transparency (NOT the same as "No
Fill" - this is critical)
a. You should be able to see all of your shapes, etc, but not touch them if you
click where the rectangle was, and trying to click and drag will also fail since the
Rectangle takes selection precedence and is also bound by the chart.
7. Set the fill of the Rectangle back to a color with 0 transparency (we need to
find the edge of the shape)
8. Select the Rectangle's border and it should then select the Chart instead (you
should see the chart Format option appear).
9. Expand the Chart's border to the ends of the Excel Sheet (ensure the top left
corner sits in the top left corner of the sheet by dragging it). You can also set
the height/width to an absurd number that users will get fed up with trying to find
if you do not wish to expand it across the entire boundaries (or if there's a hard
limitation - I did not try to expand across the entire sheet, but went to "BO400"
with no issue.
a. Expand the Rectangle to fit the Chart once again if it did not expand
automatically (in my case it did, but I cannot guarantee this behavior)
b. If you have any Buttons that DO need to be clicked, place this chart
at the bottom, place all the buttons/shapes etc. that need interaction to
the top, then bring the chart up a level until all the items needing
protection are hidden.
c. Change the Transparency back to 100%
10. After you have the Chart expanded properly, you will need to use a bit of VBA
to ensure the Chart's Formatting is protected as Nay Lynn mentions. Get the
Chart's name by selecting the border, and institute some VBA Code that gets
toggled based on your needs (you might want to include an unprotect sub
as well just in case).
Example:
Sub Protect_Sheet_With_Chart ()
dim sht as Worksheet
dim chrt as Chart
Set sht = ActiveSheet
'You can use a sheet by name for the above as well - make your code robust.
Set chrt = sht.ChartObjects("ChartNameFoundFromStep10").Chart
chrt.ProtectFormatting = True
End Sub
Sub UnProtect_Sheet_With_Chart ()
dim sht as Worksheet
dim chrt as Chart
Set sht = ActiveSheet
'You can use a sheet by name for the above as well - make your code robust.
Set chrt = sht.ChartObjects("ChartNameFoundFromStep10").Chart
chrt.ProtectFormatting = False
End Sub
11. After you protect the Chart, selecting it and deleting will not
actually delete it, NOR the rectangle, so it can't be removed!
12. Protect your code somehow and you'll be set!
I have an excel workbook with multiple sheets that aggregate costs and revenues of different technological components (set up in different sheets) in a system.
I want to have a main worksheet, where users can change a small selection of important variables from the technology sheets. I also want those important variables to be defined and editable on the technology sheets.
I've been using named ranges to manage variables, but I'm not sure how to link two cells on different sheets to one variable. For example, I want to name a variable "oilprice" that is referenced in different formulas. I want to be able to change the variable "oilprice" from the main worksheet and the electricity technology sheet in my workbook.
Similarly, I want to be able to check a box on both sheets for "Turn on Electricity" and have the checkbox on the other sheet change as well.
I've been looking around on google and stackoverflow but can't find an answer. Thanks!
Named range, option 1: "override" style formula
With named ranges, you are not able to update the value from multiple cells. You could use logic in a formula to look at a "override" cell and pass that value to the actual named range. This works if the number of overrides is small. That style of formula looks like:
=IF(ISBLANK(oilprice2), oilprice1, oilprice2)
Where oilprice1 and oilprice2 are the cells that hold possible values. Note that there is an implied order in these which can get confusing after a while. That is, if oilprice2 has a value, it will not change oilprice1 nor will oilprice1 be considered.
Named range, option 2: scroll bar or spin control
Another option similar to the checkboxes below, is to use a spin control or scrollbar control to update the values. Those work across multiple sheets.
Checkboxes across sheets
For the checkboxes, this is handled by the Cell Link. You can set as many checkboxes as you want to control a single cell's value.
Here is an example with two checkboxes sharing the same Cell Link = $C$2. They both change when one is clicked.
Okay, I figured out how to have two cells to refer to the same value.
I named a range "oilprice" on the "electricity" sheet.
The cell to input oilprice on the "main" sheet has the formula "=oilprice" and is named "oilprice2", showing the value on the "electricity" sheet "oilprice" named range.
Then I made the following vba code which updates the "oilprice" cell on the electricity sheet when you change the "oilprice2" cell on the main sheet and reverts back to the formula showing "oilprice":
Private Sub Worksheet_Change(ByVal Target As Range)
If Not Intersect(Target, Target.Worksheet.Range("oilprice2")) Is Nothing Then
Application.EnableEvents = False
Worksheets("electricity").Range("oilprice").Value = _
Worksheets("main").Range("oilprice2").Value
Worksheets("main").Range("oilprice2").Value = "=oilprice"
Application.EnableEvents = True
End If
End Sub
So, I've created a dynamic range for a chart, that's all well and easy.
However, in this chart there are two lines, but I only want one of the lines to show up under certain conditions, else it displays nothing! So I've tried creating my dynamic range as follows
=IF('WorksheetName'!$M$10 ='WorksheetName'!$F$31,'WorkSheetName'!dynamic_range, #N/A)
The problem is that when I do this the chart freaks out. It gives me this error:
Your formula contains an invalid external reference to a worksheet.
Verify that the path, workbook, and range name or cell reference are
correct, and try again.
If I click "ok" half the time it shows up correctly (that is, the second line disappears and the chart adjusts accordingly) and the other half the time it glitches.
Basically, how do I create a dynamic range for graphing that the chart will understand when I want it to do NOTHING and when I want it to display the range?
You need a second source range, that's cells are just empty. Applying your approach to switch between the filled range (intended to be visible) vs. the empty range (will be invisible), shall solve the issue. Note: The chart parameter "Show empty cells as:" should be set to "Gaps". (Refer to the Hidden and Empty Cells options in the chart's Select Data dialog. This is applicable to X/Y charts mainly.)
I have a userform in Excel 2003 which contains some MSForms.Label controls. I want to set the .BackColor property of each of these controls such that they match the color of some individual cells on a worksheet.
To do this I am reading the .Interior.Color property of those cells, converting it to hex and using that value to set the .BackColor property of the Label objects.
My problem is that the value coming out of .Interior.Color is almost always incorrect the first time it is read. I have tested this by running the following command in the VBA editor immediate window:
Print Hex([sourceCell].Interior.Color)
This command almost always gives the wrong value the first time round, but gives the correct value from the second time onwards. If I change the fill color of [sourceCell] and run the command again it will do the same thing, i.e. wrong value first time, right value second time onwards.
The cells in question are all filled with colors from the chart lines/fills color selection (i.e. the two bottom rows you can see in Excel's "Format Cells" dialog under the "Patterns" tab). These colors have been modified by me to give a custom set of colors and, tellingly, the "wrong" values seem to match Excel's defaults for the customized range of color picks (i.e. the default chart line/fill colors you get when you start a new workbook).
Has anyone else experienced this behaviour/have a workaround? When I try to read the values twice at runtime it doesn't work, i.e. it doesn't switch to the correct value. The code must be stopped and the userform reloaded to force the "correct" values to come out.
Kludge/workaround via Application.OnTime.
If I run the userform prep code to set the label objects' backcolors with the userform hidden, then set the main code to run from an immediate OnTime event (making sure to re-run the prep code as part of the OnTime) then I can force Excel to give me the correct "second time round" values when showing the form.
This works for me:
MyForm.MyControl.BackColor = Range(myrange).Interior.Color
.Interior.Color returns a Variant containing the RGB of the sampled range.
.Interior.ColorIndex always returns -4140 or something weird, probably because .ColorIndex is peculiar to Excel2003's color limitations.
ActiveX combobox objects in Excel do not behave well when their ListFillRange refers to a formula-based Named Range (Defined Name).
I think I have encountered other errors and possibly even Excel crashes thanks to this, but right now all that happens is the combobox_change() event is triggered anytime ANY cell in the workbook is changed.
I am not sure if this is really a bug, or if there is a fix, or a workaround. If it is a bug, how do I report it to the Excel people?
And finally, the real meat of my question is "How do I work around this issue best?" I would like to have some formula-based named ranges, but it seems like this won't be possible.
To reproduce this bug, do the following:
Create a new workbook. On Sheet3, create a small table 3 columns across, and several rows high.
Create a named range with this formula (or an equivalent): =OFFSET(Sheet3!$A$2:$C$36,0,0,COUNTA(Sheet3!$A:$A),COUNTA(Sheet3!$4:$4)) To do this use Input>Name>Define. Name the range something like "demoRange"
Go to Sheet1 and create a combobox, (it must be on a separate sheet). (Use the Control Toolbox menu, not the Forms menu).
Click on the Design Mode button (the blue triangle with pencil), then right click on the combo box and go to Properties.
In the properties window for the combobox, change the ListFillRange property so that it points at the named range you created in step 2 ("demoRange").
You may want to change the ColumnCount property to 3, and the ColumnWidths property to "50,50,50"
Set the linkedCell property to cell "A1" by typing A1 in the linkedCell property.
Close the properties window, and double click on the combobox to define its change() event.
Put a Debug.Assert(false) or Msgbox("demo") line in the subroutine for the new combobox's change event.
Exit design mode
important - Now select an item in the combobox. The event should trigger normally the first time. (The bug will not show if you don't do this step--something must be selected in the combobox)
Edit cells anywhere in the workbook [Edit] or any other open workbook [/edit], on any sheet and any location. Each time you edit any cell, (at least for me), the onchange event for the combo box is run.
Again, is this normal, and what is the best alternative for what I am doing? This combo box gets linked to various cells, and is supposed to be a replacement for the tiny font in the data validation dropdowns excel provides by default.
My advice is to never use ListFillRange and LinkedCell. They are just trouble. Fill your listbox with List and use the Change event to write to the cell. Somewhere, maybe the Workbook_Open event, fill the listbox
Private Sub Workbook_Open()
Sheet2.ListBox1.Clear
Sheet2.ListBox1.List = Sheet1.Range("demoRange").Value
End Sub
Then in the change event in the Sheet2 module, check that something was clicked and write it to the cell
Private Sub ListBox1_Change()
If Me.ListBox1.ListIndex >= 0 Then
Sheet2.Range("A1").Value = Me.ListBox1.Value
End If
End Sub
I have a few options available that I am aware of thus far. The best I can come up with is this:
Avoid directly using formula-based named ranges. Instead, define a subroutine that will check whether the defined range "demoRange" should be changed from what its current value is. Run this subroutine on the workbook_open and sheet3_deactivate events. If needed, prompt the user to ask if it's all right to update the named range. [edit] The macro that updates "demoRange" could probably just copy from a "demoRange_FormulaBased" named range into "demoRange" which would be static. [/edit]
This solution works well because you can keep using the linkedcell property, you don't have to use VBA to populate the comboboxes, and the named range can still be used for whatever other purposes it already had. Avoid using the onchange event to run this new subroutine, since it might end up being triggered thousands of times if a user opens the Find/Replace dialog and chooses "Replace All".
