Trigger Change Event When Nothing Is Changing
Sep 9, 2012
If no program (code) is running and Calculation is turned to ON, what expression could be placed into a cell that will change on its own that could necessarily and periodically trigger a change event subroutine. How can I trigger a change event when nothing is changing?
I have a situation where my code simply stops running so i need a change event to assess whether code is running (or not) and to issue a warning to the programmer that the code is, in fact, stalled. The change event subroutine has not only a warning system but a "timetorun" feature that will come back and warn again until the programmer can address the issue.
Unfortunately, I have to deal with this issue in a check and balance fashion because my many attempts to seek solutions to a stalled program (root cause) have failed.

I have a chart with 2 Y axis. I am attempting to write some code that will update both axis with the same max & min value that is triggered by the combobox selection. The code will update the axis but is not triggered by the combobox selection.

I have a user entering text into a textbox on my userform. The textbox is linked to a textbox change event. Unfortunately, the event is triggered as soon as the user enters the first character of their entry. I'm thinking that the textbox change event isn't the most appropriate for this scenario. What would I need to do to trigger the code (of the change event) with hitting ENTER when finished?

So, I have a worksheet with a bunch of combo boxes. The code for the worksheet is below. The issue I'm having is that anytime I drag and drop a cell anywhere on the page, every single control on the worksheet triggers. VB runs through all the code on the sheet, TWICE(I used the debugger extensively trying to find a solution), and causes dozens of successive re-calculations of the entire workbook, which has a couple of tables. This happens on any cell drag-drop on the worksheet, or when I click the command button on the screen.
I have no clue what is causing this. Even more bizarre, it seems to trigger a custom function which is located in a separate module, and isn't even utilized on the worksheet in question. I guess this is because it makes the whole workbook re-calculate?

I am working with a large legacy file/program which has a lot of issues. Foremost, and unfortunately this cannot be changed, is that all of the controls were placed directly on the worksheets instead of on Userforms.
I had previously posted code from the legacy file which may have been excessively complicated. So I edited my post to this simple example. Sheet1 has one textbox and one command button. Sheet 2 is blank.
If Sheet2.Activate is commented, everything works fine. If Sheet2.Activate is executed, then Excel crashes....

On my userform I have a frame. Within the frame, there are 6 option buttons. Can I trigger an event when when the user selects a different option button? I was expecting to see a Frame.Change method. But I don't. One solution is to insert code on each of the Option Buttons Change methods.

Is it possible to write an event trigger macro to format cells? Let's say I want to add a new information to the row which is after FinalRow. Can I force excel to detect the input and then format that new row as previous rows or something custom?

I am trying to write a worksheet_selectionchange macro in which the change is initiated only when certain cells are changed (B6:B9 and X9). I do not want the change to be initiated when any other cells on the worksheet change. B6:B9 and X9 are drop down boxes and the values within the drop-down boxes is variable.

I receive Argument not optional.

If Target.Column = 10 Then
Call GenerateEmail(Target.Address)
End If

I have a project report, which is user-configurable, allowing the user to customise the data that is displayed based on a number of parameters.
To ensure the report always prints neatly (the number of visible columns and rows varies, depending on the above parameters), so I have a macro that dynamically sets the print area of the worksheet.
At present, I call the macro from the workbook.beforeprint event, which works fine in terms of printing. Ideally however, I would like the macro to be called when CTRL+P is first pressed - i.e. the resulting 'print screen', containing a preview of the print out should reflect what will subsequently be printed, when the 'Print' button is then pressed.
I am not sure if this makes sense (Excel 2010 and 2013 are different from previous versions).

Is there a way to write a Worksheet_SelectionChange (ByVal Target As Range) event in module after creating a sheet in VBA? I constantly delete a sheet, then repopulate it with a new one that is empty, but I need to add some code that happens if they should change a particular cell. It worked when I ran it on a worksheet without refreshing, but as soon as I cleared and repopulated the sheet, it was gone. Is there a way to preserve this?

I have the following code, which works perfectly:
Private Sub Worksheet_Change(ByVal Target As Range)
Dim TotalDays As Integer
TotalDays = Range("C65536").End(xlUp).Row + 1
The code points to the next blank cell so the user can input a value. Each time the user enters a value I want to re-run the code so that the colour of the cell changes.
However I also want to perform various calculations on the sheet. However this means the sheet is being changed and so continually repeats my code.
How do I add the following, to my previous code?
Range("E8").Value = Cells(7, 6) * 2.5

I have a set of data in a given range with one column indicating "priority" of 0, 1, 2, or 3 for each row. I would like to be able to allow users of the file to filter the data simply by changing the text of a given cell, or by choosing among filter options from a drop down. For example, I would label the control cell "show items up to priority:" and then let them enter 1, 2, or 3.
The "auto filter" option won't work because if they use the "sort" options in the drop down it will mess everything up. I would only want to use the auto-filter drop down if I could suppress the sorting options and the other filter options. (I'm after custom options of <4, <3, <2, <1).
Also, the advanced filter method doesn't seem to work well because users would apparently have to re-run the filter each time they want to change the criteria range value.
I've heard of macros that can be triggered based on changes to data in a given cell, but how is this done in this situation?
I guess programming a custom drop down box for selecting 0, 1, 2 or 3 would work just as well as having them type the number in. But I'm not sure how this could be done either.

If for example cell A1 begins empty with no data in it other than a formula and something occurs to change the state of cell A1 to a value which triggers a change in cell B1 (a variable), can I use this to fire a sheet change macro ????
Wish to trigger a macro on sheet change based on every cell in column C, is this even possible ???
Or, is a change in a variable (C1) for example, the same as that of a DIRECT user keyboard input for example ???
Code:
Private Sub Worksheet_Change(ByVal Target As Range) Dim c As Range
If Not Application.Intersect(Target, Columns(3)) Is Nothing Then
Application.EnableEvents = False
For Each c In Target

I am sure that a worksheet change would be the best way to go for this, but I am unsure how to test for this.
I am looking to prevent users from using a select set of colors for highlighting. If the user tries to highlight using one of these invalid colors, I would like to flag a message telling the user that this color is reserved and highlight the selection to the previous color.
The previous color may be a tricky part as I do not know if this can be done.

I have an application that updates the text string in A1 every x minutes (time may vary). I'm trying to develop a toutine that will trigger a Macro/call a function/subroutine once only on each change of data (and then not trigger again until the next change...and must only trigger on change of data in this specific cell). So the timeline looks like this
start A1 = "Apples", Fire macro once
start + 10mins A1 = "Oranges", Fire Macro Once again
start + 25mins A1 = "Pears", Fire Macro Once again
etc.
Triggering the macro is no problem but constraining to one triggering is proving a problem (for me anyway) and is really holding up my application progress.

I have the code below that is two separate activities and I want to change the second activity from a cell trigger (Set KeyCells = Range("K42:AD42")) to a button trigger. I need to first to remain unchanged.
I'd be ok if this was just one macro that I could assign to a button but because its two and I need to write the second's to clicking a button I'm over my head.
Its occured to me while writing this that because it'll be a range of buttons I'll probably need to make each one an individual code? Is this the case? If so I may have to just keep this as it is.

I have a bit of code that calls a formatting sub depending on which cell is modified. It is triggered by the Worksheet_Change event, determines which cell is modified, and either calls the formatting sub or doesn't based on the location of the modified cell.
Some of the columns in the sheet have data validation with drop downs. If I select a value from the drop down, it doesn't trigger the Worksheet_Change. If I type a value into the same cell, it does.
This was apparently an issue in Excel '97, but supposedly fixed in '03?

Attached is book in which, when a choice is selected from Drop Down list in ColumnF the macro has to do the need.
When the macro was written it was working well. But when I tried to change it as a Worksheet_SelectionChange event nothing is happenning even though a choice is selected from drop down list.

Basically the situation I have is Sheet2 has many references to cells in Sheet1. Sheet2 is for all intents and purposes a kind of nicely formatted report form, and Sheet1 is the input form.
My ultimate goal is to automatically resize row heights on Sheet2 when cell contents change on Sheet2.
Using a worksheet_change event isn't working I presume because it doesn't see the formula output change as a worksheet change, the worksheet_change is firing only when the input is changed in Sheet1.
how can I capture these formula output changes on Sheet2 (triggered from input on Sheet1) OR is there a way of making a particular sheets rows always adjust in height to best fit?

Im trying to use an event change to change the sheet name based on a cell value, but my issue is how can I error trap if the sheet name is a duplicate? Here is what I have so far
Sub ChangeName()
On Error GoTo errhandler
Sheets(1).Name = Sheets(1).range("d10")
Exit Sub
errhandler:
MsgBox "sheet name is already exists"

I have a worksheet called "Roster" with a list of names from D7:D17 each person on the list has a separate sheet that is called by their name. the sheets are not linked up. the names were just manually typed into the list and into each sheet name.
If any name is changed on the list on "Roster!D7:D17" i would like the sheet that has that name to change as well.
This is the code that i was sent, but i do not know enough about VBA code to understand exactly what is happening, thus i cannot diagnose the problem. I placed the following code into the page "Roster" (by right-clicking and then pasting the code) then i closed, but nothing happens. I can mess with the code and get an error message. but that is about it. error messages usually say something about the debugger, or runtime error or something.
there is the
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
OldVal(0) = OldVal(1)
OldVal(1) = Target(1).Value
End Sub

I have a workbook, that when opened the first time needs to prompt the user to save it. I got that working with no issues by using
Private Sub Workbook_Open()
SaveOnOpen
End Sub
where SaveOnOpen is a procedure in another module. What I would like to do now is re-assign the Workbook_Open sub to be set to null, so that it doesn't run any more. Is it possible to somehow assign Workbook_Open to call a null procedure, as opposed to setting up an onTime call to delete the code itself?

I have a user input box (VBA) with two columns of data entry. The leftmost column has text boxes labeled color1, color2, color3, etc.. The rightmost column has text boxes labeled tag1, tag2, tag3, etc..
I have the TAB sequence set to go from color1 to tag1, color2 to tag2, color3to tag3, etc..
A user can inadvertently tab over the color1 (or color2, etc. columns) into the tag1 (or tag 2, etc. columns) column without entering data in the color column.
Is there coding to allow a TAB key entry to be a Change Event such that, if a user TABS out of color1 without entering data, a MsgBox could signal that they must enter data in the color1 field before they can continue?
Alternately, can you suggest a different approach? The goal is to require an entry in the leftmost column (color1) before they can proceed to the tag1 field. Of course, they are given a "Cancel" option.
