How make VBA run on clicking any checkbox in a userform? - vba

Question

I have a userform with a multiple frames, all filled with multiple checkboxes. I've named the checkboxes to their corresponding Excel cells. Now I want to make VBA run on clicking any of these checkboxes on run time. I know I can do this by creating a click-sub for every individual checkbox, but there must be a cleaner way to do this.
So far I've tried to put this code in the userform_Click and userform_Mousedown events, but they don't run when I click the checkboxes. Does anyone have an idea how to do this?
Dim iControl As Control
For Each iControl In Me.Controls
If TypeName(iControl) = "CheckBox" Then
If iControl.Value = True And Range(iControl.Name).Value = "" Then
Range(iControl.Name).Value = Format(Now, "dd.mm.yyyy")
ElseIf iControl.Value = True And Range(iControl.Name).Font.Color = vbWhite Then
Range(iControl.Name).Font.Color = vbBlack
ElseIf iControl.Value = False And Range(iControl.Name).Value <> "" Then
Range(iControl.Name).Font.Color = vbWhite
End If
End If
Next

As SilentRevolution said - you need an event to fire when you click the button. You're just after a single procedure to fire all check box click events.
So:
Create a class module called cls_ChkBox.
In the class module you'll add the Click event code:
Option Explicit
Private WithEvents chkBox As MSForms.CheckBox
Public Sub AssignClicks(ctrl As Control)
Set chkBox = ctrl
End Sub
Private Sub chkBox_Click()
ThisWorkbook.Worksheets("Sheet1").Range(chkBox.Name).Value = Format(Now, "dd.mm.yyyy")
End Sub
Now you just need to attach the chkBox_Click event to each check box on your form. In your user form add this code:
Option Explicit
Private colTickBoxes As Collection
Private Sub UserForm_Initialize()
Dim ChkBoxes As cls_ChkBox
Dim ctrl As Control
Set colTickBoxes = New Collection
For Each ctrl In Me.Controls
If TypeName(ctrl) = "CheckBox" Then
Set ChkBoxes = New cls_ChkBox
ChkBoxes.AssignClicks ctrl
colTickBoxes.Add ChkBoxes
End If
Next ctrl
End Sub
Each check box is given its own instance of the class, which is stored in the colTickBoxes collection.
Open the form and the cell in Sheet1 will update to show the date depending on the name of the check box.

You need an event to run code, if there is no event, the macro cannot start. I don't know if there is a single event that triggers for any button or checkbox that is clicked.
If the code you want to execute is the same every time except the control, you could write a private sub in the userform module which is called for each event, the private sub can take an input between the () for example.
Private Sub CheckBox1_Click()
Call ExecuteCode(Me.CheckBox1)
End Sub
Private Sub CheckBox2_Click()
Call ExecuteCode(Me.CheckBox2)
End Sub
Private Sub CheckBox3_Click()
Call ExecuteCode(Me.CheckBox2)
End Sub
Private Sub ExecuteCode(IControl As Control)
If TypeName(IControl) = "CheckBox" Then
If IControl.Value = True And Range(IControl.Name).Value = "" Then
Range(IControl.Name).Value = Format(Now, "dd.mm.yyyy")
ElseIf IControl.Value = True And Range(IControl.Name).Font.Color = vbWhite Then
Range(IControl.Name).Font.Color = vbBlack
ElseIf IControl.Value = False And Range(IControl.Name).Value <> "" Then
Range(IControl.Name).Font.Color = vbWhite
End If
End If
End Sub

I just learned this today and thought it might help? Most of the questions, and responses for that matter, to questions regarding checkboxes, listboxes, etc. seem to not distinguish between those forms are inserted directly on the worksheet or are imbedded in a UserForm.
This may work for a checkbox - it works for a ListBox on a UserForm. If you want code to run after a selection, the code you must write has to be in module of the UserForm. I had no clue how to access. Once you have inserted a UserForm in your VBE, add the ListBoxes or whatever to the UserForm. Right click on the UserForm in the upper left project window and select "view code." Here is where you'll place the code, in my case a "change event" such that after a selection is made from the ListBox, other code is automatically run. Her for example:
Sub lstBoxDates_Change()
Dim inputString1 As String
inputString1 = Format(UserForm1.lstBoxDates.Value, "mm-dd-yyyy")
Call EnterDates(inputString1)
Unload Me
End Sub
To explain: Again this code is in the UserForm Module. I named my ListBox,
lstBoxDates. In my main code that I call - EnterDates, I use the variable name = inputString1. The value or date that I have selected from the ListBox is captured from the UserForm1 by UserForm1.lstBoxDates.Value - and I format that to a date, otherwise you see just a number. This is for only one selection.
Because I Dim here, no need to Dim in your main code. The sub for the main code
needs to accept the variable you are passing to it:
Sub EnterDates(inputString1)
This is very generalized but maybe something will click so you can get what you are after. I hope so, for I've worked on this a full two days!!
