Modeless form that still pauses code execution

Question

Is there anyway to have a userform that acts modeless, while still pausing code execution like a modal form?

I\'d like the userform to show, but still allow interact

Answer 1

The Best method would be to use two different subs. I was able to solve this problem without splitting my sub as follows:

Public Mode as Boolean

Sub Stuff()
    If Mode Then
        Goto Continue
    End If

    'Code before Userform

    Mode = True
    Userform.Show vbModeless
    Exit Sub

Continue:
    Mode = False

   'Rest of your code

End Sub

I made "Mode" a global variable because I use this userform for multiple subs. If you are using a single sub you can use it locally. I also made "Mode" false when opening this workbook by going under "ThisWorkbook" Tab and adding the following code:

Private Sub Workbook_Open()
    Mode = False
End Sub

This again will only be needed if you use your userform for more than one sub. Last add this code under your Userform code when your proceed button is pressed.

Private Sub Confirm_Click()
    Userform.hide
    if Mode Then
        Call Stuff
    End If 
End Sub

If you are only are using the one sub method skip the if statement and just call the sub.

You should be able display the form as vbModeless and only execute code when specifically requested, i.e., from a CommandButton or other control.

You then leave the form visible/shown until it is specifically closed, via the "X" button or via another control which calls the UserForm_Terminate event.

In order to achieve this, you may need to move some of your executable code in to another subroutine and/or module, and call this subroutine for example from a CommandButton_Click event.

You already have a subroutine somewhere that contains a line like:

Sub ShowTheForm()

    UserForm1.Show vbModeless
End Sub

So the form is displayed properly to allow user-input to the parent application.

You don't really need to put any other code in the above module. We will put the other code in other modules/subs, and then call it from user controls like command buttons.

Example:

Take all of your executable code, and put it in another subroutine (and if it suits your organizational preference, another module), like:

Sub MyMacro(msg$)
    MsgBox msg
End Sub

On the UserForm, add a command button and assign it the following code:

Sub CommandButton1_Click()
    MyMacro "hello"
End Sub

Now, the form will display until the user clicks the "X" button. Code will only run when called from the command button.

EDIT FOR CLARIFICATION

You don't need to "pause" the execution using this method. Execution ends once the form is displayed modelessly, and the form persists. The object has some events which you may use to trigger further execution of code.

Here's what I do.

This example is for a form I called "Find Header". The code tries to find several column headers, but the markers for a few of them may be missing (and the header text may have been overwritten with something random), so I may need to pause and ask the user to locate (click on) some of the headers for me:

First, put this declaration in a standard module:

Public bDlgFindHeaderIsShowingModeless As Boolean

Then, put this in the event procedure for any button or other control that dismisses the modeless dialog, such as the Click events for the form's OK and Cancel buttons:

bDlgFindHeaderIsShowingModeless = False

Then, put this wherever in your code you want to show the modeless form while paused for user interactivity:

bDlgFindHeaderIsShowingModeless = True 'init
frmFindHeader.Show vbModeless
Do
    If Not bDlgFindHeaderIsShowingModeless Then Exit Do
    DoEvents
Loop

Yes, it churns the CPU, so you might not want to do it if you're on a single-core processor and there are critically important background processes running. But it works; the user is able to easily and smoothly interact with Excel while the modeless form displays. The user doesn't feel like they are fighting an endless loop.
