what the best way to use Wait for Msgbox with out getting a resumable sub error?

B4X: 
'some code before msgbox'

        Dim message, title As String
        Dim result As Int
        
        title = "Title"
        message = "Message"
        Dim icon As Bitmap = LoadBitmap(File.DirAssets, "Question.png")
        Msgbox2Async(message, title, "Yes", "No", "", icon, False)
        Wait For Msgbox_Result (result As Int)
        
        If result = DialogResponse.POSITIVE Then
            If File.Delete(Main.strMMDirLoc, FileName) = True Then
                bWriteFile = True
            Else
                bWriteFile = False
            End If
        End If
        
'other code to execute here'

It seems like you are using it correctly, so if you are getting an error it probably is being caused by some conflict with the code before or after this code.

Please post the events from the log window so we can see more details.

well when I use the code this way...

B4X: 
result = Msgbox2Async(message, title, "Yes", "No", "", icon, False)

I get this error:

That error is expected because that is not the way to use Msgbox2Async.

Your first post is doing it right - do you get an error with the first method?

You should show your Sub.
To return a value it should be like this
B4X: 
Sub Name (myvariable as Int) as Resumablesub

See this tutorial on how to make a resumable sub return a value:

[B4X] Resumable subs that return values (ResumableSub)

Remember that that a call to Sleep or Wait For in a resumable sub causes the code flow to return to the parent. Example: Sub Button1_Click Sum(1, 2) Log("after sum") End Sub Sub Sum(a As Int, b As Int) Sleep(100) 'this will cause the code flow to return to the parent Log(a + b) End Sub...

B4X: 
Wait For(MyResult) Complete (Result As Boolean)
Log("HI! I am " & Result)


Sub MyResult As ResumableSub
    Return True
End Sub
