Greetings,

I have posted on this a few times now, but as of yet, no one has been able to assist me. Perhaps the code below will help people get started.

Here is what the code should do. If my ToggleButton, named "Edit", is set to True, then it should run the sub "Alter" below. At this point, the user has the following options as long as Edit.Value = True:

Right-Click, which should run function Change_Shape
Left-Click, which should run function Create_Shape
Press ESC, which will exit the function completely and set Edit.Value = False

1) The code works, with the following problems. Right-clicking causes Change_Shape to run infinitely.

2) Left-clicking works for the most part, but randomly, it seems to freeze and I can't break out of the code unless I hit ESC.

Can anyone assist me in modifying the Alter function at the bottom to avoid these problems? It would be greatly appreciated. I apologize for the long posting of code, but it is necessary to get the code to work properly.

Excel Facts

Create a chart in one keystroke
Select the data and press Alt+F1 to insert a default chart. You can change the default chart to any chart type
Have you tried entering Exit Do after the Change_Shape, as well as after the Connect_Shape? Please try it, and report back.

If I add an Exit Do in each of those If statements, it will break out of the code, only allowing me to change or create the shape once. Then I would have to unclick and re-click edit in order to paste another shape. I want to be able to use the left-/right-click functionality in this way for the duration of Edit being toggled on.

Try, instead:

Code:
Sub Alter() 

    Do 
        If GetAsyncKeyState(VK_RBUTTON) < 0 Then 
            Change_Shape
            GetAsyncKeyState(VK_RBUTTON) = 0

        ElseIf GetAsyncKeyState(VK_LBUTTON) < 0 Then 
            Connect_Shape 
            GetAsyncKeyState(VK_LBUTTON) = 0
        
        ElseIf GetAsyncKeyState(VK_ESCAPE) < 0 Then 
            Sheet3.Edit.Value = False 
            Exit Do 
        
        End If 
    Loop 
    
End Sub

The GetAsyncKeyState(VK_RBUTTON) = 0 returns a Compile Error: Function call on left-hand side of assignment must return Variant Or Object.

Time for a VBA guru! Me, I'm just a dabbler in VB, and the logic "seemed" good, to me. But, I see that I was wrong.

Hope some other person sees your post and helps you out.
