The "Undo" Problem after running a macro

[AlvaroPers]

thread560-95318

Hello,
I have the following situation:

I run a program (using visual basic under Visual Studio) to change instances name. The program works just fine.
I have the following lines in case the user "cancel" the renaming and wants to go back with the changes:

Private Sub Cancel_Click(sender As Object, e As EventArgs) Handles Cancel.Click
If flag = True Then
myCATIA.StartCommand(iCommandId:="Undo")
End
ElseIf flag = False Then
End
End If
End Sub

I noticed that once the renaming took place, before closing the form if I go to the CATIA window and make a mouse click at anyplace in the geometric area, then "undo" action works well.
In the opposite, if I don't click the CATIA window the behavior is different, the "undo" action doesn't work, and the " Unavailable command: Undo" appears.
I've tried unsuccessfully to use the API in order to use the functions "FindWindowsEx" to get the window and then make a "postMessage" to simulate a mouse click, but I couldn't get it work.

My question is, has anybody found a solution to use the undo command after running a program?

Thank you.
Alvaro.

It is solved, since when using the resulting ".exe" program the undo works just fine.
