I use the following code to click on a button to display another form, to click on it:
Dim hwnd As Integer = FindWindow(vbNullString, "Virtual CDRom Control Panel")
Dim x As Integer = FindWindowEx(hwnd, 0, vbNullString, "Driver Control ...")
SendMessage(x, BM_CLICK, 0&, 0&)
Thread.Sleep(200)
hwnd = FindWindow(vbNullString, "Virtual CD-ROM Driver Control")
Debug.Print(hwnd)
The problem is that when he gets to
SendMessage (x, BM_CLICK, 0 &, 0 &)
to press a button, it stops the code there until I exit the window that appears. I want to be able to continue without leaving the box from the next line
hwnd = FindWindow (vbNullString, "Virtual CD-ROM Driver Management")
finds a popup and clicks on a button inside that window.
Any help would be wonderful !: O)
