Answer 1

If you minimize the Remote Desktop window, Windows switches the remote session to the GUI-less mode and does not display windows and controls. As a result, TestComplete (or TestExecute) will be unable to interact with the tested application’s GUI, as it does not exist and your automated GUI test will fail. To work around the issue, you can change the Remote Desktop’s registry settings on your local computer (where you launch the Remote Desktop): On your local computer, close all open Remote Desktop sessions. Launch the Registry editor (regedit.exe). Navigate to one of the following Registry keys, depending on whether you wish to modify the Remote Desktop settings only for the current user or for all users on the computer:

HKEY_CURRENT_USER\Software\Microsoft\Terminal Server Client HKEY_LOCAL_MACHINE\Software\Microsoft\Terminal Server Client Create a DWORD value named RemoteDesktop_SuppressWhenMinimized and set it to 2.

Or you can do it programmatically by following steps:

• Transparent the window
• Restore the Window
• Capture
• Minimize it again
• Remove transparency
