Hello, I'm using following code to try to open a RDP-files located on the local c:\-drive.

The function returns 31, which means no associated programm found. I can start the RDP-file by double clicking the file...

I checked the association in Windows and the RDP-extension is linked to the Windows Remote Desktop application.

Used code :

hDCScreen = GetDesktopWindow()
? ShellExecute ( hDCScreen, "Open", "c:\Test.rdp","","",0)
