RDP UseMultiMon in seamless mode

Hi all

We are using AxMsRdpClient6NotSafeForScripting ActiveX control to lanch our application in a remote desktop session.

I have everything working as we want - the application is running in seamless mode (RemoteProgram.RemoteProgramMode = true).

We have 1 problem. We can't get multi monitors to work properley. My code:

# _oRDPClient is a AxMsRdpClient6NotSafeForScripting object on the form
((ISupportInitialize)_oRDPClient).BeginInit();
IMsRdpClientNonScriptable5 sec = (IMsRdpClientNonScriptable5)_oRDPClient.GetOcx();
sec.UseMultimon = true;
sec.DisableConnectionBar = true;
sec.LaunchedViaClientShellInterface = false;
_oRDPClient.RemoteProgram.RemoteProgramMode = true;


With the above, I do have multi monitors working, but I also have the remote server desktop in the background meaning I can't get back to my local desktop.

If I remove the sec.UseMultiMon line, the application launchs, I see my local desktop, but I can't move the application to the second screen.

Is there something which I have missed.

Alternatively, is there a way that I can work out which is the secondary monitor and force the application to launch on that monitor instead of the primary one.

Many thanks.

James
