Hi,
I'm trying to develop a program in c# which suppose to create new invisible desktop and there spawn mstsc.exe with configuration file in order to connect to remote internet explorer which ive published from windows machine using remoteapp.

when i spawn the mstsc in my original desktop it works fine and it connects to the internet explorer but when i spawn this programatically in the new desktop it spawn the mstsc process but stay stuck on connecting to <machine name> and i cant interact with the remoteapp.

my flow:
1. createdesktop
2. ConvertStringSecurityDescriptorToSecurityDescriptor - low integrity level
3. GetSecurityDescriptorSacl
4. SetSecurityInfo - to the new desktop handle
5. create explorer process on the new desktop
6. setthreaddesktop to the new desktop handle
7. create process "mstsc <conf file>" in the new desktop

what im missing?
why my new desktop doesn't work like my original desktop?
why when im running explorer in my new desktop i dont see the wallpaper and my user desktop? in only see the file explorer


thanks.

Well, the only difference I'm seeing is that your hidden desktop is... hidden. Obviously, MS made sure that RDP would run only on active desktops.

even if i switch to this desktop using SwitchDesktop() the mstsc still stuck. so the problem is not the hidden desktop. i think that im missing something in the preparation of the new desktop but cant figure out what missing.

even if i switch to this desktop using SwitchDesktop() the mstsc still stuck

This is after you created it in hidden desktop? what if you create desktop switch to it and launch mstsc?

tried this still the mstsc dont connect successfully. it show only black screen and the title is "connectig to <pc name>"

I can't a difference between this and connecting to machine normally. I think you don't launch mstsc propertly.

Since you haven't posted your code it is pure guessing on our part. Have you tried filling in STARTUPINFO.lpDesktop when launching mstsc in the new desktop?

I'm using this library: www.codeproject.com/Articles/7666/Desktop-Switching for desktop creation and for process spawning.
this library have createprocess method which already sets the lpDesktop to the new desktop so i dont think that this is the problem.
