Hi Frank/All, I've put a sample program that demonstrates the problems I'm seeing here: http://download.cantabilesoftware.com/VBoxTest.zip.
It's a simple Windows dialog app that hosts a VBox VM using the COM API from the SDK. Error handling is minimal. I've included VS2005 solution/project/source code + x86 and x64 executables. To use it: 1. Copy the appropriate exe to c:\program files\sun\virtualbox (not sure why this is necessary, but not a big issue) 2. Run it 3. Enter the name of a VBox machine with VRDP enabled 4. Click Power Up. 5. Connect to the machine from remote desktop, notice the blank screen. 6. Type something on the keyboard 7. Close remote desktop 8. Click Save State to close the machine. 9. Click Power Up again, notice the error. 10. Close VBoxTest and run up the same machine in the regular Virtual Box front end. Notice keys typed in RD above were received. The issues are: 1. Blank VRDP screen 2. Inability to relaunch the same VM What I'm trying to build is a VBox front end that will host a machine and run it as a Windows system tray Icon. I have few environments where I need to have a number of server type machines running for development purposes and most of the time I just want them out of the way. I'm happy to release this to the community if I can get it working, but I'm not having much luck. I've already tried spawning VBoxHeadless which seems to work fine until shutdown/logoff when Windows just kills it without it or my app having a chance to save it. Any help in resolving these issues would be greatly appreciated.

Right, the VRDPFramebuffer is closed source and actually I'm not sure if you will be able to write a custom frontend which can do RDP. Did you already have a look at VBoxSDL?
