I Have recently searched the web trying to find answers on how to create and run a MSTSC RDP session in WPF, Finally got all what i needed, created the AxMSTSCLib dll and added that and MSTSCLib dll as a reference into the project. but after creating a user control and adding a windows form host, running the application does not display the MSTSC Active X Control.
If i swap the RDP control to something like a TextBlock it displays so i know it can't be something to do with the user control as such. An event when loading the user control fires and does the below;
private void UserControl_Loaded(object sender, RoutedEventArgs e)
{
try
{
AxMsRdpClient9NotSafeForScripting rdp = new AxMsRdpClient9NotSafeForScripting();
//AxMsTscAxNotSafeForScripting rdp = new AxMsTscAxNotSafeForScripting();
//AxMsRdpClient9 rdp = new AxMsRdpClient9();
rdp.CreateControl();
rdp.AdvancedSettings9.AuthenticationLevel = 2;
rdp.AdvancedSettings9.EnableCredSspSupport = true;
rdp.AdvancedSettings9.NegotiateSecurityLayer = false;
rdp.Server = server;
rdp.UserName = "jwilson-hogg";
rdp.DesktopHeight = 768;
rdp.DesktopWidth = 1024;
rdp.Connect();
RDP_Host.Child = rdp as System.Windows.Forms.Control;
}
catch (Exception ex)
{
MessageBox.Show(ex.Message + "\n\n" + ex.InnerException, "Error Trying to connect to: " + server);
}
}
But nothing actually appears on the application. I have googled and tried to change bits and bobs in the code some errors are thrown but 9 times out of 10 the control does not show the MSTSC session.
UPDATE 1: I have tried moving the rdp.CreateControl() line around incase the control is being created to early, now i am getting the error: "'System.Windows.Forms.AxHost.InvalidActiveXStateException' occurred in AxMSTSCLib.dll"
