Go to your own winform program and realize the configuration of managing remote hosts.

Remote Desktop Core Class Library

The windows system comes with Remote Desktop activex dll, Directory:

c:\Windows\System32\mstscax.dll

This kind of library cannot be called directly using c #. Introduce a tool AxImp. exe

AxImp.exe

https://msdn.microsoft.com/zh-cn/library/8ccdh774(VS.80).aspx

The ActiveX control importer converts the type definition in the COM type library of the ActiveX control into an Windows form control.

Control transformation

Enter the following command in cmd

"c:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin\AxImp.exe" "c:\Windows\System32\mstscax.dll"

You can generate AxMSTSCLib. dll, MSTSCLib. dll

Remote Desktop Connection Core Code

  this.Controls.Add(rdpc);
  rdpc.Dock = DockStyle.Fill;
  rdpc.BringToFront();
}

void rdpc_OnDisconnected(object sender, AxMSTSCLib.IMsTscAxEvents_OnDisconnectedEvent e)
{
  // Handle disconnection
