Run the program and the dock with the existing Delphi 2010 program

Is there a way in Delphi 2010 to launch an application using ShellExecute and then install this application inside another?

those. Program A, written in Delphi, contains 1 form. When the form is shown, program B, written in C #, is launched and fixed on the client in the form of program A?

Yes you can do it. You need to get the window handle of the main form in another process (call EnumWindows). Then call SetParentto make this window a child of your window.
