I have a winform application (.NET 2.0 C#). From this application, I want to start another process (another winform application) and dock it to my window (or at least make it look like it is docked). So far, I can only find information about docking controls, not windows in separate processes. My first thought is to get the handle of the window and use unmanaged system calls to set the height/width and position of the window to my docking area. But before I got started, I wanted to check to see if any of you good people have done something similar. I have access to the source code of the application I want docked but would rather not make any changes if I can avoid it. I have complete programming control over what will be the parent application. Any advice? Thanks in advance!
