Open an application inside a TForm at a predefined position (Views: 20)


Problem/Question/Abstract:

How do I open an executable in a determined form's area? Example: Open an executable and show it on the left forms part with a size of 400 x 300.

Answer:

This works for me. Keep in mind that some apps have their startup settings set somewhere which may override the Startup structure you pass.

procedure TForm1.Button1Click(Sender: TObject);
var
  StartupInfo: TStartupInfo;
  ProcessInfo: TProcessInformation;
begin
  FillChar(StartupInfo, Sizeof(StartupInfo), #0);
  StartupInfo.cb := Sizeof(StartupInfo);
  StartupInfo.dwFlags := STARTF_USEPOSITION or STARTF_USESIZE;
  StartupInfo.wShowWindow := SW_SHOWNORMAL;
  StartupInfo.dwX := Left;
  StartupInfo.dwY := Top;
  StartupInfo.dwXSize := 400;
  StartupInfo.dwYSize := 300;
  CreateProcess(nil, 'yourapp.exe', nil, nil, false, CREATE_NEW_CONSOLE or
    NORMAL_PRIORITY_CLASS, nil, nil, StartupInfo, ProcessInfo);
end;
