Hi C++ GURU's I have a question on launching applications within an application

You can use SetParent
let's say you want to do this with calc.exe,
first off we need to get the handle to calc.exe that's runing now.
HWND calc = FindWindow("SciCalc","");
now where did that come from?
SciCalc is the classname to the main window in calc.exe
i got that by opening spy++ (a visual studio tool, or get any APISpy) when you click find window and hold that target icon over calcs window youll see the classname. handles change each time classnames do not change ever.
so now we have the hwnd assuming that calc.exe is running, add code to check if calc == 0
now you need the handle to the window you want to put calc in, lets sya you have that in the "scrollwin" variable
SetParent(calc,scrollwin);
and now calc will move to be inside your scrollwin window as a child, if you minimize scrollwin, calc goes with it and etc.
if you want to be able to set it back, setparent returns the previous parent of the handle you send it, so you can save it to return the window later.
make sure you DO NOT close your program without first closing the calculator. so save the handle, or better yet get it again (if you change the view to scientific or vice-versa the handle changes, watch for these things) then close calc before you close the scroll window or itll error in windows.
