When you call CreateProcess, that window should automatically become the
top window. Are you saying that's not happening? Have you tried
creating a STARTUPINFO struct and filling in the wShowWindow element?

No, the error message is right. A process handle is not the same as a
window handle. Indeed, a process need not have any windows at all.

One possibility is to enumerate through all of the top-level windows
using EnumWindows, and for each window call GetWindowThreadProcessId to
find the process ID associated with that window to find the one that
matches your process. Remember that the process ID is not the same as a
process handle; the process ID is the third thing in the tuple
CreateProcess returns.
