HWND ShowWindow Not Showing

[JohnB]

Ok, so for this game I play I am wanting to use HWND to get a command bar to run commands in game. So I think this game doesn't let you set it to visible or something. But I could still link it with console(ie Type text then it use sendmessage to send text to it then activate the textbox)

Problem is, using SendMessage(hwnd, WM_CHAR, 13, 0); Doesn't actually invoke the enter key on the box for some reason. I was wandering is there a way to simulate a real enter key on it without being able to see it?

My program moves it into my own window but it won't show it because I think the game blocks it from being set to visible.
