alright, here is the c/lite-c/c++ code that will hide the window from taskbar(also from alt+tab)

Code:
#include <acknex.h>
#include <windows.h>

#define WS_EX_TOOLWINDOW 0x00000080L
void main(){
	wait(1);
	ShowWindow(hWnd, SW_HIDE) ;
	SetWindowLong(hWnd, GWL_EXSTYLE, GetWindowLong(hWnd, GWL_EXSTYLE)  | WS_EX_TOOLWINDOW);
	ShowWindow(hWnd, SW_SHOW) ;
}

obviously this lite-c but you can do this with same method from c++. hWnd is the handle of the Gamestudio window.
