Detecting pop up window

[ViperInc]

Hi,

I'm currently trying to write a program which will detect a pop up or new window and print the related co-ordinates to a file. Looking the msdn API i have put together the following code. Being totally inexperienced at C I'm at a loss as how to implement the code below, or even if it will do what I hope.

#include "stdafx.h"
#include "Winuser.h"
#include "Windows.h"

int APIENTRY WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow)
{
//for(!stop) - loop until stopped, maybe with button?

typedef struct coOrd { LONG left;
LONG top;
LONG right;
LONG bottom;
} RECT, *PRECT;

BOOL GetClientRect(HWND GetForegroundWindow(VOID),LPRECT coOrd);
}


now, from what ive gathered, it will create the coOrd structure, and then put the forground co-orinated into it.

how can i access these co-ordinates, and put them into a file. how easy is it to add a go/stop button or add a timer.

i am very un-skilled at c, any help would be greatly appreciated.

thank-you
VPR

I'd say you should work on learning the basics of C++ before trying to do anything using Windows API. That said, here is some code that should do something like what you want to accomplish:

#include <windows.h>
#include <fstream>
using namespace std;

int main()
{
	// Get the window that currently has focus
	HWND hwndInitial = GetForegroundWindow();
	HWND hwndForeground;
	
	// Loop until a new window has focus
	bool bFoundNewWindow = false;
	while(!bFoundNewWindow)
	{
		hwndForeground = GetForegroundWindow();
		if(hwndForeground != hwndInitial)
			bFoundNewWindow = true;
		else
			Sleep(50);
	}

	// Get the rect of the new window
	RECT rc;
	GetWindowRect(hwndForeground, &rc);

	// Write the coordinates to a file
	ofstream file("file.txt");
	file << rc.left << " " << rc.top << " " << rc.right << " " << rc.bottom << endl;
	file.close();

	return 0;
}
