(Question had to have an L... ever other word in the title did :-P) Well, I'm trying to make a little windows hook, and I got the hook working, and all that's fine. But now, I'm having troubles sending a value from my DLL to my Executable. I'll just paste the code, and tell you what's going on: --------------------------
Executable
--------------------------
#include <windows.h>
#include <iostream>

extern "C" __declspec(dllimport) void InstallHook( );
extern "C" __declspec(dllimport) void UnInstallHook( );
extern "C" __declspec(dllimport) void GetX( int *px );
extern "C" __declspec(dllimport) void GetY( int *py );

int main()
{
	int x, y;
	InstallHook(  );

	do
	{
		GetX(&x);
		GetY(&y);
		std::cout << x << '\t' << y << std::endl;
		// Nothing
	}while( (x >= 5) && (y >= 5) ); 

	UnInstallHook();

	return 0;
}




--------------------------
DLL
--------------------------
#include <windows.h>

HHOOK hhk;
HINSTANCE dllInstance;
bool shown;
HWND shell;
HWND button;
RECT startRect;

int x = 10, y = 10;


LRESULT CALLBACK myMouseProc(int code, WPARAM wParam, LPARAM lParam);
extern "C"
{
	__declspec(dllexport) void InstallHook( );
	__declspec(dllexport) void UnInstallHook( );
	__declspec(dllexport) void GetY( int *py );
	__declspec(dllexport) void GetX( int *px );
}



BOOL WINAPI DllMain(HINSTANCE hInstance,DWORD fwdReason, LPVOID lpvReserved)
{
	dllInstance = hInstance;
	shown = true;

	shell = FindWindow(L"Shell_TrayWnd", NULL);
	button = FindWindowEx(shell, NULL, L"button", NULL);

	GetWindowRect(button, &startRect);		// Store the windows's rectangle in this rect.

	return(TRUE); 
}



extern "C" __declspec(dllexport) void InstallHook( )
{
	hhk = SetWindowsHookEx(WH_MOUSE, (HOOKPROC)&myMouseProc, dllInstance , NULL );
}

extern "C" __declspec(dllexport) void UnInstallHook( )
{
	if( !UnhookWindowsHookEx( hhk ) )
		MessageBox(NULL, L"NOT Uninstalled Bitch!", L"Yay!", MB_OK);

}

extern "C" __declspec(dllexport) void GetX( int *px )
{
	*px = x;
}

extern "C" __declspec(dllexport) void GetY( int *py )
{
	*py = y;
}

LRESULT CALLBACK myMouseProc(int code, WPARAM wParam, LPARAM lParam)
{	
	MOUSEHOOKSTRUCT * mouse_hook = (MOUSEHOOKSTRUCT *)(lParam);

	if (code < 0) // do not process message 
		return CallNextHookEx(hhk, code, wParam, lParam); 

	x = (int)mouse_hook->pt.x;
	y = (int)mouse_hook->pt.y;

	if( (x > (startRect.left - 1 ) ) && (x < startRect.right) )
	{
		if ( (y > startRect.top) && (y < startRect.bottom) )
			ShowWindow(button, 0);
	}
	else
		ShowWindow(button, 1);

	return(CallNextHookEx( hhk, code, wParam, lParam ) );

}


Basically, the output is constantly 10, for some reason, so the * = (int)mouse_hook->pt.* isn't working, for some reason. EDIT: sorry for the sloppy code, just trying to get things to work. BTW, this DOES compile (visual studio 2005).

For those interested, I had to create a shared data segment for the DLL, in order to alter the values.

Secondly, I had to change my x and y types to LONGs, since the POINT struct uses LONGs, not ints.

Looks something like this:


#pragma data_seg(".SHARED")
LONG x = 0;
LONG y = 0;
#pragma data_seg()



With linker option:
/section:.SHARED,rws

Works like a charm, now :-)
