[Help]GetPixel()

Here is my code:

Code:

#include <iostream>
#include <windows.h>
#include "Getasynckeystates.h"
int main()
{
	POINT a;
	while(true)
	{
		HWND hwnd = FindWindow(NULL, NULL);
		HDC hdc = GetDC(hwnd);
		if(GetAsyncKeyState(sh) &1){
		GetCursorPos(&a);
		GetPixel(hdc, a.x, a.y);
		
		Sleep(20);
		}
		
	}
}

My problem is that, idk how i would make it tell me the color. Like i would put cout<<blahblha, but idk what to do. Thanks for ur help.

This is kind of off the top of my head.

GetPixel returns COLORREF btw.

[php]
COLORREF color = GetPixel(...);
BYTE red = GetRValue( (DWORD)color );
cout << red << endl;
[/php]

thanks void,

Code:

#include <iostream>
#include <windows.h>
#include "Getasynckeystates.h"
int main()
{
	POINT a;
	while(true)
	{
		HWND hwnd = FindWindow(NULL, NULL);
		HDC hdc = GetDC(hwnd);
		if(GetAsyncKeyState(sh) &1){
		GetCursorPos(&a);
		COLORREF color = GetPixel(hdc, a.x, a.y);
		BYTE red = GetRValue(color);
		std::cout<<red<<"\n";
		Sleep(20);
		}
		
	}
}

here is my code, it's not sending the value to the console, i am pretty sure i did something wrong, thanks for your help, I really appreciate it.
btw why aren't you a junior coder anymore? you know that purple title below ur name. They should make you it again, you are one of the few people on this forum that help in every thread.

press F11 and go step by step through it and everytime you should check your vars...
