Alright I made it finally. I still got problem with the timing, makes my puter very slow... I'll work for it later...
Here's the code -
//Globals
int sX, sY, x, y;
BYTE* sData = 0;
POINT cursorPos;
HDC hScreen;
HDC hdcMem;
HBITMAP hBitmap;
HGDIOBJ hOld;
void PixelFunction(); // Get the pixel rgb function
int main()
{
PixelFunction();
ReleaseDC(NULL, hScreen);
DeleteDC(hdcMem);
return 0;
}
void PixelFunction()
{
int Red, Green, Blue;
hScreen = GetDC(NULL);
sX = GetDeviceCaps(hScreen, HORZRES);
sY = GetDeviceCaps(hScreen, VERTRES);
hdcMem = CreateCompatibleDC (hScreen);
hBitmap = CreateCompatibleBitmap(hScreen, sX, sY);
BITMAPINFOHEADER bm = {0};
bm.biSize = sizeof(BITMAPINFOHEADER);
bm.biPlanes = 1;
bm.biBitCount = 32;
bm.biWidth = sX;
bm.biHeight = -sY;
bm.biCompression = BI_RGB;
bm.biSizeImage = 0; // 3 * sX * sY;
while (1) {
hOld = SelectObject(hdcMem, hBitmap);
BitBlt(hdcMem, 0, 0, sX, sY, hScreen, 0, 0, SRCCOPY);
SelectObject(hdcMem, hOld);
free(sData);
sData = (BYTE*)malloc(4 * sX * sY);
GetDIBits(hdcMem, hBitmap, 0, sY, sData, (BITMAPINFO*)&bm, DIB_RGB_COLORS);
GetCursorPos(&cursorPos);
x = cursorPos.x;
y = cursorPos.y;
Red = sData[4 * ( (y * sX) + x) +2];
Green = sData[4 * ( ( y * sX) + x) +1];
Blue = sData[4 * ( (y * sX) + x)];
// Check for color
if (Red == 255 && Green == 0 && Blue == 0) {
mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0);
Sleep(5);
mouse_event(MOUSEEVENTF_LEFTUP, 0, 0, 0, 0);
}
Sleep(10);
}
}
Hope it helped!
