How would I check what characters are on the screen buffer?

[Marcos]

Here is what Ive been trying:

bool CBlock::move(int _x, int _y) {
	CHAR_INFO charInfo[80*25];
	COORD bufferSize = { 80, 25 };
	COORD bufferCoord = { 0, 0 };
	SMALL_RECT smallRect;
	if (!ReadConsoleOutput(GetStdHandle(STD_OUTPUT_HANDLE), charInfo, bufferSize, bufferCoord, &smallRect)) {
		MessageBox(0, "ERROR", "ERROR", MB_OK);
	}
	if (charInfo[_x*80+_y].Char.AsciiChar != '#') {
		x = _x;
		y = _y;
		return true;
	}
	else return false;
}

So according to this, if _x and _y on the screen buffer are '#', the fucntion should return false, but it doesnt! what am I doing wrong? this is killing me!

I dont know if this is the problem, but isnt it:

array[wanted y-value * max x-value + wanted x-value]

AKA, switch to:

charInfo[_y * 80 + _x]

Now that I think about it, that does make more sense, but it still doesnt work

lpReadRegion
[in, out] Pointer to a SMALL_RECT structure. On input, the structure members specify the upper-left and lower-right coordinates of the console screen buffer rectangle from which the function is to read. On output, the structure members specify the actual rectangle that was used.
