GeneralHelp with OnPaint Pin

Currently, I have this code in my on paint event in a view.

<br />
	CPaintDC dc(this);<br />
<br />
	CPoint originalSize = matrix.GetSize();<br />
	int y, x;<br />
<br />
	for (y = 0; y < size.y; y++)<br />
	{<br />
		for (x = 0; x < size.x; x++)<br />
		{<br />
			dc.SetPixelV(CPoint(x,y), obj.GetColorRef(CPoint(x, y)));<br />
		}<br />
	}<br />
<br />


As you can understand, this is pretty slow with soewhat bigger pictures where for example, tje size is over 1000 x 1000 pixels. A solution, as far as I know, is to use a memory DC. However, I am doing something wrong.

I want to create the memory DC with the following

<br />
	CPaintDC dc(this);<br />
	CDC pdc;<br />
	dc.CreateCompatibleDC(&pdc);<br />
<br />
	CPoint originalSize = matrix.GetSize();<br />
	int y, x;<br />
<br />
	for (y = 0; y < size.y; y++)<br />
	{<br />
		for (x = 0; x < size.x; x++)<br />
		{<br />
			pdc.SetPixelV(CPoint(x,y), obj.GetColorRef(CPoint(x, y)));<br />
		}<br />
	}<br />
<br />
	dc.BitBlt(0, 0, size.x, size.y, ...)	<br />
<br />


However, the first time only a black block was drawn then, when resizing things go wrong (the app crashes), where a colored block should be drawn. What am I doing wrong, and if I am doing it wrong, how should I do it?

LPCTSTR Dutch = TEXT("Double Dutch Smile | :) ");
