Can you more explain?

Well, try something like:

<br />
rect.OffsetRect(0, pDC->DrawText("Test", rect, DT_LEFT | DT_TOP | DT_SINGELINE));<br />

Or simply make your string contain all the lines separated with \n -s and draw them with one call to DrawText.

DT_WORDBREAK, and don't use DT_SINGLELINE with it. But you should read the documentation[^] before asking questions here.

I still don't quite get what you want, what do you mean by "get data from column"? You want to know the size needed to display all the text in a given row and column? Use either GetTextExtent or DrawText with DT_CALCRECT, look these up in the docs.
To draw a bitmap you will need to make a memory DC, select the bitmap into it and then use BitBlt to render it onto whatever you want to render it onto.
So something like this:

CDC MemDC;
MemDC.CreateCompatibleDC(&your_target_dc);
CBitmap *OrigBitmap = MemDC.SelectObject(&the_bitmap_you_want_to_display);
your_target_dc.BitBlt(0, 0, bitmap_width, bitmap_height, &MemDC, 0, 0, SRCCOPY);
MemDC.SelectObject(OrigBitmap);

But you can find this also in the documentations all around the net, Google is your friend.

If you'd read the documentation you'd know that DT_CALCRECT won't actually display the text but only measure its extent.

Use CDC::StretchBlt[^], but be carefull with that because it seems not all printer drivers support it.
