How to find the width of a String (in pixels) in WIN32

Question

Can you measure the width of a string more exactly in WIN32 than using the GetTextMetrics function and using tmAveCharWidth*strSize?

Answer 1

Try using GetTextExtentPoint32. That uses the current font for the given device context to measure the width and height of the rendered string in pixels.

Answer 2

Depending on how you are using this, you can use DrawText with DT_CALCRECT specified and it will (its always done it fairly accurately for me) calculate the size of the required rectangle based on the text/font/etc.

Answer 3

I don't know for certain, but it seems that:

RECT r = { 0, 0, 0, 0 };
char str[] = "Whatever";
DrawText(hDC, str, strlen(str), &r, DT_CALCRECT);

might work.
