Hi All,

I have a multi-line string need to be drawn in a rectangular area which has fixed-width and variable height. As the string being drawn in the rectangle, if a line's length exceeds the area's width, the exceeding part will be put in to a new line.

What I need is to calculate height of boundary rectangle of text area. How can i do it?

I did check GetTextExtend...() functions of CDC, but they allow to get extent of SINGLE line string only.

Please help me in this regard.

Thanks in Advance.

You can use the CDC::DrawTextEx() function with the DT_CALCRECT flag set in nFormat and the rect you wish to draw to in lpRect.

This will expand the bottom of the rect to fit you multi line string.

Take a look at:
CDC::DrawTextEx()[^]

However IMO the better explination of this function is teh corrasponding win32 function which describes the flags better, found here:
DrawTextEx()[^]
