How to get Text Width and Height?
Hi, all
How do you get the exact width and height (even if the user has increased or decreased the DPI settings) of a single-font multi-line text without drawing it? Do you use GetCharWidth32 for this process or are there better ways? Could you please demonstrate this process in code please =)

One solution is LOGFONT structure.

i think you can do something like GetDialogBaseUnits and take the hiword and loword of that to get x and y heights and widths of those.
lesee If I remember right:
Code:TEXTMETRIC tm; int xchar,ychar; // to store the values xchar = tm.tmAveCharWidth; ychar = tm.tmAveCharHeight + tm.tmExternalLeading;
There is also
GetTextExtentPoint32(hdc , sBuffer, lstrlen(sBuffer), &Size);
which will use the currently selected font (in the hdc)
Size.cx and Size.cy contain the strings (sBuffer) length and width.
