Hello everyone,

I'm trying to draw a legenda on memDC like:

colour square : description | colour square : description |....

since I need to apply an offset, is there a function or something to
calculate the relative length of strings on graphic surface?...
I think a character correspond to certain dot pitch length multiplied
to n-chars of the string...

Thanks
Ciao
Luigi

Take a look at CDC::GetTextExtent CDC::GetOutputTextExtent and similar
ones

Have a look at the GetTextExtentPoint32 API.
