You still don't have a bitmap created and selected into the MemoryDc =

before calling GetTextExtent() on it.

Enclosed is a version that work for me on Linux and OS-X. It crashes on =

OS-X if I comment out lines 22 and 23, which select a bitmap into the =

MemoryDC before using it.

I added displaying the bitmap jsut for the heck of it.

Note that you could perhaps create a ScreenDC or something to check your =

text size instead of creating a dummy bitmap.
