were you using new line characters or one big string? multi line edits?
(as I think the limits are different. I thought you could put more than 256 chars in an edit.)

Have a look at HDC's (Handle to Device Context)

This is a 'holder' for graphical resources (fonts, bitmaps ect) for a particular device (printer, screen ect).

Can have full control of text and images. Harder than the read only edit but needed for any type of GDI app. Biggest thing is to remeber to put them back exactly the way you found/created them.
