Flora,
A gadget has no visual representation when your app is running unless your
app draws something on it. Under the OS 3.5 New Feature Set, drawing is
normally done within a function you write, FormGadgetHandler(). With
earlier feature sets, this mechanism was not specified (there was no
FormGadgetHandlerType in the FormGadgetHandler structure). Prior to 3.5,
you just draw the gadget whenever you need to (as long as it's *after*
calling FrmDrawForm).
The several posts you have made about the problems you have had capturing
and drawing a bitmap on a gadget lead me to believe that your code for
capturing the bitmap is the problem. Why don't you post that code? Maybe
someone will be able to spot the problem.
