Hi!
I would like to do an overlap window, over my main window (of my
application), with a Progress Bar. Exactly when I push a button of my
application I want show a window, with a Progress bar, during the processing
time.
The first question is: Is it possible to have an overlap window? (I create
my windows by the "CreateWindowEx " command) By which command
Is possible to create a "MessageBox " with a progress bar?
Someone know where can I found some sample like this?
I tried to do that first with the application below, maybe someone can give
a look and suggest me something, thanks!!
