I have written a signature capture mini-app for tablet PCs. The way this
works is that our main application calls this little app with a command line
arg of the jpg name to save the signature to. The app consists entirely of a
single form with an ink gathering control and 2 buttons so the user can
cancel or save the signature.
We need this little signature app to be on top of everything at all times.
The client has specified that the user should not be able to do anything at
all until they have either hit the 'Done' button or the 'Cancel' button.
What's the best way to accomplish this? I can think of a few different ways
to do it, but I'm unsure what the recommended way is.
