Thanks, Andreas, (and sorry - I accidentally sent my original reply to this
post to your e-mail rather than the forum - so to you this will be a
repeat)...
After following Ben Combee's advice (see Re: Traget Settings for Hack?), I
got my hack working, and in testing it appears to run fine with at least the
pre-installed Palm apps. I am worried, however, about having UI resources
in the hack that could conflict with the calling app. As I want the app to
run on 3.1 and above, dynamically generating UI, as you suggest here for
4.0+, doesn't sound like a valid alternative.
My hack is a modal dialog that loads its resource DB, intializes the form in
question via FrmInitForm, and then takes control of the event loop within
the hack code resource. Once the user finishes with the dialog, the
function erases the form, unloads the DB and returns control to the calling
form/app.
So:
1). Does FrmInitForm look for resources in a particular order (like most
recently opened DB first)? If so, I shouldn't have a problem. If not -
2). Is there another way to intialize a form, where I can specify the
resource DB to use?
3). Is there a range of UI IDs that would be safe (not likely, I would
guess)?
- or -
4). Are there dynamic alternatives for older OSes (keeping in mind that my
form has field, button and gadget resources on it)?
Thanks!
Geoff
