I have the "about" form loading now. I still need to know how to get a text string (char*) to load and display in a field on a form.

The other attempt was to load an "about" form from a form I had created in PILRIC, then copied "about" form handling procedures from the main form.

No text is displayed. I am using a routine > (SetFieldTextfromStr(field, Trans.s, redraw)) from a copy of Palm OS > Programming, The Developer's Guide to actually undertake acquisition of the object handle and placement of the text in the control, which I hesitate to post given copyright considerations related to the book. > > Thanks to anyone who chooses to respond with some helpful insight. > > -- > For information on using the PalmSource Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/ > -- For information on using the PalmSource Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
