Hi Friends...
I have already posted a version of my problem in the forum. This time i want
to make it more clear..
I am trying to migrate an application from PalmOS 3.1 to Palm OS 3.5.
Application and code work fine with 3.1 but when i try to debug it using
palm OS 3.5 and CodeWarrior 7 (I have made all the changes required to
compile the code on OS 3.5).
Now when i run the .prc on PalmVx i get the login screen(first form) and
after 2 seconds the application crashes...
And when i debug on the emulator(palmos35-en-ezdbg) i get "Bad chunk header"
error in the code below at
FrmSetFocus(frm, FrmGetObjectIndex(frm,
DataCollectorLoginPasswordFieldField));
I think this has got something to do with the MemHandlelock and unlock.. But
i have no clue as to how to deal with "Bad chunk header" error. And i have
already spent 3 days working on this...
Hope someone can help me with this.
Thanks
Praveen
