This just keeps on getting more strange...
i make this call:
frmP = FrmGetFormPtr(NewCustomerForm);
where frmP is a FormPtr
I call this in the event handler for NewCustomerForm.
the emulator crashes as soon as it comes to this line, inside the event handler!
the call should just return NULL if the form is not open!
Does anyone have an idea?
Aaron?? I am a relative newbie and you said you'd help newbies. :) Please?!

The form sure appears to be the active form, to me. I'm calling this fuction
(getObjectPtr) when I press a button that's on the same form.
I am sure FrmGetActiveForm is not returning NULL. I can examine the values of the
FieldPtr using CodeWarrior's watch capability. The Field value in this FieldPtr is
form 1300, and object 1302 is on form 1300.

Perhaps the form with the field isn't the active form at the time you make
your call -- if that was the case, then FrmGetObjectIndex would give an
error because it wouldn't find the object ID.
You could even be calling this before a form has been displayed, when no
form is active -- make sure FrmGetActiveForm isn't returning NULL.

This is related to my earlier post. I believe it's not a database issue but
something funky with the forms.
I'm having trouble getting the field pointer, and for no apparaent reason. I
have this cookbook function, from the Palm Programming book:
/* begin */
static VoidPtr GetObjectPtr(Word objectID)
{
FormPtr frmP;
VoidPtr fieldP;
Word index;
frmP = FrmGetActiveForm();
index = FrmGetObjectIndex(frmP, objectID); // the error is here
fieldP = (FrmGetObjectPtr(frmP, index));
return fieldP;
}
/* end */
the only difference is it's broken apart so I can watch the variables change
without stepping into the functions that change them.
so I pass an object ID into the form (ID 1302). It's passed in as a
constant.
the form Pointer returned by FormGetActiveForm is the proper form, form
1300.
1302 is the ID for a text field.
The error message that occurs at FrmGetObjectIndex(frmP, objectID) is:
"Application" 1.0 reports "WindowNew.c, Line 3112, Bad window". If this is
the lastest.....
Does anyone have any idea what may be going on?
I'm using the ROM 3.0 debug image on 3.0a7
