I am having a problem tracking down an error discovered
using POSE. This error does not occur on the actual Palm.
I have a Form that has a field that simply displays the User
Name. It's properties: Usable=T, Editable=F, Enable=T. The form has
three fields and two buttons. The event handler has code for opening
the form and responding to the two buttons; that's it; very simple.
I do not have any event handlers that have anything to do with this
field. But POSE apparently taps in this field. And that causes the
error.
So, I tried this without POSE. I open the form, then tap the User
Name field and sure enough the same error is generated. But I cannot
determine why it occurs or how to fix it.
The error reported is: "... line 100, invalid field length...".
I have other fields and none of these exhibit this problem. All
properties on all three fields are the same except that the User Name
field is not editable. Everything else on the form works as it
should.
Any tips on why I might get this error by simply tapping a field with
my pen?
Here is the event handler:
//***********************************************************
static Boolean frmRegEventH(EventPtr event) {
FormPtr form;
FieldPtr fldP;
Word fldIdx;
ControlPtr ctlP;
int handled = 0;
CALLBACK_PROLOGUE
form = FrmGetActiveForm();
switch (event->eType) {
case frmOpenEvent:
FrmDrawForm(form);
if(FrmGetFormId(form) == frmRegister) {
RegFormInit(form);
}
handled = 1;
break;
case ctlSelectEvent:
if (event->data.ctlEnter.controlID == btnRegRegister ) {
// if btnRegRegistered is pressed do something here
handled = 1;
break;
}
if (event->data.ctlEnter.controlID == btnRegOk ) {
// if btnRegOk is pressed return to main form
FrmReturnToForm(frmMain);
handled = 1;
break;
}
break;
}
CALLBACK_EPILOGUE
return handled;
}
