Regards,
I must confess that knowing to program in Palm has been a really tough
experience for me mostly because of the fact that there aren't much
examples available to learn from (and adding to it that I come from a
Java programming environment where in a matter of seconds you find
tons of examples for everything). I am experimenting with hiding
controls and I am getting an error, I have no idea where to call these
methods from, I have the following code and I am getting a memory
error (The lines of interest are the invoke of CtlHideControl and
FrmHideObject):
static Boolean CapurroFormHandleEvent(EventType* pEvent)
{
Boolean handled = false;
FormType* pForm;
switch (pEvent->eType) {
case frmOpenEvent:
pForm = FrmGetActiveForm();
// CapurroFormInit(pForm);
FrmDrawForm(pForm);
CtlHideControl(GetObjectPtr(PuntajeField));
FrmHideObject(GetObjectPtr(PuntajeLabel),
FrmGetObjectIndex (pForm,
PuntajeLabel));
handled = true;
break;
case ctlSelectEvent:
switch(pEvent->data.ctlSelect.controlID) {
case CalcularBoton:
handled = true;
break;
case RegresarBoton:
FrmGotoForm(MainForm);
handled = true;
break;
default:
break;
}
break;
default:
break;
}
return handled;
}

Hi,
Does anybody has an example of functions that make dissappear form
elements with scrolling actions.
