Hi Jon,
I have the same function and works perfect. I'm using Codewarrior 6.0 (C
compiler) and PalmOS 3.5, here is my function
/***********************************************************************
*
* FUNCTION: GetObjectPtr
*
* DESCRIPTION: This routine returns a pointer to an object in the current
* form.
*
* PARAMETERS: objectID (in) - The resource ID of the control to get.
*
* RETURNED: Pointer to the control.
*
***********************************************************************/
static ControlType * GetObjectPtr (UInt16 objectID)
{
FormPtr frm;
frm = FrmGetActiveForm ();
if( frm )
return ((ControlType *)(FrmGetObjectPtr (frm, FrmGetObjectIndex (frm,
objectID))));
else
return NULL;
}
