When I execute the following code, I get an error saying:
"ServiceTime just wrote to memory location 0x000026B7, which is in
Memory Manager data structures."
What am I doing wrong?
Thanks,
Todd
**** code starts here ***
DateToDOWDMFormat(gCurrentRecord.start.month,
gCurrentRecord.start.day,gCurrentRecord.start.year,
sysPrefs.longDateFormat,label);
SetFieldTextFromPtr(ServicePeriodStartField, label);
static FieldPtr SetFieldTextFromPtr(UInt16 fieldID, Char* newstrP)
{
MemHandle txtH;
char *str;
// get some space in which to stash the string
txtH = MemHandleNew(StrLen(newstrP + 1));
if (!txtH)
return NULL;
// copy the string to the locked handle
str =MemHandleLock(txtH);
StrCopy(str, newstrP);
// Unlock the string handle
MemHandleUnlock(txtH);
// set the field to the handle
return SetFieldTextFromHandle(fieldID,txtH);
}
static FieldPtr SetFieldTextFromHandle(UInt16 fieldID, MemHandle txtH)
{
MemHandle oldTextH;
FormPtr frm = FrmGetActiveForm();
FieldType *fldP;
// get the field and the field's current text handle
fldP = FrmGetObjectPtr(frm, FrmGetObjectIndex(frm, fieldID));
ErrNonFatalDisplayIf(!fldP, "missing field");
// Retrieve the field's old text handle
oldTextH = FldGetTextHandle(fldP);
// Set the new text handle for the field
FldSetTextHandle(fldP, txtH);
FldDrawField(fldP);
// Free the old text handle to prevent memory leak
if (oldTextH)
MemHandleFree(oldTextH);
return fldP;
}
