PLEASE DISREGARD THIS AS I FIGURED OUT MY MISTAKE, THANKS!
>>> [EMAIL PROTECTED] 11/15/04 03:25PM >>>
I use a few key global variables in my application. One of which is "Refresh".
I use it at the beginning of each FormEventHandler to determine if there are
fields and/or buttons that need to be initialized from data contained in a
specific record. This worked fine until today and now for some odd reason, one
very important variable "Refresh" is updated in the AppEventLoop function,
specifically by the line "FrmDispatchEvent(&event);"
Here is a code excerpt:
-----------------------------------------------------------------------------------------------------------------------------------------
// some other function]
case 1001:
ActiveChannel = 1;
Refresh = true;
FrmGotoForm(2700);
handled = true;
break;
static Boolean Tune12FormHandleEvent(EventType* pEvent)
{
// initialize local variables here
pForm = FrmGetActiveForm();
if(Refresh == true)
{
RetrieveSliderPositions(ActiveChannel);
recordH = DmGetRecord(OemDB, ActiveFile);
if(recordH == NULL) return DmGetLastErr();
record = MemHandleLock(recordH);
Car = *record;
WriteNumberToField(Car.CH[ActiveChannel].FILTERFREQ, 1003);
Refresh = false;
}
switch (pEvent->eType) {
case frmOpenEvent:
pForm = FrmGetActiveForm();
FrmDrawForm(pForm);
handled = true;
break;
case ctlSelectEvent:
switch (pEvent->data.ctlSelect.controlID)
{
case 1000:
ShowHelp(1400); //
blank help screen
handled = true;
break;
-----------------------------------------------------------------------------------------------------------------------------
When I step thru the debugger, I can see Refresh = TRUE when it's supposed to,
but changes to FALSE when it hits this line...
static void AppEventLoop(void)
{
Err error;
EventType event;
do {
EvtGetEvent(&event, evtWaitForever);
if (SysHandleEvent(&event))
continue;
if (MenuHandleEvent(0, &event, &error))
continue;
if (AppHandleEvent(&event))
continue;
FrmDispatchEvent(&event);
} while (event.eType != appStopEvent);
}
This method works great for me, until today, any help will be MUCH appreciated!
thanks,
~Tony
