Welll...obvious first....did you initialize the scanner (yes if your
using a laser scanner and you see the laser beam).
Did you check your parens in your switch statements? Sometimes those
buggers get me.
On App Start:
if (ScanIsPalmSymbolUnit())
{
error = (Err) ScanOpenDecoder(); // open the scan manager library
if (!error)
{
bOpenDecoderOK = true; // set global variable that all is well
ScanCmdScanEnable(); // Enable scanning
}
else
FrmAlert( alrtScannerProblem );
}
Put some debug code in at the top of your switch and emulate a
ScanEvent. Then step through your code.
Best of luck!
