Here are two GPF:


Can anyone help?

Dear Sir,
With a small problem that reproduces your errors is almost impossible to know what is happening. Sorry.
It seems one of the errors is produced when printing a richedit. You could make a simply test with that richedit file and see if the GPF is reproduced constantly.
Sorry for not giving you a better answer.
Regards,

The first one happens in TRichEdit:Print() method, and there is only one
line that can cause a "Divide by Zero" exception:
SetRect( &rect, 0, 0, GetDeviceCaps( hDC, PHYSICALWIDTH ) * 254 /
GetDeviceCaps( hDC, LOGPIXELSX ),
GetDeviceCaps( hDC, PHYSICALHEIGHT ) * 254 /
GetDeviceCaps( hDC, LOGPIXELSY ) );
And it's only possible if:
1) you have no printer at all in your computer.
2) you have a printer which driver is giving 0 for LOGPIXELSX or
LOGPIXELSY (it's almost impossible).
3) you are sending an incorrect value in the second parameter. This
second parameter must be a valid hDC. If it's not passed, then Xailer
uses the current printer DC. So, if you are not sure about it, just
don't send the second parameter (or send NIL).
Regarding the second GPF, it seems you are using some kind of COM
library to send data through serial port. And it seems that this library
has buggy and is causing the GPF.

Então Cassiano,
Após muitas tentativas sem íªxito, nós voltamos para o compilador BCC e aparentemente os erros pararam.

So Cassiano,
After many tries without success, we have returned to the BCC compiler and the errors apparently stopped.
