Error handling win WPDFPrinter

1. offizieller Beitrag

    How can I handle errors in WPDFPrinter?

    TWPPDFPrinter *WPPDFPrinter1;
    .
    .
    .

    WPPDFPrinter1->Filename = sPDF_FileName;
    WPPDFPrinter1->BeginDoc();
    .
    .
    .


    The path in sPDF_FileName points to a device which is not available, e.g. a USB-Stick which is not plugged in. In the debugger I get an exception in the WPF-dll, but I have to know what happened and if creating the file was successfull.

    Thanks in advance!

    In this case the BeginDoc procedure will also create an exception and set the variable LastError to 1.

    OK, I found that, it is working, thank you!

    But I do the creating of PDF in a COM-Server, and there I always get the LastError-Variable with 0!

    WPPDFPrinter1->BeginDoc();
    iPDFError = WPPDFPrinter1->LastError;

    if (iPDFError == 0)
    {
    ...
    }
    else
    {
    return -1;
    }
