Hi,
Our app is installed with 100+ customers who print all day long. Several of them are now reporting the error below which often occurs randomly but can end up becoming continuous.
System.ComponentModel.Win32Exception (0x80004005): The operation completed successfully
at System.Drawing.Printing.PrinterSettings.GetHdevmodeInternal(String printer)
at System.Drawing.Printing.PrinterSettings.GetHdevmodeInternal()
at System.Drawing.Printing.PrinterSettings.GetHdevmode(PageSettings pageSettings)
at System.Drawing.Printing.PrintController.OnStartPrint(PrintDocument document, PrintEventArgs e)
at System.Drawing.Printing.StandardPrintController.OnStartPrint(PrintDocument document, PrintEventArgs e)
at System.Drawing.Printing.PrintController.Print(PrintDocument document)
at System.Drawing.Printing.PrintDocument.Print()
at Aspose.Words.Document.Print(PrinterSettings printerSettings, String documentName)
at Aspose.Words.Document.Print(PrinterSettings printerSettings)
We have looked into this for a while and during our investigations we were able get the occasional random error such as this one in our own code.
System.ComponentModel.Win32Exception (0x80004005): The operation completed successfully
at System.Drawing.Printing.PrinterSettings.GetHdevmodeInternal(String printer)
at System.Drawing.Printing.PrinterSettings.GetModeField(ModeField field, Int16 defaultValue, IntPtr modeHandle)
at System.Drawing.Printing.PrinterSettings.get_Collate()
This helped us to find this post:
http://stackoverflow.com/questions/1400783/printdocument-print-results-in-win32exception-the-operation-completed-successful
The post points out (among other things) a bug deep in .NET with:
DllImport("winspool.drv", CharSet=CharSet.Auto, SetLastError=true)
public static extern int DocumentProperties(...);
We have worked around the issue in our code by ignoring the error. Unfortunately the error still occurs in the Aspose Words code.
The post above also points to http://blogs.msdn.com/b/dsui_team/archive/2013/06/24/printing-from-a-windows-service.aspx. This post states “System.Drawing is not supported in a service or web application”. It adds that code should be using the Win32 GDI APIs when printing from a Windows Service.
Is there any alternative way in Aspose.Words to print without going through the System.Drawing code?
With kind regards,
Doug
