Exception invoking CreateSaveDC Method
|

Hello,
<br>
I'm trying, by following the samples at www.eprintdriver.com to code a simple program than uses one existing Task Printer at ePrint 5 in order to convert a DOC file in a PDF File. The code seems to be simple:
<br><br>
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click<br>
Dim DeviceSetting As New EpnDeviceSettings<br>
Dim MultiSaveOptions As New pnMultiSaveOptions<br>
Dim ExtraDcOptions As New EpnExtraDcOptions<br>
Dim PrinterList As New EpnPrinterList<br>
Dim hDC As Long<br><br>
If SetupEPrintInstance() Then<br>
ePrintInterface.GetPrinterSaveOptions("TIFPrinter", MultiSaveOptions)<br>
hDC = ePrintInterface.CreateSaveDC("PDFPrinter", DeviceSetting, MultiSaveOptions.PrinterSaveOptions(0), ExtraDcOptions)<br>
ePrintInterface.StartDoc(hDC, "c:\sgd\nas\Prueba.doc")<br>
ePrintInterface.EndDoc(hDC)<br>
ePrintInterface.DeleteDC(hDC)<br>
End If<br>
End Sub<br><br><br>
But, when debugging, at the moment i call the CreateSaveDC Method, i get the following error:<br><br>
Exception from HRESULT: 0x800A4E2D<br><br>
The "curious thing" here is that, before this call, the content at ultiSaveOptions.PrinterSaveOptions(0) and at every array element are the same ("Exception from HRESULT: 0x800A4E2D").<br><br>
What does it happen? Should have this anything to do with the fact of using an existing printer? Why does it fail whenever invocating the printing through this printer through native application (MS Word) work?<br><br>
The environment is Windows 2003 Server and the programming language is Visual Basic .NET under Visual Studio 2005 with .NET Framework 2.0<br><br>
Thank you very much
