Im getting this error on my website
Message: Showing a modal dialog box or form when the application is not running in UserInteractive mode is not a valid operation. Specify the ServiceNotification or DefaultDesktopOnly style to display a notification from a service application.
I tried implementing some sample code: i found in the documentation here is the code, I get the above error when I try it off my webserver, I understand it can anyone help me with this.
here is my code.
the main change I did was I changed PrintDialog()

to Windows.Forms.PrintDialog()
because I have nothing that defines PrintDialog(), ( perhaps here lies the problem)

Dim printDlg As Windows.Forms.PrintDialog = New Windows.Forms.PrintDialog()

' Initialize the Print Dialog with the number of pages in he document.
printDlg.AllowSomePages = True
printDlg.PrinterSettings.MinimumPage = 1
printDlg.PrinterSettings.MaximumPage = docWord.PageCount
printDlg.PrinterSettings.FromPage = 1
printDlg.PrinterSettings.ToPage = docWord.PageCount
'Dim owner As Windows.Forms.IWin32Window
If (Not printDlg.ShowDialog().Equals(Windows.Forms.DialogResult.OK)) Then
    Return
End If
Dim awPrintDoc As AsposeWordsPrintDocument = New AsposeWordsPrintDocument(docWord)
awPrintDoc.PrinterSettings = printDlg.PrinterSettings
Dim previewDlg As Windows.Forms.PrintPreviewDialog = New Windows.Forms.PrintPreviewDialog()

' Pass the Aspose.Words' print document to the Print Preview dialog.
previewDlg.Document = awPrintDoc

' Specify additional parameters of the Print Preview dialog.
previewDlg.ShowInTaskbar = True
previewDlg.MinimizeBox = True
previewDlg.PrintPreviewControl.Zoom = 1
previewDlg.Document.DocumentName = docWord.Document.ToString()
'previewDlg.WindowState = FormWindowState.Maximized
previewDlg.WindowState = Windows.Forms.FormWindowState.Maximized

' Show appropriately configured Print Preview dialog.
previewDlg.ShowDialog()

Hi

Thanks for your request. This code will work only in windows application. In Web application you can only print document on server side using Aspose.Words. you can use code like the following:

Document doc = new Document(@"C:\Temp\test.doc");
PrinterSettings printerSettings = new PrinterSettings();
printerSettings.PrinterName = @"hp LaserJet 1010 Series Driver";
doc.Print(printerSettings);

Note, printer should be installed and configured on server side.
Best regards.
