How can we display Word/Text Document

[Hasan]

I had tried to open the Word document into the GDPicture .Net viewer, I had got the Error like
"Attempted to read or write protected memory. This is often an indication that other memory is corrupt. "

Can anybody have the solution for this..

Thanks,
Hasan

Hi,

Word is a closed format. Therefore, if you want to display a doc you have to use the Microsoft automation.

here a sample:

Code: Select all

        Dim oWord As New Microsoft.Office.Interop.Word.Application


        oWord.Documents.Open("c:\mydoc.doc", False, True, False)
        oWord.Documents(1).Activate()
        Clipboard.Clear()
        oWord.Documents(1).Select()
        oWord.Selection.CopyAsPicture()
        oWord.Application.Documents(1).Close(False)
        oWord.Quit()

        Call GdViewer1.DisplayFromClipboard()

Kind regards,

Loïc

I used this code in my project and it seems to only get some of the Word document.

Other times I get invalid clipboard operation messages.

Another way is to create a pdf from word

here's c# code (tested with word 2007 / 2010 beta)

Code: Select all

using Outlook = Microsoft.Office.Interop.Outlook;
using WinWord = Microsoft.Office.Interop.Word;

...

                    object file = Listtodo.SelectedItem.ToString();
                    object nullobj = System.Reflection.Missing.Value;
                    object doNotSaveChanges = WinWord.WdSaveOptions.wdDoNotSaveChanges;

                    string paramExportFilePath = @"C:\Test.pdf";
                    WinWord.WdExportFormat paramExportFormat = WinWord.WdExportFormat.wdExportFormatPDF;
                    bool paramOpenAfterExport = false;
                    WinWord.WdExportOptimizeFor paramExportOptimizeFor = WinWord.WdExportOptimizeFor.wdExportOptimizeForPrint;
                    WinWord.WdExportRange paramExportRange = WinWord.WdExportRange.wdExportAllDocument;
                    int paramStartPage = 0;
                    int paramEndPage = 0;
                    WinWord.WdExportItem paramExportItem = WinWord.WdExportItem.wdExportDocumentContent;
                    bool paramIncludeDocProps = true;
                    bool paramKeepIRM = true;
                    WinWord.WdExportCreateBookmarks paramCreateBookmarks = WinWord.WdExportCreateBookmarks.wdExportCreateWordBookmarks;
                    bool paramDocStructureTags = true;
                    bool paramBitmapMissingFonts = true;
                    bool paramUseISO19005_1 = false;



                    WinWord._Application myWinWord = new WinWord.Application();
                    WinWord._Document mydoc = myWinWord.Documents.Open(ref file, ref nullobj, ref nullobj, ref nullobj, ref nullobj,
                                                                                ref nullobj, ref nullobj, ref nullobj, ref nullobj,
                                                                                ref nullobj, ref nullobj, ref nullobj, ref nullobj,
                                                                                ref nullobj, ref nullobj, ref nullobj);
                    mydoc.ExportAsFixedFormat(paramExportFilePath,
                                              paramExportFormat,
                                              paramOpenAfterExport,
                                              paramExportOptimizeFor,
                                              paramExportRange,
                                              paramStartPage,
                                              paramEndPage,
                                              paramExportItem,
                                              paramIncludeDocProps,
                                              paramKeepIRM,
                                              paramCreateBookmarks,
                                              paramDocStructureTags,
                                              paramBitmapMissingFonts,
                                              paramUseISO19005_1,
                                              ref nullobj);

                    mydoc.Close(ref doNotSaveChanges, ref nullobj, ref nullobj);
                    myWinWord.Quit(ref doNotSaveChanges, ref nullobj, ref nullobj);
                    gdViewer1.DisplayFromFile(paramExportFilePath);

this code needs the try/catch/finally stuff ... but works
