Hello,
im able to Convert a Doc file to PDF.
But the Way i am doing it is very slow, which makes it nearly unusable.
Im doing it the following way:
wordDocument = appWord.Documents.Open(path, ReadOnly: false, Visible: false);
wordDocument.ExportAsFixedFormat(System.IO.Path.ChangeExtension(path, ".PDF"), WdExportFormat.wdExportFormatPDF, false, WdExportOptimizeFor.wdExportOptimizeForOnScreen,
WdExportRange.wdExportAllDocument, 1, 1, WdExportItem.wdExportDocumentContent, true, true,
WdExportCreateBookmarks.wdExportCreateHeadingBookmarks, true, true, false, ref oMissing);
wordDocument.Close(SaveChanges: false);
