I am trying to store metadata (basically a unique id) along with each cell of a table in a Word document. Currently, for the add-in I'm developing, I am querying the database, and building a table inside the Word document using the data that is retrieved. I want to be able to save any of the user's edits to the document, and persist it back to the database. My initial thought was to store a unique id along with each cell in the table so that I would be able to tell which records to update. I would also like to store some sort of "isChanged" flag within each cell so that I could tell which

I've seen this question: Creating PowerPoint presentations programmatically , but that question asks "Can you?" to which the answer is "yes". But I'm asking "How?" and specifically "From a list of images?" Here's what I do to break a ppt up into images var app = new PowerPoint.Application(); var pres = app.Presentations; var file = pres.Open(input, MsoTriState.msoFalse, MsoTriState.msoFalse, MsoTriState.msoFalse); file.SaveAs(output, Microsoft.Office.Interop.PowerPoint.PpSaveAsFileType.ppSaveAsJPG, MsoTriState.msoTrue); file.Close(); app.Quit(); How do I do the reverse? It'll be something like

I have the whole MS Word file itself saved into a byte array.A want to load it the way I would if it was on file system but with the minimal use of Microsoft.Office.Interop.Word because it is very slow when it gets the the .Open(args[]) part. Try this.... byte[] bte = File.ReadAllBytes("E:\\test.doc"); // Put the Reading file File.WriteAllBytes(@"E:\\test1.doc", bte); // Same contents you will get in byte[] and that will be save here There is no supported way to do it right off-the-bat using Interop.Word , as there are no methods supporting byte arrays. As a viable workaround you can use a

We've had these few lines of code running happily in our applications for several years (and in several versions of Office, 2003, 2007, 2010 etc). Purpose is to perform a kind of a mail merge in a Word document, substituting the field placeholders with names, addresses etc from a database: Dim w As Word.Application Dim d As Microsoft.Office.Interop.Word.Document = Nothing ... Dim f As Microsoft.Office.Interop.Word.Field For Each f In d.Fields f.Select() If fieldName = w.Selection.Text Then f.Result.Text = value End If Next However a user running Office 2013 reports this error on the line f

I'm trying to create an Excel file with C# COM interop but seems it create it by default with 3 sheets instead of empty or only one. What is needed to create it Empty or just with one: Excel.Application xl = null; Excel._Workbook wb = null; // Create a new instance of Excel from scratch xl = new Excel.Application(); xl.Visible = true; wb = (Excel._Workbook)(xl.Workbooks.Add(Missing.Value)); wb.SaveAs(@"C:\a.xls", Excel.XlFileFormat.xlWorkbookNormal, null, null, false, false, Excel.XlSaveAsAccessMode.xlShared, false, false, null, null, null); Take a look at MSDN's explanation of Workbooks.Add

There doesn't seem to much information or any good code samples for setting an Outlook 2007 MailItem's categories programmatically. MSDN has a limited page , and mentions using VB's Split function, saying more or less " you're on your own from here onwards, so sort it out yourself ". So far as I can tell we manipulate the Categories as a comma delimited string property of the mailitem. It seems a bit primitive, is that all there is to it? Does everyone just dig out their library of string functions and parse the Categories property, trusting not to get in a muddle when multiple categories are
