Question

I have managed to keep Microsoft Word’s track revisions property on. It is working fine.

How do I do the same for MS Excel 2007 and above? Follwing is my code for word (which is working fine) and next is for Excel that I am trying to execute.

1. Word:

   Word.Application app = new Word.Application();
   Word.Document tempDoc = app.Documents.Open(path);
   tempDoc.TrackRevisions = true;
   tempDoc.Protect(typ, ref missing, ref password, ref missing, ref missing);
   

2. Excel:

   Excel.Application ex_APP = new Excel.Application();
   Workbook wrk = ex_APP.Workbooks.Open(path);
   

not able to go past this. When I try doing

wrk.

I don’t get property as trackReviosons.

This is the way I am currently doing it it seems to work really well

using Excel = Microsoft.Office.Interop.Excel;  

Then you get active workbook

//Gets Excel and gets Activeworkbook and worksheet
Excel.Application oXL;
Excel.Workbook oWB;
Excel.Worksheet oSheet;
oXL = (Excel.Application)Marshal.GetActiveObject("Excel.Application"); 
oXL.Visible = true;
oWB = (Excel.Workbook)oXL.ActiveWorkbook; 

docProps = oWB.CustomDocumentProperties
