C# code to Hide toolbars in an excel document

I have a C# Winforms program that opens an excel document with 开发者_运维问答the code below. It works great but what I can not figure out how to do, is to turn off ALL menu's and toolbars.

The excel version I am using right now is 2003... But I will be upgrading to 2010 in the near future. Any ideas?

//top of source...
using Excel = Microsoft.Office.Interop.Excel;

// Code inside a function...

// Get report and display it on the screen.
Excel.Application xlApp;
Excel.Workbook xlWorkBook;
Excel.Worksheet xlWorkSheet;
object misValue = System.Reflection.Missing.Value;
xlApp = new Excel.ApplicationClass();

xlWorkBook = xlApp.Workbooks.Open(strFileName, 0, true, 5, "", "", true,Excel.XlPlatform.xlWindows, "\t", false, false, 0, true, 1, 0);
xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);
xlApp.Visible = true;
xlApp.DisplayFullScreen = true;

 // Display the Document and then Sleep.
System.Threading.Thread.Sleep(timeToShowMilliseconds);

// Close the Excel report 
 xlWorkBook.Close(false, misValue, misValue);
xlApp.Quit();

releaseObject(xlWorkSheet);
releaseObject(xlWorkBook);
releaseObject(xlApp);

I've been looking into your case and i think with Excel.Application you can find the answer.

Apparently what you need to do is something like this:

Excel.Application xlApp;
xlApp.CommandBars("tabName").Controls("File").Enabled = false;

try it and let me know, if it doesnt work we'll figure something out.
