Question

Interact with Spreadsheet cells from Excel Addin - C# .NET

Asked by: gerry99

Using Visual Studio tools for Office (2005), I'm trying to develope a C# .NET module that will interact with my C# server which updates live stock quotes.  I can easily interact with my module from Excel, but I have 2 problems:

1) I'd like to create an Excel RTD module in C#, so that I can embed custom formulas into cells, that will be updated in realtime.
2) From an Excel Add-in, I can add my menu to excel, and interact with it, but I cannot write a number into a spreadsheet cell.  Every example I've seen looks like:
         Excel.Range rng = Globals.Sheet1.Range["A1", missing];
         rng.Value2 = "socket state: " + state;
My problem is that I don't know where the Globals static object is defined.  The wizard I used to create an Excel addin created a Globals object that does not contain a Sheet1 variable.  Where is this thing defined? and how can I use it, or is there a better way to poke text into a spreadsheet using an Excel Add-in?

Thanks,
Gerry

Try:

         Excel.Range rng = Globals.Sheets("Sheet1").Range["A1", missing];
         rng.Value = "socket state: " + state;

The Globals object I have does not contain a property Sheets.  Where is the Globals object defined?

This does not work for me.
Excel.Range rng = Globals.Sheets("Sheet1").Range["A1", missing];

Thanks,

Try:

   Excel.Application objApp;
   Excel._Workbook objBook;
   Excel.Workbooks objBooks;
   Excel.Sheets objSheets;
   Excel._Worksheet objSheet;
   Excel.Range range;

   objApp = new Excel.Application();
   objBooks = objApp.Workbooks;
   objBook = objBooks.Add( Missing.Value );
   objSheets = objBook.Worksheets;
   objSheet = (Excel._Worksheet)objSheets.get_Item(1);
   range = objSheet.get_Range("A1", Missing.Value);
   range.Value = "socket state: " + state;

Thanks for your help.  This is what eventually worked for me, it is simular to what you suggested, I found the syntax in an MS forum.  Why they could not post a simple example somewhere I don't know.  The key was using get_Range, and getting the Worksheet cast done correctly.

((Excel.Worksheet)Application.ActiveSheet).get_Range("A3", Type.Missing).Value2 = "Test";
