Read the ActiveCell content in Excel using VSTO

Question

I\'m trying to read the ActiveCell from within an Excel Add-in but not getting very far. Anyone any ideas?

Excel.Window W = this.Application.ActiveWindow as Exce         


        

Answer 1

R.Text.ToString(); will get you the text from the cell

Answer 2

Is this of any use: http://social.msdn.microsoft.com/Forums/en-US/vsto/thread/f21c7cf4-fbfd-4496-a593-781eb751d580

It suggests turning off proxies for debugging purposes, hinting that the error message you are seeing may be masking a lower level COM error.

Answer 3

Do not use Activewindow. modified your code as follows Excel.Range R = this.Application.ActiveCell as Excel.Range; if (R != null) MessageBox.Show(R.Value2);

Note: ActiveCell can be null if user have not chosen a cell in the active sheet.
