Waiting for recalculation in Excel 2007

I have a complex spreadsheet with a formula that takes relatively long to calculate ( it references other sheets ).
My code has a loop that puts values in the input cell and retrieves them from the formula's output.
In Excel 2003 it works fine, but in 2007 it "runs away" from the recalculation, resulting in "old" values being retrieved.
Is there a way to force my code to wait for the recalculation to finish, or is there a function that I can pass the formula to and get the value back ?

Hi Johan.

I would advise you to use UDF or XLL add-ins to always retrieve the actual values from your formulas.

Hi Sergey
Thanks for the reply. Please forgive my ignorance, but what do you mean by "UDF or CLL" add-ins. I could not find a reference to it in the Add-In-Express .NET documentation.

Hi Johan.

The UDF is a User Defined Function. You can develop such functions using the 'COM Excel Add-in Module' new item wizard in Visual Studio.
The XLL is an add-in developed using the XLL technology of Excel. To get the XLL module in your project please use 'ADX XLL Add-in' wizard.
