Excel C API roadmap
There is a new SDK for 2010
the C API is still the recommended add-in technology for 2007. If you look here you may get some ideas on issues with C# and Excel http://www.codematic.net/Excel-devel...udio-excel.htm (.net UDFs have poor performance) Cheers Simon Blog: www.smurfonspreadsheets.net johnlon wrote: Incidentally Charles I was just looking on your site entirely by cooincidence!?.

Excel C API roadmap
Personally I would say c# UDFs have appalling performance rather than poor
.... although to be fair it is improving. You can minimise the performance issues (but it will still be slower than VBA and VB6) by - optimising data transfer by assigning ranges to Object arrays rather than processing cell-by-cell - using one of the .Net Excel packages such as Addin Express, Managed XLL or ExcelDNA (free) which use the XLL rather than COM Interop molasses-style interface Charles ___________________________________ The Excel Calculation Site http://www.decisionmodels.com "Simon Murphy" wrote in message ...

Excel C API roadmap
Well, Excel 2010 is still in Beta so its still a work in progress ...
The C API has been extended in Excel 2010 to allow for 64-bit and asynchronous UDFs etc. So the C API has been extended in both XL2007 and 2010: does not sound like its going to go away any time soon.
