I am learning some C# and I wonder if I can create dll fiels to be
used in Excel. I saw others post on DLL and tried out a few things
but was not able to make it work. They are al financial functions.

I did:

Go to Excel and declare the functions and also load them up as a
reference.


BUt it did not work.

any help would be appreciate it.

System info

p4 2 gigz
512 ram
Windows XP
Excel 2000
Visual Studio.NET
Microsoft Developement Environment 2002 V 7.0.9466

Ludwig

Hi Ludwig,

Really the only way to do it is to expose your functions in a COM
Class, then use those from Excel (by adding a reference to that class
and Tools References or using 'Automation Addins'). If you search
the .Net help for "COM Class" (no quotes), you should see a C# example
of both client and server. Once you've built that, search again for
'Automation Addin' and you should find an example of how to use it in
Excel.
