Hi, I am a beginner at creating Excel Add-ins using C++. I
recently read about the asynchronous UDFs and i wanted to try it. I used the codes given at the MSDN
regarding "Writing Asynchronous User-Defined Functions in Excel 2010" and used Excel2010
SDKs, the project was built successfully. I added the xll as Add-in in my excel sheet but when I tried to fetch the UDFs XllEcho or XllEchoA, they were not present there.
Also, i made one simple project using Excel2007 SDKs and it worked properly but same project didn't work with Excel2010 SDKs.
What am I doing wrong? Is there any other way to do that?
