Hi,
If you are just concerned with writing data into an excel format, you could actually just use FmtFile and format it into a comma separated value (.csv) file. These files are automatically linked to excel, and when you double click the file it will open in excel. If you want to maintain some of the formatting that you see in excel, (i.e., style, colors, fonts) you need to use ActiveX controls to set those properties. I would suggest taking a look at one of the examples that come shipped with CVI that uses Excel. You can open this example up and see how they use the function panel that they created, and you can even use that in your app.
