Yes, it is possible to do this. For some components such as Options/X, we have supplied wrapper functions which enable the methods to be called directly in Excel cells.

In the Excel examples, it is shown in one of them, how to use a number of the available functions within the VBA code. That is, in the Function demo, there are a number of simple VBA wrapper functions that wrap the corresponding Options/X methods. These functions show how to effectively call the Options/X methods directly from within the cells of Excel spreadsheets like the built-in functions, however there are a few points to take into account with this approach:

1. Not all Options/X methods may have wrapper functions written for them. However you should be easily able to extend the wrapper functions as required by checking the existing methods and functions.
2. The true advantages of the Options/X control is more easily obtained by using the methods directly in VBA code instead of only using the function wrappers.
   
   The COM Add-In shows the way to use Options/X more directly within VBA code.
   
   If you wish to create new Excel or Access applications, take a look at the way in which the Options/X control is used within the Excel and Access demos. Full source code for each of them is included in the Demo Applications directories.
