Posted: Tue Aug 10, 2010 2:57 pm Post subject: Using Licensing with Excel VBA |
|
|
I have an Excel sheet with VBA macros that I would like to apply a license to.
I imagine I would need to design a new .NET .dll wrapper that exposes the infralution.licensing.dll parameters for COM interop, and then reference that .dll from Excel.
Has anybody had any experience doing this, or any suggestions or comments?
Thanks! |

Sorry - I missed this post somehow. While you could use ILS like this to license and Excel sheet it would be vulnerable to someone spoofing the COM interface (since unlike .NET references there is no strong name checking of COM interfaces). If you could put some of your application functionality into a .NET assembly (which used ILS for the licensing) this would make your application much less vulnerable to cracking. _________________ Infralution Support |
