Yeah, Yeah, bang on the VB developer :'( Yes, I know. I do need to drop the VB and move to C at some point, but this app was written in VB so that is what I am going with and what I know (for now). Here are the definitions of the two functions:

 

 

CLng http://msdn2.microsoft.com/en-us/library/ck4c5842.aspx

 

Hex http://msdn2.microsoft.com/en-us/library/8t2d9cx5.aspx

 

 

As for efficiency, you are probably correct. However, if there is any slow down the result is trivial in my case.

 

 

Basically you are correct. The Hex function returns the number as a hex string, then CLng turns it back in to a Long integer (which is a positive number).

 

 

I will keep messing with the code to "optimize" the calculations. If I come up with something better, I will post it. Thanks to both of you for your help..
