John,

The OCX should either have a help file or a .h file with the constants. You could create a VFP format .h file and just include it. In VB if the constant is &H1234 you'd change it to 0x1234 everything else ought to be ok.

Forms and classes have an Include File menu option to allow you to set the file so all methods can see the #define constants.

On my website in the spyin.zip file it has some sample .h files.

>I am working with an OCX that has examples in VB. Within the examples, they rely heavily on Constants for values. I presume that the OCX has a suite of constants built in. the help screen contains a list of constants vs value vs descriptions.
