declaring Excel constants
For a VB6 ActiveX dll I had to declare some xl Constants.
Does it matter which of the following 3 ways you choose? Const xlUp as long = -4162 Const xlUp as Integer = -4162 Const xlUp = -4162 It looks the datatype is Integer but I am not sure. RBS |

It doesn't matter, but declaring as Long is the most efficient. Integers
could cause a problem if you try and load a too large value in them. Long is safe and fully typed. -- HTH Bob Phillips (remove nothere from email address if mailing direct) "RB Smissaert" wrote in message ... For a VB6 ActiveX dll I had to declare some xl Constants.

declaring Excel constants
OK, I thought that was the best option but thanks for making it clear.
Just one thing there is the file XL97CONS.BAS on one of the MS sites and that doesn't set the datatype. Any idea why that is? RBS "Bob Phillips" wrote in message ...

All the Excel constants are declared as Longs (Enums) in the
Excel typelib, so go with As Long. -- Cordially, Chip Pearson Microsoft MVP - Excel Pearson Software Consulting, LLC www.cpearson.com "RB Smissaert" wrote in message ...
