VB COM, Public Method in a class calling a private method in same class yields ByRef error

Public Method in a class calling a private method in same class yields ByRef error

Author	Message
Bob Hanse #1 / 4	Public Method in a class calling a private method in same class yields ByRef error OK, I have some code in a public method calling a private worker method all in a public multiuse class of an ActiveX DLL project. The problem is that it wont compile because I get this error... Compile Error ByRef argument type mismatch The code in the public method calls the private method like this... Dim part1, part2 As Long ... SplitZip part1, part2, entireZipCode And the function signature for the private method is as so. Private Function FormatZip(ByVal part1 As Long, ByVal part2 As Long) As String ... End Function The types are the exact same! Why is VB throwing this error! Thanks for any help. Regards, Bob Hansen

sszele #2 / 4	Public Method in a class calling a private method in same class yields ByRef error part1 may not be what you think. By doing a Dim the way you did part1 may be a variant not a long if you set a break point on the the splitsip function then hold the mouse pointer over part1 you will see the popup and it will contain the word empty. Subsequently if you do the same to part2 it will contain 0. Also what are you doing between the Splitz and the FormatZip function?

Bob Hanse #3 / 4	Public Method in a class calling a private method in same class yields ByRef error Thank you, that worked. Why does it convert that parameter to a variant? I thought you could do multiple declarations in VB like that. Cheers, Bob Hansen Quote: > part1 may not be what you think.

Dale Roberson (Microso #4 / 4	Public Method in a class calling a private method in same class yields ByRef error Nope, VB does not support that type of declaration. At least not in this version. <g> VB.NET will. Thank You, Dale Roberson Microsoft Developer Support
