Title: calling an external Function in VB
Post by: josephjohn100 on June 07, 2004, 04:25:15 pm

I'm calling an external Function from a DLL(written in VC++) from VB.
The function is returning a long value.

I'm calling this function Using a Call function. and trying to get the return values using
if conditions on Err.Number like
   If Err.Number = 0 Then   'like this

But Err.Number is not getting the values if the function returns fail,or cancel value etc.

Is there any other method we can get this value.
I cannot use a
    retval = FunctionName
as in the object browser shows my function as

Sub LogonUser()
    Member of SECURITYLib.Sec    
    Logon a user.

Is there any other method we can get this value.?
