Anybody can help me out about DLL?

[vbforum]

Hi, everybody,

I'm now stuck in the debugging of an application. I hope someone
will help me out. The problem is as follows.

I built a DLL component named "Comp". It contains a class module
named "Mod". My client EXE application includes a class module
named "Client". In "Client", I have the following code:

Public myMod as New Comp.Mod
...........
...........
Public Function Proc (Parameter goes here)
Set myMod=New Comp.Mod (Problem occurs in this line.)
..........
..........
End Function

Each time it runs to the Set statement, it gives me an error
message saying "Class does not support automation or does
not support expected init".
I set the reference to Comp.dll in the EXE application. I run the
EXE application after I start the Comp.dll (It's in a separate project.). I tried to unregister Comp.dll and then register it
again. It still doesn't work. Appreciate any possible solutions.
Thanks.

Hi

You have declared in Public declarations like

Public myMod as New Comp.Mod

there is no need to use Set statement again. You can directly access the methods or functions in myMod.

for eg:

myMod.functionname(your parameters goes here)

A small note to make:

Using
Dim Object as New Class

is not good coding practice. It forces the object to be created the first time it is referenced (Which we won't complain about), but thereafter, VB checks to see if the object has been created on every call to that object. This will slow down your application incredibly.
