I'm having problems accessing an ActiveX Dll that I wrote from within an ASP Page. It works fine in VB but I get the following error when I call it from and ASP Page. I have spent the last 2 days searching the web for an answer to my problem but to no avail. I have read that it might have something to do with the DLL Registration, but I've shutdown IIS, unregistered the DLL, rebooted my PC, and recompiled & Registered the DLL. This hasn't worked.

Error Type:
CIMCmdSocket (0x800A005B)
Object variable or With block variable not set
/1.asp, line 14

The ASP Code is as follows

Dim x
Set x = Server.CreateObject("CIMCmdSocket.CmdSocket")
x.opensocket(Port) ' SocketNumber is the actual port
Set x = Nothing

If anyone has any suggestions/help I would be most grateful.

Back in the dim dark days long ago I remember getting this error, but I'm afraid I can't remember what caused it. Actually it is now coming back. The problem may be a type mismatch between the DLL and the ASP page. ASP is a weakly typed language ie all data is variant, VB is a strongly typed language. Try explicitly converting the value of Port into the datatype VB is going to receive it as eg:
x.opensocket(CInt(Port))

Alternatively, change the type of the Port parameter in the function/sub to Variant. One other way to test things is to change the function so that it doesn't take a parameter and (for the short term) hard code the value into the function.

It's a while since I worked with this stuff so this may not be the problem.

I think you need to check the datatype and direction of your parameters in the DLL. If you're using out parameters (ByRef), make sure you set their type to Variant. Then do some proper casting inside the method to the type you expect.

for more info.

If this doesn't help, post some of the code from the VB method.

Everyone is unique, except for me.

Thanks for your replies.

I eventually got it to work but am confused as to why it never worked in the first place. My code is still exactly the same. It must have been something with the DLL registration!!! 3 days later and still none the wiser! But at least it works!

may i know how it works... since i am also facing the same problem

You might want to start a new post, and also better describe the problem you are facing.
