Using a dll with my web form

Sep 03, 2009 11:12 PM|LINK

Hello

I'm pretty new to dot net and I'm stumped. I've created a nice little dll written in vb.net called cybersource.dll that interacts with the CybersourceWS dll. It has a bunch of properties and methods I use to make transactions. I also have a web form called reservations.aspx that has a code behind file called resevations.aspx.vb. The from is pretty standard stuff to collect the credit card billing info.

I've complied and copied my cybersource.dll and cybersource.xml and just for good measure the CybersourceWS.dll to the same folder as the reservations.asp and reservations.aspx.vb.

It would be really swell if someone could explain to me, a noob, how to call this dll from my aspx.vb page so I can use the methods and properties, but I can't figure out how.

How is this done? And please in detail I'm a noob.

Regards

WebRuss

Drop your DLL's into the bin folder. .NET looks for DLL's in the Bin folder, followed by the GAC (Global Assembly Cache).

Also, a web application wouldn't require the *.aspx.vb files, while a web site does require *.aspx.vb (just a FYI)

Thanks for your reply. I will give it a try. One more bit of info I need. How do I acutally reference my dll in my aspx.vb file? do I use imports ? do I use system.create()?

Yes this is a web site I guess. I hand wrote these pages in notepad++ to interact with my dll.

If ur dll is written in .net then u can directly add reference to ur project of the dll that u need to use in ur application.

If ur dll is written in some other language then refer following links:

Thaks for all your replies! I am sooooo close here...

I copied

Interop.CybersourceWSLib.dll

cybersource.xml

cybersource.pdb

cybersource.dll

to the BIN folder on the website.

Then in my aspx.vb file I did the following:
```
Imports cybersource
Partial Class registration
    Inherits System.Web.UI.Page
    Private Shared objCyb As cybersource.Cybersource
```
That seems to work OK - well at least no error are generated.

Now further down in my class I get an error
```
Protected Sub btnSubmit_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnSubmit.Click
        
        Dim ObjCyb as New cybersource Object
```
Compiler Error Message: BC30205: End of statement expected.

On the above line.

What am I dong wrong?
