Using Classes in VB

[NeilV]

Hello,

I have created a class file in C# and I can use it fine in my C# web pages. However, I cannot seem to get them to work in my VB.Net pages. I am compiling the Class file into a DLL and placing it in the bin directory.
I am trying to use the class in the following way:
Dim Utility() MyUtil = new Utility
I have put the same import staement in both the c# and vb versions.

Any one any ideas?

Neil

Neil - what do you mean by "it is not working"? One thing may be - if you compile and place a C# dll in the bin or a VB.net project, and you are using VS.net, you still need to add a reference to the dll from the VB.net project before you can compile the VB.net project.

Mark,

Sadly I am not using VS.net i'm using WebMatrix which doesn't allow you(I'm not aware of) to reference DLL's.
I have however, got the following line in my aspx page:

<%@ import Namespace=&quot;MyClass&quot; %>

I have created a very simple page using C# to use some of the methods from MyClass and it works fine. So it suggests that there is a syntax error in my VB code. The error message that I get is:

BC30182: Type expected.
Line 18: Dim My as MyClass = new MyClass()

Any ideas?

Well there you go then. VB is not C#.
Try

dim My as new MyClass()

By the way, why not just do the ASP.net page in C#, if that is your preffered language? Mark

Sorry I was half asleep when I said that your VB constructor was wrong. I'm just not used to doing it this way.
But I did manage to get a C# class working in a vb asp.net page using web matrix. At first I got the same error as you (type expected). I think this is because you have created the C# class with a namespace of MyClass. You also need the name of the class itself.

This code works for me

sub page_load(ByVal sender As System.Object, ByVal e As System.EventArgs) handles mybase.load
dim c as new Hello.Class1()
textbox1.text = c.hello
end sub

And all you should have to do is drop the dll into the bin folder - you should not need to set a reference to it.

Hope this helps.

Thanks Mark, that does the job nicely!
