OK the question is you have DLL having language VB.Net
then you want to use that dll in your application which is in C# or vice cersa
YES you can do that as DLL contains IL code which is not language specific

Thanks and Regards

You need to add reference to that dll in c# project. And call the methods as you do like in c#. NET uses common language runtime So it doesn't matter your code is in c# or vb.net

string Cheers = "Navaneeth!!"

Use c# class in vb.net class library

13-Mar-07 21:04

thanks for reply.
I am adding reference in my vb.net class library, reference is showing in reference window but can't give reference in my vb.net class.

imports myC#Namespace

it's missing it rather it is in reference but nothing in that. no namespaces in Dll.

hi,

there is one class library named as VBClassLib made up in Vb.Net.
in this library i have 2 vb.net classes.

and another class library is C#ClassLib made up in C#.Net.
there are 2 classes in this class library.

now i am making Dll of C#ClassLib and giving reference in VBClassLib to use methods of C#ClassLib in VBClassLib.

when giving reference that Dll is showing in VBClassLib's references.

But when i am importing C#ClassLib DLL's namespace in VBClassLib's class,
like Imports C#ClassLib.Method

it's giving error that "namespace or type is in the C#ClassLib.Method doesnpt contain ant public member........."

but it's not so. I have made public class in C#ClassLib.

Thanks,
Sun Rays

Hello Dharmender,

ASP.NET 2.0 has lots to offer (like extensibility and simplicity) as far ASP.NET 1.1 is concerned. Here is the link for a nice article from Jon Flanders which discusses 10 new features in ASP.NET 2005 in detail:

http://www.theserverside.net/tt/articles/showarticle.tss?id=WhatsNewASPNET

Let me know if you are unsure about any new feature in ASP.NET 2005

Hello Alex,

It is always good to encrypt these login details): You can implement this in different ways. Here is a small code snippet which does exactly the same thing using JavaScript:

I have taken a look on this javascript earlier at http://www.webteacher.com/. This is a small example but it should get you started on encrypting these login details.

OK you want the code in C# means encryption at server side
Why you want to Encrypt the value at the server side do you want to store that value in database something like that
Best way is to have own algorithm to encrypt and decrypt the data

d.Decrypt(textenc)
Dim textdec As String = d.Content()
Response.Write(textdec)

Try the above , the value given as string in the function SetSecret is the key I am using , u can use anything. Add a reference to Capicom in ur project and then implement the same
