dll from VB for C#

Hi
How can I use VB libraries in C# code? I have library.dll file and after
adding it to references in C# i can see only 4 methods, while after adding
it to VB's references i can see 15 methods.

VB or VB.NET? If this is classic VB, try this. Break binary compatibility and
compile to a new DLL. Then examine in C# and see if you still cannot see the
methods. If so, it has to do with COM interfaces. I am not sure what the
solution is, but that is where I would start to look.

mamin,

Is it possible that the methods you see in VB are static? In C#, you
won't see them on instances, rather, you will see them only when scoped
correctly (VB is more lax about this).

Hope this helps.

mamin,

What is sth?

Also, if you want to create an object in C# dynamically, use the static
CreateInstance class on the Activator class.

What do You mean to "use the static
CreateInstance class on the Activator class"?

He meant:

Activator.CreateInstance(Type type);
I remember i used to create <type> by type name, which you actually
need, but i don't have that source handy now. Anyway, it sould be like:

Type myType = <This stupid function>("Your_type_name");
Object myObject = Activator.CrateInstance(myType);

Something like this... i've used it last time about a year ago, so i
might mix some details, but the idea should be correct.

Hope it helps!

Why wouldn't you do this:

// First, load your dll into an Assembly instance:
1. Assembly myAsm = Assembly.LoadFrom("Your_DLL_Name");

// Second, load all types contained in the dll
2. Type[] alltypes = myAsm.getTypes();

// Just print those types on console to make sure they are reacheable:
3. foreach (Type temp in alltypes)
Console.WriteLine("Fount Type:" + temp.Name);

This way you will see which types(classes) of the dll you can access
from c#.

Type yourType = alltypes[<typeindex>]

Oops, i have to go home now, you can google about how to create an
instance of class by type

Or maybe someone else would help?

Hope it helped a bit
