how to call .dll

i'm a beginner on vb.net and i don't know how to call .dll
please help me find the solution

Right click References in solution explorer. Add Reference, and browse to your DLL.

What kind of DLL do you want to call, a DLL that you created, or one of the Windows API DLLs?

it a dll someone create and i want to use it to solve mathematical problem

Did you try what I said?

after you try what mendhak said then you can call your dll by instantiating them.

Perhaps we should also explain to him how to create a dll? :) I think we should...

i think we shouldn't. He already ask how to call a .dll then it implies he already know what he's doing. ;)

Well im curious about how you instantiate a .dll?

instantiating a .dll is just like instantiating a form.

VB Code:

imports mydll <---it is your dll
 
'in your form load
'for example you have a class name walk to your mydll
 
dim w as new walk()
 
w.speed <----your procedure speed under your class walk
