Creating a Class Library
--------------------------------------------------------------------------------

1) Choose File NewProject
2) Select ClassLibrary from the project templetes.
3) Suppose I rename it to ClassLibrary.
4) Add Code inside the block code.
I write
Public Class assembly
Public Function add(ByVal x As Integer, ByVal y As Integer)
Return x + y
End Function
End Class
5) Choose Build-Build ClassLibrary.


RUNNING A DLL FILE—
1)Project-->Add WindowsFormRename it to Yogesh
2) Server Explorer-->Right Click-->Add Reference-->Open the ClassLibrary.
3)Imports Assembly
In the above imports statement, Imports assembly is there or
Imports ClassLibrary is there.

Public Class yogesh
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

End Sub
End Class
I also do not know what to write on the click event of the button.

Dim xyz AS new ClassLibrary.Assembly
xyz.Add(your parameters...)

I am not VB programmer; syntax may be wrong..

You may need Imports ClassLibrary.Assembly

>I also do not know what to write on the click event of the button.
It's kind of hard to tell you what to write when I have no idea what you want the form to do.

adding a function to DLL or Class Libary- Means that one we add the function in DLL,we can call this function on any form.
I want simple addtion function & this fn. can be called on any form by.

Hi Damy Ur Syntax is wrong,
dim obj as new classLibrary.assembly

I don't write VB.NET I just help .net problem I think you got me and solved your problem

I didnt got it yaar,

Let's say it again

1- Right click on the project you want to add the dll to.
2- Add reference then browse your dll
3- In the .cs file you call Add method, imports the class library i.e import [ClassLibraryName]
4- Initiate a object from Add method class then call its add method.

hint: dll is the class library output

I think that's tooo clear to solve your problem or I didn't understand you well.

Public Class assembly
Public Function add(ByVal x As Integer, ByVal y As Integer)
Return x + y
End Function
End Class


Calling Method--Imports ClassLibrary
Public Class Form1

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim obj As New ClassLibrary.assembly
Dim sum As Integer
sum=obj.
End Sub
End Class

Now this is the coding i m writing,See & reply

Is there error?? If yes please tell me what's it, I hope there is not
