hi,
I have to use a common function in all the .aspx.vb files containing a function which returns a string of session and application variables. eg

Function ABC() as string
 dim MyString as string
MyString = Mystring & Session("a")
MyString = Mystring & Session("b")
return Mystring
End Function

i want to put this function in a common file from where i would be able to use this function.

Class File is not supporting session and application variables.

Please get me know the answer
Thanks in advance.

Put the function in a class file and pass the session variables in as arguments:

Public Function abc(byVal valueA as string, byVal valueB as string) as string
 Dim myString as string
 mystring += valueA
 mystring += valueB
 return mystring
End Function

"The one language all programmers understand is profanity."

unfortunatley, your solution doesnt work properly for my problem. actually my problem is as i have to use 7 session variable and 2 application variable in the function ABC. if i will pass each time as 9 parameter then it would be much convenient to put this function in the same .aspx.vb file.

Please give me any other solution if anybody can

Hi,
You can use class files surely to achieve the same. So if you are using vb, you will have a file like class1.vb which will be placed in the app_code folder of the application.

Let me write a code for you to help you clear than giving cryptic codes as answers:)

Three files in the project used below are:
Default.aspx, default.aspx.vb and class1.vb (in app_code folder)

default.aspx - has a button (button1) and a textbox (text1)
default.aspx.vb file will have the following code for page_load and button click

Partial Class _Default
    Inherits System.Web.UI.Page

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        HttpContext.Current.Session("session_a") = "Vincent"
        HttpContext.Current.Session("session_b") = "Thomas"
    End Sub

    Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim seschk As New Class1
        Dim sess_string As String
        sess_string = seschk.abc()
        Text1.Text = sess_string
    End Sub
End Class


While class1.vb, the class file will have the following code.
Imports Microsoft.VisualBasic

Public Class Class1
    Public Function abc() As String
        Dim xStr As String = ""
        xStr = xStr & HttpContext.Current.Session("session_a") & " "
        xStr = xStr & HttpContext.Current.Session("session_b")
        Return xStr
    End Function
End Class

I have set the sesssion variables in the page load of the form itself, however you can set it anywhere in any form.
Dim seschk As New Class1 - this code is required to create an instance of the class created in Class1.vb file. You can use the above code to create as many objects in multiple aspx file and use the functions present in class1.vb

Hope this helps, post back if you need further assistance.
