    you can easily write a procedure in vbscript in asp and call it on button click or where ever you want
    checkout below sample for more details

    < html>
    < head>
    < %
    sub vbproc(num1,num2)
    response.write(num1*num2)
    end sub
    %>
    < /head>

    < body>
    < p>You can call a procedure like this:</p>
    < p>Result: < %call vbproc(3,4)%></p>
    < p>Or, like this:</p>
    < p>Result: <%vbproc 3,4%></p>
    < /body>
    < /html>
    //You can call a procedure like this:
    Result: 12
    Or, like this:
    Result: 12

    hope it helps

    I am not sure you are looking for VBScript or VB Code.
    Because you have mentioned about the declaration in examples.

    But you can use or utilize the VBCode in ASP Page by calling the asp dll.


    Set Obj = Server.CreateObject("dllname")
    UserID=Obj.DecryptForASP(encryptedUserID)

    Hi,

    Refer this.. for using try catch in VB

    Private Sub populateCountries(ByVal cmb As ComboBox)
    Try
    Dim dsCountries As DataSet = GetcountryNamesUsingQuery()
    If dsCountries.Tables(0).Rows.Count > 0 Then
    cmb.DataSource = dsCountries.Tables(0).DefaultView
    End If
    cmb.SelectedIndex = -1
    Catch ex As Exception

    End Try
    End Sub



    Hope this give you an idea

    Hai Pramod,
    As the ASP is server side scripting language which allows the programmer to write both the client and server side code in the same page. You can write the classic asp code as well as VB script code in the same page.
    The error can be handled using the Error Number and if the Error Number value is not 0, means there is some error in the page and you can display that error.

    If Err.Number <> 0 Then
    Response.Write (Err.Description)
    Response.End
    End If

    But you need to add the below line of code on the top of every page:

    On Error Resume Next

    Hope it will be helpful to you.
