help in calling a function in ASP.Net Project

[patelcj]

I have a function call declared in .aspx file that I call from the page_load event and it works fine. But when I move the function call to a Module file, it is not able to find it? The error message that I am getting is function name not declared. How do I call that function from my Page_load event. Please help.

I am new to ASP.NET so you will have to bear with me.

Is your function private or public.
I presume is is not a class module.

[patelcj]

I have created a ASP.net web application project and added a module file in the project. The function is public.

I was thinking today and was wondering if you need an imports statement at the beginning of you aspx code.

imports modulename

This is a bit of a stab in the dark.

I understand about classes and can add them so they work, and they are meant to be more difficult than straight modules.

Ah well.

If it is a Class file (.vb) then you can just do this

'Functions is the name of your file (Functions.vb)
Dim f As New Functions
Dim strName As String
 
strName = f.<functionName>(strName)

Still It does not work. Here is the code I am using.

In the Page_load event of the .aspx file I am using the following code:

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'Put user code to initialize the page here



' And return the datatable wrapped in a dataview

lbExams.DataSource = DataLoad()
lbExams.DataTextField = "ExamName"
DataBind()

End Sub


DataLoad is a Public function in Exam.vb module file. Here is the code in the Exam.vb file.



Module Exam
Public Function DataLoad() As System.Collections.ICollection
Dim dt As DataTable = New DataTable
Dim dv As DataView
Dim dr As DataRow

' Add two columns to the DataTable
dt.Columns.Add(New DataColumn("ExamNumber", GetType(String)))
dt.Columns.Add(New DataColumn("ExamName", GetType(String)))

' Put some data in
dr = dt.NewRow()
dr(0) = "305"
dr(1) = "Web Applications With VB.NET"
dt.Rows.Add(dr)

dr = dt.NewRow()
dr(0) = "306"
dr(1) = "Windows Applications With VB.NET"
dt.Rows.Add(dr)

dr = dt.NewRow()
dr(0) = "310"
dr(1) = "XML With VB.NET"
dt.Rows.Add(dr)

dr = dt.NewRow()
dr(0) = "315"
dr(1) = "Web Applications With Visual C# .NET"
dt.Rows.Add(dr)

dr = dt.NewRow()
dr(0) = "316"
dr(1) = "Windows Applications With Visual C# .NET"
dt.Rows.Add(dr)

dr = dt.NewRow()
dr(0) = "320"
dr(1) = "XML With Visual C# .NET"
dt.Rows.Add(dr)

' And return the datatable wrapped in a dataview
dv = New DataView(dt)
Return dv

End Function


End Module

try something like this

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
   Dim dl As clsDataLoad
 
   lbExams.DataSource = dl.DataLoad()
   lbExams.DataTextField = "ExamName"
   lbExams.DataBind()
 
End Sub
 
Public Class clsDataLoad
 
   'Place function code here
 
End Class

I don't understand your problem. Why not just put this at the top of your web page's .vb file..

Imports NameOfSomeModuleYouMade

And stick this anywhere within that .vb file you need to call it.

Dim myModule As NameOfSomeModuleYouMade
myModule.CallMyFunction

If you need to call it from the front side (Aspx), make a Protected function inside your web page's .vb file that instantiates the class and calls the function.

Protected Sub GoCallMyFunction
Dim myModule As NameOfSomeModuleYouMade
myModule.CallMyFunction
End Sub

I am lost for suggestions now.

I created a new web application.
Added a module.
In the module I added a simple function so the module looked like this.

Module Module1
 
    Public Function giveit() As String
        Return "something"
    End Function
 
End Module

I added a textbox to the webform and added this code in the page_load event.

TextBox1.Text = giveit()

When I run the application it worked fine.

Sometimes it helps to go back to basics. But I am not sure in your case.

Did you add a new module to the web application or did you add an existing module you had previously written, say in VB6?
I think as modules go they will be different. A module in a webapp has

Module Module1
...
...
End Module

This is really all I can think of.
