Calling Class from App_Code using vb

[sck10]

Hello,

I am converting a class in the App_Code folder from c# to vb and am having
problems calling the sub procedure. I have created a Sub called HidePanels
in the class "General". When I try to declare a new object of this type in
my codebehind, I get the error: "Type 'HidePanels' is not defined". Any
help with this would be appreciated. Thanks, sck10

code behind
===========
Protected Sub HidePanelAppCode()

Dim HidePanelsHelper As New HidePanels
HidePanelsHelper (Me.Page)

End Sub
App_Code Class
======================
Imports Microsoft.VisualBasic
Public Class General

Public Shared Sub HidePanels(ByVal MyPage As Page)
For Each MasterCtrl As Control In MyPage.Controls
If TypeOf MasterCtrl Is MasterPage Then
For Each FormCtrl As Control In MasterCtrl.Controls
If TypeOf FormCtrl Is HtmlForm Then
For Each ContentCtrl As Control In FormCtrl.Controls
If TypeOf ContentCtrl Is ContentPlaceHolder Then
For Each ChildCtrl As Control In ContentCtrl.Controls
If TypeOf ChildCtrl Is Panel Then
CType(ChildCtrl, Panel).Visible = False
End If
Next
End If
Next
End If
Next
End If
Next
End Sub

End Class

Hi,

To access Shared (static in C#) function in VB.NET, use format such as
ClassName.SubName; so you need to use:

General.HidePanels(Me.Page)

#Shared Members in Visual Basic
http://msdn2.microsoft.com/en-us/library/4hbsxy95.aspx

Hope this helps. Please feel free to post here if anything is unclear.

Hi Walter,

I removed the "Shared" so that its now "Public Sub HidePanels(ByVal MyPage
As Page)". It's my understanding that I should be able to call this by
using the following in my codebehind:

Protected Sub ClosePanelAppCode()

' Create instance of the class.
Dim HidePanelsHelper As New HidePanels
HidePanels(Me.Page)

End Sub

However, I am still getting the error: Type 'HidePanels' is not defined.
Thanks, sck10...

Shouldn't
General.HidePanels(Me.Page)
be the method call?

Hi,

By removing the "Shared" keyword, it becomes an instance method. So you
need to use <instanceName>.MethodName to call it:

Dim HidePanelsHelper As New HidePanels
HidePanelsHelper.HidePanels(Me.Page)

Hope this helps. Please feel free to post here if anything is unclear.

Oops, sorry for the typo in previous reply, should be:

Dim HidePanelsHelper As New General
HidePanelsHelper.HidePanels(Me.Page)
