Reference Controls from Class

hi

I have some code below which I call in my procedure to handle errors. I want to put this into class so that I don't have to keep on pasting this code into every page. Problem is that I cannot reference controls or use "Request" I use the request.servervariables so that i can view detailed error msgs but only from my ip address

Any ideas on how to do this
Private Sub ErrorHandler(ByVal ex As Exception, ByVal strMethod As String)
		pnlError.Visible = True
		pnlGUI.Visible = False
		lblErrorMSG.Text = "<p>An error has occured please try again "
		If Request.ServerVariables("REMOTE_ADDR") = "IP ADRESS" Then
			lblErrorMSG.Text += "Error Description: Problem in """ & strMethod & """:<br /> " & ex.Message
			txtError.Text = txtError.Text & vbCrLf & "StackTrace:" & vbCrLf & ex.StackTrace
			txtError.Text = txtError.Text & vbCrLf & "Method:" & ex.TargetSite.ToString()
			txtError.Text = txtError.Text & vbCrLf & "URL: " & Request.RawUrl
		Else
			txtError.Visible = False
		End If
	End Sub

Open in new window

Hello patelajk,

The second one is the easy part,

HttpContext.Current.Request.ServerVariables()

Will allow you to use that object, in fact any of the objects: server/response/request etc can all be dealt with the same way.

As for the first one, you could pass in a reference to the page object and handle it that way:

Public Sub ErrorHandler(ByRef CallingPage As System.Web.UI.Page, ByVal ex As Exception, ByVal strMethod As String)

Then use CallingPge.pnlError.Visible etc

Called by passing in the relevant object:

MyErrorHandlingClass.ErrorHandler(Me,ex,"Some Method")

Regards,

patelajk,

From the page where you would call it, pass the page in as "Me"  as here:
MyErrorHandlingClass.ErrorHandler(Me,ex,"Some Method")

Thanks for that... but got another problem now

I got this in my class
Public Class ErrorCatching

      Public Shared Sub ErrorHandler(ByRef CallingPage As System.Web.UI.Page, ByVal ex As Exception, ByVal strMethod As String)
            Dim pnlError As Panel = CallingPage.FindControl("pnlError")
            Dim pnlGUI As Panel = CallingPage.FindControl("pnlGUI")
            Dim lblErrorMSG As Label = CallingPage.FindControl("lblErrorMSG")
            Dim txtError As TextBox = CallingPage.FindControl("txtError")

            pnlError.Visible = True
            pnlGUI.Visible = False
end sub

and in my .aspx page
i have
ErrorCatching.ErrorHandler(Me, ex, "GetClientName")

i get an error saying that it can't find the controls i.e. pnlError which is on the .aspx page
