Nobody Can Help With VS2008 Pro Debugger Disabling Step Menus?

Posted: http://forums.asp.net/t/1600590.aspx Repeated: This is a Web Forms Website Project using several Ajax controls I set some break points, then F5, IE loads the .aspx page of the C# source I am trying to debug but then the Solution Explorer opens and adds an item and tree of items labeled Script Documents > Windows Internet Explorer > MyPage.aspx and about a dozen ScriptResource.axd files (including jquery files from a library loaded using absolute referencing which I have commented out in code to determine if jQuery library was causing this wierd behavior). The Debug > Step menu selections are all greyed out and pressing any Function keys does nothing. I also recall script files loaded into IE which "looked" like I was stepping into and over or whatever but that has not been intentionally repeatable.  

ASP.Net Gridview Edit Update Cancel Commands

In ASP.Net 2.0, GridView Control also provides the functionality to edit and update the data retrieved from the database using CommandField template. You can cancel the action using Cancel Command of the CommandField. GridView consists of events that can be used to perform the actions like edit, update and cancel upon the Data items displayed in the ASP.Net GridView Data Control.

Creating Sites/Lists/List Items under Current User Context in SharePoint By Using SPUserToken

Usually we do this by performing the action under RunWithElevatedPrivileges method and updating the listitem using SPListItem.SystemUpdate() method (see here). but this approach has its own flaws like (RunWithElevatedPrivileges will run under system account, we cannot use SystemUpdate for SPSite,SPWeb,SPList, since it runs under system we will "CreatedBy" by as SystemAccount).

Need help with objects and arrays


I have an objuct that I declared like this:

    Class DailyStats
        Dim _day As String
        Dim _hour As String
        Dim _impressions As String
        Dim _clicks As String
        Property Day() As String
                Return _day
            End Get
            Set(ByVal value As String)
                _day = value
            End Set
        End Property
        Property Hour() As String
                Return _hour

How to check for null/empty strings on dynamic objects?


What is the proper way to check for null or empty strings on dynamic objects? This is the only solution I've found so far:

if (admin.PasswordHash.GetType() == typeof(DBNull) || admin.PasswordHash == string.Empty)

If the field is null, the object returned is DBNull.Value, but if the field is empty string, it's return as a System.String object. This makes it impossible to do regular "admin.PasswordHash == DBNull.Value" check, as that will fail whenever the field has been set to empty string. Is my example the right (and only) way to go?

Sending a File Using Email Helper in WebPages/Razor


Note: This is particularly with respect to Email Helper in WebPages/Razor. Please don't post links using System.Net.Mail object.

Following this tutorial: http://www.asp.net/webmatrix/tutorials/9-adding-email-to-your-website

Under "Sending a File Using Email" section what exactly is the code trying to do.

1: The SendFile.cshtml does not have any option to select file.

2: ProcessFile.cshtml is running fine. I am getting the email but no attachement.

I tried changing fileAttachment input to type="file" but not file is being sent to my email. I just get the message send in body.

Question: How exactly this file attachment works using Email Helper in WebPages.

Class which contains an array of objects of type "Class2"



1  Partial Class _Default
2  Inherits System.Web.UI.Page

3 Public Function Ohjoy(ByVal X As Integer) As Integer
4 Dim theClass As New Class1 '= New Class1()
5    theClass.ReSize(0)
6    theClass.myBaby(0).GetName(0) = "Hello" 'Property Chars is read only'
7    Return 1
8 End Function
I have a first class named "Class1". I have a second class named "Class2" Class2, is a member of class 1,
and is implemented as an array of objects of type Class 2.

If I try and call the Accessor GetName() my hard coded value "Hello" in my accessor is not returned? Only
an alpha character like "T"

Also if I try and assigne a value using the setter GetName() it does not work, and the compiler gives me
an error message "property Chars is ReadOnly? Does anyone know what is wrong in my code? Line 6 above


Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
End Sub
End Class

Public Class Class1
    Dim bs As Integer
    Public myBaby() As Class2
    Public myB As Class2
    Public Function ReSize(By
