Updating Child Collection Of POCO (adding/updating/deleting) In Entity Framework 4.1?

Jan 25, 2012

I have a webpage with a form that is used to edit some object. This object contains a Collection of other objects defined like this: Public Overridable Property Employees As List(Of Employee)

On a form I can delete an employee, add a new one or modify existing one. When I click save new values are sent to the server. On a server I check if the user exists. If exists then I modify its values, if it does not exist then I add it. All employees that exist on the server and were not sent are marked as deleted (State changed to EntityState.Deleted). I try to use the following code (dbCollection = database entities, newCollection = collection sent from the form):

[Code]...

This code does not work, because changing to EntityState.Deleted removes the object from collection, and for each loop breaks, since the collection is modified...I know that I can overcome this problem by using a for loop or adding objects to delete to some other list first, but I hope maybe there is a pattern that would make my code nicer.

Get SQL Commands (adding, Updating, Deleting) To Work With A VB 2010 Database?

Feb 12, 2012

My project involves making a table database that displays student number, surname, first name, homeroom, and grade avg. Through SQL commands, there must be functions to add, update, delete, search by field, and save records to the database.I have already set the database up just fine and displayed it in a DataGridView. Through the DataGridView, I was able to go to the "Add Query" area, and I successfully made the queries necessary for searching by field. However, when I try to do anything other than a search using the query builder (ie start my SQL command with INSERT INTO or DELETE FROM), I ultimately get the message "Failed to get schema for this query"For example, this SQL code (to add an entry to the database) worked when I was in the Query Builder (and the entry that it made is still in the database), but when I finally tried to confirm it, I got the "Failed to get schema for this query" message.Being unable to add entries to the database this way, I tried to do it with textboxes on a form. Each textbox will have one of the fields, and at the click of a button, they would be put into the table. My code is below. I do not know what is wrong withit. When I run it, my fields do not appear on the DataGridView immediately, but I must run the program again to see it. The time after, the entry is gone. So I am not sure how exactly such entries are to be saved.

Does Outlook 2003 Support ICal 2.0 Spec For Updating And Deleting A Calendar Item

Jul 8, 2009

We are working on an asp.net 2.0 web app that emails users an ical to save to their outlook 2003 calendar. We noticed none of the code to update or delete an item seem to work even though the ical 2.0 spec supports it. We are curious if Outlook 2003 just ignores this?Does Outlook 2007 act differently?We have situations where an event may change or be cancelled which fires off an email notification but the updated ical just adds a new event, it nevers deletes and or moves the original.

Deleting A Registry Value?

Apr 20, 2011

I have this code which should make my application start on startup or stop it from starting on startup depending on whether a checkbox is checked or not:

If MnuItemAutoStart.Checked = True Then
My.Settings.Startup = True
'This code all works fine, it creates the registry key like clockwork
Dim oReg As RegistryKey = Registry.LocalMachine

[code]....

I have tried running the program as administrator, using a different registry value, turning off all of my antivirus & firewalls and loads of other stuff. The strange thing is that I can delete the registry key in regedit, or any other program, it's just my program won't do it. It works on another program with exactly the same code (same startup code, different program).

Deleting Picture That Is In Use?

Jan 30, 2011

I created a time clock program for a friends business and I added a place for them to use pictures for the employee. It uses the employee number to grab the photos from a folder and displays it (ex. employee #1 would like for 1.jpg). I want to let them change the picture without going to that folder, delete the old one, copy the new one and then rename it. I also let it have a default photo (theres 2, one for females and one for males, which are matched by there gender) just in case they haven't had a photo added yet. My trouble is, if I try to update the photo and delete the old photo, I get an error saying its in use by another process. My code goes like this, check to see if the employee has a photo, if it does, it will delete that photo (this is where I get the error), copy the new photo (already selected in previous code) and then sets the photo. how to release the photo from the project before I delete?

ASP.NET - Deleting Computer Accounts Within AD?

Apr 27, 2012

I'm building out a decommissioning application that will allow an individual to provide an computer name and the utility will go out and purge the computer record from various locations. I'm running into a problem when attempting to delete a computer account from Active Directory. I'm impersonating a service account that only has rights to "Delete All Child Objects" within a particular OU structure. The code below works if I run it with my domain admin account; however fails with an "Access Denied" when I run it with the impersonated service account. I have verified that the permissions are correct within AD as I can launch Active Directory Users and Computers using a "runas" and providing the service account credentials and I can delete computer objects perfectly fine.

Wondering if anyone has run into this before or has a different way to code this while still utilizing my current OU permissions. My gut tells me the "DeleteTree" method is doing more then just deleting the object.

Sub Main()
Dim strAsset As String = "computer9002"
Dim strADUsername As String = "serviceaccount@domain.com"
