Deleting Old Applications
Feb 2, 2010After some trial and error I'm stuck with some applications in my database. I tried to delete them, but wound up with error about referential integrity. Is there any way to delete all of this?

C# - Deleting From Repeater Item - Erroneous Deleting?
Sep 27, 2010I have a repeater which binds a set of data. Within this repeater is a column with various controls for updating, deleting, etc. These are image buttons which fire an onclick event such as "DeleteRecord". All this does is fire a stored procedure, passing in the ID of the record to delete from the CommandArgument of the object.
This works wonderfully... except for one rather huge problem. Once you delete a record, if you refresh the page, the record where the first deleted record used to be gets deleted. For instance... if I have 4 records
1 Record1
2 Record2
3 Record3
4 Record4
and I delete record 2... The page reloads with (which is fine):
1 Record1
3 Record3
4 Record4
...if I then hit refresh...
1 Record1
4 Record4
I assume this is because the erroneously deleted object (record3) is now in the same hierarchical place as the old object used to be and .net therefore doesn't know the difference, the page refreshes and fires the onlick event, grabbing out the command argument of the new object and deletes based on the ID as obtained from the commandargument of the new object. This is obviously a huge problem, if a client did this it would destroy data erroneously and I'm at a loss here. Is there any way to stop this from happening? I'm not sure if there is a better way to go about doing things or not. If there isn't, I need some sort of way to tell the page not to execute the event or to cross reference the ID of the object that is intended for deletion against the object itself...
Code below for convenience...
EDIT Wrapped a LinkButton around it because I have some jquery code in here as well which stops the page execution to wait for user confirmation. Pressing "ok" continues page execution.
<asp:LinkButton ID="oDeleteLink" CssClass="oDeleteIcon" CommandName="Delete" CommandArgument='<%# Eval("iAccountID") %>' runat="server">
<asp:ImageButton ImageUrl="/files/system/icons/trash-steel-16.png" ToolTip="Delete This Account" AlternateText="Delete" ID="oDeleteIcon" runat="server" />
</asp:LinkButton>
protected void oAccounts_ItemCommand(Object Sender, RepeaterCommandEventArgs e) {
if (e.CommandName == "Delete") {
int ID = e.CommandArgument.ToString().Numeric();
db.SPs.SpDeleteAccount(ID).Execute();
UI.Confirm(uiBroadcast, "Account has been deleted", "300px");
BindAccounts();
}

WCF / ASMX :: Building Services To Work With Web Applications And Console Applications?
Jun 7, 2010I've been worked with web services so far, and I'm interested in expanding my services to console applications as well so I started digging up with WCF but I'm conserned that I won't be able to use the HttpContext collection that I've been used to do with web services one important thing which is to generate a random value from HttpContext.Current.Request.ServerVariables["ALL_HTTP"] that I need to reckon if it's the same or at least near what machine that is calling my service. How can I overcome this problem?
I need to know what machine is calling to count the number of attempts to login into my system for example. So must do it inside of the svc code otherwise if I let the client inform what ip address or what computer he is using, anyone could forge this argument and surpass by another machine. May be I'm approaching this matter wrongly. And I should count the number of attempts per state session, but how is it done?
Configuration :: Deploying Web Applications With Sub Web Applications?
Apr 22, 2010Our corporate intranet is designed so that each web application is a child application in the primary application.. Everything has worked fine with Visual Studio 2008 and even in 2010 running the website locally works great, the output directory for the child apps is ..in and the ProjectName.dll copies to that directory.. When I do a publish however it does not and I have to manually copy the dll from the bin folder in the project folder to the parent bin folder, this isn't hard of course but more of a pain in the butt each time I need to publish something. I made sure the output directory is correct for both debug and release yet on publish is just copies it to the child bin and not the parent bin as needed.

View 2 RepliesSqlCacheDependency Not Deleting What Is In Cache
Feb 2, 2011I am using sqlCacheDependency, and usually upon any changes in the database cache items get deleted automatically. In my case everything works allright, but I had to buy a new laptop and I moved the same exact database and the same exact webapplication to the new laptop. Unfortunately, on my new machine the cache items remain in cache upon data updates on the database.
I have enabled servicebroker on the database, and started it in the application_start event in my webapplication. I also ran the following:
GRANT SUBSCRIBE QUERY NOTIFICATIONS
TO "Naji-pcNaji"
The differance I see on my laptop from my other machine is that the database is named (local). Naji-pc is the name of my machine.

Deleting Entity With Child Relationships
Apr 10, 2010EF is so frustrating. I can't seem to be able to get my head around what I need to do so I can delete an object. I seem to be able to remove the object but not the related child objects. Can anyone tell me what is the rule of thumb when you want to delete all related child objects of a given object? I've tried loading all related objects like this:
Entry entry = ModelContext.GetObjectByKey(new EntityKey("ModelContainer.EntrySet", "Id", id)) as Entry;
entry.ChildEnteries.Load();
if (entry != null)
{
ModelContext.DeleteObject(entry);
ModelContext.SaveChanges();
}
I get errors related to the relationships: A relationship is being added or deleted from an AssociationSet 'EntryEntry'. With cardinality constraints, a corresponding 'Entry1' must also be added or deleted. Why can't I just load the object using modelcontext.GetObjectByKey and remove it along with its child objects? My other question is can I delete an object using Entity command like so? DELETE e from objectset as e where e.id = 1 I've tried few variations and all of them throw exceptions.
