  • T-SQL Script to Delete All The Relationships Between A Bunch Of Tables in a Schema and Other Bunch i

    - by Galilyou
    Guys, I have a set of tables (say Account, Customer) in a schema (say dbo) and I have some other tables (say Order, OrderItem) in another schema (say inventory). There's a relationship between the Order table and the Customer table. I want to delete all the relationships between the tables in the first schema (dbo) and the tables in the second schema (inventory), without deleting the relationships between tables inside the same schema. Is that possible? Any help appreciated.

  • ASP.NET Session expires in no time?

    - by Galilyou
    Weired problem! ASP.NET Session expires instantly. In my web.config I have this session settings: <sessionState mode="InProc" timeout="10000" /> AFAIK the timeout attribute's value is in minutes and can't be greater than 525,600 minutes (1 year). I don't understand what I am doing wrong here. Why is the session expiring. Is it a server memory issue? I don't think so, the server is pretty descent and it has only one site which isn't doing much after all. Ideas? EDIT: After setting the cookiless attribute to true, and while noticing the session id on the url, I can see that the session id CHANGING. I assume that this means the session is expiring. The IIS Settings are correct AFAIK (the enable session state checkbox is checked, and the value of the time is 20). A Picture is worth 100 words:

  • WCSF vs MEF, What's Best For Me?

    - by Galilyou
    Hey fellows, I'm working on a large web application that includes many modules (CRM, Inventory, Administration, etc.) What I want to accomplish is to be able develop each of these modules independently (the UI, Core Logic, DataAccess Logic, and all) and then integrate them all together into a core module (this integration should only be a change in the configuration file). For example, if I have a core module named Host, I should be able to add the CRM module to the host module by simply adding this line to the host's configuration file: <module name="CRM" /> I did some reading on the WCSF, and found that it can help integrate some modules together, but it really doesn't offer so much help in terms of integrating those UI elements. Some friends suggested MEF for the job, but I haven't looked at that yet. What do you guys think? Is it possible to achieve this level of modularity, and how much work do I have to put into it to get it working?

  • Why doesn't is operator take in consideration if the explicit operator is overriden when checking ty

    - by Galilyou
    Hey Guys, Consider this code sample: public class Human { public string Value { get; set;} } public class Car { public static explicit operator Human (Car c) { Human h = new Human(); h.Value = "Value from Car"; return h; } } public class Program { public static void Mani() { Car c = new Car(); Human h = (Human)c; Console.WriteLine("h.Value = {0}", h.Value); Console.WriteLine(c is Human); } } Up I provide a possibility of an explicit cast from Car to Human, though Car and Human hierarchically are not related! The above code simply means that "Car is convertible to human" However, if you run the snippet you will find the expression c is Human evaluates to false! I used to believe that the is operator is kinda expensive cause it attempts to do an actual cast that might result in an InvalidCastException. If the operator is trying to cast, then the cast should succeed as there's an operator logic that should perform the cast! What does "is" test? Does test a hierarchical "is-a" relationship? Does test whether a variable type is convertible to a type?

  • Is it possible that __doPostBack() would ever send a GET request?

    - by Galilyou
    I'm having a problem with telerik RadGrid, I want to enable multiple row selection. I also want to go to the server whenever a row is selected or deselected. I created a javascript function to handle the Grid's client side events (OnRowSelected, and OnRowDeSelected). The functions look like this: function onOperationRowSelected(sender, eventArgs) { __doPostBack("<%=myControl.ClientID %>", "rowSelected:" + eventArgs.get_itemIndexHierarchical()); } The other function is very similar, the only difference is that it sends the string "rowDeselcted" instead of "rowSelected". On Page_Load I check to see if the request is a Post request using "IsPostBack" and if so, I check to see if it's a rowSelected or rowdeselected. My problem is when I select a first raw on my grid, a Post request happens (which is expected), however, when I select the second row, a GET request is issued, which (obviously) will result in IsPostBack returning false. What am I missing here?

  • Is this a hole in dynamic binding in C# 4?

    - by Galilyou
    I've seen a very interesting post on Fabio Maulo's blog. Here's the code and the bug if you don't want to jump to the url. I defined a new generic class like so: public class TableStorageInitializer<TTableEntity> where TTableEntity : class, new() { public void Initialize() { InitializeInstance(new TTableEntity()); } public void InitializeInstance(dynamic entity) { entity.PartitionKey = Guid.NewGuid().ToString(); entity.RowKey = Guid.NewGuid().ToString(); } } Note that InitializeInstance accepts one parameter, which is of type dynamic. Now to test this class, I defined another class that is nested inside my main Program class like so: class Program { static void Main(string[] args) { TableStorageInitializer<MyClass> x = new TableStorageInitializer<MyClass>(); x.Initialize(); } private class MyClass { public string PartitionKey { get; set; } public string RowKey { get; set; } public DateTime Timestamp { get; set; } } } Note: the inner class "MyClass" is declared private. Now if i run this code I get a "Microsoft.CSharp.RuntimeBinder.RuntimeBinderException" on the line "entity.PartitionKey = Guide.NewGuid().ToString()". The interesting part, though is that the message of the exception says "Object doesn't contain a definition for PartitionKey". Also note that if you changed the modifier of the nested class to public, the code will execute with no problems. So what do you guys think is really happening under the hood? Please refer to any documentation -of course if this is documented anywhere- that you may find?

  • Do I have to remove VS 2010 beta1 in order to get a web app to work on asp.net 2.0?

    - by Galilyou
    I think the title is enough :). I have VS 2010 beta1 installed, and I wish to run an asp.net mvc application on my local IIS. The problem is, the asp.net 4.0 runtime is selected by default for all the web sites, when I try to change it to asp.net 2.0, I get the following error message: I click yes, then ok, and when I get back to the ASP.NET tab of my site's properties, I see the 4.0 version is selected back again! Do I have to remove VS 2010 in order to get this to work? (hopefully not) Ps: I'm using windows XP and IIS 5.1

  • Help improve this Javascript code?

    - by Galilyou
    Hello SO, In short, I'm dealing with Telerik's RadTreeView, and I want enable checking all the child nodes if the user checked the parent node. Simple enough! OK here's my code that handles OnClientNodeChecked event of the TreeView: function UpdateAllChildren(nodes, checked) { var i; for (i = 0; i < nodes.get_count(); i++) { var currentNode = nodes.getNode(i); currentNode.set_checked(checked); alert("now processing: " + currentNode.get_text()); if (currentNode.get_nodes().get_count() > 0) { UpdateAllChildren(currentNode.get_nodes(), checked); } } } function ClientNodeChecked(sender, eventArgs) { var node = eventArgs.get_node(); UpdateAllChildren(node.get_nodes(), node.get_checked()); } And here's the TreeView's markup: <telerik:RadTreeView ID="RadTreeView1" runat="server" CheckBoxes="True" OnClientNodeChecked="ClientNodeChecked"></telerik:RadTreeView> The tree contains quite a lot of nodes, and this is causing my targeted browser (ehm, that's IE7) to really slow down while running it. Furthermore IE7 displays an error message asking me to stop the page from running scripts as it's might make my computer not responsive (yeah, scary enough). So what do you guys propose to optimize this code? Thanks in advance
