How To Use SqlDependency In A Class

Mar 15, 2011

When I implement a SqlDependency watcher in a windows form, everything works fine as long as I invoke my "OnChance" event to the ui thread.

private void dependency_OnChange(object sender, SqlNotificationEventArgs e)
{
if (this.InvokeRequired)[code]....

The same happens when I comment these lines in the windowsform, so I think that the _OnChance Event is on a different thread than the "thread" I'm using when I call SetSqlWatcher the first time.

I also tried to implement ISynchronizeInvoke (with the help of GenericSynchronizingObject in libary http://nitoasync.codeplex.com). I debugged, saw, that the code has to invoke it the first time, but it also hangs in "SqlDependency.Stop"...

SqlDependency Vs SqlCacheDependency

Oct 11, 2010

What are the key differences between these and when should they be used? My initial understanding was that SqlCacheDependency used polling but I've read it doesn't have too for ASP.NET 2.0. I want to know which is most appropriate for caching of linq queries under ASP.NET web server. This will be ASP.NET 3.5.

SqlDependency / Want To Use It To Monitor Several Tables (around 10)

Aug 6, 2010

I'm using SqlDependency to control my cache. I want to use it to monitor several tables (around 10). There should be one SqlDependency per watched table.

Should I create for each of them code like that:

public void CreateDependency_Table()
{
if (connectionStringSettings != null) [code]....

or can I reuse something between them? Like connection?Is this the preferred way of setting multiple notifications?

C# - Webservice Complex Types And Class Inheritance - Use The Properties Of The Base Class?

Mar 13, 2010

Using the following Webservice definition using aClientArgs as a complex type:

[System.Web.Script.Services.ScriptService]
public class Controller : System.Web.Services.WebService {
[WebMethod]
public void save_client(aClientArgs client)
{
// Save client data
}
}
Then defining aClientArgs as a sub-class:
public class aArgs
{
public string id = null;
public string name = null;
}
public class aClientArgs : aArgs
{
public string address = null;
public string website = null;
}
Returns the following WSDL fragment for the save_client args:
<save_client xmlns="http://tempuri.org/">
<client>
<address>string</address>
<website>string</website>
</client>
</save_client>
When I'm expecting the following:
<save_client xmlns="http://tempuri.org/">
<client>
<id>string</id>
<name>string</name>
<address>string</address>
<website>string</website>
</client>
</save_client>

So it appears that the .NET WebService is not treating inherited properties as arguments/variables for purposes of a web service. How do I get .NET to also use the properties of the base class?

Mvc - Can Set A Custom Class As The Default Base Class For Controllers In MVC3

Feb 15, 2011

I'd like to inherit all my controllers from a custom base class that I write myself. I can change the line every time I add a new controller, but it would be nicer if I could somewhere specify the default value that gets set there. That way I wouldn't need to worry about forgetting this, and other people who get added to the project later on would have an easier time.

MVC :: Trying To Setup A Base Product Class That Will Be Inherited By A More Specific Class Later?

Dec 16, 2010

In my MVC project, I am trying to setup a base product class that will be inherited by a more specific class later. Here is my scenario. I have a table called ProductBase, it contains three fields, BaseProductId(PK), CatalogNum, and ListPrice. Every product in the system will share these attributes. Next, I have a table called Shirt, with three fields BaseProductId(PK, FK), Color, and Size.

I then setup an Entity Data Model that pulled in both of these tables and created classes BaseProduct and Shirt. So, in my model, I want to do something like this:

[Code]....

The main problem I have with this, is that if I do any kind of condition on CatalogNum or ListPrice, then my performance goes to crap. One of the main things we will want to do is something like this:

[Code]....

This takes an enormous performance hit, and I suspect it is because the partial class above returns to the database for each shirt.

The other problem I have with this approach, is that I cannot force the properties for the Shirt. What if I make a change to the BaseProduct? What happens when I have multiple product types, will I have to repeat this code? I assume I will need to make a change with the entity data model, but I am unsure where to begin.

For showing errors I want to put showMessage funtion in PageBase as well so that I may have not put it in every page and it will easy to manage this way.

Probem is that how PageBase class will access a control which is in aspx page in its child class (child class of PageBase) .

Getting Child Class Type From Parent Class Parameter In C#

Jul 6, 2010

I am going to have multiple "types" of an object and I am really not sure how best to retrieve/save those multiple types without having a separate save/retrieve for each type.

My classes:

[Code]....

I hope this makes sense. I'd rather not add a "type" column as I have this in another part of my database and I am not really liking it too much

UPDATE

Here's more info/questions for clarification, if necessary.

I'm really at a loss for how to incorporate them into my repository pattern.

When I call getEvaluation, I want it to return an abstract Evaluation, but I'm struggling with this code. Same with Saving - any insight on this would be excellent

UPDATE 2

Database:
Evaluations
Id (PK)
Comment
EvaluationType1
Id (FK to Evaluations.Id)
Field
EvaluationType1
Id (FK to Evaluations.Id)
Field

So, in getEvaluation(int id), I need to figure out what type of Evaluation they want. Does this mean I should pass in a type? Same is true in saveEvaluation, But I can do a switch/function map to see what Type it is.

C# - Store Class Instance (helper Class) In Cache?

Jun 30, 2010

I have a class instance which is created by using Activator.CreateInstance() method. That class instance contains helper methods which are frequently used throughout the application. In order to avoid creating the instance multiple times, I'm just thinking about implementing an appropriate caching mechanism. The following consideration should be taken into account:

1) I can't use static class and methods.
2) There are around 6 instances (1 instance per class) per App Domain.

Here When i create object of Class InheritingOneConstruntor value of public field var1 is zero at last.

All var1 means at all locations where var1 is used i.e., in base class and in child class.But the moment control exits New() constructor of base class, var1's value again becomes zero.
