.NET GENES

Hello! The previous version of ExtenderControlBaseDesigner does not require T as parameter. However, in recent versions you might notice that the class is declared with T. Here's a sample declaration: AjaxControlToolkit.Design.ExtenderControlBaseDesigner<T> T means AjaxControlToolkit.ExtenderControlBase. In order for the Custom Extender Designer to work, supply the T with class that inherits the ExtenderControlBase. This sample class inherits the ExtenderControlBase: public class CustomPanelExtender : ExtenderControlBase { //your code goes here.... }

When adding ajax extenders to asp.net server controls using Smart Tag, you often encounter an issue such as Show Smart Tag is greyed out/disabled. The best thing to do is to use the latest stable version of AjaxToolkit. And then, reset the toolbox. Sometimes, you have to close the Visual Studio IDE just to make sure. IDE Version: Visual Studio 2010 Professional Ajax Toolkit Binary: AjaxControlToolkit.Binary.NET4 (Stable Version) Cheers!

The function below retrieves the top Freight amount specified by date range values use CompanySales IF object_id (N 'dbo.GetTopFreightValueRange' , N 'FN' ) IS NOT NULL drop function GetTopFreightValueRange go create function GetTopFreightValueRange ( @startDate nvarchar(50), @endDate nvarchar(50) ) returns decimal(10,2) as begin declare @ result varchar(50) set @ result = ( select FreightAmount from dbo.Orders where CONVERT (VARCHAR(10), ShippedDate, 120) >= @startDate and CONVERT (VARCHAR(10), ShippedDate, 120) <= @endDate ) return @ result end go -- select dbo.GetTopFreightValueRange('1996-11-01','1996-11-30') as freight_value;

Here's a simple function that will return the freight amount in decimal format. use Your_Database_Name if object_id (N 'dbo.getFreightValue' , N 'FN' ) is not null drop function getFreightValue go create function getFreightValue ( @salesID nvarchar(50) ) returns decimal(10,2) as begin declare @ result varchar(50) set @ result = ( select Freight from dbo.Orders where OrderID = @salesID ) return @ result end go -- run function -- select dbo.getSomeValue(10248) as freight_value; Cheers!

When running a simple asp.net mvc project, I encountered an error which states the Model.FindAll() could not be performed. Model is a class that maps to a database table. After tracing my codes, I found out that I have mispelled the database name in my web.config as specified below: <add key= "connection.connection_string" value= "Data Source=MyComputerStation\SQLEXPRESS;AttachDbFilename=|DataDirectory|\Blogs.mdf;Integrated Security=True;User Instance=True" /> What I did was change the database name from Blogs to Blog . That's it! :) Greg

Usually, we set an asp.net connection string directly in the app.config. However, we can also do it Properties.Settings. As soon as we saved the name and value, it will reflect in the app.config. Here's a sample image as reference: Cheers!

The code below does not allow pass by reference to be used in UI threading particularly method Invoker. private void ShowPassMeta( ref int passedSound) { if (lblPassSoundex.InvokeRequired) { lblPassSoundex.Invoke((MethodInvoker) delegate { ShowPass( ref passedSound); }); } else { lblPassSoundex.Text = (++passedSound).ToString(); } } The solution is to store the method parameter in another variable as shown below: private void ShowPassMeta( ref int passedSound) { var passedSound1 = passedSound; if (lblPassSoundex.InvokeRequired) { lblPassSoundex.Invoke((MethodInvoker) delegate { ShowPassMeta( ref passedSound1); }); } else { lblPassSoundex.Text = (++passedSound1).ToString(); } } Cheers!
