Hi All, I am developing a library component which requires some global settings. Personally I don’t like to maintain an xml configuration file for this. An idea strikes for me that to write an abstract class with an abstract method which can override and set global setting by the implementers of this library. The abstract class will look like something like this.

public abstract class LibSetting
{
public int MaxCount { get; set; }

 public abstract void SetCount();

}

The end users will implement this abstract class in their application is as follows.

public class MySetting : LibSetting
{
public override void SetCount()
{
MaxCount = 100;
}
}

To get the end user setting from my library, I am using following code.

public int ShowCount()
{
Assembly asm = Assembly.GetCallingAssembly();

   IEnumerable types = asm.GetTypes().Where(t => t.IsClass && t.BaseType == typeof(LibSetting));

   LibSetting setting =(LibSetting) asm.CreateInstance(types.First().FullName);

   setting.SetCount();

   return setting.MaxCount;

}

This will work perfectly. My doubt is that, is it feasible in architecture level of view? I think the performance of read an xml file and loading a class using reflection would be same ( I didn’t test it). So is this a good practice? Kindly advice me on this. Thanks and Regards, Kannan

Then you have to call Server.ClearError to prevent further error processing.

There are several methods to do this. One option is to use forms authentication and set authorization to the folders you want. A quick search on google gives me this link. http://msdn.microsoft.com/en-us/library/ff648341.aspx[^]

Ok you implemented the page error event to write a string to output stream. It will fire whenever the page encounter an error. So what is your problem? What you want to attain?

It is not the problem of DataReader. When the DataReader is opened, it will hold the connection exclusively. So you can't execute any sql commands when it opened. The solution is to use a separate connection or use a DataSet. P.S : You need to improve your coding standards.

You can track the issue with performance counters.

It depends on your preference. Whatever you do, the resultant html should be neat, simple and follows all necessary standards.

One option is to write a windows service which invokes a send mail function periodically. Another option is to create an MSSQL job. If you are using MSSQL 2005 or higher version, you can schedule a job to execute .NET function via CLR stored procedure.

That number probably an id of the thread in the database. You can create such links using url rewriting. There are many articles in web about url rewriting. MSDN[^]

It is because you converted the selecteditem to an object which doesn't have the num property. What is projectname.int? projectname is a class? Can you please show the code that you use to bind the dropdownlist?

Declare arrValues with a specific size. Like this

Dim arrValues() As Double = New Double(dt.Rows.Count - 1) {}

Controlling browser buttons is an idiotic idea. Actually you cant do it with 100% perfection.

You need to define css styles for printable and non printable data. This can done by css media types. reference[^] To send the page to printer, use window.print() javascript command

It is a broad subject to answer in few sentences. Look at the performance optimization[^] search results. There are number of techniques to develop high performance asp.net applications

Your html seems ok. %20 means url encoded space. Did you check the values in database? Is there any empty space in url?

You can simply do it with javascript. Jquery have some plugins for tool tip help. To use the help text in javascript, you need some server side code to inject help text from config file to page.

Are you looking for Login View[^] control?

You can't

Open the file and read content using the classes in System.IO, then insert it into sql server. What you tried to accomplish this?

This forum is for asp.net related questions. So please bear it in mind next time. I think you can store it as Unicode. In sql server, nchar, nvarchar and ntext are support Unicode.
