Using Crypto Obfuscator would give you good protection - it has various obfuscation and protection techniques like method call hiding, control flow obfuscation besides usual like symbol renaming, string encryptin, etc.

The former allows you to determine, at runtime, the object to be instantiated, while the latter requires that you know that information at design time. ___________________________________________ .\\axxx (That's an 'M')

Static : - Which shared the value with multiple instance Readonly :- once define.. you can change the value through constructor only at the time of creating instance.. Constant :- once define; you can't change it,,

You never have to use either. When defining a group of similar classes you may find it beneficial to define an interface (or more than one) that specifies what things the classes have in common. If there is some common code that the classes should share, you may want to put that code in a base class. If that base class itself should not be instantiated, then you may want to mark it as abstract. In the long run, you probably should always define an interface whenever you define a base class.

Wherever you can - Generics is a very broad subject and it has many applications. It allows your code to work with more than one type at runtime with type safety. If you use a generic List instead of an object array, there's no boxing/unboxing happening at runtime which actually improves performance by orders of magnitude. And there are millions of advantages. I would suggest that you go over the articles on the Internet to learn generics. Initially it may seems to be a complicated technology, but once you start appreciating its purpose, thing will be easy for you. Essential C# 2.0: Chapter 11: Generics[^]

There are more differences. In one case, a friend of many was working with MasterPages and Master-MasterPages. In Web Application, FormC can access FormB, FormA and so on easily. You can't do the same in Web Sites. Web Sites have the advantage only of being able to be loaded "partially" (as each form can be loaded independently).

Flexibility. A method that accepts a List can only accept a List (or something derived from List), whereas a method that accepts an IList can accept anything that implements IList, not just List.

hi i have same problem the below link helped you: http://stackoverflow.com/questions/290121/asp-net-ajax-error-sys-webforms-pagerequestmanagerparsererrorexception[^] in this post describe about reason of this problem and solutions in brief, if you have update panel tag modify your tag like this: instead of button1 write your object name

1st Approach <script type="text/javascript"> function ShowImage() { document.getElementById('txtAutoComplete') .style.backgroundImage = 'url(images/loader.gif)'; document.getElementById('txtAutoComplete') .style.backgroundRepeat= 'no-repeat'; document.getElementById('txtAutoComplete') .style.backgroundPosition = 'right'; } function HideImage() { document.getElementById('txtAutoComplete') .style.backgroundImage = 'none'; } </script> Now write this code in Page_Load event of aspx page protected void Page_Load(object sender, EventArgs e) { this.txtAutoComplete.Attributes.Add ("onkeypress", "ShowImage()"); this.txtAutoComplete.Attributes.Add ("onblur", "HideImage()"); } +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 2nd approach This approach works if you are using newer versions of AjaxControlToolkit.dll (Version 1.0.20229.20821 or later) For this write the above mentioned javascript in head section of html markup of page. Now in source of autocomplete extender add OnClientPopulating="ShowImage" and OnClientPopulated="HideImage" <ajaxToolkit:AutoCompleteExtender runat="server" ID="AutoComplete1" BehaviorID="autoComplete" TargetControlID="txtAutoComplete" ServicePath="AutoComplete.asmx" ServiceMethod="GetCompletionList" MinimumPrefixLength="1" CompletionInterval="10" EnableCaching="true" CompletionSetCount="12" CompletionListCssClass= "autocomplete_completionListElement" CompletionListItemCssClass= "autocomplete_listItem" CompletionListHighlightedItemCssClass= "autocomplete_highlightedListItem" onclientpopulating="ShowImage" onclientpopulated="HideImage"> </ajaxToolkit:AutoCompleteExtender> <script type="text/javascript"> function ShowImage() { document.getElementById('txtAutoComplete') .style.backgroundImage = 'url(images/loader.gif)'; document.getElementById('txtAutoComplete') .style.backgroundRepeat= 'no-repeat'; document.getElementById('txtAutoComplete') .style.backgroun

The SQLDataSource classes are not suitable for real world programming. If you're doing a professional project, you should not use them. What you're describing seems to me to be a bug in the classes tho, what have you turned up on google, I'd expect other people would have asked the same question.

May be the problem is master page path. I don’t think ‘~CommonMaster.master’ is valid.

md_azy wrote: Why we are using ClientID while using master page ? Whenever a server control is inside a container control (like the Content control used by content pages), the id of the container is prepended to the id of the control to ensure that every id in the page is unique. So, it's not only when you have a master page. Despite everything, the person most likely to be fooling you next is yourself.

Ok, I can put it another way: That's not possible. Despite everything, the person most likely to be fooling you next is yourself.

If using a .NET language, set the parameter object's Direction property to ParameterDirection.Output (or, if you're passing values in through this parameter as well, ParameterDirection.InputOutput). The parameter will then be set to this value once all resultsets have been read to the end. DoEvents: Generating unexpected recursion since 1991
