• Re: html server controls Vs ASP.Net Web Controls

  1.One html control corresponds to exactly one HTML element, but web controls can render to any html element, single or compositional. So there are TextBox html controls and web control, Table html control and web control, but there is only GridView web control, there is no GridView html control. 2.web control provides more features than html controls. For example, only web control TextBox has AutoPostback.

• Re: The same code can open oracle connection in WinForm and Console App, but not in asp.net

  I think the exception results from the incompatibility of the x86 version of Oracle client and the x64 version of the Win 2003 and ASP.NET. But i am not 100% sure. I reconstruct the software environment as follow and everything is ok, without any exception. # the client machine: WINDOW XP x86 running IIS 6.0, ORACLE clint x86 10G,.NET Framework 3.5 x86(without sp1) # the server machine: windows 2003 server X86 running ORACLE 10G

• IE gets less and less responsive in AJAX

  I have a ajax program that needs to do persistent ajax broswer-IIS communications,just as a real time stock price showing program. There are 14 numbers to be updated every 5 seconds on the web page. All functions are ok. The problem is that after the IE window has been runing for more than several hours,the IE window is not responding. In the Windows' Task Manager, the iexplorer.exe process is consuming 30% of the CPU time. If TCPTrace is used to track the HTTP communication between IE and IIS

• Re: IE gets less and less responsive in AJAX

  thank you for your reply. I am using IE 6 [quote user="XIII"] Make sure that when you define eventhandlers that you also unwire them when needed. Alwasy clean up the things you created before you get leaks. [/quote] Do you mean the server-side ASP.NET code? There are Timer's Tick event handler, but it uses no unmanaged resource. And the managed resource will be cleaned up by GC. Why do I have to unwire eventhandlers?

• Re: IE gets less and less responsive in AJAX

  IE6 is known to be leaky when it concerns javascript (ajax)? But there are other similar ajax web page on the Internet, when browsering them in IE 6, it seems(NOT 100% sure, just no similar experience) there is no such problem.

• Re: IE gets less and less responsive in AJAX

  hi, Kris. Do you think that there may be somthing wrong in server-side and this causes client-side to become less and less responsive? I use UpdatePannels, so there is no self-developed javascript.

• Re: IE gets less and less responsive in AJAX

  Following your advice, I have search several articles about ie6's GC. Now I know that I can solve the problem in two ways: 1. throw away update pannels and use ajax webservice. But if way 2 can solve the problem, i don't want to rewrite the code. 2. Fix the IE 6 GC problem. There are two sub-ways: 2.1. install Microsoft Windows Script 5.7 for IE 6. 2.2 Use IE7, IE8, FireFox. In http://blogs.msdn.com/ericlippert/archive/2003/09/17/53038.aspx , I found the following: "However, there are

• Re: The same code can open oracle connection in WinForm and Console App, but not in asp.net

  hi, thank you for replay. But it seems it is wrong to use "provider", since i am using OracleConnection rather than OldDbConnection. I am using OracleConnection, so it is right to use the ".NET Framework Data Provider for Oracle" in http://www.connectionstrings.com/oracle#p19 . There is no need to use "provider" key word.

• Re: btn click event not always fired

  because the line "btn.Click += new EventHandler(btn_Click);" is within the GetMenu method, so this line is not executed in every http request. Can you give some details on where/when the GetMenu method is called?
