c# - When TextBox TextChanged event is fired? -

-

My question is:

As we know that for the VestStart textbox, storage and reinstallation The checkbox and such control values ​​are not done by the LoadPostData () method that implements the iPostBackDataHandel interface.

And even after the load level, we know that RaisePostBackEvent is in phase and clicking or pushing related events such buttons, if the text is turned into a text box, its TextChanged event will be removed .

So, if the system changes the text, then if the viewstation is not responsible for that, and which mechanism actually removes the text box text changage event?

I'm really confused at this point.

Thanks in advance

I think this is working like this :

Textbox Control IPostBackDataHandler implies instead of IPostBackEventHandler because it has been removed by its text state. So if there has been a change in postwall which 

  if (present value == tap ||! Present value, eclus (post value)) {text = post value; Return true; }

Keep the part so it returns true and executes the TextChanged at the end. Pff is confusing but it sounds easy. 

  using the system; Using System.Web; Using System.Web.UI; Using System.Collections; Using System.Collections.Specialized; Public Location MyTextBox: Control, IPostBackDataHandler {Public String Text {Received {Return (String) ViewState ["Text"]; } Set {ViewState ["text"] = Value; }} Public events event handler text change; Public Virtual Bull Load Post Datas (String PostData, Nomewoles Collection Postcolling) {String Attribute Value = Text; String Post Values ​​= Selection of Post [postDataKey]; If (present value == tap ||! Current value.Equals (post value)) {text = post value; Return true; }       return false; } Public Virtual Zero RaisePostDataChangedEvent () {OnTextChanged (EventArgs.Empty); } Protected Virtual Zero Onnetxt Change (EventArgs E) {If Text Changed! = Null) Text changed (this, E); } Safe Override Zero Submission (HtmlTextWriter Output) {output.Write ("& lt; INPUT Type = text name =" + this.UniqueID + "value =" + this.Text + "& gt;"); }}}

I am getting an error with php in order to format mysql_query () in php to format this string What is the right way? SELECT SELECT SELECT (*) Agents @AgentCount; User_Agent_English, User_Angent_Oursal, US.___Gent_Aginal, COUNT (User_Agent_Percade) ACC, COUNT (*) / (AgentCount) Percentage by agents user_agent_preser order DEC limit limit 50; In PHP, how am i setting $ query $ query = "SELECT count (*) agents @ agentcount; SELECT user_agent_parsed, User_agent_original , COUNT (user_agent_parsed) ascount, COUNT (*) / (@AgentCount) as a percentage by user_agent_parced by URI date DESC limit 50 "; This exact query will work properly if I put it in MySQL directly through a command line session. Do I need to release two separate php calls from mysql_query () and store the results first? I get the following error: There is an error in your SQL syntax; Instead of using a sub-selection and instead of using the 'SELECT user_agent_parsed, user_agent_original, ne...

url rewriting - How to implement the returnurl like SO in PHP? -

-
This URL should work even after the rewrite. Is this possible? Otherwise, I can only hardcoded everything If you are trying to create a login system with redirection You need to use the HTTP_REFERER header to find out where the user came from so that you can send it back there. The best way to do this is to use something like this in your login form: // - Login php & Lt; Input type = "password" name = "password" /> & Lt; Input type = "hidden" name = "returnrelale" value = "& lt ;? php echo $ redirectURL ;? & gt;" / & Gt; & Lt; / Form & gt; Please note that some ISP, browser or proxy will delete the referrer header, so you can not rely on each user to work fully. If you use a statement, to check whether the header exists or not, you can send those users back to the homepage or whatever. Edit If you are looking to use $ _SERVER ['REQUEST_URI'], if you are running Apache It sho...

Which Python client library should I use for CouchdB? -

-
I am starting to experiment with CouchDB because it looks like we have the right solution to certain problems That all the work will be on a new project, which does not have any legacy dependency, which the client library will suggest you use, and why? If we overlap any of the OS. Freeband is available only in the collection of its ports, but asks to use the library's project website. None of those people are Ubuntu, which is only with ships, since those two OSAs are not common in libraries, I am probably installing something from source (and hopefully if I have time, then Ubuntu and FreeBSD People pack the package). For those interests, I want to use CouchDB as a convenient intermediate storage space for data passed between different services - think of a message bus system, but less formalities with. For example, we have daemons that download and pars the web page, then send an interesting bit to other daemons for further processing. Many of them are ill-defined until the...
