• How to add multiple handlers to an attached event in XAML ?

  - by Gishu

  I want to add 2 handlers to a particular event like shown above. However this won't compile - 'attribute can be set more than once'. I have multiple methods because they do different things (are named appropriately). e.g. the first handler has nothing in common with the second. My other option was to kludge a SetFlagForCursorTrackingAndCheckForViewLink method - which is "Yech!". Any ideas ?

• Email SMTP validator

  - by Hrvoje

  I need to send hundreds of newsletters, but would like to check first if email exists on server. It's called smtp validation, at least i think so, based on my research on net. There's several libraries that can do that, and also a page with open-source code in asp (http://www.coveryourasp.com/ValidateEmail.asp#Result3), but I have hard time reading classic asp, and it seams that it uses some third-party library... Does someone have code for smtp validation in c#, and/or general explanation of how it works?

• Apache using 100% CPU, once again

  - by CBenni

  Recently, apache2 started using 100% of CPU power: top gives me From other, similar threads, I took the tip to use mod_status. Aside from HUGE amounts of NULL requests, it gives: CPU Usage: u2.16 s1.32 cu0 cs0 - .0835% CPU load 1.2 requests/sec - 17.6 kB/second - 14.6 kB/request 8 requests currently being processed, 42 idle workers The access and error logs do not show anything surprising or intriguing at all. Note the .8% CPU usage. Another tip was to use strace: root@server:~# strace -p 1956 Process 1956 attached - interrupt to quit restart_syscall(<... resuming interrupted call ...> And remains like this for at least half an hour, without producing any additional output. Restarting apache fixed the problem for less than a second The server runs a few custom python scripts aswell as a django-powered website on apache2 (up-to-date), but even turning the scripts off (or not having them active in the first place) did not change anything. After I stopped apache and powered my server off, powered it on a few minutes afterwards and restarted all my services, the CPU usage remained low for several hours, just in order to pop up again randomly (?) The DigitalOcean CPU stats on my server are: You can see how the CPU usage was super high for almost half a day until I restarted the bot - just to remain stable for several hours and then pop up again. I am completely at a loss of words and don't know what I could do to find out what piece of my code is giving me these problems or if apache itself is the cause... Therefore I would greatly appreciate any hints to the questions: What else can I try to do? Which things might I not have checked? Is this definitely in my own code? How do you find what part of python code crashes an app via a infinite loop or similar?

• PHP function which does syntax color parsing for multiple languages?

  - by Edward Tanguay

  I'm doing a PHP site which displays code examples in various languages (C#, PHP, Perl, Ruby, etc.). Are there any PHP functions which add syntax coloring for these and other languages? If not, I would at least like to find that one built-in PHP function which does syntax coloring for PHP code, can't find it anymore. Thanks.

• sigsetjmp and siglongjmp inside signal handler

  - by EpsilonVector

  How do I: sigsetjmp inside the handler and then return from the handler such that the signal will be unmasked once I siglongjmp back to this point? In pseudo code this is sort of the function that I have: signal_handler(){ if(sigsetjmp(env[i++])) return; else siglongjmp(env[i]); } It's supposed to be the context switch code for user threads in Linux.

• Using google maps API, how can we set the current location as the default set location using map.set

  - by vs1984

  I am writing Javascript code using Google maps API. map = new google.maps.Map2(document.getElementById("map_canvas")); map.setCenter(new google.maps.LatLng(37.4419, -122.1419), 13); The above code sets the default location of the map canvas to Palo Alto. How can we write the script in such a way that the setCenter function automatically points to the current location of the client?

• Java Socket Connection is flooding network OR resulting in high ping

  - by user1461100

  i have a little problem with my java socket code. I'm writing an android client application which is sending data to a java multithreaded socket server on my pc through direct(!) wireless connection. It works fine but i want to improve it for mobile applications as it is very power consuming by now. When i remove two special lines in my code, the cpu usage of my mobile device (htc one x) is totally okay but then my connection seems to have high ping rates or something like that... Here is a server code snippet where i receive the clients data: while(true) { try { .... Object obj = in.readObject(); if(obj != null) { Class clazz = obj.getClass(); String className = clazz.getName(); if(className.equals("java.lang.String")) { String cmd = (String)obj; if(cmd.equals("dc")) { System.out.println("Client "+id+" disconnected!"); Server.connectedClients[id-1] = false; break; } if(cmd.substring(0,1).equals("!")) { robot.keyRelease(PlayerEnum.getKey(cmd,id)); } else { robot.keyPress(PlayerEnum.getKey(cmd,id)); } } } } catch .... Heres the client part, where i send my data in a while loop: private void networking() { try { if(client != null) { .... out.writeObject(sendQueue.poll()); .... } } catch .... when i write it this why, i send data everytime the while loop gets executed.. when sendQueue is empty, a null "Object" will be send. this results in "high" network traffic and in "high" cpu usage. BUT: all send comments are received nearly immediately. when i change the code to following: while(true) ... if(sendQueue.peek() != null) { out.writeObject(sendQueue.poll()); } ... the cpu usage is totally okay but i'm getting some laggs.. the commands do not arrive fast enough.. as i said, it works fine (besides cpu usage) if i'm sending data(with that null objects) every while execution. but i'm sure that this is very rough coding style because i'm kind of flooding the network. any hints? what am i doing wrong?? Thanks for your Help! Sincerly yours, maaft

• Why didn't C have a boolean data type prior to C99?

  - by frou

  I realise you can just #define some integers, but why didn't C have a dedicated boolean data type before C99? It's such a common occurence in programming and logic, I don't understand the absense of an explicit type and notation.

• Drupal development workflow for teams

  - by Raul Singahn

  In my last Drupal project we were 5 people doing coding and installing new modules, at the same type our client was putting up content. Since we chose to have only one server for simplicity there were times were many people needed to write to the same files like style.css or page.tpl.php or when someones broken code would prevent others from working Are there any best practises for a team that works with Drupal? How can leverage code repositories or sandboxes?

• What is the most efficient procedure for implementing a sortable ajax list on the backend?

  - by HenryL

  The most common method is to assign a sequential order field for each item in the list and do an update that maintains the sequence with every ajax sort operation. Unfortunately, this requires an update to each item of the list every time someone sorts. This is fine for small lists, but what's the best way to implement sorting for larger lists that are constantly updated? I am looking for something that minimizes DB IO.

• Hiding Group Column Names

  - by Robert

  You once replied to a post about hiding list group header names. http://edinkapic.blogspot.com/2008/06/hiding-list-view-group-headers.html I do not write code or jQuery at that. But you mentioned that it would be better to write a solution in jQuery. Would you have code that would hide the group header and colon in a 2003 list (SP v.2)? Do you have any good leads? Thanks.

• Should mutex.WaitOne() inside or before the try/finally block.

  - by chillitom

  Hi Guys, I was wondering which of the following was the suggested pattern when using Mutex (or Semaphores or ReadWriteLockSlims etc.). Should the initial lock happen inside or outside of the try statement? Is it unimportant? _mutex.WaitOne() try { // critical code } finally { _mutex.ReleaseMutex(); } or try { _mutex.WaitOne() // critical code } finally { _mutex.ReleaseMutex(); }
