How to do thread management in C++?

- by Dipan Mehta

We use pthread for thread management in C based systems. pthread is in general compilable by C++ compiler (like g++). However, what are the better ways of abstractions for threads in C++? Also, for making any system to be working in a multi-threaded system, it is also important to make thread safe. What are the standard libraries that requires alternative (installs) to be thread safe or are they unsafe for multi-threaded environments? Is smart pointers, templates require special measures to make it safe? What are the best practices for the thread managements in C++?

Save Zone Implementation in Asteroids

- by Moaz

I would like to implement a safe zone for asteroids so that when the ship gets destroyed, it shouldn't be there unless it is safe from other asteroids. I tried to check the distance between each asteroid and the ship, and if it is above threshold, it sets a flag to the ship that's a safe zone, but sometimes it work and sometimes it doesn't for (list<Asteroid>::iterator itr_astroid = asteroids.begin(); itr_astroid!=asteroids.end(); ) { if(currentShip.m_state == Ship::Ship_Dead) { float distance = itr_astroid->getCenter().distance(Vec2f(getWindowWidth()/2,getWindowHeight()/2)); if( distance>200) { currentShip.m_saveField = true; break; } else { currentShip.m_saveField = false; itr_astroid++; } } else { itr_astroid++; } }

Removing ocurrances of characters in a string

- by DmainEvent

I am reading this book, programming Interviews exposed by John Wiley and sons and in chapter 6 they are discussing removing all instances of characters in a src string using a removal string... so removeChars(string str, string remove) In there writeup they sey the steps to accomplish this are to have a boolean lookup array with all values initially set to false, then loop through each character in remove setting the corresponding value in the lookup array to true (note: this could also be a hash if the possible character set where huge like Unicode-16 or something like that or if str and remove are both relatively small... < 100 characters I suppose). You then iterate through the str with a source and destination index, copying each character only if its corresponding value in the lookup array is false... Which makes sense... I don't understand the code that they use however... They have for(src = 0; src < len; ++src){ flags[r[src]] == true; } which is turning the flag value at the remove string indexed at src to true... so if you start out with PLEASE HELP as your str and LEA as your remove you will be setting in your flag table at 0,1,2... t|t|t but after that you will get an out of bounds exception because r doesn't have have anything greater than 2 in it... even using there example you get an out of bounds exception... Am is there code example unworkable?

jQuery - disable selected options

- by Jeffrey

Need to disable already selected options in select box using jQuery. I'd like it to grey out like asmselect. Test my example here. //JS $("#theSelect").change(function(){ var value = $("#theSelect option:selected").val(); var theDiv = $(".is" + value); theDiv.slideDown().removeClass("hidden"); }); $("div a.remove").click(function () { $(this).parent().slideUp(function() { $(this).addClass("hidden"); }); }); //HTML <body> <div class="selectContainer"> <select id="theSelect"> <option value="">- Select -</option> <option value="Patient">Patient</option> <option value="Physician">Physician</option> <option value="Nurse">Nurse</option> </select> </div> <div class="hidden isPatient">Patient <a href="#" class="remove" rel="Patient">remove</a></div> <div class="hidden isPhysician">Physician <a href="#" class="remove" rel="Patient">remove</a></div> <div class="hidden isNurse">Nurse <a href="#" class="remove" rel="Patient">remove</a></div> </body>

Dynamically writing out li with jquery. Element is not clickable after being written

- by estern

I have have a a function that when a checkbox is checked i dynamically write out an li into a ol that is empty. Code: $(":checkbox").click(function() { var checkedState = $(this).is(':checked'); if (checkedState == true) { var productName = $(this).attr("title"); $("#selectedProductsList").append("<li class=\"productList " + this + "\"><p class=\"removeIcon\"><img src=\"images/remove-icon.png\" alt=\"Remove Product\" /></p><span class=\"productName\">"+ productName +"</span></li>"); }; }); Then when that writes out there is a remove icon that will remove the item from the ol when clicked. This remove icon has a class of removeIcon which can be seen in the dynamic li above. I have a function that processes the remove call and then does some actions: Code: $('.removeIcon').click(function() { alert("starting"); }); Right now i have the remove action just trying to alert a message that it got called. But it seems that it is not getting into the function. Is there a certain way that i need to access these dynamic li's other then the .click method? I saw this post: Dynamically Inserted DOM Elements are not Clickable using $.click() Where they added .live vs .click but this doesn't seem to work either. Any ideas?

How To Select First Ancestor That Matches A Selector?

- by Zach

General: How can I select the first matching ancestor of an element in jQuery? Example: Take this HTML block <table> <tbody> <tr> <td> <a href="#" class="remove">Remove</a> </td> </tr> <tr> <td> <a href="#" class="remove">Remove</a> </td> </tr> </tbody> </table> I can remove a row in the table by clicking "Remove" using this jQuery code: $('.remove').click(function(){ $(this).parent().parent().hide(); return false; }); This works, but it's pretty fragile. If someone puts the <a> into a <div>, for example, it would break. Is there a selector syntax in jQuery that follows this logic: "Here's an element, now find the closest ancestor that matches some selection criteria and return it" Thanks

Do I need afxres.h, if I am not using MFC? How do I remove it from the .RC script?

- by Cheeso

I don't know RC scripts. I want to include Product version, File version, etc. metadata into a DLL I'm building. I'm using an .rc file to do that. The build is makefile driven. I'm following along with an example .rc scrpit I found. The template .rc file includes afxres.h , but I don't think I need that. But if I just remove it I get a bunch of compile errors. What does a basic, non-MFC RC script look like? Can I remove all the stuff like this: ///////////////////////////////////////////////////////////////////////////// // English (U.S.) resources #if !defined(AFX_RESOURCE_DLL) || defined(AFX_TARG_ENU) #ifdef _WIN32 LANGUAGE LANG_ENGLISH, SUBLANG_ENGLISH_US #pragma code_page(1252) #endif //_WIN32 ....

fedora12, yum not releasing "lock" after performing an action

- by James.Elsey

Hello, This problem has been occurring quite frequently recently and I can't seem to find a way of preventing it. Whenever I perform an action with yum such as to install or remove software, it appears to execute successfully but then I'm unable to move onto the next yum command For example, I executed yum remove skype, it appeared to remove ok, but next when I try to yum search skype it appears that yum is still processing, and I have to manually kill that process via kill 1234 (or whatever the PID is) My output is as follows [root@nevada james]# yum remove skype Loaded plugins: presto, refresh-packagekit Setting up Remove Process Resolving Dependencies --> Running transaction check ---> Package skype.i586 0:2.1.0.47-fc10 set to be erased --> Finished Dependency Resolution Dependencies Resolved ================================================================================ Package Arch Version Repository Size ================================================================================ Removing: skype i586 2.1.0.47-fc10 installed 24 M Transaction Summary ================================================================================ Remove 1 Package(s) Reinstall 0 Package(s) Downgrade 0 Package(s) Is this ok [y/N]: y Downloading Packages: Running rpm_check_debug Running Transaction Test Finished Transaction Test Transaction Test Succeeded Running Transaction Erasing : skype-2.1.0.47-fc10.i586 1/1 Removed: skype.i586 0:2.1.0.47-fc10 Complete!

How to get a safecontrol entry into manifest.xml with WSPBuilder project

- by andrew

Upon taking the default sharepoint master page for MySite, making some changes, and making a wsp out of it with WSPBuilder, I come to these errors in my logs: http://spoint/MySite/%5Fcatalogs/masterpage/MySite.master - An unexpected error has been encountered in this Web Part. Error: The control with virtual path '_controltemplates/Welcome.ascx' is not in the safe controls list for web at URL 'http://spoint/MySite'., Source: [UnsafeControlException: The control with virtual path '_controltemplates/Welcome.ascx' is not in the safe controls list for web at URL 'http://spoint/MySite' (stack trace omitted) http://spoint/MySite/%5Fcatalogs/masterpage/MySite.master - An unexpected error has been encountered in this Web Part.

And I guess I want to do this via the manifest.xml. But I do not see how to make WSPBuilder do this.

PropertyGrid PaintValue problem: How to remove (and paint outside) the standard rectangle?

- by Pedery

This might be a straightforward question, even though I haven't found an easy solution to it: I've implemented my custom UITypeEditor with the sole purpose of adding a PaintValue to bools. For the sake of the discussion, let's assume that PaintValue will either paint a checked or unchecked radiobutton. Question 1: Now, here's the problem: It seems like PaintValue automatically inserts a 20x13px rectangle after all paint code has completed. Naturally, a radiobutton inside a black rectangle is ugly. Can I easily instruct or override this rectagle not to be painted? Question 2: In this respect, is it possible to paint on top of the propertygrid's native look - meaning could I paint something in order to obscure (part of) the black line separating two grid cells vertically? The purpose of doing this would be to indicate that two values were linked, like constrained width/height to an aspect ratio.

jQuery UI modal dialog box and the close button upper right: how to remove it.

- by tahdhaze09

I need to kill the close 'x' button at the top of the dialog box. I have a modal that opens with an OK button that redirects to the site. The site behind the modal is in an iframe. When the user agrees to the statement in the dialog box and clicks the 'OK' button, it redirects to the site that is outside the iframe. If the user clicks on the 'x', it goes to the iframe site, which I do not want to have happen. I need the modal to work as a one-way to the site it goes to. It basically forces the user to accept the user agreement. I would post code, but its an intranet site. Thanks everyone for your help!

How do you remove a site from Sharepoint Designer?

- by xpda

I would like to use Sharepoint Designer 2007 as an html editor. I have a web site with a lot of files in a folder on my hard drive. I do not want Sharepoint Designer to make a web site out of this. I just want to use Sharepoint Designer to edit the html files, locally. If I ever make a mistake and click on a tool for Sites, such as summary or report, Sharepoint Designer will decide that my folder is now a web site. From that point on, Sharepoint Designer is painfully slow whenever I open a file contained in the folder that Sharepoint decided is my web site, instead of being instantaneous like it was before. I can resolve this situation by renaming the folder containing my web site -- everything gets fast again. I can also fix it by uninstalling and reinstalling Sharepoint Designer. Neither of these is a good solution. Is there a place in Sharepoint Designer, or in application data or the registry that I can kill off the Sharepoint Designer web site that's associated with a folder on my hard drive?

ASP.NET MVC hosting problem, routing, handlers and modules

- by johnabs

Hi, This is one of them again, hosting with fasthosts. I recently purchased a windows developer package from them. When I tried to deploy my ASP.NET 3.5 MVC project, which was working fine with the same host on a reseller account, it is not working. The reason to move from reseller to a normal Windows Developer package is, the MS-SQL server database is too expensive in a reseller account, strange! I contact them, and they are saying they upgraded the control panel. The technical support said, I need to disable the Modules and Handlers from the web.config file. Also I need to deploy them as .dll files. I am not sure how to do that. The website is partially working now. I think the problem is now with the routing. I have not deployed any .dlls apart from the System.Web.Mvc.dll, System.Web.Routing.dll and System.Web.Abstractions.dll. I have not got a clue on how to deploy the Modules and Handlers. The code that I commented on the web.config file is as follows.  Anybody got any ideas please. Thank you for your time.

However, when I start up Eclipse, it keeps popping-up a dialog reminding me that I have not established the Adroid device settings. How can I make it stop -- without restarting the workspace?

Does Python doctest remove the need for unit-tests?

- by daniel

Hi all, A fellow developer on a project I am on believes that doctests are as good as unit-tests, and that if a piece of code is doctested, it does not need to be unit-tested. I do not believe this to be the case. Can anyone provide some solid, ideally cited, examples either for or against the argument that doctests do not replace the need for unit-tests? Thank you -Daniel
