• C# How to Present Such Question?

  - by ikurtz

  greetings! i have a C# game program that im developing. it uses sound samples and winsock. when i test run the game most of the audio works fine but from time to time if it is multiple samples being played sequentially the application form shakes a little bit and then goes back to its old position. how do i go about debugging this or present it to you folks in a manageable manner? im sure no one is going to want the whole app code in fear of virus attacks. please guide me.. thanking you. EDIT: i have not been able to pin down any code section that produces this result. it just does and i cannot explain it. EDIT: no the x/y position are not changing. the window like shakes around a few pixels and then goes back to the position were it was before the shake.

• Select Box not filling properly in rails

  - by CaptnCraig

  I am creating a select box for a form using this in _form.html.erb <%= f.select(:category_id,options_for_select(@cats)) %> @cats is an array created in my controller like this: @cats = [] categories.each do |c| @cats.push([c.full_name,c.id]) end The select box is properly filled, and the selected foreign key is even properly saved to the database. The problem is, when I come back in my edit action, the select box is moved back to the first item in the list, not the one corresponding to category_id. Reading the documentation it seems like this should just magically work. How do I get it to select the proper value?

• jquery slider breaks on page refrsh

  - by Nik

  I have a jquery content slider on a site I'm developing. I am having a strange problem that seems to be across all browsers and that is the slider slides the wrong distance if the page is refreshed via the refresh button. To re-create the problem please follow these steps - click this link http://www.aus-media.com/dev/site_BYS/index.html then click on the 'About Bikram Yoga' menu item at the bottom. Click on the 'more' and 'back' tabs on this page and you will notice it works fine. Then refresh the page by clicking the refresh button and try the more and back buttons again. I'm a bit of a javascript newby so I'm lost to why it's doing this. Any help would be great. Thanks Nik

• How can a student programmer improve his teamwork skill?

  - by xiao

  I am a student right now. Recently, I am working in a project as a leader with three other students. Due to the lack of experience, our project is progressing slowly and our members are frustrated. They do not feel sense of accomplishment in the project. I am pressured and frustrated, too. But as a team leader, I think I need to push them. But I do not know how to do. Do I help them solve coding problem or just encouragement? But if I pay too much attention on it, it would slow down my own progress. It is a not technical question, but it is very common in software development. I hope veteran programmers would give me some suggestions. Thanks!

• Strange PHP reference bug

  - by Roland Soós

  Hello, I have a really strange bug with my PHP code. I have a recursive code which build up a menu tree with object and one of my customers server can't make it work. Contructor: function Menu(&$menus, &$keys , &$parent, &$menu){ ... if($keys === NULL){ $keys = array_keys($menus); } ... for($x = 0; $x < count($keys); $x++) { var_dump($keys); $menu = $menus[$keys[$x]]; var_dump($keys); if($this->id == $menu->pid){ $keys[$x] = NULL; $this->submenus[] = new Menu($menus, $keys, $this, $menu); } } First var_dump give me back the array, the second give back the first element of $menus. Do you have any idea what causes this? PHP version 5.2.3

• What is the String 'volumeName' argument of MediaStore.Audio.Playlists.Members.getContentUri referri

  - by Brett

  I am wanting to query the members of a given playlist. I have the correct playlist id, and want to use a managedQuery() to look at the playlist members in question. What I have is this: private String [] columns = { MediaStore.Audio.Playlists.Members.PLAYLIST_ID, MediaStore.Audio.Playlists.Members.TITLE, }; Uri membersUri = MediaStore.Audio.Playlists.Members.getContentUri(volume, playlistId); Cursor tCursor = managedQuery(membersUri, columns, null, null, null); I don't know what the volume argument needs to be. I've tried this: MediaStore.Audio.Playlists.EXTERNAL_CONTENT_URI.toString() for the "volume" argument. That gives me back a valid content URI that looks like: content://media/external/audio/playlists/2/members However, my cursor comes back null. I probably am way off base -- I know what I want to do is very simple.

• Can WinRT really be used at just the boundaries?

  - by Bret Kuhns

  Microsoft (chiefly, Herb Sutter) recommends when using WinRT with C++/CX to keep WinRT at the boundaries of the application and keep the core of the application written in standard ISO C++. I've been writing an application which I would like to leave portable, so my core functionality was written in standard C++, and I am now attempting to write a Metro-style front end for it using C++/CX. I've had a bit of a problem with this approach, however. For example, if I want to push a vector of user-defined C++ types to a XAML ListView control, I have to wrap my user-defined type in a WinRT ref/value type for it to be stored in a Vector^. With this approach, I'm inevitably left with wrapping a large portion of my C++ classes with WinRT classes. This is the first time I've tried to write a portable native application in C++. Is it really practical to keep WinRT along the boundaries like this? How else could this type of portable core with a platform-specific boundary be handled?

• How to map IEnumerable<SelectListItem> to IList<> for ListBox

  - by Superhuman

  I have two classes. Class1 and Class2. public class Class1{ ... public virtual IList<Class2> Class2s{get;set;} ... } public class Class2{ ... public virtual IList<Class1> Class1s{get;set;} ... } The view contains <%=Html.ListBox("Class2s", ViewData.Model.Class2s.Select( x => new SelectListItem { Text = x.Name, Value = x.Id.ToString(), Selected = ViewData.Model.Class1.Class2s.Any(y => y.Id == x.Id) }) They have many to many mapping. I have a ListBox in Class1 view which displays Class2. How to map the output of the ListBox back to IList Class2s property of Class1? I am able to display the values in the ListBox but unable to map back the SelectListItem to IList.

• Using custom request and custom redirect with Contact Form 7

  - by Scott B

  I have several sites that I want to link back to the main site which hosts the contact form (using contact form 7). I would like to capture the request parameter "site-url" on incoming links to the contact form. Then when the user submits the form, I would like to redirect them back to the site specified in the site-url. Any ideas if this is possible with contact form 7? I would also like to add a special field in the contact form which would insert the site-url into the email that i get so that I know which site they were referred from.

• Alternatives to ImageMagick for PDF downsizing

  - by Craig Coston

  Having an issue with some PDF files not displaying properly in our iPad app. I have come to the conclusion that we are needing to standardize by "converting" PDF to PDF. I have successfully processed this using ImageMagick to convert the PDF to PNG (resized), and then pushing the PNG(s) back into a PDF. However, something within ImageMagick is making photos within PDFs display wrong. Same issue just converting a JPG or other graphic to PDF in ImageMagick. I solved that by taking the output of the converted ImageMagick file and converting it again using GD to PNG, then pushing it through our PDF converter. So my question is this: What other PHP workflows would work with this, other than using ImageMagick for the conversion back to PDF? We are not opposed to a paid solution, we just need something that works. Our server runs centOS.

• Bitbucket and a small development house

  - by Marlon

  I am in the process of finally rolling Mercurial as our version control system at work. This is a huge deal for everyone as, shockingly, they have never used a VCS. After months of putting the bug in management's ears, they finally saw the light and now realise how much better it is than working with a network of shared folders! In the process of rolling this out, I am thinking of different strategies to manage our stuff and I am leaning towards using Bitbucket as our "central" repository. The projects in Bitbucket will solely be private projects and everyone will push and pull from there. I am open to different suggestions, but has anyone got a similar setup? If so, what caveats have you encountered?

• What are the most important concepts to understand for "fluency in developer English"?

  - by Edward Tanguay

  In April, I'm going to be giving a talk called **English 2.0 - Understanding the Language of Developers" to a group of English teachers. The purpose is in two hours to give them a quick background in key concepts so that they can better understand developer blogs and podcasts and are able to ask better questions when talking to developers. What do you think are the most important concepts to understand, concepts that developers take for granted but the general public is not familiar with? Here are a few ideas: version control abstractions pub/sub push vs. pull debugging modularity three-tier architecture class/object "spaghetti code" vs. OOP exception throwing crowd sourcing refactoring the cloud DRY - don't repeat yourself client/server unit testing designer/developer

• stringstream problem - vector iterator not dereferencable

  - by andreas

  Hello I've got a problem with the following code snippet. It is related to the stringstream "stringstream css(cv.back())" bit. If it is commented out the program will run ok. It is really weird, as I keep getting it in some of my programs, but if I just create a console project the code will run fine. In some of my Win32 programs it will and in some it won't (then it will return "vector iterator not dereferencable" but it will compile just fine). Any ideas at all would be really appreciated. Thanks! vector<double> cRes(2); vector<double> pRes(2); int readTimeVects2(vector<double> &cRes, vector<double> &pRes){ string segments; vector<string> cv, pv, chv, phv; ifstream cin("cm.txt"); ifstream pin("pw.txt"); ifstream chin("hm.txt"); ifstream phin("hw.txt"); while (getline(cin,segments,'\t')) { cv.push_back(segments); } while (getline(pin,segments,'\t')) { pv.push_back(segments); } while (getline(chin,segments,'\t')) { chv.push_back(segments); } while (getline(phin,segments,'\t')) { phv.push_back(segments); } cin.close(); pin.close(); chin.close(); phin.close(); stringstream phss(phv.front()); phss >> pRes[0]; phss.clear(); stringstream chss(chv.front()); chss >> cRes[0]; chss.clear(); stringstream pss(pv.back()); pss >> pRes[1]; pss.clear(); stringstream css(cv.back()); css >> cRes[1]; css.clear(); return 0; }

• problem with adding tool bar to UITableView

  - by chnet

  I'm writing a Navigation-Based iPhone app, and I'd like to have a UIToolBar docked at the bottom of my screen, with a UITableView scrolling between the tool bar and the navigation bar. I used [[self navigationController] setToolbarHidden:NO] and - (void)setToolbarItems:(NSArray *)toolbarItems animated:(BOOL)animated to set the UIToolBar. UIToolBar correctly shows in current view. If I drill down into a detail view using the button on navigation bar, i cannot return back to previous view. Before I add the tool bar, it can return back. I am wondering is there anything else should be noted when use UIToolbar?

• Microsoft BizTalk Server vNext (after 2009 R2) - Feature Request

  - by Saravana Kumar

  All, This post is not a question; it’s more of asking for feed back and future request. The product team is always looking for feed back to facilitate the future direction of the product. Some of us as BizTalk Server MVP’s/partners get that privilege to work with the product team closely to give our feedback regularly based on our real world experience. But I believe there is a much wider BizTalk community out there working on closed door project that tests the strength of the product to extreme levels. I would like those passionate people to come forward and put their feature request. Let’s use the power of StackOverflow to help us here. We can vote up and down on each feature request, and see what's going to top the chart. I hope this will be a useful exercise. Updated 24th Feb: If you got more than one request, please post it as separate answers. So, its easy to vote against them.

• A couple questions using fwrite/fread with data structures

  - by Nazgulled

  Hi, I'm using fwrite() and fread() for the first time to write some data structures to disk and I have a couple of questions about best practices and proper ways of doing things. What I'm writing to disk (so I can later read it back) is all user profiles inserted in a Graph structure. Each graph vertex is of the following type: typedef struct sUserProfile { char name[NAME_SZ]; char address[ADDRESS_SZ]; int socialNumber; char password[PASSWORD_SZ]; HashTable *mailbox; short msgCount; } UserProfile; And this is how I'm currently writing all the profiles to disk: void ioWriteNetworkState(SocialNetwork *social) { Vertex *currPtr = social->usersNetwork->vertices; UserProfile *user; FILE *fp = fopen("save/profiles.dat", "w"); if(!fp) { perror("fopen"); exit(EXIT_FAILURE); } fwrite(&(social->usersCount), sizeof(int), 1, fp); while(currPtr) { user = (UserProfile*)currPtr->value; fwrite(&(user->socialNumber), sizeof(int), 1, fp); fwrite(user->name, sizeof(char)*strlen(user->name), 1, fp); fwrite(user->address, sizeof(char)*strlen(user->address), 1, fp); fwrite(user->password, sizeof(char)*strlen(user->password), 1, fp); fwrite(&(user->msgCount), sizeof(short), 1, fp); break; currPtr = currPtr->next; } fclose(fp); } Notes: The first fwrite() you see will write the total user count in the graph so I know how much data I need to read back. The break is there for testing purposes. There's thousands of users and I'm still experimenting with the code. My questions: After reading this I decided to use fwrite() on each element instead of writing the whole structure. I also avoid writing the pointer to to the mailbox as I don't need to save that pointer. So, is this the way to go? Multiple fwrite()'s instead of a global one for the whole structure? Isn't that slower? How do I read back this content? I know I have to use fread() but I don't know the size of the strings, cause I used strlen() to write them. I could write the output of strlen() before writing the string, but is there any better way without extra writes?

• There is any reason for which a delete method/field/function refactoring doesn't exist?

  - by raisercostin

  An operation in an interface is obsolete so I decided to delete it. It seems that there is no automatic support for such a "refactoring". For me is a refactoring operation since the behavior of the code will be preserved since nobody(tests, client apis) will notice that the operation was removed. In eclipse, in java code, on an method in an interface I have the following options: rename, move, change method signature, inline, extract interface, extract superclass, use supertype when possible, pull up, push down, introduce parameter objet, introduce indirection, generate declared type. There is any reason for which a delete method/field/function refactoring doesn't exist?

• GAC behaviour

  - by pkolodziej

  I put signed dll into GAC. I delete this dll from folder where other applications could reach it. I try to run client app, which used that dll. Dll is immidiately put back to the original folder. How does it happen? I am guessing that GAC is monitoring folder and when it detects that dll is missing it puts the latest version back to the folder where other applications could reach it. If I am correct please tell me if GAC will automatically backup dll again if it will be rebuild.

• WPF ComboBox SelectedItem - change to previous value

  - by Taylor

  Hello, I have a ComboBox that has the SelectedItem bound to the ViewModel. <ComboBox SelectedItem="{Binding SelItem, Mode=TwoWay}" ItemsSource="{Binding MyItems}"> When the user selects a new Item in the View ComboBox, I want to display a prompt and verify that they want to make the change. In the SetItem Property setter in the View Model, I display a Dialog to confirm the selection. When they say yes, it works fine. My problem is, when the user clicks on "No" I am not sure who to get the ComboBox to revert back to the previous value. The Property in the ViewModel has the correct older value, however in the View the ComboBox displays the newly Selected Value. I want the user to select an item, confirm they want to go ahead with it, and if they decide not to, I want the ComboBox to revert back to the previous item. How can I accomplish this? Thanks!

• XPathNavigator in Silverlight

  - by vladimir

  I have a code library that makes heavy use of XPathNavigator to parse some specific xml document. The xml document is cross-referenced, meaning that an element can reference another which has not yet been encountered during parsing: <ElementA ...> <DependentElementX id="1234"> </ElementA> <ElementX id="1234" .../> The document doesn't really look like this, but the point is that 1) there is an xml schema that enforces the overall document structure, 2) elements inside the document can reference each other using some IDs, and 3) there is quite a few such cross references between different elements in the document. The document is parsed in two phases. In the first pass I walk through the document XPathDocument doc = ...; XPathNavigator nav = doc.CreateNavigator(); nav.MoveToRoot(); nav.MoveToFirstChild()... and occasionally 'bookmark' the current position (element) in the document using XPathNavigator.Clone() method. This gives me a lightweight instance of an XPathNavigator which I can store somewhere and use later to jump back to a particular place (element) in my document. Once I have enough information collected in the first pass (for example, I have made sure there is indeed an ElementX with an id='1234'), I jump back to saved bookmarks (using those saved XPathNavigators) and complete the parsing. Well, now I'm about to use this library in Silverlight 3.0 and to my horror the XPathNavigator is not in the System.Xml assembly. Questions: 1) Am I missing something obvious (i.e. XPathNavigator does exist in some shape or form, for example in a toolkit or a freeware library)? 2) If I do have to make modifications in the code, what would be the best way to go? Ideally, I would like to make minimal changes, not to rewrite 80% of the code just to be able to use something like XLinq. To resume, in case I have to give up XPathNavigator, all I need is a way to bookmark places in my document and to get back to them so that I can continue to iterate from where I left off. Thanks in advance for any help/ideas.

• How to store character moves (sprite animations)?

  - by Saad

  So I'm thinking about making a small rpg, mainly to test out different design patterns I've been learning about. But the one question that I'm not too sure on how to approach is how to store an array of character moves in the best way possible. So let's say I have arrays of different sprites. This is how I'm thinking about implementing it: array attack = new array (10); array attack2 = new array(5); (loop) //blit some image attack.push(imageInstance); (end loop) Now every time I want the animation I call on attack or attack2; is there a better structure? The problem with this is let's say there are 100 different attacks, and a player can have up to 10 attacks equipped. So how do I tell which attack the user has; should I use a hash map?

• why can't I comment lines in visual mode

  - by Haiyuan Zhang

  I want to comment several lines in my .vimrc, the usual way I do it is :x,ys/^/"/ and x stands for the start line number and y stands for the line number of the last line. I read some post which said in visual mode this task can be done by the following step: 1 Select your lines with VISUAL BLOCK 2 press I to insert before all highlighted lines. 3 type your comment charact , in this case should be " 4 then ESC I fllowed the above steps and met met problems in step 2 . the thing is when I select the lines in Visual mode and press I , vim ( I use version7.2) go back to insert mode and the cursor back to the start of the first line. so if you continue to do the step 3 and step 4, you end up in just inserting " at the start the first line , far from what I want to achieve. so could you point out what's wrong with the recipe ? thanks in advance

• WCF Duplex Interaction with Web Server

  - by Mark Struzinski

  Here is my scenario, and it is causing us a considerable amount of grief at the moment: We have a vendor web service which provides base level telephony functionality. This service has a SOAP api, which we are leveraging to build up a custom UI that is integrated into our in house web apps. The api functions on 2 levels. You make standard client calls into the service to initiate actions, such as Login, Place Call, Hang Up, etc. On a different thread, the service sends events back to the client to alert the user of things that are occurring on the system (agent successfully logged in, call was disconnected, etc). I implemented a WCF service to sit between the web server and the vendor service. This WCF service operates in duplex mode, establishing a 2 way connection with the web server. The web server makes outbound calls to the WCF service, which routes them to the vendor's web service. Events are received back to the WCF service, which passes them onto the web server via a callback channel on the WCF client. As events are received on the web server, they are placed into a hash table with the user's name as the key, and a .NET queue as the value to hold the event. Each event is enqueued to the agent who owns it. On a 2 second interval, the web page polls the web server via an ajax request to get new events for the logged in user. It hits the hash table for the user key, dequeues any events that are present, and serializes them back up to the web page. From there, they are processed in order and appropriate messages are displayed to the user. This implementation performs well in a single user scenario. The second I put more than 1 user on the system, I start getting frequent timeouts with the following CommunicationException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond We are running Windows Server 2008 R2 both servers. Both the web app and WCF service are running on .NET 3.5. The WCF service is running under the net.tcp protocol in duplex mode. The web app is ASP.NET MVC 2. Has anyone dealt with anything like this scenario? Is there a more efficient way (or a widely accepted pattern) to implement this?

• How do I redirect a page in php

  - by user225269

  I'm having difficulties in the making the logout code for php to work. When I click on the logout button, it will go back to the home page, but when I click on the back button in the browser. I can still access the previous page, wherein the user must be logged on to access it. So I'm thinking of redirecting to the login page when the user clicks on the back button on the browser. This is my code, in the home page(where in no user is logged in yet. This page is being called by a logout link on the user page. <? session_start(); session_destroy(); ?> <table width="300" border="0" align="center" cellpadding="0" cellspacing="1" bgcolor="#CCCCCC"> <tr> <form name="form1" method="post" action="checklogin.php"> <td> <table width="100%" border="0" cellpadding="3" cellspacing="1" bgcolor="#FFFFFF"> <tr> <td colspan="3"><strong>Member Login </strong></td> </tr> <tr> <td width="78">Username</td> <td width="6">:</td> <td width="294"><input name="myusername" type="text" id="myusername"></td> </tr> <tr> <td>Password</td> <td>:</td> <td><input name="mypassword" type="text" id="mypassword"></td> </tr> <tr> <td>&nbsp;</td> <td>&nbsp;</td> <td><input type="submit" name="Submit" value="Login"></td> </tr> </table> </td> </form> </tr> </table>
