• Default values on arguments in C functions and function overloading in C

  - by inquam

  Converting a C++ lib to ANSI C and it seems like though ANSI C doesn't support default values for function variables or am I mistaken? What I want is something like int funcName(int foo, bar* = NULL); Also, is function overloading possible in ANSI C? Would need const char* foo_property(foo_t* /* this */, int /* property_number*/); const char* foo_property(foo_t* /* this */, const char* /* key */, int /* iter */); Could of course just name them differently but being used to C++ I kinda used to function overloading.

• Why is scp not overwriting my destination file?

  - by Noli

  I'm trying to back up a file via the command scp /tmp/backup.tar.gz hostname:/home/user/backup.tar.gz When I run it, the scp progress bar shows up and it looks like its transferring the file, however when I log into the destination server to check the file, the timestamp and filesize haven't changed from the older version, so it looks like scp didn't overwrite the old file at all. It only sees to work when I manually delete the file from the destination server. I'm running ubuntu, and this is happening on two servers: one cygwin ssh, and one fedora core 3. Anyone have any idea why this is happening? I thought scp would ONLY overwrite existing files.. Thanks

• jquery slideUp() and slideDown() problems

  - by nhoss2

  Hello, I am very crap at jquery, and im having some trouble with the slideUp() and slideDown() animations. I have been working on a vCard design similar to tim van damme's site. here is a the link to the design: link. When you click on the portfolio or work button, the text or image appears first before the div finishes sliding down. I would like the div to slide down first and then show the text... This currently works when you click on the contact button or the home button on the top navigation bar, but does not work for the portfolio button and the work button. I have a hunch that this may not even be a jquery problem, and that its just my bad css code, but I have skimmed through the css code, and changed things like z-index, but that hasnt worked.

• .NET MVC - Storing database result during single page result?

  - by ropstah

  Fairly simple issue which is solved in PHP by using a static variable. private static $pages; public function Pages() { if($pages == null) { $pages = new PageCollection(); $pages->findAll(); } } Everywhere in my code I use Pages()::someFindFunction() to make sure the results are fetched only once, and I use that same collection. I want the same in my .NET MVC application: use something like: <%=MySite.Pages.findById(1).Title%> In the code below, if I use a private variable, or if I use a public class with shared variables (doesn't matter) they are both persisted during the entire application. I want them to load the same way PHP does, once per request. Now where do I store the .NET equivalent of private static $pages, so that the code below works? //what to do with $pages?? Public Module MySite Public Function Pages() As PageCollection If $pages Is Nothing Then $pages.loadAll() End If Return $pages End Function End Module

• UIView animation doesn't work first time

  - by BobC

  Hello everybody, I have a seachButton in the navigation bar which upon hitting calls following method: - (IBAction)search:(id)sender { if (nil == searchViewController) searchViewController = [[SearchViewController alloc] initWithNibName:@"SearchViewController" bundle:nil]; searchViewController.view.backgroundColor = [UIColor clearColor]; [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:1.0]; [UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:searchViewController.view cache:NO]; [self.view addSubview:searchViewController.view]; [UIView commitAnimations]; } It should load SearchViewController.xib which contains a view with UISearchBar and two buttons. When I call the search method for the first time, the view appears very quickly with some weird animation, when I call it again, the animation is alright. Does anyone have a clue what could be wrong?

• Panel widget overlapping other contents in android

  - by walker

  I'm trying to utilize the Panel widget introduced in android-misc-widgets. It's been good so far. Now the problem is the sliding panel overlaps my top menu bar. For clarification look at the following screenshots. This is when I open panel using drag gesture (no problem here): This is when I open the panel with a single tap (look at the icons overlapping the top menu): There is one other problem, If there is any content inside the activity, opening the panel pushes that content out of the screen!

• How to set the default page for a .CHM file in HTML Help Workshop?

  - by mengchew0113

  When I open the help (.chm) application, I could see table of contents. By default, the first entry in the file is selected, however I couldn't see the corresponding page data. Instead, I see "This program cannot display the web page" (the default error message that comes in IE7).The page is displayed only when I click on any of the contents on the left side. Is there a way of showing the page by default without clicking on the entry? The following code is the .hhp file.

The newGame, startLevel, and update functions should be your // first priority since they're all involved in displaying the initial state // of the game board. // // Next, work on putting together the control panel for the game so that you // can begin to interact with it. Your next goal should be to get the move // function working so that everything else can be testable. Note that all nine // of the movement buttons (including the pass button) should call the move // function when they are clicked, just with different parameters. // // All the remaining functions can be completed in pretty much any order, and // you'll see the game gradually improve as you write the functions. // // Just remember to keep your cool when writing this program. There are a // bunch of functions to write, but as long as you stay focused on the function // you're writing, each individual part is not that hard. // These variables specify the number of rows and columns in the game board. // Use these variables instead of hard coding the number of rows and columns // in your loops, etc. // i.e. Write: // for(i = 0; i < NUM_ROWS; i++) ... // not: // for(i = 0; i < 15; i++) ... var NUM_ROWS = 15; var NUM_COLS = 25; // Scene is arguably the most important variable in this whole program. It // should be set up as a two-dimensional array (with NUM_ROWS rows and // NUM_COLS columns). This represents the game board, with the scene[i][j] // representing what's in row i, column j. In particular, the entries should // be: // // "." for empty space // "R" for a robot // "S" for a scrap pile // "H" for the hero var scene; // These variables represent the row and column of the hero's location, // respectively. These are more of a conveniece so you don't have to search // for the "H" in the scene array when you need to know where the hero is. var heroRow; var heroCol; // These variables keep track of various aspects of the gameplay. // score is just the number of robots destroyed. // screwdrivers is the number of sonic screwdriver charges left. // fastTeleports is the number of fast teleports remaining. // level is the current level number. // Be sure to reset all of these when a new game starts, and update them at the // appropriate times. var score; var screwdrivers; var fastTeleports; var level; // This function should use a sonic screwdriver if there are still charges // left. The sonic screwdriver turns any robot that is in one of the eight // squares immediately adjacent to the hero into scrap. If there are no charges // left, then this function should instead pop up a dialog box with the message // "Out of sonic screwdrivers!". As with any function that alters the game's // state, this function should call the update function when it has finished. // // Your "Sonic Screwdriver" button should call this function directly. function screwdriver() { // WRITE THIS FUNCTION } // This function should move the hero to a randomly selected location if there // are still fast teleports left. This function MUST NOT move the hero on to // a square that is already occupied by a robot or a scrap pile, although it // can move the hero next to a robot.

• Good conventions for embedding schema of a flat file

  - by Ville Koskinen

  We receive lots of data as flat files: delimitted or just fixed length records. It's sometimes hard to find out what the files actually contain. Are there any well established practices for embedding the schema of the file to the beginning or the end of a file to make the file self-explanatory? Just to get an idea, imagine something like this: <data name=test records=2 type=fixed> <field name=foo start=0 length=2 type=numeric> <field name=bar start=2 length=4 type=text> </data> 11test 12ing We would parse the xml in the beginning and use it for reading the records.

• how to avoid 'out of memory' errors when programmatically generating a lot of nodes in drupal?

  - by sprugman

  I'm creating about 150 nodes programmatically and running into 'out of memory' errors when doing it all in a single request. (I have a menu callback that generates the nodes and calls node_save() on them.) Example: for($i=0; $i<150; $i++) { $node = new stdClass(); $node->title="Foo $i"; $node->field_myfield[0]['value'] = "Bar $i"; ... node_save($node); } I've heard of BatchAPI, but never used it. Is that the right tool to get around this? The docs talk about timeouts, but not memory issues. Is there something simpler that I might be missing?

• Get #part in URL with PHP/Symfony

  - by fesja

  Hi, I'm working with Symfony 1.2. I've a view with a list of objects. I can order them, filter them by category, or moving to the next page (there is pagination). Everything is done with AJAX, so I don't have to load all the page again. What I want to achieve is to have http://urltopage#page=1&order=title&cats=1,2 for example; so the new page is saved in the browser history, and he can paste it to another web. I haven't found a way to get the #part. I know that's only for the browser but I can't believe I can't get through PHP. I'm sure there is a simple solution I'm missing... thanks a lot!

• What is the best way to implement an object cache with Entity Framework?

  - by Harshal

  Say I have a table of "BlogPosts" in a database and i want to be able to cache the ones that were retrieved already in memory, for further reads, I can just use a standard hashtable type memory cache like System.Web.Caching.Cache, but if i then need to update a property on one of these blog posts e.g. blogPost.Title and update the record in DB, i cannot do this without fetching it again from database as the Entity Framework context used to fetch this record when it was loaded into my cache is already disposed? How do I write code so that I am getting an object from my cache, updating one property and just calling the SaveChanges method without incurring an extra read.

• Trouble defining a variable in PHP?

  - by Jake

  Alright, so a content page uses this: $tab = "Friends"; $title = "User Profile"; include '(the header file, with nav)'; And the header page has the code: if ($tab == "Friends") { echo '<li id="current">'; } else { echo '<li>'; } The problem is, that the if $tab == Friends condition is never activated, and no other variables are carried from the the content page, to the header page. Does anyone know what I'm doing wrong? Update: Alright, the problem seemed to disappear when I used ../scripts/filename.php, and only occurred when I used a full URL? Any ideas why?

• Simulating C-style for loops in python

  - by YGA

  (even the title of this is going to cause flames, I realize) Python made the deliberate design choice to have the for loop use explicit iterables, with the benefit of considerably simplified code in most cases. However, sometimes it is quite a pain to construct an iterable if your test case and update function are complicated, and so I find myself writing the following while loops: val = START_VAL while <awkward/complicated test case>: # do stuff ... val = <awkward/complicated update> The problem with this is that the update is at the bottom of the while block, meaning that if I want to have a continue embedded somewhere in it I have to: use duplicate code for the complicated/awkard update, AND run the risk of forgetting it and having my code infinite loop I could go the route of hand-rolling a complicated iterator: def complicated_iterator(val): while <awkward/complicated test case>: yeild val val = <awkward/complicated update> for val in complicated_iterator(start_val): if <random check>: continue # no issues here # do stuff This strikes me as waaaaay too verbose and complicated. Do folks in stack overflow have a simpler suggestion?

• Weird background offset of UIToolbar when in formSheet.

  - by Mike A

  As you can see in the pic, the buttons from the toolbar on the right align perfectly with the segmented control on the left. They are displayed on the navigation bar. For some reason though, the background of the toolbar seems to be offset 1px to the bottom. What is especially weird, is this exact same view controller, in fullScreen or even pageSheet, displays everything properly. Segmented control is being allocated: UISegmentedControl* segmentControl = [[UISegmentedControl alloc] initWithFrame:CGRectMake(0,0,300,30)]; Toolbar is being allocated: UIToolbar* toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 100,44)]; I've spent hours trying to fix this, it's driving me crazy.

• Get status of servlet request before the response is returned

  - by Alex

  Good evening, I am in the process of writing a Java Servlet (Struts 2, Tomcat, JSP etc) which is capable of doing some fairly complex simulations. These can take up to 2 minutes to complete on the and will return a graph of the results. It is trivial to calculate the percentage of the simulation completed because the process works by repeating the same calculations 1000s of times. I would be interested to know if anyone has ever tried to use client side technology to provide any estimate of the percentage complete. I.e query the servlet processing to get the number of cycles completed at various point throughout the simulation. This could then be displayed as a bar in the client browser. Any thoughts, advice, resources would be much appreciated. Thanks, Alex

• How can I simulate an anchor click via jquery?

  I have a problem with faking an anchor click via jQuery: Why does my thickbox appear the first time I click on the input button, but not the second or third time? Here is my code: <input onclick="$('#thickboxId').click();" type="button" value="Click me"> <a id="thickboxId" href="myScript.php" class="thickbox" title="">Link</a> It does always work when I click directly on the link, but not if I try to activate the thickbox via the input button. This is in FF. For Chrome it seems to work every time. Any hints?

• Strange routing

  - by astropanic

  How I can setup my rails app to respond to such urls: http://mydomain.com/white-halogene-lamp http://mydomain.com/children-lamps http://mydomain.com/contact-form The first one should link to my products controller, and show my product with this name The second one should link to my categories controller, and show the category with this name The third one should link to my sites controller, and show the site with this title. All three models (product, category, site) have a method to_seo, giving the mentioned above urls (after the slash) I know it's not the restful way, but please don't disuss here, it is wrong approach or not, that's not the question. The question is how to accomplish this weird routing ? I know we have catch all routes, but how I can tell rails to use different controllers on different urls in the catch all route ? Or have You an better idea ? I would avoid redirects to other urls.

• Visual Studio Unit Tests : dll is not trusted

  I'm struggling getting some unit tests running and wondering if anyone might have anything insightful. The setup is that we've got a bunch of referenced DLL's on a server and when I try and execute I get the old Test Run deployment issue: The location of the file or directory 'c:\source\ProjectName\bin\debug\3rdPartyLibrary.dll' is not trusted. I've tried the old caspol command: caspol -m -ag 1.2 -url file:\server\binaries* FullTrust Which seems to work for everything bar one DLL. I'm currently having to manually change the permissions everytime I do a build of the test project, which is a pain. Anyone have any suggestions? Running a Win7 64bit OS btw.

• Sorting Table Cells based on data from NSArray

  Hi, I have an NSArray which contains information from an RSS feed on dogs, such as [dog types], [dog age] and [dog size]. At the moment my UITableView simply displays each cell on each dog and within the cell lists [dog types], [dog age] and [dog size]. I want to be able to allow users of my app to "sort" this data based on the dog name, dog size or dog age when they press a UIButton in the top nav-bar. I'm struggling to work out how to filter the UITableView based on these factors, so any help is appreciated. Thanks.

• C# ASP.Net The type or namespace name 'iAnywhere' could not be found

  - by Louis Russell

  Morning all, I know that this sounds like a simple referencing problem from the title this is becoming a nightmare! I have a code class that uses the "iAnywhere.Data.AsaClient.dll". This Dll is referenced in the project and in the code class I have added this dll in the Using section. Everything seems fine at build with no errors at all but when I go to run the application it comes up with the following Compilation Error: Compiler Error Message: CS0246: The type or namespace name 'iAnywhere' could not be found (are you missing a using directive or an assembly reference?) The line that the Error points to this line in the class: using iAnywhere.Data.AsaClient; I have set the dll to copy local and it makes no difference, the Dll is installed on my PC so is in the GAC, I use this Dll with many other C# projects and have no problems. I have scoured Google looking for an answer and haven't found anything that points me to an answer to my problem. Any help would be brilliant!
