  • Strlen of MAX 16 chars string using bitwise operators

    - by fabrizioM
    The challenge is to find the fastest way to determine in C/C++ the length of a c-string using bitwise operations in C. char thestring[16]; The c-string has a max size of 16 chars and is inside a buffer If the string is equal to 16 chars doesn't have the null byte at the end. I am sure can be done but didn't got it right yet. I am working on this at the moment, but assuming the string is memcpied on a zero-filled buffer. len = buff[0] != 0x0 + buff[1] != 0x0 + buff[2] != 0x0 + buff[3] != 0x0 + buff[4] != 0x0 + buff[5] != 0x0 + buff[6] != 0x0 + buff[7] != 0x0 + buff[8] != 0x0 + buff[9] != 0x0 + buff[10] != 0x0 + buff[11] != 0x0 + buff[12] != 0x0 + buff[13] != 0x0 + buff[14] != 0x0 + buff[15] != 0x0;

  • moving SDL video surface

    - by runrunraygun
    Does anyone know how to move my SDL.net video surface around the screen programtically? Surface videoContext = Video.SetVideoMode(1024, 768, 32, false, false, false, true, true); var a = System.Windows.Forms.Control.FromHandle(Video.WindowHandle); var b = System.Windows.Forms.NativeWindow.FromHandle(Video.WindowHandle); I can't find any properties in Surface or Video which do the job, and FromHandle is returning Null.

  • MYSQL Fast Insert dependent on flag from a seperate table

    - by Stuart P
    Hi all. For work I'm dealing with a large database (160 million + rows a year, 10 years of data) and have a quandary; A large percentage of the data we upload is null data and I'd like to stop it from being uploaded. The data in question is spatial in nature, so I have one table like so: idLocations (Auto-increment int, PK) X (float) Y (foat) Alwaysignore (Bool) Which is used as a reference in a second table like so: idLocations (Int, PK, "FK") idDates (Int, PK, "FK") DATA1 (float) DATA2 (float) ... DATA7 (float) So, Ideally I'd like to find a method where I can do something like: INSERT INTO tblData(idLocations, idDates, DATA1, ..., DATA7) VALUES (...), ..., (...) WHERE VALUES(idLocations) NOT LIKE (SELECT FROM tblLocation WHERE alwaysignore=TRUE ON DUPLICATE KEY UPDATE DATA1=VALUES(DATA1) So, for my large batch of input data (250 values in a block), ignore the inserts where the idLocations matches an idLocations values flagged with alwaysignore. Anyone have any suggestions? Cheers. -Stuart Other details: Running MySQL on a semi-dedicated machine, MyISAM engine for the tables.

  • Windows API - Beginner help

    - by nXqd
    I try to create a very simple app using windows API. I've done some small apps in console. This is the first time I do with Win32 apps. I've searched and found a document from forgers which is recommended in this site. But I try to write very first line: #include <stdafx.h> #include <windows.h> int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) { MessageBoxW (NULL, "Good bye Cruel World", "Note", MB_OK ); return 0; } But it doesn't work ( erased lines from default project created by VS 2008 and write these lines ) Waiting for your answers :)

  • YouTube API Get all videos uploaded feed

    - by Paul
    Hi Guys, I can't seem to retrieve ALL videos from a particular channel on YouTube, despite the API giving example code that should perform just that. I'm using Java. http://gdata.youtube.com/feeds/api/users/GoogleDevelopers/uploads The above rss feed is the URL they suggest using along with the following sample code.. /*init the list*/ String feedUrl = "http://gdata.youtube.com/feeds/api/users/GoogleDevelopers/uploads"; VideoFeed videoFeeder = null; videoFeeder = serviceobject.getFeed(new URL(feedUrl), VideoFeed.class); Looping this with a for loop suggests 25 entries (as per the RSS). However - the actual number of videos uploaded is significantly larger. (662 at time of writing). My query is how on earth you retrieve everything with the API, not just a subset of the data. Any ideas on where I'm going wrong? Should I be using a different URL? http://www.youtube.com/GoogleDevelopers#g/a

  • UserControl Behaviour on a Windows Form

    - by AK
    Hi, I have a usercontrol UC1 with a combobox and a button. From the constructor, after initializing all the controls, I am populating the combobox with an array of information brought from other class library. I have kept the UC1 on windows form. When I tried to open the form's designer I see some errors and a suggestion to rebuild to fix the errors. After searching over net I found that the logic of populating the combobox is the culprit. I changed the code with an additional check of null and the issue is fixed now. My question is, how am i able to see the same usercontrol seperatly in designer view, but not when i placed the UC1 on a form and trying to see the designer view for the form? The same combobox populating logic should affect the drawing of UC1 when I try to see it in designer view right? Thanks, AK.

  • adding tabs to tabcontrol from inside usercontrol

    - by Jakob
    How can I add tabs to a tabcontrol that exists in one usercontrol from another usercontrol that is contained within a tab itself?? Can I do it without passing in the tabcontrol as a parameter in the constructor, perhaps via some static global method? I've tried public static ObservableTabCollection FindCollectionFromUC(this DependencyObject depObject) { bool loop = true; var parent = (VisualTreeHelper.GetParent(depObject) as FrameworkElement); while (loop) { if (parent.GetType() is TabControl) { loop = false; return ((ObservableTabCollection)((TabControl)parent).ItemsSource); } } return null; } but this is just an infinite loop

  • Refresh/Reset View

    - by Jay
    Hi, I'm using MVP in WPF and I came across a design doubt and I would to get your opinion on this: At some point I need to refresh my view and perform the same initial queries, like when the view was loading. The view's DataContext is my presenter and I have a couple of collections and other variables that are bound to the view. When I need to refresh the view, I'm clearing the collections and the variables and setting the DataContext to null. After that I fetch new data, populate the collections and set the DataContext. Is this the best way to achieve this? The issue with this, is that i'm affraid that when my app grows bigger I forget to reset some variable...the ideal would be to reload the view again in some way without having to worry with the variables I have. Best regards.

  • NSNumberFormatter weirdness with NSNumberFormatterPercentStyle

    - by rein
    Hi, I need to parse some text in a UITextField and turn it into a percentage. Ideally, I'd like the user to either type something like 12 or 12% into the text field and have that be parsed into a number as a percentage. Here's what's weird. The number formatter seems to not like 12 and seems to divide 12% by 10000 instead of 100: NSNumberFormatter *formatter = [[[NSNumberFormatter alloc] init] autorelease]; [formatter setNumberStyle:NSNumberFormatterPercentStyle]; NSNumber *n1 = [formatter numberFromString:@"12"]; NSNumber *n2 = [formatter numberFromString:@"12%"]; NSLog(@"n1 = %@", n1); // n1 = (null) NSLog(@"n2 = %@", n2); // n2 = 0.0012 How do I get the formatter to return 0.12 as expected? EDIT: it seems to only happen if the formatter fails first. If the formatter does not fail it returns 0.12 as expected. Strange.

    - by Jova
    I'm changing my project from working with Linq-to-SQL to working with Entity Framework. I have some extention methods that extend the classes created by LINQ and I'm wondering how to change them to work with the entities instead Here's an example. public static int GetPublishedArticlesCount(this Table<Article> source) { return GetPublishedArticles(source.Context as DataContext, null).Count(); } This method gets the number of published articles. Instead of using this Table<Article>, what should I use instead?

  • How to launch the market intent in 'Give Feedback' mode on android.

    - by Paul Maidment
    Hi There, I have just written a game for the Android market and would like to remind my customers to leave feeback on the market for the application (especially the demo version.) Is there any way to launch the market intent in a mode that will take the user to the feedback / comments section of the page? I already use this approach for linking my demo to the paid app... Intent goToMarket = null; goToMarket = new Intent(Intent.ACTION_VIEW,Uri.parse("market://details?id=com.paulmaidment.games.flagsoftheworld")); startActivity(goToMarket); Is there a best practice that any Android devs out there might know of? Additionally, is there any way to track referalls from my demo app so that I can try to calculate some kind of a conversion rate? (i.e. how effective the demo app is at generating sales.) Thanks, Paul

  • Edit Html.ActionLink output string

    - by Aaron Salazar
    I'm trying to output the following HTML using Html.ActionLink: <a href="/About" class="read-more">Read More<span class="arrow">?</span></a> I'm getting it done by doing an ActionLink, which outputs an tag and then manipulating the string. <%= Html.ActionLink("[[replace]]", "Index", "About", null, new { @class = "read-more" }).ToHtmlString().Replace("[[replace]]", "Read More" + "<span class='arrow'>?</span>")%></p> It'd be good if I could put HTML directly into the ActionLink but there doesn't seem to be a way based on my internet searches. Sure, it works but it seems like a hack. Is there a better way to accomplish this?

  • Problem with Apache Commons Id UUID Version 1 generation

    - by Pekka Mattila
    My problem is to generate version 1 UUIDs. We use Jetty 6.x, Maven (to start Jetty among other things) and Apache Commons ID (to generate UUID version 1 from the current time). Apache Commons ID requires a configuration file that is told to the JVM, using a parameter, e.g. 'org.apache.commons.id.uuid.config.resource.filename=commons-id-uuid.xml'. I checked the Apache Commons ID code and it tries to find the file from the classpath. Jetty's documentation states that WEB-INF/lib and WEB-INF/classes are in the classpath. The 'commons-id-uuid.xml' can be found from the deployed war file from the root of WEB-INF/classes directory but Jetty cannot load it: Message: java.lang.RuntimeException: java.lang.IllegalStateException: commons-id-uuid.xml loaded as system resource is null Jetty was started using the following command: mvn jetty:run -Dorg.apache.commons.id.uuid.config.resource.filename=commons-id-uuid.xml Any idea what is going wrong? We just need to generate UUID version 1 identifiers. Any suggestions?

  • How to get the row and column of button clicked, in the grid event handler?

    - by younevertell
    Once the added button in grid is clicked, how to find which row and column the button is located in the grid event handler, like click event or some other events? Not the button click event handler #region Grid event handler setup myGrid.MouseEnter += new MouseEventHandler(myGrid_MouseEnter); myGrid.MouseLeave += new MouseEventHandler(myGrid_MouseLeave); myGrid.MouseDown += new MouseButtonEventHandler(myGrid_MouseDown); myGrid.MouseUp += new MouseButtonEventHandler(myGrid_MouseUp); #endregion Thanks I notice that Boyan has some solution for the button click event handler case http://stackoverflow.com/questions/363100/in-wpf-how-can-i-determine-what-column-row-in-a-grid-a-control-is In the Click event handler for the button you say: int row; Button btn = sender as Button; if (btn != null) { row = Grid.GetRow(btn); // And you have the row number... } else { // A nasty error occurred... }

  • How does Linq-to-Xml convert objects to strings?

    - by Eamon Nerbonne
    Linq-to-Xml contains lots of methods that allow you to add arbitrary objects to an xml tree. These objects are converted to strings by some means, but I can't seem to find the specification of how this occurs. The conversion I'm referring to is mentioned (but not specified) in MSDN. I happen to need this for javascript interop, but that doesn't much matter to the question. Linq to Xml isn't just calling .ToString(). Firstly, it'll accept null elements, and secondly, it's doing things no .ToString() implementation does: For example: new XElement("elem",true).ToString() == "<elem>true</elem>" //but... true.ToString() == "True" //IIRC, this is culture invariant, but in any case... true.ToString(CultureInfo.InvariantCulture) == "True" Other basic data types are similarly specially treated. So, does anybody know what it's doing and where that's described?
