  • C/C++ enum and char * array

    - by Eric M
    Ran accross the following code in an article and didn't think it was standard C/C++ syntax for the char* array. As a test, both Visual C++ (visual studio 2005) and C++ Builder Rad XE both reject the 2nd line. Without using #defines, anyone have any tricks/tips for keeping enums and a string array sort of in sync without resorting to STL ? More of a curiosity question. enum TCOLOR { RED, GREEN, BLUE }; char *TNCOLOR[] = { [RED]="Red", [GREEN]="Green", [BLUE]="Blue" }; as an aside, the article this came from is quite old and I believe this might work under GCC but have not tested.

  • What is the best way to have a dynamic dropdownlist in PHP and POST selected value

    - by mouthpiec
    Hi, I am writing the following in PHP: i would like to have 2 dropdownlists, where the second one is populated from a mySQL dB according to the choice made on the first dropdown list. Then I would like to use the values of the selected values of the dropdownlist to call another PHP page in which I will generate a db query. Eg: List A: Car Manufactures (honda, nissan, etc) List B: Models (accord, civic, etc) Then I will have a submit button, to POST the values in another PHP file? (I have the basics of how to perform the above without having a dynamic list, but I tried this with AJAX, but I am having problems to pass the value of the second dropdownlist) Any tips of how I can perform the above?

  • MySQL encoding problem

    - by heffaklump
    I use Java and JDBC to save japanese characters and it works perfectly on my local MySQL. But when I tried doing the same thing on my web hotels MySQL i get ????? instead of japanese characters. I have made the exact same tables and use exact same code. The only difference I have found is SHOW VARIABLES LIKE 'CHAR%' character_set_client utf8 character_set_connection utf8 character_set_database latin1 character_set_filesystem binary character_set_results utf8 character_set_server latin1 character_set_system utf8 character_sets_dir /s/usr-local/share/mysql/charsets/ character_set_datbase is set to latin1. But I can't change it! Any tips?

  • What is the easiest way to loop through a folder of files in C#?

    - by badpanda
    I am new to C# and am trying to write a program that navigates the local file system using a config file containing relevant filepaths. My question is this: What are the best practices to use when performing file I/O (this will be from the desktop app to a server and back) and file system navigation in C#? I know how to google, and I have found several solutions, but I would like to know which of the various functions is most robust and flexible. As well, if anyone has any tips regarding exception handling for C# file I/O that would also be very helpful. Thanks!!! badPanda

  • Getting started with learning the Rails source

    - by japancheese
    Hello, I've been using Ruby on Rails for many projects lately, and I thought it would be interesting to take a look at the Rails source and really see how things operate underneath. I think it'd be a great learning experience and would probably enhance the way I code Rails apps all the more. Does anyone have any tips on how to get started? And where within the Rails source does an application begin to be executed? Perhaps if I started there, I could see how everything is loaded and works in general.

  • UINavigationController as child view of UIViewController

    - by Gregg
    I have an application that isn't nav based. So there is no UINavigationController in the App Delegate. However, I need to switch to a UINavigationController for a piece of the application. Steps I currently took... Create a new Class that extends UIViewController Added a UINavigationController via IB Told IB that the new UIViewController's view is the view for the UINavigationController The problem now is that the File's Owner needs it's view set. But via IB there is no way to specify this. So obviously, I'm not going about this the right way. Any tips in the right direction are much appreciated.

  • How To Discover RSS Feeds for a given site.

    - by ktolis
    The quest is, given a site url (say http://stackoverflow.com/ ) to return the list of all the feeds available on the site. Methods acceptable: a) use a 3rd party service (google?, yahoo?, ...) programmatically b) using a crawler/spider (and some tips on how to configure the spider to return the rss/xml feeds only) c) programmatically using c/c++/php (any language/library) The task here is not to get the feeds contained on the page returned by the url but ALL the feeds that are available on the server at any depth... in any cases please provide a simple usage example.

  • How to implement an ItemsControl3D which can use templates of Visual3D?

    - by Christo
    I'm looking for something like a ContainerUIElement3D which supports the ItemsSource property and an ItemTemplate property which I can use within a Viewport3D. My aim is to be able to write something like: <ItemsControl3D ItemsSource="{Binding Path=MyItems}"> <ItemsControl3D.ItemTemplate> <DataTemplate3D> <!-- My template which defines the binding to each item. --> <DataTemplate3D> </ItemsControl3D.ItemTemplate> </ItemsControl3D> I'm looking for tips on how to implement this. The first tricky part is to create a DataTemplate3D which can construct the Visual3D needed to add to the ItemsControl3D. I've been using .NET reflector to browse through the implementation of ItemsControl and DataTemplate, but I soon realised that I don't have a deep enough understanding and enough time to come up with a solution on my own.

  • Migrating a simple application from Application Delegate to ViewController Class

    - by eco_bach
    Hi Frst of all wanted to send out a huge thanks for the great feedback and support. I have a simple application working, right now simply loads a sequence of images and alows the user to step thru the images by clicking a button. All of my logic is in my Application Delegate class, with the image loading, initialization of UIImage Views etc happening in my applicationDidFinishLaunching method. My next step is to migrate as much as possible all of the logic from this class to a ViewController, to take advantage of the extra functionality etc in viewcontrollers. All my images and imageViews are initialized like the following in my applicationDidFinishLaunching. img = [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@image1.jpg" ofType:nil]]; imgView = [[UIImageView alloc] initWithImage:img]; How would I migrate this to a ViewController based application? Where would I put all of the logic currently in my applicationDidFinishLaunching method, or for loading of images, is it necessary to only load them here? Any feedback, tips, suggestions appreciated.

  • JAVA: 500 Worker Threads, what kind of thread pool?

    - by Submerged
    I am wondering if this is the best way to do this. I have about 500 threads that run indefinitely, but Thread.sleep for a minute when done one cycle of processing. ExecutorService es = Executors.newFixedThreadPool(list.size()+1); for (int i = 0; i < list.size(); i++) { es.execute(coreAppVector.elementAt(i)); //coreAppVector is a vector of extends thread objects } I do need a separate threads for each running task, so changing the architecture isn't an option. I tried making my threadPool size equal to Runtime.getRuntime().availableProcessors() which attempted to run all 500 threads, but only let 8 (4xhyperthreading) of them execute. The other threads wouldn't surrender and let other threads have their turn. I tried putting in a wait() and notify(), but still no luck. If anyone has a simple example or some tips, I would be grateful!

    - by mkoso
    I would like to make a html/js widget that people can add to their blogs, sites etc. I have never made widgets before so I would like to hear what should be done and what not. For example, how do I make the styling? Inline, own css file or what is the best practise? I believe i cant use head and body stuff in it. What about h1, h2 etc? Do they screw the website that has the widget or can i use them? If you have any good tips I would like to hear those. Thanks.

  • Optimizing tiled maps in cocos2d-iphone

    - by Omega
    My cocos2d-iphone game has tiled maps. The tilesets textures are rather big. I got around 5 tilesets and each one is 2048x2048 (retina). My maps are around 80x80. They have around 8 layers and each one is obviously using one tileset. The frame rate falls (it goes around 30 sometimes. I know 30 is rather aceptable, but still, I want 50+). So given that textures are huge I can't afford to make many layers (since each one loads a texture of these). So how about I divide my tileset textures into much smaller tilesets (like 1024x1024 each)? That will allow me to use many more layers for my maps, right? Are there any other tips for huge retina display tile maps?

  • SQL help - find the table that has 'somefieldId' as the primary key?

    - by Kettenbach
    Hello All, How can I search my sql database for a table that contains a field 'tiEntityId'. This field is referenced in a stored procedure, but I am unable to identify which table this id is a primary key for? Any suggestions? I currently look through stored procedure definitions for references to text by using something like this Declare @Search varchar(255) SET @Search='[10.10.100.50]' SELECT DISTINCT o.name AS Object_Name,o.type_desc FROM sys.sql_modules m INNER JOIN sys.objects o ON m.object_id=o.object_id WHERE m.definition Like '%'+@Search+'%' ORDER BY 2,1 Any SQL guru's out there know what I need to use to find the table that contains the field, 'preferably the table where that field is the Primary Key. Thanks so much for any tips. Cheers, ~ck in San Diego

  • I just don't know what it is, tried everything, IE 7 bug

    - by Emmy
    Has anyone seen this bug? I have a sidebar with a ul nav background image for the hover state, floated right, looks great in all browsers. Then...I added another div underneath it for ad space. inside, there's an anchored image. That image tucks underneath the background image of the nav, but only in IE7 (i abandoned trying to please ie6). So I took it out of the sidebar, played with float, display,height hacks, but nothing works I can declare a large top margin with some more top padding do get it to clear but it breaks the design. i even tried creating a div called clear and put a top margin there. so it displays with this huge gap in chrome, FF, safari but this tiny space between in IE. i even tried creating a div called clear and put a top margin there. I have spent hours trying to find someone with the same problem but to no avail. Any suggestions? Here's a code snippet: <div id="leftsidebar"> <div id="leftnav"> <ul class="slidenav" id="sidenav"> <li id="overview" class="inactive"> <a href="expat.html">expat lifestyle</a> </li> <li id="tips" class="inactive"> <a href="traveltips.html">travel tips</a> </li> <li id="bts" class="inactive"> <a href="bts-mrt.html">bts/mrt</a> </li> <li id="bus" class="inactive"> <a href="bus.html">bus system</a> </li> <li id="van" class="inactive"> <a href="taxi.html">vans/taxis</a> </li> <li id="boat" class="inactive"> <a href="klong.html">boats/klong</a> </li> <li id="boat" class="inactive"> <a href="klong.html">boats/klong</a> </li> <li id="tuk" class="inactive"> <a href="tuk.html">tuk-tuks</a> </li> <li id="train" class="inactive"> <a href="train.html">trains</a> </li> <li id="airport" class="inactive"> <a href="airport.html">int'l airport</a> </li> <li id="dangers" class="inactive"> <a href="dangers.html">dangers</a> </li> <li id="fun" class="inactive"> <a href="fun.html">fun places</a> </li> <li id="shopping" class="inactive"> <a href="shopping.html">shopping</a> </li> </ul> </div> </div> <div id="store"> <a href="astore.amazon.com/ten044-20"; title="Shop WIB store"> <img src="images/WIBstore.png" height="70" width="200" border="none"/> </a> </div> the corresponding CSS: #leftsidebar { float:right; width: 210px; margin: 40px 0 0 0; padding: 0; height:1%; } #store { margin: 20px 0px 0 0px; padding: 0 10px 0 0; float: right; height: 1%; display: inline; } And an image:

  • SSIS Custom Control Task Debugging UI in BIDS and VS

    - by zeencat
    I've created a SSIS Custom Task in C# and I'm currently developing the UI. I was wondering if there is a better way of debugging the UI instead of compiling the project, copying the DLL's into the appropriate DTS folder and then opening the test Package within BIDS and then attaching the process to Visual Studio. This part I'm not bothered about but once you've tested the UI and made changes to UI within Visual Studio. I've got to recomplile the DLL's and then repeat the entire process. I've got to close BIDS and VS because they don't release the DLL's before I have to start the entire process over again. Does anyone have any tips to speed up this process. It's just so frustrating having to do this everytime.

  • How to generate a report of IIS settings for easy perusal?

    - by Bryan
    Hello, I'm looking for a way to (hopefully) create a text file which lists all the settings in IIS for.. Virtual Directories Web sites Which framework is used on a certain website/directory directory of hosted files etc. Basically I want to do some investigation on some of our servers to figure out where certain projects are located, without digging through right clicking and looking for the directory name manually, etc, for every domain we host. The reasoning is that I often need to find access to files/projects I haven't worked on before, but historically, we don't have a strong naming scheme, so you can't just look where something "logically" would be - so, generating a list would be very helpful. Something like this would be awesome, but I'm looking for any tips at all Domainname1.com framework: ASP.NET 1.1 directory: c:\inetpub\wwwroot\domainname1.com Applications hosted at this domain: etc, etc. Plain text, XLS, XML.. anything other than right clicking through the whole list! Thanks!

  • Is there a more efficient way to retrieve tables from websites using wpf + webclient

    - by Jordan Brooker
    new to the community, but here is my first question that I am stuck on. I am new to WPF and WebClient using c# and I am attempting to make a program that access www.nba.com to populate a combobox I have with team names, and then when a user selects a team from the combobox, I wanted to populate a portion of the main window with the roster from the teams home site, same style and eveything. I was able to populate the combobox using the WebClient.OpenRead and reading in the markup to extract the team names. Now I am on the more difficult part. I was planning on using the same method to grab all the markup and then somehow display the table in a content panel, but I feel that this is a very tedious thing to do. Can anyone give me any tips for completing this action or is there a method in the webclient class that allows me to search a webpage for a table or object other than text? Thanks.

  • I have the CSS & JS, how do I convert that to erb for my Rails app?

    - by marcamillion
    So I have the foundation of my Rails app, then I went ahead and did the JS and CSS. How do I then take the CSS and JS that I have, and apply it to the app in a 'Rails Way'. i.e. a dynamic way that works nicely. Can you give me some tutorials/articles/resources that I can read up to guide me, please? I have tried the Rails guides, but I find them a bit lacking. Any other good suggestions or tips that might help get me on the right track? Thanks.

  • Programming language for fast calculations with big integers

    - by sub
    I'm doing Project Euler problems at the moment and I can solve most of them using my own programming language which uses direct C++ integers (so they are bound to 2^32 on my machine). However, at times there are problems which require me to work with very high numbers, I can't do that with native integers. So I implemented a BigInt library in my language which unfortunately gets extremely slow at times. Is there a programming language suitable for very efficient handling of big numbers? I mean that I want to do the things I could do in other programming languages with it (variables, loops, etc.), but in a faster way. If you have got tips for workarounds of the 2^32 limit in my language/C++/other languages, please tell me too!

  • How to drag and scroll in a div with jQuery

    - by Don Munter
    Hey guys, I've been looking around for some time now, but I can't find a way to combine these elements: I want a 100% width div, with 1 row of elements. I need to scroll through this div, just like: http://jqueryfordesigners.com/demo/scrollable-timelines.html So with a hidden overflow and such. But now I want some sort of smooth ease when I let go of the mouseclick, so it'll be like a sort sweep. So when I drag the screen from left to right, and let go of the mouse, it'll move on for 1 sec and linearly slowing down. Hm, am I making sense? Does anyone know of any scripts or some tips to put me back on track? Don
