  • C# Drag and Drop Effect with Overlay/Opaque Image

    - by CallMeLaNN
    Hi, I think this would be simple question and should be asked in the pas few years but unable to google around and dont know if there is a specific keyword. In c# WinForm I want to do drag and drop but I dont want the image of DragDropEffects Move, Copy or whatever. I want to display an image with half opaque. Just like Firefox when dragging an image, you would see the image folowing the mouse pointer like a ghost :) I already Implement DoDragDrop, DragEnter and DragDrop events. I just want to customize the dragging effects with overlay image.

  • In your opinion what web technology would be best suited for building dropdown menus?

    - by LondonGuy
    What I need is a slide menu that is activated by one click. The menu then appears and doesn't disappear until user clicks any where else on the current page. I don't require any effects but need something reliable that I can style with ease, put a thumbnail of a photo inside change dimensions, add mouse over effects etc. I've done a several searches on google and quite a lot of options are coming up and I'm not too sure which would be best for me. I've seen some people suggestion html + css3 and others suggest jquery. Does any of these options have a benefit over the other? I would appreciate your opinions and maybe some links thanks.

  • 'Advanced' Console Application

    - by keynesiancross
    Hi all, I'm not sure if this question has been answered elsewhere and I can't seem to find anything through google that isn't a "Hello World" example... I'm coding in C# .NET 4.0. I'm trying to develop a console application that will open, display text, and then wait for the user to input commands, where the commands will run particular business logic. For example: If the user opens the application and types "help", I want to display a number of statements etc etc. I'm not sure how to code the 'event handler' for user input though. Hopefully this makes sense. Any help would be much appreciated! Cheers.

  • TTPhotoViewController: How to show small images

    - by Sali
    Hi, I posted this question on Three20 google group but did not get any response. So I thought I try this forum. I am using TTPhotoViewController to display photos. I am following sample code given in Three20 sample project: TTCatalog/PhotoTest1Controller.m. In my case some of the images are less than (320,480). The problem which I am facing is that when my image is 200*300 then TTPhotoViewController re-sizes it to full screen on load which distorts the image. I was wondering if there is a way to tell TTPhotoViewController to display image in its actual size and not to resize it. The only thing which I have changed is viewDidLoad function in PhotoTest1Controller.m. (void)viewDidLoad { self.photoSource = [[[MockPhotoSource alloc] initWithType:MockPhotoSourceNormal title:@"Photo 1" photos:[NSArray arrayWithObjects:[[[MockPhoto alloc] initWithURL:@"http://test/test.jpg" smallURL:@"http://test/test.jpg" size:CGSizeMake(200, 300) caption:@"This is a caption."] autorelease], nil] photos2:nil] autorelease]; } I will appreciate your help. Thanks

  • [solved] What's wrong with this jQuery example?

    - by Sven Larson
    The following jQuery example should put some text into the div, but it doesn't. I tried Firefox, Google Chrome and Internet Explorer. <html> <head> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" language="javascript"></script> <script language="javascript"> $(window).load(function() { $('adiv').html('<p>hello world</p>'); alert('done'); }); </script> </head> <body> <div id="adiv"> </div> </body> </html> Sorry, this might be stupid, but I'm stuck.

  • Focus stealing is evil.

    - by lunixbochs
    A quick Google search for solutions to Focus Stealing in Windows reveals two main result categories: People suggesting incomplete solutions involving the ForegroundLockTimeout registry entry (or TweakUI, which I believe simply changes the aforementioned registry entry), which isn't very effective. Incessant hordes of Windows users complaining about it. It's particularly annoying in two common scenarios: Something triggers a program to popup a dialog window in the background while a fullscreen app is focused, causing the fullscreen app to minimize. A window steals focus while you are typing, stealing all of your keystrokes. If you happen to press Space, Enter, or trigger a keyboard shortcut (like Y for Yes), it can cause completely undesirable outcomes. What creative solutions can be applied to fix this problem for either or both of these scenarios?

  • When using source control, what files should actually be commited?

    - by SimpleCoder
    I am working on a small project, hosted on Google Code, using SVN for source control. This is my first time using source control, and I'm a bit confused about what I should actually be committing to the repository. My project is very simple: A Class Library project, written in C#. The actual code that I have written is a single file. My question is this: Should I be committing the entire project (including directories like Debug, Release, Properties, etc.) or just my main .cs file? Thanks, After fighting with Subversion for a while (note to self: do not reset repository), it looks like I finally have it working with the directories laid out properly. Thanks again for all your advice.

  • Where are graphically pleasing examples of Lists

    - by slim
    Anyone know of good code examples of how to make lists look different than your everyday average black list or more graphically pleasing than you usually see in android apps. I've looked through google code but haven't found too many. I'm looking for different and eye catching lists. I hope this question isn't too generic. Also i'm open to anything, code, examples, blog posts, etc, you name it. I've really struggled with lists and making them look more snazzy. I'm talking more the code level not the graphics or icons used.

  • What is a common name for inheritance, composition, aggregation, delegation?

    - by Eye of Hell
    Hello. After program is separated into small object, these objects must be connected with each over. Where are different types of connection. Inheritance, composition, aggregation, delegation. These types has many kinds and patterns like loose coupling, tight coupling, inversion of control, delegation via interfaces etc. What is a correct common name for mentioned types of connections? I can suggest that they all are called 'coupling', but i can't find any good classification in google, so maybe i'm trying to use a wrong term? Maybe anyone knows a solid, trusted classification that i can user for terminology?

  • Is it better to use GL_FIXED or GL_FLOAT on Android.

    - by Timmmm
    I would have assumed that GL_FIXED was faster, but the iPhone docs actually say to use GL_FLOAT because GL_FIXED has to be converted to GL_FLOAT. Is it the same on Android? I suppose it varies by phone, but what about recent popular ones (Nexus One, Droid/Milestone, etc.)? Bonus points: This appears to be completely undocumented (e.g. search google for GL_FIXED!) but where is the 'point' in GL_FIXED? I.e. how much is (GL_FIXED)1 worth?

  • Is there any Android XML documentation?

    - by Eddified
    Is there any sort of xml reference? I found this which turned out to be invaluable for me http://groups.google.com/group/android-developers/msg/d334017d72909c79 but I can't figure out how I was supposed to know how to do that, had I not found that post. I know that the api reference has xml attributes listed for many of the classes... but what about xml tags? Where is it documented that I could build a shape using , , tags? I'd really like to know where I can find such documentation.

  • Bash script to (more or less) reliably check if the internet is up

    - by João Portela
    I need a bash script to put in a cron job that every minute checks if the internet is up. This is how I did it: #! /bin/sh host1=google.com host2=wikipedia.org curr_date=`date +"%Y%m%d%H%M"` echo -n "${curr_date};" ((ping -w5 -c3 $host1 || ping -w5 -c3 $host2) > /dev/null 2>&1) && echo "up" || (echo "down" && exit 1) How would you do it? Which hosts would you ping? Thanks in advance.

  • Creation of database in Oracle

    - by macha
    Hello, I am a newbie to Oracle, and I have used MySQL for most of the time. So now for testing scripts, I was just planning to create a database, but from the resources I have found on google, it doesn't look as simple it is maybe in mysql or in sqlserver. I just need to create a database, say "CREATE DATABASE TESTDB";. That is it, but of the resources I have found, it seems I need to create an instance identifier, decide an authentication method, create an initialization file etc. Do I really have to do all this or am I using the wrong resources. I just need to create a database and add a few tables into it, just to check my connection string etc. I need to check if I am able to connect to my web server.

  • MySQL 5 in MySQL 4 compatible mode for one database?

    - by Horace Ho
    In a recent project, I have to maintain some PHP code. I set up a development server and installed MySQL, Apache, PHP, ..etc. The program is terminated with an error: Unknown column _ _ _ in 'on clause' Cannot select .... Google shows that it's a change of syntax around JOINs, parentheses are needed. As you may imagine, fixing all that PHP SQL strings will be the last resort. _< Is is possible to config MySQL 5 to run at MySQL 4 compatible mode? Or even better, for only one database? Thanks! p.s. Since we are going to host the code on a new production server (MySQL 5 on a CentOS box), the chance to install MySQL 4 on the new server might be slim.

  • Is there a standardized (Meta?) Tag for the Date of a Website?

    - by Michael Stum
    One thing that search engines really suck with is the date when a website was created. You know the problem: You search for some CSS or JavaScript problem and Google returns a ton of results from 2002 explaining how to fix the problem in IE 5.5 and Netscape 4.6 while the helpful articles are buried on Page 3. There is only one use for Page 3, and meaningful search results are not it. Anyway, I just wonder if there is a standardized or at least generally accepted tag or meta tag that I can put on my own pages to indicate the date they were created? Not that it helps filtering out the old crap out of search results (especially since the people at #1 with their 2002 articles have zero incentive to change), but I'd just like to do my part :P

  • Best way to track impressions/clicks in a bespoke advertisement system?

    - by Martin Bean
    I've been asked to create a bespoke advertisement system despite suggesting open source alternatives such as OpenX and DoubleClick for Publishers (the former Google Ad Manager). I've got the basics of the system set up, i.e. uploading creatives, creating positions and a mechanism to place creatives within positions; however, the area I'm stuck with is impression and click tracking. At the moment an impression and click is stored with the creative, but this then means impressions/clicks can't be queried. For example, we can't find how many impressions were in position x between date y and date z. How would I go about storing that kind of data? My theory was store the creative ID, position ID and timestamp in a database table, but given the amount of traffic the site has this would produce a very large database very quickly. If any one could give me a pointer or two, that would be great.

  • mysql database design: thread and reply of a reply?

    - by ajsie
    in my forum i have threads and replies. one thread has multiple replies. but then, a reply can be a reply of an reply (like google wave). because of that a reply has to have a column "reply_id" so it can point to the parent reply. but then, the "top-level" replies (the replies directly under the thread) will have no parent reply. so how can i fix this? how should the columns be in the reply table (and thread table). at the moment it looks like this: threads: id title body replies: id thread_id (all replies will belong to a thread) reply_id (here lies the problem. the top-level replies wont have a parent reply) body what could a smart design look like to enable reply a reply?

  • How to securely stream video from amazon S3

    - by JP.
    I have couple of copyright videos available on my S3 buckets. I want to stream them on my website, but at the same time. I don't want the users to rip the video from the video player. I tried to google about it but still i am not confident on this, coz i do not know the intricacies of options available like Server Side encryption None/ AES-256 2) A very interesting option is under Metadata tab - It shows couple of keys & Values. How can i use them to secure my video content? 3) Add more meta data and related options?

  • What's causing “Session state has created a session id, but cannot save it because the response was

    - by mike nelson
    I'm getting this fault intermittently. I found this link which summarises fairly well what I was able to find on the Google: http://www.wacdesigns.com/2009/02/03/session-state-has-created-a-session-id-but-cannot-save-it-because-the-response-was-already-flushed-by-the-application/ Basically it says you can try setting the web config setting DisplayWhenNewSession, or try kicking the session state thing into life by getting the Session.SessionID in the Session_OnStart. But does anyone: a) have an explanation for this or even better, b) have a tried and tested fix I realise that I can't flush the response after doing anything that would affect the http response header. If I did this it would cause an error every time but this is intermittent. The SessionID should surely be created by ASP.NET at the beginning of the page response automatically, before anything in the ASPX page or the Page_Load (which is where all my flushes are called).

  • Binding to object properties in C++

    - by Rich.Carpenter
    I've seen in WPF where you can bind control values to properties of other controls. How is that binding accomplished in C++? For example, if I have a class called Car and a guage control called RPM, how do I tie the value of RPM to the member variable Car.RPM, so that when Car.RPM changes, it is automatically (as in without a specific update call coded by me) reflected by the RPM control? General answers or directions to pertinent resources would be fine also, as I'm just beginning to dabble in C++ and haven't had much Google luck with this particular question.

  • Browser graphics: Java Applet vs Flash vs anything else?

    - by Andrey
    Hello! We sell photoalbums which our customers create theirselves using a client album editor program (for Windows). Now we are going to develop an online program so customers could create their albums in the browser: upload photos and edit them. This is going to be a rich browser application with full graphics support. The problem is what technology to use? Our server application is build in Java and we think about Java Applets so that we could reuse some Java-code. We are also not very familiar with Flash. But some people say that Flash is preferred. Maybe there're some modern technologies now? SVG or some Google technologies (like GWT but with graphics support) or something? What do you think? Thanks in advance!

  • Forking Multiple Apps Under Python Subprocess

    - by noxtion
    Hello all. I have been looking through Google and SO for something that could help me solve this but I have run into a block. I am a bit new to Python but I am looking for a way to run multiple apps that will continuously run in the background. For example, I need 4 apps to start up with a param -appnum set to a different value. I would like to use python to count up and then start up a new app that will continue to run. I assumed I would use subprocess but I feel a bit overwhelmed by the documentation. I also plan to have the app print out sequences of numbers and would like to redirect this to a file. I noticed some of the SO questions talked about this, but I am a little confused on what to do. -Mike

  • Is there a better method for scrolling a page (with jQuery) in Safari for iPhone (scrollTop doesn't

    - by Keeron
    Hi there, I am working on an iPhone version of a website, and I am using jQuery .animate() with the scrollTop attribute to scroll to different sections of the page. Something like so: $('html,body').animate({ scrollTop: distance }, 300); On regular web browsers, the scrolling starts from the current window position to the desired position. On the iPhone, the window jumps back to the top of the document before scrolling to the desired position. This is apparently the intended action, but the pages just don't look good with all that movement. Alternatively, on Google.com for the iPhone, when the autosuggest is activated, there is a nice simple scroll to show the autosuggest options below the search box. That's what I'd like to do...

  • How do i change Object to String in a class which extends AsyncTask?

    - by Filip V.
    I'm learning from Google's Android developing tutorial and i came across a problem. On this link https://developer.android.com/training/basics/network-ops/connecting.html#AsyncTask it says to create a class that extends AsyncTask. So when i write the class it automatically implements the method as follows: private Object doInBackground(Object... args) {..} //it's fine but when i try writing just as it says in the tutorial: private String doInBackground(String... args) {..} //it gives an error and the error says: The method doInBackground(String...) of type MainActivity.DownloadWebpageText must override a superclass method. So how do i change Object to String without getting an error there?
