• Can we have ExtJs components inside a Flex driven page

  - by shafi

  Hi, I am working on a page which mainly consists of Charts and Grids. Thought that Flex would be the best fit with some cool effects. But however, I now feel that ExtJs grid looks better than Flex data grid. My question is whether there is any possibility / mechanism to embed Ext JS grid into a Flex page. Lets say my main page has a Flex tab panel. In first tab, I would like to see 'Flex Chart' and in second tab I would want to see 'ExtJS grid'. I would also want to know of any Flex Data grid plugin (if exists), which looks/works just like Ext Js grid. Thanks & Regards Shafi

• What is the purpose of Java's unary plus operator?

  - by Syntactic

  Java's unary plus operator appears to have come over from C, via C++. As near as I can tell, it has the following effects: promotes its operand to int, if it's not already an int or wider unboxes its operand, if it's a wrapper object complicates slightly the parsing of evil expressions containing large numbers of consecutive plus signs It seems to me that there are better (or, at least, clearer) ways to do all of these things. In this SO question, concerning the counterpart operator in C#, someone said that "It's there to be overloaded if you feel the need." But in Java, one cannot overload any operator. So does this operator exist in Java just because it existed in C++?

• Websites with horizontal accordion effect

  - by peterdp

  Hi Folks, I was delighted with the responses folks offered to the question about horizontal sliding panels that I thought I would try again. In subsequent discussions with my colleagues, it became clearer that we would also like to consider horizontal accordion effects, so I am looking for some concrete, real world examples. Soo... I would once again be most grateful to the stalwart StackOverflowians who could take a moment to paste links to their favorite website(s) that use a horizontal accordion effect well. Extra kudos if you can promote your own site! Thanks so very much if you can help!

• Strange beep when using cout

  - by Unknown

  Hello everyone, today when I was working on some code of mine I came across a beeping sound when printing a buffer to the screen. Here's the mysterious character that produces the beep: '' I don't know if you can see it, but my computer beeps when I try to print it like this: cout<<(char)7<<endl; Another point of interest is that the 'beep' doesn't originate from my on board beeper, but from my headphone/speaker Is this just my computer or there something wrong with the cout function? EDIT: But then why does printing this character produce the beep sound? does that mean that I could send other such characters through the cout function to produce different effects?

• How do I create a downscaled copy of an FBO in OpenGL?

  - by Jasper Bekkers

  Hi, In order to speed up some post-processing shaders I'm using, I need to perform these operations on a framebuffer that is smaller in size than the actual window (about 1/4th or more). Most of the effects I want to optimize are simple blurring operations that could be replaced (for a large part) by smaller kernel and bilinear filtering. Thus, I need to create a copy of the current FBO into another one. However, I couldn't find anything, that works, on how to do this. I've tried using glBlitframebufferEXT and rendering a fullscreen quad into the other framebuffer, but both paths result in a black texture as output. How do I go about solving this problem?

• Are there any design-patterns specifically useful for game-development?

  - by Baelnorn

  This question's been bugging me for a long time. I've always wondered how game developers were solving certain problems or situations that are quite common in certain genres. For example, how would one implement the quests of a typical role-playing game (e.g. BG or TES)? Or how would you implement weapons with multiple stacking effects in a first-person shooter (e.g. the Shrink-gun or Freezer from DN3D)? How would you implement multiple choice options with a possibly intricate decision tree leading to several different outcomes (e.g. the mission trees in WC)? Are there any examples or other resources for that? Blogs? Books? Sourcecode?

• Vim 80 column layout concerns

  - by cdleary

  I feel like the way I do 80-column indication in Vim is incorrect: set columns=80. At times I also set textwidth but I like to be able to see and anticipate line overflow with the set columns alternative. This has some unfortunate side effects -- I can't set number for fear of splitting between files that have different orders of line numbers; i.e. < 100 line files and = 100 line files will require two different set columns values because of the extra column used for the additional digit display. I also start new (g)Vim sessions instead of splitting windows vertically, which forces me to use the window manager's clipboard -- vsplits force me to do set columns every time I open or close a pane, so starting a new session is less hassle. How do you handle the 80-character indication when you want to set numbers, vertically split, etc.?

• Sex appear of computer graphics: movie like UI systems

  - by anon

  It's well know that 1) the way computers actually work 2) the way computers are protrayed in movies are not the same. In particular (2) looks much much cooler than (1). Where can I learn more about making flashy, superficially useful but deepdown useless fancy graphics UIs like that? It's almost in the realm of "hollywood special effects" -- like fire/smoke/fire, but I don't want natural phenomenon; I want user interfaces. Concrete question: where can I learn about creating flashy, cool looking (though not necessairly useful) user interfaces? [Perferably in OpenGL]

• Google maps spatial reference system

  - by JavaRocky

  What is Google map's spatial reference system using when you enter a lat, long into the maps search bar? I've found hints that it might be WGS84 but after converting to that coordinate system, nothing shows up when i paste the coordinates into the google maps search box. I am converting from GDA MGA 56. Sample: Input MGA56 coords: 336301, 6253363 Expected WGS86 coords: -33.8473340793201, 151.230631835944 I get: 16834916.928327594 -4008321.1020318186 Spatial coord systems: EPSG:28356 for MGA56 EPSG:900913 for WGS86 (google maps) I am using geotools to do the transform: CoordinateReferenceSystem crsMga56 = CRS.parseWKT(mga56); CoordinateReferenceSystem crsGmaps = CRS.parseWKT(gmaps); Coordinate coordinate = new Coordinate(336301, 6253363); Point point = new GeometryFactory().createPoint(coordinate); MathTransform transform = CRS.findMathTransform(crsMga56, crsGmaps); Geometry geometry = JTS.transform(point, transform); I know the transform is not correct, as when i use an online tool it gives me the correct coords. http://www.environment.gov.au/cgi-bin/transform/mga2geo%5Fgda.pl?east=336301&north=6253363&zone=56

• g++ How to get warning on ignoring function return value

  - by ArunSaha

  lint produces some warning like: foo.c XXX Warning 534: Ignoring return value of function bar() From the lint manual 534 Ignoring return value of function 'Symbol' (compare with Location) A function that returns a value is called just for side effects as, for example, in a statement by itself or the left-hand side of a comma operator. Try: (void) function(); to call a function and ignore its return value. See also the fvr, fvo and fdr flags in §5.5 "Flag Options". I want to get this warning, if there exists any, during compilation. Is there any option in gcc/g++ to achieve this? I had turned on -Wall but that apparently did not detect this.

• Do employers like to see (programming/computer science) blogs?

  - by incrediman

  I'm wondering if having a blog (with most posts concentrating on computer science/programming) would be a good idea with regards to getting a job. Would a potential employer like to see something like that? What about someone hiring a freelancer? I'd especially appreciate: Responses from people who hire programmers or computer scientists for full-time jobs. Responses from people who hire freelance programmers. Responses from people who have such such blogs and have felt their (either negative or positive) effects. Thanks! I felt this would probably be best marked as community wiki - please let me know if I was mistaken.

• Restart Delphi Application Programmatically

  - by Smasher

  It should not be possible to run multiple instances of my application. Therefore the project source contains: CreateMutex (nil, False, PChar (ID)); if (GetLastError = ERROR_ALREADY_EXISTS) then Halt; Now I want to restart my application programmatically. The usual way would be: AppName := PChar(Application.ExeName) ; ShellExecute(Handle,'open', AppName, nil, nil, SW_SHOWNORMAL) ; Application.Terminate; But this won't work in my case because of the mutex. Even if I release the mutex before starting the second instace it won't work because shutdown takes some time and two instance cannot run in parallel (because of common resources and other effects). Is there a way to restart an application with such characteristics? (If possible without an additional executable) Thanks in advance.

• Scrape zipcode table for different urls based on county

  I used lxml and ran into a wall as my new computer wont install lxml and the code doesnt work.

• Is it valid to have more than one question mark in a URL?

  - by Bungle

  I came across the following URL today: http://www.sfgate.com/cgi-bin/blogs/inmarin/detail??blogid=122&entry_id=64497 Notice the doubled question mark at the beginning of the query string: ??blogid=122&entry_id=64497 My browser didn't seem to have any trouble with it, and running a quick bookmarklet: javascript:alert(document.location.search); just gave me the query string shown above. Is this a valid URL? The reason I'm being so pedantic (assuming that I am) is because I need to parse URLs like this for query parameters, and supporting doubled question marks would require some changes to my code. Obviously if they're in the wild, I'll need to support them; I'm mainly curious if it's my fault for not adhering to URL standards exactly, or if it's in fact a non-standard URL.

• Direct web URL to PayPal transaction

  - by tags2k

  Having implemented PayPal's Website Payments Standard, I'd like to link to the details view of a transaction from my site's back end - just a simple direct web URL to the PayPal side. I don't know why this is tricky but when I try to get it from being logged in to the PayPal system it seems very obfuscated, in this form: history.paypal.com/uk/cgi-bin/webscr?cmd=_history-details&info=[looks like some kind of GUID]&ptype=4&history_cache=[huge encoded string] I'm guessing it's by design but it's not very helpful if you want a quick way to jump to a transaction's details. I've tried the https://www.paypal.com/vst/id=1234 form (also with co.uk as I am UK-based) recommended on a few sites I saw in my search, but I am told that: The transaction ID in your link is invalid. This happens even when copying the transaction ID directly from PayPal's back-end order listing. Is there a reliable way to directly link to an order / transaction details page in PayPal?

• C++ : Lack of Standardization at the Binary Level

  - by Nawaz

  Why ISO/ANSI didn't standardize C++ at the binary level? There are many portability issues with C++, which is only because of lack of it's standardization at the binary level. Don Box writes, (quoting from his book Essential COM, chapter COM As A Better C++) C++ and Portability Once the decision is made to distribute a C++ class as a DLL, one is faced with one of the fundamental weaknesses of C++, that is, lack of standardization at the binary level. Although the ISO/ANSI C++ Draft Working Paper attempts to codify which programs will compile and what the semantic effects of running them will be, it makes no attempt to standardize the binary runtime model of C++. The first time this problem will become evident is when a client tries to link against the FastString DLL's import library from a C++ developement environment other than the one used to build the FastString DLL. Are there more benefits Or loss of this lack of binary standardization?

• Can 3D OpenGL game written in Python look good and run fast?

  - by praavDa

  I am planning to write an simple 3d(isometric view) game in Java using jMonkeyEngine - nothing to fancy, I just want to learn something about OpenGL and writing efficient algorithms (random map generating ones). When I was planning what to do, I started wondering about switching to Python. I know that Python didn't come into existence to be a tool to write 3d games, but is it possible to write good looking games with this language? I have in mind 3d graphics, nice effects and free CPU time to power to rest of game engine? I had seen good looking java games - and too be honest, I was rather shocked when I saw level of detail achieved in Runescape HD. On the other hand, pygame.org has only 2d games, with some starting 3d projects. Are there any efficient 3d game engines for python? Is pyopengl the only alternative? Good looking games in python aren't popular or possible to achieve? I would be grateful for any information / feedback.

• protecting my web page and folder from external using .htaccess and .htpassword in php

  - by Testadmin

  Hai I want to protect a folder (protect) and the files inside that folder. I have created a .htaccess file and put the following code. AuthName "Myfolder" AuthType Basic AuthUserFile url/protect/.htpasswd Require valid-user Also created a .htpassword file which contain username:password When I run my URL http://localhost/url/protect, I got a pop up asking username and password, I entered username as username and password as password. After that I got an error page "server error 500" "The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there was an error in a CGI script. If you think this is a server error, please contact the webmaster." Why this happened?. Any thing wrong here? Anything needs to see my pages under the folder. Please give me the answer.

• WCF high instance count: anyone knows negative sideffects?

  - by Alex

  Hi there! Did anyone experience or know of negative side effects from having a high service instance count like 60k? Aside from the memory consumption of course. I am planning to increase the threshold for the maximum allowed instance count in our production environments. I am basically sick of severe production incidents just because "something" forgot to close a proxy properly. I plan to go to something like 60k instances which will allow the service to survive using default session timeouts at a call rate average for our clients. Thanks, Alex

• Graceful DOS Command Error-Handling w/PHP popen()

  - by Captain Obvious

  PHP 5.2.13 on Windows 2003 I am using the DOS Start /B command to launch a background application using the PHP popen() function: popen("start /B {$_SERVER['HOMEPATH']}/{$app}.exe > {$_SERVER['HOMEPATH']}/bg_output.log 2>&1 & echo $!", 'r'); The popen() function launches a cmd.exe process that runs the specified command; however, if the command fails (e.g. the {$app}.exe doesn't exist or is locked in the above example), the cmd.exe process never returns, and PHP hangs indefinitely as a result. Calling the failing DOS command directly using the Command Prompt results in an Error prompt that requires clicking the OK button. I assume this error confirmation requirement is what's preventing the cmd.exe process from returning to PHP both from the Command Prompt (using both CGI and CLI) and the web (using Apache 2.0 handler w/Apache 2.2). Is there a way to configure PHP, Apache, and/or Win 2003 to return the DOS error to the originating call rather than waiting for confirmation?

• Django Photologue - use photo with original compression

  - by 123

  hi, I´m uploading photos with Django Photologue. Is it possible to leave the jpgs as the are? Even if I tell photosize to use Highest Quality compression the files end up having half as many kb as the originals. I must admit that the visable loss of quality is small but as i am a photographer i would like the images to apear exactly as i edited them (photoshop). I don´t need any of photosize´s cropping and effects tools. Can it be turned off completely? thanks for your answers.

• Is this a "valid" css image replacement technique?

  - by user278457

  I just came up with this, it seems to work in all modern browsers, I just tested it then on (IE8/compatibility, Chrome, Safari, Moz) HTML <img id="my_image" alt="my text" src="images/small_transparent.gif" /> CSS #my_image{ background-image:url('images/my_image.png'); width:100px; height:100px;} Pro's: image alt text is best-practice for accessibility/seo no extra HTML markup, and the css is pretty minimal too gets around the css on/images off issue where "text-indent" techniques hide text from low bandwidth users The biggest disadvantage that I can think of is the css off/images on situation, because you'll only send a transparent gif. I'd like to know, who uses images without stylesheets? some kind of mobile phone or something? I'm making some sites for clients in regional Australia (hundreds of km from the nearest city), where many users will be suffering from dial-up connections, and often outdated browsers too, so the "images off" issue is an important consideration. are there any other side effects with this technique that I haven't considered?

• Huge AS 3.0 Export Frame

  - by goorj

  I am creating a very simple flash animation with no code or complex effects, just text and simple tweens (Flash CS5) But I have problems reducing the size of my swf. From the generated size report, it looks like it has to do with fonts and/or exported actionscript classes. The frame with AS 3.0 Classes is over 100K, and even though I am only using one fonts, the same characters are embedded/exported multiple times My questions are: Do embedding of mixed TLF/Classic text (or mixing other text properties, spacing/kerning etc) require the same characters to be embedded twice? Do text transformations on TLF text (rotation and different transformations not available in classic text) require embedding of ("internal") AS3 classes that will increase the size of the .swf? (even though none of these classes are explicitly used by me, there are no scripts in the fla project) I have tried removing all the text instances one by one, and at one point, the swf is reduced to only 5-6K, but I am not able to pinpoint exactly what causes the ballooning of the swf
