NSView -(void)keyDown in console program

- by Jonas Byström

I'm not getting the -(void)keyDown callback on my inherited NSOpenGLView (note that mouseMoved does not work either though I do setAcceptsMouseMovedEvents:YES, but that is not an issue yet). It implements - (BOOL)acceptsFirstResponder { return YES; } but still no luck. My knowledgeable friend implied that it might have something to do with that the application is still a console application and not a bundled .app (I'm currently porting it). If so: is there some way to circumvent? Could the cause be something else? When I terminate my console application, I frequently see all my keypresses go to stdout so it does seem reasonable...

Embedded applications, similar to iAd, on Iphone OS

- by Tristan

Apple just announced the iAd platform as part of iPhone OS 4. It essentially is an embedded application with a unified interface where you close the embedded application using a small x in the corner. This is obviously a nice experience for users, that could be used by other advertising platforms or to provide an embedded application such as dictionary service. While details remains sketchy on the iPhone OS 4 public APIs, I am wondering if expert iPhone developers know whether this functionality can be replicated by third-party ad providers, or others interested in something like an embedded dictionary service. Is this possible?

how to run href="#var=something" before onclick function fires in javascript?

- by korben

i'm using the below javascript to change an image on an aspx in asp.net c# <script language="JavaScript" type="text/javascript"> var updateImageWhenHashChanges = function() { theImage = document.getElementById("ctl00_ContentPlaceHolder1_Image1a"); if(window.location.hash == "#size=2") { theImage.src = "<%# Eval("realfilename", "/files/l{0}") %>"; } else if(window.location.hash == "#size=3") { theImage.src = "<%# Eval("realfilename", "/files/{0}") %>"; } else if(window.location.hash == "#size=1") { theImage.src = "<%# Eval("fullthumbname", "/thumbnails/{0}") %>"; } else { } } </script> here's how i call it with a link <a href="#size=3" onclick="updateImageWhenHashChanges();">test</a> the problem is that it only does what i'm expecting on the SECOND click of the link, because it seems onclick fires before the href, so the first time i'm just placing the var and the 2nd time i'm actually getting what i want. does anyone know how i can fix this? i'm trying to get the image to change on each click

Javascript to check if there is flash player installed and redirect to the neededn page.

- by themajiks

Hi. I have this script. This determines if there is a flash player installed in the browser, it redirects the browser to a flash website. if not, then it opens a non-flash website. The Code is here: <SCRIPT LANGUAGE="JavaScript">  </SCRIPT> What i want is to embed this code in the non-flash index page. it should just check if there is no flash then simply go with the current index file that already has been opened, or if there is no flash player, then load the index file from within the flash website. Currently, when index.html (non-flash) is opened, it goes into loop and keeps on checking for the flash player. Can I modify the window.location='index.html'; statement no to load any file here, just go on with the file already opened.??

.NET ClickOnce not installing prerequisite files?

- by proudgeekdad

I have a .NET project that uses Crystal Reports. The application is distributed using ClickOnce. Things work great if the user has Crystal installed on their computer. However, not all of the end users have Crystal Reports installed on their computers. These users are receiving the following error... "Unable to install or run the application. The application requires that assembly CrystalDecisions.ReportAppServer.XmlSerialize Version 10.5.3700.0 be installed in the Global Assembly Cache (GAC) first." Is there a way to force ClickOnce installs to ensure that a prerequisite is installed?

Renderbuffer Width (Open GL ES)

- by Josh Elsasser

I'm currently experiencing an issue with an Open GL ES renderbuffer where the backing and width are are both set to 15. Is there any way to set them to the width of 320 and 480? My project is built up on Apple's EAGLView class and ES1Renderer, but I've moved it from the app delegate to a controller. I also moved the CADisplayLink outside of it (I update my game logic with the timestamp from this) Any help would be greatly appreciated. I add the glview to the window as follows: CGRect applicationFrame = [[UIScreen mainScreen] applicationFrame]; [window addSubview:gameController.glview]; [window makeKeyAndVisible]; I synthesize the controller and the glview within it. The EAGLView and Renderer are otherwise unmodified. Renderer Initialization: // Get the layer CAEAGLLayer *eaglLayer = (CAEAGLLayer *)self.layer; eaglLayer.opaque = TRUE; eaglLayer.drawableProperties = [NSDictionary dictionaryWithObjectsAndKeys: [NSNumber numberWithBool:FALSE], kEAGLDrawablePropertyRetainedBacking, kEAGLColorFormatRGBA8, kEAGLDrawablePropertyColorFormat, nil]; renderer = [[ES1Renderer alloc] init]; Render "resize from layer" Method - (BOOL)resizeFromLayer:(CAEAGLLayer *)layer { // Allocate color buffer backing based on the current layer size glBindRenderbufferOES(GL_RENDERBUFFER_OES, colorRenderbuffer); [context renderbufferStorage:GL_RENDERBUFFER_OES fromDrawable:layer]; glGetRenderbufferParameterivOES(GL_RENDERBUFFER_OES, GL_RENDERBUFFER_WIDTH_OES, &backingWidth); glGetRenderbufferParameterivOES(GL_RENDERBUFFER_OES, GL_RENDERBUFFER_HEIGHT_OES, &backingHeight); NSLog(@"Backing Width:%i and Height: %i", backingWidth, backingHeight); if (glCheckFramebufferStatusOES(GL_FRAMEBUFFER_OES) != GL_FRAMEBUFFER_COMPLETE_OES) { NSLog(@"Failed to make complete framebuffer object %x", glCheckFramebufferStatusOES(GL_FRAMEBUFFER_OES)); return NO; } return YES; }

User management with aspnet membership provider

- by 109221793

Hi guys, Just a general question really. I have taken on the management of an application written in C# MVC that uses the asp.net membership api. With this a user can register, change their password, etc. My application consists of two areas, administrator and user. This adminstrator's area has lots of custom admin functionality relating to the application, however has no functionality utilizing the membership api. I want to be able to use the membership api for user management functions such as resetting a password of a user who has forgotten theirs, lock users out, etc. Are there any resources or articles out there that delve into this aspect of using the membership api? Any help would be appreciated :) thanks

Move Global.asax to iHttpModule when using ASP.NET MVC

- by rockinthesixstring

I have successfully created an iHttpModule to replace my Global.asax file in many Web Forms applications. But in looking at the Global.asax file in my MVC application, the methods are totally different. I'm wondering if it is still possible to create this same thing in an MVC app. I know it's not necessary and the Global.asax works just fine. I suppose I just want to have nothing but the web.config in the root directory of my application. Also, I am putting all of my classes in a separate class library project instead of a folder in my MVC application. Not sure if this makes a difference or not.

CSS Flexible Height with scrollable content

- by th3hamburgler

I'm looking to create a flexible width/height page layout with no window scrollbars! Any content that will not fit on the page should be scrollable independently with the overflow property. I've seen plenty of ways to construct flexible width layouts using just HTML and CSS. The following site does a pretty good job on that front: http://ago.tanfa.co.uk/css/layouts/css-3-column-layout-v1.html I wish to implement scrollable content within the 3 centre columns. The content should be scrollable not the column div. e.g. <div class="column"> <h4>Title</h4> <ul> <li>These</li> <li>Items</li> <li>Should</li> <li>Be</li> <li>Scrollable</li> <li>If</li> <li>They</li> <li>Exceed</li> <li>The</li> <li>Window</li> <li>Height</li> </ul> So far if the list exceeds the window height it pushes the footer off page. I'm not to bothered about it working on old versions of IE, although that would score bonus points!

Missing DLL Problem

- by Liran

Hi everyone. I have a C++ native application that was built under VS2005 (sp1),On machine A. (Debug Mode) Now,I need to run this application on a "clean" computer, Clean means it has no VS installed on. When i copy the runtime folder from machine A to the "clean" machine and try to activate the application it demands to reinstall the application. obviously missing DLLs are causing this problem cause on machine A the app works just fine, Is there any "clean" solution for this kind of problem besides gessing which DLLs are missing ? maybe a smart tool or installer that indicates which DLLs are missing at the runtime ? Thanks, Liran

NTLM Authentication fails ONLY with IE against 2k8 App server behind 2k8 IIS7 Reverse Proxy

- by CptSkippy

I'm developing an ASP.NET application for an intranet site that is using Windows/NTLM/WIA/whatever authentication. The application is hosted on a Windows 2k8 server but is accessed through a Reverse Proxy using IIs7 on another 2k8 machine. Authentication works fine in FireFox, Chrome and Safari but fails in IE8. If I circumvent the Proxy and access the application server directly then it works fine so it has something to do with proxy. There's nothing in the Event Viewer on any of the 3 machines to indicate what might be happening. If you connect using IE8 it prompts for your credentials instead of automatically passing them, yes I've setup an explicit trust over an above the domain trust, but it still errors out with a 401 error returned from the proxy. Any ideas where to start troubleshooting this?

Run arbitrary subprocesses on Windows and still terminate cleanly?

- by Weeble

I have an application A that I would like to be able to invoke arbitrary other processes as specified by a user in a configuration file. Batch script B is one such process a user would like to be invoked by A. B sets up some environment variables, shows some messages and invokes a compiler C to do some work. Does Windows provide a standard way for arbitrary processes to be terminated cleanly? Suppose A is run in a console and receives a CTRL+C. Can it pass this on to B and C? Suppose A runs in a window and the user tries to close the window, can it cancel B and C? TerminateProcess is an option, but not a very good one. If A uses TerminateProcess on B, C keeps running. This could cause nasty problems if C is long-running, since we might start another instance of C to operate on the same files while the first instance of C is still secretly at work. In addition, TerminateProcess doesn't result in a clean exit. GenerateConsoleCtrlEvent sounds nice, and might work when everything's running in a console, but the documentation says that you can only send CTRL+C to your own console, and so wouldn't help if A were running in a window. Is there any equivalent to SIGINT on Windows? I would love to find an article like this one: http://www.cons.org/cracauer/sigint.html for Windows.

How to detect Out Of Memory condition?

- by Jaromir Hamala

I have an application running on Websphere Application Server 6.0 and it crashes nearly every day because of Out-Of-Memory. From verbose GC is certain there are the memory leaks(many of them) Unfortunately the application is provided by external vendor and getting things fixed is slow & painful process. As part of the process I need to gather the logs and heapdumps each time the OOM occurs. Now I'm looking for some way how to automate it. Fundamental problem is how to detect OOM condition. One way would be to create shell script which will periodically search for new heapdumps. This approach seems me a kinda dirty. Another approach might be to leverage the JMX somehow. But I have little or no experience in this area and don't have much idea how to do it. Or is in WAS some kind of trigger/hooks for this? Thank you very much for every advice!

iPhone webapp: my ressources don't get cached

- by Savageman

Hello, First of all, I'd like to say I'm not using any off-line feature from HTML5. I have a web-application which runs on the iPhone. When viewing it from safari, everything works quite well. But when I launch the application from the home screen (to remove the navigation bar), it can be really slow. I checked the logs in Apache and it appears that Safari does a good work to cache the resources (css / js / images), with Apache answering "304 Not Modified" when needed. However, when the web app run as a "real" application (navigation bar hidden), those resources doesn't get cached and Apache the content has to be transferred over and over again (response code 200 Ok + content), resulting in a significantly slower page load. How can I prevent this behavior? Do I need to always run my webapp inside Safari, even when it's launched from the home screen? Thank you!

Can silverlight detect or communicate across browser instances?

- by isolatedIterator

User starts up a silverlight application in their browser by navigating to a given URL. User then opens another browser and starts up the same silverlight application by navigating to the same URL. Can the second instance of the application detect that there is already an instance running on the same computer? Can it detect itself if both applications are running within the same browser instance? I would expect the answer to be 'no' but thought that i would ask it anyway. Otherwise i believe that i will have to setup a webservice and have each instance register itself and send requests to other instances from the same IP. does that sound reasonable?

Error Instantiating an Inner Class in Parent's Constructor...

- by stormin986

In my application's main class (subclass of Application), I have a public inner class that simply contains 3 public string objects. In the parent class I declare an object of that inner class. public class MainApplication extends Application { public class Data { public String x; public String y; public String z; } private Data data; MainApplication() { data = new Data() data.x = "String"; } } After I instantiate the object in the constructor, I get a runtime error when I try to assign any of the inner class object's variables. Any idea what's up here??

Retrieving data from database. Retrieve only when needed or get everything?

- by RHaguiuda

I have a simple application to store Contacts. This application uses a simple relational database to store Contact information, like Name, Address and other data fields. While designing it, I question came to my mind: When designing programs that uses databases, should I retrieve all database records and store them in objects in my program, so I have a very fast performance or I should always gather data only when required? Of course, retrieving all data can only be done if it`s not too many, but do you use this approach when you make sure that the database will be small (< 300 records for example)? I have designed once a similar application that fetches data only when needed, but that was slow (using a Access database). Thanks for all help.

How to call another class's method from my app delegate

- by Jared

I have an application that utilizes UILocalNotifications to pop-up UIAlertViews. When the notification fires, the user chooses to go into the app, and this method is called from my app delegate: - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {...} Where I can handle it and where I also prompt another alertview for more information. So when the app launches, it is displaying view A, and then the alertview pops up and prompts for input. This alertview, however, is originating from my app delegate. I need to be able to reload view A when the user hits Yes/No on the alertview. How can I do that from within my app delegate? Any help is appreciated!!

c++ networking issue- retrnsmittion without ccongestion

- by gln

I wrote an application in c++ which send data over tcp connection to several machines.as part of the protocol I use in my application, the other side sends hearbeat messages from time to time, then I know that the connection is still alive. now, I want this application to work on 100 machines or more at the same time. but, I see that sometimes I don't get these heartbeat messages although they sent: I see in wireshark that the packet arrived, then my OS doesn't ack on this message, so there are some retransmit without any ack from my OS. if I look in the window size property - I saw that there is no issue in this part. what can be the root cause for this behavior? it is something in my code that I should change? this is my select code: int res = select(fdCount, &readFds, NULL, NULL, NULL ); I'm using server 2008 r2. Please help me! thanks

access models and forms within modules

- by sims

Hi Stackers, What is the best way to access my models and forms from a controller of a module? Let's explain with "pictures": /application/module/storage/controllers/IndexController.php needs to call readAction in the class called storage_Model_Files in /application/module/storage/models/Files.php I've made this app's dir structure and these forms and models with zf.sh (Zend_Tool). I've read about all sorts of ways of manually including these files. I want to lazy load them much like everything is done automatically with the default module. I can't seem to find how in the docs. Does that make sense? I have: resources.frontController.moduleDirectory = APPLICATION_PATH "/modules" in my application.ini file. So I can access my controllers fine. Thanks for your help!

Python in AWS Elastic Beasntalk: Private package dependencies

- by Adam Matan

I would like to deploy a Python Flask application on beanstalk. The application depends on external packages (e.g. geopy) and internal packages (e.g. adam_geography). The manual Create a requirements.txt file and place it in the top-level directory of your source bundle. This would probably fetch geopy and its dependencies, but would not fetch adam_geography which is available from a custom repo inside my VPC. How do I specify/upload private, internal Python package dependencies in a Beanstalk application?

How to Map a table with another lookup table using JPA?

- by Sameer Malhotra

Hi, I have two tables: 1) Application(int appid, int statusid, String appname, String appcity with getter and Setter methods) 2) App_Status(int statusid,String statusDescription with setter and getter methods) I want to map Application table with App_Status so that I don't have to query separately App_Status table in order to get the statusDescription. One thing I have to careful is that no matter what (Insert,update or delete) to the Application table the App_Status table should be unaffected means its a read only table which is maintained by the DBA internally and used only for lookup table. I am using JPA annotations so please suggest how to handle this.

Communication via internet in Java

- by Stuart

What I mean is like servers on video games. You can run an application and it will set up a server on your computer with an IP and a port. For example, how would you make an application where one host application sets up a thing where it has an IP and a port, and another computer that has access to the internet as well can type in the IP and port and it would be able to communicate with the host? I mean simple communication, like sending a boolean or String. And would there be any security problems that would be needed to fix?
