• iPhone/ObjC - How to create a custom keyboard

  - by HM1

  Hi, iPhone/objC question: How do I go about creating a custom keyboard/keypad that will show up when some one taps on a UITextField? I would like to display a keypad with a, b, c, 1, 2, 3 and an enter button, nothing else. The keypad should work and behave like the standard keyboard does (in behavior) but it will definitely look different. I can't find any example and the best I've found is to filter characters with existing keyboard which is an unacceptable solution. Thanks in advance, Hiren.

• iPad doesn't trigger resize event going from vertical to horizontal?

  - by dclowd9901

  Has anyone noticed this behavior? I'm trying to write a script that will trigger upon a resize. It works fine on normal browsers, works fine on iPhone, but on iPad, will only trigger going from horizontal to vertical viewport, not vice versa. Here's the code: $(window).resize( function() { var agent=navigator.userAgent.toLowerCase(); var is_iphone = ((agent.indexOf('iphone') != -1)); var is_ipad = ((agent.indexOf('ipad') != -1)); if(is_iphone || is_ipad){ location.reload(true); } else { /* Do stuff. */ }; });

• IIS7 Overrides customErrors when setting Response.StatusCode?

  - by Nicholas H

  Having a weird problem here. Everybody knows that if you use web.config's customErrors section to make a custom error page, that you should set your Response.StatusCode to whatever is appropriate. For example, if I make a custom 404 page and name it 404.aspx, I could put <% Response.StatusCode = 404 % in the contents in order to make it have a true 404 status header. Follow me so far? Good. Now try to do this on IIS7. I cannot get it to work, period. If Response.StatusCode is set in the custom error page, IIS7 seems to override the custom error page completely, and shows it's own status page (if you have one configured.) Has anyone else seen this behavior and also maybe know how to work around it? It was working under IIS6, so I don't know why things changed. Update: This is not the same as the issue in http://stackoverflow.com/questions/347281/asp-net-custom-404-returning-200-ok-instead-of-404-not-found

• XML multiline comments in C# - what am I doing wrong?

  - by Dave

  According to this article, it's possible to get multiline XML comments -- instead of using ///, use /** */. This is my interpretation of what multiline comments are, and what I want to have happen: /** * <summary> * this comment is on line 1 in the tooltip * this comment is on line 2 in the tooltip * </summary> */ However, when I use this form, the tooltip that pops up when I hover over my class name in my code is single-line, i.e. it looks exactly as if I had written my comment like this: /// <summary> /// this comment is on line 1 in the tooltip /// this comment is on line 2 in the tooltip /// </summary> Is this behavior actually possible still in VS2008?

• Are google chrome extension "content" scripts sandboxed?

  - by jabapyth

  I was under the impression that the content_scripts were executed right on the page, but it now seems as though there's some sandboxing going on. I'm working on an extension to log all XHR traffic of a site (for debugging and other development purposes), and in the console, the following sniff code works: var o = window.XMLHttpRequest.prototype.open; window.XMLHttpRequest.prototype.open = function(){ console.log(arguments, 'open'); return o.apply(this, arguments); }; console.log('myopen'); console.log(window, window.XMLHttpRequest, window.XMLHttpRequest.prototype, o, window.XMLHttpRequest.prototype.open); This logs a message everytime an XHR is sent. When I put this in an extension, however, the real prototype doesn't get modified. Apparently the window.XMLHttpRequest.prototype that my script is seeing differs from that of the actual page. Is there some way around this? Also, is this sandboxing behavior documented anywhere? I looked around, but couldn't find anything.

• htaccess Redirect - First Segment to PHP File, Second Segment as Parameter

  - by Steve

  My htaccess redirect knowledge is somewhat weak, so I was hoping to get some help here. I currently have the following redirect, which works well: # remove trailing slash RewriteRule ^(.*)/$ /$1 [L,R=301] # redirect to clean URL RewriteCond /%{REQUEST_FILENAME}.php -f RewriteRule ^([a-zA-Z0-9_-\s]+)$ /$1.php This takes a URL like www.mysite.com/about to www.mysite.com/about.php Now I would like to keep this behavior, but add parameters (if applicable), as such: www.mysite.com/about = www.mysite.com/about.php www.mysite.com/gallery/1 = www.mysite.com/gallery.php?id=1 If possible, I might like to expand this system to 2 or more parameters, as such: www.mysite.com/gallery/1/2 = www.mysite.com/gallery.php?id=1&section=2 So the pattern would be: First URL segment redirects to a PHP file (Optionally) the second segment gets added as the id parameter (Optionally) the third segment gets added as the section parameter

• Entity Framework 4: C# !(ReferenceEquals()) vs !=

  - by Eric J.

  Unless a class specifically overrides the behavior defined for Object, ReferenceEquals and == do the same thing... compare references. In property setters, I have commonly used the pattern private MyType myProperty; public MyType MyProperty { set { if (myProperty != value) { myProperty = value; // Do stuff like NotifyPropertyChanged } } } However, in code generated by Entity Framework, the if statement is replaced by if (!ReferenceEquals(myProperty, value)) Using ReferenceEquals is more explicit (as I guess not all C# programmers know that == does the same thing if not overridden). Is there any difference that's escaping me between the two if-variants? Are they perhaps accounting for the possibility that POCO designers may have overridden ==? In short, if I have not overridden ==, am I save using != instead of ReferencEquals()?

• Creating a ListView using Category (Control Panel-Like) View

  - by Andrew Moore

  I currently have an application which uses a regular ListView with groups to show a bunch of modules. I would like to use a Category view. Category view is the new view introduced in Windows Vista for the Control Panel: Is there a third party control or a way (via API) to create a ListView which mimics the behavior of the Windows 7 Control Panel? Categories with icons and action links. Separate events for Category Click and Action Click. One or two column layout Separators between action links or lines

• Cross-Browser jQuery text-zoom implementation

  - by JMC Creative

  I've got some code to increase/decrease font size. This is giving me a headache because each browser seems to implement the $.css('font-size') differently (see jquery bug). The part that's really killing me, though, is that Firefox is scaling up okay, but when I use the scale down function below, it scales up. Webkit & IE are both working as expected. Any ideas on that? I put this in a fiddle here: http://jsfiddle.net/srQ3P/1/ where you can see it working as expected, and you can see it broken in firefox at the project page: http://cumberlandme.info/residents MAJOR EDIT Sorry, the issue is not the code, it's firefox buggy behavior. After I zoom in or out with the browser controls (ctrl + plus or ctrol + minus) the js goes haywire. This doesn't happen in other browsers. This is the real issue. Any advice on that

• Applet problem with IPlanet and Firefox (class not found)

  - by JB Hurteaux

  I have an applet which loads nicely when accessed locally (both IE and Firefox). However, when I put my webpage in a webserver (local IPlanet), it refuses to load on Firefox (but still fine on IE). I get the following error in the java console: load: class XXX.localprinting.LocalPrintingApplet.class not found. java.lang.ClassNotFoundException: XXX.localprinting.LocalPrintingApplet.class at sun.plugin2.applet.Applet2ClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.plugin2.applet.Plugin2ClassLoader.loadCode(Unknown Source) at sun.plugin2.applet.Plugin2Manager.createApplet(Unknown Source) at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Unknown Source) at java.lang.Thread.run(Unknown Source) Caused by: java.io.IOException: open HTTP connection failed:https://XXX/test/XXX/localprinting/LocalPrintingApplet/class.class at sun.plugin2.applet.Applet2ClassLoader.getBytes(Unknown Source) at sun.plugin2.applet.Applet2ClassLoader.access$000(Unknown Source) at sun.plugin2.applet.Applet2ClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) ... 7 more Exception: java.lang.ClassNotFoundException: XXX.localprinting.LocalPrintingApplet.class Any idea what could explain the different behavior in the webserver? I researched the issue of "class not found" already but without finding something relevant.

• How to create a string array in matlab?

  - by aduric

  I would like to pass a vector of strings from C++ to matlab. I have tried using the functions available such as mxCreateCharMatrixFromStrings but it doesn't give me the correct behavior. So, I have something like this: void mexFunction( int nlhs, mxArray *plhs[], int nrhs, const mxArray *prhs[]) { vector<string> stringVector; stringVector.push_back("string 1"); stringVector.push_back("string 2"); //etc... The problem is how do I get this vector to the matlab environment? plhs[0] = ??? My goal is to be able to run: >> [strings] = MyFunc(...) >> strings(1) = 'string 1'

• Custom DataGridView column sort based on Value not Formatted value

  - by Dan Neely

  I have a custom DGV cell I'm using to display the contents of MyType objects. To control how they're being formatted I'm overriding the GetFormattedValue() and FormattedvalueType methods of DataGridViewTextBoxCell because in this case I don't want to use the default ToString() method. The problem is that when I do this the DGV is sorting the column by the string in FormattedValue instead of by Value. I'm not seeing a method I can override to change the sort behavior of the column. While I know I can, I don't want to have to write custom Sort mthods for the DGVs themselves because I'm using this in multiple DGV's.

• File Explorer using Java - how to go about it?

  - by user299988

  Hi, I am set to create a file explorer using Java. The aim is to emulate the behavior of the default explorer as closely as possible, whatever may be the underlying OS. I have done NO GUI programming in Java. I have looked-up Swing, SWT and JFace, and I am beginning my project with this tutorial: http://www.ibm.com/developerworks/opensource/library/os-ecgui1/ I would like to know your opinions about the best approach to tackle this problem. If you could comment on complexity of coding, portability and OS-independence, and efficiency, it would be great. Is there anything else I should know? Do some other ways exist? Thanks a lot!

• IWebBrowser2: how to force links to open in new window?

  - by Rob McAfee

  The MSDN documentation on WebBrowser Customization explains how to prevent new windows from being opened and how to cancel navigation. In my case, my application is hosting an IWebBrowser2 but I don't want the user to navigate to new pages within my app. Instead, I'd like to open all links in a new IE window. The desired behavior is: user clicks a link, and a new window opens with that URL. A similar question was asked and answered here and rather than pollute that answered post, it was suggested I open a new discussion. The members on the related post suggested I should be able to do this by trapping DISPID_BEFORENAVIGATE2, setting the cancel flag, and writing code to open a new window, but I've found out that the browser control gets lots of BeforeNavigate2 events that seem to be initiated by scripts on the main page. For example, amazon.com fires BeforeNavigate2 events like crazy, and they are not a result of link invocation. Replies appreciated!

• Using MonadPlus in FRP.Reactive.FieldTrip

  - by ony

  I'm studying FRP at this moment through FieldTrip adaptor. And hit the problem with strange way of frames scheduling and integration. So now I'm trying to build own marker Event for aligning Behaviour stepping. So... flipflop :: Behavior String flipflop = stepper "none" (xflip 2) where xflip t0 = do t <- withTimeE_ (atTime t0) return "flip" `mplus` xflop (t+3) xflop t0 = do t <- withTimeE_ (atTime t0) return "flop" `mplus` xflip (t+2) txtGeom = ((uscale2 (0.5::Float) *%) . utext . show <$>) main = anim2 (txtGeom . pure flipflop) Questions is: Why this example leads to memory leak? Is there safe way to build sequence of events where each next one is scheduled depending on previous?

• Discrete event simulation framework for .NET

  - by Kuba

  Does anyone have an experience with some discrete event simulation library that could be used in .NET (C#)? Despite the basic functionality for queing events and dispatching them, it would be fine to have some non-deterministic behavior (e.g. failures simulation). I have some tips and I am even considering to write my own, but first, I would like to collect some recomendations. Thanks. Additional info: i'm not looking explicitly for free product, however, the prize matters :) Just to precise the field i need to map, here is the example of a product: http://www.holushko.com/index.html

• Multiple Post Requests Occuring in Quick Succession

  - by Samuel

  This is a bit of an open ended question but we have a problem with a web application that on the final step of completing an order, multiple post requests are being made, sometimes up to 10 and all within a couple of seconds to the page. Theirs nothing unusual about the page, the user fills out a form which is then validated using the jQuery form validation plugin. We've seen this behavior exhibited over a couple of different browser types, notably IE6 but also IE8. We've also managed to trigger the bug ourselves but nothing out of the ordinary seems to occur on the browsers end, everything progresses as normal. Apache logs show that multiple post requests where made at the same time and the Rails logs show that multiple posts requests were also received by the application, leading me to think it's a problem with the browser. I've exhausted all avenues that I can think of for debugging so I'm throwing this out there to see if anyone has some ideas of what we could try or look for next.

• WCF Service error received when using TCP: "The message could not be dispatched..."

  - by StM

  I am new to creating WCF services. I have created a WCF web service in VS2008 that is running on IIS 7. When I use http the service works perfectly. When I configure the service for TCP and run I get the following error message. There was a communication problem. The message could not be dispatched because the service at the endpoint address 'net:tcp://elec:9090/CoordinateIdTool_Tcp/IdToolService.svc is unavailable for the protocol of the address. I have searched a lot of forums, including this one, for a resolution but nothing has worked. Everything appears to be set up correctly on IIS 7. WAS has been set up to run. The default web site has a net.tcp binding and the application has net.tcp under the enabled protocols. I am including what I think is the important part of the web.config from the host project and also the app.config from the client project I am using to test the service. Hopefully someone can spot my error. Thanks in advance for any help or recommendations that anyone can provide.

• Subdomain mapping to another external subdomain

  - by Davorin

  I'm trying to map help.domain1.com to help.domain2.com. I've seen this on UserVoice. They let you map something.yourdomain.com to something.uservoice.com. On domain1.com I've set up a CNAME to help.domain2.com. It works fine but when I open help.domain1.com I get the content of domain2.com instead of help.domain2.com. After some experimenting I've realized that this is an expected behavior. So my question is what do I have to do on domain2.com (or maybe on domain1.com?) to have it show content of subdomain "help.domain2.com" when I navigate help.domain1.com? (I'm using Plesk and the OS is Windows Server 2003)

• Scroll Gestures not Passed to IScrollInfo implementing panel in Windows Phone 7 CTP

  - by user50088

  I am using a custom panel as a ItemsPanel for a ItemsControl in a with a custom template that provides for a scroll viewer. (See Xaml below.) So long as my panel does not implement IScrollInfo, scrolling works in this scenerio. I implement IScrollInfo and update my viewport and extent sizes in measure override. The scroll bar shows the correct relative size, and if I call the IScrollInfo methods directly, scrolling works as expected. However, the drag and flick gestures no longer scroll the content. Putting a breakpoint on the input of every IScrollInfo method shows that drag and pick are not calling the interface. Removing the IScrollInfo interface declaration restores the scroll on drag and flick behavior. Is there a simple way to restore the flick and pan gestures to ItemControls with panels that implement IScrollInfo?

• Is this class + constructor definition pattern overly redundant?

  - by Protector one

  I often come across a pattern similar to this: class Person { public string firstName, lastName; public Person(string firstName, string lastName) { this.firstName = firstName; this.lastName = lastName; } } This feels overly redundant (I imagine typing "firstName" once, instead of thrice could be enough…), but I can't think of a proper alternative. Any ideas? Maybe I just don't know about a certain design pattern I should be using here? Edit - I think I need to elaborate a little. I'm not asking how to make the example code "better", but rather, "shorter". In its current state, all member names appear 3 times (declaration, initialization, constructor arguments), and it feels rather redundant. So I'm wondering if there is a pattern (or semantic sugar) to get (roughly) the same behavior, but with less bloat. I apologize for being unclear initially.

• How to initialize an std::string using ""?

  - by Mohsin

  I'm facing problems with initializing a std::string variable using "" (i.e. an empty string). It's causing strange behavior in code that was previously working. Is the following statement wrong? std::string operationalReason = ""; When I use the following code everything works fine: std::string operationalReason; operationalReason.clear(); I believe that string literals are stored in a separate memory location that is compiler-dependent. Could the problem I'm seeing actually be indicating a corruption of that storage? If so, it would get hidden by my usage of the clear() function. Thanks.

• Does a C++ destructor always or only sometimes call data member destructors?

  - by Magnus

  I'm trying to validate my understanding of C++ destructors. I've read many times that C++ supplies a default destructor if I don't write one myself. But does this mean that if I DO write a destructor that the compiler WON'T still provide the default cleanup of stack-allocated class fields? My hunch is that the only sane behavior would be that all class fields are destroyed no matter what, whether I provide my own destructor or not. In which case the statement I've read so many times is actually a little misleading and could be better stated as: "Whether or not you write your own destructor, the C++ compiler always writes a default destructor-like sequence to deallocate the member variables of your class. You may then specify additional deallocations or other tasks as needed by defining your own destructor" Is this correct?

• How to configure IIS to serve my 404 response with my custom content?

  - by Marek

  This question is related to this, hopefully better phrased. I would like to serve a custom 404 page from ASP.NET MVC. I have the route handler and all the infrastructure set up to ensure that nonexistent routes are handled by a single action: public ActionResult Handle404() { Response.StatusCode = 404; return View("NotFound"); } Problem: IIS serves back its own content (some predefined message) when I set Response.StatusCode to 404 before returning the content. On the VS development web server, this works as intended - the status code of the HTTP response is 404 while my content (the NotFound view) is served. I believe that when the IIS processing pipeline sees that the application returns 404, it simply replaces the whole response with its own. What setting in IIS affects this behavior? I do not have access to the IIS installation so I can not investigate this - however, I can ask the hosting provider to tweak the configuration for me if I know what exactly needs to be changed.
