• Need help using ThemeRoller

  - by Music Magi

  Hi - I'm using DataTables to dress up a table I'm using to display XML results based on an XSL transformation. I have everything working from a technical sense (paging, sorting, filtering), but I'm trying to figure out to use a ThemeRoller theme to make it look like they have on their website. So far, I have added the following file to my project with its reference: <link type="text/css" href="css/custom-theme/jquery-ui-1.8.7.custom.css" rel="stylesheet"/> and enabled ThemeRoller themes using the following as per the DataTables website: $(document).ready(function() { $('#mainTable').dataTable( { "bJQueryUI": true, "sPaginationType": "two_button" }); }); The table gets styled, but it doesn't look right with the header rows being too wide and things being on multiple lines that should be on one line. Any indication as to what I'm doing wrong? Thanks very much in advance.

• How can i see if dealloc is being called on a uikit object, or any object not created by myself

  - by Gyozo Kudor

  I think i have an UIImage that has a higher retain count than it should have and i am probably leaking memory. I use this image as a thumbnail, to set a custom background to a uibutton. So the uibutton is holding a reference to it and so do i. But instead of 2, the retainCount is 3. Do i have to create a custom UIImage derived class and override dealloc if I want to place a log message there and then change the class used from UIImage to my class, or is there an easier way. Thanks in advance.

• ASP.NET application stopping event?

  - by Barguast

  I have a ASP.NET application which implements a custom in-memory cache. I'm using this as opposed to ASP.NET's caching mechanism as I needed a more complex way to handle what to drop from the cache. Part of this custom cache is a separate thread which occasionally searches for data to drop from the cache whenever it gets too large. What I need to do is signal this cache maintenance thread to stop whenever the ASP.NET application 'exits'. I guess this basically amounts to when the web site is stopped in IIS. Is there a pre-existing event I can utilise to do this? Thanks.

• Needed environment for building gstreamer plugins in Windows

  - by utnapistim

  Hi, I've been strugling for two weeks to create an environment for building a gstreamer plugin on windows (needed for a songbird addon). I've installed MSYS, MinGW and Cygwin, then installed GStreamer OSSBuild, and I also downloaded the sources for Songbird, which come with their own precompiled version of gstreamer. I was unable to run gst-inspect (or any other gstreamer applications) from the songbird sources and I figured I will settle for OSSBuild. When following the instructions for building a GST plugin (found here) through, cygwin will not recognize the OSSBuild and the build fails when running autogen, with the following error: checking for GST... no configure: error: You need to install or upgrade the GStreamer development packages on your system. On debian-based systems these are libgstreamer0.10-dev and libgstreamer-plugins-base0.10-dev. on RPM-based systems gstreamer0.10-devel, libgstreamer0.10-devel or similar. The minimum version required is 0.10.16. configure failed I could also not use MSYS or MinGW as they are unable to run autogen at all. I understand that cygwin should have it's own gstreamer development packages but I couldn't find how to install them. My question: How do I install the gstreamer packages in cygwin or how do I build using cygwin with the OSSBuild dependencies? In short, how do I get an environment where I can build a gstreamer plugin under windows?

• Jquery: Calling functions from different documents

  - by Tom

  Hi, I've got some Jquery functions that I keep in a "custom.js" file. On some pages, I need to pass PHP variables to the Jquery so some Jquery bits need to remain in the HTML documents. However, as I'm now trying to refactor things to the minimum, I'm tripping over the following: If I put this in my custom.js: $(document).ready(function() { function sayHello() { alert("hello"); } } And this in a HTML document: <script type="text/javascript"> $(document).ready(function() { sayHello(); }); </script> ... the function doesn't get called. However, if both are placed in the HTML document, the function works fine. Is there some kind of public property I need to declare for the function or how do I get Jquery functions in my HTML to talk to external .js files? They're correctly included and work fine otherwise. Thanks.

• jQuery Validation 1.10 and MVC server-side errors

  - by sam360

  This feature used to work just fine on my website. If I added a custom error to ModelState, the input on the page would be marked as "input-validation-error" and the Html.ValidationMessage() would take care of rendering a span with the error message inside it. Due to incompatibility reasons we had to upgrade our jQuery Validation to 1.10: Now when I add a custom error to ModelState, I can debug and see that the HTML elements being rendered correctly, but as soon as the page load is completed, jQuery Validation removes the error message and set the "class" attribute of the input to "valid"! Has any one else come across this issue? UPDATE Testing further shows that the error message is shown on the screen until the field gains focus. As soon as the field gains focus jQuery Validation removes the customer server-side error message and marks the field as good.

• Project management and bundling dependencies

  - by Joshua

  I've been looking for ways to learn about the right way to manage a software project, and I've stumbled upon the following blog post. I've learned some of the things mentioned the hard way, others make sense, and yet others are still unclear to me. To sum up, the author lists a bunch of features of a project and how much those features contribute to a project's 'suckiness' for a lack of a better term. You can find the full article here: http://spot.livejournal.com/308370.html In particular, I don't understand the author's stance on bundling dependencies with your project. These are: == Bundling == Your source only comes with other code projects that it depends on [ +20 points of FAIL ] Why is this a problem, (especially given the last point)? If your source code cannot be built without first building the bundled code bits [ +10 points of FAIL ] Doesn't this necessarily have to be the case for software built against 3rd party libs? Your code needs that other code to be compiled into its library before the linker can work? If you have modified those other bundled code bits [ +40 points of FAIL ] If this is necessary for your project, then it naturally follows that you've bundled said code with yours. If you want to customize a build of some lib,say WxWidgets, you'll have to edit that projects build scripts to bulid the library that you want. Subsequently, you'll have to publish those changes to people who wish to build your code, so why not use a high level make script with the params already written in, and distribute that? Furthermore, (especially in a windows env) if your code base is dependent on a particular version of a lib (that you also need to custom compile for your project) wouldn't it be easier to give the user the code yourself (because in this case, it is unlikely that the user will already have the correct version installed)? So how would you respond to these comments, and what points may I be failing to take into consideration? Would you agree or disagree with the author's take (or mine), and why?

• A Newbie question regarding Software Development

  - by Sharif

  Hi, I'm going to complete my B.pharm (Hons.) degree and, you know, I don't have much knowledge about programing. I was wondering to build a software on my own. Could you guys tell me what to learn first for that? Is it too hard for a student of other discipline to build a software? Let me know please. The software I want to make is like a dictionary (or more specifically like "Physician's Desk Reference"). It should find the generic name, company name, indication, price etc. of a drug when I enter the brand name and vice versa. To build a software like that what programing language could help me most and what (and how many) language should I learn first? In my country, there is no practice of Community pharmacy (most of the pharmacy stores are run by unskilled people), that's why this type of thing could help them sell drugs. Would you please tell me what I'm to do and how tough it is? I'm very keen to learn programming. Thanks in advance NB: I started this post in ASKREDDIT section but it seems that was not the right place for poll type question, so I post it again in this section

• Obtaining reference to Class instance by string name - VB.NET

  - by Jeff Williams

  Is it possible using Reflection or some other method to obtain a reference to a specific class instance from the name of that class instance? For example the framework for the applications i develop heavily uses public class instances such as: Public bMyreference as MyReference = new MyReference Then throughout the application bMyReference is used by custom controls and code. One of the properties of the custom controls is the "FieldName" which references a Property in these class instances (bMyReference.MyField) as a string. What i would like to be able to do is analyze this string "bMyReference.MyField" and then refer back to the actual Instance/Property. In VB6 I would use an EVAL or something simular to convert the string to an actual object but this obviously doesn't work in VB.net What I'm picturing is something like this Dim FieldName as String = MyControl.FieldName ' sets FielName to bMyReference.MyField Dim FieldObject() as String = FieldName.Split(".") ' Split into the Object / Property Dim myInstance as Object = ......... ' Obtain a reference to the Instance and set as myInstance Dim myProperty = myInstance.GetType().GetProperty(FieldObject(1))

• IKImageView, Buttons work intermittently in 10.5 but ok in 10.6

  - by markhunte

  Hi all, In IB,I have connected some buttons to a IKImageView. Using its received Action 'ZoomIn:', 'ZoomOut:','ZoomImageToActualSize:' When I build for 10.6 I have no issues these work as expected. But in 10.5 (ppc), they sometimes work as expected and sometimes do not. I have even tried it programatically. But I get the same results. It is intermittent with each build after I have made some small change in IB that I need. But not changes that should affect how the view acts. The only buttons that seem to work through out are 'ZoomImageToFit' and the rotate ones. When the do not work as expected, I see no change to the current image in the view, but when my app (/s, I have had this issue before in different apps) changes the image The view reflects the last request from a button. So for example when it does not work. An image is displayed, I click the 'ZoomImageToActualSize:' button, nothing happens. I load a new image and it is displayed at Actual size. Example when it does work. An image is displayed, I click the 'ZoomImageToActualSize:' button, It is displayed at Actual size. By the way, I know I can reset the view default , before I load a new image. Also if I run the 10.5 app in 10.6, it works ok, but as above I get intermittent results with the same build on multible 10.5 machines. Does anyone know what is going on, is this a known bug? Thanks for any help. MH

• Internet Explorer 8 EmulateIE7 Mode not working

  - by Ryu

  I've set up IIS6 to send the following headers Custom Header Name: X-UA-Compatible Custom Header Value: IE=EmulateIE7 that supposed to force IE 8 into IE 7 Compatibility mode. You can read more about it on MSDN . I have noticed by looking in the Developer toolbar that if I have a DTD defined the document mode correctly gets set to IE 7, but the browser mode is IE 8. If the page doesn't have a DTD the document mode gets set to Quirks and Browser Mode once again IE 8. Am I doing something wrong. How do I force IE 8 to set IE 7 Browser mode. Thanks

• Retrieve baseUri w/o resorting to Application.Current

  - by beaudetious

  My custom controls are not loading in VS.NET's designer because of a null reference exception. It's got everything to do with the way I am retrieving the baseUri of the application when it runs in the browser: _uriPrefix = Application.Current.Host.Source.AbsoluteUri.Substring(0, Application.Current.Host.Source.AbsoluteUri.IndexOf("/ClientBin")).Trim(); According to the exception details and the help file I'm directed to (here) I'm not correctly designing my app for a runtime that's not the browser (i.e. the new WPF editor in VS.NET or Expression Blend). So, the question is how do retrieve the baseUri (the http://localhost:#### part of my application) if I can't use Application.Host which apparently is null during design time? is there a safe way to do this so I can load my custom controls in a designer?

• Changing where a resource is pulled during runtime?

  - by Brandon

  I have a website that goes out to multiple clients. Sometimes a client will insist on minor changes. For reasons beyond my control, I have to comply no matter how minor the request. Usually this isn't a problem, I would just create a client specific version of the user control or page and overwrite the default one during build time or make a configuration setting to handle it. Now that I am localizing the site, I'm curious about the best way to go about making minor wording changes. Lets say I have a resource file called Resources.resx that has 300 resources in it. It has a resource called Continue. English value is "Continue", the French value is "Continuez". Now one client, for whatever reason, wants it to say "Next" and "Après" and the others want to keep it the same. What is the best way to accomodate a request like this? (This is just a simple example). The only two ways I can think of is to Create another Resources.resx specific to the client, and replace the .dll during build time. Since I'd be completely replacing the dll, the new resource file would have to contain all 300 strings. The obvious problem being that I now have 2 resource files, each with 300 strings to maintain. Create a custom user control/page and change it to use a custom resource file. e.g. SignIn.ascx would be replaced during the build and it would pull its resources from ClientName.resx instead of Resources.resx. Are there any other things I could try? Is there any way to change it so that the application will always look in a ClientResources.resx file for the overridden values before actually look at the specified resource file?

• AnyCPU/x86/x64 for C# application and it's C++/CLI dependency

  - by Soonts

  I'm Windows developer, I'm using Microsoft visual studio 2008 SP1. My developer machine is 64 bit. The software I'm currently working on is managed .exe written in C#. Unfortunately, I was unable to solve the whole problem solely in C#. That's why I also developed a small managed DLL in C++/CLI. Both projects are in the same solution. My C# .exe build target is "Any CPU". When my C++ DLL build target is "x86", the DLL is not loaded. As far as I understood when I googled, the reason is C++/CLI language, unlike other .NET languages, compiles to the native code, not managed code. I switched the C++ DLL build target to x64, and everything works now. However, AFAIK everything will stop working as soon as my client will install my product on a 32-bit OS. I have to support Windows Vista and 7, both 32 and 64 bit versions of each of them. I don't want to fall back to 32 bits. That 250 lines of C++ code in my DLL is only 2% of my codebase. And that DLL is only used in several places, so in the typical usage scenario it's not even loaded. My DLL implements two COM objects with ATL, so I can't use "/clr:safe" project setting. Is there way to configure the solution and the projects so that C# project builds "Any CPU" version, the C++ project builds both 32 bit and 64 bit versions, then in the runtime when the managed .EXE is starting up, it uses either 32-bit DLL or 64-bit DLL depending on the OS? Or maybe there's some better solution I'm not aware of? Thanks in advance!

• ASP.NET MVC submitting json array to controller as regular post request (nonajax)

  - by j3ko

  All the examples of json I can find online only show how to submit json arrays w/ the jquery command $.ajax(). I'm submitting some data from a custom user control as a json array. I was wondering if it's possible to submit a json array as a regular post request to the server (like a normal form) so the browser renders the page returned. Controller: [JsonFilter(Param = "record", JsonDataType = typeof(TitleViewModel))] public ActionResult SaveTitle(TitleViewModel record) { // save the title. return RedirectToAction("Index", new { titleId = tid }); } Javascript: function SaveTitle() { var titledata = GetData(); $.ajax({ url: "/Listing/SaveTitle", type: "POST", data: titledata, contentType: "application/json; charset=utf-8", }); } Which is called from a save button. Everything works fine but the browser stays on the page after submitting. I was thinking of returning some kind of custom xml from the server and do javascript redirect but it seems like a very hacky way of doing things. Any help would be greatly appreciated.

• If the dependency is a unique snapshot version and install is called, what does maven select?

  - by chrsk

  Imagine two projects. The first is the framework-core project which is in version 1.1.0 and has several snapshot builds. The other is the example-business project which has the following dependency to framework-core on the build-iteration number 9. <dependency> <groupId>org.example</groupId> <artifactId>framework-core</artifactId> <version>1.1.0-20100518.134928-9</version> </dependency> What happens if mvn install is called on the framework-core? I found out that the artifact is copied to the folder and is named to *.1.1.0-SNAPSHOT.jar (as expected). This lead me to the assumption that this version is only used if even this 1.1.0-SNAPSHOT version is defined as dependency and not the precise build. To test something local without deploying it to the maven repository: call mvn install, change the dependency to 1.1.0-SNAPSHOT -- and the artifact just installed is used? Or is it possible to overwrite the specific build (with using the install lifecycle phase)?

• Errors with redefinitions after upgrade to XCode 3.2.3

  - by CA Bearsfan

  I recently upgraded to Snow Leopard and Xcode 3.2.5 so I could test on my iPod Touch and iPhone and ran into some problems with the project I was working on. First it couldn't find a Base SDK, then my old frameworks weren't hooking up correctly. Finally after setting the Project Format to Xcode 3.1 compatible (3.2 also worked) and the Base SDK for all configurations to iOS 4.2, then setting my iOS deployment target to iOS 3.0 I was able to get the system to find a Base SDK and attempt a build. That's when the frameworks didn't want to cooperate. 4/6 I'm using displayed in red, so I re routed the path to the iPhone simulator 4.2 platform which worked perfectly. I was able to build my project, no errors or warnings and my app worked fine. I went to work last night thinking I had fixed the problem. This morning I fired up the laptop and went to build my code base and now have 1142 errors all of which have to do with code I haven't written deemed as being redefined. Suggestions? The following is just a small sample of the error list (obviously don't need to see all 1142) //Frameworks/Foundation.framework/Headers/NSZone.h:48: error: redefinition of 'NSMakeCollectable' /Frameworks/Foundation.framework/Headers/NSObject.h:65: error: duplicate interface declaration for class 'NSObject' /Frameworks/Foundation.framework/Headers/NSObject.h:67: error: redefinition of 'struct NSObject'

• ASF duration is 29 secs, WMP plays 25 secs. How come?

  - by Roey

  Hi All. I've created a custom ASF file containing compressed voice + screen streams. The total duration of the file according to the header is 29 secs. When opening it in WMP (using custom DMOs to play the streams), the file plays 25 seconds, and then the seek bar snaps to the beginning, but oddly, WMP continues to play 4 more seconds before stopping. Looking at the ASF with ASF Viewer - there are 29 seconds of packets , and both "play duration" and "send duration" are 29 seconds. Why would WMP only see 25 seconds?? Thanks

• 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?

• Unable to create a breakpoint in Eclipse and Tomcat

  - by Traroth

  Since yesterday, I get a strange error message when I start my Tomcat (6.0.35) under Eclipse Juno (build 20120614-1722): Among the things I tried in order to get rid of the error: Check in Preferences - Java - Compiler if all "Classfile Generation" checkboxes where checked. I did that for both general preferences and project preference Uncheck them, build, check them build again (found on another question) Add org.eclipse.jdt.core.compiler.debug.lineNumber=generate to my .settings/org.eclipse.jdt.core.prefs file Use a new CVS checkout (same symptoms) And now, I don't know what to do anymore. The problem is really stopping me from get anything done. I can't work anymore. Crazy is: the problem doesn't happen on every class, only on some of them. Neither does it happen on my other Eclipse projects. And it didn't happen before yesterday, even if I can't remeber having done anything weird. Actually, I have never seen a problem like this in almost 10 years I'm using Eclipse... If you have any idea, I would be really grateful... Edit: I also tried to ignore the message and go on with my tests: If I create another breakpoint upstream from my problematic class, when I enter this problematic class, it tries to open a $Proxy132 class, which means it actually opens an empty page, with a source not found message

• Adding a transparent bitmap to a windows button

  - by cmaughan

  It's a while since I've done this, but I'm trying to add a custom button graphic to a windows button, with some transparent areas. I've tried various schemes but can't seem to get the transparent areas to show. Here's my code: hbmpUpDisabled = LoadImage(instance,MAKEINTRESOURCE(IDB_UPARROWDISABLED), IMAGE_BITMAP, 0, 0, LR_DEFAULTSIZE | LR_LOADTRANSPARENT | LR_LOADMAP3DCOLORS ); SendMessage(GetDlgItem(hWndDlg, IDC_MOVEUP),BM_SETIMAGE,(WPARAM)IMAGE_BITMAP,(LPARAM)hbmpUpDisabled); Does anyone notice any problems here? It works if my bitmap is a 1-bit bitmap. I couldn't get a 32 bit bitmap to work, and I'm not sure how to setup a 24 bit or 8 bit bitmap to do it.... I tried a custom 255,0,255 color (which IIRC is a default transparent value), but so far no joy....

• How to protect HtmlHelper code in MVC controls

  - by Oats

  I am writing a custom mvc control (commercial), and all of the control's code lives in the custom htmlhelper code that i will have to distribute to the user. I am ok with this for my commercial license sale, but for evaluating the controls, if i give out the htmlhelper code locally for my potential customers to evaluate, the user can simply "get" all the code and hence he may never buy it since he's got teh control code. How do i protect my htmlhelper code while somebody is evaluation my cusotm mvc controls? Is this a general problem or (I wish) i am missing something here? Thanks.

• IO redirect engine with metadata

  - by hawk.hsieh

  Is there any C library or tool to redirect IO and be able to configured by a metadata. And provide a dynamic link library to perform custom process for feeding data into next IO. For example, network video recorder: record video: socket do_something() file preview video: socket do_something() PCI device http service: download file: socket do_something(http) file socket post file: socket do_something(http) file serial control: monitor device: uart do_something(custom protocol) popen("zip") socket I know the unix-like OS has IO redirect feature and integrate all application you want. Even socket IO you can use /dev/tcp or implement a process to redirect to stdout. But this is process based , the process's foot print is big , IPC is heavy. Therefore, I am looking for something to redirect IO in a process and the data redirect between IO is configurable with a metadata (XML,jason or others).
