  • jQuery + InnovaStudio WYSIWYG Editor

    - by Phil Sturgeon
    I am trying to avoid hard-coding each instance of this WYSIWYG editor so I am using jQuery to create an each() loop based on function name. Annoyingly InnovaStudio seems to explode when I try. Documentation Attempt #1 <script type="text/javascript"> /* id = $(this).attr('id'); if(id.length == 0) { id = 'wysiwyg-' + wysiwyg_count; $(this).attr('id', id); } WYSIWYG[wysiwyg_count] = new InnovaEditor('WYSIWYG[' + wysiwyg_count + ']'); WYSIWYG[wysiwyg_count].REPLACE(id); */ var demo = new InnovaEditor('demo'); demo.REPLACE('wysiwyg-1'); console.log('loop'); </script> Effect Works fine, but of course only works for a single instance of the editor. If I want multiple instances I need to use an each. Attempt #2: <script type="text/javascript"> var wysiwyg_count = 1; //var WYSIWYG = []; var demo; (function($) { $(function() { $('.wysiwyg-simple').each(function(){ /* id = $(this).attr('id'); if(id.length == 0) { id = 'wysiwyg-' + wysiwyg_count; $(this).attr('id', id); } WYSIWYG[wysiwyg_count] = new InnovaEditor('WYSIWYG[' + wysiwyg_count + ']'); WYSIWYG[wysiwyg_count].REPLACE(id); */ demo = new InnovaEditor('demo'); demo.REPLACE('wysiwyg-1'); console.log('loop'); }); }); })(jQuery); </script> Effect Replaces the entire HTML body of my page with JUST WYSIWYG related code and complains as no JS is available (not even Firebug, so can't debug). Does anybody know what the hell is going on here?

  • Help me understand these generic method warnings

    - by Raj
    Folks, I have a base class, say: public class BaseType { private String id; ... } and then three subclasses: public class TypeA extends BaseType { ... } public class TypeB extends BaseType { ... } public class TypeC extends BaseType { ... } I have a container class that maintains lists of objects of these types: public class Container { private List<TypeA> aList; private List<TypeB> bList; private List<TypeC> cList; // finder method goes here } And now I want to add a finder method to container that will find an object from one of the lists. The finder method is written as follows: public <T extends BaseType> T find( String id, Class<T> clazz ) { final List<T> collection; if( clazz == TypeA.class ) { collection = (List<T>)aList; } else if( clazz == TypeB.class ) { collection = (List<T>)bList; } else if( clazz == TypeC.class ) { collection = (List<T>)cList; } else return null; for( final BaseType value : collection ) { if( value.getId().equals( id ) ) { return (T)value; } } return null; } My question is this: If I don't add all the casts to T in my finder above, I get compile errors. I think the compile should be able to infer the types based on parametrization of the generic method (). Can anyone explain this? Thanks. -Raj

  • ASP.NET file transfer from local machine to another machine

    - by Imcl
    I basically want to transfer a file from the client to the file storage server without actual login to the server so that the client cannot access the storage location on the server directly. I can do this only if i manually login to the storage server through windows login. I dont want to do that. This is a Web-Based Application. Using the link below, I wrote a code for my application. I am not able to get it right though, Please refer the link and help me ot with it... http://stackoverflow.com/questions/263518/c-uploading-files-to-file-server The following is my code:- protected void Button1_Click(object sender, EventArgs e) { filePath = FileUpload1.FileName; try { WebClient client = new WebClient(); NetworkCredential nc = new NetworkCredential(uName, password); Uri addy = new Uri("\\\\192.168.1.3\\upload\\"); client.Credentials = nc; byte[] arrReturn = client.UploadFile(addy, filePath); Console.WriteLine(arrReturn.ToString()); } catch (Exception ex) { Console.WriteLine(ex.Message); } } The following line doesn't execute... byte[] arrReturn = client.UploadFile(addy, filePath); This is the error I get: An exception occurred during a WebClient request

  • ICollectionView.SortDescriptions sort does not work if underlying DataTable has zero rows

    - by BigBlondeViking
    We have a WPF app that has a DataGrid inside a ListView. private DataTable table_; We do a bunch or dynamic column generation ( depending on the report we are showing ) We then do the a query and fill the DataTable row by row, this query may or may not have data.( not the problem, an empty grid is expected ) We set the ListView's ItemsSource to the DefaultView of the DataTable. lv.ItemsSource = table_.DefaultView; We then (looking at the user's pass usage of the app, set the sort on the column) Sort Method below: private void Sort(string sortBy, ListSortDirection direction) { ICollectionView dataView = CollectionViewSource.GetDefaultView(lv.ItemsSource); dataView.SortDescriptions.Clear(); var sd = new SortDescription(sortBy, direction); dataView.SortDescriptions.Add(sd); dataView.Refresh(); } In the Zero DataTable rows scenario, the sort does not "hold"? and if we dynamically add rows they will not be in sorted order. If the DataTable has at-least 1 row when the sort is applied, and we dynamically add rows to the DataTable, the rows com in sorted correctly. I have built a standalone app that replicate this... It is an annoyance and I can add a check to see if the DataTable was empty, and re-apply the sort... Anyone know whats going on here, and am I doing something wrong? FYI: What we based this off if comes from the MSDN as well: http://msdn.microsoft.com/en-us/library/ms745786.aspx

  • System Tray Popup Windows 7 Style

    - by Mason Blier
    Hey All, I want something like this: http://cybernetnews.com/wp-content/uploads/2008/10/windows-7-wireless.jpg This window is not resizable, and aligns itself above the system tray icon which it is related to. I have this: http://i.imgur.com/79FZi.png Which is resizeable, and it goes wherever it feels like. If you click the volume control in Win 7, it always pops up directly above the icon. This is ideal. I've found this reference which I think is trying to solve the same problem (can't tell though as the images are dead), http://stackoverflow.com/questions/2169006/create-a-system-tray-styled-box-in-winforms-c but I'm using WPF and I'm not sure how to get these Form objects they refer to from my Window object. This is the XAML declaration of my window atm, <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" x:Class="WirelessControl.Window1" x:Name="Window" Title="Window1" Width="260" Height="370" mc:Ignorable="d" WindowStyle="None"></Window> I feel like based on how common this is in Windows that there must be a fairly easy way to do this. ResizeMode="NoResize" causes my window border to disappear, so that's no help. Thanks guys, I hope I was comprehensive enough.

  • Chart controls for ASP.NET

    - by tolism7
    I am looking people's opinion and experience on using chart controls within an ASP.NET application (web forms or MVC) primarily but also in any kind of project. I am currently doing my research and I have a pretty big list of controls to evaluate. My list includes (in no particular order): ASP.NET controls: DevExpress XtraCharts (http://demos.devexpress.com/XtraChartsDemos/) Dundas Chart for .NET (http://www.dundas.com/) Telerik RadChart for ASP.NET AJAX (http://www.telerik.com/) ComponentArt Charting & Visualization for ASP.NET (http://www.componentart.com/) Infragistics WebChart (http://www.infragistics.com/dotnet/netadvantage/aspnet.aspx#Overview) .net Charting (http://www.dotnetcharting.com/) Chart Control for .Net Framework (Microsoft's) (http://weblogs.asp.net/scottgu/archive/2008/11/24/new-asp-net-charting-control-lt-asp-chart-runat-quot-server-quot-gt.aspx) Flash controls: FusionCharts v3 (http://www.fusioncharts.com/) XML/SWF Charts (http://www.maani.us/xml%5Fcharts/index.php) amCharts (http://www.amcharts.com/) AnyChart (http://www.anychart.com/home/) Javascript: Flot (http://code.google.com/p/flot/) Flotr (http://solutoire.com/flotr/) jqPlot (http://www.jqplot.com/index.php) (If I missed some that worth to be compared against the above please let me know.) What I am looking is opinions on using any of the above so I can form my own and help others do the same, based on what I read here. I do not care which one is better. What I care for is why someone likes one of the above and what do these controls offer as a distinct advantage. I am interested in developer's opinion and I would like to find out which things are difficult doing with any of the above controls and which things are easy to achieve. AJAX compatibility (build in to the controls but also manual), ASP.NET compatibility, input capabilities, data binding options, performance, how much code does one need to write in order to create a chart, are some of the things that I would want to read about. I have already done my research on StackOverflow for relevant questions but there is nothing on the level of detail that I would want to read in order to make a responsible decision.

  • [NSLocale currentLocale] always returns "en_US" not user's current language

    - by Prairiedogg
    I'm in the processes of internationalizing an iPhone app - I need to make programmatic changes to certain views based on what the user's current locale is. I'm going nuts because no matter what the language preference on the iPhone simulator or actual hardware are, locale always evaluates to "en_US": NSString *locale = [[NSLocale currentLocale] localeIdentifier]; NSLog(@"current locale: %@", locale); The crazy thing is that the rest of the application behaves as expected. The correct strings are selected from the Localization.strings file and used in the interface, and the correct .xib files for the selected locale are used. I have also tried the following, to no avail and with the same result: NSString *locale = [[NSLocale autoupdatingCurrentLocale] localeIdentifier]; NSLog(@"current locale: %@", locale); Is there something simple I'm missing? A preference or an import perhaps? Update: As Darren's answer suggests, the preference I'm looking for is not in NSLocale, rather it is here: NSUserDefaults* defs = [NSUserDefaults standardUserDefaults]; NSArray* languages = [defs objectForKey:@"AppleLanguages"]; NSString* preferredLang = [languages objectAtIndex:0]; NSLog(@"preferredLang: %@", preferredLang);

  • What's the "best" database for embedded?

    - by mawg
    I'm an embedded guy, not a database guy. I've been asked to redesign an existing system which has bottlenecks in several places. The embedded device is based around an ARM 9 processor running at 220mHz. There should be a database of 50k entries (may increase to 250k) each with 1k of data (max 8 filed). That's approximate - I can try to get more precise figures if necessary. They are currently using SqlLite 2 and planning to move to SqlLite 3. Without starting a flame war - I am a complete d/b newbie just seeking advice - is that the "best" decision? I realize that this might be a "how long is a piece of string?" question, but any pointers woudl be greatly welcomed. I don't mind doing a lot of reading & research, but just hoped that you could get me off to a flying start. Thanks. p.s Again, a total rewrite, might not even stick with embedded Linux, but switch to eCos, don't worry too much about one time conversion between d/b formats. Oh, and accesses should be infrequent, at most one every few seconds. edit: ok, it seems they have 30k entries (may reach 100k or more) of only 5 or 6 fields each, but at least 3 of them can be a search key for a record. They are toying with "having no d/b at all, since the data are so simple", but it seems to me that with multiple keys, we couldn't use fancy stuff like a quicksort() type search (recursive, binary search). Any thoughts on "no d/b", just data-structures? Btw, one key is 800k - not sure how well SqlLite handles that (maybe with "no d/b" I have to hash that 800k to something smaller?)

  • Sync Vs. Async Sockets Performance in C#

    - by Michael Covelli
    Everything that I read about sockets in .NET says that the asynchronous pattern gives better performance (especially with the new SocketAsyncEventArgs which saves on the allocation). I think this makes sense if we're talking about a server with many client connections where its not possible to allocate one thread per connection. Then I can see the advantage of using the ThreadPool threads and getting async callbacks on them. But in my app, I'm the client and I just need to listen to one server sending market tick data over one tcp connection. Right now, I create a single thread, set the priority to Highest, and call Socket.Receive() with it. My thread blocks on this call and wakes up once new data arrives. If I were to switch this to an async pattern so that I get a callback when there's new data, I see two issues The threadpool threads will have default priority so it seems they will be strictly worse than my own thread which has Highest priority. I'll still have to send everything through a single thread at some point. Say that I get N callbacks at almost the same time on N different threadpool threads notifying me that there's new data. The N byte arrays that they deliver can't be processed on the threadpool threads because there's no guarantee that they represent N unique market data messages because TCP is stream based. I'll have to lock and put the bytes into an array anyway and signal some other thread that can process what's in the array. So I'm not sure what having N threadpool threads is buying me. Am I thinking about this wrong? Is there a reason to use the Async patter in my specific case of one client connected to one server?

  • Does Google Maps API v3 allow larger zoom values ?

    - by Dr1Ku
    If you use the satellite GMapType using this Google-provided example in v3 of the API, the maximum zoom level has a scale of 2m / 10ft , whereas using the v2 version of another Google-provided example (had to use another one since the control-simple doesn't have the scale control) yields the maximum scale of 20m / 50ft. Is this a new "feature" of v3 ? I have to mention that I've tested the examples in the same GLatLng regions - so my guess is that tile detail level doesn't influence it, am I mistaken ? As mentioned in another question, v3 is to be considered of very Labs-y/beta quality, so use in production should be discouraged for the time being. I've been drawn to the subject since I have to "increase the zoom level of a GMap", the answers here seem to suggest using GTileLayer, and I'm considering GMapCreator, although this will involve some effort. What I'm trying to achieve is to have a larger zoom level, a scale of 2m / 10ft would be perfect, I have a map where the tiles aren't that hi-res and quite a few markers. Seeing that the area doesn't have hi-res tiles, the distance between the markers is really tiny, creating some problematic overlapping. Or better yet, how can you create a custom Map which allows higher zoom levels, as by the Google Campus, where the 2m / 10ft scale is achieved, and not use your own tileserver ? I've seen an example on a fellow Stackoverflower's GMaps sandbox , where the tiles are manually created based on the zoom level. I don't think I'm making any more sense, so I'm just going to end this big question here, I've been wondering around trying to find a solution for hours now. Hope that someone comes to my aid though ! Thank you in advance !

  • wxOSX/Carbon: wxGLCanvas mouse offset in non-floating window classes

    - by srose
    Hi All, I mainly program plugins using wxWidgets within a Carbon bundle which is loaded at runtime. The host-applications where my plugins are running in provide a native window handle (WindowRef), which I can use to add my custom, wxWidgets-based GUI-classes. To use the native window handle with wxWidgets classes I had to write a wxTopLevelWindow wrapper class, which does all the WindowRef encapsulation. So far, this works pretty well, but under some circumstances I got vertical mouse offsets within a wxGLCanvas if the window class of the native window handle is not of the type "kFloatingWindowClass". I am able to bypass the problem if I display an info panel (wxPanel) over the whole wxGlCanvas and if the user hides the info panel then the mouse offset is gone. Now my questions: Is there a "simple" explanation for this behaviour? Is it possible to use certain method calls to imitate info panel effect without using the panel itself? I tried several combinations of Update() and Refresh() calls of all involved components, but none of them worked so far. Even the use of wxSizer couldn't help here. Window hierarchy used by plugin-applications: wxCustomTopLevelWindow (WindowRef provided by host-application) wxPanel (parent window for all application panel) wxPanel (application info panel) wxPanel (application main panel) wxPanel (opengl main panel) wxGlCanvas (main opengl canvas) Any ideas? Any help is very appreciated.

  • Making a Text-To-Speech Wrapper in Android

    - by John Montgomery
    I am attempting to create a wrapper class for Google Android's Text-To-Speech functionality. However, I'm having trouble finding a way to have the system pause until after the onInit function has finished. Attached at the bottom is something of a solution I created based on what I found here: http://stackoverflow.com/questions/1160876/android-speech-how-can-you-read-text-in-android However, this solution does not seem to work. Any thoughts on why this might not be working, or what would be a good idea in order to make sure that any Speak() calls happen after my onInit() call? public class SpeechSynth implements OnInitListener { private TextToSpeech tts; static final int TTS_CHECK_CODE = 0; private int ready = 0; private ReentrantLock waitForInitLock = new ReentrantLock(); SpeechSynth( Activity screen ) { ready = 0; tts = new TextToSpeech( screen, this ); waitForInitLock.lock(); } public void onInit(int status) { if (status == TextToSpeech.SUCCESS) { ready = 1; } waitForInitLock.unlock(); } public int Speak( String text ) { if( ready == 1 ) { tts.speak(text, TextToSpeech.QUEUE_ADD, null); return 1; } else { return 0; } } } I have been able to make it so that I can pass a string of text through the constructor, then have it played in the onInit() function. However, I would really like to avoid having to destroy and re-create the whole text-to-speech engine every time I need to have my program say something different.

  • problem using getline with a unicode file

    - by hamishmcn
    UPDATE: Thank you to @Potatoswatter and @Jonathan Leffler for comments - rather embarrassingly I was caught out by the debugger tool tip not showing the value of a wstring correctly - however it still isn't quite working for me and I have updated the question below: If I have a small multibyte file I want to read into a string I use the following trick - I use getline with a delimeter of '\0' e.g. std::string contents_utf8; std::ifstream inf1("utf8.txt"); getline(inf1, contents_utf8, '\0'); This reads in the entire file including newlines. However if I try to do the same thing with a wide character file it doesn't work - my wstring only reads to the the first line. std::wstring contents_wide; std::wifstream inf2(L"ucs2-be.txt"); getline( inf2, contents_wide, wchar_t(0) ); //doesn't work For example my if unicode file contains the chars A and B seperated by CRLF, the hex looks like this: FE FF 00 41 00 0D 00 0A 00 42 Based on the fact that with a multibyte file getline with '\0' reads the entire file I believed that getline( inf2, contents_wide, wchar_t(0) ) should read in the entire unicode file. However it doesn't - with the example above my wide string would contain the following two wchar_ts: FF FF (If I remove the wchar_t(0) it reads in the first line as expected (ie FE FF 00 41 00 0D 00) Why doesn't wchar_t(0) work as a delimiting wchar_t of "00 00"? Thank you

  • ILOG CPLEX: how to populate IloLPMatrix while using addGe to set up the model?

    - by downer
    I have a queatoin about IloLPMatrix and addGe. I was trying to follow the example of AdMIPex5.java to generate user defined cutting planes based on the solution to the LP relaxation. The difference is that eh initial MIP model is not read in from a mps file, but set up in the code using methods like addGe, addLe etc. I think this is why I ran into problems while copying the exampe to do the following. IloLPMatrix lp = (IloLPMatrix)cplex.LPMatrixIterator().next(); lp from the above line turns to be NULL. I am wondering 1. What is the relationship between IloLPMatrix and the addLe, addGe commands? I tried to addLPMatrix() to the model, and then used model.addGe methods. but the LPMatrix seems to be empty still. How do I populate the IloLPMatrix of the moel according to the value that I had set up using addGe and addLe. Is the a method to this easily, or do I have to set them up row by row myself? I was doing this to get the number of variables and their values by doing lp.getNumVars(). Is there other methods that I can use to get the number of variables and their values wihout doing these, since my system is set up by addLe, addGe etc? Thanks a lot for your help on this.

  • Disable Razors default .cshtml handler in a ASP.NET Web Application

    - by mythz
    Does anyone know how to disable the .cshtml extension completely from an ASP.NET Web Application? In essence I want to hijack the .cshtml extension and provide my own implementation based on a RazorEngine host, although when I try to access the page.cshtml directly it appears to be running under an existing WebPages razor host that I'm trying to disable. Note: it looks like its executing .cshtml pages under the System.Web.WebPages.Razor context as the Microsoft.Data Database is initialized. I don't even have any Mvc or WebPages dlls referenced, just System.Web.dll and a local copy of System.Web.Razor with RazorEngine.dll I've created a new ASP.NET Web .NET 4.0 Application and have tried to clear all buildProviders and handlers as seen below: <system.web> <httpModules> <clear/> </httpModules> <compilation debug="true" targetFramework="4.0"> <buildProviders> <clear/> </buildProviders> </compilation> <httpHandlers> <clear/> <add path="*" type="MyHandler" verb="*"/> </httpHandlers> </system.web> <system.webServer> <modules runAllManagedModulesForAllRequests="true"> <clear/> </modules> <handlers> <clear/> <add path="*" name="MyHandler" type="MyHandler" verb="*" preCondition="integratedMode" resourceType="Unspecified" allowPathInfo="true" /> </handlers> </system.webServer> Although even with this, when I visit any page.cshtml page it still bypasses My wildcard handler and tries to execute the page itself. Basically I want to remove all traces of .cshtml handlers/buildProviders/preprocessing so I can serve the .cshtml pages myself, anyone know how I can do this?

  • Structuring projects & dependencies of large winforms applications in C#

    - by Benjol
    UPDATE: This is one of my most-visited questions, and yet I still haven't really found a satisfactory solution for my project. One idea I read in an answer to another question is to create a tool which can build solutions 'on the fly' for projects that you pick from a list. I have yet to try that though. How do you structure a very large application? Multiple smallish projects/assemblies in one big solution? A few big projects? One solution per project? And how do you manage dependencies in the case where you don't have one solution. Note: I'm looking for advice based on experience, not answers you found on Google (I can do that myself). I'm currently working on an application which has upward of 80 dlls, each in its own solution. Managing the dependencies is almost a full time job. There is a custom in-house 'source control' with added functionality for copying dependency dlls all over the place. Seems like a sub-optimum solution to me, but is there a better way? Working on a solution with 80 projects would be pretty rough in practice, I fear. (Context: winforms, not web) EDIT: (If you think this is a different question, leave me a comment) It seems to me that there are interdependencies between: Project/Solution structure for an application Folder/File structure Branch structure for source control (if you use branching) But I have great difficulty separating these out to consider them individually, if that is even possible. I have asked another related question here.

  • File not found on RSACryptoServiceProvider, service account permissions?

    - by Ben Scheirman
    Our web service wraps around a third party library that contains the following code. We are using an Active Directory service account in the IIS 6 app pool (no interactive login abilities). Our service fails with the error “The system cannot find the file specified”. We’ve traced the error to the “RSACryptoServiceProvider provider = new RSACryptoServiceProvider();”. The third party assembly depends on a x509 file based certificate for its encryption process and the Service Account has Read / Write access to the keys folder. Additionally, the service account has Read, Write, Modify rights to “C:\Documents and Settings\All Users\Application Data\Microsoft\Crypto\RSA\MachineKeys”. Code: StringBuilder builder = new StringBuilder(publicKeyData); builder.Replace("-----BEGIN CERTIFICATE-----", ""); builder.Replace("-----END CERTIFICATE-----", ""); X509Certificate2 certificate = new X509Certificate2( Convert.FromBase64String(builder.ToString())); string xmlString = certificate.PublicKey.Key.ToXmlString(false); RSACryptoServiceProvider provider = new RSACryptoServiceProvider(); //BOOM CspKeyContainerInfo containerInfo = provider.CspKeyContainerInfo; provider.PersistKeyInCsp = false; provider.FromXmlString(xmlString); loadedKeys.Add(key, provider); provider2 = provider; We cracked open FileMon and noticed that there is a FILE NOT FOUND for that AppPool, followed by another SUCCESS for the same exact file. I'm out of my element here, anybody have an idea as to why we're seeing this?

  • Rails App hangs after few requests

    - by Paddy
    I have Bitnami Rails stack installed on my Mac. To better explain my problem i created a simple scaffold based rails app with mysql as the backend. I can get to perform simple POST and GET requests for a while and after a few requests the app just hangs indefinitely. No exception caught or anything worthwhile in the development log to report this strange behavior. This is the last bit from the development log before the app froze: Processing WritedatasController#index (for 127.0.0.1 at 2010-03-30 20:38:51) [GET] [4;36;1mWritedata Load (0.7ms) [0m [0;1mSELECT * FROM `writedatas` [0m Rendering template within layouts/application Rendering writedatas/index [4;35;1mWritedata Columns (2.9ms) [0m [0mSHOW FIELDS FROM `writedatas` [0m Completed in 99ms (View: 88, DB: 4) | 200 OK [http://localhost/writedatas] [4;36;1mSQL (0.2ms) [0m [0;1mSET NAMES 'utf8' [0m [4;35;1mSQL (0.1ms) [0m [0mSET SQL_AUTO_IS_NULL=0 [0m Processing WritedatasController#new (for 127.0.0.1 at 2010-03-30 20:38:52) [GET] [4;36;1mWritedata Columns (2.0ms) [0m [0;1mSHOW FIELDS FROM `writedatas` [0m Rendering template within layouts/application Rendering writedatas/new Rendered writedatas/_form (5.9ms) Completed in 34ms (View: 25, DB: 2) | 200 OK [http://localhost/writedatas/new] [4;36;1mSQL (0.4ms) [0m [0;1mSET NAMES 'utf8' [0m [4;35;1mSQL (0.1ms) [0m [0mSET SQL_AUTO_IS_NULL=0 [0m Processing WritedatasController#index (for 127.0.0.1 at 2010-03-30 20:39:17) [GET] [4;36;1mWritedata Load (0.7ms) [0m [0;1mSELECT * FROM `writedatas` [0m Rendering template within layouts/application Rendering writedatas/index [4;35;1mWritedata Columns (2.6ms) [0m [0mSHOW FIELDS FROM `writedatas` [0m Completed in 101ms (View: 90, DB: 4) | 200 OK [http://localhost/writedatas] It just hung at this point. And after this happens i have to restart the server, for it to hang again after few requests. This is the weirdest problem i have faced and i am truly stumped.

  • WPF Memory Leak on XP (CMilChannel, HWND)

    - by vanja.
    My WPF application leaks memory at about 4kb/s. The memory usage in Task Manager climbs constantly until the application crashes with an "Out of Memory" exception. By doing my own research I have found that the problem is discussed here: http://stackoverflow.com/questions/801589/track-down-memory-leak-in-wpf and #8 here: http://blogs.msdn.com/jgoldb/archive/2008/02/04/finding-memory-leaks-in-wpf-based-applications.aspx The problem described is: This is a leak in WPF present in versions of the framework up to and including .NET 3.5 SP1. This occurs because of the way WPF selects which HWND to use to send messages from the render thread to the UI thread. This sample destroys the first HWND created and starts an animation in a new Window. This causes messages sent from the render thread to pile up without being processed, effectively leaking memory. The solution offered is: The workaround is to create a new HwndSource first thing in your App class constructor. This MUST be created before any other HWND is created by WPF. Simply by creating this HwndSource, WPF will use this to send messages from the render thread to the UI thread. This assures all messages will be processed, and that none will leak. But I don't understand the solution! I have a subclass of Application that I am using and I have tried creating a window in that constructor but that has not solved the problem. Following the instructions given literally, it looks like I just need to add this to my Application constructor: new HwndSource(new HwndSourceParameters("MyApplication"));

  • Scroll Position in a Table Body

    - by Craig Walker
    I want to implement infinite scrolling (with an AJAX-based loader) in an HTML table body. My HTML looks something like this: <table> <thead> <tr><th>Column</th></tr> </thead> <tbody> <tr><td>Row 1</td></tr> <tr><td>Row 2</td></tr> </tbody> </table> I get a scroll bar on the <tbody> like so: tbody { height:10em; /* Otherwise the tbody expands to fit all rows */ overflow:auto; } To be able to do anything when the user scrolls to the bottom, I need to be able to get the scroll position of the <tbody>. In all of the (jQuery) infinite scroll implementations I've seen (such as this one), they subtract the content height from the container height and compare it to the .scrollTop() value. Unfortunately this may not work with <tbody>, which is both the viewport and the container for the scrolled content. $("tbody").height() returns the viewable (ie: "shrunken") size, but I don't know how I can get the full (viewable + hidden) size of the table body. (FWIW, $("tbody").scrollTop() returns a "large" number when scrolled to the bottom, exactly as I would expect it to). Is there any way to accomplish this?

  • MVVM Binding Selected RadOutlookBarItem

    - by Christian
    Imagine: [RadOutlookBarItem1] [RadOutlookBarItem2] [RadOutlookBar] [CONTENCONTROL] What i want to achieve is: User selects one of the RadOutlookBarItem's. Item's tag is bound like: Tag="{Binding SelectedControl, Mode=TwoWay}" MVVM Property public string SelectedControl { get { return _showControl; } set { _showControl = value; OnNotifyPropertyChanged("ShowControl"); } } ContentControl has multiple CustomControls and Visibility of those is bound like: <UserControl.Resources> <Converters:BoolVisibilityConverter x:Key="BoolViz"/> </UserControl.Resources> <Grid x:Name="LayoutRoot" Background="White"> <Views:ViewDocumentSearchControl Visibility="{Binding SelectedControl, Converter={StaticResource BoolViz}, ConverterParameter='viewDocumentSearchControl'}"/> <Views:ViewStartControl Visibility="{Binding SelectedControl, Converter={StaticResource BoolViz}, ConverterParameter='viewStartControl'}"/> </Grid> Converter: public object Convert(object value, Type targetType, object parameter, CultureInfo culture) { // here comes the logic part... should return Visibility.Collapsed : Visibility.Visible based on 'object value' value System.Diagnostics.Debugger.Break(); return Visibility.Collapsed; } now, logically the object value is always set to null. So here's it comes to my question: How can i put a value into the SelectedControl Variable for the RadOutlookBarItem's Tag. I mean something like Tag="{Binding SelectedControl, Mode=TwoWay, VALUE='i.e.ControlName'"} So that i can decide, using the Convert Method, whether a specific Control's visibility is either set to collapsed or visible? help's appreciated Christian

  • QFileDialog filter from mime-types

    - by Mathias
    I want the filter in a QFileDialog to match all audio file types supported by Phonon on the platform in question. 1 - However I am not able to find a way in Qt to use mime types in a filter. How can I do that? 2 - Or how can I find the corresponding file extensions for the mimetypes manually? The solution should be Qt based, or at least be cross platform and supported everywhere Qt is. Following is a short code describing my problem: #include <QApplication> #include <QFileDialog> #include <QStringList> #include <phonon/backendcapabilities.h> QString mime_to_ext(QString mime) { // WHAT TO REALLY DO ?? // NEEDLESS TO SAY; THIS IS WRONG... return mime.split("/").back().split('-').back(); } int main(int argc, char **argv) { QApplication app(argc, argv); QStringList p_audio_exts; QStringList p_mime_types = Phonon::BackendCapabilities::availableMimeTypes(); for(QStringList::iterator i = p_mime_types.begin(), ie = p_mime_types.end(); i != ie; i++) { if((*i).startsWith("audio")) p_audio_exts << mime_to_ext(*i); } QString filter = QString("All Files(*)"); if(!p_audio_exts.isEmpty()) { QString p_audio_filter = QString("Audio Files (*.%1)").arg(p_audio_exts.join(" *.")); filter = QString("%1;;%2").arg(p_audio_filter).arg(filter); } QFileDialog dialog(NULL, "Open Audio File", QString::null, filter); dialog.exec(); }

  • Measuring text with sizeWithFont returns height one line too short

    - by Mac
    In an iPhone app I'm working on, I'm trying to get a UILabel to dynamically adjust its size based on its content. To do so, I'm using NSString's sizeWithFont:constrainedToSize method to measure the height of the text when constrained to a given width, and then set the UILabel to that width and the returned height. The problem however, is that roughly half the time sizeWithFont is returning a height for the text that is one line too short. This happens mostly with long strings (a couple of hundred characters), but also very occasionally with shorter strings (less than one hundred). For reference, my code looks like the following (textLabel is the UILabel in question and is a member variable, TEXT_WIDTH is the desired label width): - (void) setLabelText:(NSString*) text { CGSize bounds = CGSizeMake(TEXT_WIDTH, CGFLOAT_MAX); int textHeight = [text sizeWithFont:textLabel constrainedToSize:bounds lineBreakMode:UILineBreakModeWordWrap].height; CGRect newFrame = CGRectMake(0, 0, TEXT_WIDTH, textHeight); [textLabel setFrame:newFrame]; } Just to be clear, I don't believe the issue is with the UILabel, as I've manually inspected the value being returned by sizeWithFont and can confirm that the number being returned for the height is too small on the occasions when the label is also too small.
