• unable to delete file (jpeg)

  - by ile

  I implemented helper for showing thumbnails from here Next to thumbnail, there is delete link which calls this controller // // HTTP POST: /Photo/Delete/1 [AcceptVerbs(HttpVerbs.Post)] public ActionResult Delete(int id, string confirmButton) { var path = "~/Uploads/Photos/"; Photo photo = photoRepository.GetPhoto(id); if (photo == null) return View("NotFound"); FileInfo TheFile = new FileInfo(Server.MapPath(path + photo.PhotoID + ".jpg")); if (TheFile.Exists) { photoRepository.Delete(photo); photoRepository.Save(); TheFile.Delete(); } else return View("NotFound"); return View(); } If I disable showing thumbnails then the file is deleted. Otherwise it sends error: System.IO.IOException: The process cannot access the file 'C:\Documents and Settings\ilija\My Documents\Visual Studio 2008\Projects\CMS\CMS\Uploads\Photos\26.jpg' because it is being used by another process. I also don't know if my file delete function is properly written. Searching on the net, I see everyone uses File.Delete(TheFile);, which i'm unable to use and I use TheFile.Delete(); For File.Delete(TheFile); i get following error: Error 1 'System.Web.Mvc.Controller.File(string, string, string)' is a 'method', which is not valid in the given context C:\Documents and Settings\ilija\My Documents\Visual Studio 2008\Projects\CMS\CMS\Controllers\PhotoController.cs 109 17 CMS Am I missing something here? Thanks in advance

• Facelet does not convert formatted currency correctly

  - by c0d3x

  Hi, I have the follwing code inside a facelet page: <h:inputNumber value="bean.property"> <f:convertNumber type="currency" /> </h:inputNumber The converter is because there can be a kind of default value inside the input field, which comes from the bean property. Everything is rendered correctly. The value inside the input field is rendered with an "€" character (e.g. "1.453 €". When I submit the form there comes an error up: "nameOfInputField" konnte nicht als ein Geldbetrag erkannt werden '304,00 â¬' In english it is some like: "nameOfInputField" could not be regognized as an amount of money '304,00 â¬' Please have a look at the "€" character. It seems to be printed as "â¬". While it was rendered correctly before submitting the form, now it looks like "â¬" inside the error message and inside the input field. All pages are encoded in UTF-8. What is the reason for this error? How can fix it? Thanks in advance

• ListView Parsing Persian xml

  - by Namikaze Minato

  I used a tutorial about listview parsing xm from internet and using LasyAdapter shows the items in listview. When I add persian characters in xml (into one of childnodes) the result is some boxes in listview (after showing the text in listview). The format of xml is UTF-8, too. I used typeface too (but didn't work). Besides when I type Pwesian into the application it shows alright but it can't show Persiann content parsed from xml. Thanks in advance. I updated the post with original XMLparser (which was the problem). public String getXmlFromUrl(String url) { String xml = null; try { // defaultHttpClient DefaultHttpClient httpClient = new DefaultHttpClient(); HttpPost httpPost = new HttpPost(url); HttpResponse httpResponse = httpClient.execute(httpPost); HttpEntity httpEntity = httpResponse.getEntity(); xml = EntityUtils.toString(httpEntity); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } catch (ClientProtocolException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } // return XML return xml; } public Document getDomElement(String xml) { Document doc = null; DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance(); try { DocumentBuilder db = dbf.newDocumentBuilder(); InputSource is = new InputSource(); is.setCharacterStream(new StringReader(xml)); doc = db.parse(is); } catch (ParserConfigurationException e) { Log.e("Error: ", e.getMessage()); return null; } catch (SAXException e) { Log.e("Error: ", e.getMessage()); return null; } catch (IOException e) { Log.e("Error: ", e.getMessage()); return null; } return doc; }

• Group variables in a boxplot in R

  - by tao.hong

  I am trying to generate a boxplot whose data come from two scenarios. In the plot, I would like to group boxes by their names (So there will be two boxes per variable). I know ggplot would be a good choice. But I got errors which I could not figure out. Can anyone give me some suggestions? sensitivity_out1 structure(c(0.0522902104339716, 0.0521369824334004, 0.0520240345973737, 0.0519818337359876, 0.051935071418996, 0.0519089404325544, 0.000392698277338341, 0.000326135474295325, 0.000280863338343747, 0.000259631566041935, 0.000246594043996332, 0.000237923540393391, 0.00046732650331544, 0.000474448907808135, 0.000478287273678457, 0.000480194683464109, 0.000480631753078668, 0.000481760272726273, 0.000947965771207979, 0.000944821699830455, 0.000939631071343889, 0.000937186900570605, 0.000936007346568281, 0.000934756220144141, 0.00132442589501872, 0.00132658367774979, 0.00133334696220742, 0.00133622384928092, 0.0013381577476241, 0.00134005741746304, 0.0991622968751298, 0.100791399440082, 0.101946808417405, 0.102524244727408, 0.102920085260477, 0.103232984259916, 0.0305219507186844, 0.0304635269233494, 0.0304161055015213, 0.0303742106794513, 0.0303381888169022, 0.0302996157711171, 1.94268588634518e-05, 2.23991225564447e-05, 2.5756135487907e-05, 2.79997917298194e-05, 3.00753967077715e-05, 3.16270817369878e-05, 0.544701146678523, 0.542887331601984, 0.541632986366816, 0.541005610554556, 0.540617004208336, 0.540315690692195, 0.000453386694666078, 0.000448473414508756, 0.00044692043197248, 0.000444826296854332, 0.000445747996014684, 0.000444764303682453, 0.000127569551159321, 0.000128422491392669, 0.00012933662856487, 0.000129941842982939, 0.000129578971489026, 0.000131113075233758, 0.00684610571790029, 0.00686349387897349, 0.00687468164010565, 0.00687880720347743, 0.00688275579317197, 0.00687822247621936), .Dim = c(6L, 12L)) out2 structure(c(0.0189965816735366, 0.0189995096225103, 0.0190099362589894, 0.0190033523148514, 0.01900896721937, 0.0190099427513381, 0.00192043989797585, 0.00207303208721059, 0.00225931163225165, 0.0024049969048389, 0.00252310364086785, 0.00262940166568126, 0.00195164921633517, 0.00190079923515755, 0.00186139563778548, 0.00184188171395076, 0.00183248544676564, 0.00182492970673969, 1.83038731485927e-05, 1.98252671720347e-05, 2.14794764479231e-05, 2.30713122969332e-05, 2.4484220713564e-05, 2.55958833705284e-05, 0.0428066864455102, 0.0431686808647809, 0.0434411033615353, 0.0435883377765726, 0.0436690169266633, 0.0437340464360965, 0.145288252474567, 0.141488776430307, 0.138204532539654, 0.136281799717717, 0.134864952272761, 0.133738386148036, 0.0711728636959696, 0.072031388688795, 0.0727536853228245, 0.0731581966147734, 0.0734424337399303, 0.0736637270702609, 0.000605277151497094, 0.000617268349064968, 0.000632975679951382, 0.000643904422677427, 0.000653775268094148, 0.000662225067910141, 0.26735354610469, 0.267515415990146, 0.26753155165617, 0.267553498616325, 0.267532284594615, 0.267510330320289, 0.000334158771646756, 0.000319032383145857, 0.000306074699839994, 0.000299153278494114, 0.000293956197852583, 0.000290171804454218, 0.000645975219899115, 0.000637548672578787, 0.000632375486965757, 0.000629579821884212, 0.000624956458229123, 0.000622456283217054, 0.0645188290106884, 0.0651539609630352, 0.0656417364889907, 0.0658996698322889, 0.0660715073023965, 0.0662034341510152), .Dim = c(6L, 12L)) Melt data: group variable value 1 1 PLDKRT 0 2 1 PLDKRT 0 3 1 PLDKRT 0 4 1 PLDKRT 0 5 1 PLDKRT 0 6 1 PLDKRT 0 Code: #Data_source 1 sensitivity_1=rbind(sensitivity_out1,sensitivity_out2) sensitivity_1=data.frame(sensitivity_1) colnames(sensitivity_1)=main_l #variable names sensitivity_1$group=1 #Data_source 2 sensitivity_2=rbind(sensitivity_out1[3:4,],sensitivity_out2[3:4,]) sensitivity_2=data.frame(sensitivity_2) colnames(sensitivity_2)=main_l sensitivity_2$group=2 sensitivity_pool=rbind(sensitivity_1,sensitivity_2) sensitivity_pool_m=melt(sensitivity_pool,id.vars="group") ggplot(data = sensitivity_pool_m, aes(x = variable, y = value)) + geom_boxplot(aes( fill= group), width = 0.8) Error: "Error in unit(tic_pos.c, "mm") : 'x' and 'units' must have length > 0" Update Figure out the error.

• Authorization and Jquery dialog problem.

  - by bbrepols

  Hi, I have a little problem with a Jquery dialog for an action that requires a role. In my example, the user can click on a delete button and must confirm the action. In my controller, the Delete action requires a role, if the user is in the required role, the object is deleted. The problem: How to alert the user if * the element was deleted (redirect to the Index view) * there was an error (alert with the message) * he doesn't have the rights to delete (alert with the message) Before using the authorize filter, the delete action returned a JSON with a Boolean that indicates if there was an error, an URL to redirect on success and a message to alert on error. As I can't return a JSON from my filter, I created an other method with the authorize filter that returns a partial view with the confirm content. If the user doesn't have the rights, the filter returns a partial view with an unauthorized exception content. The problem: How to distinct which partial view was returned. When I create the dialog, I need to know for the buttons function. Thanks!

• [Zend YouTubeAPP] failed to upgrade a token

  - by kwokwai

  Hi all, I was testing Zend Gdata 1.10.1 in my localhost. I downloaded Zend Gdate from this link: http://framework.zend.com/download/webservices Inside the Zend Gdata zip file, there was a folder called demos. I extracted it and used the YouTudeVideoApp to upload a sample video to Youtube. But every time after I logged into Youtube, before it redirected me to my localhost, I received a warning message like this warning message: localhost: This website is registered with Google to make authorization requests, but has not been configured to send requests securely. We recommend that you continue the process only if you trust the following destination: localhost:8080/youtube/operations.php So I googled on how to resolve the problem of getting this warning message when I saw some people suggesed changing the value of $secure to True in operation.php. Here is the script mentioned: function generateAuthSubRequestLink($nextUrl = null) { $scope = 'http://gdata.youtube.com'; $secure = true; $session = true; if (!$nextUrl) { generateUrlInformation(); $nextUrl = $_SESSION['operationsUrl']; } $url = Zend_Gdata_AuthSub::getAuthSubTokenUri($nextUrl, $scope, $secure, $session); echo '<a href="' . $url . '"><strong>Click here to authenticate with YouTube</strong></a>'; } After I altered the value of $secure to True, I found that the warning message changed to this: localhost: Registered, secure. This website is registered with Google to make authorization requests The new warning message is somehow shorter and looks better than the previous warning message. But once I pressed the Allow Access button, it turned out to be this: ERROR - Token upgrade for CI3M6_Q3EOGkxoL-___wEYjffToQQ failed : Token upgrade failed. Reason: Invalid AuthSub header. Error 401 ERROR - Unknown search type - '' I don't know why this happened. Could you help me solve the problem please?

• How can I implement a volume meter for a song currently playing? (iPhone OS 3.1.3)

  - by Adam

  Hi i'm very new to core audio and I just would like some help in coding up a little volume meter for whatever's being outputted through headphones or built-in speaker. Like a dB meter. I have the following code, and have been trying to go through the apple source project "SpeakHere", but it's a nightmare trying to go through all that, without knowing how it works first... Could anyone shed some light? Here's the code I have so far... (void)displayWaveForm { while (musicIsPlaying == YES { NSLog(@"%f",sizeof(AudioQueueLevelMeterState)); } } (IBAction)playMusic { if (musicIsPlaying == NO) { NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/track7.wav",[[NSBundle mainBundle] resourcePath]]]; NSError *error; music = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error]; music.numberOfLoops = -1; music.volume = 0.5; [music play]; musicIsPlaying = YES; [self displayWaveForm]; } else { [music pause]; musicIsPlaying = NO; } }

• Memory leak when changing Text field of a Scintilla object.

  - by PlaZmaZ

  I have a relatively large program that I'm optimizing for ASCII input files around 10-80mB in size. The program reads every line of the file into a stringbuilder and then sets the Text field of the ScintillNET object to the stringbuilder. The stringbuilder is then set to null. private void ReloadFile(string sFile) { txt_log.ResetText(); try { StringBuilder sLine = new StringBuilder(""); using (StreamReader sr = new StreamReader(sFile)) { while (true) { string temp = sr.ReadLine(); if (temp == null) break; sLine.AppendLine(temp); } sr.Close(); } txt_log.Text = sLine.ToString(); sLine = null; } catch (Exception ex) { MessageBox.Show(this, "An error occurred opening this file.\n\n" + ex.Message, "File Open Error", MessageBoxButtons.OK, MessageBoxIcon.Error); } GC.Collect(); } The program has an option to reload or open a file. This is irrelevant, as any call to txt_log.Text seems to not get rid of the previous memory used for the .Text field. Commenting out the txt_log.Text line gives proper memory behavior. The GC.Collect() line seems pointless, and I have tried both with and without it. Is there something I'm missing here? I HIGHLY doubt it's a problem with the ScintillaNET component itself--rather something in this code.

• eclipse, one classpath for compiling, another for launching

  - by DragonFax

  example: For logging, my code uses log4j. but other jars my code is dependent upon, uses slf4j instead. So both jars must be in the build path. Unfortunately, its possible for my code to directly use (depend on) slf4j now, either by context-assist, or some other developers changes. I would like any use of slf4j to show up as an error, but my application (and tests) will still need it in the classpath when running. explanation: I'd like to find out if this is possible in eclipse. This scenario happens often for me. I'll have a large project, that uses alot of 3rd party libraries. And of course those 3rd party jars have their own dependencies as well. So I have to include all dependencies in the classpath ("build path" in eclipse) for the application and its tests to compile and run (from within eclipse). But I don't want my code to use all of those jars, just the few direct dependencies I've decided upon myself. So if my code accidentally uses a dependency of a dependency, I want it to show up as a compilation error. Ideally, as class not found, but any error would do. I know I can manually configure the classpath when running outside of eclipse, and even within eclipse I can modify the classpath for a specific class I'm running (in the run configurations), but thats not manageable if you run alot of individual test cases, or have alot of main() classes.

• Extract attributes from NSManagedObject array.

  - by Pavel Peroutka

  NSFetchRequest *req = [NSFetchRequest init]; NSEntityDescription *descr = [NSEntityDescription entityForName:@"City" inManagedObjectContext:context]; [req setEntity:descr]; NSSortDescriptor *sort = [[NSSortDescriptor alloc] initWithKey:@"streetName" ascending:YES]; [req setSortDescriptors:[NSArray arrayWithObject:sort]]; [sort release]; //fetch NSError *error; NSArray *result = [context executeFetchRequest:req error:&error]; //extract names NSMutableArray *streets = [[NSMutableArray alloc] init]; for () { ??? = [array objectAtIndex:i]; [streets addObject:name]; } I expected Core Data to be little more intuitive. I am new in it and I could use some help. I fetched all objects(rows) from the entity (table) City. Now I have an array of objects. From the array I need to extract the attribute “streetName” to an array which will feed the picker. I figured I need to do it in the loop but I could not figure out the way to do it. Please help. I have a background with SQL but Core Data is still a big mystery to me. Is there any publication which would take a SQL statement and show comparable Core Data syntax? Thanks.

• git clone fails with "index-pack" failed?

  - by gct

  So I created a remote repo that's not bare (because I need redmine to be able to read it), and it's set to be shared with the group (so git init --shared=group). I was able to push to the remote repo and now I'm trying to clone it. If I clone it over the net I get this: remote: Counting objects: 4648, done. remote: Compressing objects: 100% (2837/2837), done. error: git-upload-pack: git-pack-objects died with error.B/s fatal: git-upload-pack: aborting due to possible repository corruption on the remote side. remote: aborting due to possible repository corruption on the remote side. fatal: early EOF fatal: index-pack failed I'm able to clone it locally without a problem, and I ran "git fsck", which only reports some dangling trees/blobs, which I understand aren't a problem. What could be causing this? I'm still able to pull from it, just not clone. I should note the remote git version is 1.5.6.5 while local is 1.6.0.4 I tried cloning my local copy of the repo, stripping out the .git folder and pushing to a new repo, then cloning the new repo and I get the same error, which leads me to believe it may be a file in the repo that's causing git-upload-pack to fail... Edit: I have a number of windows binaries in the repo, because I just built the python modules and then stuck them in there so everyone else didn't have to build them as well. If I remove the windows binaries and push to a new repo, I can clone again, perhaps that gives a clue. Trying to narrow down exactly what file is causing the problem now.

• Blackberry application works in simulator but not device

  - by Kai

  I read some of the similar posts on this site that deal with what seems to be the same issue and the responses didn't really seem to clarify things for me. My application works fine in the simulator. I believe I'm on Bold 9000 with OS 4.6. The app is signed. My app makes an HTTP call via 3G to fetch an XML result. type is application/xhtml+xml. In the device, it gives no error. it makes no visual sign of error. I tell the try catch to print the results to the screen and I get nothing. HttpConnection was taken right out of the demos and works fine in sim. Since it gives no error, I begin to reflect back on things I recall reading back when the project began. deviceside=true? Something like that? My request is simply HttpConnection connection = (HttpConnection)Connector.open(url); where url is just a standard url, no get vars. Based on the amount of time I see the connection arrows in the corner of the screen, I assume the app is launching the initial communication to my server, then either getting a bad result, or it gets results and the persistent store is not functioning as expected. I have no idea where to begin with this. Posting code would be ridiculous since it would be basically my whole app. I guess my question is if anyone knows of any major differences with device versus simulator that could cause something like http connection or persistent store to fail? A build setting? An OS restriction? Any standard procedure I may have just not known about that everyone should do before beginning device testing? Thanks

• How to test for existence of a script-scoped variable in PowerShell?

  - by Damian Powell

  Is it possible to test for the existence of a script-scoped variable in PowerShell? I've been using the PowerShell Community Extensions (PSCX) but I've noticed that if you import the module while Set-PSDebug -Strict is set, an error is produced: The variable '$SCRIPT:helpCache' cannot be retrieved because it has not been set. At C:\Users\...\Modules\Pscx\Modules\GetHelp\Pscx.GetHelp.psm1:5 char:24 While investigating how I might fix this, I found this piece of code in Pscx.GetHelp.psm1: #requires -version 2.0 param([string[]]$PreCacheList) if ((!$SCRIPT:helpCache) -or $RefreshCache) { $SCRIPT:helpCache = @{} } This is pretty straight forward code; if the cache doesn't exist or needs to be refreshed, create a new, empty cache. The problem is that calling $SCRIPT:helpCache while Set-PSDebug -Strict is in force casues the error because the variable hasn't been defined yet. Ideally, we could use a Test-Variable cmdlet but such a thing doesn't exist! I thought about looking in the variable: provider but I don't know how to determine the scope of a variable. So my question is: how can I test for the existence of a variable while Set-PSDebug -Strict is in force, without causing an error?

• Cannot implicity convert type void to System.Threading.Tasks.Task<bool>

  - by sagesky36

  I have a WCF Service that contains the following method. All the methods in the service are asynchrounous and compile just fine. public async Task<Boolean> ValidateRegistrationAsync(String strUserName) { try { using (YeagerTechEntities DbContext = new YeagerTechEntities()) { DbContext.Configuration.ProxyCreationEnabled = false; DbContext.Database.Connection.Open(); var reg = await DbContext.aspnet_Users.FirstOrDefaultAsync(f => f.UserName == strUserName); if (reg != null) return true; else return false; } } catch (Exception) { throw; } } My client application was set to access the WCF service with the check box for the "Allow generation of asynchronous operations" and it generated the proxy just fine. I am receiving the above subject error when trying to call this WCF service method from my client with the following code. Mind you, I know what the error message means, but this is my first time trying to call an asynchronous task in a WCF service from a client. Task<Boolean> blnMbrShip = db.ValidateRegistrationAsync(FormsAuthentication.Decrypt(cn.Value).Name); What do I need to do to properly call the method so the design time compile error disappears? Thanks so much in advance...

• Getting response status code 0 in SmartGWT webservice call using json

  - by Girish

  I have developed application using SmartGWT, now i need to call webservice using json to another application which is deployed in another server for submitting username and password. When i make a request with url and POST method, getting the response status code as 0 and response text as blank. Here is my code, public void sendRequest() throws Exception { // Get login json data to be sent to server. String strData = createLoginReqPacket(); String url = "some url"; RequestBuilder builder = new RequestBuilder(RequestBuilder.POST, url); builder.setHeader("Content-Type", "application/json"); builder.setHeader("Content-Length", strData.length() + ""); Request response = builder.sendRequest(strData, new RequestCallback() { @Override public void onResponseReceived(Request request, Response response) { int statusCode = response.getStatusCode(); System.out.println("Response code ----"+response.getStatusCode()+""); if (statusCode == Response.SC_OK) { String responseBody = response.getText(); System.out.println("Respose :" + responseBody); // do something with the response } else { GWT.log("Response error at server side ----",null); // do in case of server error } }// end of method. @Override public void onError(Request request, Throwable exception) { GWT.log("**** Error in service call ******",null); }// end of method. }); builder.send(); }// end of send request. Please anybody knows the solution?? Give some reference code or links for this. Thanks.

• why doesn't winmain set the errorlevel?

  - by Brian R. Bondy

  int APIENTRY _tWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPTSTR lpCmdLine, int nCmdShow) { MessageBox(NULL, _T("This should return 90 no?"), _T("OK"), MB_OK); return 90; } Why does the above program correctly display the message box, but does not set the error level? I compile this program to the name a.exe. Then from command prompt I type: c:\> a.exe (message box is displayed, I press ok) c:\> echo %ERRORLEVEL% 0 I get the same results if I do exit(90); right before the return. It still says 0. I also tried to start the program via CreateProcess and obtain the result with GetExitCodeProcess but it also returns 0 to me. I did error checking to ensure it was all started correctly. I originally seen this problem in a more complex program. But made this simple program to verify the problem. Results are the same, both programs that have WinMain return 0 always. I tried both x64, x86 and unicode and MBCS compiling options. All give 0 as an error level/status code.

• One or more rows contain values violating non-null, unique, or foreign-key constraints in SQL Script

  - by Musikero31

  Need help on this. I'm just wondering why this error occurred. Below is the script concerned. SELECT loc.ID ,loc.LocCode ,loc.LocName ,st.StateName ,reg.RegionName ,ctry.CountryName ,ISNULL(CONVERT(DATE, loc.UpdatedDate), CONVERT(DATE,loc.CreatedDate)) AS [ModifiedDate] ,stf.Name AS [ModifiedBy] FROM Spkr_Country AS ctry WITH (NOLOCK) INNER JOIN Spkr_Location AS loc WITH (NOLOCK) ON ctry.ID = loc.CountryID INNER JOIN Spkr_State AS st WITH (NOLOCK) ON loc.StateID = st.ID INNER JOIN Spkr_Region AS reg WITH (NOLOCK) ON loc.RegionID = reg.ID INNER JOIN Staff AS stf ON ISNULL(loc.UpdatedBy, loc.CreatedBy) = stf.StaffId WHERE (loc.IsActive = 1) AND ( (@LocCode = '') OR ( @LocCode <> '' AND loc.LocCode LIKE @LocCode + '%' ) ) AND ( (@RegionID < 1) OR ( @RegionID > 0 AND loc.RegionID = @RegionID ) ) AND ( (@StateID < 1) OR ( @StateID > 0 AND loc.StateID = @StateID ) ) AND ( (@CountryID < 1) OR ( @CountryID > 0 AND loc.CountryID = @CountryID ) ) The error probably occurred here INNER JOIN Staff AS stf ON ISNULL(loc.UpdatedBy, loc.CreatedBy) = stf.StaffId The requirement that I wanted is that if the loc.UpdatedBy is null, it will use the loc.CreatedBy column. However, when I used this, it generated the error mentioned. In the database, the loc.CreatedBy is not null while the loc.UpdatedBy is nullable. I checked it by running the script but it's working fine. How do I do with it? What's wrong with my code? Please help.

• Potential g++ template bug?

  - by Evan Teran

  I've encountered some code which I think should compile, but doesn't. So I'm hoping some of the local standards experts here at SO can help :-). I basically have some code which resembles this: #include <iostream> template <class T = int> class A { public: class U { }; public: U f() const { return U(); } }; // test either the work around or the code I want... #ifndef USE_FIX template <class T> bool operator==(const typename A<T>::U &x, int y) { return true; } #else typedef A<int> AI; bool operator==(const AI::U &x, int y) { return true; } #endif int main() { A<int> a; std::cout << (a.f() == 1) << std::endl; } So, to describe what is going on here. I have a class template (A) which has an internal class (U) and at least one member function which can return an instance of that internal class (f()). Then I am attempting to create an operator== function which compares this internal type to some other type (in this case an int, but it doesn't seem to matter). When USE_FIX is not defined I get the following error: test.cc: In function 'int main()': test.cc:27:25: error: no match for 'operator==' in 'a.A<T>::f [with T = int]() == 1' Which seems odd, because I am clearly (I think) defining a templated operator== which should cover this, in fact if I just do a little of the work for the compiler (enable USE_FIX), then I no longer get an error. Unfortunately, the "fix" doesn't work generically, only for a specific instantiation of the template. Is this supposed to work as I expected? Or is this simply not allowed? BTW: if it matters I am using gcc 4.5.2.

• jQuery Validation: Validating Checkboxes with Different Names

  - by Michael

  I have a set of 4 checkboxes, all with different names, and require that at least 1 is checked. I know there are a few posts on here already trying to answer this question. The solution that seems to be most logical to me is the answer posted on Question 1734840, but I can't seem to get it working! What's wrong with my code? Or any other new coding ideas to get this working? I have set the class on all of them to 'require-one'. My jQuery code is $(document).ready(function(){ $("#itemForm").validate({ highlight: function(element, errorClass, validClass) { $(element).addClass(errorClass).removeClass(validClass); $(element.form).find("label[for=" + element.name + "]") .addClass("radioerror"); }, unhighlight: function(element, errorClass, validClass) { $(element).removeClass(errorClass).addClass(validClass); $(element.form).find("label[for=" + element.name + "]") .removeClass("radioerror"); }, rules: { 'require-one': { required : { depends: function(element) { var allBoxes = $('.require-one'); if (allBoxes.filter(':checked').length == 0) { if (allBoxes.eq(element).length != 0) { return true; } } return false; } } } , }, errorPlacement: function(error, element) { if ( element.is("#other_descrip") ) error.appendTo("#othererror" ); if ( element.is("#itemlist") ) error.appendTo("#itemerror" ); } }); });
