• ASP.NET MVC hosting problem, routing, handlers and modules

  - by johnabs

  Hi, This is one of them again, hosting with fasthosts. I recently purchased a windows developer package from them. When I tried to deploy my ASP.NET 3.5 MVC project, which was working fine with the same host on a reseller account, it is not working. The reason to move from reseller to a normal Windows Developer package is, the MS-SQL server database is too expensive in a reseller account, strange! I contact them, and they are saying they upgraded the control panel. The technical support said, I need to disable the Modules and Handlers from the web.config file. Also I need to deploy them as .dll files. I am not sure how to do that. The website is partially working now. I think the problem is now with the routing. I have not deployed any .dlls apart from the System.Web.Mvc.dll, System.Web.Routing.dll and System.Web.Abstractions.dll. I have not got a clue on how to deploy the Modules and Handlers. The code that I commented on the web.config file is as follows. <!--<modules runAllManagedModulesForAllRequests="true"> <remove name="ScriptModule" /> <remove name="UrlRoutingModule" /> <add name="ScriptModule" preCondition="managedHandler" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/> <add name="UrlRoutingModule" type="System.Web.Routing.UrlRoutingModule, System.Web.Routing, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> </modules> <handlers> <remove name="WebServiceHandlerFactory-Integrated"/> <remove name="ScriptHandlerFactory" /> <remove name="ScriptHandlerFactoryAppServices" /> <remove name="ScriptResource" /> <remove name="MvcHttpHandler" /> <remove name="UrlRoutingHandler" /> <add name="ScriptHandlerFactory" verb="*" path="*.asmx" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/> <add name="ScriptHandlerFactoryAppServices" verb="*" path="*_AppService.axd" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/> <add name="ScriptResource" preCondition="integratedMode" verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <add name="MvcHttpHandler" preCondition="integratedMode" verb="*" path="*.mvc" type="System.Web.Mvc.MvcHttpHandler, System.Web.Mvc, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/> <add name="UrlRoutingHandler" preCondition="integratedMode" verb="*" path="UrlRouting.axd" type="System.Web.HttpForbiddenHandler, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" /> </handlers>--> Anybody got any ideas please. Thank you for your time.

• ie7 innerhtml strange display problem

  - by thoraniann

  Hello, I am having a strange problem with ie7 (ie8 in compatibility mode). I have div containers where I am updating values using javascript innhtml to update the values. This works fine in Firefox and ie8. In ie7 the values do not update but if a click on the values and highlight them then they update, also if a change the height of the browser then on the next update the values get updated correctly. I have figured out that if I change the position property of the outer div container from relative to static then the updates work correctly. The page can be viewed here http://islendingasogur.net/test/webmap_html_test.html In internet explorer 8 with compatibility turned on you can see that the timestamp in the gray box only gets updated one time, after that you see no changes. The timestamp in the lower right corner gets updated every 10 seconds. But if you highlight the text in the gray box then the updated timestamp values appears! Here is the page: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html;

• Problem with JSON, Struts 2 and Ajax.

  - by Javi

  Hello, I have an apllication with Struts 2, Spring and I want to send JSON as a response to an Ajax request, but my server in not sending the JSON in the response. I have this base package: <package name="myApp-default" extends="struts-default"> <result-types> <result-type name="tiles" class="org.apache.struts2.views.tiles.TilesResult" /> <result-type name="json" class="com.googlecode.jsonplugin.JSONResult"> <param name="enableGZIP">true</param> <param name="noCache">true</param> <param name="defaultEncoding">ISO-8859-1</param> </result-type> </result-types> </package> And another package which extends the previous one. <package namespace="/rest" name="rest" extends="myApp-default"> <action name="login" class="restAction" method="login"> <result type="json"/> </action> So I call with jQuery Ajax and debugging it I see it enters in the Action restAction in the method login and it also enters in the method getJsonData() because I have set two breakpoints and the program is stopped first in login and then in getJsonData. public class RestAction extends BaseAction { private String login; private String password; private String jsonData; public String login() { jsonData = "changed"; return Action.SUCCESS; } //I ommit getter/setters for login and password @JSON(name="jsonData") public String getJsonData() { return jsonData; } public void setJsonData(String jsonData) { this.jsonData = jsonData; } } My ajax looks like this: $.ajax({type: 'GET', url: this_url, data: pars, cache:false, success: handleResponse, error: handleError}); With firebug I see that the response to my request is completely void (though I have seen that the data saved in pars variable has been populated to the action and the methods have been executed correctly). And maybe for that reason my ajax enters in my handleError function where xmlHttpRequest.readyState is 4 and xmlHttpRequest.status is 0. Can anyone tell me what may the problem be? Thanks.

• log4net logging problem

  - by Dotnet_user

  Hello everyone, I'm not sure if this is the right forum to post this question. But I'm just hoping someone here might have used log4net in the past, so hoping to get some help. I'm using log4net to log my exceptions. The configuration settings look like this: <?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/> </configSections> <log4net debug="false"> <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender"> <file value="C:\Logs\sample.log" /> <appendToFile value="true"/> <rollingStyle value="Size"/> <maxSizeRollBackups value="10"/> <maximumFileSize value="10MB"/> <staticLogFileName value="true"/> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%-5level %date %logger.%method[line %line] - %message%newline"/> </layout> </appender> <root> <level value="INFO"/> <appender-ref ref="RollingLogFileAppender"/> </root> </log4net> </configuration> I started out by adding this configuration to web.config, but I got an error (VS studio could not find a schema for log4net-"Could not find schema information for the element log4net"). So I followed this link (http://stackoverflow.com/questions/174430/log4net-could-not-find-schema-information-messages) and configured my settings in a separate xml file and added the following line of code in my AssemblyInfo.cs: [assembly: log4net.Config.XmlConfigurator(ConfigFile = "xmlfile.xml", Watch = true)] And in the actual code, I placed this line: public void CreateUser(String username, String password) { try { log.Info("Inside createuser"); //code for creating user } catch(exception e) { log.Info("something happened in create user", e); } } The problem is that the log file is not being created. I can't see anything inside C:\Logs. Can anybody tell me what I'm doing wrong here? Any suggestions/inputs will be very helpful. Thank you all in advance.

• PHP & MySQL - Deleting table rows problem.

  - by oReiLLy

  Okay my script is supposed to delete a specific users case which is stored in 2 MySQL tables but for some reason when the user deletes the specific case it deletes all the users cases I only want it to delete the case the user selects. I was wondering how can I fix this problem? Thanks in advance for helping.

• problem with reload data from table view after come back from another view

  - by user129677

  I have a problem in my application. Any help will be greatly appreciated. Basically it is from view A to view B, and then come back from view B. In the view A, it has dynamic data loaded in from the database, and display on the table view. In this page, it also has the edit button, not on the navigation bar. When user tabs the edit button, it goes to the view B, which shows the pick view. And user can make any changes in here. Once that is done, user tabs the back button on the navigation bar, it saves the changes into the NSUserDefaults, goes back to the view A by pop the view B. When coming back to the view A, it should get the new data from the UIUserDefaults, and it did. I user NSLog to print out to the console and it shows the correct data. Also it should invoke the viewWillAppear: method to get the new data for the table view, but it didn't. It even did not call the tableView:numberOfRowsInSection: method. I place a NSLog statement inside this method but didn't print out in the console. as the result, the view A still has the old data. the only way to get the new data in the view A is to stop and start the application. both view A and view B are the subclass of UIViewController, with UITableViewDelegate and UITableViewDataSource. here is my code in the view A : - (void)viewWillAppear:(BOOL)animated { NSLog(@"enter in Schedule2ViewController ..."); // load in data from database, and store into NSArray object //[self.theTableView reloadData]; [self.theTableView setNeedsDisplay]; //[self.theTableView setNeedsLayout]; } in here, the "theTableView" is a UITableView variable. And I try all three cases of "reloadData", "setNeedsDisplay", and "setNeedsLayout", but didn't seem to work. in the view B, here is the method corresponding to the back button on the navigation bar. - (void)viewDidLoad { UIBarButtonItem *saveButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemSave target:self action:@selector(savePreference)]; self.navigationItem.leftBarButtonItem = saveButton; [saveButton release]; } - (IBAction) savePreference { NSLog(@"save preference."); // save data into the NSUSerDefaults [self.navigationController popViewControllerAnimated:YES]; } Am I doing in the right way? Or is there anything that I missed? Many thanks.

• Google Maps Rollover Problem in a Flex Website

  - by Laxmidi

  Hi, I'm using Google Maps in my Flex site to create a map. I've got polygons overlayed on the map. When the user rolls over a polygon an infowindow opens identifying the area and the fill Alpha of the area is set to 0. On roll-out, the info window is removed and the fill Alpha is returned to the default, 0.2. The polygons display and the InfoWindow is added and removed correctly. The problem is that the change in fill alpha only occurs on the very last polygon in the list. So for example, if I have polygons A, B, C, and D. If I rollover A, then A's alpha should change. But, instead D's alpha changes. No matter which polygon I rollover, the last polygon's alpha changes. It's weird, because the infoWindows behave correctly on rollover. So, if I rollover polygon A, the correct information for InfoWindow A appears. Please see the code below: private function allEncodedPolygons(event:MouseEvent) : void { var myPaneManager:IPaneManager = map.getPaneManager(); var myMapPane:IPane = myPaneManager.createPane(); if (allHoodsToggle.selected) { map.clearOverlays(); mapType.selectedIndex = -1; for each (var neighbNode:XML in detailMapResultData){ outlinePolygon = this.createPoly(neighbNode); map.addOverlay(outlinePolygon)}; allHoodsToggle.removeEventListener(MouseEvent.CLICK, allEncodedPolygons); } else {myPaneManager.clearOverlays(); allHoodsToggle.removeEventListener(MouseEvent.CLICK, allEncodedPolygons); } } The function below creates the polygons and has the rollover function: private var neighbShapes:Polygon; private function createPoly(neighbNode:XML):Polygon { var optionsDefault:PolygonOptions = new PolygonOptions( { strokeStyle: {thickness: 5, color: 0xFFFF00, alpha: 0.4, pixelHinting: true}, fillStyle: { alpha: 0.2 }} ); var neighbCenterLat:Number = neighbNode.latitudeCenter.toString(); var neighbCenterLong:Number = neighbNode.longitudeCenter.toString(); var neighbCenter:LatLng = new LatLng(neighbCenterLat,neighbCenterLong); var optionsHover:PolygonOptions = new PolygonOptions( { fillStyle: { alpha: 0.0 }} ); var encodedData:EncodedPolylineData = new EncodedPolylineData(neighbNode.encoding.toString(), neighbNode.zoomFactor.toString(), neighbNode.level.toString(), neighbNode.numlevels.toString()); var encodedList:Array = [encodedData]; neighbShapes = Polygon.fromEncoded(encodedList, optionsDefault); neighbShapes.addEventListener(MapMouseEvent.CLICK, function(event:MapMouseEvent): void { map.openInfoWindow(event.latLng, new InfoWindowOptions({content: neighbNode.name.toString(), hasCloseButton:false, hasShadow:true})); }); neighbShapes.addEventListener(MapMouseEvent.ROLL_OVER, function(event:MapMouseEvent): void { neighbShapes.setOptions(optionsHover); map.openInfoWindow(neighbCenter, new InfoWindowOptions({content: neighbNode.name.toString(), hasCloseButton:false, hasShadow:false})); }); neighbShapes.addEventListener(MapMouseEvent.ROLL_OUT, function(event:MapMouseEvent): void { neighbShapes.setOptions(optionsDefault); }); return neighbShapes; } Any suggestions as to why the function that changes the alpha is firing on the last polygon only, even though the InfoWindow appears correctly? If anyone has any ideas, I'd love to hear them. Thanks. -Laxmidi

• stringstream problem - vector iterator not dereferencable

  - by andreas

  Hello I've got a problem with the following code snippet. It is related to the stringstream "stringstream css(cv.back())" bit. If it is commented out the program will run ok. It is really weird, as I keep getting it in some of my programs, but if I just create a console project the code will run fine. In some of my Win32 programs it will and in some it won't (then it will return "vector iterator not dereferencable" but it will compile just fine). Any ideas at all would be really appreciated. Thanks! vector<double> cRes(2); vector<double> pRes(2); int readTimeVects2(vector<double> &cRes, vector<double> &pRes){ string segments; vector<string> cv, pv, chv, phv; ifstream cin("cm.txt"); ifstream pin("pw.txt"); ifstream chin("hm.txt"); ifstream phin("hw.txt"); while (getline(cin,segments,'\t')) { cv.push_back(segments); } while (getline(pin,segments,'\t')) { pv.push_back(segments); } while (getline(chin,segments,'\t')) { chv.push_back(segments); } while (getline(phin,segments,'\t')) { phv.push_back(segments); } cin.close(); pin.close(); chin.close(); phin.close(); stringstream phss(phv.front()); phss >> pRes[0]; phss.clear(); stringstream chss(chv.front()); chss >> cRes[0]; chss.clear(); stringstream pss(pv.back()); pss >> pRes[1]; pss.clear(); stringstream css(cv.back()); css >> cRes[1]; css.clear(); return 0; }

• Help with a logic problem

  - by Stradigos

  I'm having a great deal of difficulty trying to figure out the logic behind this problem. I have developed everything else, but I really could use some help, any sort of help, on the part I'm stuck on. Back story: *A group of actors waits in a circle. They "count off" by various amounts. The last few to audition are thought to have the best chance of getting the parts and becoming stars. Instead of actors having names, they are identified by numbers. The "Audition Order" in the table tells, reading left-to-right, the "names" of the actors who will be auditioned in the order they will perform.* Sample output: etc, all the way up to 10. What I have so far: using System; using System.Collections; using System.Text; namespace The_Last_Survivor { class Program { static void Main(string[] args) { //Declare Variables int NumOfActors = 0; System.DateTime dt = System.DateTime.Now; int interval = 3; ArrayList Ring = new ArrayList(10); //Header Console.Out.WriteLine("Actors\tNumber\tOrder"); //Add Actors for (int x = 1; x < 11; x++) { NumOfActors++; Ring.Insert((x - 1), new Actor(x)); foreach (Actor i in Ring) { Console.Out.WriteLine("{0}\t{1}\t{2}", NumOfActors, i, i.Order(interval, x)); } Console.Out.WriteLine("\n"); } Console.In.Read(); } public class Actor { //Variables protected int Number; //Constructor public Actor(int num) { Number = num; } //Order in circle public string Order(int inter, int num) { //Variable string result = ""; ArrayList myArray = new ArrayList(num); //Filling Array for (int i = 0; i < num; i++) myArray.Add(i + 1); //Formula foreach (int element in myArray) { if (element == inter) { result += String.Format(" {0}", element); myArray.RemoveAt(element); } } return result; } //String override public override string ToString() { return String.Format("{0}", Number); } } } } The part I'm stuck on is getting some math going that does this: Can anyone offer some guidance and/or sample code?

• Flex - Problem with auto resizing datagrid

  - by Marty Pitt

  Hi All I'm trying to create a datagrid which will resize vertically to ensure all the renderers are displayed in full. Additionally, Renderers are of variable height Renderers can resize themselves Generally speaking, the flow of events is as follows : One of the item renderers resizes itself (normally in response to a user click etc) It dispatches a bubbling event which the parent datagrid picks up The DataGrid attempts to resize to ensure that all renderers remain visible in full. I'm currently using this code within the datagrid to calculate the height: height = measureHeightOfItems(0, dataProvider.length ) + headerHeight; This appears to get an incorrect height. I've tried a number of variations including callLater ( to ensure the resize has completed so measure can work correctly), and overriding meausre() and calling invalidateSize() / validateSize(), but neither works. Below are 3 classes which will illustrate the problem. Clicking the button in the item renderers resizes the renderer. The grid should also expand so that all of the 3 renderers are shown in their entirety. Any suggestions would be greatly appreciated.

  Hi! I have a code that need to be "translated" from C to Cpp, and i cant understand, where's a problem. There is the part, where it crashes (windows critical error send/dontSend): nDim = sizeMax*(sizeMax+1)/2; printf("nDim = %d sizeMax = %d\n",nDim,sizeMax); hamilt = (double*)malloc(nDim*sizeof(double)); printf("End hamilt alloc. %d allocated\n",(nDim*sizeof(double))); transProb = (double*)malloc(sizeMax*sizeMax*sizeof(double)); printf("End transProb alloc. %d allocated\n",(sizeMax*sizeMax*sizeof(double))); eValues = (double*)malloc(sizeMax*sizeof(double)); printf("eValues allocated. %d allocated\n",(sizeMax*sizeof(double))); eVectors = (double**)malloc(sizeMax*sizeof(double*)); printf("eVectors allocated. %d allocated\n",(sizeMax*sizeof(double*))); if(eVectors) for(i=0;i<sizeMax;i++) { eVectors[i] = (double*)malloc(sizeMax*sizeof(double)); printf("eVectors %d-th element allocated. %d allocated\n",i,(sizeMax*sizeof(double))); } eValuesPrev = (double*)malloc(sizeMax*sizeof(double)); printf("eValuesPrev allocated. %d allocated\n",(sizeMax*sizeof(double))); eVectorsPrev = (double**)malloc(sizeMax*sizeof(double*)); printf("eVectorsPrev allocated. %d allocated\n",(sizeMax*sizeof(double*))); if(eVectorsPrev) for(i=0;i<sizeMax;i++) { eVectorsPrev[i] = (double*)malloc(sizeMax*sizeof(double)); printf("eVectorsPrev %d-th element allocated. %d allocated\n",i,(sizeMax*sizeof(double))); } Log: nDim = 2485 sizeMax = 70 End hamilt alloc. 19880 allocated End transProb alloc. 39200 allocated eValues allocated. 560 allocated eVectors allocated. 280 allocated So it crashes at the start of the loop of allocation. If i delete this loop it crashes at the next line of allocation. Does it mean that with the numbers like this i have not enough memory?? Thank you.

• FASM vc MASM trasnlation problem in mov si, offset msg

  - by Ruben Trancoso

  hi folks, just did my first test with MASM and FASM with the same code (almos) and I falled in trouble. The only difference is that to produce just the 104 bytes I need to write to MBR in FASM I put org 7c00h and in MASM 0h. The problem is on the mov si, offset msg that in the first case transletes it to 44 7C (7c44h) and with masm translates to 44 00 (0044h)! but just when I change org 7c00h to org 0h in MASM. Otherwise it will produce the entire segment from 0 to 7dff. how do I solve it? or in short, how to make MASM produce a binary that begins at 7c00h as it first byte and subsequent jumps remain relative to 7c00h? .model TINY .code org 7c00h ; Boot entry point.

  I am having a bit of trouble. It does not seem to be a big deal, but I have created a page that the user can edit a MySQL database.

• Two way binding settings problem.

  - by Jamie

  Hi, I am having a problem using two way binding with a listpicker. I am able to set the value using c# but not in the SelectedItem=".." in xaml. The binding is returning the correct value (and is a value in the listpicker) as i have texted it by assigning the text to a textblock. When the page loads, the binding used on the listpicker causes a System.ArgumentOutOfRangeException The code i am using to set it is: // Update a setting value. If the setting does not exist, add the setting. public bool AddOrUpdateValue(string key, Object value) { bool valueChanged = false; try { // If new value is different, set the new value if (settingsStorage[key] != value) { settingsStorage[key] = value; valueChanged = true; } } catch (KeyNotFoundException) { settingsStorage.Add(key, value); valueChanged = true; } catch (ArgumentException) { settingsStorage.Add(key, value); valueChanged = true; } catch (Exception e) { Console.WriteLine("Exception occured whilst using IsolatedStorageSettings: " + e.ToString()); } return valueChanged; } // Get the current value of the setting, if not found, set the setting to default value. public valueType GetValueOrDefault<valueType>(string key, valueType defaultValue) { valueType value; try { value = (valueType)settingsStorage[key]; } catch (KeyNotFoundException) { value = defaultValue; } catch (ArgumentException) { value = defaultValue; } return value; } public string WeekBeginsSetting { get { return GetValueOrDefault<string>(WeekBeginsSettingKeyName, WeekBeginsSettingDefault); } set { AddOrUpdateValue(WeekBeginsSettingKeyName, value); Save(); } } And in the xaml: <toolkit:ListPicker x:Name="WeekStartDay" Header="Week begins on" SelectedItem="{Binding Source={StaticResource AppSettings}, Path=WeekBeginsSetting, Mode=TwoWay}"> <sys:String>monday</sys:String> <sys:String>sunday</sys:String> </toolkit:ListPicker> The StaticResource AppSettings is a resource from a seperate .cs file. <phone:PhoneApplicationPage.Resources> <local:ApplicationSettings x:Key="AppSettings"></local:ApplicationSettings> </phone:PhoneApplicationPage.Resources> Thanks in advance

• Problem with jQuery.ajax with 'delete' method in ie

  - by Max Williams

  I have a page where the user can edit various content using buttons and selects that trigger ajax calls. In particular, one action causes a url to be called remotely, with some data and a 'put' request, which (as i'm using a restful rails backend) triggers my update action. I also have a delete button which calls the same url but with a 'delete' request. The 'update' ajax call works in all browsers but the 'delete' one doesn't work in IE. I've got a vague memory of encountering something like this before...can anyone shed any light? here's my ajax calls: //update action - works in all browsers jQuery.ajax({ async:true, data:data, dataType:'script', type:'put', url:"/quizzes/"+quizId+"/quiz_questions/"+quizQuestionId, success: function(msg){ initializeQuizQuestions(); setPublishButtonStatus(); } }); //delete action - fails in ie function deleteQuizQuestion(quizQuestionId, quizId){ //send ajax call to back end to change the difficulty of the quiz question //back end will then refresh the relevant parts of the page (progress bars, flashes, quiz status) jQuery.ajax({ async:true, dataType:'script', type:'delete', url:"/quizzes/"+quizId+"/quiz_questions/"+quizQuestionId, success: function(msg){ alert("success"); initializeQuizQuestions(); setSelectStatus(quizQuestionId, true); jQuery("tr[id*='quiz_question_"+quizQuestionId+"']").removeClass('selected'); }, error: function(msg){ alert("error:" + msg); } }); } I put the alerts in success and error in the delete ajax just to see what happens, and the 'error' part of the ajax call is triggered, but WITH NO CALL BEING MADE TO THE BACK END (i know this by watching my back end server logs). So, it fails before it even makes the call. I can't work out why - the 'msg' i get back from the error block is blank. Any ideas anyone? Is this a known problem? I've tested it in ie6 and ie8 and it doesn't work in either. thanks - max EDIT - the solution - thanks to Nick Craver for pointing me in the right direction. Rails (and maybe other frameworks?) has a subterfuge for the unsupported put and delete requests: a post request with the parameter "_method" (note the underscore) set to 'put' or 'delete' will be treated as if the actual request type was that string. So, in my case, i made this change - note the 'data' option': jQuery.ajax({ async:true, data: {"_method":"delete"}, dataType:'script', type:'post', url:"/quizzes/"+quizId+"/quiz_questions/"+quizQuestionId, success: function(msg){ alert("success"); initializeQuizQuestions(); setSelectStatus(quizQuestionId, true); jQuery("tr[id*='quiz_question_"+quizQuestionId+"']").removeClass('selected'); }, error: function(msg){ alert("error:" + msg); } }); } Rails will now treat this as if it were a delete request, preserving the REST system. The reason my PUT example worked was just because in this particular case IE was happy to send a PUT request, but it officially does not support them so it's best to do this for PUT requests as well as DELETE requests.

This is my code. public void CheckSpelling() { try { // declare local variables to track error count // and information int SpellingErrors = 0; string ErrorCountMessage = string.Empty; // create an instance of a word application Microsoft.Office.Interop.Word.Application WordApp = new Microsoft.Office.Interop.Word.Application(); // hide the MS Word document during the spellcheck //WordApp.WindowState = WdWindowState.wdWindowStateMinimize; // check for zero length content in text area if (this.Text.Length > 0) { WordApp.Visible = false; // create an instance of a word document _Document WordDoc = WordApp.Documents.Add(ref emptyItem, ref emptyItem, ref emptyItem, ref oFalse); // load the content written into the word doc WordDoc.Words.First.InsertBefore(this.Text); // collect errors form new temporary document set to contain // the content of this control Microsoft.Office.Interop.Word.ProofreadingErrors docErrors = WordDoc.SpellingErrors; SpellingErrors = docErrors.Count; // execute spell check; assumes no custom dictionaries WordDoc.CheckSpelling(ref oNothing, ref oIgnoreUpperCase, ref oAlwaysSuggest, ref oNothing, ref oNothing, ref oNothing, ref oNothing, ref oNothing, ref oNothing, ref oNothing, ref oNothing, ref oNothing); // format a string to contain a report of the errors detected ErrorCountMessage = "Spell check complete; errors detected: " + SpellingErrors; // return corrected text to control's text area object first = 0; object last = WordDoc.Characters.Count - 1; this.Text = WordDoc.Range(ref first, ref last).Text; } else { // if nothing was typed into the control, abort and inform user ErrorCountMessage = "Unable to spell check an empty text box."; } WordApp.Quit(ref oFalse, ref emptyItem, ref emptyItem); System.Runtime.InteropServices.Marshal.ReleaseComObject(WordApp); // return report on errors corrected // - could either display from the control or change this to // - return a string which the caller could use as desired. // MessageBox.Show(ErrorCountMessage, "Finished Spelling Check"); } catch (Exception e) { MessageBox.Show(e.ToString()); } } The spell checker works well, the only problem is when I try to move the spell checker the main form blurs up for some reason. Also when I close the spell checker the main form is back to normal. It seems like it is opening up Microsoft word then hiding the window, only allowing the spell checker to be seen. Please help.

• Block element text overflow problem in IE7

  - by Adomas

  I'm making a "sort elements" web game using jQuery, HTML & CSS. While everything works fine in FF, IE8, Opera, Chrome, I'm having problem with IE7 wrapping words inside block elements. Here's how it looks in IE7 (wrong): Link (cannot post images as a new user) In IE8 the box with wrapped text would just expand to fit it whole in one line without any overflows. Sorry, can't give another link as a new user Don't mind the element order as it's random. Elements are dynamically generated by jQuery. HTML code: <div class="ui-sortable" id="area"> <span class="object">: </span> <span class="object">1998- </span> <span class="object">ISSN 1392-4087</span> <span class="object">, </span> <span class="object">. </span> <span class="object">nepriklausomas savaitraštis buhalteriams, finansininkams, auditoriams</span> <span class="object">. </span> <span class="object">. </span> <span class="object">. </span> <span class="object">Vilnius</span> <span class="object">1998- </span> <span class="object"><em>Apskaitos, audito ir mokesciu aktualijos</em></span> </div> CSS code (irrelevant info like fonts & colors removed): #area { min-height: 160px; width: 760px; } .object { display: block; float: left; text-align: center; width: auto; } Any comments on why does IE7 does that? How do I make these spans expand to fit the whole text in one line in IE7 and not wrap the text or make overflows?

• Query an XmlDocument without getting a 'Namespace prefix is not defined' problem

  - by Dan Revell

  I've got an Xml document that both defines and references some namespaces. I load it into an XmlDocument object and to the best of my knowledge I create a XmlNamespaceManager object with which to query Xpath against. Problem is I'm getting XPath exceptions that the namespace "my" is not defined. How do I get the namespace manager to see that the namespaces I am referencing are already defined. Or rather how do I get the namespace definitions from the document to the namespace manager. Furthermore tt strikes me as strange that you have to provide a namespace manager to the document which you create from the documents nametable in the first place. Even if you need to hardcode manual namespaces why can't you add them directly to the document. Why do you always have to pass this namespace manager with every single query? What can't XmlDocument just know? The Code: XmlDocument xmlDoc = new XmlDocument(); xmlDoc.Load(programFiles + @"Common Files\Microsoft Shared\web server extensions\12\TEMPLATE\FEATURES\HfscBookingWorkflow\template.xml"); XmlNamespaceManager ns = new XmlNamespaceManager(xmlDoc.NameTable); XmlNode referenceNode = xmlDoc.SelectSingleNode("/my:myFields/my:ReferenceNumber", ns); referenceNode.InnerXml = this.bookingData.ReferenceNumber; XmlNode titleNode = xmlDoc.SelectSingleNode("/my:myFields/my:Title", ns); titleNode.InnerXml = this.bookingData.FamilyName; ... The Xml: <?xml version="1.0" encoding="UTF-8" ?> <?mso-infoPathSolution name="urn:schemas-microsoft-com:office:infopath:Inspection:-myXSD-2010-01-15T18-21-55" solutionVersion="1.0.0.104" productVersion="12.0.0" PIVersion="1.0.0.0" ?> <?mso-application progid="InfoPath.Document" versionProgid="InfoPath.Document.2"?> - <my:myFields xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xhtml="http://www.w3.org/1999/xhtml" xmlns:my="http://schemas.microsoft.com/office/infopath/2003/myXSD/2010-01-15T18:21:55" xmlns:xd="http://schemas.microsoft.com/office/infopath/2003"> <my:DateRequested xsi:nil="true" /> <my:DateVisited xsi:nil="true" /> <my:ReferenceNumber /> <my:FireCall>false</my:FireCall> ...

• ActionListener problem

  - by thegamer

  Hello, i am trying to make an actionListener on a button in another button which has also an actionlistener and i just couldn't figure it out for some way. I am trying to make an action on the 2nd button but i couldn't figure it out.If anyone helps me i'd appreciate! here is the code below: import java.awt.; import java.awt.event.; import javax.swing.; import java.io.; import java.util.*; public class basic implements ActionListener{ public static void main(String[] args) { basic process = new basic (); } public basic(){ JFrame fan = new JFrame("Scheme"); JPanel one = new JPanel(new BorderLayout()); fan.add(one); JPanel uno = new JPanel(); uno.setLayout(new BoxLayout(uno, BoxLayout.Y_AXIS)); JButton addB = new JButton("first choice"); addB.setAlignmentX(Component.CENTER_ALIGNMENT); uno.add(addB); addDButton.setActionCommand("hehe"); addDButton.addActionListener(this); one.add(uno,BorderLayout.CENTER); fan.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); fan.setSize(500,700); fan.setLocationByPlatform(true); fan.setVisible(true); } public void actionPerformed(ActionEvent evt) { JPanel markP = new JPanel(new FlowLayout(FlowLayout.RIGHT,10,20)); JDialog dialog = new JDialog((JFrame)null); dialog.getContentPane().add(markP,BorderLayout.CENTER); if (evt.getActionCommand().equals("hehe")) { JLabel title = new JLabel("Proceed"); title.setFont(new Font("Arial",Font.BOLD,15)); markP.add(title,BorderLayout.NORTH); JButton exit = new JButton("Exit"); markP.add(exit); //here i want to create another actionListener on the exit button only without affecting the other content which is in the button "addB " so that when i click on the addB button the J dialog pops up, and than when i click on exit button the program will return to the menu.I couldn't figure it out. dialog.toFront(); dialog.setModal(true); dialog.pack(); // dialog.setLocationRelativeTo(null); // dialog.setVisible(true); } // here the code goes on but the problem is that of the actionListener which is concerned.
