  • Difference in clientX and clientY when going out of the browser on ie/ff

    - by Py
    I just ran into a little problem with clientX and clientY. I put a little event to detect if the mouse goes out of the window and to know where it exits. And there come the trouble, it works fine with firefox, but only sends -1 as an answer in IE. Does someone know if there is a way to solve easily that problem and that without using a framework? A little bit of code to reproduce that: <html> <head> <script type="text/javascript"> document.onmouseout=function(e){ if (!e) var e = window.event; var relTarg = e.relatedTarget || e.toElement; if (!relTarg){ document.getElementById('result1').innerHTML="e.clientY:"+e.clientY+" e.clientX:"+e.clientX; } }; </script> </head> <body> <div id="result1">Not Yet</div> </body> </html> the results if I exit through the left of the window are: e.clientY:302 e.clientX:-130 on firefox e.clientY:-1 e.clientX:-1 on ie. Thanks in advance.

  • A potentially dangerous Request.Form value was detected: Dealing with these errors proactively, or a

    - by Albert
    I'm noticing this error more and more in my error logs. I've read through the questions here talking about this error, but they don't address what I would like to do (see below). I'm considering three options, in the order of preference: 1) When submitting a form (I use formviews almost exclusively, if that helps), if potentially dangerous characters are detected, automatically strip them out and submit. 2) When submitting a form, if potentially dangerous characters are detected, alert the user and let them fix it before trying again. 3) After the exception is generated, deal with it and alert the user. I'm hoping one of the first two options might be able to do somewhat globally...I know for the 3rd I'd have to alter a TON of Try-Catch blocks I already have in place. Doable, but labor intensive. I'd rather be proactive about it if at all possible and avoid the exception all together. Perhaps one approach to #1 would be to write a block of code that could loop through all text entry fields in a formview, during the insert/update event, and strip the characters out. I'm ok with that, but I'd rather not have to heavily alter all my Insert/Update events to accomplish this. Or maybe I just create a different class to do the text checking/deleting, and only insert 1 line of code in each Insert/Update event. If anyone can come up with some example code of any of these approaches that would be a help. Thanks for any ideas or information. I'm definitely open to other solutions too; these are only the 3 that came to mind. I can say that I don't want to turn request validation off though.

  • Declaration, allocation and assignment of an array of pointers to function pointers

    - by manneorama
    Hello Stack Overflow! This is my first post, so please be gentle. I've been playing around with C from time to time in the past. Now I've gotten to the point where I've started a real project (a 2D graphics engine using SDL, but that's irrelevant for the question), to be able to say that I have some real C experience. Yesterday, while working on the event system, I ran into a problem which I couldn't solve. There's this typedef, //the void parameter is really an SDL_Event*. //but that is irrelevant for this question. typedef void (*event_callback)(void); which specifies the signature of a function to be called on engine events. I want to be able to support multiple event_callbacks, so an array of these callbacks would be an idea, but do not want to limit the amount of callbacks, so I need some sort of dynamic allocation. This is where the problem arose. My first attempt went like this: //initial size of callback vector static const int initial_vecsize = 32; //our event callback vector static event_callback* vec = 0; //size static unsigned int vecsize = 0; void register_event_callback(event_callback func) { if (!vec) __engine_allocate_vec(vec); vec[vecsize++] = func; //error here! } static void __engine_allocate_vec(engine_callback* vec) { vec = (engine_callback*) malloc(sizeof(engine_callback*) * initial_vecsize); } First of all, I have omitted some error checking as well as the code that reallocates the callback vector when the number of callbacks exceed the vector size. However, when I run this code, the program crashes as described in the code. I'm guessing segmentation fault but I can't be sure since no output is given. I'm also guessing that the error comes from a somewhat flawed understanding on how to declare and allocate an array of pointers to function pointers. Please Stack Overflow, guide me.

  • Programatically enable/disable menuBar buttons in Flex 4

    - by Hamid
    I have the following XML in my Flex4 (AIR) project that defines the start of my menu interface: <mx:MenuBar x="0" y="0" width="100%" id="myMenuBar" labelField="@label" itemClick="menuChange(event)"> <mx:dataProvider> <s:XMLListCollection> <fx:XMLList xmlns=""> <menu label="File"> <item label="New"/> <item label="Load"/> <item label="Save" enabled="false"/> </menu> <menu label="Help"> <item label="About"/> </menu> </fx:XMLList> </s:XMLListCollection> </mx:dataProvider> </mx:MenuBar> I am trying to find the syntax that will let me set the save button to enabled=true after a file has been loaded by clicking "Load", however I can't figure out the syntax, can someone make a suggestion please. Currently the way that button clicks are detected is by a Switch/Case testing the String result of the MenuEvent event.item.@label. Maybe this isn't the best way?

  • jboss cache as hibernate 2nd level - cluster node doesn't persist replicated data

    - by Sergey Grashchenko
    I'm trying to build an architecture basically described in user guide http://www.jboss.org/file-access/default/members/jbosscache/freezone/docs/3.2.1.GA/userguide_en/html/cache_loaders.html#d0e3090 (Replicated caches with each cache having its own store.) but having jboss cache configured as hibernate second level cache. I've read manual for several days and played with the settings but could not achieve the result - the data in memory (jboss cache) gets replicated across the hosts, but it's not persisted in the datasource/database of the target (not original) cluster host. I had a hope that a node might become persistent at eviction, so I've got a cache listener and attached it to @NoveEvicted event. I found that though I could adjust eviction policy to fully control it, no any persistence takes place. Then I had a though that I could try to modify CacheLoader to set "passivate" to true, but I found that in my case (hibernate 2nd level cache) I don't have a way to access a loader. I wonder if replicated data persistence is possible at all by configuration tuning ? If not, will it work for me to create some manual peristence in CacheListener (I could check whether the eviction event is local, and if not - persist it to hibernate datasource somehow) ? I've used mvcc-entity configuration with the modification of cacheMode - set to REPL_ASYNC. I've also played with the eviction policy configuration. Last thing to mention is that I've tested entty persistence and replication in project that has been generated with Seam. I guess it's not important though.

  • WinForms - DateTimePicker default month selection behavior for Server 2003 vs Server 2008?

    - by Mike Loux
    Good Afternoon! Has anybody else noticed a change in the default behavior of the "next" and "previous" month arrows in the standard WinForms DateTimePicker control? I have users running on both Windows Server 2003 and Windows Server 2008 R2, and they are reporting that on 2008 (and Vista/Win7), clicking the right or left arrows on the drop-down Calendar now selects the first day of the month rather than retaining the same day like 2003 (and XP) does. I have checked this out (I have a Win7 machine) and I have confirmed this behavior. I would prefer that the behavior remain consistent whenever possible. Does anybody know what causes this and if there is a way to get around this? Is there a way to trap the arrow-click event and force the resulting date to retain the original day rather than be reset to the first of the month? I thought about seeing if there was a way to hit-test the control on a MouseUp event and determine if the arrow buttons were clicked, and then override the month value being set, but I'm not sure if that is even possible. Can anybody provide some wisdom or insight? Thanks!

  • convert htmlelement to string for comparison javascript

    - by Jamex
    Hi, I am using a function that obtains a target element id at onclick. Example, if I click on the text element that has the id of 'help'. var click = (e && e.target) || (event && event.srcElement); The var click would contain the ref to the id of "help". I want to compare the var click to the string 'help' using the if statement below. if (click == 'about') {do something} The comparison does not work because the var click is not a string. When I use the alert(click) to debug, it shows click as "object HTMLElement". How would you compare whether the id 'help' is obtained from var click? I could write out something like if (click == document.getElementById('help')) {do something} but that would make a long statement. also if the var click is document.getElementById('help'), how would you make a new var "show" as document.getElementById('showhelp') basically, I want to use the same function to generate dynamic responses to each element that was clicked on, and not having to create a separate function for each element.

  • Qt cross thread call

    - by QLatvia
    I have a Qt/C++ application, with the usual GUI thread, and a network thread. The network thread is using an external library, which has its own select() based event loop... so the network thread isn't using Qt's event system. At the moment, the network thread just emit()s signals when various events occur, such as a successful connection. I think this works okay, as the signals/slots mechanism posts the signals correctly for the GUI thread. Now, I need for the network thread to be able to call the GUI thread to ask questions. For example, the network thread may require the GUI thread to request put up a dialog, to request a password. Does anyone know a suitable mechanism for doing this? My current best idea is to have the network thread wait using a QWaitCondition, after emitting an object (emit passwordRequestedEvent(passwordRequest);. The passwordRequest object would have a handle on the particular QWaitCondition, and so can signal it when a decision has been made.. Is this sort of thing sensible? or is there another option?

  • VB.NET: Dialog exits when enter pressed?

    - by Camilo Martin
    Hi all; My problem seems to be quite simple, but it's not working the intuitive way. I'm designing a Windows Forms Application, and there is a dialog that should NOT exit when the enter key is pressed, instead it has to validate data first, in case enter was pressed after changing the text of a ComboBox. I've tried by telling it what to do on KeyPress event of the ComboBox if e is the Enter key: Private Sub ComboBoxSizeChoose_KeyPress(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles ComboBoxSizeChoose.KeyPress If e.KeyChar = Convert.ToChar(Keys.Enter) Then Try TamanhoDaNovaFonte = Single.Parse(ComboBoxSizeChoose.Text) Catch ex As Exception Dim Dialogo2 As New Dialog2 Dialog2.ShowDialog() ComboBoxSizeChoose.Text = TamanhoDaNovaFonte End Try End If End Sub But no success so far. When the Enter key is pressed, even with the ComboBox on focus, the whole dialog is closed, returning to the previous form. The validation is NOT done at all, and it has to be done before exiting. In fact, I don't even want to exit on the form's enter KeyPress, the only purpose of the enter key on the whole dialog is to validate the ComboBox (but only when in focus, for the sake of an intuitive UI). I've also tried appending the validation to the KeyPress event of the whole dialog's form, if the key is Enter. NO SUCCESS! It's like my code wasn't there at all. What should I do?

  • calling java script function then C# function after clicking ASP.NET button

    - by Eyla
    I have this serious: I have ASP.NET page, This page contents Update panel with ASP.NET control. I have Java script function to do validation so when I click the button I will use onclientclick to call the java function to do the validation and after this one done should call then event click button function from code behind. I tried vew methods but they did not work for me. here is sample of my code that after I click the button onclientclick will call the java script function for validation and if the validation is OK should call onclick event. .................... java script function ........................ <script type="text/javascript" > function add(){ if (tag == trye) { document.getElementById('<%=btnInfor.ClientID%>').click(); alert("DataAdded") } else { alert("Requiered Field Missing.") return false; } } </script> .....................

  • How to properly set button phase after dragging over button?

    - by irobeth
    I have a class (mxml) that extends Button while implementing drag/drop support. When I drag one of them onto another, the drag receiver stays stuck in its 'over' phase until I click on it (As if something about DragManager.acceptDragDrop is preventing the MouseEvent from getting to button) Is there a way to make a button re-evaluate its phase after the drop? I've tried fabricating a MouseEvent and sending it to rollOverHandler with no luck. This resembles the scenario in Button.as (lines 2606-2647) described like Drag over and up mouse down while out of Button roll over Button - stay in "up" phase mouse up while over Button - "over" phase continue with step 2 of first three sequences above This is my drag/drop handler private function dragDropHandler(event:DragEvent):void { trace("dropped"); var ib : IconButton = (event.dragInitiator as IconButton); if(this.data is Section) { if(ib.data is Item) { trace("ITEM"); //move an item into a section. var ae : AldonaEvent = new AldonaEvent(AldonaEvent.MOVE); ae.data = ib.data; dispatchEvent(ae); } else if(ib.data is Section) { trace("SECTION"); //change a section's parent. var ae : AldonaEvent = new AldonaEvent(AldonaEvent.MOVE); ae.data = ib.data; dispatchEvent(ae); } } //you can only drag stuff into sections. }

  • How can I find out if the MainActivity is being paused from my Java class?

    - by quinestor
    I am using motion sensor detection in my application. My design is this: a class gets the sensor services references from the main activity and then it implements SensorEventListener. That is, the MainActivity does not listen for sensor event changes: public void onCreate(Bundle savedInstanceState) { // ... code mSensorManager = (SensorManager) getSystemService(Context.SENSOR_SERVICE); mAccelerometer = mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER); // The following is my java class, it does not extends any android fragment/activty mShakeUtil = new ShakeUtil(mSensorManager,mAccelerometer,this); // ..more code.. } I can't redesign ShakeUtil so it is a fragment nor activity, unfortunately. Now to illustrate the problem consider: MainActivity is on its way to be destroyed/paused. I.e screen rotation ShakeUtil's onSensorChanged(SensorEvent event) gets called in the process.. One of the things that happen inside onSensorChanged is a dialog interaction, which gives the error: java.lang.IllegalStateException: Can not perform this action after onSaveInstanceState When the previous happens between MainActivity's onSaveInstanceState and onPause. I know this can be prevented if I successfully detect that MainActivity is being pause in ShakeUtil. How can I detect that MainActivity is being paused or onSaveInstanceState was called from ShakeUtil? Alternatively, how can I avoid this issue without making Shakeutil extend activity? So far I have tried with flag variables but that isn't good enough, I guess these are not atomic operations. I tried using Activity's isChangingConfigurations(), but I get an undocummented "NoSuchMethodFound" error.. I am unregistering the sensors by calling ShakeUtil when onPause in main ACtivity

  • ASP.NET AJAX weirdness

    - by LoveMeSomeCode
    Ok, I thought I understood these topics well, but I guess not, so hopefully someone here can clear this up. Page.IsAsync seems to be broken. It always returns false. But ScriptManager.IsInAsyncPostBack seems to work, sort of. It returns true during the round trip for controls inside UpdatePanels. This is good; I can tell if it's a partial postback or a regular one. ScriptManager.IsInAsyncPostBack returns false however for async Page Methods. Why is this? It's not a regular postback, I'm just calling a public static method on the page. It causes a problem because I also realized that if you have a control with AutoPostBack = false, it won't trigger a postback on it's own, but if it has an event handler on the page, that event handler code WILL run on the next postback, regardless of how the postback occurred, IF the value has changed. i.e. if I tweak a dropdown and then hit a button, that dropdown's handler code will fire. This is ok, except that it will also happen during Page Method calls, and I have no way to know the difference. Any thoughts?

  • Does/Will autofac's ASP.NET integration support PreInit or Init events?

    - by David Rubin
    I see from poking around in the 1.4.4 source that Autofac's ASP.NET integration (via Autofac.Integration.Web) peforms injection of properties on the Page as part of the HttpContext.PreRequestHandlerExecute event handling, but that the page's child controls don't get their properties injected until Page.PreLoad. What this means, though is that the injected properties of child controls are unavailable for use in the OnInit event handler. For example, this works fine: HelloWorld.aspx: <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="HelloWorld.aspx.cs" Inherits="HelloWorld" %> <html> <body> <asp:Label runat="server" id="lblMsg" OnInit="HandleInit"/> </body> </html> HelloWorld.aspx.cs: ... protected void HandleInit() { lblMsg.Text = _msgProvider.GetMessage(); } public IMsgProvider _msgProvider { private get; set; } // <-- Injected But changing the HelloWorld Page to a UserControl (.acsx) and putting the UserControl in another page doesn't work because _msgProvider isn't injected early enough. Is there a way to make Autofac inject properties of child controls earlier? Or is this something that can be addressed in a future build? Thanks!

  • MS Access (Jet) transactions, workspaces & scope

    - by Eric G
    I am having trouble with committing a transaction (using Access 2003 DAO). It's acting as if I never had called BeginTrans -- I get error 3034 on CommitTrans, "You tried to commit or rollback a transaction without first beginning a transaction"; and the changes are written to the database (presumably because they were never wrapped in a transaction). However, BeginTrans is run, if you step through it. I am running it within the Access environment using the DBEngine(0) workspace. The tables I'm updating are all opened via a Jet database connection (to the same database) and updated using DAO.Recordset.update. The connection is opened before starting BeforeTrans. I'm not doing anything weird in the middle of the transaction like closing/opening connections or multiple workspaces etc. There is one nested transaction level (basically it's wrapping multiple transacted updates in an outer transaction, so if any fail they all fail). The inner transactions run without errors, it's the outer transaction that doesn't work. Here are a few things I've looked into and ruled out: The transaction is spread across several methods and BeginTrans and CommitTrans (and Rollback) are all in different places. But when I tried a simple test of running a transaction this way, it doesn't seem like this should matter. I thought maybe the database connection gets closed when it goes out of local scope, even though I have another 'global' reference to it (I'm never sure what DAO does with dbase connections to be honest). But this seems not to be the case -- right before the commit, the connection and its recordsets are alive (I can check their properties, EOF = False, etc.) My CommitTrans and Rollback are done within event callbacks. (Very basically, a parser program is throwing an 'onLoad' or 'onLoadFail' event at the end of parsing, which I am handling by either committing or rolling back the inserts I made during processing.) However, again, trying a simple test, it doesn't seem like this should matter. Any ideas why this isn't working for me? Thanks.

  • sorting a gridview alphabetically when columns are codes

    - by nat
    hi there i have a gridview populated by a Web Service search function. some of the columns in the grid are templatefields, because the values coming back from the search (in a datatable) are ids - i then use these ids to lookup the values when the rowdatabound event is triggered and populate a label or some such. this means that my sorting function for these id/lookup columns sorts by the ids rather than the textual value that i have looked up and actually populated the grid with (although i do put the ids in the grids datakeys). what i want to do is top be able to sort by the looked up textual value rather than the codes for these particular columns. what i was going to do to get around this was to when the datatable comes back from the search, adding more columns the textual values and doing all the looking up then, thus being able to sort directly from the manually added columns. is there another way to do this? as that approach seems like a bit of a bodge. although i guess it does remove having to do the looking up in the rowdatabound event.... my sorting function works by sticking the datatable in the session and on each bind grabbing the sort column and binding the gridview to a DataView with the sort attribute set to the column - and the direction. thanks nat

  • Best practice to create WPF wrapper application displaying screens on demand.

    - by Robbie
    Context: I'm developing a WPF application which will contain a lot of different "screens". Each screen contains a which on its turn contains all the visual elements. Some elements trigger events (e.g., checkboxes), a screen has individual resources, etc. The main application is "wrapper" around these screens: it contains a menubar, toolbar, statusbar and alike (in a DockPanel) and space to display one screen. Through the menubar, the user can choose which screen he wants to display. Goal: I want to dynamically load & display & (event)handle one screen in the space in the main application. I don't want to copy & paste all the "wrapper" stuff in all the different screens. And As I have many complex screens (around 300 - luckily auto-generated), I don't want to load all of them at the start of the application, but only upon request. Question: What do you recommend as the best way to realize this? What kind of things should I use and investigate: Pages or windows or User Control for the screens? Does this affect the event handling?

  • MUD (game) design concept question about timed events.

    - by mudder
    I'm trying my hand at building a MUD (multiplayer interactive-fiction game) I'm in the design/conceptualizing phase and I've run into a problem that I can't come up with a solution for. I'm hoping some more experienced programmers will have some advice. Here's the problem as best I can explain it. When the player decides to perform an action he sends a command to the server. the server then processes the command, determines whether or not the action can be performed, and either does it or responds with a reason as to why it could not be done. One reason that an action might fail is that the player is busy doing something else. For instance, if a player is mid-fight and has just swung a massive broadsword, it might take 3 seconds before he can repeat this action. If the player attempts to swing again to soon, the game will respond indicating that he must wait x seconds before doing that. Now, this I can probably design without much trouble. The problem I'm having is how I can replicate this behavior from AI creatures. All of the events that are being performed by the server ON ITS OWN, aka not as an immediate reaction to something a player has done, will have to be time sensitive. Some evil monster has cast a spell on you but must wait 30 seconds before doing it again... I think I'll probably be adding all these events to some kind of event queue, but how can I make that event queue time sensitive?

  • Recursive QuickSort suffering a StackOverflowException -- Need fresh eyes

    I am working on a Recursive QuickSort method implementation in a GenericList Class. I will have a second method that accepts a compareDelegate to compare different types, but for development purposes I'm sorting a GenericList<int I am recieving stackoverflow areas in different places depending on the list size. I've been staring at and tracing through this code for hours and probably just need a fresh pair of (more experienced)eyes.

  • Lost in dates and timezones

    - by Sebastien
    I'm working on an application that stores conferences with their start and end date. Up until now, I was developing in Belgium and my server is in France, so everything is in the same timezone, no problem. But today, I'm in San Francisco, my server is in France and I noticed I have a bug. I'm setting dates from a Flex client (ActionScript automatically adapts date display according to client local timezone, which is GMT-8 for me today. My server runs on Hibernate and MySQL in France (GMT+1). So when I look at my database using phpMyAdmin, I see a date set to "2010-06-07 00:00:01" but in my Flex client it displays "2010-06-06 15:00:01". Ultimately, what I want is that the dates are displayed in the local timezone of the event, which is the date I set it to. So when I'm in Belgium and I set the start date of an event to be "2010-06-07 00:00:01" I want to retrieve it that way. But I'm lost as to what layer adapts what. Is timezone stored in DATETIME MySQL columns (I can't see it in MySQL)? Does Hibernate to anything to it when it transfers it to java.lang.Date that has Timezone information? And ultimately, what is the best way to solve this mess?

  • Browser freezes when try to call a JS function along with submission of a form.

    - by Waseem
    I have form in my view like following 1 <div> 2 <% form_tag facebook_user_path do %> 3 <label>Use my photo and name from facebook?</label><br /> 4 <%= check_box_tag 'use_name_and_photo', 'yes', true %> 5 <img src="<%= @user.pic %>" /><% @user.name %> 6 7 <%= submit_tag "Finish", :id => "use_name_and_photo_submit" %> 8 <% end %> 9 </div> I have attached some JS handlers using Jquery to this form. 1 var fb = { 2 extendedPermissions: function () { 3 $("#use_name_and_photo_submit").click(function (event) { 4 FB.Connect.showPermissionDialog("email,read_stream,publish_stream", function (perms) { 5 if (!perms) { 6 alert("You have to grant facebook extended permissions to further browse the application."); 7 } else { 8 $("form").submit(function () { 9 $.post($(this).attr("action"), $(this).serialize(), null, "script"); 10 }); 11 } 12 }); 13 event.preventDefault(); 14 return false; 15 }); 16 } 17 }; 18 19 $(document).ready(function () { 20 fb.extendedPermissions(); 21 }); What I want is that when the user clicks on the "Finish" button, he is prompted for the facebook permissions dialogue and when he gives the permissions, the form is submitted to FacebookUsersController. Right now when I click the "Finish" button, facebook permissions dialogue is initiated but before I am prompted for the actual permission submission window, the browser freezes. Just like I have pressed Esc during the process. In fact status bar of the browser says "Stopped". Any help is highly appreciated.

  • Inline function and global variable issue in Javascript

    - by Natim
    I have some code here : http://bitbucket.org/natim/lo53_tp1/src/tip/part3/camions/medias/js/tracking.js That I use to draw some information about trucks direction. The problem come from a function defined in a for loop like this one : ... for(i = 0; i < nb_trucks; i++) { ... contentString = '<div id="content">'+ trucks[i]['name'] + '</div>'; current_window = new google.maps.InfoWindow({ content: contentString }); infosWindow.push(current_window); current_marker = new google.maps.Marker({ map: map, position: new google.maps.LatLng(trucks[i]['end']['lat'], trucks[i]['end']['lon']), draggable: false, title: trucks[i]['name'] }); markers.push(current_marker); google.maps.event.addListener(current_marker, 'click', function() { current_window.open(map, current_marker); }); } In this code, you can see the last block google.maps.event.addListener(current_marker, 'click', function() { current_window.open(map, current_marker); }); And my problem is that current_marker in the addListener parameters is different from the one inside the function. The current_window and the current_marker inside the function is overide at each loop turn. How can I get it right ? Thanks
