  • how to close popup using javascript with xml formatting

    - by Michael Robinson
    I bought this program that created a pretty nice imageuploader flash script however I can't get the Javascript function close window to close the popup and redirect the original page. here is the XML piece that defines the url's: <urls urlToUpload="upload.php?" urlOnUploadSuccess="http://www.home.com/purchase.html" urlOnUploadFail="http://www.home.com/tryagain.html" urlUpdateFlashPlayer="http://www.home.com/flashalternative.html" jsFunctionNameOnUpload=""/> This last line calls a javascript function on upload. The problem is I don't know what to call and where to put it. Here is the HTML file that is the popup: <HEAD> <title>Baublet Uploader</title> <script type="text/javascript" src="swfobject.js"></script> </HEAD> <BODY> <!-- Q-ImageUploader www.quadroland.com --> <div id="QImageUploader"> Flash Player stuff here </div> <script type="text/javascript"> // <![CDATA[ var so = new SWFObject("q_image_uploader.swf", "imageuploader", "650", "430", "9", "#FFFFFF"); so.addParam("scale", "noscale"); so.addParam("salign", "TL"); so.addVariable("AdditionalStringVariable","pass additional data here"); so.write("QImageUploader"); // ]]> </script> I found this Closing script I thought might work: <script language="javascript"> function close_window(page) { window.opener.location.href=page setTimeout(function(){window.close()},10); } </script> Does this go into the Popup HTML page above or would it be a separate close.js file in the root? Thanks, I'm really confused.

  • zeroclipboard does not work when loaded with ajax call

    - by kylex
    I have the following code which works the way one would expect (click on the button and it copies the text in the input box): <script type="text/javascript" src="ABSOLUTE_LINK/ZeroClipboard.js"></script> <script type="text/javascript"> ZeroClipboard.setMoviePath( 'ABSOLUTE_LINK/ZeroClipboard.swf' ); </script> Copy to Clipboard: <input type="text" id="clip_text" size="40" value="Copy me!"/><br/><br/> <div id="d_clip_button">Copy To Clipboard</div> <script language="JavaScript"> echo "var clip = new ZeroClipboard.Client(); clip.setText( '' ); // will be set later on mouseDown clip.setHandCursor( true ); clip.setCSSEffects( true ); clip.addEventListener( 'load', function(client) { } ); clip.addEventListener( 'complete', function(client, text) { alert("Copied text to clipboard: " + text ); } ); clip.addEventListener( 'mouseOver', function(client) { } ); clip.addEventListener( 'mouseOut', function(client) { } ); clip.addEventListener( 'mouseDown', function(client) { // set text to copy here clip.setText( document.getElementById('clip_text').value ); } ); clip.addEventListener( 'mouseUp', function(client) { } ); clip.glue( 'd_clip_button' ); </script> However, when this code is loaded using an ajax call, the functionality disappears. Is there anything I can do to get this working when it's called via ajax?

  • Can I copy/clone a function in JavaScript?

    - by Craig Stuntz
    I'm using jQuery with the validators plugin. I would like to replace the "required" validator with one of my own. This is easy: jQuery.validator.addMethod("required", function(value, element, param) { return myRequired(value, element, param); }, jQuery.validator.messages.required); So far, so good. This works just fine. But what I really want to do is call my function in some cases, and the default validator for the rest. Unfortunately, this turns out to be recursive: jQuery.validator.addMethod("required", function(value, element, param) { // handle comboboxes with empty guids if (someTest(element)) { return myRequired(value, element, param); } return jQuery.validator.methods.required(value, element, param); }, jQuery.validator.messages.required); I looked at the source code for the validators, and the default implementation of "required" is defined as an anonymous method at jQuery.validator.messages.required. So there is no other (non-anonymous) reference to the function that I can use. Storing a reference to the function externally before calling addMethod and calling the default validator via that reference makes no difference. What I really need to do is to be able to copy the default required validator function by value instead of by reference. But after quite a bit of searching, I can't figure out how to do that. Is it possible? If it's impossible, then I can copy the source for the original function. But that creates a maintenance problem, and I would rather not do that unless there is no "better way."

  • Full text index requires dropping and recreating - why?

    - by Amjid Qureshi
    Hi all, So I've got a web app running on .net 3.5 connected to a SQL 2005 box. We do scheduled releases every 2 weeks. About 14 tables out of 250 are full text indexed. After not every release, but a few too many, the indexes crap out. They seem to have data in there, but when we try to search them from the front end or SQL enterprise we get timeouts/hangs. We have a script that disables the indexes, drops them, deletes the catalog and then re creates the indexes. This fixes the problem 99 times out of 100. and the one other time, we run the script again and it all works We have tried just rebuilding the fulltext index but that doesn't fix the issue. My question is why do we have to do this ? what can we do to sort the index out? Here is a bit of the script, IF EXISTS (SELECT * FROM sys.fulltext_indexes fti WHERE fti.object_id = OBJECT_ID(N'[dbo].[Address]')) ALTER FULLTEXT INDEX ON [dbo].[Address] DISABLE GO IF EXISTS (SELECT * FROM sys.fulltext_indexes fti WHERE fti.object_id = OBJECT_ID(N'[dbo].[Address]')) DROP FULLTEXT INDEX ON [dbo].[Address] GO IF EXISTS (SELECT * FROM sysfulltextcatalogs ftc WHERE ftc.name = N'DbName.FullTextCatalog') DROP FULLTEXT CATALOG [DbName.FullTextCatalog] GO -- may need this line if we get an error BACKUP LOG SMS2 WITH TRUNCATE_ONLY CREATE FULLTEXT CATALOG [DbName.FullTextCatalog] ON FILEGROUP [FullTextCatalogs] IN PATH N'F:\Data' AS DEFAULT AUTHORIZATION [dbo] CREATE FULLTEXT INDEX ON [Address](CommonPlace LANGUAGE 'ENGLISH') KEY INDEX PK_Address ON [DbName.FullTextCatalog] WITH CHANGE_TRACKING AUTO go

  • JAVA vs .NET - Choice for way to go further [closed]

    - by Sarang
    I have my subject .Net acedemically. I also learned core Java and did a project as well. I took training from a Java firm. Now, as a skill I do have knowledge as both language. But, it is creating a large problem to me that, which field I should chhose? Even if having better OOP fundamentals, will it be easier for me to transfer from one to another in the future ? Please suggest me a way. Also, we do have may technologies available at both side, like JSP, JSF, J2ME, Share Point, SilverLight etc. Which is better as per their reliabity point of view? Which are fast growing and useful technologies used mostly in current IT corporate world ? Are they easier to learn at fresher's point of view? Please answer. Perhaps, this answer may help me mostly to create my way to learn them and go further. Every IT developer, please help to find me my way.

  • How do I do nested transactions in NHibernate?

    - by Gavin Schultz-Ohkubo
    Can I do nested transactions in NHibernate, and how do I implement them? I'm using SQL Server 2008, so support is definitely in the DBMS. I find that if I try something like this: using (var outerTX = UnitOfWork.Current.BeginTransaction()) { using (var nestedTX = UnitOfWork.Current.BeginTransaction()) { ... do stuff nestedTX.Commit(); } outerTX.Commit(); } then by the time it comes to outerTX.Commit() the transaction has become inactive, and results in a ObjectDisposedException on the session AdoTransaction. Are we therefore supposed to create nested NHibernate sessions instead? Or is there some other class we should use to wrap around the transactions (I've heard of TransactionScope, but I'm not sure what that is)? I'm now using Ayende's UnitOfWork implementation (thanks Sneal). Forgive any naivety in this question, I'm still new to NHibernate. Thanks! EDIT: I've discovered that you can use TransactionScope, such as: using (var transactionScope = new TransactionScope()) { using (var tx = UnitOfWork.Current.BeginTransaction()) { ... do stuff tx.Commit(); } using (var tx = UnitOfWork.Current.BeginTransaction()) { ... do stuff tx.Commit(); } transactionScope.Commit(); } However I'm not all that excited about this, as it locks us in to using SQL Server, and also I've found that if the database is remote then you have to worry about having MSDTC enabled... one more component to go wrong. Nested transactions are so useful and easy to do in SQL that I kind of assumed NHibernate would have some way of emulating the same...

  • Extending timeout and message size in WCF service generated by Biztalk 2006 R2

    - by Sergej Andrejev
    Hi, I'm generating WCF service using Biztalk. The code I get is this: <system.serviceModel> <behaviors> <serviceBehaviors> <behavior name="ServiceBehaviorConfiguration"> <serviceDebug httpHelpPageEnabled="true" httpsHelpPageEnabled="false" includeExceptionDetailInFaults="false" /> <serviceMetadata httpGetEnabled="true" httpsGetEnabled="false" externalMetadataLocation="" /> </behavior> </serviceBehaviors> </behaviors> <services> <!-- Note: the service name must match the configuration name for the service implementation. --> <service name="Microsoft.BizTalk.Adapter.Wcf.Runtime.BizTalkServiceInstance" behaviorConfiguration="ServiceBehaviorConfiguration"> <endpoint name="HttpMexEndpoint" address="mex" binding="mexHttpBinding" bindingConfiguration="" contract="IMetadataExchange" /> <!--<endpoint name="HttpsMexEndpoint" address="mex" binding="mexHttpsBinding" bindingConfiguration="" contract="IMetadataExchange" />--> </service> </services> </system.serviceModel> Maybe it's not the most beautifull configuration, but it works. The problem is I don't know how to modify timeouts and message max size, because it has only mex endpoint. I'm surprised how this works at all with just mex endpoint. So two questions are: Why does this works at all? What should I add to extend timeouts and message size?

  • Using GKPeerPickerController within a selector from a Cocos2D CCMenuItem

    - by Mark Hazlett
    Hey everyone, So i'm trying to use GameKit along with Cocos2D so that when a user clicks on the multiplayer menu item it will display the GKPeerPickerController. I'm however, running into some snags. It doesn't seem to want to compile. However, it doesn't give me an error inside of the code that's in my selector. Anyways here's the code... @implementation GameOverLayer - (id) init { self = [super init]; if (self != nil) { [CCMenuItemFont setFontSize:20]; [CCMenuItemFont setFontName:@"Helvetica"]; CCMenuItem *start = [CCMenuItemFont itemFromString:@"Play Again!" target:self selector:@selector(startGame:)]; CCMenuItem *connect = [CCMenuItemFont itemFromString:@"Multiplayer" target:self selector:@selector(connect:)]; CCMenu *menu = [CCMenu menuWithItems:start,connect, nil]; [menu alignItemsVertically]; [self addChild:menu]; } return self; } -(void)startGame: (id)sender { [[CCDirector sharedDirector] replaceScene: [HelloWorld scene]]; } -(void)connect: (id)sender { GKPeerPickerController *peerPicker; peerPicker = [[GKPeerPickerController alloc] init]; peerPicker.delegate = self; peerPicker.connectionTypesMask = GKPeerPickerConnectionTypeOnline | GKPeerPickerConnectionTypeNearby; [peerPicker show]; } @end The error message i'm getting is...

  • How to properly implement cheat codes?

    - by Axarydax
    Hi, what would be the best way to implement kind of cheat codes in general? I have WinForms application in mind, where a cheat code would unlock an easter egg, but the implementation details are not relevant. The best approach that comes to my mind is to keep index for each code - let's consider famous DOOM codes - IDDQD and IDKFA, in a fictional C# app. string[] CheatCodes = { "IDDQD", "IDKFA"}; int[] CheatIndexes = { 0, 0 }; const int CHEAT_COUNT = 2; void KeyPress(char c) { for (int i = 0; i < CHEAT_COUNT; i++) //for each cheat code { if (CheatCodes[i][CheatIndexes[i]] == c) { //we have hit the next key in sequence if (++CheatIndexes[i] == CheatCodes[i].Length) //are we in the end? { //Do cheat work MessageBox.Show(CheatCodes[i]); //reset cheat index so we can enter it next time CheatIndexes[i] = 0; } } else //mistyped, reset cheat index CheatIndexes[i] = 0; } } Is this the right way to do it?

  • Experiences with (free) embedded TCP / IP stacks?

    - by Dan
    Does anyone have especially good (or bad) experiences with any of the following embedded TCP / IP stacks? uIP lwIP Bentham's TCP/IP Lean implementation The TCP/IP stack from this book My needs are for a solid, easy-to-port stack. Code size isn't terribly important, performance is relatively important, but ease of use & porting is very important. The system will probably use an RTOS, that hasn't been decided, but in my experience most stacks can be used with or without an RTOS. Most likely the platform will be an ARM variant (ARM7 or CM3 in all likelihood). Not too concerned about bolting the stack to the Ethernet driver, so that isn't a big priority in the selection. I'm not terribly interested in extracting a stack out of an OS, such as Linux, RTEMS, etc. I'm also not interested in commercial offerings such as Interniche, Micrium, etc... The stack doesn't need all sorts of bells & whistles, doesn't need IPv6, and I don't need any stuff on top of it (web servers, FTP servers, etc..) In fact it's possible that I'll only use UDP, although I can envision a couple scenarios where TCP would be preferable. Experiences with other stacks I've missed are of course also very much of interest. Thanks for your time & input.

  • Clojure agents consuming from a queue

    - by erikcw
    I'm trying to figure out the best way to use agents to consume items from a Message Queue (Amazon SQS). Right now I have a function (process-queue-item) that grabs an items from the queue, and processes it. I want to process these items concurrently, but I can't wrap my head around how to control the agents. Basically I want to keep all of the agents busy as much as possible without pulling to many items from the Queue and developing a backlog (I'll have this running on a couple of machines, so items need to be left in the queue until they are really needed). Can anyone give me some pointers on improving my implementation? (def active-agents (ref 0)) (defn process-queue-item [_] (dosync (alter active-agents inc)) ;retrieve item from Message Queue (Amazon SQS) and process (dosync (alter active-agents dec))) (defn -main [] (def agents (for [x (range 20)] (agent x))) (loop [loop-count 0] (if (< @active-agents 20) (doseq [agent agents] (if (agent-errors agent) (clear-agent-errors agent)) ;should skip this agent until later if it is still busy processing (not sure how) (send-off agent process-queue-item))) ;(apply await-for (* 10 1000) agents) (Thread/sleep 10000) (logging/info (str "ACTIVE AGENTS " @active-agents)) (if (> 10 loop-count) (do (logging/info (str "done, let's cleanup " count)) (doseq [agent agents] (if (agent-errors agent) (clear-agent-errors agent))) (apply await agents) (shutdown-agents)) (recur (inc count)))))

  • C - Complicated pointer declarations - help understanding

    - by Emmel
    In my burgeoning new self-education in the C language, I've come across a set of declarations that I do not understand how to read. I'd love for someone to break these down. I'll explain at the bottom where I got these examples from. 1. char (*(*x())[])() "x: function returning pointer to array[] of pointer to function returning char" - huh? 2. char (*(*x[3])())[5] "x: array[3] of pointer to function returning pointer to array[5] of char" - come again? 3. char **argv This I understand. "Pointer to pointer to char." But what I don't understand is -- what's the use case for a pointer to a pointer? Follow-up question: does anyone every use declarations this complex or is this just academic fun on the part of the authors of the examples I got this from? These examples are from section 5.12 of the K&R book. This is the first time I'm genuinely stumped by an explanation, in an otherwise well-written classic. Thanks.

  • Official names for pointer operators

    - by FredOverflow
    What are the official names for the operators * and & in the context of pointers? They seem to be frequently called dereference operator and address-of operator respectively, but unfortunately, the section on unary operators in the standard does not name them. I really don't want to name & address-of anymore, because & returns a pointer, not an address. (A pointer is a language mechanism, while an address is an implementation detail. Addresses are untyped, while pointers aren't, except for void*.) The standard is very clear about this: The result of the unary & operator is a pointer to its operand. Symmetry suggests to name & reference operator which is a little unfortunate because of the collision with references in C++. The fact that & returns a pointer suggests pointer operator. Are there any official sources that would confirm these (or other) namings?

  • ActionScript 3.0: placing code on stage/MC timelines a la AS2 instead of in classes

    - by BoltClock
    I'm aware that ActionScript 3.0 is designed from the ground up to be a largely object-oriented language and using it means less or even no timeline code in Flash documents. I'm quite experienced with OOP and am comfortable writing classes. However, since I mostly use Flash for animations, I hardly ever need to write ActionScript code other than for preloaders, subtitles, quality controls, website links and so on. In fact, I still set my Flash movies to use AS2 to this day because I'm used to gotoAndPlay()/gotoAndStop(), AS2 preloaders, subtitles, quality controls and even getURL(). Of course, I really want to move on now that practically everyone's on Flash Player 9 or 10 and now that I've dabbled with other OO languages like Java, C# and Objective-C too. I'm a complete newcomer to AS3 and am not very learned with AS2 either. Considering my current use of ActionScript, are there any cases where it's still OK to use very simple AS3 code in the timeline instead of moving code to a class, especially since moving to a class might mean unnecessarily increasing the number of LOC from 4 to 40? (Heck, is the latter case ('instead of ...') even a valid concern at all?)

  • Resize a UITableView to accomodate a translucent header before it becomes visible

    - by scotru
    I have a UITableView inside a UINavigationController. The navigation controller uses a translucent navigation bar--as a result, my table view is displayed behind the navigation bar and it's height includes the height of the navigation bar. However, I want the table view to appear below the navigation bar (as it would if it were not translucent). I'm working in MonoTouch, but I think the principles are language independent. Here's the code I'm using to resize the UITableView frame: RectangleF rect = tableView.Frame; tableView.Frame = new RectangleF (rect.Left, rect.Top + 44, rect.Width, rect.Height - 44); tableView.ContentInset = new UIEdgeInsets (0, 0, 0, 0); This works fine if I place it in the viewDidAppear method, but will not work in the viewWillAppear method. In the viewDidAppear method, however I can see the resize occurring briefly in the form of a flicker. I want to do the resize before the frame appears. But if I put this code in viewWillAppear or viewDidLoad, it has no effect. Thanks in advance for any help!

  • Mocking with Boost::Test

    - by Billy ONeal
    Hello everyone :) I'm using the Boost::Test library for unit testing, and I've in general been hacking up my own mocking solutions that look something like this: //In header for clients struct RealFindFirstFile { static HANDLE FindFirst(LPCWSTR lpFileName, LPWIN32_FIND_DATAW lpFindFileData) { return FindFirstFile(lpFileName, lpFindFileData); }; }; template <typename FirstFile_T = RealFindFirstFile> class DirectoryIterator { //.. Implementation } //In unit tests (cpp) #define THE_ANSWER_TO_LIFE_THE_UNIVERSE_AND_EVERYTHING 42 struct FakeFindFirstFile { static HANDLE FindFirst(LPCWSTR lpFileName, LPWIN32_FIND_DATAW lpFindFileData) { return THE_ANSWER_TO_LIFE_THE_UNIVERSE_AND_EVERYTHING; }; }; BOOST_AUTO_TEST_CASE( MyTest ) { DirectoryIterator<FakeFindFirstFile> LookMaImMocked; //Test } I've grown frustrated with this because it requires that I implement almost everything as a template, and it is a lot of boilerplate code to achieve what I'm looking for. Is there a good method of mocking up code using Boost::Test over my Ad-hoc method? I've seen several people recommend Google Mock, but it requires a lot of ugly hacks if your functions are not virtual, which I would like to avoid. Oh: One last thing. I don't need assertions that a particular piece of code was called. I simply need to be able to inject data that would normally be returned by Windows API functions.

  • UnsatisfiedLinkError: The specified procedure could not be found

    - by matt
    I'm writing some JNI code in C++ to be called from an applet on Windows XP. I've been able to successfully run the applet and have the JNI library loaded and called, even going so far as having it call functions in other DLLs. I got this working by setting up the PATH system environment variable to include the directory all of my DLLs are in. So, the problem, is that I add another call that uses a new external DLL, and suddenly when loading the library, an UnsatisfiedLinkError is thrown. The message is: 'The specified procedure could not be found'. This doesn't seem to be a problem with a missing dependent DLL, because I can remove a dependent DLL and get a different message about dependent DLL missing. From what I've been able to find online, it appears that this message means that a native Java function implementation is missing from the DLL, but it's odd that it works fine without this extra bit of code. Does anyone know what might be causing this? What kinds of things can give a 'The specified procedure could not be found' messages for an UnsatisifedLinkError?

  • CQRS - The query side

    - by mattcodes
    A lot of the blogsphere articles related to CQRS (command query repsonsibility) seperation seem to imply that all screens/viewmodels are flat. e.g. Name, Age, Location Of Birth etc.. and thus the suggestion that implementation wise we stick them into fast read source etc.. single table per view mySQL etc.. and pull them out with something like primitive SqlDataReader, kick that nasty nhibernate ORM etc.. However, whilst I agree that domain models dont mapped well to most screens, many of the screens that I work with are more dimensional, and Im sure this is pretty common in LOB apps. So my question is how are people handling screen where by for example it displays a summary of customer details and then a list of their orders with a [more detail] link etc.... I thought about keeping with the straight forward SQL query to the Query Database breaking off the outer join so can build a suitable ViewModel to View but it seems like overkill? Alternatively (this is starting to feel yuck) in CustomerSummaryView table have a text/big (whatever the type is in your DB) column called Orders, and the columns for the Order summary screen grid are seperated by , and rows by |. Even with XML datatype it still feeel dirty. Any thoughts on an optimal practice?

  • What is the correct way to create dynamic javascript in ASP.net MVC2?

    - by sabbour
    I'm creating a Google Maps partial view/user control in my project that is passed a strongly typed list of objects containing latitude and longitude values. Currently, this is the code I have for the partial: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<IEnumerable<Project.Models.Entities.Location>>" %> <!-- Place for google to put the map --> <div id="report_map_canvas" style="width: 100%; height: 728px; margin-bottom: 2px;"> </div> <script type='text/javascript'> google.load("maps", "2"); $(document).ready(initializeMap); function initializeMap() { if (GBrowserIsCompatible()) { var map = new GMap2(document.getElementById('report_map_canvas')); map.setCenter(new GLatLng(51.5, -0.1167), 2); <% foreach (var item in Model) { %> map.addOverlay(new GMarker(new GLatLng('<%= Html.Encode(item.latitude)%>','<%= Html.Encode(item.longitude)%>'),{ title: '<%= Html.Encode(String.Format("{0:F}",item.speed)) %> km/h '})); <% } %> map.setUIToDefault(); } } </script> Is it right to dynamically create the javascript file this way by looping over the list and emitting javascript? Is there a better way to do it?

  • Solving problems involving more complex data structures with CUDA

    - by Nils
    So I read a bit about CUDA and GPU programming. I noticed a few things such that access to global memory is slow (therefore shared memory should be used) and that the execution path of threads in a warp should not diverge. I also looked at the (dense) matrix multiplication example, described in the programmers manual and the nbody problem. And the trick with the implementation seems to be the same: Arrange the calculation in a grid (which it already is in case of the matrix mul); then subdivide the grid into smaller tiles; fetch the tiles into shared memory and let the threads calculate as long as possible, until it needs to reload data from the global memory into shared memory. In case of the nbody problem the calculation for each body-body interaction is exactly the same (page 682): bodyBodyInteraction(float4 bi, float4 bj, float3 ai) It takes two bodies and an acceleration vectors. The body vector has four components it's position and the weight. When reading the paper, the calculation is understood easily. But what is if we have a more complex object, with a dynamic data structure? For now just assume that we have an object (similar to the body object presented in the paper) which has a list of other objects attached and the number of objects attached is different in each thread. How could I implement that without having the execution paths of the threads to diverge? I'm also looking for literature which explains how different algorithms involving more complex data structures can be effectively implemented in CUDA.

  • Umlaute from JSP-page are misinterpreted

    - by Karin
    I'm getting Input from a JSP page, that can contain Umlaute. (e.g. Ä,Ö,Ü,ä,ö,ü,ß). Whenever an Umlaut is entered in the Input field an incorrect value gets passed on. e.g. If an "ä" (UTF-8:U+00E4) gets entered in the input field, the String that is extracted from the argument is "ä" (UTF-8: U+00C3 and U+00A4) It seems to me as if the UTF-8 hex encoding (which is c3 a4 for an "ä") gets used for the conversion. How can I retrieved the correct value? Here are snippets from the current implementation The JSP-page passes the input value "pk" on to the processing logic: <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> ... <input type="text" name="<%=pk.toString()%>" value="<%=value%>" size="70"/> <button type="submit" title="Edit" value='Save' onclick="action.value='doSave';pk.value='<%=pk.toString()%>'"><img src="icons/run.png"/>Save</button> The value gets retrieved from args and converted to a string: UUID pk = UUID.fromString(args.get("pk")); //$NON-NLS-1$ String value = args.get(pk.toString()); Note: Umlaute that are saved in the Database get displayed correctly on the page.

    Hello, I am writing this code in html: <!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> <script language="javascript" type="text/javascript"> function setVisibility(id, visibility) { document.getElementById(id).style.display = visibility; } </script> <title>Welcome to the memory game</title> </head> <body> <h1>Welcome to the memory game!</h1> <input type="button" name="type" value='Show Layer' onclick="setVisibility('sub3', 'inline');"/> <input type="button" name="type" value='Hide Layer' onclick="setVisibility('sub3', 'none');"/> <div id="sub3">Message Box</div> </body> </html> It suppose to make the "div" disappear and reapper, but it works in chrome and not in explorer. Anyone has any idea how can I make it work in explorer (I tried allowing blocked content when that message about activeX appears in explorer)? Thanks, Greg

  • problem when trying to empty a stack in c

    - by frx08
    Hi all, (probably it's a stupid thing but) I have a problem with a stack implementation in C language, when I try to empty it, the function to empty the stack does an infinite loop.. the top of the stack is never null. where I commit an error? thanks bye! #include <stdio.h> #include <stdlib.h> typedef struct stack{ size_t a; struct stack *next; } stackPos; typedef stackPos *ptr; void push(ptr *top, size_t a){ ptr temp; temp = malloc(sizeof(stackPos)); temp->a = a; temp->next = *top; *top = temp; } void freeStack(ptr *top){ ptr temp = *top; while(*top!=NULL){ //the program does an infinite loop *top = temp->next; free(temp); } } int main(){ ptr top = NULL; push(&top, 4); push(&top, 8); //down here the problem freeStack(&top); return 0; }
