• Simple way to embed an MP3 audio file in a (static) HTML file, starting to play at a specifc time?

  - by Marcel

  Hi all, I want to produce a simple, static HTML file, that has one or more embedded MP3 files in it. The idea is to have a simple mean of listening to specific parts of an mp3 file. On a single click on a visual element, the sound should start to play; However, not from the beginning of the file, but from a specified starting point in that file (and play to the end of the file). This should work all locally from the client's local filesystem, the HTML file and the MP3 files do not reside on a webserver. So, how to play the MP3 audio from a specific starting point? The solution I am looking for should be as simple as possible, while working on most browsers, including IE, Firefox and Safari. Note: I know the <embed> tag as described here, but this seems not to work with my target browsers. Also I have read about jPlayer and other Java-Script-based players, but since I have never coded some JavaScript, I would prefer a HTML-only solution, if possible.

• Core data migration failing with "Can't find model for source store" but managedObjectModel for source is present

  - by Ira Cooke

  I have a cocoa application using core-data, which is now at the 4th version of its managed object model. My managed object model contains abstract entities but so far I have managed to get migration working by creating appropriate mapping models and creating my persistent store using addPersistentStoreWithType:configuration:options:error and with the NSMigratePersistentStoresAutomaticallyOption set to YES. NSDictionary *optionsDictionary = [NSDictionary dictionaryWithObject:[NSNumber numberWithBool:YES] forKey:NSMigratePersistentStoresAutomaticallyOption]; NSURL *url = [NSURL fileURLWithPath: [applicationSupportFolder stringByAppendingPathComponent: @"MyApp.xml"]]; NSError *error=nil; [theCoordinator addPersistentStoreWithType:NSXMLStoreType configuration:nil URL:url options:optionsDictionary error:&error] This works fine when I migrate from model version 3 to 4, which is a migration that involves adding attributes to several entities. Now when I try to add a new model version (version 5), the call to addPersistentStoreWithType returns nil and the error remains empty. The migration from 4 to 5 involves adding a single attribute. I am struggling to debug the problem and have checked all the following; The source database is in fact at version 4 and the persistentStoreCoordinator's managed object model is at version 5. The 4-5 mapping model as well as managed object models for versions 4 and 5 are present in the resources folder of my built application. I've tried various model upgrade paths. Strangely I find that upgrading from an early version 3 - 5 works .. but upgrading from 4 - 5 fails. I've tried adding a custom entity migration policy for migration of the entity whose attributes are changing ... in this case I overrode the method beginEntityMapping:manager:error: . Interestingly this method does get called when migration works (ie when I migrate from 3 to 4, or from 3 to 5 ), but it does not get called in the case that fails ( 4 to 5 ). I'm pretty much at a loss as to where to proceed. Any ideas to help debug this problem would be much appreciated.

  I have a piece of code that sends email.. heres the code This is not working for me.

• Checkbox does not change when clicked directly on it

  - by Matt McCormick

  I have a table of data and have one checkbox per row for the user to select the item. I'm using the following jQuery code to allow the user to select the item by clicking anywhere in the row: $("tbody tr").click(function() { var checkbox = $(this).find(':checkbox'); checkbox.attr('checked', !checkbox.attr('checked')); }); The problem is if I click directly on the checkbox, nothing happens. ie. if the checkbox is not checked, it remains unchecked. If I click anywhere else in the row, the checkbox changes status. I'm thinking that the jQuery code is causing the action to be performed twice. If I click on the checkbox, the checkbox will change but then the jQuery code for clicking on the row will be performed and the checkbox will be changed back. Not sure if that is actually happening but that is my guess. How can I get a checkbox to be toggled when a user clicks on a row and the same thing if they click directly on the checkbox?

• Codeplex/Sourceforge for internal use

  - by Josh

  I'm looking for a free/open source collaborative project manager that can be deployed internally in my workplace that would act similar to Codeplex or Sourceforge. Does anyone know of something like this, and if so do you have experience with it. Requirements: Open Source or Free Locally Deployable Has the same types of features found in Sourceforge / Codeplex Issue/Feature Tracking Community Interaction (ie. Voting, Roles, etc.) SCM Integration (Optional) .NET/Windows Friendly (Optional) Every business ends up having internal utilities, and domain specific apps that developers create to make life easier. Given the input of the internal developer community they have the potential to become much better (can you say GMail...), and I would simply like to foster such an environment internally by providing an easy place for that interaction to take place. UPDATE: So I like what I am seeing in both Trac and GForge, but both are heavily geared towards UNIX/Subversion environments. I should have specified this, but we are a MS shop from top to bottom. How practical do you think it is going to be to try and use these in a MS .NET environment? Would that be like trying to shove a square peg through a round hole?

• Oracle - Getting Select Count(*) from ... as an output parameter in System.Data.OracleClient

  - by cbeuker

  Greetings all, I have a question. I am trying to build a parametrized query to get me the number of rows from a table in Oracle. Rather simple. However I am an Oracle newbie.. I know in SQL Server you can do something like: Select @outputVariable = count(*) from sometable where name = @SomeOtherVariable and then you can set up an Output parameter in the System.Data.SqlClient to get the @outputVariable. Thinking that one should be able to do this in Oracle as well, I have the following query Select count(*) into :theCount from sometable where name = :SomeValue I set up my oracle parameters (using System.Data.OracleClient - yes I know it will be deprecated in .Net 4 - but that's what I am working with for now) as follows IDbCommand command = new OracleCommand(); command.CommandText = "Select count(*) into :theCount from sometable where name = :SomeValue"); command.CommandType = CommandType.Text; OracleParameter parameterTheCount = new OracleParameter(":theCount ", OracleType.Number); parameterTheCount .Direction = ParameterDirection.Output; command.Parameters.Add(parameterTheCount ); OracleParameter parameterSomeValue = new OracleParameter(":SomeValue", OracleType.VarChar, 40); parameterSomeValue .Direction = ParameterDirection.Input; parameterSomeValue .Value = "TheValueToLookFor"; command.Parameters.Add(parameterSomeValue ); command.Connection = myconnectionObject; command.ExecuteNonQuery(); int theCount = (int)parameterTheCount.Value; At which point I was hoping the count would be in the parameter parameterTheCount that I could readily access. I keep getting the error ora-01036 which http://ora-01036.ora-code.com tells me to check my binding in the sql statement. Am I messing something up in the SQL statement? Am I missing something simple elsewhere? I could just use command.ExecuteScaler() as I am only getting one item, and am probably going to end up using that, but at this point, curiosity has got the better of me. What if I had two parameters I wanted back from my query (ie: select max(ColA), min(ColB) into :max, :min.....) Thanks..

• Dynamically created iframe not working on Safari

  - by mhammout

  I have a weird problem and I find no answer on google... I dynamically create and fullfil an iframe with jquery on a page. It works fine withFF and IE, but not with Safari. The iframe is created but empty (the message "greetings from the iframe !" is missing). Here is a piece of code to illustrate it : <!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" xml:lang="fr-fr" lang="fr-fr" > <head> <title>iframe</title> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <script type="text/javascript"> $(document).ready(function() { var jFrame = $('<iframe id="myiframe" name="myiframe">'); jFrame.css({'height':'40px','width':'200px'}).appendTo($('#container')); $('#myiframe').load(function() { jFrame.contents().find("body").html('greetings from the iframe !'); }); }); </script> </head> <body> <div id="container"></div> </body> </html> I really wonder why the iframe stays empty with Safari. It seems like if "contents()" was not well interpreted... Any idea ?

• Help write regex that will surround certain text with <strong> tags, only if the <strong> tag isn't

  - by sahil

  I have several posts on a website; all these posts are chat conversations of this type: AD: Hey! BC: What's up? AD: Nothing BC: Okay They're marked up as simple paragraphs surrounded by <p> tags. Using the javascript replace function, I want all instances of "AD" in the beginning of a conversation (ie, all instances of "AD" at the starting of a line followed by a ":") to be surrounded by <strong> tags, but only if the instance isn't already surrounded by a <strong> tag. What regex should I use to accomplish this? Am I trying to do what this advises against? The code I'm using is like this: var posts = document.getElementsByClassName('entry-content'); for (var i = 0; i < posts.length; i++) { posts[i].innerHTML = posts[i].innerHTML.replace(/some regex here/, 'replaced content here'); }

• Thread safe lazy contruction of a singleton in C++

  - by pauldoo

  Is there a way to implement a singleton object in C++ that is: Lazily constructed in a thread safe manner (two threads might simultaneously be the first user of the singleton - it should still only be constructed once). Doesn't rely on static variables being constructed beforehand (so the singleton object is itself safe to use during the construction of static variables). (I don't know my C++ well enough, but is it the case that integral and constant static variables are initialized before any code is executed (ie, even before static constructors are executed - their values may already be "initialized" in the program image)? If so - perhaps this can be exploited to implement a singleton mutex - which can in turn be used to guard the creation of the real singleton..) Excellent, it seems that I have a couple of good answers now (shame I can't mark 2 or 3 as being the answer). There appears to be two broad solutions: Use static initialisation (as opposed to dynamic initialisation) of a POD static varible, and implementing my own mutex with that using the builtin atomic instructions. This was the type of solution I was hinting at in my question, and I believe I knew already. Use some other library function like pthread_once or boost::call_once. These I certainly didn't know about - and am very grateful for the answers posted.

• How do ASP.NET MVC Routes work?

  - by Pure.Krome

  Hi folks, imagine i have the following route setup... public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( "Default", "{controller}/{action}/{id}", new { controller = "Home", action = "Index", id = "" } ); // Added custom route here! routes.MapRoute( "CatchAll", "{*catchall}," new { controller = "Error", action = "NotFound" } ); } nothing new - that's the default ASP.NET MVC1 RegisterRoutes method, with one custom route added. Now, if I goto the following url, i get a 404... http://whatever/Home/MissingActionMethod So there's no ActionMethod called MissingActionMethod in the HomeController. So, does this mean, if i goto the 1st route defined, above .. and fail to find an action .. do I then come back and try the second route? rinse-repeat? Or once i match a route, i then try and execute that route .. and if i fail (ie, find the action is missing) .. then .. bad luck? boomski? cheers!

• How to "escape" the JavaScript class keyword to specify a CSS class value.

  - by Robert Claypool

  C# allows a reserved word to be used as a property name via the ampersand. e.g. // In ASP.NET MVC, we use @class to define // the css class attribute for some HtmlHelper methods. var htmlObject = new { readonly = "readonly", @class = "ui-state-highlight" } I want to do the same in JavaScript. e.g. function makeGrid(grid, pager) { grid.jqGrid({ caption: 'Configurations', colNames: ['Id', 'Name'], colModel: [ { name: 'Id', index: 'Id' }, { name: 'Name', index: 'Name', editable: true, editoptions: { readonly: 'readonly', class: 'FormElement readonly' } }, ], pager: pager, url: 'www.example.com/app/configurations") %>', editurl: 'www.example.com/app/configurations/edit") %>' }).navGrid(pager, { edit: true, add: false, del: false, search: false }, {}, {}, {}); } Note class: 'FormElement readonly' is supposed to set the css class value on jqGrid's edit dialog, but IE errors out on the reserved word. Is there an escape character in JavaScript too? #class? @class? &class? Otherwise, how might I tell jqGrid to set the css class on the popup editor? Thank you.

• Is "Server not found" error related to Activclient?

  - by Kent

  Users are getting sporadic "Server not found" errors after idling in the browser. We have a HTTPS web application (Apache/Tomcat) using NSS for authentication on the server. The error occurs when a user opens the application and later lets it sit idle/untouched for 15 minutes. When they try to access the application they can get a "Server not found" error. Users use CAC cards with ActivClient software and our web application uses the certificates for authentication and authorization. We have been able to recreate the problem but have been unable to diagnose it. In recreating the problem the server is getting a series of "Unable to find the certificate or key necessary for authentication" errors in the NSS log associated with the browser error. These erros don't occur until the user tries to access the idle application. When the application is idle for 15 minutes the PIN is not requested yet the PIN Cache timeout in ActivClient is set at 15 minutes. All our server side timeout parameters are set to hours not minutes. IE 6 is our browser and NSS is using TLS. We have tried modifying "SetEnvIf User-Agent ".MSIE." ssl-unclean-shutdown" with no improvement. I understand that the PIN cache timeout and SSL session don't have a 1:1 relationship but the timing is suspicious. Can't find anything in the windows error logs that indicates a problem (security logs are not accessible to us). Any suggestions as to how to identify the cause of the problem would be appreciated.

• WHy am I unable to add text along with <%# Container.DataItem %> in repeater in user control

  - by Jamie Hartnoll

  I have a User Control which is dynamically placed by CodeBehind as follows: Dim myControl As Control = CType(Page.LoadControl("~/Controls/mainMenu.ascx"), Control) If InStr(Request.ServerVariables("url"), "/Login.aspx") <= 0 Then mainMenu.Controls.Add(myControl) End If As per an example from my previous question on here. Within this Control is a repeater which calls a database to generate values. My Repeater mark-up is as follows <asp:Repeater runat="server" ID="locationRepeater" OnItemDataBound="getQuestionCount"> <ItemTemplate> <p id='locationQuestions' title='<%# Container.DataItem %>' runat='server'></p> </ItemTemplate> </asp:Repeater> The example above works fine, but I want to be able to prepend text to <%# Container.DataItem %> in the title attribute of that <p to print to the browser like this is some text DATA_ITEM_OUTPUT When I try to do that though, it prints this is some text <%# Container.DataItem %> exactly like that, ie, turning <%# Container.DataItem %> into text, NOT the value from the repeater code. It was working fine before I made it into a dynamically inserted control, so I am thinking I might have something being generated in the wrong order, but given that it works without any prepended text, I am stumped to fix it! I'm new to .net and using vb.net, please could someone point me in the right direction?

• Unable to find reference to std library math function inside library

  - by Alex Marshall

  Hello, I've got several programs that use shared libraries. Those shared libraries in turn use various standard C libraries. ie Program A and Program B both use Shared Library S. Shared Library S uses std C math. I want to be able to statically link Shared Library S against the standard library, and then statically link Programs A and B against S so that I don't have to be dragging around the library files, because these programs are going to be running on an embedded system running BusyBox 0.61. However, when I try to statically link the programs against Shared Library S, I get an error message from GCC stating : ../lib/libgainscalecalc.a(gainscalecalc.): In function 'float2gs': [path to my C file].c:73: undefined reference to 'log' Can somebody please help me out ?

• dotNet Templated, Repeating, Databound ServerControl: Modifying underlying ServerControl data per te

  - by Campbeln

  I have a server control that wraps an underlying class which manages a number of indexes to track where it is in a dataset (ie: RenderedRecordCount, ErroredRecordCount, NewRecordCount, etc.). I've got the server control rendering great, but OnDataBinding I'm having an issue as to seems to happen after CreateChildControls and before Render (both of which properly manage the iteration of the underlying indexes). While I'm somewhat familiar with the ASP.NET page lifecycle, this one seems to be beyond me at the moment. So... How do I hook into the iterative process OnDataBinding uses so I can manage the underlying indexes? Will I have to iterate over the ITemplates myself, managing the indexes as I go or is there an easier solution? [edit: Agh... writing the problem out is very cathartic... I'm thinking this is exactly what I will need to do...] Also... I implemented the iteration of the underlying indexes during CreateChildControls originally in the belief that was the proper place to hook in for events like OnDataBinding (thinking it was done as the controls were being .Add'd). Now it seems that this may actually be unnecessary. So I guess the secondary question is: What happens during CreateChildControls? Are the unadulterated (read: with various <%-tags in place) controls added to the .Controls collection without any other processing?

• JQuery function not working as expected

  - by Mike

  I've written a little function to position a logo midway between the left hand side of the browser window and the (centered) navigation menu. The menu items are populated from a database, with the first item given the id item0. function positionLogo(){ var $menuleft=0; var $element=document.getElementById('item0'); if ($element.offsetParent) { do { $menuleft+=$element.offsetLeft; } while ($element=$element.offsetParent); } var $logoleft=($menuleft/2)-130; // As logo is 260px wide if ($logoleft<0) { $logoleft=0; } $('#logo').css('left',$logoleft); } $(document).ready(function(){ positionLogo(); }); $(window).resize(function(){ positionLogo(); }); This works fine when the window is resized, but when it first runs when the page is loaded, the position it sets is about 20px too far right (ie $logoleft is 20 more than it should be). As soon as the page is resized it jumps into the correct position. Haven't got it live anywhere at the moment but does anyone have any ideas? Thanks!

• Visual Studio 2008 Web Project problem with PNG files

  - by NoCarrier

  I've added a PNG file to a directory in my VS2k8 webforms project, and when I run the app, it refuses to render my image - it even knows the dimensions but renders a box with a red X. Oddly enough, if I double click the PNG file within VS2k8, it opens up in the IDE and displays fine (but only within the IDE). Does anyone have any clues? The path is correct.. I just have a basic default.aspx page with this in the body <img src="img/logo.png" /> if i navigate to img/logo.png in the browser, it shows a box with the same dimensions as my image, but a red x. Its finding the image, just not rendering it. It's showing up in IE running under the vs2k8 web server (localhost:5512/default.aspx) I've dropped a JPG in the same directory, and it shows up just fine. I'm not sure what type of PNG it is, but here is the kicker.... If i make an HTML file that references that image, copy both this HTML file and PNG file to my webserver (or just double click on the HTML page), it comes up JUST FINE. Its leading me to believe that the Visual Studio web server may not recognize PNG files (at least this one) properly?

• How do I simulate the usage of a sequence of web pages?

  - by Rory Becker

  I have a simple sequence of web pages written in ASP.Net 3.5 SP1. Page1 - A Logon Form.... txtUsername, txtPassword and cmdLogon Page2 - A Menu (created using DevExpress ASP.Net controls) Page3 - The page redirected to by the server in the event that the user picks the right menu option in Page2 I would like to create a threaded program to simulate many users trying to use this sequence of pages. I have managed to create a host Winforms app which Launches a new thread for each "User" I have further managed to work out the basics of WebRequest enough to perform a request which retrieves the Logon page itself. Dim Request As HttpWebRequest = TryCast(WebRequest.Create("http://MyURL/Logon.aspx"), HttpWebRequest) Dim Response As HttpWebResponse = TryCast(Request.GetResponse(), HttpWebResponse) Dim ResponseStream As StreamReader = New StreamReader(Response.GetResponseStream(), Encoding.GetEncoding(1252)) Dim HTMLResponse As String = ResponseStream.ReadToEnd() Response.Close() ResponseStream.Close() Next I need to simulate the user having entered information into the 2 TextBoxes and pressing logon.... I have a hunch this requires me to add the right sort of "PostData" to the request. before submitting. However I'm also concerned that "ViewState" may be an issue. Am I correct regarding the PostData? How do I add the postData to the request? Do I need to be concerned about Viewstate? Update: While I appreciate that Selenium or similar products are useful for acceptance testing , I find that they are rather clumsy for what amounts to load testing. I would prefer not to load 100 instances of Firefox or IE in order to simulate 100 users hitting my site. This was the reason I was hoping to take the ASPNet HttpWebRequest route.

• Table cell doesn't obey vertical-align CSS declaration when it contains a floated element

  - by mikez302

  I am trying to create a table, where each cell contains a big floated h1 on the left side, and a larger amount of small text to the right of the big text, vertically centered. However, the small text is showing up at the top of each cell, despite that it has a "vertical-align: middle" declaration. When I remove the big floated element, everything looks fine. I tested it in recent versions of IE, Firefox, and Safari, and this happened in every case. Why is this happening? Does anyone know of a way around it? Here is an example: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html><head> <meta http-equiv='Content-Type' content='text/html; charset=UTF-8'> <title>vertical-align test</title> <style type="text/css"> td { border: solid black 1px; vertical-align: middle; font-size: 12px} h1 { font-size: 40px; float: left} </style> </head> <body> <table> <tr> <td><h1>1</h1>The quick brown fox jumps over the lazy dog.</td> <td>The quick brown fox jumps over the lazy dog.</td> </tr> </table> </body></html> Notice that the small text in the first cell is at the top for some reason, but the text in the 2nd cell is vertically centered.

• jQuery UI Datepicker - Disable specific days

  - by Sam

  Is there any (easy) way to set the jQuery UI Datepicker to disallow selection of specific, predetermined days? I was able to get this approach working, however, it produces a null error which prevents it from displaying in IE. 'natDays[...].0' is null or not an object Thanks in advance! UPDATE: Might help if I included some code, right? Anyway, most of this was taken straight from the aforementioned thread: natDays = [ [7, 23], [7, 24], [8, 13], [8, 14], ]; function nationalDays(date) { for (i = 0; i < natDays.length; i++) { if (date.getMonth() == natDays[i][0] - 1 && date.getDate() == natDays[i][1]) { return [false, natDays[i][2] + '_day']; } } return [true, '']; } function noWeekendsOrHolidays(date) { var noWeekend = $.datepicker.noWeekends(date); if (noWeekend[0]) { return nationalDays(date); } else { return noWeekend; } } $(function() { $("#datepicker").datepicker({ inline: true, minDate: new Date(2009, 6, 6), maxDate: new Date(2009, 7, 14), numberOfMonths: 2, hideIfNoPrevNext: true, beforeShowDay: $.datepicker.noWeekends, altField: '#alternate', }); }); Thanks again!

• Append to a webpage in javascript

  What I want to do is that: a webpage with continuously updating content. (In my case is updating every 2s) New content is appended to the old one instead of overwriting the old one. Here is the code I have: var msg_list = new Array( "<message>Hello, Clare</message>", "<message>Hello,Lily</message>", "<message>Hello, Kevin</message>", "<message>Hello, Bill</message>" ); var number = 0; function send_msg() { document.write(number + " " + msg_list[number%4]+'<br/>'); number = number + 1; } var my_interval = setInterval('send_msg()', 2000); However, in both IE and Firefox, only one line is printed out, and the page will not be updated anymore. Interestingly in Chrome, the lines being printed out continuously, which is what I am looking for. I know that document.write() is called when the page is loaded according to this. So it's definitely not the way to update the webpage continuously. What will be the best way to achieve what I want to do? Totally newbie in Javascript. Thank you. Lily

• Old desktop programmer wants to create S+S project

  - by Craig

  I have an idea for a product that I want to be web-based. But because I live in Brasil, the internet is not always available so there needs to be a desktop component that is available for when the internet is down. Also, I have been a SQL programmer, a desktop application programmer using dBase, VB and Pascal, and I have created simple websites using HTML and website creation tools, such as Frontpage. So from my research, I think I have the following options; PHP, Ruby on Rails, Python or .NET for the programming side. MySQL for the DB. And Apache, or possibly IIS, for the webserver. I will probably start with a local ISP provider for the cloud servce. But then maybe move to something more "robust" and universal in the future, ie. Amazon, or Azure, or something along that line. My question then is this. What would you recommend for something like this? I'm sure that I have not listed all of the possibilities, but the ones I have researched and thought of. Thanks everyone, Craig

• Link doesnt work in FF

  - by venom

  Here is the link: <a href="javascript://" onClick="print_gonder();"><img src="/images/print.gif" title="Gönder" border="0"></a> and its function print_gonder: function print_gonder() { var satirsayisi=document.list_basketww.row_count.value; var amnt=new Array(satirsayisi); var prc=new Array(satirsayisi); var kdv=new Array(satirsayisi); var kon=new Array(satirsayisi); var yap=new Array(satirsayisi); var ona=new Array(satirsayisi); var ode=new Array(satirsayisi); var tes=new Array(satirsayisi); for (i=0; i<satirsayisi; i++) { amnt[i]=eval("document.getElementById('amount" + (i+1) + "')").value; prc[i]=filterNum(eval("document.getElementById('price" + (i+1) + "')").value); kdv[i]=eval("document.getElementById('tax_dif" + (i+1) + "')").value; kon=eval("document.getElementById('konu')").value; yap=eval("document.getElementById('yapan')").value; ona=eval("document.getElementById('onay')").value; ode=eval("document.getElementById('odeme')").value; tes=eval("document.getElementById('teslim')").value; } windowopen('<cfoutput>#request.self#?fuseaction=objects2.popup_sale_propose&print=true#page_code#&amnt='+amnt+'&prc='+prc+'&kdv='+kdv+'&konu='+kon+'&yapan='+yap+'&onay='+ona+'&odeme='+ode+'&teslim='+tes+'</cfoutput>','page'); } The problem is that this link doesnt work in FF but work in IE, but if i change the function into something like this: <a href="javascript://" onClick="<cfoutput>windowopen('#request.self#?fuseaction=objects2.popup_sale_propose&print=true#page_code#','page')</cfoutput"><img src="/images/print.gif" title="Gönder" border="0"></a> it perfectly works in all the browsers.. i think that the problem is in defining the values of the functions, the FF just doesnt understand them... btw, the system is Workcube and it uses the Cold Fusion.
