• visual c# 2008 database application examples

  - by Omar

  hi, i just have a few weeks programming with vc# (2008) and i'm trying to build an application (winforms) and i have the following problem... i need my application to work with and without connection to the mssql database, this sounds like piece of cake for our friend DataSet right? i can persist the data as XML or binary until i can reach the database and the DataSet will magically sync; all without bothering the user. The problem is... the few books i have read just mention that logic like a fairy tale but dont give any practical example of how to do it, can you point me to one example/demo/whatever i can read or download of an application with (equal or) similar logic?

• nivo slider and drop down menu doesnt work in IE

  - by venom

  Does anyone has any idea why drop down menu in IE disappear under nivo slider? tried to play with z-index, didn't help, i also know that drop down menus dissappear under flash content, but this is not the case(wmode=transparent) as far as i know the nivo slider uses just jquery, no flash. here is the html: <table> <tr height="50"><td colspan="2" align="right" class="bottom_menu"> <ul id="nav" class="dropdown dropdown-horizontal" > <li><a href="/index.cfm?fuseaction=home.logout" class="dir" style="border:0 !important;" >Çikis</a></li> <li><a href="/index.cfm?fuseaction=objects2.list_basket" class="dir">Sepetim</a></li> <li><a href="/index.cfm?fuseaction=objects2.me" class="dir">Sirketim</a> <ul> <li><a href="/index.cfm?fuseaction=objects2.list_opportunities">Firsatlar</a></li> <li><a href="/index.cfm?fuseaction=objects2.form_add_partner">Sirkete Kullanici Ekle</a></li> <li><a href="/index.cfm?fuseaction=objects2.form_upd_my_company">Kullanici Yönetimi</a></li> <li><a href="/index.cfm?fuseaction=objects2.list_analyses">Analizler</a></li> <li><a href="/index.cfm?fuseaction=objects2.list_extre">Hesap Ekstresi</a></li> <li><a href="/index.cfm?fuseaction=objects2.popup_add_online_pos" target="_blank">Sanal Pos</a></li> </ul> </li> </ul> </td></tr> </table> <div id="banner"> <img src="/documents/templates/projedepo/l_top.gif" style="z-index:1;position:absolute; left:0; top:0;" width="24px" height="24px" border="0" /> <img src="/documents/templates/projedepo/r_top.gif" style="z-index:1;position:absolute; right:0; top:0;" width="24px" height="24px" border="0" /> <img src="/documents/templates/projedepo/l_bottom.gif" style="z-index:1;position:absolute; left:0; bottom:0;" width="24px" height="24px" border="0" /> <img src="/documents/templates/projedepo/r_bottom.gif" style="z-index:1;position:absolute; right:0; bottom:0;" width="24px" height="24px" border="0" /> <div class="banner_img"> <link rel="stylesheet" href="/documents/templates/projedepo/banner/nivo-slider.css" type="text/css" media="screen" /> <link rel="stylesheet" href="/documents/templates/projedepo/banner/style.css" type="text/css" media="screen" /> <div id="slider" class="nivoSlider"> <img title="#1" src="/documents/templates/projedepo/banner/canon.jpg" alt="" /> <img title="#2" src="/documents/templates/projedepo/banner/indigovision.jpg" alt="" /> </div> <div id="1" class="nivo-html-caption"> <a href="/index.cfm?fuseaction=objects2.detail_product&product_id=612&stock_id=612"><img src="/documents/templates/projedepo/banner/daha_fazlasi.jpg" border="0" /></a> </div> <div id="2" class="nivo-html-caption"> <a href="/index.cfm?fuseaction=objects2.detail_product&product_id=630&stock_id=630"><img src="/documents/templates/projedepo/banner/daha_fazlasi.jpg" border="0" /></a> </div> <script type="text/javascript" src="/JS/jquery.nivo.slider.pack.js"></script> <script type="text/javascript"> $(window).load(function() { $('#slider').nivoSlider({ effect:'random', //Specify sets like: 'fold,fade,sliceDown' slices:15, animSpeed:1000, //Slide transition speed pauseTime:10000, startSlide:0, //Set starting Slide (0 index) directionNav:true, //Next & Prev directionNavHide:true, //Only show on hover controlNav:true, //1,2,3... controlNavThumbs:false, //Use thumbnails for Control Nav controlNavThumbsFromRel:false, //Use image rel for thumbs controlNavThumbsSearch: '.jpg', //Replace this with... controlNavThumbsReplace: '_thumb.jpg', //...this in thumb Image src keyboardNav:true, //Use left & right arrows pauseOnHover:true, //Stop animation while hovering manualAdvance:false, //Force manual transitions captionOpacity:1.0, //Universal caption opacity beforeChange: function(){}, afterChange: function(){}, slideshowEnd: function(){}, //Triggers after all slides have been shown lastSlide: function(){}, //Triggers when last slide is shown afterLoad: function(){} //Triggers when slider has loaded }); }); </script> </div> </div> Here is css for dropdown menu: http://www.micae.com/documents/templates/projedepo/default.css http://www.micae.com/documents/templates/projedepo/default.advanced.css http://www.micae.com/documents/templates/projedepo/dropdown.css and for nivo slider: http://www.micae.com/documents/templates/projedepo/banner/style.css http://www.micae.com/documents/templates/projedepo/banner/nivo-slider.css and for banner divs: #banner { position:relative; width:980px; height:435px; background:#fff; margin-bottom:20px; margin-top:-1px; color:#000; z-index:60; } .banner_img { padding:8px;position:absolute;z-index:2; } and the javascript by default, jquery and nivo slider http://www.micae.com/JS/jquery.nivo.slider.pack.js

• Making a window pop in and out of the edge of the screen

  - by Brad

  I'm trying to re-write an application I have for Windows in Objective-C for my Mac, and I want to be able to do something like Mac's hot corners. If I move my mouse to the left side of the screen it will make a window visible, if I move it outside of the window location the window will hide again. (window would be pushed up to the left side of screen). Does anyone know where I can find some demo code (or reference) on how to do this, or at least how to tell where the mouse is at, even if the current application is not on top. (not sure how to word this, too used to Windows world). Thank you -Brad

• Actionscript 3 3D sizing problem

  - by Simon

  I have an application where I can have an image moving towards the eye. When the image enlarged, I would like to have it resized as 635 px where initial size was 220 px. I have the image with starting position as 0 in z axis. I am wanting to calculate the distance from starting position to the resized image. I have already calculate the distance by hand but when I tried to put it on flash the result is not what i wanted. I am sure that the value I calculated was correct. I know it may be hard to understand my problem. Please help.

Platform: windows XP UPDATE AGAIN This is indeed a gtk bug,which is un-fixable.

• How do you access byte level information in JavaScript?

  - by JustSmith

  The generally accepted answer is that you can't. However there is mounting evidence that this is not true based on the existence of projects that read in types of data that are not basic HTML types. Some projects that do this are the JavaScript version of ProtoBuf and Smokescreen. Smokescreen is a flash interpreter written in JS so if it is not possible to get at the bytes directly how are these projects working around this? The source to Smokescreen can be found here. I have looked it over but with JS not being my primary language right now the solution eludes me.

• How to update user info with restful_authentication plugin in Rails?

  - by benoror

  Hi people, I want to give the users to change their account info with restful_authentication plugin in rails. I added this two methods to my controller: def edit @user = User.find(params[:id]) end def update @user = User.find(params[:id]) # Only update password when necessary params[:user].delete(:password) if pàrams[:user][:password].blank? respond_to do |format| if @user.update_attributes(params[:user]) flash[:notice] = 'User was successfully updated.' format.html { redirect_to(@user) } format.xml { head :ok } else format.html { render :action => "edit" } format.xml { render :xml => @user.errors, :status => :unprocessable_entity } end end end Also, I copied new.html.erb to edit.html.erb. Considering that resources are already defined in routes.rb I was expecting it to work easily, bute somehow when I click the save button it calls the create method, instead of update, using a POST http request. Any ideas?

• IE error with jquery counter plugin

  - by Mankey

  I've implemented a jquery counter script (count up from say 50 to 100 with different increments) that I found from this question: jQuery counter to count up to a target number The scripts works great except for in Internet Explorer 8 (and possibly other IE versions?). Here's an error message from IE with the URL to the creator of the script's demo. Message: 'undefined' is null or not an object Line: 32 Char: 17 Code: 0 URI: http://www.ulmanen.fi/stuff/counter.php I'm just wondering if anyone know how this can be fixed. I'm guessing it has to do with el.html() not finding any data but I can't really figure this out. Thanks for any help ^^ I would reply to that post if I could but I can't seem to find any way of doing so (I'm new to stackoverflow, I think I lack privileges).

• How do I execute a page-defined JavaScript function from a Firefox extension?

  - by yuku

  Hi, I'm creating a Firefox extension for demo purposes. I to call a specific JavaScript function in the document from the extension. I wrote this in my HTML document (not inside extension, but a page that is loaded by Firefox): document.funcToBeCalled = function() { // function body }; Then, the extension will run this on some event: var document = Application.activeWindow.activeTab.document; document.funcToBeCalled(); However it raises an error saying that funcToBeCalled is not defined. Note: I could get an element on the document by calling document.getElementById(id);

• How can should I set up Flex 3 projects that reference common controls?

  - by Amy

  I'm not a flash developer, I'm having issues figuring out how I should set up these two projects that I have in Flex Builder. I've already created projA which has a .mxml that references several custom controls & skins from com.xxx.controls within projA I now have to build projB which also has a .mxml that will create a different .swf. I want to use some of the same controls from projA I currently build projA through the command line and nant and will need to do the same for projB. Should I create a new project to move all of the common controls into? How do I then use this library project in both the projects & compile via command? Thanks!

• Screen scraping an application window and interacting with the mouse and keyboard

  - by ccook

  The other day I found myself addicted to a flash game and frustrated by the thing at the same time. In a moment of frustration with the game I thought I would make a 'bot' to beat it for me. Well, I really wouldn't, but it made me realize: I don't know how to interact with another application in a way to do this. Which brings me to the question, how would one take screenshots of another running application and interact with it with the keyboard and mouse. Ideally the solution would be in a managed language like c#. When doing the background reading the net was drowning with articles on scrapping HTML. There were not many articles on actually screen scrapping an application. Diverse answers are appreciated as I’m really looking at surveying what’s out there.

• Element point map for html5 canvas element, need algorithm

  - by Artiom Chilaru

  I'm currently working on a pure html 5 canvas implementation of the "flying tag cloud sphere", which many of you have undoubtedly seen as a flash object in some pages. The tags are drawn fine, and the performance is satisfactory, but there's one thing in the canvas element that's kind of breaking this idea: you can't identify the objects that you've drawn on a canvas, as it's just a simple flat "image".. What I have to do in this case is catch the click event, and try to "guess" which element was clicked. So I have to have some kind of matrix, which stores a link to a tag object for each pixel on the canvas, AND I have to update this matrix on every redraw. Now this sounds incredibly inefficient, and before I even start trying to implement this, I want to ask the community - is there some "well known" algorithm that would help me in this case? Or maybe I'm just missing something, and the answer is right behind the corner? :)

• Flex RemoteObject Intermittently Failing to Invoke CFC

  - by Justin

  I have a Flex app that uses Flash Remoting and the RemoteObject to pull data from a ColdFusion CFC. About 75% of the time it works, but the other times I get a message using Charles (a debugging tool) that says faultString = "Unable to Invoke CFC". FaultCode = "Server.Processing". Here's my RemoteObject: The server set up on our web farm is to use load balancing. I'm not sure if this is causing the problem or not. Probably not, but it's a thought. Any help is appreciated!!

• Non laggy movement in Flex or WPF

  - by PaN1C_Showt1Me

  I'm trying to learn something about 2D games programming. For this purpose I've downloaded many samples developed in: Flex and Microsoft WPF. I've noticed that all the animations / moving objects are kind of non-smooth. I've seen a Flex example with double buffering which solved the image flickering, but it was laggy too. WPF example too. Just to mentioned, all examples were drawing on Canvas. I'm just curious, is it possible to have a wonderful non-laggy movement on the GUI in Flash or WPF ? (e.g. like a real game, coded in C++)

• Onclick starts gif animation and .mp3, how to sync across browsers

  - by user2958163

  So I am using a text-based jplayer (http://jplayer.org/latest/demo-04/) that I want to sync with a gif animation. Onclick the text link does two things -1. feed the jplayer an mp3 and 2. trigger an animation (via SwapImage). It is important for these two to start at the same time. Right now, this works perfectly in chrome/firefox but in IE and mobile browsers the audio lags considerably. I have tried with the audio preloaded (it is a small 40K mp3) and it makes no difference. I dont think its a bandwidth problem because the problem is the same on repeat clicks. Any pointers on how I can resolve this...

• WinForms / .Net interactive world map - how?

  - by FerretallicA

  In a CD collection program, I have each artist's country of origin stored in the main database and want to display a map of the world which: Colour-codes each country depending on the number of CDs by artists in that country Allows clicking on each country to filter a list of CDs to only ones by artists in that country This is a heavily simplified version of what I'm trying to do, but if I can at least get this far the rest should be easy enough to figure out. So far the closest thing I've found to what I'm trying to do is here: http://www.synergetechsolutions.com/blog/analytics-world-map-control Ideally I don't want to be embedding Flash in my program though, and the only other solutions I've found all involve SVG which I haven't managed to get working in practice outside of a web browser control (and I DEFINITELY don't want to be embedding a browser in the forms). Something in pure managed code and either GDI+ or WPF would be preferable. Are there any existing components that would get me started, or can anyone suggest how to approach it from scratch?

• How to detect default printer properties from browser?

  - by Annan

  Regardless of if this is a good idea or not, is it possible to detect printer attributes from the browser? The idea is that you want to print out a brochure that's selling something. Depending on different things such as if the printer is black&white/colour, high/low resolution, laser/inkjet, printing to a file, etc, you want to print out the page differently. For example you might choose different text colours or fonts, different image sizes, etc. My initial thoughts are: ActiveX, Flash, Java, Silverlight, browser plugins. Kudos if it's possible in javascript. I'm interested in all ways to do this, cross browser or not. Please no reasons about why this shouldn't be done ^_^

• Rails and jQuery - how do you get server-side validation errors to your view after an ajax request

  - by adam

  Ive searched this site but questions are usually regarding doing client-side validations or for different frameworks. I have a tasks list whose items can be edited inline. Upon submitting the inline edit form the item is updated all thanks to jQuery, ajax and rails. But I want to handle bad input from the user. HTML requests redisplay the view and errors are displayed thanks to rails helpers. But how do I insert that information after an ajax call? Heres my update method in my controller def update @task = Task.find(params[:id]) respond_to do |format| if @task.update_attributes(params[:task]) flash[:notice] = 'Task was successfully updated.' format.html { redirect_to(@task) } format.xml { head :ok } format.js else format.html { render :action => "edit" } format.xml { render :xml => @task.errors, :status => :unprocessable_entity } #format.js ...hmmm... either go to js.erb file or do stuff inline end end end

• Why does Printing from Javascript in Air happen out of order?

  - by Bob Bob

  I am trying to print from an Adobe Air App that embeds an AJAX app. The print function looks like this: function printPage() { asyncSetupForPrint(printCallback); } function asyncSetupForPrint(printCallback) { synchronousMethods(); if (printCallback) printCallback(); } function printCallback() { var pjob = new window.runtime.flash.printing.PrintJob; var psprite = window.htmlLoader; pjob.start(); // etc... } However the print dialog is coming up before the synchronous methods have been executed. Is the AIR JS runtime optimizing something? And if so, is there any way to stop it doing that? (The setup function is doing things like changing the resolution to huge*huge so that the print out looks ok.)

• Easiest, free way to start with Flex?

  - by Jon

  I'm interested in getting started with Flex, as I've wanted to work with flash for quite awhile but have never liked the designer-oriented way of programming. I've heard flex can be used for free, and is programmer friendly, but I'm having some issues... I can't find any good sites with flex resources. I'm used to PHP, so maybe I'm spoiled with a full manual, comments and tutorials, but I can't even find a decent tutorial site. So, what are some good flex starts to get started, and what's a good, free IDE to program with?

• CSS: Why won't this box get wider?

  - by Jason

  I just need a sanity check here... DEMO Basically, I can't figure out how to get the box under the link to get wider as more content is added. It seems fixed to the width of the parent div (or the width of, say, the longest element like the select or a really long word with no spaces), despite being absolutely positioned. I use this trick all the time with ul and li but it doesn't make sense to use that in my situation, and for some crazy reason it just won't work with a div inside a div. I don't want to set a width (which, of course, works) because I don't always know what will be in this box. GRR Thanks :\

• Coffeeshop limits Internet connection to 30 minutes -- how does it recognize me if I delete my cooki

  - by Andrew

  I was connected to the Internet in a coffeeshop earlier today, but I was only allowed 30 minutes of access. I tried deleting my cookies after my time was up (though admittedly I didn't delete my Flash cookies -- would that have solved the problem?), but the connection still recognized that I'd already used 30 minutes, so I couldn't connect again. How did the connection recognize me still? The wireless was unprotected (no code or password), it just had a portal you had to pass through upon the initial connection. I'm not terribly familiar with web development or computer networks, so just trying to get a better idea of what's happening (and possibly to know what to do next time I use up my minutes =)).
