  • WPF ToolBar Separator shrinks to nothing when inside a StackPanel

    - by qntmfred
    Given the very simple wpf app <Window x:Class="Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="800"> <Grid> <ToolBar Height="50" > <MenuItem Header="Test1" /> <MenuItem Header="Test2" /> <StackPanel Orientation="Horizontal"> <Separator /> <MenuItem Header="Test3" /> <MenuItem Header="Test4" /> <MenuItem Header="Test5" /> </StackPanel> </ToolBar> </Grid> </Window> The Separator element shrinks to nothing. If I put the Separator just before the StackPanel begins, it will show up. Why does this happen? Is there a style setting that can be applied somewhere to avoid this?

  • jquery lightbox multiple items to look like mac dashboard

    - by Don
    Hope the title says it all... I'm wondering if it's possible in any existing lightbox to pop up a look similar to the mac dashboard where multiple divs could be "on" in the front with the main webpage with a gray overlay. Basically something where a user clicks an icon on the main webpage to call, and then 4 separate content boxes are popped on top, but not in a window like a gallery. I'm thinking the top background used could be set to transparent and the individual items could be divs on the popped area, but before I reinvent the wheel, I thought I'd see if there's something like this that I just haven't found in my searches. UPDATE: 1/7/2011 I ended up using colorbox with a background behind my divs. It doesn't look like the mac with items having the bg behind them showing between them, but after talking to the designer I'm working with, that wasn't something they really needed anyhow. I think it MAY be possible changing some of the CSS though for the bg of the "popped" window. Colorbox seems to be pretty nice about making it clear what the CSS is doing and there are multiple example skins. Just my $0.02...

  • Event type property lost in IE-8

    - by Channel72
    I've noticed a strange Javascript error which only seems to happen on Internet Explorer 8. Basically, on IE-8 if you have an event handler function which captures the event object in a closure, the event "type" property seems to become invalidated from within the closure. Here's a simple code snippet which reproduces the error: <html> <head> <script type = "text/javascript"> function handleClickEvent(ev) { ev = (ev || window.event); alert(ev.type); window.setTimeout(function() { alert(ev.type); // Causes error on IE-8 }, 20); } function foo() { var query = document.getElementById("query"); query.onclick = handleClickEvent; } </script> </head> <body> <input id = "query" type = "submit"> <script type = "text/javascript"> foo(); </script> </body> </html> So basically, what happens here is that within the handleClickEvent function, we have the event object ev. We call alert(ev.type) and we see the event type is "click". So far, so good. But then when we capture the event object in a closure, and then call alert(ev.type) again from within the closure, now all of a sudden Internet Explorer 8 errors, saying "Member not found" because of the expression ev.type. It seems as though the type property of the event object is mysteriously gone after we capture the event object in a closure. I tested this code snippet on Firefox, Safari and Chrome, and none of them report an error condition. But in IE-8, the event object seems to become somehow invalidated after it's captured in the closure. Question: Why is this happening in IE-8, and is there any workaround?

  • javascript to select text from web page

    - by phil swenson
    I'm trying to write a bookmarklet that grabs any selected text on a web page and sends it to my website. It should (hopefully) work in Chrome, FFX, Safari, and IE. I did a search and found a function, but it doesn't appear to work. Here is the code: <html> <body> <div onClick=getSelText()>Click</div> <div>please select me</div> </body> <script language=javascript> function getSelText(){ var txt = 'nothing'; if (window.getSelection){ txt = "1" + window.getSelection(); } else if (document.getSelection) { txt = "2" + document.getSelection(); } else if (document.selection) { txt = "3" + document.selection.createRange().text; } else return; alert("selected text = " + txt); } </script> </html> when I select the text in the div "please select me" and hit the click div, I just get "selected text = 1" thanks

  • doubt in javascript name validation

    - by raja
    Hi: I am using the below validation for textbox which accepts only alphabets and maximum of 50 characters. I am passing the object directly in the parameter. The below case by giving the field name i.e "my_text" directly is working is working fine. But if i pass it in variable, that time it is not working(commented the if statement). Please help me. My requirement is each time when we enter the charater, the hardcode field name should not be used in the validation. <html><head> <script language=JavaScript> function check_length(my_form,fieldName) { alert(fieldName); // if (my_form.fieldName.value.length >= maxLen) { if (my_form.my_text.value.length >= maxLen) { var msg = "You have reached your maximum limit of characters allowed"; alert(msg); my_form.my_text.value = my_form.my_text.value.substring(0, maxLen); } else{ var keyCode = window.event.keyCode; if ((keyCode < 65 || keyCode > 90) && (keyCode < 97 || keyCode > 123) && keyCode != 32) { window.event.returnValue = false; alert("Enter only Alphabets"); } my_form.text_num.value = maxLen - my_form.my_text.value.length;} } </script> </head> <body> <form name=my_form method=post> <input type="text" onKeyPress=check_length(this.form,this.name); name=my_text rows=4 cols=30> <br> <input size=1 value=50 name=text_num> Characters Left </form> </body> </html>

  • How to keep the CPU usage down while running an SDL program?

    - by budwiser
    I've done a very basic window with SDL and want to keep it running until I press the X on window. #include "SDL.h" const int SCREEN_WIDTH = 640; const int SCREEN_HEIGHT = 480; int main(int argc, char **argv) { SDL_Init( SDL_INIT_VIDEO ); SDL_Surface* screen = SDL_SetVideoMode( SCREEN_WIDTH, SCREEN_HEIGHT, 0, SDL_HWSURFACE | SDL_DOUBLEBUF ); SDL_WM_SetCaption( "SDL Test", 0 ); SDL_Event event; bool quit = false; while (quit != false) { if (SDL_PollEvent(&event)) { if (event.type == SDL_QUIT) { quit = true; } } SDL_Delay(80); } SDL_Quit(); return 0; } I tried adding SDL_Delay() at the end of the while-clause and it worked quite well. However, 80 ms seemed to be the highest value I could use to keep the program running smoothly and even then the CPU usage is about 15-20%. Is this the best way to do this and do I have to just live with the fact that it eats this much CPU already on this point?

  • Creating a dynamic two-column iOS spinning wheel with HTML/Javascript

    - by JSW189
    I am trying to create a dynamic two-column spinning wheel for iOS Safari using this HTML/Javascript wheel. However, I am having trouble getting the value of the first column to change the results of the second column. I have tried using an if statement to get the value of the first variable (var beverage) and add the value of the second column correspondingly. Does anybody know what I am doing wrong/if there is a better approach? function openBirthDate() { var beverage = { 1:'Coffee', 2:'Soda' }; //THIS IS WHERE I'M HAVING TROUBLE var results = SpinningWheel.getSelectedValues(); if (results.values === 1) { var company = { 1:'Starbucks', 2:'Dunkin Donuts' }; } else { var company = { 1:'Coke', 2:'Pepsi' }; } var size = { 1:'Tall', 2:'Grande', 3:'Venti' }; SpinningWheel.addSlot(type, '', 1); SpinningWheel.addSlot(company, '', 1); SpinningWheel.addSlot(size, '', 1); SpinningWheel.setCancelAction(cancel); SpinningWheel.setDoneAction(done); SpinningWheel.open(); } function done() { var results = SpinningWheel.getSelectedValues(); document.getElementById('result').innerHTML = 'values: ' + results.values.join(' ') + '<br />keys: ' + results.keys.join(', '); } function cancel() { document.getElementById('result').innerHTML = 'cancelled!'; } window.addEventListener('load', function(){ setTimeout(function(){ window.scrollTo(0,0); }, 100); }, true);

  • Thread Management Object

    - by Gusdor
    I feel rather foolish as this is just a short question. I was reading about a bunch of thread management helper classes in .net, specifically one that aids the storage of threads to help a service manager object automatically invoke delegates onto the subscribing thread. I'm pretty sure it had something to do with creating dispatchers. Totally forgotten the name, can't find it :( Anyone know what I'm talking about?

  • Should I thread this?

    - by Psytronic
    I've got a "Loading Progress" WPF form which I instantiate when I start loading some results into my Main Window, and every time a result is loaded I want the progress bar to fill up by x amount (Based on the amount of results I'm loading). However what happens is that the Progress bar in the window stays blank the entire time, until the results have finished loading, then it will just display the full progress bar. Does this need threading to work properly? Or is it just to do with the way I'm trying to get it to work? //code snippet LoadingProgress lp = new LoadingProgress(feedCount); lp.Show(); foreach (FeedConfigGroup feed in _Feeds) { feed.insertFeeds(lp); } //part of insertFeeds(LoadingProgress lbBox) foreach (Feeds fd in _FeedSource) { lpBox.setText(fd.getName); XmlDocument feedResults = new XmlDocument(); feedResults.PreserveWhitespace = false; try { feedResults.Load(wc.OpenRead(fd.getURL)); } catch (WebException) { lpBox.addError(fd.getName); } foreach (XmlNode item in feedResults.SelectNodes("/rss/channel/item")) { //code for processing the nodes... } lpBox.progressIncrease(); } If more code is needed let me know.

  • Is it worth the time to switch from AjaxControlToolkit to jQuery?

    - by Matthew Jones
    I keep hearing all these things about how awesome jQuery is and how the AjaxControlToolkit sucks. Unfortunately, I only heard about this after I built my entire WebForms site using the toolkit. Now I am considering switching, if not entirely, mostly to jQuery. This is partially for the experience (having never coded in Javascript or used any frameworks) and partially because I think I have more control over jQuery. There is no pressing need to switch, but I'm considering doing it anyway. Is it worth tackling the learning curve for jQuery just to get the experience, of should I leave my working site well enough alone?

  • How can I integrate Octopress into my Rails app?

    - by BeachRunnerFred
    I'm diving into web development and I built my personal website using Ruby on Rails 3.1 and I'd like to add a blog to it. Octopress sounds really awesome, and it's written in Ruby, but I can't find a single resource online that discusses integrating Octopress into a Rails app. I know that's not what it was designed for, but I'm amazed there's no discussion on it considering the popularity of these two technologies. The only resources I can find are discussions on using Octopress to create a stand-alone blog website. How can I integrate Octopress into my existing Rails 3.1 app? Can I set it up as a stand-alone website and integrate it as a sub-domain? Other suggestions? Thanks so much in advance for your wisdom!

  • javascript ajax help

    - by ngreenwood6
    I have the following code. var d3_ad = 1; function displayD3Ad(){ var query_string = '?d3_ad='+d3_ad; query_string += '&location='+escape(location); //document.write('<iframe src="index.php'+query_string+'"></iframe>'); var data = httpRequest('http://localhost/test/index.php','GET',query_string); document.write(data); } function httpRequest(strURL,type,query) { var request = false; if (window.XMLHttpRequest) {// Mozilla/Safari request = new XMLHttpRequest(); } else if (window.ActiveXObject) { //Internet Explorer request= new ActiveXObject("Microsoft.XMLHTTP"); } request.open(type, strURL + query, true); request.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded'); request.onreadystatechange = function() { if (request.readyState == 4) { return request.responseText; } } request.send(null); } displayD3Ad(); now when it writes out the data it is saying undefined. It seems like it isnt returning the data. I looked in firebug and it completes and shows the response that shoudl be there. Any help is appreciated. I just need to set the data variable so that I can use it later on.

  • What should go in each MVVM triad?

    - by Harry
    OK, let's say I am creating a program that will list users contacts in a ListBox on the left side of the screen. When a user clicks on the contact, a bunch of messages or whatever appears in the main part of the window. Now my question is: how should the MVVM triads look? I have two models: Contact, and Message. The Contact model contains a list of Message models. Each ViewModel object will contain a single corresponding Model, right? And what about the Views? I have a "MainView" that is the main window, that will have things like the menu, toolbar etc. Do I put the ListBox in the MainView? My confusion is with what to put where; for example, what should the ContactView contain? Just a single instance of a contact? So the DataTemplate, ControlTemplate, context menus, styles etc for that single contact, and then just have a ListBox of them in the MainView...? Thanks.

  • ContentPresenter within ControlTemplate cannot change attached dependency property

    - by happyclicker
    Why does the following simplified code not set the font-size of the TextBlock to 50? <Window.Resources> <ControlTemplate TargetType="ContentControl" x:Key="Test"> <ContentPresenter TextBlock.FontSize="50" /> </ControlTemplate> </Window.Resources> <Grid> <ContentControl Template="{StaticResource Test}"> <TextBlock>Test should be rendered big</TextBlock> </ContentControl> </Grid> If I change the value of the FontSize property, visual studio shows me the text in the size I want. After compiling or executing the app, the size of the textblock is always reset to its default size. I have also tested various versions with styles and embedded resources but I end always in the situation that I cannot set attached dp's from within a ControlTemplate that contains a ContentPresenter. Is this by design?

  • XAML get new width and height for Canvas

    - by Jack Navarro
    I have searched through many times but have not seen this before. Probably really simple question but can't wrap my head around it. Wrote a VSTO add-in for Excel that draws a Grid dynamically. Then launches a new window and replaces the contents of the Canvas with the generated Grid. The problem is with printing. When I call the print procedure the canvas.height and canvas.width returned is the old value prior to replacing it with the grid. Sample: string="<Grid Name=\"CanvasGrid\" xmlns=\"http://schemas.microsoft.com/winfx/2006/xaml/presentation\">..Lots of stuff..</Grid>"; // Launch new window and replace the Canvas element WpfUserControl newWindow = new WpfUserControl(); newWindow.Show(); //To test MessageBox.Show(myCanvas.ActualWidth.ToString()); //return 894 Grid testGrid = myCanvas.FindName("CanvasGrid") as Grid; MessageBox.Show("Grid " + testGrid.ActualWidth.ToString()); //return 234 StringReader stringReader = new StringReader(LssAllcChrt); XmlReader xmlReader = XmlReader.Create(stringReader); Canvas myCanvas = newWindow.FindName("GrphCnvs") as Canvas; myCanvas.Children.Clear(); myCanvas.Children.Add((UIElement)XamlReader.Load(xmlReader)); //To test MessageBox.Show(myCanvas.ActualWidth.ToString()); //return 894 but should be much larger the Grid spans all three of my screens Grid testGrid = myCanvas.FindName("CanvasGrid") as Grid; MessageBox.Show("Grid " + testGrid.ActualWidth.ToString()); //return 234 but should be much larger the Grid spans all three of my screens //Run code from WpfUserControl.cs after it loads from button click Grid testGrid = canvas.FindName("CanvasGrid") as Grid; MessageBox.Show("Grid " + testGrid.ActualWidth.ToString()); //return 234 but should be much larger the Grid spans all three of my screens So basically I have no way of telling what my new width and height are.

  • Problems with Backbone.Model callback and THIS

    - by Rev. Samuel
    I'm building a simple weather widget. The current weather conditions are read out of the National Weather Service xml file and then I want to parse and store the relevant data in the model but the callback for the $.ajax won't connect (the way I'm doing it). var Weather = Backbone.Model.extend({ initialize: function(){ _.bindAll( this, 'update', 'startLoop', 'stopLoop' ); this.startLoop(); }, startLoop: function(){ this.update(); this.interval = window.setInterval( _.bind( this.update, this ), 1000 * 60 * 60 ); }, stopLoop: function(){ this.interval = window.clearInterval( this.interval ); }, store: function( data ){ this.set({ icon : $( data ).find( 'icon_url_name' ).text() }); }, update: function(){ $.ajax({ type: 'GET', url: 'xml/KROC.xml', datatype: 'xml' }) .done( function( data ) { var that = this; that.store( $( data ).find( 'current_observation' )[ 0 ] ); }); } }); var weather = new Weather(); The data is read correctly but I can't get the done function of the call back to call the store function. (I would be happy if the "done" would just parse and then do "this.set". Thanks in advance for your help.

  • Ajax div can't access address bar variable

    - by Elaine Adams
    Can someone please advise me on how my Ajax div can get an address bar variable. The usual way just doesn't work. My address bar currently looks like this: http://localhost/social3/browse/?locationName=Cambridge Usually, I would use a little php and do this: $searchResult = $_POST['locationName']; echo $searchResult; But because I'm in an Ajax div, I can't seem to get to the variable. Do I need to add some JavaScript wizardry to my Ajax coding? (I have little knowledge of this) My Ajax: <script> window.onload = function () { var everyone = document.getElementById('everyone'), searching = document.getElementById('searching'), searchingSubmit = document.getElementById('searchingSubmit'); everyone.onclick = function() { loadXMLDoc('indexEveryone'); everyone.className = 'filterOptionActive'; searching.className = 'filterOption'; } searching.onclick = function() { loadXMLDoc('indexSearching'); searching.className = 'filterOptionActive'; everyone.className = 'filterOption'; } searchingSubmit.onclick = function() { loadXMLDoc('indexSearchingSubmit'); } function loadXMLDoc(pageName) { var xmlhttp; if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { document.getElementById("leftCont").innerHTML=xmlhttp.responseText; } } function get_query(){ var url = location.href; var qs = url.substring(url.indexOf('?') + 1).split('&'); for(var i = 0, result = {}; i < qs.length; i++){ qs[i] = qs[i].split('='); result[qs[i][0]] = decodeURIComponent(qs[i][1]); } return result; } xmlhttp.open("GET","../browse/" + pageName + ".php?user=" + get_query()['user'],true); xmlhttp.send(); } } </script> <!-- ends ajax script -->
