  • Dojox grid having problem with Contentpane

    - by ice
    the grid appears properly on template's first loading. But when you click the paging button to load flooders.php thru list_result1() only the paging buttons will appear. I already tested the flooders.php outside the template and it works properly. what seems to be the problem? and what are the tools that i can use to see if the javascript is loading properly because i think the error console of ff browser which i use to track errors won't give you that much info when you are working with contentpane. thanks! ice note: below are the codes... ** from contentpane js function list_result1(){ args=""; uri = "flooders.php" + args; dojo.xhrGet( { url: uri, handleAs: "text", timeout: 500, // Time in milliseconds load: function(response, ioArgs) { //alert(response); dojo.byId("flooders_table").innerHTML = response; return response; }, // The ERROR function will be called in an error case. error: function(response, ioArgs) { console.error("HTTP status code: ", ioArgs.xhr.status); return response; } }); //end of dojo.xhrGet } **flooders.php starts here*** @import "js/dojo-0.9.0/dojo/resources/dojo.css"; @import "js/dojo-0.9.0/dijit/themes/tundra/tundra.css"; @import "js/dojo-0.9.0/dijit/themes/tundra/tundra_rtl.css"; @import "css/ash.css"; @import "js/dojo-0.9.0/dojox/grid/resources/Grid.css"; @import "js/dojo-0.9.0/dojox/grid/resources/tundraGrid.css"; @import "js/dojo-0.9.0/dojo/resources/dojo.css"; @import "js/dojo-0.9.0/dijit/tests/css/dijitTests.css"; .dojoxGridRowEditing td { background-color: #F4FFF4; } .dojoxGrid input, .dojoxGrid select, .dojoxGrid textarea { margin: 0; padding: 0; border-style: none; width: 100%; font-size: 100%; font-family: inherit; } .dojoxGrid input { } .dojoxGrid select { } .dojoxGrid textarea { } #controls { padding: 0px 0; } #controls button { margin-left: 10px; } .myGrid { width: 550px; height: 230px; margin-left: 20px; /* border: 1px solid silver; */ } echo " // it has script heading here (function(){ // some sample data // global var 'data' data = { identifier: 'id', label: 'id', items: [] }; data_list = [ $banlist ]; var rows = $listnum ; var x=1; for(var i=0, l=data_list.length; i // global var 'test_store' test_store = new dojo.data.ItemFileWriteStore({data: data}); })(); // it has ending here "; ?   -- here's the javascript dojo.require("dijit.TitlePane"); dojo.require("dijit.dijit"); dojo.require("dojox.grid.DataGrid"); dojo.require("dojo.data.ItemFileWriteStore"); dojo.require("dojo.parser"); // scan page for widgets and instantiate them dojo.require("dijit.layout.LayoutContainer"); dojo.require("dijit.layout.AccordionContainer"); dojo.require("dijit.layout.ContentPane"); dojo.require("dijit.layout.TabContainer"); dojo.require("dijit.Editor"); dojo.require("dijit._editor.plugins.AlwaysShowToolbar"); dojo.require("dijit._editor.plugins.LinkDialog"); //this must be inlcuded below function() selectCell = { styles: 'text-align: center;', type: dojox.grid.cells.Select }; gridLayout = { defaultCell: { width: 5, styles: 'text-align: right;' }, rows: [ [ { name: 'Mark', width: 3, field: 'col1', editable: true, styles: 'text-align: center;', type: dojox.grid.cells.Bool }, { name: 'Id', width: 3, field: 'id' , editable: false }, { name: 'Username', field: 'col2', editable: false, styles: '', width: '70%' }, { name: 'Reason', field: 'col3', editable: false , styles: '', width: '100%' }, { name: 'Date Banned', field: 'col4', editable: false , styles: '', width: '70%' } ] ] };

  • jquery ui autocomplete positioning wrong

    - by mattRo55
    using jquery ui 1.8 trying autocomplete Everything works apart from that the ui-menu isn't positioned under my input element, but rather in the top left corner. Has anyone come across this problem? Here's my html: <div id="search"> <div id="searchFormWrapper"> <form method="post" name="searchForm" id="searchForm" action="/searchresults"> <label for="searchPhrase" id="searchFor"> Search for</label> <input name="searchPhrase" id="searchPhrase" type="text" /> <label for="searchScope" id="searchIn"> in</label> <select name="searchScope" id="searchScope"> <option value="">All Shops</option> ... </select> <input type="image" name="submitSearch" id="submitSearch" src="/images/buttons/search.gif" alt="Search ..." /> </form> <br class="clear" /> </div> </div> and here's my css: #search { width:100%; margin:0; padding:0; text-align:center; height:36px; line-height:36px; background:#666 url(/images/interface/info_bar_bg.gif) repeat-x top left; overflow:hidden; font-size:12px; } #searchFormWrapper { width:520px; height:36px; overflow:hidden; margin:auto; padding:0; } label#searchFor { display:block; float:left; width:80px; padding:0 5px 0 0; margin:0 0 0 0; text-align:right; } label#searchIn { display:block; float:left; width:20px; padding:0 5px 0 0; margin:0 0 0 0; text-align:right; } #searchPhrase { display:block; float:left; width:120px; margin:7px 0 0 0; padding:0; } #searchScope { display:block; float:left; width:120px; margin:7px 0 0 0; padding:0; } #submitSearch { display:block; float:left; margin:7px 0 0 10px; padding:0; } and here's my javascript: $(document).ready(function() { $("#searchPhrase").autocomplete( { source: "/search?json", minLength: 2 }); });

  • How to take the sanpshot of a IE webpage through a BHO (C#)

    - by Kapil
    Hi, I am trying to build an IE BHO in C# for taking the snapshot of a webpage loaded in the IE browser. Here is what I'm trying to do: public class ShowToolbarBHO : BandObjectLib.IObjectWithSite { IWebBrowser2 webBrowser = null; public void SetSite (Object site) { ....... if (site != null) { ...... webBrowser = (IWebBrowser2)site; ...... } } } Also, I p/invoke the following COM methods: [Guid("0000010D-0000-0000-C000-000000000046")] [InterfaceTypeAttribute(ComInterfaceType.InterfaceIsIUnknown)] [ComImportAttribute()] public interface IViewObject { void Draw([MarshalAs(UnmanagedType.U4)] int dwDrawAspect, int lindex, IntPtr pvAspect, [In] IntPtr ptd, IntPtr hdcTargetDev, IntPtr hdcDraw, [MarshalAs(UnmanagedType.LPStruct)] ref COMRECT lprcBounds, [In] IntPtr lprcWBounds, IntPtr pfnContinue, int dwContinue); int GetColorSet([MarshalAs(UnmanagedType.U4)] int dwDrawAspect, int lindex, IntPtr pvAspect, [In] IntPtr ptd, IntPtr hicTargetDev, [Out] IntPtr ppColorSet); int Freeze([MarshalAs(UnmanagedType.U4)] int dwDrawAspect, int lindex, IntPtr pvAspect, out IntPtr pdwFreeze); int Unfreeze([MarshalAs(UnmanagedType.U4)] int dwFreeze); int SetAdvise([MarshalAs(UnmanagedType.U4)] int aspects, [MarshalAs(UnmanagedType.U4)] int advf, [MarshalAs(UnmanagedType.Interface)] IAdviseSink pAdvSink); void GetAdvise([MarshalAs(UnmanagedType.LPArray)] out int[] paspects, [MarshalAs(UnmanagedType.LPArray)] out int[] advf, [MarshalAs(UnmanagedType.LPArray)] out IAdviseSink[] pAdvSink); } [StructLayoutAttribute(LayoutKind.Sequential)] public class COMRECT { public int left; public int top; public int right; public int bottom; public COMRECT() { } public COMRECT(int left, int top, int right, int bottom) { this.left = left; this.top = top; this.right = right; this.bottom = bottom; } } [InterfaceTypeAttribute(ComInterfaceType.InterfaceIsIUnknown)] [ComVisibleAttribute(true)] [GuidAttribute("0000010F-0000-0000-C000-000000000046")] [ComImportAttribute()] public interface IAdviseSink { void OnDataChange([In]IntPtr pFormatetc, [In]IntPtr pStgmed); void OnViewChange([MarshalAs(UnmanagedType.U4)] int dwAspect, [MarshalAs(UnmanagedType.I4)] int lindex); void OnRename([MarshalAs(UnmanagedType.Interface)] object pmk); void OnSave(); void OnClose(); } Now When I take the snapshot: I make a call CaptureWebScreenImage((IHTMLDocument2) webBrowser.document); public static Image CaptureWebScreenImage(IHTMLDocument2 myDoc) { int heightsize = (int)getDocumentAttribute(myDoc, "scrollHeight"); int widthsize = (int)getDocumentAttribute(myDoc, "scrollWidth"); Bitmap finalImage = new Bitmap(widthsize, heightsize); Graphics gFinal = Graphics.FromImage(finalImage); COMRECT rect = new COMRECT(); rect.left = 0; rect.top = 0; rect.right = widthsize; rect.bottom = heightsize; IntPtr hDC = gFinal.GetHdc(); IViewObject vO = myDoc as IViewObject; vO.Draw(1, -1, (IntPtr)0, (IntPtr)0, (IntPtr)0, (IntPtr)hDC, ref rect, (IntPtr)0, (IntPtr)0, 0); gFinal.ReleaseHdc(); gFinal.Dispose(); return finalImage; } I am not getting the image of the webpage. Rather I am getting an image with black background. I am not sure if this is the right way of doing it, but I found over the web that IViewObject::Draw method is used for taking the image of a webpage in IE. I was earlier doing the image capture using the Native PrintWindow() method as mentioned in the following codeproject's page - http://www.codeproject.com/KB/graphics/IECapture.aspx But the image size is humongous! I was trying to see if I can reduce the size by using other techniques. It would be great if someone can point out the mistakes (I am sure there would be many) in my code above. Thanks, Kapil

  • How can I bind the nested viewmodels to properties of a control

    - by Robert
    I used Microsoft's Chart Control of the WPF toolkit to write my own chart control. I blogged about it here. My Chart control stacks the yaxes in the chart on top of each other. As you can read in the article this all works quite well. Now I want to create a viewmodel that controls the data and axes in the chart. So far I'm able to add axes to the chart and show them in the chart. But I have a problem when I try to add the lineseries because it has one DependentAxis and one InDependentAxis property. I don't know how to assign the proper xAxis and yAxis controls to it. Below you see part of the LineSeriesViewModel. It has a nested XAxisViewModel and YAxisViewModel property. public class LineSeriesViewModel : ViewModelBase, IChartComponent { XAxisViewModel _xAxis; public XAxisViewModel XAxis { get { return _xAxis; } set { _xAxis = value; RaisePropertyChanged(() => XAxis); } } //The YAxis Property look the same } The viewmodels all have their own datatemplate. The xaml code looks like this: <UserControl.Resources> <DataTemplate x:Key="xAxisTemplate" DataType="{x:Type l:YAxisViewModel}"> <chart:LinearAxis x:Name="yAxis" Orientation="Y" Location="Left" Minimum="0" Maximum="10" IsHitTestVisible="False" Width="50" /> </DataTemplate> <DataTemplate x:Key="yAxisTemplate" DataType="{x:Type l:XAxisViewModel}"> <chart:LinearAxis x:Name="xAxis" Orientation="X" Location="Bottom" Minimum="0" Maximum="100" IsHitTestVisible="False" Height="50" /> </DataTemplate> <DataTemplate DataType="{x:Type l:LineSeriesViewModel}"> <!--Binding doesn't work on the Dependent and IndependentAxis! --> <!--YAxis XAxis and Series are properties of the LineSeriesViewModel --> <l:FastLineSeries DependentAxis="{Binding Path=YAxis}" IndependentAxis="{Binding Path=XAxis}" ItemsSource="{Binding Path=Series}"/> </DataTemplate> <Style TargetType="ItemsControl"> <Setter Property="ItemsPanel"> <Setter.Value> <ItemsPanelTemplate> <!--My stacked chart control --> <l:StackedPanel x:Name="stackedPanel" Width="Auto" Height="Auto" Background="LightBlue"> </l:StackedPanel> </ItemsPanelTemplate> </Setter.Value> </Setter> </Style> </UserControl.Resources> <Grid HorizontalAlignment="Stretch" VerticalAlignment="Stretch" ClipToBounds="True"> <!-- View is an ObservableCollection of all axes and series--> <ItemsControl x:Name="chartItems" ItemsSource="{Binding Path=View}" Focusable="False"> </ItemsControl> </Grid> This code works quite well. When I add axes they get drawn. But the DependentAxis and InDependentAxis of the lineseries control stay null, so the series doesn't get drawn. How can I bind the nested viewmodels to the properties of a control?

  • Prevent ListBox from focusing but leave ListBoxItem(s) focusable (wpf)

    - by modosansreves
    Here is what happens: I have a listbox with items. Listbox has focus. Some item (say, 5th) is selected (has a blue background), but has no 'border'. When I press 'Down' key, the focus moves from ListBox to the first ListBoxItem. (What I want is to make 6th item selected, regardless of the 'border') When I navigate using 'Tab', the Listbox never receives the focus again. But when the collection is emptied and filled again, ListBox itself gets focus, pressing 'Down' moves the focus to the item. How to prevent ListBox from gaining focus? P.S. listBox1.SelectedItem is my own class, I don't know how to make ListBoxItem out of it to .Focus() it. EDIT: the code Xaml: <UserControl.Resources> <me:BooleanToVisibilityConverter x:Key="visibilityConverter"/> <me:BooleanToItalicsConverter x:Key="italicsConverter"/> </UserControl.Resources> <ListBox x:Name="lbItems"> <ListBox.ItemTemplate> <DataTemplate> <Grid> <ProgressBar HorizontalAlignment="Stretch" VerticalAlignment="Bottom" Visibility="{Binding Path=ShowProgress, Converter={StaticResource visibilityConverter}}" Maximum="1" Margin="4,0,0,0" Value="{Binding Progress}" /> <TextBlock Text="{Binding Path=VisualName}" FontStyle="{Binding Path=IsFinished, Converter={StaticResource italicsConverter}}" Margin="4" /> </Grid> </DataTemplate> </ListBox.ItemTemplate> <me:OuterItem Name="Regular Folder" IsFinished="True" Exists="True" IsFolder="True"/> <me:OuterItem Name="Regular Item" IsFinished="True" Exists="True"/> <me:OuterItem Name="Yet to be created" IsFinished="False" Exists="False"/> <me:OuterItem Name="Just created" IsFinished="False" Exists="True"/> <me:OuterItem Name="In progress" IsFinished="False" Exists="True" Progress="0.7"/> </ListBox> where OuterItem is: public class OuterItem : IOuterItem { public Guid Id { get; set; } public string Name { get; set; } public bool IsFolder { get; set; } public bool IsFinished { get; set; } public bool Exists { get; set; } public double Progress { get; set; } /// Code below is of lesser importance, but anyway /// #region Visualization helper properties public bool ShowProgress { get { return !IsFinished && Exists; } } public string VisualName { get { return IsFolder ? "[ " + Name + " ]" : Name; } } #endregion public override string ToString() { if (IsFinished) return Name; if (!Exists) return " ??? " + Name; return Progress.ToString("0.000 ") + Name; } public static OuterItem Get(IOuterItem item) { return new OuterItem() { Id = item.Id, Name = item.Name, IsFolder = item.IsFolder, IsFinished = item.IsFinished, Exists = item.Exists, Progress = item.Progress }; } } ?onverters are: /// Are of lesser importance too (for understanding), but will be useful if you copy-paste to get it working public class BooleanToItalicsConverter : IValueConverter { public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { bool normal = (bool)value; return normal ? FontStyles.Normal : FontStyles.Italic; } public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { throw new NotImplementedException(); } } public class BooleanToVisibilityConverter : IValueConverter { public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { bool exists = (bool)value; return exists ? Visibility.Visible : Visibility.Collapsed; } public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { throw new NotImplementedException(); } } But most important, is that UserControl.Loaded() has: lbItems.Items.Clear(); lbItems.ItemsSource = fsItems; where fsItems is ObservableCollection<OuterItem>. The usability problem I describe takes place when I Clear() that collection (fsItems) and fill with new items.

  • c# - PubNub JSON serialization code works in example project but not in my project

    - by pilau
    I am making a Winamp plugin with the single function of sending the details of the song being played over HTTP to a webpage. It works like this: Winamp song event triggered - check for new song - publish to webpage using PubNub (C# API). So far I got to the stage where everything works exactly as it is supposed to, except for the PubNub code which doesn't serialize the object I'm passing for publishing into JSON. All I keep getting in the PubNub console is a mere {} - an empty JSON object. A little background on the project structure: I am using Sharpamp which is a custom library that enables making Winamp plugins with C#. I am also using the PubNub C# API. The gen_notifier_cs project is the C++ plugin wrapper created by Sharpamp. notifier_cs is where all my code resides. The two other projects are self explanatory I assume. I have referenced the PubNub API in notifier_cs, and also have referenced Sharpamp in both notifier_cs and PubNub API. So, the objects that need to get serialized are of a class Song as defined in Sharpamp: public class Song { public string Title { get; internal set; } public string Artist { get; internal set; } public string Album { get; internal set; } public string Year { get; internal set; } public bool HasMetadata { get; internal set; } public string Filename { get; internal set; } } So let's say if I have a song object with song data in it, I would go pubnub.publish("winamp_pipe", song); to publish it and PubNub will automatically serialize the data into JSON. But that's just not working in my solution. To test why it wasn't serializing, I copied that class to the example code file in the PubNub API. Visual Studio changed the class to this (notice the public Song() method): public class Song { public Song() { return; } public string Album { get; set; } public string Artist { get; set; } public string Filename { get; set; } public bool HasMetadata { get; set; } public string Title { get; set; } public string Year { get; set; } } On the same example file I initiated a default song object with some values: Song song = new Song(); song.Album = "albumname"; song.Artist = "artistname"; song.HasMetadata = true; song.Title = "songtitle"; song.Year = "2012"; And published it: pubnub.publish("winamp_pipe", song); and it worked! I got the JSON object in the PubNub channel! {"Album":"albumname","Artist":"artistname","Filename":null,"HasMetadata":true,"Title":"songtitle","Year":"2012"} So, I tried replacing the "new" Song class with the original one defined in Sharpamp. I tried adding another class definition in the notifier_cs project but that clashes with the one in Sharpamp which I have to rely on. I have been trying so many things as far as I could come up with. Needless to say none prevailed. Still, all I get is an empty JSON object. I have been pulling out my hair for the last day. I know this post is super long but I appreciate your input nonetheless. Thanks in advance.

  • integrating tinymce with asp .net MVC 4.0

    - by user1865670
    using ASP .NET MVC 4.0 , VS2012. In one of my page, I tried to integrate a WYSIWYG editor "TinyMCE". To integrate, I followed the following URL : .tugberkugurlu.com My view page is like : @model AboutModels @using FileUploadDemo.Models <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script> <script src="Scripts/tinymce/jquery.tinymce.js" type="text/javascript"></script> @{ ViewBag.Title = "About"; } @using (Html.BeginForm()) { @Html.ValidationSummary(true) <fieldset> <legend>About</legend> <div class="editor-label"> @Html.LabelFor(model => model.Title) </div> <div class="editor-field"> @Html.EditorFor(model => model.Title) @Html.ValidationMessageFor(model => model.Title) </div> <div class="editor-label"> @Html.LabelFor(model => model.PostedOn) </div> <div class="editor-field"> @Html.EditorFor(model => model.PostedOn) @Html.ValidationMessageFor(model => model.PostedOn) </div> <div class="editor-label"> @Html.LabelFor(model => model.Tags) </div> <div class="editor-field"> @Html.EditorFor(model => model.Tags) @Html.ValidationMessageFor(model => model.Tags) </div> <div class="editor-label"> @Html.LabelFor(model => model.Content) </div> <div class="editor-field"> @Html.EditorFor(model => model.Content) @Html.ValidationMessageFor(model => model.Content) </div> <p> <input type="submit" value="Create" /> </p> <p> Posted Content : @ViewBag.HtmlContent </p> </fieldset> } Here my Model is like : public class AboutModels { public string Title { get; set; } public DateTime PostedOn { get; set; } public string Tags { get; set; } [UIHint("tinymce_jquery_full"), AllowHtml] public string Content { get; set; } } My about page loads with all features. "@html.EditorFor(model=>model.content)" also loads fine. but no "WYSIWYG" pane(i donno what it is called, the pane is used to edit my text written in the textarea(HTml.editorFor())) is loaded. In the runtime, Exception is thrown in jquery.tinymce.js file. Error Message : `Unhandled exception at line 86, column 11 in http://localhost:1706/Home/About 0x800a01b6 - Microsoft JScript runtime error: Object doesn't support this property or method` And give me two options, Continue or Break . If i continue, the page loads with features as i mentioned earlier. If i Break, then it stays in the jquery.tinymce.js file with a yellow text-background. I have no experience with Javascript/jquery. And new in ASP .NET MVC 4.0, actually this is my first try of web application in .net. I updated jquery from nuGet. What could be the possible ways to solve it?

  • WPF Navigation Page Breadcrumb

    - by Ryan
    I found code to use a breadcrumb instead of the navigation buttons for my pages. This code works perfect with setting a page as the startup. My problem is that I need to have a window with a frame control as the startup and this is causing the breadcrumb to not show at all. I seem to be missing something with my styling. The types used to be NavigationWindow but I changed them to Frame to try and get a working solution. <Style TargetType="Frame" x:Key="{x:Type Frame}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="Frame"> <Grid Background="Transparent"> <Grid.RowDefinitions> <RowDefinition Height="50"/> <RowDefinition Height="50"/> <RowDefinition Height="*"/> </Grid.RowDefinitions> <ItemsControl ItemsSource="{Binding RelativeSource={RelativeSource AncestorType={x:Type Frame}}, Path=BackStack}"> <!--Force the ItemsContol to use a wrap panel as Items host--> <ItemsControl.ItemsPanel> <ItemsPanelTemplate> <local:InverseWrapPanel KeyboardNavigation.TabNavigation="Cycle" KeyboardNavigation.DirectionalNavigation="Cycle"/> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> <ItemsControl.ItemTemplate> <DataTemplate> <Button Command="NavigationCommands.NavigateJournal" CommandParameter="{Binding RelativeSource={RelativeSource Self}}" Content="{Binding Name}"> <Button.Template> <ControlTemplate TargetType="Button"> <WrapPanel> <TextBlock Name="text1" FontWeight="Bold" Text="{TemplateBinding Content}"/> <TextBlock Name="text2" FontWeight="Bold" Text=">>" Margin="2,0,0,0"/> </WrapPanel> <ControlTemplate.Triggers> <Trigger Property="IsMouseOver" Value="True"> <Setter TargetName="text1" Property="Foreground" Value="Blue"/> <Setter TargetName="text2" Property="Foreground" Value="Blue"/> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> </Button.Template> </Button> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> <AdornerDecorator Grid.Row="2"> <ContentPresenter Name="PART_NavWinCP" ClipToBounds="true"/> </AdornerDecorator> </Grid> </ControlTemplate> </Setter.Value> </Setter> </Style>

  • Simple animation using C#/Windows Forms

    - by clintp
    I need to knock out a quick animation in C#/Windows Forms for a Halloween display. Just some 2D shapes moving about on a solid background. Since this is just a quick one-off project I really don't want to install and learn an entire new set of tools for this. (DirectX dev kits, Silverlight, Flash, etc..) I also have to install this on multiple computers so anything beyond the basic .Net framework (2.0) would be a pain in the arse. For tools I've got VS2k8, 25 years of development experience, a wheelbarrow, holocaust cloak, and about 2 days to knock this out. I haven't done animation since using assembler on my Atari 130XE (hooray for page flipping and player/missile graphics!) Advice? Here's some of the things I'd like to know: I can draw on any empty widget (like a panel) by fiddling with it's OnPaint handler, right? That's how I'd draw a custom widget. Is there a better technique than this? Is there a page-flipping technique for this kind of thing in Windows Forms? I'm not looking for a high frame rate, just as little flicker/drawing as necessary. Thanks. Post Mortem Edit ... "a couple of coding days later" Well, the project is done. The links below came in handy although a couple of them were 404. (I wish SO would allow more than one reply to be marked "correct"). The biggest problem I had to overcome was flickering, and a persistent bug when I tried to draw on the form directly. Using the OnPaint event for the Form: bad idea. I never got that to work; lots of mysterious errors (stack overflows, or ArgumentNullExceptions). I wound up using a panel sized to fill the form and that worked fine. Using the OnPaint method is slow anyway. Somewhere online I read that building the PaintEventArgs was slow, and they weren't kidding. Lots of flickering went away when I abandoned this. Skip the OnPaint/Invalidate() and just paint it yourself. Setting all of the "double buffering" options on the form still left some flicker that had to be fixed. (And I found conflicting docs that said "set them on the control" and "set them on the form". Well controls don't have a .SetStyle() method.) I haven't tested without them, so they might be doing something (this is the form): this.SetStyle(ControlStyles.UserPaint, true); this.SetStyle(ControlStyles.OptimizedDoubleBuffer, true); this.SetStyle(ControlStyles.AllPaintingInWmPaint, true); So the workhorse of the code wound up looking like (pf is the panel control): void PaintPlayField() { Bitmap bufl = new Bitmap(pf.Width, pf.Height); using (Graphics g = Graphics.FromImage(bufl)) { g.FillRectangle(Brushes.Black, new Rectangle(0, 0, pf.Width, pf.Height)); DrawItems(g); DrawMoreItems(g); pf.CreateGraphics().DrawImageUnscaled(bufl, 0, 0); } } And I just called PaintPlayField from the inside of my Timer loop. No flicker at all.

  • ModalPopupExtender z-index value decreases after every show

    - by ryanulit
    This is a new one I have never seen before. I have a gridview containing a bunch of categories that can be edited by clicking on the respective "Edit" link within the gridview. The modalpopupextender is then shown programmatically (.show() method) and the user is allowed to edit the category. Then the modal popup is programmtically hidden (.hide() method) when the user presses "Update" or "Cancel". For some reason after every new show of the modal popup, the z-index is decreasing by 1000 until it is hidden behind everything on my page. It starts at 7000 for the very first show. Therefore the user would not be able to edit an infinite number of categories if they wanted to. Any ideas why this is happening? Css class used on modalpopupextender: DIV.box-pop { border: #95aab9 1px solid; background-color: #ECF1F5; display: block; position: relative; margin: -6px 6px 6px -6px; padding: 4px; z-index: 10000; } Panel used for popup: <asp:Panel ID="PanelModify" runat="server" Width="250px" CssClass="box-pop"> <asp:UpdatePanel ID="UpdatePanelModify" runat="server" UpdateMode="Conditional"> <ContentTemplate> <table width="100%" cellpadding="3" cellspacing="3"> <tr> <td> <div class="box"> <h1> <span><strong> <asp:Literal ID="LiteralModalTitle" runat="server" /></strong></span> </h1> <table border="0" width="100%"> <tr> <td> <asp:TextBox ID="TextBoxModifiedText" runat="server" Width="173px" ValidationGroup="Modify"></asp:TextBox> <asp:RequiredFieldValidator ID="RequiredFieldValidatorModifiedText" runat="server" ValidationGroup="Modify" ErrorMessage="*" ControlToValidate="TextBoxModifiedText" Display="Dynamic"> </asp:RequiredFieldValidator> </td> </tr> <tr> <td> <asp:Button ID="ButtonUpdate" runat="server" Text="Update" ValidationGroup="Modify" /><asp:Button ID="ButtonInsert" runat="server" Text="Insert" ValidationGroup="Modify" /> &nbsp; <asp:Button ID="ButtonCancel" runat="server" Text="Cancel" CausesValidation="false" /> </td> </tr> </table> </div> </td> </tr> </table> </ContentTemplate> </asp:UpdatePanel> </asp:Panel> <ajaxToolkit:ModalPopupExtender ID="ModalPopupExtenderModify" runat="server" PopupControlID="PanelModify" TargetControlID="ButtonHideModify" BackgroundCssClass="modalBackground"> </ajaxToolkit:ModalPopupExtender> <asp:Button ID="ButtonHideModify" runat="server" Style="display: none;" />

    - by user329540
    I have a MVC4 asp.net application, I have two layouts a main layout for the main page and a second layout for the nested pages. The problem I have is with the second layout, on this layout I call a partial view which has my navigation links. In IE the navigation menu displays fine and when each item is clicked it navigates as expected. However in FF when the page renders the navigation bar is displayed but it has no 'click functionality' if you will its as if its simply text. My layout of nested page: <header> <img src="../../Images/fronttop.png" id="nestedPageheader" alt="Background Img"/> <div class="content-wrapper"> <section > <nav> <div id="navcontainer"> </div> </nav> </section> <div> </header> The script to retreive partial view and information for dynamic links on layout page. <script type="text/javascript"> var menuLoaded = false; $(document).ready(function () { if($('#navcontainer')[0].innerHTML.trim() == "") { $.ajax({ url: "@Url.Content("~/Home/MenuLayout")", type: "GET", success: function (response, status, xhr) { var nvContainer = $('#navcontainer'); nvContainer.html(response); menuLoaded = true; }, error: function (XMLHttpRequest, textStatus, errorThrown) { var nvContainer = $('#navcontainer'); nvContainer.html(errorThrown); } }); } }); </script> May partial view: @model Mscl.OpCost.Web.Models.stuffmodel <div class="menu"> <ul> <li><a>@Html.ActionLink("Home", "Index", "Home")</a></li> <li><a>@Html.ActionLink("some stuff", "stuffs", "stuff")</a></li> <li> <h5><a><span>somestuff</span></a></h5> <ul> <li><a>stuffs1s</a> <ul> @foreach (var image in Model.stuffs.Where(g => g.Grouping == 1)) { <li> <a>@Html.ActionLink(image.Title, "stuffs", "stuff", new { Id = image.CategoryId }, null)</a> </li> } </ul> </li> </ul> </il> </ul> </div> I need to know why this works fine in IE but why its not working in FF(all versions). Any assistance would be appreciated.

  • Is this question too hard for a seasoned C++ architect?

    - by Monomer
    Background Information We're looking to hire a seasoned C++ architect (10+years dev, of which at least 6years must be C++ ) for a high frequency trading platform. Job advert says STL, Boost proficiency is a must with preferences to modern uses of C++. The company I work for is a Fortune 500 IB (aka finance industry), it requires passes in all the standard SHL tests (numeric, vocab, spatial etc) before interviews can commence. Everyone on the team was given the task of coming up with one question to ask the candidates during a written/typed test, please note this is the second test provided to the candidates, the first being Advanced IKM C++ test, done in the offices supervised and without internet access. People passing that do the second test. After roughly 70 candidates, my question has been determined to be statistically the worst performing - aka least number of people attempted it, furthermore even less people were able to give meaningful answers. Please note, the second test is not timed, the candidate can literally take as long as they like (we've had one person take roughly 10.5hrs) My question to SO is this, after SHL and IKM adv c++ tests, backed up with at least 6+ years C++ development experience, is it still ok not to be able to even comment about let alone come up with some loose strategy for solving the following question. The Question There is a class C with methods foo, boo, boo_and_foo and foo_and_boo. Each method takes i,j,k and l clock cycles respectively, where i < j, k < i+j and l < i+j. class C { public: int foo() {...} int boo() {...} int boo_and_foo() {...} int foo_and_boo() {...} }; In code one might write: C c; . . int i = c.foo() + c.boo(); But it would be better to have: int i = c.foo_and_boo(); What changes or techniques could one make to the definition of C, that would allow similar syntax of the original usage, but instead have the compiler generate the latter. Note that foo and boo are not commutative. Possible Solution We were basically looking for an expression templates based approach, and were willing to give marks to anyone who had even hinted or used the phrase or related terminology. We got only two people that used the wording, but weren't able to properly describe how they accomplish the task in detail. We use such techniques all over the place, due to the use of various mathematical operators for matrix and vector based calculations, for example to decide when to use IPP or hand woven implementations at compile time for a particular architecture and many other things. The particular area of software development requires microsecond response times. I believe could/should be able to teach a junior such techniques, but given the assumed caliber of candidates I expected a little more. Is this really a difficult question? Should it be removed? Or are we just not seeing the right candidates?

  • Taking screenshots in Windows Vista, Windows 7, with transparent areas outside the app region

    - by Steve Sheldon
    Hey Folks, I am trying to take a screenshot of an application and I would like to make the parts of the rectangle that are not part of the applications region be transparent. So for instance on a standard windows application I would like to make the rounded corners transparent. I wrote a quick test application which works on on XP (or vista/windows 7 with aero turned off): protected override void OnPaint(PaintEventArgs e) { base.OnPaint(e); Graphics g = e.Graphics; // Just find a window to test with IntPtr hwnd = FindWindowByCaption(IntPtr.Zero, "Calculator"); WINDOWINFO info = new WINDOWINFO(); info.cbSize = (uint)Marshal.SizeOf(info); GetWindowInfo(hwnd, ref info); Rectangle r = Rectangle.FromLTRB(info.rcWindow.Left, info.rcWindow.Top, info.rcWindow.Right, info.rcWindow.Bottom); IntPtr hrgn = CreateRectRgn(info.rcWindow.Left, info.rcWindow.Top, info.rcWindow.Right, info.rcWindow.Bottom); GetWindowRgn(hwnd, hrgn); // fill a rectangle which would be where I would probably // write some mask color g.FillRectangle(Brushes.Red, r); // fill the region over the top, all I am trying to do here // is show the contrast between the applications region and // the rectangle that the region would be placed in Region region = Region.FromHrgn(hrgn); region.Translate(info.rcWindow.Left, info.rcWindow.Top); g.FillRegion(Brushes.Blue, region); } Quick side note: before commenting that this code is doing stuff it shouldn't (or should do, like dispose) in a paint function, I know, it's not going anywhere but this post and is designed purely as a way to quickly show the problem, and that it does... OK, back to the problem ;) When I run this test app on XP (or Vista/Windows 7 with Aero off), I get something like this, which is great because I can eek an xor mask out of this that can be used later with BitBlt. Here is the problem, on Vista or Windows 7 with Aero enabled, there isn't necessarily a region on the window, in fact in most cases there isn't. Can anybody help me figure out how to get the region of the application like this on these platforms. Here are some of the approaches I have already tried... 1. Using the PrintWindow function: This doesn't work because it gives back a screenshot taken of the window with Aero off and this window is a different shape from the window returned with Aero on 2 Using the Desktop Window Manager API to get a full size thumbnail: This didn't work because it draws directly to the screen and from what I can tell you can't get a screenshot directly out of this api. Yeah, I could open a window with a pink background, show the thumbnail, take a screenshot then hide this temporary window but thats a horrible user experience and a complete hack I would rather not have my name on. 3. Using Graphics.CopyFromScreen or some other pinvoke variant of this: This doesn't work because I can't assume that the window I need information from is at the top of the z-order on the screen. Right now, the best solution I can think of is to special case Aero on Windows 7 and Vista to manually rub out the corners by hard coding some graphics paths I paint out but this solution would suck since any application that performs custom skinning will break this. Can you think of another or better solution? If you are here, thanks for taking time to read this post, I appreciate any help or direction that you can offer!

  • rendering a grid from a table: "this.mainBody is undefined"

    - by farhad
    Hello! I have a static html table on a page and i would like to transform it to a grid; so i applied this function after loading the table: function createTable() { // create the grid var grid = new Ext.ux.grid.TableGrid("tabella-colocazioni", { stripeRows: true // stripe alternate rows }); grid.render(); } I got this piece of code from here: http://www.java2s.com/Code/JavaScript/Ext-JS/CreateagridwithfromanexistingunformattedHTMLtable.htm . The result is the error "this.mainBody is undefined on ext-all-debug.js" on FireBug and the grid is empty. The html code of the table is this: <table cellspacing="0" id="tabella-colocazioni"> <thead> <tr style="background:#eeeeee;"> <th>Colocazione</th> <th>Frequenza</th> </tr> </thead> <tbody> <tr> <td>plusquam patria</td> <td>1</td> </tr> <tr> <td>patria pietate</td> <td>1</td> </tr> <tr> <td>Et patria</td> <td>1</td> </tr> <tr> <td>patria prohibet</td> <td>1</td> </tr> <tr> <td>Multos patria</td> <td>1</td> </tr> <tr> <td>patria reddidit</td> <td>1</td> </tr> <tr> <td>patronum patria</td> <td>1</td> </tr> <tr> <td>patria moesta</td> <td>1</td> </tr> </tbody> </table> What is the problem?

  • Jquery fadeOut looking different in FF than in Chrome/Safari

    - by StealthRT
    Hey all, i have a page that when a user desides to delete a company, it fades out using the jquery fadeOut() command. This works great and does as it should in FireFox but for some reason it doesn't do the same in Chrome/Safari browsers. The problem is that i have a png image overlay on top of the company logo image that also fades out with the company logo. But if there are more than one company logo on the page, it moves the others in the place where the one got deleted. Like i said, it works fine (and as it should) in Firefox and even IE (SHOCK!) but not in Chrome or Safari. This is the code i use to delete (fade out) the section: $('#moreInfoM' + theNum).fadeOut("slow"); $('#moreInfo' + theNum).fadeOut("slow"); $('#liNum' + theNum).fadeOut("slow"); Where moreInfoM, moreInfo & liNum are all within the code for each logo image. TheNum is just a unique number for each logo just for reference. And the ASP code: For iLoop = LBound(compNames) to UBound(compNames) theWidth = (iwidth / 2) ImgDimension(Server.MapPath("img/company/" & compNames(iLoop) & ".jpg")) theWidth = (iwidth / 2) response.write "<li onClick=""$('#moreInfo" & y & "').slideToggle('slow');"" id=""liNum" & y & """>" & vbcr if theBrowser = "chrome" or theBrowser = "safari" then response.write "<img src=""img/clickMI.png"" width=""97"" height=""33"" style=""position:absolute;width:97px;height:33px;z-index:12;padding-top: 54px; padding-left:" & theWidth & "px;"">" & vbcr else response.write "<img src=""img/clickMI.png"" width=""97"" height=""33"" style=""position:absolute;width:97px;height:33px;z-index:12;padding-top: 50px; padding-left:" & theWidth & "px;"">" & vbcr end if response.write "<img src=""img/company/" & compNames(iLoop) & ".jpg"" height=""60"" style=""border: 1px solid #4C3C1B;padding: 2px;background-color: #CCC; margin-left: 10px; margin-right: 10px; margin-bottom: 5px; margin-top: 5px;"" id=""moreInfoM" & y & """ />" & vbcr response.write "</li>" & vbcr y = y + 1 Next I have made a video of FF and Chrome to give you a better understanding. http://www.youtube.com/watch?v=ZQaRvosvRKE Thanks!

  • ASP.net roles and Projects

    - by Zyphrax
    EDIT - Rewrote my original question to give a bit more information Background info At my work I'm working on a ASP.Net web application for our customers. In our implementation we use technologies like Forms authentication with MembershipProviders and RoleProviders. All went well until I ran into some difficulties with configuring the roles, because the roles aren't system-wide, but related to the customer accounts and projects. I can't name our exact setup/formula, because I think our company wouldn't approve that... What's a customer / project? Our company provides management information for our customers on a yearly (or other interval) basis. In our systems a customer/contract consists of: one Account: information about the Company per Account, one or more Products: the bundle of management information we'll provide per Product, one or more Measurements: a period of time, in which we gather and report the data Extranet site setup Eventually we want all customers to be able to access their management information with our online system. The extranet consists of two sites: Company site: provides an overview of Account information and the Products Measurement site: after selecting a Measurement, detailed information on that period of time The measurement site is the most interesting part of the extranet. We will create submodules for new overviews, reports, managing and maintaining resources that are important for the research. Our Visual Studio solution consists of a number of projects. One web application named Portal for the basis. The sites and modules are virtual directories within that application (makes it easier to share MasterPages among things). What kind of roles? The following users (read: roles) will be using the system: Admins: development users :) (not customer related, full access) Employees: employees of our company (not customer related, full access) Customer SuperUser: top level managers (full access to their account/measurement) Customer ContactPerson: primary contact (full access to their measurement(s)) Customer Manager: a department manager (limited access, specific data of a measurement) What about ASP.Net users? The system will have many ASP.Net users, let's focus on the customer users: Users are not shared between Accounts SuperUser X automatically has access to all (and new) measurements User Y could be Primary contact for Measurement 1, but have no role for Measurement 2 User Y could be Primary contact for Measurement 1, but have a Manager role for Measurement 2 The department managers are many individual users (per Measurement), if Manager Z had a login for Measurement 1, we would like to use that login again if he participates in Measurement 2. URL structure These are typical urls in our application: http://host/login - the login screen http://host/project - the account/product overview screen (measurement selection) http://host/project/1000 - measurement (id:1000) details http://host/project/1000/planning - planning overview (for primary contact/superuser) http://host/project/1000/reports - report downloads (manager department X can only access report X) We will also create a document url, where you can request a specific document by it's GUID. The system will have to check if the user has rights to the document. The document is related to a Measurement, the User or specific roles have specific rights to the document. What's the problem? (finally ;)) Roles aren't enough to determine what a user is allowed to see/access/download a specific item. It's not enough to say that a certain navigation item is accessible to Managers. When the user requests Measurement 1000, we have to check that the user not only has a Manager role, but a Manager role for Measurement 1000. Summarized: How can we limit users to their accounts/measurements? (remember superusers see all measurements, some managers only specific measurements) How can we apply roles at a product/measurement level? (user X could be primarycontact for measurement 1, but just a manager for measurement 2) How can we limit manager access to the reports screen and only to their department's reports? All with the magic of asp.net classes, perhaps with a custom roleprovider implementation.

  • jQuery Map Highlight - works fine at DOM ready but failed when loaded by AJAX

    - by Michael Mao
    Hi all: This is uni assignment and I have already done some stuff. Please go to the password protected directory on : my server Enter username "uts" and password "10479475", both without quotes, into the prompt and you shall be able to see the webpage. Basically, if you hover your mouse on top of the contents in worldmap to the upperleft corner, you can see the underneath area is "highlighted" by a gray region and a red border. This is done using one jQuery plugin : at here This part works fine, however, after I use jQuery to load the specific continent map asynchronously, the newly loaded image cannot work correctly. Tested under Firebug, I can see the plugin doesn't "like" the new image cause I cannot find the canvas or other auto-generated stuff which can be founded around the worldmap. All the functionality is done in master.js, I believe you can just download a copy and check the code there. I do hope that I have followed the tutorials on the plugin's doc page, but I just cannot get through the final stage. Code used for worldmap in html: <img id="worldmap" src="./img/world.gif" alt="world.gif" width="398" height="200" class="map" usemap="#worldmap"/> <map name="worldmap"> <area class='continent' href="#" shape="poly" title="North_America" coords="1,39, 40,23, 123,13, 164,17, 159,40, 84,98, 64,111, 29,89" /> </map> Code used for worldmap in master.js //when DOM is ready, do something $(document).ready(function() { $('.map').maphilight(); //call the map highlight main function } On contrast, code used for specific continent map: //helper function to load specific continent map using AJAX function loadContinentMap(continent) { $('#continent-map-wrapper').children().remove(); //remove all children nodes first //inspiration taken from online : http://jqueryfordesigners.com/image-loading/ $('#continent-map-wrapper').append("<div id='loader' class='loading'><div>"); var img = new Image(); // wrap our new image in jQuery, then: // once the image has loaded, execute this code $(img).load(function () { $(this).hide(); // set the image hidden by default // with the holding div #loader, apply: // remove the loading class (so no background spinner), // then insert our image $('#loader').removeClass('loading').append(this); // fade our image in to create a nice effect $(this).fadeIn(); }).error(function () { // if there was an error loading the image, react accordingly // notify the user that the image could not be loaded $('#loader').removeClass('loading').append("<h1><div class='errormsg'>Loading image failed, please try again! If same error persists, please contact webmaster.</div></h1>"); }) //set a series of attributes to the img tag, these are for the map high lighting plugin. .attr('id', continent).attr('alt', '' + continent).attr('width', '576').attr('height', '300') .attr('usemap', '#city_' + continent).attr('class', 'citymap').attr('src', './img/' + continent + '.gif'); // *finally*, set the src attribute of the new image to our image //After image is loaded, apply the map highlighting plugin function again. $('.citymap').maphilight(); $('area.citymap').click(function() { alert($(this).attr('title') + ' is clicked!'); }); } Sorry about the messy code, havn't refactored it yet. I am wondering why the canvas disappers for the continent map. Did I do anything wrong. Any hint is much appreciated and thanks for any suggestion in advance!

  • Dynamic Scoped Resources in WPF/XAML?

    - by firoso
    I have 2 Xaml files, one containing a DataTemplate which has a resource definition for an Image brush, and the other containing a content control which presents this DataTemplate. The data template is bound to a view model class. Everything seems to work EXCEPT the ImageBrush resource, which just shows up white... Any ideas?

  • Any tool to make git build every commit to a branch in a seperate repository?

    - by Wayne
    A git tool that meets the specs below is needed. Does one already exists? If not, I will create a script and make it available on GitHub for others to use or contribute. Is there a completely different and better way to solve the need to build/test every commit to a branch in a git repository? Not just to the latest but each one back to a certain staring point. Background: Our development environment uses a separate continuous integration server which is wonderful. However, it is still necessary to do full builds locally on each developer's PC to make sure the commit won't "break the build" when pushed to the CI server. Unfortunately, with auto unit tests, those build force the developer to wait 10 or 15 minutes for a build every time. To solve this we have setup a "mirror" git repository on each developer PC. So we develop in the main repository but anytime a local full build is needed. We run a couple commands in a in the mirror repository to fetch, checkout the commit we want to build, and build. It's works extremely lovely so we can continue working in the main one with the build going in parallel. There's only one main concern now. We want to make sure every single commit builds and tests fine. But we often get busy and neglect to build several fresh commits. Then if it the build fails you have to do a bisect or manually figure build each interim commit to figure out which one broke. Requirements for this tool. The tool will look at another repo, origin by default, fetch and compare all commits that are in branches to 2 lists of commits. One list must hold successfully built commits and the other lists commits that failed. It identifies any commit or commits not yet in either list and begins to build them in a loop in the order that they were committed. It stops on the first one that fails. The tool appropriately adds each commit to either the successful or failed list after it as attempted to build each one. The tool will ignore any "legacy" commits which are prior to the oldest commit in the success list. This logic makes the starting point possible in the next point. Starting Point. The tool building a specific commit so that, if successful it gets added to the success list. If it is the earliest commit in the success list, it becomes the "starting point" so that none of the commits prior to that are examined for builds. Only linear tree support? Much like bisect, this tool works best on a commit tree which is, at least from it's starting point, linear without any merges. That is, it should be a tree which was built and updated entirely via rebase and fast forward commits. If it fails on one commit in a branch it will stop without building the rest that followed after that one. Instead if will just move on to another branch, if any. The tool must do these steps once by default but allow a parameter to loop with an option to set how many seconds between loops. Other tools like Hudson or CruiseControl could do more fancy scheduling options. The tool must have good defaults but allow optional control. Which repo? origin by default. Which branches? all of them by default. What tool? by default an executable file to be provided by the user named "buildtest", "buildtest.sh" "buildtest.cmd", or buildtest.exe" in the root folder of the repository. Loop delay? run once by default with option to loop after a number of seconds between iterations.

  • Xcode/iPhone Development 6 months in - Annoyances

    - by clearbrian
    Hi I've been iPhone programming for 6 months and come from a PC/Java/Eclipse background and still have a few annoyances with Xcode/iPhone programming I wonder are there any shortcuts to. Is there any way to prevent multiple windows opening all the time in XCode? a) When you click on the Errors/Warnings in the bottom right of the status bar build errors are shown in separate window. Any way to get these to show in the main editor? b) Anyway to get debugger to appear in main editor. I have a big screen iMac and it's still window hell on Macs. When you come from Alt-Tab the Mac is a nightmare. 2) Anyway to get a toolbar item on the main editor to: a) Open Console (I know CMD-thingy-R) b) Open Break points (you have to open Debugger first then breakpoints) I know there's keyboard shortcuts but I have only left hand free others on the trackball so any keys on right hand side of keyboard are too far. I know you can add Finder toolbar scripts (just wondering if anyway to extend Xcode). Are there utilities to extend Xcode? Scripts/Automator/Any Services I can setup to help. Can you automate Xcode like you can with Windows/ActiveX/VBA 3) Limit lookups using CMD + double click. If I double click on a variable to find its definition using CMD + double click it shows every occurrence of all variables with that name. (annoying it you name all you maps mapView) Anyway to get it to limit to the current class or at least order so current class is first. 4) Find doesn't seem to loop backwards if result all above cursor position I'm in a class and I hit CMD + F for find. Find box appears. I enter some text hit return. It says I have x matches but only back arrow is highlight in Find But when I hit < it does nothing. I need to scroll to the top and redo the search. If the text is both forwards and backwards then both < are highlighted and it works. is this a bug or a 'feature' Missing Eclipse features I have been looking at the User Script menu but was wondering how powerful they are? 5) any scripts around to generate source from members such as description: @property @synthesize if I add a new member, run a script will generate @property/@syntesize and release in dealloc 7) any good sites for scripts? SCM Im having problems with SCM and Folders on HD under project Classes directory. You get a library e.g. JSON. It usually comes as a folder. You copy it to the /Classes for your project. /Classes/JSON I create a Group for the Library in Xcode under Classes group. Classes JSON I drag the files from the folder into xcode into the JSON Group. I add them to the SCM and icon changes from ? to A but if I try and commit them it say folder /JSON is not under SCM. Can you drag a folder into Xcode so that it AND its files get included in SCM? Anyway to stop Xcode Help from being on top all the time. I keep feeling like punching it and telling it to get out of the way! :) I dont mind it open just not in the way once I've finished. Yes I know I can Ctrl-W Sites: the main site I use to learn Obj-C are : stackoverflow.com Google code Search - tonnes of full apps on here http://www.iphonedevsdk.com/forum/iphone-sdk-development/ Apple Developers Forums (anyway to get RSS feed to these or is that blasphemy :) ) Safari - 100s of IT book though prob too many to keep up :) any others? Any site that gives simple examples for Obj-C/ UIKit The docs just show the methods but actual examples (Google code search has helped a lot here)

  • ScrollView in android

    - by rantravee
    hi, I' have a view that contains several textViews an ImageView and a Button . Because on small screen devices (or in landscape mode on big ones ) not all are visible I use a Scroll as the parent of the whole hierarchy to allow the user to view all the information. The things are suck that the button must be at the buttom of the view . However on big screen device , where it remains enough space at the buttom , the button is put immediatelly below the last textview,and seems to occupy all the remaining space (resulting in an unnactractive view) . Trying to use android:allignParentButtom ="true" not only that it has no effect but it puts the button at top of the screen . Has anyone any ideea how could I accomplish what I described ? here's the xml <?xml version="1.0" encoding="utf-8"?> <ScrollView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/scroll_view" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerHorizontal="true"> <RelativeLayout android:id="@+id/gps_info_page1" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_centerHorizontal="true"> <TextView android:id="@+id/itsDateTimeValue" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:layout_centerHorizontal="true" android:text="@string/eStrUnknown"> </TextView> <RelativeLayout android:id="@+id/directions" android:layout_centerHorizontal="true" android:layout_below="@+id/itsDateTimeValue" android:layout_width="wrap_content" android:layout_height="wrap_content"> <TextView android:id="@+id/itsDirectionValue" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="0" android:layout_marginRight="2dip" android:textSize="20sp"> </TextView> <TextView android:id="@+id/itsOrientation" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textSize="20sp" android:layout_marginLeft="2dip" android:text="@string/eStrUnknown" android:layout_toRightOf="@+id/itsDirectionValue"> </TextView> </RelativeLayout> <ImageView android:id="@+id/itsImage" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/compass" android:layout_below="@+id/directions" android:layout_centerHorizontal="true"> </ImageView> <RelativeLayout> ..."TextViews below the above image" </RelativeLayout> <RelativeLayout> ..."TextViews below the above" </RelativeLayout> <RelativeLayout> ..."TextViews below the above" </RelativeLayout> <RelativeLayout> ..."TextViews below the above" </RelativeLayout> <RelativeLayout ..."TextViews below the above" </RelativeLayout> <LinearLayout android:id="@+id/div" android:layout_width="fill_parent" android:layout_height="1dip" android:layout_below="@+id/sunset_layout" android:background="#F333"> </LinearLayout> <Button //adding here android:alignParentBottom="true" has described above behavior android:layout_marginBottom="3dip" android:layout_marginTop="20dip" android:id="@+id/done_button" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/eStrDone" android:textSize="18sp" android:layout_below="@+id/div" android:layout_centerHorizontal="true"> </Button> </RelativeLayout> </ScrollView>
