  • css coding on Myspace - Problem

    - by Frederik Wessberg
    Hey Folks. I've read what I could, and I'm certainly no master, but I'm fixing up a colleagues profile on myspace.com, and im working with 2 divs in each side of the screen, and I want them to align so that they are next to each other. I've tried float: left; and float: right;, and I've tried margin: right; on div 1 and such. Could you help?

  • Accessing contents of NativeWindow in a HTML AIR application?

    - by Dan Scotton
    I'm currently building a HTML/JS AIR application. The application needs to display to the user a different 'window' - dependant on whether this is the first time they've launched the application or not. This part is actually fine and I have the code below to do that: if(!startUp()) { // this simply returns a boolean from a local preferences database that gets shipped with the .air // do first time stuff var windowOptions = new air.NativeWindowInitOptions(); windowOptions.systemChrome = 'none'; windowOptions.type = 'lightweight'; windowOptions.transparent = 'true'; windowOptions.resizable = 'false'; var windowBounds = new air.Rectangle(300, 300, 596, 490); var newHtmlLoader = air.HTMLLoader.createRootWindow(true, windowOptions, true, windowBounds); newHtmlLoader.load(new air.URLRequest('cover.html')); } else { // display default window // just set nativeWindow.visible = true (loaded from application.xml) } However, what I want to be able to do is manipulate the html content from within cover.html after it has loaded up. There seems to be plenty of tutorials online of how to move, resize, etc. the NativeWindow, but I simply want access to the NativeWindow's HTML content. For example, how would I add a new paragraph to that page? I've tried the following: newHtmlLoader.window.opener = window; var doc = newHtmlLoader.window.opener.document.documentElement; Using AIR's Introspector console, ....log(doc) returns [object HTMLHtmlElement]. Hmm, seems promising right? I then go on to try: var p = document.createElement('p'); var t = document.createTextNode('Insert Me'); p.appendChild(t); doc.appendChild(p); ...but nothing gets inserted. I've also tried the following replacements for doc: var doc = newHtmlLoader.window.opener.document.body; // .log(doc) -> [object HTMLBodyElement] var doc = newHtmlLoader.window.opener.document; // .log(doc) -> Error: HIERARCHY_REQUEST_ERR: DOM Exception 3 ...as well as the following with jQuery: $(doc).append('<p>Insert Me</p>'); // again, nothing So, anyone had any experience in accessing a NativeWindow's inner content programmatically? Any help will be greatly appreciated.

  • Windows splash screen using GDI+

    - by Luther
    The eventual aim of this is to have a splash screen in windows that uses transparency but that's not what I'm stuck on at the moment. In order to create a transparent window, I'm first trying to composite the splash screen and text on an off screen buffer using GDI+. At the moment I'm just trying to composite the buffer and display it in response to a 'WM_PAINT' message. This isn't working out at the moment; all I see is a black window. I imagine I've misunderstood something with regards to setting up render targets in GDI+ and then rendering them (I'm trying to render the screen using straight forward GDI blit) Anyway, here's the code so far: //my window initialisation code void MyWindow::create_hwnd(HINSTANCE instance, const SIZE &dim) { DWORD ex_style = WS_EX_LAYERED ; //eventually I'll be making use of this layerd flag m_hwnd = CreateWindowEx( ex_style, szFloatingWindowClass , L"", WS_POPUP , 0, 0, dim.cx, dim.cy, null, null, instance, null); SetWindowLongPtr(m_hwnd ,0, (__int3264)(LONG_PTR)this); m_display_dc = GetDC(NULL); //This was sanity check test code - just loading a standard HBITMAP and displaying it in WM_PAINT. It worked fine //HANDLE handle= LoadImage(NULL , L"c:\\test_image2.bmp", IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE); m_gdip_offscreen_bm = new Gdiplus::Bitmap(dim.cx, dim.cy); m_gdi_dc = Gdiplus::Graphics::FromImage(m_gdip_offscreen_bm);//new Gdiplus::Graphics(m_splash_dc );//window_dc ;m_splash_dc //this draws the conents of my splash screen - this works if I create a GDI+ context for the window, rather than for an offscreen bitmap. //For all I know, it might actually be working but when I try to display the contents on screen, it shows a black image draw_all(); //this is just to show that drawing something simple on the offscreen bit map seems to have no effect Gdiplus::Pen pen(Gdiplus::Color(255, 0, 0, 255)); m_gdi_dc->DrawLine(&pen, 0,0,100,100); DWORD last_error = GetLastError(); //returns '0' at this stage } And here's the snipit that handles the WM_PAINT message: ---8<----------------------- //Paint message snippit case WM_PAINT: { BITMAP bm; PAINTSTRUCT ps; HDC hdc = BeginPaint(vg->m_hwnd, &ps); //get the HWNDs DC HDC hdcMem = vg->m_gdi_dc->GetHDC(); //get the HDC from our offscreen GDI+ object unsigned int width = vg->m_gdip_offscreen_bm->GetWidth(); //width and height seem fine at this point unsigned int height = vg->m_gdip_offscreen_bm->GetHeight(); BitBlt(hdc, 0, 0, width, height, hdcMem, 0, 0, SRCCOPY); //this blits a black rectangle DWORD last_error = GetLastError(); //this was '0' vg->m_gdi_dc->ReleaseHDC(hdcMem); EndPaint(vg->m_hwnd, &ps); //end paint return 1; } ---8<----------------------- My apologies for the long post. Does anybody know what I'm not quite understanding regarding how you write to an offscreen buffer using GDI+ (or GDI for that matter)and then display this on screen? Thank you for reading.

  • WPF: How to properly override the methods when creating custom control

    - by EV
    Hi, I am creating a custom control Toolbox that is derived from ItemsControl. This toolbox is supposed to be filled with icons coming from the database. The definition looks like this: public class Toolbox : ItemsControl { protected override DependencyObject GetContainerForItemOverride() { return new ToolboxItem(); } protected override bool IsItemItsOwnContainerOverride(object item) { return (item is ToolboxItem); } } Toolboxitem is derived from ContentControl. public class ToolboxItem : ContentControl { static ToolboxItem() { FrameworkElement.DefaultStyleKeyProperty.OverrideMetadata(typeof(ToolboxItem), new FrameworkPropertyMetadata(typeof(ToolboxItem))); } } Since the number of icons stored in a database is not known I want to use the data template: <DataTemplate x:Key="ToolBoxTemplate"> <StackPanel> <Image Source="{Binding Path=url}" /> </StackPanel> </DataTemplate> Then I want the Toolbox to use the template. <Toolbox x:Name="NewLibrary" ItemsSource="{Binding}" ItemTemplate="ToolBoxtemplate"> </Toolbox> I'm using ADO.NET entity framework to connect to a database. The code behind: SystemicsAnalystDBEntities db = new SystemicsAnalystDBEntities(); private void Window_Loaded(object sender, RoutedEventArgs e) { NewLibrary.ItemsSource = from c in db.Components select c; } However, there is a problem. When the code is executed, it displays the object from the database (as the ItemSource property is set to the object from the database) and not the images. It does not use the template. When I use the static images source it works in the right way I found out that I need to override the PrepareContainerForItemOverride method.But I don't know how to add the template to it. Thanks a lot for any comments. Additional Information Here is the ControlTemplate for ToolboxItem: <ControlTemplate TargetType="{x:Type s:ToolboxItem}"> <Grid> <Rectangle Name="Border" StrokeThickness="1" StrokeDashArray="2" Fill="Transparent" SnapsToDevicePixels="true" /> <ContentPresenter Content="{TemplateBinding ContentControl.Content}" Margin="{TemplateBinding Padding}" SnapsToDevicePixels="{TemplateBinding UIElement.SnapsToDevicePixels}" /> </Grid> <ControlTemplate.Triggers> <Trigger Property="IsMouseOver" Value="true"> <Setter TargetName="Border" Property="Stroke" Value="Gray" /> </Trigger> </ControlTemplate.Triggers> </ControlTemplate>

  • Releasing the keyboard stops shake events. Why?

    - by Moshe
    1) How do I make a UITextField resign the keyboard and hide it? The keyboard is in a dynamically created subview whose superview looks for shake events. Resigning first responder seems to break the shake event handler. 2) how do you make the view holding the keyboard transparent, like see through glass? I have seen this done before. This part has been taken care of thanks guys. As always, code samples are appreciated. I've added my own to help explain the problem. EDIT: Basically, - (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event; gets called in my main view controller to handle shaking. When a user taps on the "edit" icon (a pen, in the bottom of the screen - not the traditional UINavigationBar edit button), the main view adds a subview to itself and animates it on to the screen using a custom animation. This subview contains a UINavigationController which holds a UITableView. The UITableView, when a cell is tapped on, loads a subview into itself. This second subview is the culprit. For some reason, a UITextField in this second subview is causing problems. When a user taps on the view, the main view will not respond to shakes unless the UITextField is active (in editing mode?). Additional info: My Motion Event Handler: - (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event { NSLog(@"%@", [event description]); SystemSoundID SoundID; NSString *soundFile = [[NSBundle mainBundle] pathForResource:@"shake" ofType:@"aif"]; AudioServicesCreateSystemSoundID((CFURLRef)[NSURL fileURLWithPath:soundFile], &SoundID); AudioServicesPlayAlertSound(SoundID); [self genRandom:TRUE]; } The genRandom: Method: /* Generate random label and apply it */ -(void)genRandom:(BOOL)deviceWasShaken{ if(deviceWasShaken == TRUE){ decisionText.text = [NSString stringWithFormat: (@"%@", [shakeReplies objectAtIndex:(arc4random() % [shakeReplies count])])]; }else{ SystemSoundID SoundID; NSString *soundFile = [[NSBundle mainBundle] pathForResource:@"string" ofType:@"aif"]; AudioServicesCreateSystemSoundID((CFURLRef)[NSURL fileURLWithPath:soundFile], &SoundID); AudioServicesPlayAlertSound(SoundID); decisionText.text = [NSString stringWithFormat: (@"%@", [pokeReplies objectAtIndex:(arc4random() % [pokeReplies count])])]; } } shakeReplies and pokeReplies are both NSArrays of strings. One is used for when a certain part of the screen is poked and one is for when the device is shaken. The app will randomly choose a string from the NSArray and display onscreen. For those of you who work graphically, here is a diagram of the view hierarchy: Root View -> UINavigationController -> UITableView -> Edit View -> Problem UITextfield

  • How to preserve sibling element position when one sibling is absolutely positioned?

    - by Casey
    In the snippet below, the child div is normally positioned until it is :hovered , when it becomes absolutely positioned. The reasoning behind this markup is to simulate a popup style in a limited environment where I can't use a <select> (among other limitations). When child is hovered, the sibling elements jump around, which is expected, as the contents of the block have changed. But how can I preserve their positioning? That is, what CSS can I add to prevent the siblings from jumping around when child is hovered. Javascript is also not allowed, so please no answers using JS. HTML: <div class="container"> <div class="child"> <span class="d4"></span> <label><input type="radio" name="radio" value="1"/>One</label> <label><input type="radio" name="radio" value="2"/>Two</label> </div> <input type="text" name="sibling"/> <button name="sibling2">Button</button> </div> CSS: .container, .child, button { display:inline-block; } .child { vertical-align: middle; width: 35px; height: 35px; } .child:hover { background: gray; position:absolute; width: 100px; height: auto; } .child:hover > .d4 { display: none; } .child label { display:none; } .child:hover label { display: inline-block; } .d4 { background-position: -411px -1px; width: 35px; height: 35px; background-image: url("https://i.imgur.com/zkgyBOi.png"); background-repeat: no-repeat; color: transparent; display: inline-block; } Here's a fiddle: http://jsfiddle.net/cpctZ/1/

  • Wordpress pages address rewrite

    - by kemp
    UPDATE I tried using the internal wordpress rewrite. What I have to do is an address like this: http://example.com/galleria/artist-name sent to the gallery.php page with a variable containing the artist-name. I used these rules as per Wordpress' documentation: // REWRITE RULES (per gallery) {{{ add_filter('rewrite_rules_array','wp_insertMyRewriteRules'); add_filter('query_vars','wp_insertMyRewriteQueryVars'); add_filter('init','flushRules'); // Remember to flush_rules() when adding rules function flushRules(){ global $wp_rewrite; $wp_rewrite->flush_rules(); } // Adding a new rule function wp_insertMyRewriteRules($rules) { $newrules = array(); $newrules['(galleria)/(.*)$'] = 'index.php?pagename=gallery&galleryname=$matches[2]'; return $newrules + $rules; } // Adding the id var so that WP recognizes it function wp_insertMyRewriteQueryVars($vars) { array_push($vars, 'galleryname'); return $vars; } what's weird now is that on my local wordpress test install, that works fine: the gallery page is called and the galleryname variable is passed. On the real site, on the other hand, the initial URL is accepted (as in it doesn't go into a 404) BUT it changes to http://example.com/gallery (I mean it actually changes in the browser's address bar) and the variable is not defined in gallery.php. Any idea what could possibly cause this different behavior? Alternatively, any other way I couldn't think of which could achieve the same effect described in the first three lines is perfectly fine. Old question What I need to do is rewriting this address: (1) http://localhost/wordpress/fake/text-value to (2) http://localhost/wordpress/gallery?somevar=text-value Notes: the remapping must be transparent: the user always has to see address (1) gallery is a permalink to a wordpress page, not a real address I basically need to rewrite the address first (to modify it) and then feed it back to mod rewrite again (to let wordpress parse it its own way). Problems if I simply do RewriteRule ^fake$ http://localhost/wordpress/gallery [L] it works but the address in the browser changes, which is no good, if I do RewriteRule ^fake$ /wordpress/gallery [L] I get a 404. I tried different flags instead of [L] but to no avail. How can I get this to work? EDIT: full .htaccess # BEGIN WordPress <IfModule mod_rewrite.c> RewriteEngine On RewriteRule ^fake$ /wordpress/gallery [R] RewriteBase /wordpress/ RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /wordpress/index.php [L] </IfModule> # END WordPress

  • Change user control appearance based on state

    - by John
    I have a user control that consists of four overlapping items: 2 rectangles, an ellipse and a lable <UserControl x:Class="UserControl" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Width="50.1" Height="45.424" Background="Transparent" FontSize="24"> <Grid> <Grid.RowDefinitions> <RowDefinition Height="3.303*" /> <RowDefinition Height="40*" /> <RowDefinition Height="2.121*" /> </Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition Width="5.344*" /> <ColumnDefinition Width="40.075*" /> <ColumnDefinition Width="4.663*" /> </Grid.ColumnDefinitions> <Rectangle Name="Rectangle1" RadiusX="5" RadiusY="5" Fill="DarkGray" Grid.ColumnSpan="3" Grid.RowSpan="3" /> <Ellipse Name="ellipse1" Fill="{Binding State}" Margin="0.016,0.001,4.663,0" Grid.Row="1" Grid.Column="1" Grid.ColumnSpan="2" Stroke="Black" IsEnabled="True" Panel.ZIndex="2" /> <Label Name="lblNumber" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" Foreground="White" FontWeight="Bold" FontSize="24" Grid.Column="1" Grid.Row="1" Padding="0" Panel.ZIndex="3">9</Label> <Rectangle Grid.Column="1" Grid.Row="1" Margin="0.091,0,4.663,0" Fill="Blue" Name="rectangle2" Stroke="Black" Grid.ColumnSpan="2" Panel.ZIndex="1" /> </Grid> Here is my business object that I want to control the state of my user control: Imports System.Data Imports System.ComponentModel Public Class BusinessObject Implements INotifyPropertyChanged 'Public logger As log4net.ILog Public Event PropertyChanged As PropertyChangedEventHandler Implements INotifyPropertyChanged.PropertyChanged Private _state As States Public Enum States State1 State2 State3 End Enum Public Property State() As States Get Return _state End Get Set(ByVal value As States) If (value <> _state) Then _state = value RaiseEvent PropertyChanged(Me, New PropertyChangedEventArgs("State")) End If End Set End Property Protected Sub OnPropertyChanged(ByVal name As String) RaiseEvent PropertyChanged(Me, New PropertyChangedEventArgs(name)) End Sub I want to be able to change the state of a business object in the code behind and have that change the colors of multiple shapes in my usercontrol. I'm not sure about how to do the binding. I set the datacontext of the user control in the code behind but not sure if that's right. I'm new to WPF and programming in general and I'm stuck on where to go from here. Any recommendations would be greatly appreciated!!

  • Resize AIR app window while dragging

    - by matt lohkamp
    So I've noticed Windows 7 has a disturbing tendency to prevent you from dragging the title bar of windows off the top of the screen. If you try - in this case, using an air app with a draggable area at the bottom of the window, allowing you to push the top of the window up past the screen - it just kicks the window back down far enough that the title bar is at the top of what it considers the 'visible area.' One solution would be to resize the app window as it moves, so that the title bar is always where windows wants it. How would you resize the window while you're dragging it, though? Would you do it like this? dragHitArea.addEventListener(MouseEvent.MOUSE_DOWN, function(e:MouseEvent):void{ stage.nativeWindow.height += 50; stage.nativeWindow.startMove(); stage.nativeWindow.height -= 50; }); see what's going on there? When I click, I'm doing startMove(), which is hooking into the OS' function for dragging a window around. I'm also increasing and decreasing the height of the window by 50 pixels - which should give me no net increase, right? Wrong - the first '.height +=' gets executed, but the '.height -=' after the .startMove() never runs. Why? update - If you're curious, I'm programming an air widget with fly-out menus which expand rightwards and upwards - and since those element can only be displayed within the boundaries of the application window itself (even though the window is set to be chromeless and transparent) I have to expand the application's borders to include the area that the menu 'pops up' into. In the extreme case, with the widget positioned bottom left, and the menus expanded completely across to the right side and top edge of the screen, the application area could very well cover the entire desktop. The problem is, when it's expanded like this, if the user drags it up and to the right, it causes the 'title bar' area of the application window to move above the top edge of the desktop area, where it would normally be unreachable; and Windows automatically re-positions the window back below that edge once the .startMove() operation is completed. So what I want to do is continually resize the height of the application so that the visual effect will be the same for the user, but for the benefit of the operating system the window's title bar will never be above that top boundary of the desktop area.

  • CSS Z-Index with Gradient Background

    - by Jona
    I'm making a small webpage where the I would like the top banner with some text to remain on top, as such: HTML: <div id = "topBanner"> <h1>Some Text</h1> </div> CSS: #topBanner{ position:fixed; background-color: #CCCCCC; width: 100%; height:200px; top:0; left:0; z-index:900; background: -moz-linear-gradient(top, rgba(204,204,204,0.65) 0%, rgba(204,204,204,0.44) 32%, rgba(204,204,204,0.12) 82%, rgba(204,204,204,0) 100%); /* FF3.6+ */ background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,rgba(204,204,204,0.65)), color-stop(32%,rgba(204,204,204,0.44)), color-stop(82%,rgba(204,204,204,0.12)), color-stop(100%,rgba(204,204,204,0))); /* Chrome,Safari4+ */ background: -webkit-linear-gradient(top, rgba(204,204,204,0.65) 0%,rgba(204,204,204,0.44) 32%,rgba(204,204,204,0.12) 82%,rgba(204,204,204,0) 100%); /* Chrome10+,Safari5.1+ */ background: -o-linear-gradient(top, rgba(204,204,204,0.65) 0%,rgba(204,204,204,0.44) 32%,rgba(204,204,204,0.12) 82%,rgba(204,204,204,0) 100%); /* Opera 11.10+ */ background: -ms-linear-gradient(top, rgba(204,204,204,0.65) 0%,rgba(204,204,204,0.44) 32%,rgba(204,204,204,0.12) 82%,rgba(204,204,204,0) 100%); /* IE10+ */ background: linear-gradient(to bottom, rgba(204,204,204,0.65) 0%,rgba(204,204,204,0.44) 32%,rgba(204,204,204,0.12) 82%,rgba(204,204,204,0) 100%); /* W3C */ filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#a6cccccc', endColorstr='#00cccccc',GradientType=0 ); /* IE6-9 */ } /*WebPage Header*/ h1{ font-size:3em; color:blue; text-shadow:#CCCCCC 2px 2px 2px, #000 0 -1px 2px; position: absolute; width: 570px; left:50%; right:50%; line-height:20px; margin-left: -285px; z-index:999; } The z-index works fine, except that because I'm using a gradient any time I scroll down the elements behind the banner are still visible, albeit somewhat transparent. Is there any way to make them total invisible? i.e., what I'm trying to do is make it as though the banner is a solid color, even though it's a gradient. Thanks in advance for any help!

  • Any thoughts on how to create a true 'punch-out' area in a Sprite?

    - by rhtx
    I've been working on this for awhile, now. You might also call it a 'reverse mask', or an 'inverse mask'. Basically, I'm creating a view window within a display object. I need to allow objects on the stage that are under the window to be able to interact with the mouse. This is similar to a WPF question: http://stackoverflow.com/questions/740994/use-wpf-object-to-punch-hole-in-another, which has a much shorter write-up. I've got a Class called PunchOutShield, which creates a Sprite that covers the stage (or over some desired area). The Sprite's Graphics object is filled using the color and transparency of Flex's modal screen. The result is a screen that looks like the screen which appears behind a modal PopUp. PunchOutShield has a method called punch, which takes two arguments - the first is a Shape object, which defines the shape of the punch-through area; the second is a Point object, which indicates where to position the punch-through area. It took some experimenting, but I found that I can successfully create a punch-out area (i.e. - the modal screen does not display within the bounds of the given Shape). To do this, I set cacheAsBitmap to true on the Sprite that is used to create the modal screen, and also on the Shape object, which is added to the modal screen Sprite's displayList. If I set the blend mode of the Shape to ERASE, a completely transparent area is created in the modal screen. So far, great. The problem is that Shape does not subclass InteractiveObject, so there is no way to set mouseEnabled = false on it. And so, it prevents interaction between the mouse and any objects that are visible through the punch-out area. On top of that, InteractiveObject isn't available to look at, so I can't see if there is a way to borrow what it's doing to provide the mouseEnabled functionality and apply it to a subclass of Shape. I've tried using another Sprite object, rather than a Shape object, but the blending doesn't work out correctly. I'm not sure why there is a difference, but the Shape object seems to somehow combine with the parenting Sprite, allowing the ERASE blendMode to effect the desired punch-out visual appearance. It wouldn't be the end of the world if I had to draw up the screen with a series of rectangles so that the punch-out area was just simply not drawn, but that approach won't work if the punch-out area is complex. Or round. Any thoughts on this approach, or on an alternative approach?

  • What makes a Winform position initially stale?

    - by msorens
    The code below demonstrates a very simple problem; I am hoping that I am just missing a setting that someone might be able to reveal. Goal (1) Launch main winform (MainForm). (2) Press button to display secondary winform (ShadowForm) that is semi-transparent and should exactly overlay MainForm. What Actually Happens Scenario 1: Launch main winform then press button: ShadowForm displays with correct size but incorrect location, lower and to the right (as if it was cascaded). Press button to close ShadowForm again. Press button once more to reopen ShadowForm and now it is in the correct position, covering MainForm. Scenario 2: Launch main winform, move it around, then press button: ShadowForm displays with correct size but incorrect location (where the MainForm was before moving it). Press button to close; press again to reopen and now ShadowForm is in the correct position. using System; using System.Windows.Forms; namespace LocationTest { static class Program { static void Main() { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(new MainForm()); } } public class MainForm : Form { ShadowForm shadowForm = new ShadowForm(); Button button1 = new Button(); System.ComponentModel.IContainer components = null; public MainForm() { this.SuspendLayout(); this.button1.Location = new System.Drawing.Point(102, 44); this.button1.Size = new System.Drawing.Size(75, 23); this.button1.Text = "button1"; this.button1.Click += new System.EventHandler(this.button1_Click); this.ClientSize = new System.Drawing.Size(292, 266); this.Controls.Add(this.button1); this.ResumeLayout(false); } private void button1_Click(object sender, EventArgs e) { if (shadowForm.Visible) { shadowForm.Hide(); } else { shadowForm.Size = Size; // this always works shadowForm.Location = Location; // this fails first time, but works second time! shadowForm.Show(); } } protected override void Dispose(bool disposing) { if (disposing && (components != null)) { components.Dispose(); } base.Dispose(disposing); } } public class ShadowForm : Form { private System.ComponentModel.IContainer components = null; public ShadowForm() { this.SuspendLayout(); this.BackColor = System.Drawing.Color.Black; this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None; this.Opacity = 0.5; this.Click += new System.EventHandler(this.ShadowForm_Click); this.ResumeLayout(false); } private void ShadowForm_Click(object sender, EventArgs e) { Hide(); } protected override void Dispose(bool disposing) { if (disposing && (components != null)) { components.Dispose(); } base.Dispose(disposing); } } }

    Hi I have a code in windows application now i am trying to implement in web Application but it is showimg that it ths no cursor class (System.Windows.Forms.Cursor )so..wat is the equivalent in web application. Here is my code private void btnGo_Click(System.Object sender, System.EventArgs e) { this.Cursor = Cursors.WaitCursor; Application.DoEvents(); // Load the images. Bitmap bm1 = (Bitmap) (Image.FromFile(txtFile1.Text)); Bitmap bm2 = (Bitmap) (Image.FromFile(txtFile2.Text)); // Make a difference image. int wid = Math.Min(bm1.Width, bm2.Width); int hgt = Math.Min(bm1.Height, bm2.Height); Bitmap bm3 = new Bitmap(wid, hgt); // Create the difference image. bool are_identical = true; int r1; int g1; int b1; int r2; int g2; int b2; int r3; int g3; int b3; Color eq_color = Color.White; Color ne_color = Color.Transparent; for (int x = 0; x <= wid - 1; x++) { for (int y = 0; y <= hgt - 1; y++) { if (bm1.GetPixel(x, y).Equals(bm2.GetPixel(x, y))) { bm3.SetPixel(x, y, eq_color); } else { bm1.SetPixel(x, y, ne_color); are_identical = false; } } } // Display the result. picResult.Image = bm1; Bitmap Logo = new Bitmap(picResult.Image); Logo.MakeTransparent(Logo.GetPixel(1, 1)); picResult.Image = (Image)Logo; this.Cursor = Cursors.Default; if ((bm1.Width != bm2.Width) || (bm1.Height != bm2.Height)) { are_identical = false; } if (are_identical) { MessageBox.Show("The images are identical"); } else { MessageBox.Show("The images are different"); } //bm1.Dispose() // bm2.Dispose() }

  • iPhone: Create a single UIView from multiple clicks

    - by Cuzog
    I'm making a partial overlay modal in my app with the code from “Semi-Modal (Transparent) Dialogs on the iPhone” at ramin.firoozye.com. In doing so, the button that calls the modal is still visible and clickable. I will hide this button when the modal spawns, but I want to be sure if the user clicks very quickly twice, a new modal doesn't come up for each click. What is the best way to check that the modal doesn't already exist when calling it from the button click? You can download the test project here. For those that don't have xcode, the relevant functions are below: I call forth the modal on button click with this: - (IBAction)displayModal:(id)sender { ModalViewController *modalController = [[ModalViewController alloc] initWithNibName:@"ModalViewController" bundle:nil]; modalController.view.frame = CGRectOffset(modalController.view.frame, 0, 230); [self showModal:modalController.view]; } Then use this function to animate the custom modal over the current view: - (void)showModal:(UIView*) modalView { UIWindow* mainWindow = (((TestAppDelegate*) [UIApplication sharedApplication].delegate).window); CGPoint middleCenter = modalView.center; CGSize offSize = [UIScreen mainScreen].bounds.size; CGPoint offScreenCenter = CGPointMake(offSize.width / 2.0, offSize.height * 1.5); modalView.center = offScreenCenter; // we start off-screen [mainWindow addSubview:modalView]; // Show it with a transition effect [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:0.4]; // animation duration in seconds modalView.center = middleCenter; [UIView commitAnimations]; } Then I dismiss the modal on button click with this: - (IBAction)dismissModal:(id)sender { [self hideModal:self.view]; } And then use these functions to animate the modal offscreen and clean itself up: - (void)hideModal:(UIView*) modalView { CGSize offSize = [UIScreen mainScreen].bounds.size; CGPoint offScreenCenter = CGPointMake(offSize.width / 2.0, offSize.height * 1.5); [UIView beginAnimations:nil context:modalView]; [UIView setAnimationDuration:0.7]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(hideModalEnded:finished:context:)]; modalView.center = offScreenCenter; [UIView commitAnimations]; } - (void)hideModalEnded:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context { UIView* modalView = (UIView *)context; [modalView removeFromSuperview]; [self release]; } Any help is greatly appreciated!

  • sub menu border calls onmouseout event

    - by insanepaul
    I've created a simple menu and submenu with tags(not allowed to use ul elements). To access the submenu the user hovers their mouse over the menu item. I use the onmouseover and onmouseout events to either show or hide the sub menu depending on which item is selected. A pipe (|) is used to seperate each submenu item and this is what is causing me problems. When a user hovers their mouse above the pipe character the subMenu div calls the onmouseout event which is not what I want. So I added padding around the pipe character and a minus margin so that there were no gaps between the pipe character and the other elements. This worked for all browsers including IE8. But in IE7 (I haven't tested IE6 yet) the submenu div calls the onmouseout event when I touch the top bit of either the left or right border of the pipe character span element. <div id="subMenu" onmouseout="hideSubMenu()" > <div id="opinionSubMenu" onmouseover="showOpinionSubMenu()"> <a id="Blogs" href="HTMLNew.htm">BLOGS</a> <span class="SubMenuDelimiter">|</span> <a id="Comments" href="HTMLNew.htm">COMMENTS</a> <span class="SubMenuDelimiter">|</span> <a id="Views" href="HTMLNew.htm">VIEWS</a> </div> <div id="learningSubMenu" onmouseover="showLearningSubMenu()"> <a id="Articles" href="HTMLNew.htm">ARTICLES</a> <span class="SubMenuDelimiter">|</span> <a id="CoursesCases" href="HTMLNew.htm">COURSES & CASES</a> <span class="SubMenuDelimiter">|</span> <a id="PracticeImpact" href="HTMLNew.htm">PRACTICE IMPACT</a> </div> </div> This is my css class #subMenu{ padding:10px 0px; background-color:#F58F2D; font-weight:normal; text-decoration:none; font-family:Lucida Sans Unicode; font-size:14px; float:left; width:100%; display:none;} #Blogs, #Comments, #Views, #Articles { padding:10px 5px; background:none repeat scroll 0 0 transparent; color:#000000; font-weight:normal; text-decoration:none; border:solid 1px black;} #Blogs:hover, #Comments:hover, #Views:hover, #Articles:hover{ color:#ffffff; text-decoration:none;} .SubMenuDelimiter{ padding:10px 5px; margin:10px -5px;}

  • How can I run an android frame animation without it skewing?

    - by GameDev123
    I have a small state machine that runs a series of frame by frame animations in an ImageView, in a nested hierarchy of layouts. There is more than adequate space to display each frame of the animation. Each frame of the animation is cropped to fit the minimum amount of area, in order to save memory. If a frame only contains 50x50 worth of pixels then the png is 50x50. There is no transparent padding to keep them the same size. The ImageView is directly within a RelativeLayout, and is anchored to the bottom left with some padding. The general idea being that the character in the animation performs some action, which results in individual frames of the animation growing or shrinking. The issue is that individual frames of animation are skewed, and there does not appear to be any way of preventing this. If I set the source of the imageview directly to one of the frames of animation, it displays fine in the layout manager. I have tried this with Adjust View Bounds set to true, false, and undefined. I have tried using the background and the src attribute of imageview to set the animation drawable, I have tried every configuration of layout manager and setting minimum/maximum size that I can think of, and it still stretches the character on various frames depending on the size of the source png. In essence, all I want to do is say "I want this ImageView to anchor in the bottom left and then display any frame that happens to be in it without stretching or skewing it in any way aside from that which occurred when the frame png's were loaded." Seems simple, but I have yet to come across any way of doing it. Here is the layout of the imageview as of my last test, I had to remove bits of the XML to get it to display but nothing pertinent: RelativeLayout android:orientation="horizontal" android:layout_above="@+id/MenuOptions" android:layout_width="fill_parent" android:id="@+id/AnimationLayout" android:clipChildren="false" android:minHeight="180dp" android:layout_height="fill_parent" android:layout_below="@+id/GameBarLayout" ImageView android:id="@+id/animatedImg" android:layout_height="wrap_content" android:layout_width="wrap_content" android:visibility="visible" android:baselineAlignBottom="true" android:minHeight="180dp" android:minWidth="200dp" android:adjustViewBounds="true" android:layout_alignParentBottom="true" android:paddingLeft="30dp" android:paddingBottom="10dp" android:src="@drawable/idle01"/ImageView /RelativeLayout Here is how an animation is set up: animationDrawable = new AnimationDrawable(); animationDrawable.addFrame(res.getDrawable(R.drawable.idle01), 16); animationDrawable.addFrame(res.getDrawable(R.drawable.idle02), 16); animationDrawable.addFrame(res.getDrawable(R.drawable.idle03), 16);

  • Is it a good or bad practice to call instance methods from a java constructor?

    - by Steve
    There are several different ways I can initialize complex objects (with injected dependencies and required set-up of injected members), are all seem reasonable, but have various advantages and disadvantages. I'll give a concrete example: final class MyClass { private final Dependency dependency; @Inject public MyClass(Dependency dependency) { this.dependency = dependency; dependency.addHandler(new Handler() { @Override void handle(int foo) { MyClass.this.doSomething(foo); } }); doSomething(0); } private void doSomething(int foo) { dependency.doSomethingElse(foo+1); } } As you can see, the constructor does 3 things, including calling an instance method. I've been told that calling instance methods from a constructor is unsafe because it circumvents the compiler's checks for uninitialized members. I.e. I could have called doSomething(0) before setting this.dependency, which would have compiled but not worked. What is the best way to refactor this? Make doSomething static and pass in the dependency explicitly? In my actual case I have three instance methods and three member fields that all depend on one another, so this seems like a lot of extra boilerplate to make all three of these static. Move the addHandler and doSomething into an @Inject public void init() method. While use with Guice will be transparent, it requires any manual construction to be sure to call init() or else the object won't be fully-functional if someone forgets. Also, this exposes more of the API, both of which seem like bad ideas. Wrap a nested class to keep the dependency to make sure it behaves properly without exposing additional API:class DependencyManager { private final Dependency dependency; public DependecyManager(Dependency dependency) { ... } public doSomething(int foo) { ... } } @Inject public MyClass(Dependency dependency) { DependencyManager manager = new DependencyManager(dependency); manager.doSomething(0); } This pulls instance methods out of all constructors, but generates an extra layer of classes, and when I already had inner and anonymous classes (e.g. that handler) it can become confusing - when I tried this I was told to move the DependencyManager to a separate file, which is also distasteful because it's now multiple files to do a single thing. So what is the preferred way to deal with this sort of situation?

  • Unable to get Stencil Buffer to work in iOS 4+ (5.0 works fine). [OpenGL ES 2.0]

    - by MurderDev
    So I am trying to use a stencil buffer in iOS for masking/clipping purposes. Do you guys have any idea why this code may not work? This is everything I have associated with Stencils. On iOS 4 I get a black screen. On iOS 5 I get exactly what I expect. The transparent areas of the image I drew in the stencil are the only areas being drawn later. Code is below. This is where I setup the frameBuffer, depth and stencil. In iOS the depth and stencil are combined. -(void)setupDepthBuffer { glGenRenderbuffers(1, &depthRenderBuffer); glBindRenderbuffer(GL_RENDERBUFFER, depthRenderBuffer); glRenderbufferStorage(GL_RENDERBUFFER, GL_DEPTH24_STENCIL8_OES, self.frame.size.width * [[UIScreen mainScreen] scale], self.frame.size.height * [[UIScreen mainScreen] scale]); } -(void)setupFrameBuffer { glGenFramebuffers(1, &frameBuffer); glBindFramebuffer(GL_FRAMEBUFFER, frameBuffer); glFramebufferRenderbuffer(GL_FRAMEBUFFER, GL_COLOR_ATTACHMENT0, GL_RENDERBUFFER, colorRenderBuffer); glFramebufferRenderbuffer(GL_FRAMEBUFFER, GL_DEPTH_ATTACHMENT, GL_RENDERBUFFER, depthRenderBuffer); glFramebufferRenderbuffer(GL_FRAMEBUFFER, GL_STENCIL_ATTACHMENT, GL_RENDERBUFFER, depthRenderBuffer); // Check the FBO. if(glCheckFramebufferStatus(GL_FRAMEBUFFER) != GL_FRAMEBUFFER_COMPLETE) { NSLog(@"Failure with framebuffer generation: %d", glCheckFramebufferStatus(GL_FRAMEBUFFER)); } } This is how I am setting up and drawing the stencil. (Shader code below.) glEnable(GL_STENCIL_TEST); glDisable(GL_DEPTH_TEST); glColorMask(GL_FALSE, GL_FALSE, GL_FALSE, GL_FALSE); glDepthMask(GL_FALSE); glStencilFunc(GL_ALWAYS, 1, -1); glStencilOp(GL_KEEP, GL_KEEP, GL_REPLACE); glColorMask(0, 0, 0, 0); glClear(GL_STENCIL_BUFFER_BIT); machineForeground.shader = [StencilEffect sharedInstance]; [machineForeground draw]; machineForeground.shader = [BasicEffect sharedInstance]; glDisable(GL_STENCIL_TEST); glColorMask(GL_TRUE, GL_TRUE, GL_TRUE, GL_TRUE); glDepthMask(GL_TRUE); Here is where I am using the stencil. glEnable(GL_STENCIL_TEST); glStencilOp(GL_KEEP, GL_KEEP, GL_KEEP); glStencilFunc(GL_EQUAL, 1, -1); ...Draw Stuff here glDisable(GL_STENCIL_TEST); Finally here is my fragment shader. varying lowp vec2 TexCoordOut; uniform sampler2D Texture; void main(void) { lowp vec4 color = texture2D(Texture, TexCoordOut); if(color.a < 0.1) gl_FragColor = color; else discard; }

  • Silverlight: Binding to a LayoutRoot value from within a DataTemplate

    - by Rosarch
    I have a DataTemplate for a ListBox, where I have several controls that bind to an item. I would also like to bind to a value on LayoutRoot.DataContext.

  • Making a Wrapper class for ActiveMQ

    - by DarthVader
    I want to make a Wrapper class for ActiveMQ which will have only send and get functions. I want to wrap them in a static class. Users can use this client and send, get messages to the activemq instance. I want this process to be transparent. There are two classes in this link My only handicap is, i need to this in c++ and not sure where to start. I havent used c++ for ages and now not sure how I can create this wrapper class. I m giving it a try as follows: // .h file #include <stdlib.h> #include <iostream> using namespace std; class ActiveMQWrapper { public: static void send(std::string message); static std::string get(); }; // .cpp file #include<string> #include<iostream> #include "ActiveMQWrapper.h" void ActiveMQWrapper::send(std::string message){ std::cout<<message; } std::string ActiveMQWrapper::get(){ return "test"; } // test file #include <string> #include <iostream> #include "ActiveMQWrapper.h" int main() { std::string foo ="test"; ActiveMQWrapper::send(foo); std::cout<<ActiveMQWrapper::get(); return 1; } When I added the following to .h file, hell breaks loose. Do you think I should seperate this impl to a factory and initialize and instance and return to the wrapper above? How do i deal with all the dependencies? private: Connection* connection; Session* session; Destination* destination; MessageProducer* producer; int numMessages; bool useTopic; bool sessionTransacted; std::string brokerURI; and the header files, i get several messages as errors, which complains about the path. How can i get this correct? I eventually want to build a Factory, get an instance and send or get the messages to the queue. is there a code sample i can look into to get this right? essential i want to use the functionality of only this producer and consumer. Edit: I understand there is no such thing as static class in C++ . This is my reference.

  • How to get ImageButton size within Android GridView?

    - by wufoo
    I'm subclassing ImageButton in order to draw lines on it and trying to figure out where the actual button coordinates are within my gridview. I am using onGlobalLayout to setup Top, Bottom, Right and Left, but these seem to be for the actual "square" within the grid, and not the actual button (see image). The purple lines are drawn in myImageButton.onDraw() using coords gathered from myImageButton.onGlobalLayout(). I thought these would be for the button, but they seem to be from something else. Not sure what. I'd like the purple lines to match the outline of the button so the lines I draw appear on the button and not just floating out in the LinearLayout somewhere. The light blue is the background color of the vertical LinearLayout holding the Textview (for the number) and myImageButton. Any way to get the actual button size? XML Layout: <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/lay_cellframe" android:layout_width="fill_parent" android:layout_height="fill_parent" > <LinearLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="fill_vertical|fill_horizontal" android:orientation="vertical" > <TextView android:id="@+id/tv_cell" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_margin="2dp" android:gravity="center" android:text="TextView" android:textSize="10sp" /> <com.example.icaltest2.myImageButton android:id="@+id/imageButton1" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_gravity="center" android:layout_margin="0dp" android:adjustViewBounds="false" android:background="@android:drawable/btn_default" android:scaleType="fitXY" android:src="@android:color/transparent" /> </LinearLayout> </FrameLayout> myImageButton.java public myImageButton (Context context, AttributeSet attrs) { super (context, attrs); mBounds = new Rect(); ViewTreeObserver vto = this.getViewTreeObserver (); vto.addOnGlobalLayoutListener (ogl); Log.d (TAG, "myImageButton"); } ...

  • How to make area outside of custom dialog view unclickable?

    - by portfoliobuilder
    I created a custom dialog (no, this is not dialog object) from an image and some other views. The conflict I am having with this custom dialog (again, this is a layout) is that the area around it closes the custom dialog. Is there a way I can make the outside area unclickable? I have tried wrapping the dialog view with a fullscreen frameLayout w/ transparent background, and then programmatically I set the frame attribute to setClickable(false). framelayout.setClickable(false); This does nothing. It still closes the dialog. Any other suggestions? Thank you in advance. This is my code: //used to disable background from closing the custom dialog private FrameLayout fl; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); setContentView(R.layout.layout_dialog); btnContinue = (Button) findViewById(R.id.btnContinue); btnContinue.setOnClickListener(this); fl.setClickable(false); //background suppose to lock } @Override public void onClick(View v) { // TODO Auto-generated method stub switch (v.getId()) { case R.id.Continue: finish(); } break; } } I also have another class for broadcastReceiver public class DialogManagerBroadcastReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { if(IdeaPlayInterfaceApplication.isActivityVisible()){ Intent i=new Intent(context,CustomDialogActivity.class); i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); context.startActivity(i); } } } The idea is that this custom dialog is not called at a specific instance, it is called every set amount of time no matter what I am doing in the application. I use an Intent and PendingIntent to repeatedly call this custom dialog over time. With something like this: cancelAlarmNotificationMonitoring(context); Calendar calendar = Calendar.getInstance(); Intent intent = new Intent(context, AlarmManagerBroadcastReceiver.class); PendingIntent pintent = PendingIntent.getBroadcast(context, 0, intent, 0); AlarmManager alarm = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE); alarm.setRepeating(AlarmManager.RTC_WAKEUP,calendar.getTimeInMillis()+ALARM_INTERVAL,ALARM_INTERVAL, pintent); Hopefully this is more clear now.
