• Set Window Properties based on Datatype of UserControl

  - by Kage

  I've got a simple window, that is container for various views. I've got a DataTemplate that shows the correct view based on whatever the window's MainViewModel property is set to. <DataTemplate DataType="{x:Type VM:StartupViewModel}"> <AdornerDecorator> <V:StartupView /> </AdornerDecorator> </DataTemplate> What I'd like to do is for certain views, change some properties on the base window, ie WindowStyle, ResizeMode etc. something like triggers, but on datatypes instead of property values? How could I accomplish this?

• Window screenshot using WinAPI

  - by Evl-ntnt

  How to make a screenshot of program window using WinAPI & C#? I sending WM_PAINT (0x000F) message to window, which I want to screenshot, wParam = HDChandle, but no screenshot in my picturebox. If I send a WM_CLOSE message, all waorking (target window closes). What I do wrong with WM_PAINT? May be HDC is not PictureBox (WinForms) component? P.S. GetLastError() == "" [DllImport("User32.dll")] public static extern Int64 SendMessage(IntPtr hWnd, uint Msg, IntPtr wParam, IntPtr lParam); ..... SendMessage(targetWindowHandle, 0x000F, pictureBox.Handle, IntPtr.Zero);

• How to remove maximize button in Mac OS X tool window in Qt

  - by Andy Brice

  I have a floating tool window. It works fine on Windows, but I can't get rid of the maximise button on Mac OS X. I have tried unsetting Qt::WindowMaximizeButtonHint and setting the window to fixed size. Nothing seems to work. MyWidget::MyWidget( QWidget* parent ) :QWidget( parent, Qt::Tool | Qt::CustomizeWindowHint ) { setupUi( this ); setFixedSize( sizeHint() ); // doesn't remove maximise button setWindowFlags( windowFlags() & ~Qt::WindowMaximizeButtonHint ); // doesn't remove maximise button } I don't want to use a frameless window. Any ideas? I am using Qt 4.4.

• javascript "this" points to Window object again

  - by terrani

  Hello, I asked a question on http://stackoverflow.com/questions/2719643/javascript-this-points-to-window-object regarding "this" points to Window object. here is source code var archive = function(){} archive.prototype.action = { test: function(callback){ callback(); }, test2: function(){ console.log(this); } } var oArchive = new archive(); oArchive.action.test(oArchive.action.test2); Tim Down wrote "but that function is then called using callback(), which means it is not called as a method and hence this is the global object". What are differences between calling a function by its actual name and callback() as shown on the source code? How does console.log(this) in test2 points to Window when it is inside archive.action???

• overlay text on some else's window - HUD

  - by taglius

  I am interested in writing an app that overlays a small heads up display (HUD) over another application, in VB.NET. Does anyone have an example of this? I will need to enumerate all open windows to find the window that I want, and then overlay some text in a specific position on the window. If the user moves that window, my text will need to follow. (I will probably be painting the text in a loop over and over). Edit: nobody answered my original query - I added C# to the keywords to see if any of gurus in that language might have an answer. thanks.

• JavaScript event window.onload not triggered

  - by Bernhard V

  Hi! I've got the following code in a website: window.onload = resize; window.onresize = resize; function resize(){ heightWithoutHeader = (window.innerHeight - 85) + "px"; document.getElementById("haupttabelle").style.height = heightWithoutHeader; document.getElementById("navBar").style.height = heightWithoutHeader; } The onresize works fine, but the onload event never fires. I've tried it in Firefox and Chrome and neither of them works. Thank you for your help and go for the reputation! ;D

• Open a chrome tab from delayed javascript window.open

  - by jettero

  When I window.open("http://blarg") in chrome, I get a new tab. If I delay the open, say using a jquery $(hrm).animate({},5e3,function(){window.open(url)); it opens the url in a new window with no status bar, etc — if I give it permission to pop-up that is. I'm looking for a way to get the instant behavior, that is, I wish to open a URL after an animation, but still in a new tab. I imagine I could get by with learning a way to instruct chrome to never ever open pop-ups and to always open them in tabs (I imagine there's a webkit setting, why it's not a built in is a mystery); but I'd rather try to find a way to do it from the javascript if possible. I somewhat doubt there's any way to do this though. I'm not aware of any javascript that's tab-aware.

  Hi all: I need 3 hash functions to hash strings of a sliding window moving over a text, to be used later to search within a bloom vector.

• maya "export all" window blocks my plugins script UI

  - by Hinchy

  I'm writing a custom File Translator for Maya which can export only (I have only declared the writer function). Currently having a problem with the MEL script which defines the plugin's options as a GUI. Currently I have a blank Maya scene, go to "file-export all". This creates the "File Export All" dialog, I then select my plugin exporter which runs my MEL script to create the bespoke options window. This new window is created behind the "File Export All" dialog and is not selectable! Do I have to place my export plugin specific options within the export all dialog rather than placing them in a separate window? Thanks for any links, tips or pointers you can provide.

• Increase the TCP receive window for a specific socket

  - by rursw1

  Hi, How to increase the TCP receive window for a specific socket? - I know how to do so for all the sockets by setting the registry key TcpWindowSize, but how do do that for a specific one? According to MSFT's documents, the way is Calling the Windows Sockets function setsockopt, which sets the receive window on a per-socket basis. But in setsockopt, it is mentioned about SO_RCVBUF : Specifies the total per-socket buffer space reserved for receives. This is unrelated to SO_MAX_MSG_SIZE and does not necessarily correspond to the size of the TCP receive window. So is it possible? How? Thanks.

• Check if window has focus

  - by user2536244

  I need to check if the user has windows on focus, I'm currently doing this: var isonfocus=true; window.onblur = function(){ isonfocus=false; } window.onfocus = function(){ isonfocus=true; } And whenever I need to check if the user has the windows on focus I just do if(isonfocus==true). Problem: if the user loses focus before the page loads, even if I do if(isonfocus==true) it will return true, even though the window is not on focus, and defining the var to false var isonfocus=false; will do the reverse. Can someone help me? Thanks.

• Call a JavaScript function in a Google Chrome window from a vb.net program

  - by user1464827

  I am having a real problem with this. I want to know if it is possible to run/call a javascript function in a Google Chrome web browser window from a VB.net application. The scenario is that i want to monitor the pc activity (which i know how to) and then if a certain event is met (for example, high ram usage) then it calls a JavaScript function in a Google Chrome web browser window so the website is updated. Sort of like a bridge. The only bit it need to know is the vb.net code for how to access a chrome window and invoke a javascript function if its possible. I assume i will need to use process handlers? Any help is appreciated.

• Window scrolling up when jquery dialog opens up

  - by zoom_pat277

  I am trying to open a modal jquery dialog using jquery 1.4 and jquery-ui-1.8rc3.custom.js The dialog opens up with no issues, in all browsers, but in IE 7 and 6, after the dialog opens up, the window scrolls itself to the buttom... I tried scrolling the window up back to the modal position but is very inconsistent. was using the following line of code after opening up the modal window.scrollTo($('selector').dialog('option', 'position')[0],$('selector').dialog('option', 'position')[1]); One weird thing I am noticing is that after I open the modal, the page becomes huge... as if some extra things adds up on the bottom .... and it eventually scrolls to the bottom. Any idea why this could be hapenning in html <div id="selector"> </div> in document.ready $('#selector').dialog({ bgiframe: true, autoOpen: false, width: 100, height: 100, modal: true, position: 'top' }); in js $('#selector').dialog('open');

• C# == operator in Immediate window behaves differently than at run-time

  - by Damiano

  Try the following in the Immediate window: object a1 = "a"; object a2 = "a"; a1==a2 // outputs false and you'll see that a1 == a2 outputs false. However, at runtime in either a window app or console, you'll get true: object t1 = "a"; object t2 = "a"; MessageBox.Show((t1 == t2).ToString()); // outputs true The runtime behavior is consistent with the definition for the == operator and strings. Does anybody know if this a bug in the Immediate window?

• jQuery: Post form to a modal window for previewing the entered data

  - by superUntitled

  I am looking for a way to use jQuery to allow a user to look at a modal window "preview" of a form before they submit the form to be saved. I have this working with javascript, the form is posted to a file named preview.php that iterates through the posted information. The script currently opens a new window. I would like instead to use jQuery to post the form to a modal window for previewing. Does anyone have any thoughts on how to do this? This is what I am currently using: <script language="JavaScript"> function preview(form) { form.target='_blank'; form.action='http://example.com/preview.php'; form.submit(); } </script> <input type="button" value="preview" onclick='preview(this.form)'>

• Why is this jquery dialog window not displaying?

  - by user338413

  I've got a form that is using jquery validation. When the user clicks the submit button, I've got some jquery that intercepts the submit and should display a dialog window asking the user to verify the information they entered on the form. This dialog window should only display if the form has validated. Here is my code: $('#form').submit(function(){ fillVerificationDialog(); /* This loads up the dialog with form data */ if (('#form').valid()){ $('verification_dialog').dialog('open'); return false; } }); My dialog window is not displaying. It just submits the form. And I've verified that the form is valid by using an alert that checks the value of $('#form').valid() If I remove the if statement and just have the line that opens the dialog, the dialog displays. However, it will display even if the form has errors which is what I'm trying to prevent.

• Wait window in a windows application

  - by Vinodtiru

  I basically need to show a wait window to the user. For this i have put two seperate window forms in the application. the first form is the main form with a button. The second one is a empty one with just a label text. On click of the button in Form1 i do the below Form2 f = new Form2(); f.Show(); Thread.Sleep(2000); f.Close(); My idea here is to show the wait window to the user for 2 second. But when i do this the Form 2 is not completely loaded because of which the label in it is blank. Please let me know your inputs on this.

• How does this JavaScript/JQuery Syntax work: (function( window, undefined ) { })(window)?

  - by DKinzer

  Have you ever taken a look under the hood at the JQuery 1.4 source code and noticed how it's encapsulated in the following way: (function( window, undefined ) { //All the JQuery code here ... })(window); I've read an article on JavaScript Namespacing and another one called "An Important Pair of Parens," so I know some about what's going on here. But I've never seen this particular syntax before. What is that undefined doing there? And why does window need to be passed and then appear at the end again?

• Normalized Device Coordinates to window coordinates

  - by okoman

  I just read some stuff about the theory behind 3d graphics. As I understand it, normalized device coordinates (NDC) are coordinates that describe a point in the interval from -1 to 1 on both the horizontal and vertical axis. On the other hand window coordinates describe a point somewhere between (0,0) and (width,height) of the window. So my formula to convert a point from the NDC coordinate system to the window system would be xwin = width + xndc * 0.5 * width ywin = height + ynfv * 0.5 * height The problem now is that in the OpenGL documentation for glViewport there is an other formula: xwin = ( xndc + 1 ) * width * 0.5 + x ywin = ( yndc + 1 ) * height * 0.5 + y Now I'm wondering what I am getting wrong. Especially I'm wondering what the additional "x" and "y" mean. Hope the question isn't too "not programming related", but I thought somehow it is related to graphics programming.

• How to keep a floating div centered on window resize (jQuery/CSS)

  - by Jimbo

  Is there a way (without binding to the window.resize event) to force a floating DIV to re-center itself when the browser window is resized? To help explain, I imagine the pseudocode would look something like: div.left = 50% - (div.width / 2) div.top = 50% - (div.height / 2) UPDATE My query having been answered below, I wanted to post the final outcome of my quest - a jQuery extension method allowing you to center any block element - hope it helps someone else too. jQuery.fn.center = function() { var container = $(window); var top = -this.height() / 2; var left = -this.width() / 2; return this.css('position', 'absolute').css({ 'margin-left': left + 'px', 'margin-top': top + 'px', 'left': '50%', 'top': '50%' }); } Usage: $('#mydiv').center();
