  • How can I get Text property to initialize to the objects name at design time?

    - by cyclotis04
    When you add a label to the form from the toolbox, its text defaults to the item's name (label1, label2, etc). How can I make this happen with a custom control? So far, I have the following, which allows me to change the text through the property window: private string _text; [BrowsableAttribute(true)] public override string Text { get { return _text; } set { _text = value; lblID.Text = _text; } } Apparently the above code works as is, but I'm not sure why. Does Text default to the object's name automatically? The question still stands for other properties which don't override Text.

  • Access to a single pixel in C#

    - by Malki
    Hello, I'm working on a school project right now. It's meant to be a 3D editing software, (like a very minimized version of Maya). I have to write it in C#, using the 'Windows Application Project'. I intend to implement all the 3D stuff myself, from projections to shading. My question is, how can I get direct access to a single pixel in the C# windows application? I know I'm going to have a main view port in the window. But I haven't decided yet how it will be made. Is there a built in object that I can use, that will let me define the boundaries of the view port, and then paint each pixel individually? (I'm just shooting in the dark here, I don't know much about C#. I mostly program in C) Thanks, Malki.

  • I'm using the jQuery .scroll() function, why can't I override its effects with another function?

    - by Jason Rhodes
    I'm using the jQuery .scroll() function to make a certain element fade to 0.2 opacity. Since there is no native "scrollstop" indicator, I decided to make the element fade back to 1.0 opacity on hover. However, it doesn't work. Here's my code: $(document).ready(function() { $(window).scroll(function() { $("#navlist").animate({ opacity: 0.2 }, 2000); }); $("#navlist").hover( function() { $(this).animate({ opacity: 1 }, 500); }, function() { $(this).animate({ opacity: 1 }, 500); // just to be safe? } ); }); When I scroll, the #navlist element fades, but when you hover over it nothing happens. But if you refresh the page when you're half way down, the element automatically fades as soon as you refresh, before I've scrolled, and if you try to hover to fade it back in, nothing happens. Any thoughts?

Hyper link column is that: < toolkit:DataGridHyperlinkColumn Header="Path" Binding="{Binding path}" IsReadOnly="True" TargetName="{Binding Path=path}"

  • Prevent auto scrolling when clicking tab anchor

    - by JohnCrossy
    On my page I have some tabs that I've added some javascript so when they're clicked the page loads the tab's anchor URL instead of simply changing the view with AJAX, but I now want to stop the browser from auto scrolling to the anchor location. Having done some research, I'm pretty sure I just need to add a couple of lines so that when clicked it returns false or prevents default but, being a noob, I've no idea where to put them!?! I know it's cheeky, but if any answers could include the full script (ie. the below) with the solution, that way I'll understand better and hopefully learn some valuable lessons also :) Here's the code I'm using: jQuery( function() { jQuery('.ui-tabs').bind( 'tabsselect', function( e, ui ) { window.location.hash = ui.tab.hash }); });

  • Handling Messages in Console Apps/DLLs in C++ Win32

    - by vsimon
    I would like to have the ability to process Win32 messages in a console app and/or inside a standalone DLL. I have been able to do it in .NET with the following article and it works great in C# inside a console app and standalone DLL http://msdn.microsoft.com/en-us/magazine/cc163417.aspx Is there a way to do the equivalent with C/C++ Win32 APIs? I have tried doing RegisterClassEx(...) and CreateWindow(...) even passing in HWND_MESSAGE to hWndParent but the trouble is that after the "invisible" window is created messages are not being processed probably due to the lack of a message pump. Where would the message pump go if you had a DLL entry point? I have tried creating another thread in a DLL and put while(GetMesage(..)) there but that did not work either. Any ideas?

  • Build turns partially transparent image pixels black

    - by Sean O'Hollaren
    I'm very new to C# and I've run into a problem and haven't been able to solve it. I have a row of buttons that have .png images assigned to them. The images are in .png format to allow transparency, and smoothing the edges in GIMP leaves some semi-transparent pixels. I've set the Image List Toolbar (imglToolbar)'s properties to recognize "Transparent" as the designated color to show up as transparent. I'm working in Visual Studio 2005. The strange thing is that everything looks great when I'm viewing the Visual C# form preview window. The icons look exactly as they should. However, once I actually build the project, the buttons treat every semi-transparent pixel near the edge of the image as if it's black. It seems like it can't handle one that's both transparent and has color. Image of it via the Visual C# form editor: Image of what it looks like when built: Any ideas as to why this is happening?

  • Word on HTML document point.

    - by leolobato
    Hey guys, How can I figure out which word is at the point where the user tapped on a UIWebView? I am able to detect the CGPoint for the tap (subclassing UIWindow like this), and I can actually get the DOM element on that point using javascript. But I know very little of javascript and DOM to figure out how can I actually get which word the user tapped on. Is that possible? Here's what I have right now: int scrollPosition = [[webView stringByEvaluatingJavaScriptFromString:@"window.pageYOffset"] intValue]; NSString *js = [NSString stringWithFormat:@"document.elementFromPoint(%f, %f).tagName", point.x, point.y+scrollPosition]; NSString *value = [webView stringByEvaluatingJavaScriptFromString:js]; NSLog(@"element: %@", value);

  • Trouble adding success flag to onbeforeunload

    - by Dirty Bird Design
    having issues with onbeforeunload. I have a long form broken into segments via a jquery wizard plug in. I need to pop a confirm dialog if you hit back, refresh, close etc on any step but need it to NOT POP the confirm dialog on click of the submit button. had it working, or at least I thought, it doesn't now. <script type="text/javascript"> var okToSubmit = false; window.onbeforeunload = function() { document.getElementById('Register').onclick = function() { okToSubmit = true; }; if(!okToSubmit) return "Using the browsers back button will cause you to lose all form data. Please use the Next and Back buttons on the form"; }; </script> 'Register' is the submit button ID. Please help!

  • jquery animating different img widths

    - by romeozor
    Hi there, I've been searching for an answer for a long time with no avail, so it's time to ask. I'm trying to use .animate() to change the size of an image once clicked. The first state of the image would be a thumbnail size, which would animate to the image's original size, then to a thumbnail again. The problem is, not all the images have the same "original" size so I need a way to tell one generic function to switch to the current image's original size. This is my current code which loads on $(window).load: $('img[class=resize]').click(function (){ if ($(this).width() != 150) { $(this).animate({width: '150px'}, 400); } else { $(this).animate({width: ''}, 400); } }); Now this obviously doesn't work the way I want it, because .animate() thinks when I say width: '' I want to make the width = 0. Any suggestions how I should go about this?

  • How to override browser default download behavior for files?

    - by moha297
    Lots of times we have to download files from the net. In IE we get to see the ugly download progress bar. In firefox we get to see a pop-up window opening etc. However, I have never seen this being over ridden in any manner. Until recently on the site *thesixtyone DOT com* If we get to download a song free and click on the ok link to start the download we get a pop up to select location in the default style of windows. Then we see the progress bar as shown below. Any ideas on this? I am trying to see how these guys did this. you can see the image http://highwaves.files.wordpress.com/2010/04/61-download-bar.jpg

  • JavaFX InternalFrame or WindowNode

    - by user1493549
    I was looking for an InternalFrame for JavaFX. Apparently I it seems like there is no InternalFrame available. How does one create an MDI application with JavaFX? I have tried to simulate this behavior by using a custom Region that can be dragged around. Is that the way to go? What about typical window elements such as titlebar, possibility to resize etc. Do I have to implement that myself via custom controls? Thanks, miho

  • Rewriting a simple Pygame 2D drawing function in C++

    - by Dominic Bou-Samra
    I have a 2D list of vectors (say 20x20 / 400 points) and I am drawing these points on a screen like so: for row in grid: for point in row: pygame.draw.circle(window, white, (particle.x, particle.y), 2, 0) pygame.display.flip() #redraw the screen This works perfectly, however it's much slower then I expected. I want to rewrite this in C++ and hopefully learn some stuff (I am doing a unit on C++ atm, so it'll help) on the way. What's the easiest way to approach this? I have looked at Direct X, and have so far followed a bunch of tutorials and have drawn some rudimentary triangles. However I can't find a simple (draw point).

  • How do I create a WPF Dropdown panel

    - by Mitch
    I'd like to create a dropdown panel in WPF the acts like a ComboBox/Expander hybrid. I'm currently using an Expander but it pushes the the controls underneath it down when it expands. I simply want it to act like a ComboBox and overlay it's dropdown. I've looked at using Popups but they don't move with the underlying window if it's moved. So, I've concluded that the closest control to my needs is a ComboBox with allows me to put a Grid or StackPanel into its dropdown area. Any ideas how to achieve this?

  • Hashbytes comparison in stored proceduring not matching record

    - by Michael Itzoe
    The password field in my user table (SQL Server 2008) is encrypted using HASHBYTES on insertion. I have a stored procedure with parameters for the username and plain-text password which does a SELECT using that username and the password sent through HASHBYTES, then returns the user record if it finds a match. The SP is always returning an empty recordset, but if I copy and paste just the SELECT from the SP to a new query window, it returns the matched record. There're no other statements in the SP. I'm missing something here; what is it?

  • C# StandardInput Sending Mofidiers

    - by Paul Oakham
    Hi All, We have some legacy software which depends on sending keystrokes to a DOS window and then scraping the screen. I am trying to re-create the software by redirecting the input and output streams of the process directly to my application. This part I have managed fine using: _Process = new Process(); { _Process.StartInfo.FileName = APPLICATION; _Process.StartInfo.RedirectStandardOutput = true; _Process.StartInfo.RedirectStandardInput = true; _Process.StartInfo.RedirectStandardError = true; _Process.StartInfo.UseShellExecute = false; _Process.StartInfo.CreateNoWindow = true; _Process.OutputDataReceived += new DataReceivedEventHandler(_Process_OutputDataReceived); _Process.ErrorDataReceived += new DataReceivedEventHandler(_Process_ErrorDataReceived); } My problem is I need to send some command modifiers such as Ctrl, ALT and Space as well as F1-12 to this process but am unsure how. I can send basic text and I receive response's fine. I just need to emulate these modifiers. Any help would be great, Cheers

  • SetParent() on a VB6 application from a C# app

    - by JD
    Aloha all! I am trying to use the win32 API to set the parent of an application to a panel in my C# application. I can get most applications to work... However I have one application which was written in VB6 which I am having problems with... When I inspect it using spy++ the application loads in 2 main forms 'ThunderRT6Main' and 'ThunderRT6MDIForm' both with the same title. I have found the handle of both of these and tried to call SetParent on them both but the window does nothing and does not move anywhere... Is there something funky I need to do when invoking SetParent() on a VB6 app?

  • CoreData and many NSArrayController

    - by unixo
    In my CoreData Application, I've an outline view on left of main window, acting as source list (like iTunes); on the right I display a proper view, based on outline selection. Each view has its components, such as table view, connected to array controller, owned by the specific view. Very often different views display same data, for example, a table view of the same entity. From a performance point of view, is better to have a single array controller per entity and share it between all views or does CoreData cache avoid memory waste?

  • Can I grant explicit Javascript methods to a different-host iframe?

    - by Matchu
    I'm thinking about a system in which I allow users to create Javascript-empowered widgets for other users to embed in their dashboard on my website. I'd like to limit these widgets fairly strictly, so each would exist as an iframe kept on its own unique hostname: the widget with ID #47 would be accessible at w47.widgets.example.com, for example. It would be helpful, for permission-granting dialogs and the like, to allow the widget to call very specific methods explicitly granted by the parent window, without authorizing the iframe to do whatever it likes with the parent frame on the user's behalf. Is it possible for a parent document to explicitly allow certain method calls to a child document on a different host?

  • Allowing pop-up's and downloads with flex

    I'm building an flex app that is basically a wrapper for a few websites.

  • iphone web app: open directions in external maps application

    - by munchybunch
    I've seen the answers for opening the Maps app in a native iPhone app, but is there any way to do this in a web app? I've tried changing window.location to http://maps.google.com/maps?q=cupertino for example, to no avail. I've tried using a simple anchor tag linked to http://maps.google.com/maps?q=cupertino, also to no avail. Has anyone gotten this to work before? I'm working on a map-heavy application, and I'd like to provide users with directions at the end. I figured it would be easiest to simply open it up in the Map application. Note: I'm currently testing with just the simulator, could that lead to problems? My iPhone is down for the count at the moment.
