  • How the dispose() method works in C#.net?

    - by Shailesh Jaiswal
    I am developing smart device application in C#. It is a window application. In that application I have created the 4 to 5 window form. I am navigating in these forms from one form to another form by using linklabel control in C#. In linklabel_Click() method which I am using to navigate I am using the code form1.show() according to need. I read that form1.show() method automatically calls the form1.dispose() method on the from1. I also read that once we dispose the form it is removed from memory & we can not call it again. But in my application no one form gets disposed. I can see all the form even after calling the form1.show() method. when I use the link to go once again to from1 it does not get disposed. Is anything wrong in my concept? I am new in C#. Please tell me how the dispose method work in above context? What is the use of dispose method. It will be better if you describe me above issue with example.

  • HTML + CSS: fixed background image and body width/min-width (including fiddle)

    - by insertusernamehere
    So, here is my problem. I'm kinda stuck at the moment. I have a huge background image and content in the middle with those attributes: content is centered with margin auto and has a fixed width the content is related to the image (like the image is continued within the content) this relation is only horizontally (vertically scrolling moves everything around) This works actually fine (I'm only talking desktop, not mobile here :) ) with a position fixed on the huge background image. The problem that occurs is the following: When I resize the window to "smaller than the content" the background image gets it width from the body instead of the viewport. So the relation between content and image gets lost. Now I have this little JavaScript which does the trick, but this is of course some overhead I want to avoid: $(window).resize(function(){ img.css('left', (body.width() - img.width()) / 2 ); }); This works with a fixed positioned image, but can get a litty jumpy while calculating. I also tried things like that: <div id="test" style=" position: absolute; z-index: 0; top: 0; left: 0; width: 100%: height: 100%; background: transparent url(content/dummy/brand_backgroud_1600_1.jpg) no-repeat fixed center top; "></div> But this gets me back to my problem described. Is there any "script-less", elegant solution for this problem? UPDATE: now with Fiddle The one I'm trying to solve: http://jsfiddle.net/insertusernamehere/wPmrm/ The one with Javascript that works: http://jsfiddle.net/insertusernamehere/j5E8z/ NOTE The image size is always fixed. The image never gets scaled by the browser. In the JavaScript example it get's blown. So don't care about the size.

  • Runing bcdedit from python in Windows 2008 SP2

    - by Lee-Man
    I do not know windows well, so that may explain my dilemma ... I am trying to run bcdedit in Windows 2008R2 from Python 2.6. My Python routine to run a command looks like this: def run_program(cmd_str): """Run the specified command, returning its output as an array of lines""" dprint("run_program(%s): entering" % cmd_str) cmd_args = cmd_str.split() subproc = subprocess.Popen(cmd_args, stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=True) (outf, errf) = (subproc.stdout, subproc.stderr) olines = outf.readlines() elines = errf.readlines() if Options.debug: if elines: dprint('Error output:') for line in elines: dprint(line.rstrip()) if olines: dprint('Normal output:') for line in olines: dprint(line.rstrip()) errf.close() outf.close() res = subproc.wait() dprint('wait result=', res) return (res, olines) I call this function thusly: (res, o) = run_program('bcdedit /set {current} MSI forcedisable') This command works when I type it from a cmd window, and it works when I put it in a batch file and run it from a command window (as Administrator, of course). But when I run it from Python (as Administrator), Python claims it can't find the command, returning: bcdedit is not recognized as an internal or external command, operable program or batch file Also, if I trying running my batch file from Python (which works from the command line), it also fails. I've also tried it with the full path to bcdedit, with the same results. What is it about calling bcdedit from Python that makes it not found? Note that I can call other EXE files from Python, so I have some level of confidence that my Python code is sane ... but who knows. Any help would be most appreciated.

  • Fixed div once page is scrolled is flickering

    - by jasondavis
    I am trying to have an advertisement block/div that will be hald way down the page, once you scroll do the page to this point it will stick to the top. Here is a demo of what I am trying to do and the code I am using to do it with... http://jsfiddle.net/jasondavis/6vpA7/3/embedded/result/ In the demo it works perfectly how I am wanting it to be, however when I implement it on my live site, http://goo.gl/zuaZx it works but when you scroll down the div flickers in and out of view on each scroll or down key press. On my site to see the problem live it is the blokc on the right sidebar that says "Recommended Books" Here is the code I am using... $(document).ready( function() { $(window).scroll( function() { if ($(window).scrollTop() > $('#social-container').offset().top) $('#social').addClass('floating'); else $('#social').removeClass('floating'); } ); } );? css #social.floating { position: fixed; top: 0; }? My demo jsfiddle where it works correctly http://jsfiddle.net/jasondavis/6vpA7/3/ The only thing different on my live site is the div/id name is different. As you can see it is somewhat working on my live site except the flickering in and out of view as you scroll down the page. Anyone have any ideas why this would happen on my live site and not on my jsfiddle demo?

  • Dockable panes created in CChildFrame not visible the second time the app. starts.

    - by Nijenhuis
    Hi, I have created some dockable panes in CChildFrame::OnCreate() The first time i start the application they are shown. The second time i start the application they are created but the splitterwindows are completly against the sides of the clients area (bottom and right), so not visible. So i have to use the mouse to pull the splitters into the clientarea so that the dockable windows become visible again. If i do File-New in my app a new client window is created and showing the dockable windows as they should be. I Think this has something to do with saving the windows layout in the registry, because if i change SetRegistryKey(_T("61sakjgsajkdg")); in the CWinApp derived class of my app. and rerun they are shown again the first time. (but not the second time i restart the app). How can i save the layout of those dockable windows as well, so if i restart my app. they are visible ? Or else how do i prevent my app. of overwritting the window layout with the one previously saved. Something to do with LoadCustomState() and SaveCustomState() ?, i could no find any info on howto implement those methods. I have here a link to the demo project to demonstrate what i mean: http://www.4shared.com/file/237193472/c384f0f6/GUI60.html Could someone tell me how to show those dockable windows in my CChildFrame class the second time the app starts?

  • Is there a way to touch-enable scrolling in a WPF ScrollViewer?

    - by Brian Sullivan
    I'm trying to create a form in a WPF application that will allow the user to use iPhone-like gestures to scroll through the available fields. So, I've put all my form controls inside a StackPanel inside a ScrollViewer, and the scrollbar shows up as expected when there are too many elements to be shown on the screen. However, when I try to test this on my touch-enabled device, a panning gesture (placing a finger down on the surface and dragging it upward) does not move the viewable area down as I would expect. When I simply put a number of elements inside a ListView, the touch gestures work just fine. Is there any way to enable the same kind of behavior in a ScrollViewer? My window is structured like this: <Window x:Class="TestTouchScrolling.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525" Loaded="Window_Loaded"> <Grid> <ScrollViewer Name="viewer" VerticalScrollBarVisibility="Auto"> <StackPanel Name="panel"> <StackPanel Orientation="Horizontal"> <Label>Label 1:</Label> <TextBox Name="TextBox1"></TextBox> </StackPanel> <StackPanel Orientation="Horizontal"> <Label>Label 2:</Label> <TextBox Name="TextBox2"></TextBox> </StackPanel> <StackPanel Orientation="Horizontal"> <Label>Label 3:</Label> <TextBox Name="TextBox3"></TextBox> </StackPanel> <!-- Lots more like these --> </StackPanel> </ScrollViewer> </Grid>

  • How to use data receive event in Socket class?

    - by affan
    I have wrote a simple client that use TcpClient in dotnet to communicate. In order to wait for data messages from server i use a Read() thread that use blocking Read() call on socket. When i receive something i have to generate various events. These event occur in the worker thread and thus you cannot update a UI from it directly. Invoke() can be use but for end developer its difficult as my SDK would be use by users who may not use UI at all or use Presentation Framework. Presentation framework have different way of handling this. Invoke() on our test app as Microstation Addin take a lot of time at the moment. Microstation is single threaded application and call invoke on its thread is not good as it is always busy doing drawing and other stuff message take too long to process. I want my events to generate in same thread as UI so user donot have to go through the Dispatcher or Invoke. Now i want to know how can i be notified by socket when data arrive? Is there a build in callback for that. I like winsock style receive event without use of separate read thread. I also do not want to use window timer to for polling for data. I found IOControlCode.AsyncIO flag in IOControl() function which help says Enable notification for when data is waiting to be received. This value is equal to the Winsock 2 FIOASYNC constant. I could not found any example on how to use it to get notification. If i am write in MFC/Winsock we have to create a window of size(0,0) which was just used for listening for the data receive event or other socket events. But i don't know how to do that in dotnet application.

  • Including partial views when applying the Mode-View-ViewModel design pattern

    - by Filip Ekberg
    Consider that I have an application that just handles Messages and Users I want my Window to have a common Menu and an area where the current View is displayed. I can only work with either Messages or Users so I cannot work simultaniously with both Views. Therefore I have the following Controls MessageView.xaml UserView.xaml Just to make it a bit easier, both the Message Model and the User Model looks like this: Name Description Now, I have the following three ViewModels: MainWindowViewModel UsersViewModel MessagesViewModel The UsersViewModel and the MessagesViewModel both just fetch an ObserverableCollection<T> of its regarding Model which is bound in the corresponding View like this: <DataGrid ItemSource="{Binding ModelCollection}" /> The MainWindowViewModel hooks up two different Commands that have implemented ICommand that looks something like the following: public class ShowMessagesCommand : ICommand { private ViewModelBase ViewModel { get; set; } public ShowMessagesCommand (ViewModelBase viewModel) { ViewModel = viewModel; } public void Execute(object parameter) { var viewModel = new ProductsViewModel(); ViewModel.PartialViewModel = new MessageView { DataContext = viewModel }; } public bool CanExecute(object parameter) { return true; } public event EventHandler CanExecuteChanged; } And there is another one a like it that will show Users. Now this introduced ViewModelBase which only holds the following: public UIElement PartialViewModel { get { return (UIElement)GetValue(PartialViewModelProperty); } set { SetValue(PartialViewModelProperty, value); } } public static readonly DependencyProperty PartialViewModelProperty = DependencyProperty.Register("PartialViewModel", typeof(UIElement), typeof(ViewModelBase), new UIPropertyMetadata(null)); This dependency property is used in the MainWindow.xaml to display the User Control dynamicly like this: <UserControl Content="{Binding PartialViewModel}" /> There are also two buttons on this Window that fires the Commands: ShowMessagesCommand ShowUsersCommand And when these are fired, the UserControl changes because PartialViewModel is a dependency property. I want to know if this is bad practice? Should I not inject the User Control like this? Is there another "better" alternative that corresponds better with the design pattern? Or is this a nice way of including partial views?

  • How do I send a client-event asynchronously to a GtkWidget?

    - by fret
    I'm trying to send and receive a client-event using a GtkWidget on the win32 platform. The sending code looks like this: GtkWidget *Wnd; GdkNativeWindow Hnd = #ifdef WIN32 GDK_WINDOW_HWND(Wnd->window); #else GDK_WINDOW_XWINDOW(Wnd->window); #endif GdkEvent *Event = gdk_event_new(GDK_CLIENT_EVENT); // fill out Event params gdk_event_send_client_message(Event, Hnd); Receiving code looks like this: static gboolean MyClientEvent(GtkWidget *widget, GdkEventClient *ev, MyWnd *Wnd) { // breakpoint here... return TRUE; } GtkWidget *Wnd = gtk_window_new(GTK_WINDOW_TOPLEVEL); g_signal_connect( G_OBJECT(Wnd), "client-event", G_CALLBACK(MyClientEvent), this); gtk_widget_add_events(Wnd, GDK_ALL_EVENTS_MASK); I used Spy++ to see the message getting sent, so I know the sending side is ok. The receiving side however doesn't get the client-event. I was expecting my breakpoint in the callback to trigger... but it doesn't. I'm not even sure if a GtkWindow can receive a client-event... from past experience on X11 I thought it was pretty much the same as any other GtkWidget in that respect. Maybe on the win32 platform it's kinda different. But still I'd like to be able to get this working. I would like this to work with asynchronously, and in a thread-safe fashion, so that I can send events from worker threads up to the GUI thread.

  • c++ use of winmain()

    - by Jack
    Hi, I just started learning programming for windows in c++. I had this crazy image, that win32 programming is based on calling windows functions and sending parameters to and from them. Like, when you want to create window, you call some win32 function that handles windows GUI and say "Hi, please, create me new window, 100 x 100 px, with two buttons", and that GUI function says "Hi, no problem, when something happends, like user clicks one button, I will change this variable xy located in this location". So, I thought that it will be very similiar to console programming. But the very first instruction surprised me. I always thought that every program executes main() function first. So, when I launch app, windows stores some parameters on top of stack and run that application. So I assumed that initializing main() is just a c++ way to tell the compiler where the first instruction should be. But in win32 programming, there is function called winmain() which starts first. So I am little confused. I thought it´s rule that compiler must have main() to start with, that main just defines where ti start, like some start point identifier. So, please, why is there winmain() function instead of main()? When I thought that C++ programming is as logical as assembler, it confuses me once again.

  • css layout for footer at bottom with dynamic ajax content changing height of page

    - by m42
    [Update] I actually compromised on this problem for now by foregoing the fixed footer design. It seems that there is no problem with dynamic content moving the footer and resizing containers appropriately unless the footer is fixed to the browser bottom initially. I hope others will eventually provide a great solution that encompasses the best of both worlds. I spent all day trying to get the footer to move down the page to accommodate dynamically added (via ajax) content. I really need some pointers or links because I haven't found anything that helps. Basically: My site has some pages that begin with only a text box and a button so that the total height of the content area is only a few inches beneath the header area. I don't have any problem getting the sticky footer working so that the footer appears at the bottom of the browser window even when there is very little content on screen. That same css layout works fine for other pages that have content that extends beneath the browser window. The catch: The content has to be rendered and passed to the browser with the initial load. The Problem: Any content that is added to the page via AJAX after the initial load paints down the page correctly -- but the footer remains in its initial location. Please tell me there is a fix for this. I can't post the css until checking with my boss first - if possible - and if needed, I will later - but it's just a very basic version of the many sticky footer css solutions floating around the web. Thanks.

  • How to accurately resize nested elements with ems and font-size percentage?

    - by moonDogDog
    I have a carousel with textboxes for each image, and my client (who knows nothing about HTML) edits the textboxes using a WYSIWYG text editor. The resulting output is akin to your worst nightmares; something like: <div class="carousel-text-container"> <span style="font-size:18pt;"> <span style="font-weight:bold;"> Lorem <span style="font-size:15pt:">Dolor</span> </span> Ipsum <span style="font-size:19pt;"><span>&nbsp;<span>Sit</span>Amet</span> </span> </div> This site has to be displayed at 3 different sizes to accomodate smaller monitors, so I have been using CSS media queries to resize the site. Now I am having trouble resizing the text inside the textbox correctly. I have tried using jQuery.css to get the font size of each element in px, and then convert it to em. Then, by setting a font-size:x% sort of declaration on .carousel-text-container, I hoped that that would resize everything properly. Unfortunately, there seems to be a recursive nature with how font-size is applied in ems. That is, .example is not resized properly in the following because its parent is also influencing it <span style="font-size:2em;"> Something <span class="example" style="font-size:1.5em;">Else</span> </span> How can I resize everything reliably and precisely such I can achieve a true percentage of my original font size, margin, padding, line-height, etc. for all the children of .carousel-text-container?

  • WPF ToolBar Separator shrinks to nothing when inside a StackPanel

  • Can this auto-stretcing scenario be realized undex XHTML/CSS?

    - by Vilx-
    I want two horizontal areas in my webpage. The first one is the menu. It's on the top. Unfortunately I don't know its size, and it might change in response to user actions. Below the menu is the main area which should stretch at least as far as the bottom of the window (if there is little content) or beyond (if there is a lot of content. To illustrate with ASCII art: +----------------------------------------------------+ | This area resizes vertically depending on contents | +----------------------------------------------------+ | This area stretches to the bottom of the window, | | but can be even larger if necessary. Note: this | | should be a separate area because it will contain | | children with height:100% as well. | | | +----------------------------------------------------+ Can this be done? Can it be done with Javascript? Added: To put things in perspective and avoid confusion, think of it this way: the top menu is generated by myself, but the bottom area is an IFrame which I want to fill the rest of the page. This is what it eventually comes down to anyway in my case.

  • Modifying CSS class property values on the fly with JavaScript / jQuery

    - by JPN
    all. I've run into a unique situation that I have so far been unable to find a solution for: dynamically assigning a value to a CSS style. I know how to use jQuery to assign width, height, etc. to an element, but what I'm trying to do is actually change the value defined in the stylesheet so that the dynamically-created value can be assigned to multiple elements. What I'm building is a slideshow of images that occupy the full viewport, recalculating the image's width, height, and left properties on resize so that the image is always centered, favors width over height, except when the viewport is taller than it is wide (resizing does not reload the page, just fires a function to resize the image). I have successfully been able to get it to work on one image, and now I'm trying to determine the best way to assign those property values to all images in the slideshow without having to specify those three things individually for every image. Can the values of properties in a class be modified on the fly? I'm sure the answer is out there, I'm probably just not using the correct terminology in my searches. Hope I did a good job of describing the problem. TIA.

Daemon sends statuses and agent shows it with a progress indicator. When there are any data on socket, callback function begin to work and at this time I have to immediately show the new window with progress indicator and increase counter. //this function initiate the runloop for listening socket - (int) AcceptDaemonConnection:(ConnectionRef)conn { int err = 0; conn->fSockCF = CFSocketCreateWithNative(NULL, (CFSocketNativeHandle) conn->fSockFD, kCFSocketAcceptCallBack, ConnectionGotData, NULL); if (conn->fSockCF == NULL) err = EINVAL; if (err == 0) { conn->fRunLoopSource = CFSocketCreateRunLoopSource(NULL, conn->fSockCF, 0); if (conn->fRunLoopSource == NULL) err = EINVAL; else CFRunLoopAddSource(CFRunLoopGetCurrent(), conn->fRunLoopSource, kCFRunLoopDefaultMode); CFRelease(conn->fRunLoopSource); } return err; } // callback function void ConnectionGotData(CFSocketRef s, CFSocketCallBackType type, CFDataRef address, const void * data, void * info) { #pragma unused(s) #pragma unused(address) #pragma unused(info) assert(type == kCFSocketAcceptCallBack); assert( (int *) data != NULL ); assert( (*(int *) data) != -1 ); TStatusUpdate status; int nativeSocket = *(int *) data; status = [agg AcceptPacket:nativeSocket]; // [stWindow InitNewWindow] inside [agg SendUpdateStatus:status.percent]; } AcceptPacket function receives packet from the socket and trying to show new window with progress indicator. Corresponding function is called, but nothing happens... I think, that I have to make work the main application loop with interrupting CFSocket loop... Or send a notification? No idea....

    - by Cameron
    I have the following code to show how long a user has left before their session will expire, I am using WordPress. How can I do this? Thanks <script> var obj_Span; var n_Seconds = 0; var n_Minutes = 0; var n_Hours = 0; function F_ConvertNumberToString ( n_Num ) { var str_Num = String(n_Num); if ( str_Num.length < 2 ) str_Num = "0" + str_Num; return str_Num; } function F_CountDown () { if ( n_Hours == 0 && n_Minutes == 0 && n_Seconds == 0 ) { obj_Span.innerHTML = "(Sorry, your session has expired.)"; } else { if ( n_Seconds >= 0 ) n_Seconds --; if ( n_Seconds < 0 ) { n_Minutes --; n_Seconds = 59; } if ( n_Minutes >= 0 ) { window.setTimeout ( "F_CountDown()", 1000 ); } if ( n_Minutes < 0 ) { n_Hours --; n_Minutes = 59; window.setTimeout ( "F_CountDown()", 1000 ); } F_UpdateDisplay (); } } function F_UpdateDisplay ( ) { if ( document.getElementById ) { if (n_Hours > 0 ) obj_Span.innerHTML = "(Remaining " + F_ConvertNumberToString(n_Hours) + ":" + F_ConvertNumberToString(n_Minutes) + ":" + F_ConvertNumberToString(n_Seconds) + ")"; else obj_Span.innerHTML = "(Remaining " + F_ConvertNumberToString(n_Minutes) + ":" + F_ConvertNumberToString(n_Seconds) + ")"; } } function F_StartCountDown ( n_Session ) { obj_Span = document.getElementById ( "CountDown" ); n_Minutes = n_Session; n_Hours = Math.floor(n_Minutes/60); n_Minutes = n_Minutes - (60*n_Hours); F_CountDown (); } </script> <script> F_StartCountDown ( " code here... " ); </script> <span id="CountDown"></span>

  • WPF : Command routing for Keyboard shortcuts.

    - by Sprotty
    Basically I want to create a keyboard shortcut which is valid within the scope of a window, and not just enabled when focus is within the control that binds it. in more detail.... I have a window which has 3 controls a toolbar textbox Custom Control The toolbar has a button bound to the Command CustomCommands.CmdA and linked to 'Ctrl-T'. My Custom Control can process CmdA. When I run the app and click on my custom control CmdA is enabled and works fine. Also Ctrl-T cause the command to fire. However when I select the text box, my custom command CmdA becomes disabled. I can rectify this by setting the command target for CmdA's button. Now when I select the textBox, CmdA is still enabled. But the Keyboard shortcut Ctrl-T does nothing. Is there any easy way to change the scope of keyboard shortcuts? Or do I need to catch the keypress somewhere lower down, and work out which Command it relates to and route it myself (if so is there a framework within which to do this?) Many Thanks Simon
