  • Getting progress status out of a class library method

    - by Richard
    This app that I am doing uses a class library (if I dare call it that) to do the bulk of the work: 2 main methods in there (DoWork and UndoWork) use the other classes to achieve thier goal. Now that that works, I want to get out of the Console test enviroment and do a GUI. How would I get the status of say, the DoWork() method to update a progress bar? Should I multilate the class library (which currently works with the Console and Windows.Forms) to update? The problem with that is that I would surely have to make the class library use Window.Forms which will mess up the console testing apps (And there are lots of them - I tested all the way through, and then all together). Could you suggest some ideas, or places I can read up about ideas (the whole point of writing this this program is to learn, afer all)? Oh, by the way, suggestions like "foresight" or "planning" probably won't help here...(now, anywyay!) - But certainly will in future projects!

  • What parameters should I use in a Google Maps URL to go to a lat-lon?

    - by xpda
    I would like to produce a url for Google Maps that goes to a specific latitude and longitude. Now, I generate a url such as this: http://maps.google.com/maps?z=11&t=k&q=58 41.881N 152 31.324W The resulting map comes up with a round "A" balloon pointer, which seems to point to the nearest named object, and a green arrow, which points to the lat-lon. Sometimes, as in this example, the "A" pointer is centered and is far enough away that you cannot see the pointer to the lat-lon. (Zoom out to see both pointers in this example. The "A" pointer is in the center of Alaska, while the lat-long pointer is on Kodiak Island.) Are there some parameters I can use in the Google Maps URL that will produce a single pointer to a designated lat-lon? (This loads in a separate window. It is not embedded.)

  • Help! How to get the event handler with IE Dom interfaces?

    - by usfree74
    Hey Gurus, I am working to use IE Dom interface to automate IE page access. I am trying to get all event handlers defined in a page. I am using IHTMLElement object now for this purpose. If the html page defines "onclick=xxx", element.onclick returns the click handler. However, if an event handler is defined in javascript, element.onclick simply returns NULL. What's the right way to get the event handler then? Thanks, xin Below is an example that uses javascript to define event handler. $(document).ready(function(){ $("a").click(function(event){ $(this).hide("slow"); alert("Thanks for visiting!"); window.location="http://cnn.com"; }); }); jQuery

  • WPF: Turning off animations, data binding temporarly for invisible objects?;)

    - by TomTom
    I have a window that contains a tab control - basically multiple sheets with visualizations on them. The visualtizations are: possible very resource intensive during rendering relying on constant data updates to update their underlying models Obviously only one sheet can be visible every time ;) Anyone knows of a good way to turn off all visualization, animations, data binding for a control / panel and it's contained controls? If I would find a way to do that, I could simply turn off all the invisible sheets and reactivate them as needed. The models must be kept running - some of the visual stuff is pretty complex and really relies on constant data updates, and recalculating it when someone switches tabs would be too hard.

  • Swapping data binding in code

    - by Phil J Pearson
    I have two data-bound text boxes. One is bound to a string and the other to a number. The 'default' binding is set in XAML. Under some circumstances I need to reverse the bindings at runtime (the string is usually a prefix but sometimes it's a suffix). I have the following code in my view model, called when the window is loaded: Binding stringBinding = BindingOperations.GetBinding(view.seqLeft, TextBox.TextProperty); Binding numberBinding = BindingOperations.GetBinding(view.seqRight, TextBox.TextProperty); view.seqLeft.SetBinding(TextBlock.TextProperty, numberBinding); view.seqRight.SetBinding(TextBlock.TextProperty, stringBinding); After that the code loads the properties to which the binding refers. The problem is that the 'new' binding doesn't seem to work. What have I missed? Is there a better way?

  • Flowplayer RTMP streaming, mp4, Amazon Cloudfront and iPad/iPhone

    - by circey
    I've been working on a site where 2 video clips are streamed using Amazon Cloudfront and Flowplayer. You can see one video/page here: http://graemeclarkoration.org.au/gcorationp1.htm (works as a Highslide popup/modal window, hence the lack of adornment). While it works in all browsers and Android devices, I can't get it to work on an iPad or an iPhone; the page opens fine and the video box appears but the video never loads. Does anyone have any ideas how to fix or even why the video won't load? MTIA

  • jquery calendarpicker callback pass querystring

    - by user577318
    Trying to use this CalendarPicker source and docs here: http://bugsvoice.com/applications/bugsVoice/site/test/calendarPickerDemo.jsp I need to be able to pass the date selected as query string variable of "searchdate" and reload page also updating current date for calendarPicker with querystring date on page reload. This is what I have so far: jQuery(document).ready(function() { var calendarPicker = jQuery("#calendarpicker").calendarPicker({ monthNames:["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"], dayNames: ["Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat"], years:0, months:6, days:5, showDayArrows:true, callback:function(cal) { // Simple output to test calendar date change jQuery("#output").html("Selected date: " + cal.currentDate.getFullYear()+"-"+cal.currentDate.getMonth()+"-"+cal.currentDate.getDate() ); // Not working well since it also includes arrows from datepicker as selectors jQuery(".calDay").children().click(function() { window.location.href="mysite.com?searchdate="+cal.currentDate.getFullYear()+"-"+cal.currentDate.getMonth()+"-"+cal.currentDate.getDate(); }); } }); Any help greatly appreciated. Can this be done with ajax? I am attempting to update a table of events by datepicker.

  • Question about AJAX

    - by Doug
    function showHint(str) { if (window.XMLHttpRequest) { xmlhttp=new XMLHttpRequest(); } else { xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { document.getElementById("games").innerHTML=xmlhttp.responseText; } } xmlhttp.open("GET","hw9.database.php?name="+str,true); xmlhttp.send(); } I'm learning AJAX at the moment. The code here basically receives the echo from the PHP and then puts it in element id games. My question is, if I wanted to have AJAX send 3 different http requests to 3 different PHP scripts and if I wanted to retrieve data from each one and then put it in 3 different element id's then would I make 3 copies of this same function? I would imagine that there should be a more efficient way. Thanks!

  • RedirectStandardInput crashes program

    - by Roman
    Hi, the following code is to open a console application (which uses pdcurses for output, nothing special): myProcess.StartInfo.FileName = "some.exe"; myProcess.StartInfo.UseShellExecute = false; myProcess.StartInfo.CreateNoWindow = false; myProcess.StartInfo.RedirectStandardInput = true; myProcess.Start(); The Problem is that it opens the designated window but directly closes it (it's barely visible). Starting the program without RedirectStandardInput works. The problem is that it does not throw an exception nor any error-message. What is wrong with my code? How can I write input to the program? Thanks.

  • How to determine pixel color of System.Windows.Controls.Image?

    - by csciguy
    I have an Image from (System.Windows.Controls.Image). This image is positioned on a main canvas. I want to determine the alpha channel value of the mouse cursor when I click on any portion of this image. When doing something like the following, I'm getting an exception. {"Value does not fall within the expected range."} System.Exception {System.ArgumentException} Code: try{ CroppedBitmap cb = new CroppedBitmap(ac.displayImage.Source as BitmapSource, new Int32Rect((int)mousePoint.X, (int)mousePoint.Y, 1, 1)); byte[] pixels = new byte[4]; cb.CopyPixels(pixels, 4, 0); } catch (Exception ex) { System.Diagnostics.Debug.WriteLine(ex.Message); } The mousePoint.X, and mousePoint.Y are obtained when the user clicks on the main window. Is there a better way to do this?

  • E.cancel loop in Visual basic

    - by Ahmed
    I am making an server control application ( simple with some buttons to start/stop the server ) And when the user wants to close the application there will be prompted an confirm box. Private Sub Form1_FormClosing(sender As Object, e As FormClosingEventArgs) Handles Me.FormClosing Dim response As Integer response = MsgBox("Are you sure you want to stop the server", vbYesNo, "Stop Server ?") If response = vbYes Then Shell("cscript ""stop.vbs""", 1) Close() Else e.Cancel = True End If End Sub That is the code I have now. But when I start the application and close it with the X button or with "Close Window" I will be prompted with the question until I click on no, then it will close. It's a loop and it stops when you first click on yes then on no. Can someone help me with solving this ?

  • Catch and Show an error from a WCF service call in javascript.

    - by cw
    Hello, I'm calling a WCF service through javascript and right now it's not showing any errors that might occur on the service side to the user. I have the code below and am looking for a better way to inform the user an error has occured, including the call stack and error message if possible. The service itself throws a FaultException if an error has occured. However, I want to catch that error in the javascript call and show it to the user. Here is the js code to call the service function Save() { var saveInfo = $("._saveInfo").val() app.namspace.interfacetoservice.Save( saveInfo, function(results) { if (results == true) { window.close(); } else { alert("error saving"); } } ); } Thanks for the help!

  • Bash PS1 settings - how to get the current folder back as the terminal title

    - by Max Williams
    Hi all. I recently added these lines to my ~/.bashrc file to show the current branch if i'm in a git working folder, and it works nicely for that. However, what i've lost is that the current folder name used to be shown in the tab for the terminal i have open, and now it isn't: it always just says 'Terminal'. Can i get that back and still keep the git stuff? Here's the lines in question - it's the second one that's the issue, as commenting out just the second line fixes the problem. source /etc/bash_completion.d/git PS1='\h:\w$(__git_ps1 "\[\e[32m\][%s]\[\e[0m\]")$ ' I've been looking at explanations of the options for PS1 but can't see anything about the terminal window's title in there. Can anyone advise? thanks, max

  • jQuery/Ajax/javascript in FireFox Error when using $.post/$.get

    - by IsenGrim
    uncaught exception: [Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE)" nsresult: "0x80004005 (NS_ERROR_FAILURE)" location: "JS frame :: http://localhost/scripts/jQuery.js :: anonymous :: line 808" data: no] Line 0 is the error i get when i bring up firebug. This only happens in firefox (and maybe other browsers) but the code works fine in IE8. I have codes like this in jquery: $("#Logout").live("click", function (e) { e.preventDefault(e); $.post("/logout.php", {}, function () { //--a bunch of animations--// window.location = "/login.php"; } }); I have no idea whats wrong as even the error message is not helpful at all.. inside logout.php: <?php session_start(); session_destroy(); ?> Also dont work if I used GET or inserted phantom data. Or is there a more elegant way to do this?

  • Get HTML DOM with CSS

    - by 2x2p1p
    CSS can apply styles in elements through one ID, class or pseudo-selector, but I would like to get the HTML tree, something like in javascript: <script type = "text/javascript"> window.onload = function () { var div = document.getElementsByTagName ("div"); div[0].style.backgroundColor = "gray"; div[0].style.padding = "20px"; } </script> So for example: <style type = "text/css"> div[0] { /* Wrong but i tried :( */ background-color: gray; padding: 20px; } </style> <div > <div>...</div> </div> I'm tired of assign IDs to millions and millions of elements; is there a way to do this?

I managed with opera to see page variables parsed so I can get to the download page but I must make that download in a folder without the download pop-up

  • Visual Studio detaches from application as soon as debugging starts

    - by rwmnau
    I have a web application that I've always been able to run in Visual Studio and it debugs just fine (breakpoints work, I can pause execution, etc). Recently, the behavior changed suddenly, and a few things happen: I start debugging, it lauches IE and loads the application, but after a few seconds (sometimes the page hasn't even displayed yet), Visual Studio acts as if debugging has stopped - I'm able to edit code in VS again, and the "Play" button on the toolbar is enabled. The application continues to run in the IE window just spawned, but I'm not attached to it During this few seconds that VS is "debugging", because it detaches, my breakpoints show as hollow - as if I'm set to "Release" mode and they won't be hit. In fact, I have a breakpoint set in Page_Load, and it skips right by. I've checked, and I'm set to debug mode, though the compile mode dropdown is missing from my toolbar (I checked in the build properties to ensure I was in debug mode). Can anybody shed some light here?

  • Log out of an SSH session into Erlang VM without stopping the VM or leaving stale processes

    - by Garret Smith
    I have an Erlang application running as a daemon, configured as an SSH server. I can connect to it with an SSH client and I get the standard Erlang REPL. If I 'q().' I shut down the Erlang VM, not the connection. If I close the connection ('~.' for OpenSSH, close the window in PuTTY) some processes remain under the sshd_sup/ssh_system_xx_sup tree. These appear to be stale shell processes. I do not see any exported function in the shell module that would let me shut down the shell (and therefore the SSH connection) without affecting the entire VM. How should I be logging out of the SSH session to not leave stale processes in the VM?

  • Inspection of Insert Statement When Using LINQ's SubmitChanges

    - by Code Sherpa
    Hi. I want to see what my insert statement would look like as if I was wiring up an text-based ADO.NET command. How do I do this? I have been following the below link: http://damieng.com/blog/2008/07/30/linq-to-sql-log-to-debug-window-file-memory-or-multiple-writers And have added the DebugTextWriter class to my project. So, now, in my code I have the following which doesn't really do anything and I don't think its right: using(WorkbookDataContext dc = _conn.GetContext()) { if(profile.ProfileId > 0) { dc.Profiles.Attach(profile, true); } else { dc.Profiles.InsertOnSubmit(profile); } dc.Log = new DebugTextWriter(); #if DEBUG dc.Log = new System.IO.StreamWriter("linq-to-sql.log") { AutoFlush = true }; #endif dc.SubmitChanges(); } Any ideas what I am doing wrong and/or how to inspect my LINQ insert statement correctly? Thanks

  • IE8 no honoring display:none

    - by user357034
    I have the following markup on a page and unfortunately I do not have direct access to it. . This page is opened in an iframe. There is other code on the page but it is not relevant so I have not posted it. The only access to target the code in via css. I want to not display the close button so I added this to the css file img[alt='Close'] {display:none !important;} this is the markup <td align="center"><a href='javascript:window.close()'><img src='v/vspfiles/templates/100/images/buttons/btn_close.gif' alt='Close' border=0></a></td> It works as expected in all browsers that i have tested (firefox, Opera, Safari) but in IE8 it seems to ignore this css and shows the button. Not sure if it doesn't like the selector or perhaps I have a syntax error. Not sure where to go from here.

    - by SpikETidE
    Hi everyone... While looking for a way to temporarily save the search results when a user searches for a hotel free between particular dates i came across temporary tables. But certain questions are not answered even in mysql manual.... like... Will the temporary table be unique for each user that executes the script...? Or will it be overwritten when two different users run the script at the same time...? When will the table be destroyed..? When the user closes the browser window or just navigates away from the page in which the script runs...? Thanks for your clarifications...
