• Javascript functions return lines of function code or "{[native code]}," what am I doing wrong?

  - by DavidR

  I am writing some code to find the user selection in a contenteditable div, I'm taking my code from this quirksmode article. function findSelection(){ var userSelection; if (window.getSelection) {userSelection = window.getSelection;} else if (document.selection){userSelection = document.selection.createRange();} // For microsoft if (userSelection.text){return userSelection.text} //for Microsoft else {return userSelection} } I'm testing it in Chrome and Firefox, if I do an alert(userSelection) within the function or an alert(findSelection();) outside the function, it returns function getSelection() {[native code]}. If I do console.log(findSelection();) it gives me getSelection(). Is there something I've done wrong?

• Set environment variable in Ubuntu

  - by Junho Park

  In Ubuntu, I'd like to switch my JAVA_HOME environment variable back and forth between Java 5 and 6. I open a terminal and type in the following to set the JAVA_HOME environment variable: export JAVA_HOME=/usr/lib/jvm/java-1.5.0-sun And in that same terminal window, I type the following to check that the environment variable has been updated: echo $JAVA_HOME And I see /usr/lib/jvm/java-1.5.0-sun which is what I'm expecting to see. In addition, I modify ~/.profile and set the JAVA_HOME environment variable to /usr/lib/jvm/java-1.5.0-sun. And now for the problem--when I open a new terminal window and I check my JAVA_HOME environment variable by typing in echo $JAVA_HOME I see that my JAVA_HOME environment variable has been reverted back to Java 6. When I reboot my machine (or log out and back in, I suppose) the JAVA_HOME environment variable is set to Java 5 (presumably because of the modification I made in my ~/.profile). Is there a way around this so that I can change my JAVA_HOME environment without having to log out and back in (AND make that environment variable change stick in all new terminal windows)?

• Get Excel.Application object from Process or hwnd in .NET

  - by Abiel

  In C# I am trying to get an instance of an Excel.Application object from a Process object. This seems like it should be really simple yet I cannot figure it out and cannot find an example. To repeat, I have a System.Diagnostics.Process object that I know refers to a running Excel instance. I now need to recover a Microsoft.Office.Interop.Excel.Application object that refers to the process so that I can go about manipulating the Excel application from C#. In case it makes it any simpler, I also have the HWND id and window text associated with the active Excel window. Thanks.

• Sprite not moving when using a function from another class SFML c++

  - by user2892932

  I have a Game.cpp, and I am calling a update function in my Player class. In my player update Function I have it to check for keyboard input, and it seems to work, but whenever I try to call the .move() function, it seems to not work. I get no errors either. I am new to sfml, and decent with c++. Help is appreciated! #include "Player.h" Player::Player(void): vel(0), maxvel(100) { Load("Assets/sss.png",true); } void Player::Update(sf::Sprite& p) { if (sf::Keyboard::isKeyPressed(sf::Keyboard::A)) { moveObject(-3,0, p); } if(sf::Keyboard::isKeyPressed(sf::Keyboard::D)) { moveObject(-3,0, p); } } Player::~Player(void) { } This is the GameObject cpp #include "GameObject.h" #include <iostream> GameObject::GameObject(void) { isLoaded = false; } void GameObject::Load(std::string flname, bool isPlayer) { if(!tex.loadFromFile(flname)) { EXIT_FAILURE; } else { if(isPlayer) { if(!tex.loadFromFile(flname, sf::IntRect(0,0,33,33))) { EXIT_FAILURE; } else { std::cout << "Loading image" << "\n"; filename = flname; spr.setTexture(tex); isLoaded = true; } } else { std::cout << "Loading image" << "\n"; filename = flname; spr.setTexture(tex); isLoaded = true; } } } void GameObject::Draw(sf::RenderWindow & window) { if(isLoaded) { window.draw(spr); window.display(); std::cout << "Sprite drew" << "\n"; } } void GameObject::setPos(float x, float y) { if(isLoaded) { spr.setPosition(x,y); } } sf::Vector2f GameObject::GetObjPos() { return spr.getPosition(); } sf::Sprite& GameObject::getSprite() { return spr; } void GameObject::moveObject(float x, float y, sf::Sprite& sp) { sp.move(x, y); } GameObject::~GameObject(void) { }

• How do I start a XUL Runner application maximized?

  - by Anthony D

  I've started developing my first app with XUL and I've run into a problem that I can't seem to solve. All I want to do is have my app start maximized. I've set the sizemode attribute to maximized on my top level window element but that has no effect. My prefs.js file has the following line: pref("toolkit.defaultChromeFeatures", "chrome,centerscreen,menubar,resizable,status,toolbar,scrollbars"); This also does not work. My window appears and it only has a close button (X) and does not have a minimize or maximize button. Any ideas???

• WPF attach popup with a control

  - by viky

  I have a scenario where I am displaying a popup on my control. I am able to do this using PlacementTarget, Position, etc. My problem is when I resize the window and move it to somewhere else in the desktop, the popup remains stationary meaning it doesn't move with the control set as PlacementTarget. I was able to hide it in case of other window getting focus. But not able to attach it with my control. How can I solve this problem? Is there any other such control available?

• using multi-markers with multi info-windows

  - by mohsen

  I have an array of info-windows corresponding to an array of markers. Now, I have a problem, I use the below code to generate an info-window, when clicking on the marker all the markers disappear unless one, also when I click on that marker there is no info-window come out. What is the wrong with my code ? or what shall I do ? Any answer will be very appreciated, Thanks in advance. This code is inside a for loop: infoWindoArray[i][j] = new google.maps.InfoWindow({ content:"Lat: "+this.position.lat() + "\nLng: " + this.position.lng() + "\n"+ this.customInfo, }); google.maps.event.addListener(AllMarkers[i][j], 'click', (function(x) { return function() {infoWindoArray[i][j].open(map,AllMarkers[i][j]);} })(x));

• @@TRANCOUNT and a current connection

  - by AspOnMyNet

  Assume I connect to SQL server 2008 via SQL Server Management Studio ( SSMS ) and open new window W1 by clicking on New Query tab and write the following inside W1: BEGIN TRANSACTION; If I execute this statement 5 times, and then write (inside W1) SELECT @@TRANCOUNT; , then the value returned will be 5. But if I open another window W2 ( inside the same SSMS instance and thus on the same connection ) and write inside W2 SELECT @@TRANCOUNT; then value returned will be 0. @@TRANCOUNT variable returns the number of active transactions for the current connection. Both W1 and W2 windows were opened on the same connection, so shouldn’t ( according to the above quote ) in both W1 and W2 variable @@TRANCOUNT hold the same value? thanx

• In forms application, is there any Alternative to MsgBox?

  - by GuruC

  I like how MsgBox stops all further processing until it's clicked but I don't like how it pops that little msgbox in the middle of the screen, which I then have bring to the front if there is a window covering it. Is there a way to do something like a msgbox but keep it on my Form (which is always in view) so I can go ahead and click a button on the form instead of having to bring the little msgbox window on top of windows that may be covering it. I use the msgbox to inform me that a certain situation has happened, which I manually fix and when I'm done I click the MsgBox to continue processing. It'd be nice to have this button right on the form.

• How to implement a Google-chrome-like title bar for Java SWT application

  - by MartyC

  I have inherited development of a Java/SWT application running on Windows only. One of the feature requests that I need to scope is a Google-chrome-type title bar in place of the SWT windows title bar. The application's tabs appear at the same level as the window control buttons. My understanding is that I will need to: write a Windows widget capable of rendering the custom look and managing tabs as opposed to menus. expose the Windows widget as a dll for use in Java via JNI write a custom SWT widget to wrap it and expose the tab management interface. I have a lot of experience with Java programming, GUI programming with Swing/AWT, and non-GUI C# programming. Windows GUI programming and SWT are new to me so I'm not sure where to start. The best I have found so far is a 2001 article on writing your own SWT widget. My biggest unknown is the best way to implement a custom Windows application-window.

• How to design websites for all display sizes

  - by katie bekell

  I like to use a lot of unique graphics on my pages, which often results in making different page sizes depending on available screen width/height. Here are two examples: http://www.uvm.edu/~areid/homesite/ - the image floats at the bottom of my screen but on a larger browser, the image floats near the middle making it look off. It looks best when the bottom of the window aligns with the bottom of the image www.stevenlebel.com - it loads two different pages depending on what monitor size is detected. This seems like a lot of redundant coding. My question is, how can I make sliced/Photoshop images transition well to different screen sizes. Does Photoshop allow you to make DIVS instead of tables? Can i make each of the slices created by Photoshop grow/shrink when the browser window size changes? If anyone has any input on creating websites like this I would be very interested to hear what they have to say. Thanks Katie

• Exposing classes inside modules within a Python package directly in the package's namespace

  - by Richard Waite

  I have a wxPython application with the various GUI classes in their own modules in a package called gui. With this setup, importing the main window would be done as follows: from gui.mainwindow import MainWindow This looked messy to me so I changed the __init__.py file for the gui package to import the class directly into the package namespace: from mainwindow import MainWindow This allows me to import the main window like this: from gui import MainWindow This looks better to me aesthetically and I think it also more closely represents what I'm doing (importing the MainWindow class from the gui "namespace"). The reason I made the gui package was to keep all the GUI stuff together. I could have just as easily made a single gui module and stuffed all the GUI classes in it, but I think that would have been unmanageable. The package now appears to work like a module, but allows me to separate the classes into their own modules (along with helper functions, etc.). This whole thing strikes me as somewhat petty, I just thought I'd throw it out there to see what others think about the idea.

• How to created filtered reports in WPF?

  - by Michael Goyote

  Creating reports in WPF. I have two related tables. Table A-Customer: CustomerID(PK) Names Phone Number Customer Num Table B-Items: Products Price CustomerID I want to be able to generate a report like this: CustomerA Items Price Item A 10 Item B 10 Item C 10 --------------- Total 30 So this is what I have done: <Window x:Class="ReportViewerWPF.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:rv="clr-namespace:Microsoft.Reporting.WinForms; assembly=Microsoft.ReportViewer.WinForms" Title="Customer Report" Height="300" Width="400"> <Grid> <WindowsFormsHost Name="windowsFormsHost1"> <rv:ReportViewer x:Name="reportViewer1"/> </WindowsFormsHost> </Grid> Then I created a dataset and loaded the two tables, followed by a report wizard (dragged all the available fields and dropped them to the Values pane). The code behind the WPF window is this: public partial class CustomerReport : Window { public CustomerReport() { InitializeComponent(); _reportViewer.Load += ReportViewer_Load; } private bool _isReportViewerLoaded; private void ReportViewer_Load(object sender, EventArgs e) { if (!_isReportViewerLoaded) { Microsoft.Reporting.WinForms.ReportDataSource reportDataSource1 = new Microsoft.Reporting.WinForms.ReportDataSource(); HM2DataSet dataset = new HM2DataSet(); dataset.BeginInit(); reportDataSource1.Name = "DataSet";//This is the dataset name reportDataSource1.Value = dataset.CustomerTable; this.reportViewer1.LocalReport.DataSources.Add(reportDataSource1); this.reportViewer1.LocalReport.ReportPath = "../../Report3.rdlc"; dataset.EndInit(); HM2DataSetTableAdapters.CustomerTableAdapter funcTableAdapter = new HM2DataSetTableAdapters.CustomerTableAdapter(); funcTableAdapter.ClearBeforeFill = true; funcTableAdapter.Fill(dataset.CustomerTable); _reportViewer.RefreshReport(); _isReportViewerLoaded = true; } } As you might have guessed this loaded this list of customer with items and price: Customer Items Price Customer A Items A 10 Customer A Items B 10 Customer B Items D 10 Customer B Items C 10 How can I fine-tune this report to look like the one above, where the user can filter the customer he wants displayed on the report? Thanks in advance for the help. I would have preferred to use LINQ whenever filtering data

• WPF - Two way binding use a user control...binding to object, not an element!

  - by Scott

  I created an object with a simple property with a default value. I then created a user control that has a text box in it. I set the datacontext of the user control to the object. The text box correctly shows the properties default value but I can't seem to update the property value when the user changes the text box value. I created a simple project to illustrate my code. Thanks for the help!! public partial class UserControl1 : UserControl { public UserControl1() { InitializeComponent(); } private string _titleValue; public string TitleValue { get { return _titleValue; } set { _titleValue = value; textBox1.Text = _titleValue; } } public static readonly DependencyProperty TitleValueProperty = DependencyProperty.Register( "TitleValue", typeof(string), typeof(UserControl1), new FrameworkPropertyMetadata(new PropertyChangedCallback(titleUpdated)) ); //Don't think I should need to do this!!! private static void titleUpdated(DependencyObject d, DependencyPropertyChangedEventArgs e) { ((UserControl1)d).TitleValue = (string)e.NewValue; } } <UserControl x:Class="WpfApplication1.UserControl1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" mc:Ignorable="d" d:DesignHeight="300" d:DesignWidth="300"> <Grid> <TextBox Height="23" HorizontalAlignment="Left" Margin="94,97,0,0" Name="textBox1" VerticalAlignment="Top" Width="120" Text="{Binding Path=TitleValue, Mode=TwoWay}"/> </Grid> </UserControl> public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); var dummy = new DummyObject("This is my title."); userControl11.DataContext = dummy; } private void button1_Click(object sender, RoutedEventArgs e) { MessageBox.Show("The value is: " + ((DummyObject)userControl11.DataContext).Title); } } <Window x:Class="WpfApplication1.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" xmlns:my="clr-namespace:WpfApplication1"> <Grid> <my:UserControl1 HorizontalAlignment="Left" Margin="95,44,0,0" x:Name="userControl11" VerticalAlignment="Top" Height="191" Width="293" TitleValue="{Binding Path=Title, Mode=TwoWay}"/> <Button Content="Check Value" Height="23" HorizontalAlignment="Left" Margin="20,12,0,0" Name="button1" VerticalAlignment="Top" Width="75" Click="button1_Click" /> </Grid> </Window>

• Opening response stream in silverlight

  - by John Maloney

  Hello, I am attempting to return a image from a server using Silverlight 3. The server returns the Response stream like this: context.Response.ContentType = imageFactory.ContentType imgStream.WriteTo(context.Response.OutputStream) imgStream.Close() context.Response.End() On the Silverlight client I am handling the stream like: Dim request As HttpWebRequest = result.AsyncState Dim response As HttpWebResponse = request.EndGetResponse(result) Dim responseStream As IO.Stream = response.GetResponseStream() I want to take that stream and open the browsers save dialog, one option I have explored is using the Html.Window.Navigate(New Uri("image url")) and this opened the correct browser default dialog but it is not an option because I need to send extended information(e.g. XML) to the server through the HttpRequest.Headers.Item and the Navigate doesn't allow this. How can I take a Response Stream and force the default browser Save dialog to appear from the Silverlight Application without using the Html.Window.Navigate(New Uri("image url"))?

• How to pop Toolwindow in a defined position

  - by Enmanuel

  Hi everyone. Im trying to integrate a toolwindow in a Winforms application, it will be a tiny floating window to display element details in a listbox. What I need is pop the window in a relative position to the control that triggers the action, so here is the thing: the Location property gives me the relative position of the control from its container (the main form in this case) so this is the workaround im using: public void Show(kTextBox source) { Point absCoord = source.PointToScreen(source.Location); this.Location = this.PointToClient(absCoord); base.Show(); } Basically this is: get the absolute control position and set this position (previously converted into owner relative) to the toolwindow. I think it should work just fine but is missing for a certain degree, and it varies depending what control i use. Its kinda confusing. Been there anyone?? Thanks in advance.

• Why does Printing from Javascript in Air happen out of order?

  - by Bob Bob

  I am trying to print from an Adobe Air App that embeds an AJAX app. The print function looks like this: function printPage() { asyncSetupForPrint(printCallback); } function asyncSetupForPrint(printCallback) { synchronousMethods(); if (printCallback) printCallback(); } function printCallback() { var pjob = new window.runtime.flash.printing.PrintJob; var psprite = window.htmlLoader; pjob.start(); // etc... } However the print dialog is coming up before the synchronous methods have been executed. Is the AIR JS runtime optimizing something? And if so, is there any way to stop it doing that? (The setup function is doing things like changing the resolution to huge*huge so that the print out looks ok.)

• Pipe between two console applications?

  - by ronag

  How can I pipe between two separate console application running in different console windows? e.g. I would like to do something similar to: ffmpeg -i 0.flv -vcodec mpeg4 -f asf -s cif - | vlc - However, I would like to do this from two separate windows, which doesn't work, I guess this is because standard out is local to cmd windows. cmd window 1: ffmpeg -i 0.flv -vcodec mpeg4 -f asf -s cif - cmd window 2: vlc - Is there any way to programmatically achieve this? What exactly does | do behind the scenes?

• Saving data in custom class via AppDelegate

  - by redspike

  I can't seem to save data to a custom instance object in my AppDelegate. My custom class is very simple and is as follows: Person.h ... @interface Person : NSObject { int _age; } - (void) setAge: (int) age; - (int) age; @end Person.m #import "Person.h" @implementation Person - (void) setAge:(int) age { _age = age; } - (int) age { return _age; } @end I then create an instance of Person in the AppDelegate class: AppDelegate.h @class Person; @interface AccuTaxAppDelegate : NSObject <UIApplicationDelegate> { ... Person *person; } ... @property (nonatomic, retain) Person *person; @end AppDelegate.m ... #import "Person.h" @implementation AccuTaxAppDelegate ... @synthesize person; - (void)applicationDidFinishLaunching:(UIApplication *)application { // Override point for customization after app launch [window addSubview:[navigationController view]]; [window makeKeyAndVisible]; } - (void)applicationWillTerminate:(UIApplication *)application { // Save data if appropriate } #pragma mark - #pragma mark Memory management - (void)dealloc { [navigationController release]; [window release]; [person release]; [super dealloc]; } @end Finally, in my ViewController code I grab a handle on AppDelegate and then grab the person instance, but when I try to save the age it doesn't seem to work: MyViewController ... - (void)textFieldDidEndEditing:(UITextField *)textField { NSString *textAge = [textField text]; int age = [textAge intValue]; NSLog(@"Age from text field::%i", age); AppDelegate *appDelegate = (AppDelegate *)[UIApplication sharedApplication].delegate; Person *myPerson = (Person *)[appDelegate person]; NSLog(@"Age before setting: %i", [myPerson age]); [myPerson setAge:age]; NSLog(@"Age after setting: %i", [myPerson age]); [textAge release]; } ... The output of the above NSLogs are: [Session started at 2010-05-04 18:29:22 +0100.] 2010-05-04 18:29:28.260 AccuTax[16235:207] Age in text field:25 2010-05-04 18:29:28.262 AccuTax[16235:207] Age before setting: 0 2010-05-04 18:29:28.263 AccuTax[16235:207] Age after setting: 0 Any ideas why 'age' isn't being stored? I'm relatively new to Obj-C so please forgive me if I'm missing something very simple!

• Need help creating flash animation with clickable buttons at the end.

  - by goldenfeelings

  Very inexperienced with Flash, but I hope this is simple enough for someone to walk me through. I'm ultimately trying to create a flash page for an html website that has a brief five-second animation during which 3 buttons fade in (buttons then become clickable after the animation is over). The animation part is done. Right now, I am trying to get my movie to stop and hold on the last frame, where I want to add the 3 buttons that the user can click on to take them to one 3 different html pages of my website. All instructions that I've found online have said to create a new layer for actions, insert a keyframe on the last frame of the movie, and add stop(); in the actionscript window. However, when I have the keyframe selected, my actionscript window says "current selection cannot have actions applied to it". Any ideas? I definitely don't have any objects selected, just the keyframe. Or, am I approaching this totally wrong?

• Disable page redirects using Greasemonkey

  - by Tomer Cohen

  A website I wish to tweak is using window.location in order to redirect specific users to a blocking page. That website is doing it in plain <script> tag, so it is impossible to bypass it by overriding the onload event using document.body.setAttribute('onload','');. Is there another way to inject my code to the page without using Firefox extensions such as NoScript? <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title></title> <script type="text/javascript"> if (1) window.location="http://example.net" </script> </head> <body></body> </html>

• Greasemonkey is getting an empty document.body on select Google pages.

  - by Brock Adams

  Hi, I have a Greasemonkey script that processes Google search results. But it's failing in a few instances, when xpath searches (and document body) appear to be empty. Running the code in Firebug's console works every time. It only fails in a Greasemonkey script. Greasemonkey sees an empty document.body. I've boiled the problem down to a test, greasemonkey script, below. I'm using Firefox 3.5.9 and Greasemonkey 0.8.20100408.6 (but earlier versions had the same problem). Problem: Greasemonkey sees an empty document.body. Recipe to Duplicate: Install the Greasemonkey script. Open a new tab or window. Navigate to Google.com (http://www.google.com/). Search on a simple term like "cats". Check Firefox's Error console (Ctrl-shift-J) or Firebug's console. The script will report that document body is empty. Hit refresh. The script will show a good result (document body found). Note that the failure only reliably appears on Google results obtained this way, and on a new tab/window. Turn javascript off globally (javascript.enabled set to false in about:config). Repeat steps 2 thru 5. Only now the Greasemonkey script will work. It seems that Google javascript is killing the DOM tree for greasemonkey, somehow. I've tried a time-delayed retest and even a programmatic refresh; the script still fails to see the document body. Test Script: // // ==UserScript== // @name TROUBLESHOOTING 2 snippets // @namespace http://www.google.com/ // @description For code that has funky misfires and defies standard debugging. // @include http://*/* // ==/UserScript== // function LocalMain (sTitle) { var sUserMessage = ''; //var sRawHtml = unsafeWindow.document.body.innerHTML; //-- unsafeWindow makes no difference. var sRawHtml = document.body.innerHTML; if (sRawHtml) { sRawHtml = sRawHtml.replace (/^\s\s*/, ''). substr (0, 60); sUserMessage = sTitle + ', Doc body = ' + sRawHtml + ' ...'; } else { sUserMessage = sTitle + ', Document body seems empty!'; } if (typeof (console) != "undefined") { console.log (sUserMessage); } else { if (typeof (GM_log) != "undefined") GM_log (sUserMessage); else if (!sRawHtml) alert (sUserMessage); } } LocalMain ('Preload'); window.addEventListener ("load", function() {LocalMain ('After load');}, false);
