• What's the best way to recruit talented female developers?

  - by Molly Wally

  I work on a team with a dozen men. They're great. I like them and all, but can't help wonder why it's so hard to find other technical women. I know they exist because I've met them at conferences, read their blogs, and see them on campus. My guess is there's something about our team that keeps them away. How can we recruit talented women without resorting to gimmicks? I'm not looking for complete gender parity, but why is it that some teams have a 50/50 gender split and ours is completely lopsided?

• 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.)

• 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)?

• 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"))?

• DDD / Layers and legacy systems

  - by CSM

  I have to refactor a complex C# app (many dialogs, mixed logic and so on). There is a part managing the communication with special hardware equipments (sending commands and receive data via asynchronous c# callbacks). The code is "spaghetti" with mixed UI/Logic/Communication/etc and my task is to split the layers in a DDD sense. So, to which layer belongs a callback driver routine? The callbacks are creating "bubbles" in the system, up to the UI layer and because of this I cannot enforce the essential principle that any element of a layer depends only on other elements in the same layer or on elements of the layers "beneath" it. Thank you in advance.

• Set focus to another control after TreeView click

  - by Chintan Shah

  I have a TreeView control in a Windows application. I am opening another window from the TreeView click (Single Click) event (in tabbed environment, so all windows will appear as a tab in Visual Studio). I want to set focus to one control of the new window. The problem is that, I am able to set the focus on the double click event of the TreeView. But same doesn't seem to be working with the TreeView single-click event. Any workarounds?

• Binding a combobox in XAML to a childwindow property

  - by AlexB

  Hi, I want to display a child window that contains a combobox with several values coming from one of the child window's property: public partial class MyChildWindow : ChildWindow { private ObservableCollection<MyClass> _collectionToBind = // initialize and add items to collection to make sure it s not empty... public ObservableCollection<MyClass> CollectionToBind { get { return _collectionToBind; } set { _collectionToBind = value; } } } How do I bind in XAML my combobox to the ComboBoxContent collection (both are in the same class)? I've tried several things such as: <ComboBox x:Name="linkCombo" ItemsSource="{Binding Path=CollectionToBind }" DisplayMemberPath="Description"> I've only been able to bind it in the code behind file and would like to learn the XAML way to do it. Thank you!

• Tabbed browsing, programaticaly navigating to another open tab

  - by jdr120

  Hello, I'm in a discussion with my co-worker. We have a web application in a tabbed browsing environment, say with 2 tabs open. Tab2 has a link to tab1, when I click the link, it opens tab1 in a new tab. We want to detect if tab 1 is already open, if so then set focus to tab1 (and not open a new window). He has gotten this working in a broswer window environment, but says it is not possible in a tabbed environment. Is it possible to for javascript to determine if tab1 is already open and then just set focus to that tab? Thanks in advance!

• Scale div in an upwards direction, instead of down?

  - by Derrick

  I have a custom info window over a google map, sometimes these info windows contain an image. When they do, the info window scales down over the marker it is positioned over as soon as the image has finished loading. So the images take longer to load and the div's position has already been calculated by the time the image is finished loading. I do believe there is a way of checking if an image has finished loaded, but that seems a long route - is there not a simple way with JS or CSS to get the div to scale upwards instead of down. Anyone have any clues?

• 2D game big background images for maps

  - by WhiteCat

  Update: this question is general, not specific to Sprite Kit or a single language/platform. I'm toying with Sprite Kit with an idea to make a 2D side-scroller. Now the backgrounds for the maps are going to be hand-drawn and surely bigger than retina display, so the maps could span more than 1 screen in both axis. I imagine loading such a huge image could mean trouble and I don't plan to use tiling. I'm not sure how Sprite Kit splits images bigger than max texture size, if it does. I could split the images myself and use more sprites for each part of the background. What is the usual way to handle this?

• 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!

• How do I get query string value from script path?

  - by TruMan1

  I am adding my Javsacript file in pages with different query strings in the script path like this: Page1: <script type="text/javascript" src="file.js?abc=123"></script> Page2: <script type="text/javascript" src="file.js?abc=456"></script> Page3: <script type="text/javascript" src="file.js?abc=789"></script> In my Javascript file, how can I get the value of the "abc" param? I tried using window.location for this, but that does not work. In case it helps, below is a function I use to find the value of a query string param: function getQuerystring(key, defaultValue) { if (defaultValue == null) defaultValue = ""; key = key.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]"); var regex = new RegExp("[\\?&]" + key + "=([^&#]*)"); var qs = regex.exec(window.location.href); if (qs == null) return defaultValue; else return qs[1]; }

• Referring to a non-final variable data inside an inner class

  - by shoaibmohammed

  Im doing a program in GWT.

• Why can't I find DataTemplates in merged resource dictionaries?

  - by dthrasher

  In my MainWindow.xaml, I have the following reference to a ResourceDictionary: <Window.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="MainSkin.xaml" /> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Window.Resources> In MainSkin.xaml, I define a datatemplate: <DataTemplate x:Key="TagTemplate"> ... </DataTemplate> Deeper within my application, I attempt to use this data template: <ContentControl DataContext="{Binding Tag}" ContentTemplate="{StaticResource TagTemplate}"/> The code compiles successfully, but when I attempt to load a Page or UserControl that contains this StaticResource, I get an exception saying that the TagTemplate can't be found. What am I doing wrong?

• Tool Review: Telerik JustDecompile

  - by Sam Abraham

  In the next few lines, I will be providing a brief review of Telerik’s JustDecompile, a free .Net decompiler and assembly browser. In using Telerik’s 2012 Q3 JustDecompile release, one can see many great features.  First off, I loved the built-in options for loading .Net assemblies automatically using the Open->Load Framework menu option. Other options enable loading assemblies from GAC, XAP URL or locally from disk. The ability to create an “Assembly List” is quiet handy for grouping and saving a “List” of DLLs to load. All loaded assemblies are shown in the left panel of a split-panel screen. Clicking an assembly expands all namespaces within. Drilling further to class level displays the actual source code in the right panel in either IL, C# or Visual Basic. In conclusion, JustDecompile has grown and quickly matured into an indispensible handy tool for us developers. Telerik’s effort in maintaining and updating JustDecompile as well as the company’s commitment to keeping it free is much appreciated and valued.

• Java: Selected rows's index does not changes when I sort them!

  - by adrian7

  Hello, I have a Jtable on which I called the method table1.setAutoCreateRowSorter(true);. So this works on well. But I also have a methos in my JFrame class which is fired when i push a button. It gets the selected rows indexes using this code int selectedRows[] = this.table1.getSelectedRows();. And displays an edit window for the first row corresponding in the selected interval. The problem is that if I don't click on column's headers (I mean i don't sorte them at all) my method works perfect. But when I sort the row, the indexes of the rows doesn't seems to change at all - thus resulting an edit window for the old row whicn was initially in that position before making any sort. I am using JDK 6 could anyonw give ma a tip?

• why does backbone not send the delete?

  - by Nippysaurus

  I have a very basic backbone (sample) application which just creates and destroys model items. When the model is created the object is persisted with a POST to the web server, but when the model is destroyed there is no DELETE sent to the server? Any idea why this might be? very basic model: window.User = Backbone.Model.extend({ urlRoot: 'users' }); my test code just to create and delete the model: var model = null; $(".add").click(function(){ if (model == null) { model = new window.User; model.set({name: 'meeee'}); model.save(); } }); $(".remove").click(function(){ if (model != null) { model.destroy(); } }); The JSON response when creating the model seems good too:

• 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.

• Splitting Logic, Data, Layout and "Hacks"

  - by fjdumont

  Sure, we all heard of programming patterns such as MVVM, MVC and such. But that isn't really what I'm looking into as Layout, Data and Logic is already pretty much split up (XML-Layout markup, Database, insert your language of choice here). The platform I am developing for is hard to maintain over the updated versions and older OSes. The project significantly grew up over the last few months and dealing with different platform versions really is a pain. For example simply disabling an user interface control for all existing versions took me around 40 lines of code in the logic layer, wrangling around with invocation, delegation, singletons that provide UI handling and so on. Is there a clean way to keep track of those "hacks" by maybe excluding it into separate classes or even packages? Should I overwrite existing framework code in order to handle my requirements correctly? If so, does that concept have a name?

• 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

• Making div fixed vertically but glued to the page's border horizontally

  - by George

  Hi! Can you please go to: http://www.binarymark.com/Products/ColorPickerPro/default.aspx and note the page's layout. What I want to do is to stick or "glue" some small div to the right side of the page, that is so that it's just outside of the right frame of the page. However, vertically I want the div to be fixed to a Window, that is no matter how much the page is scrolled, it should remain a fixed 300px from the top edge of the window. Here's what it should look like http://www.binarymark.com/layexp.png Can you help me please? Seems easy, but I have no idea how to combine vertical fixed positioning and horizontal relative/absolute positioning and making sure it supports all major browsers. Thanks.

• Automatically hide toolbar when it is not in use.

  - by Koning WWWWWWWWWWWWWWWWWWWWWWW

  I am creating a Cocoa Application for Mac OS 10.6 , and I want to hide the toolbar of an NSWindow automatically when it is not in use for at least 30 seconds. I think this can be done with NSTimers, but I'm not familiar with them and I don't know how I can implement this. Another problem is that both the NSToolbarDelegate and NSWindowDelegate protocols don't have delegate methods like toolbarDidShow: Can anyone point me in the right direction? Thanks. PS. This is not to punish the user, but rather give the user a cleaner window (the window consist of only a toolbar for color and font and a text-view). PPS. Can the hide-toolbar-animation lead into a problem with the cursor while the user is typing?
