• IIS 7 Cannot Access Website

  - by UberError

  We can access our website from other systems, but when logged into the local machine where the site is hosted it does not resolve to the site... for example: http://mysite.com/folder/page.aspx gets a 404.... from the local machine we also cannot ping mysite.com ... What are some common things to check to troubleshoot this issue? I'm new to IIS 7 so sorry for the vague question.

• Trouble installing Mercurial 1.5 on Mac OS X 10.5.8 (without using MacPorts)

  - by gjvis

  I'm having trouble installing Mercurial 1.5 (build 20100307) from the prebuilt installer on Mac OS X 10.5.8. The installer is halting telling me that I need to install Python 2.6 to continue. I've installed the latest version of Python (2.6.5) twice now but it's not helping. which python is reporting /Library/Frameworks/Python.framework/Versions/2.6/bin/python, but I can see that I also have 2.3 and 2.5 in /System/Library/Frameworks/Python.framework/Versions directory, which I suspect is being picked up by the installer ahead of the 2.6 install. If possible I'd like to install Mercurial and Python without having to resort to MacPorts, but if that is the only option then so be it :)

• New install indicator while install updating on Ubuntu

  - by Phuong Nguyen

  In the update manager of ubuntu I see several libraries marked with New Install. I don't know what is the benefit I can get from that New Install? What if I just want a normal upgrade, not a New Install? (I have 3 Linux Kernel versions right now (that I can see and select from Grub menu), and I think I don't need all of them since I always use the latest Kernel).

• Faut-il être bon en math pour être un bon développeur ? Quelle place ont les maths dans votre parcou

  Faut-il être bon en math pour être un bon développeur ? Quelle place ont les maths dans votre métier et votre parcours ? Faut-il être bon en math pour être un bon développeur ? La question mérite d'être posée. Certes, l'informatique est à classer, dans le système universitaire, du coté des sciences "dures", par oppositions aux sciences sociales et humaines. L'enseignement des mathématiques et la rigueur qu'elles amènent paraissent donc indispensable. Pourtant, beaucoup, comme Alan Skorkin - qui vient d'aborder ce sujet sur son blog -, reconnaissent qu'ils n'ont jamais vraiment eu besoin des maths dans leur travail. La position de Alan Skorkin est c...

• How to add locale aware CSS to an individual component in ADF Faces.

  - by [email protected]

  When creating a skin in ADF Faces, it's (relatively) easy to add locale aware CSS using the :rtl psuedo-class on the end of a skinning key.  Example:af|inputListOfValues::content {  padding-left: 3px;}af|inputListOfValues::content:rtl {  padding-left: 0px;  padding-right: 3px;}In this example, we want some padding before the start of the text in the content element of the component.  In right to left locales, the start of the text is on the right side by default, so we need to change the padding from the left to the right.Let's say, however, that you want to specify a locale aware CSS style on an individual component using the contentStyle attribute.  There is a handy ADF Faces EL function to help you out here: isRTL.  For our example, let's say we want an inputText component whose text content is 'end' aligned.  If you weren't considering RTL locales, you could code this as:<af:inputText id="idInputTextRight" label="right aligned" value="Test"                    contentStyle="text-align: right;"/>This, however, will be right aligned regardless of locale. This is where isRTL() comes to the rescue.  This is how we would code this to be locale aware:<af:inputText id="idInputTextEnd" label="end aligned" value="Test"                     contentStyle="text-align: #{af:isRTL()?'left':'right'};"/> The af:isRTL() EL function returns true if we are rendering in RTL, so we can use it to pick the appropriate text alignment.

• iPhone CALayer Stacking Order

  - by Brian

  I'm using CALayers to draw to a UITableViewCell. I'm trying to figure out how layers are ordered with the content of the UITableViewCell. For instance: I add labels to the UITableViewCell in my cellForRow:atIndexPath method In the drawRect method of UITableViewCell I draw some content using the current context Also, in drawRect I add a few sublayers So what would be the order of these elements. I know I have zPosition on the CALayers but I'm not sure if they are always on top of any subviews of the UITableViewCell. And I'm not sure where the content that is drawn in drawRect comes in the order. Any help or links to documentation would be great. I have read through the Core Animation Programming Guide and didn't see anywhere where this would be answered.

• Array performance question

  - by Konrad

  I am very familiar with STL vector (and other container) performance guarantees, however I can't seem to find anything concrete about plain arrays. Are pointer arithmetic and [] methods constant or linear time?

• SharePoint Licensing

  - by Adam

  Hi - we are thinking of using SharePoint to host a web app for which we will allow internal staff and licensed external customers to access a website built on SharePoint. I am thinking that for each authenticated user (logged in) we would need an OS CAL & a SharePoint CAL & we would need a processor license for SQL Server - Is this correct & what about non-authemticatedc website "browsers"? Any advice much appreciated.

• Guaranteed semaphore order?

  - by Steve_

  The documentation for the .NET Semaphore class states that: There is no guaranteed order, such as FIFO or LIFO, in which blocked threads enter the semaphore. In this case, if I want a guaranteed order (either FIFO or LIFO), what are my options? Is this something that just isn't easily possible? Would I have to write my own Semaphore? I assume that would be pretty advanced? Thanks, Steve

• Visual C# GUI Designer basic tutorial

  - by cusack

  Hi, can you recommend a Visual C# Form Designer tutorial that is targeted at experienced programmers who have at least a basic knowledge of C# but are new to the VS C# Form Designer. At least it shouldn't be targeted at programming newbs, like Introduction to Visual C# 2008 Express Edition (it explains how a comment looks like in C#). So far I've found C# Programming Tutorial - Programming Winforms in C# on stackoverflow. Wishlist: ;-) I'm more interested in focus on the designer itself rather than an explanation of single gui-elements. In other words explaining separation between generated-code, what to not edit manually (visual-c#-designer-responsibility) and on the other hand the parts for which the programmer himself is responsible. So a little more abstract best-practice point of view pointing out some caveats would be great as well. I would prefer text over video as well, but that's minor. /Wishlist Perhaps even a Microsoft reference specific to the Visual c# forms designer (which I seem to have been unable to find) would be helpful.

• How can I add methods from a Java class as global functions in Javascript using Rhino?

  - by gooli

  I have a simple Java class that has some methods: public class Utils { public void deal(String price, int amount) { // .... } public void bid(String price, int amount) { // .... } public void offer(String price, int amount) { // .... } } I would like to create an instance of this class and allow the Javascript code to call the methods directly, like so: deal("1.3736", 100000); bid("1.3735", 500000); The only way I could figure out for now was to use ScriptEngine engine = new ScriptEngineManager().getEngineByName("js"); engine.put("utils", new Utils()); and then use utils.deal(...) in the Javascript code. I can also write wrapper functions in Javascript for each method, but there should be a simpler way to do this automatically for all the public methods of a class.

• jQuery UI Autocomplete - style like a standard <SELECT>

  - by jkohlhepp

  I'm on the verge of starting a new web application that is likely to have need for both standard, simple dropdowns as well as more feature-rich autocomplete controls for longer lists of values, better type ahead behavior, etc. I'm planning on using the jQuery UI Autocomplete widget along with some combobox behavior as detailed here: http://jqueryui.com/demos/autocomplete/#combobox My concern is that "out of the box" the Autocomplete widget looks very different than a standard control. Since is not easy to skin/style, I'm hoping to adjust the Autocomplete to look & feel as close to the as possible, except in the cases where the increased functionality justifies a different L&F. What is the best way to go about reskinning the Autocomplete to look more like a ? Has this already been done somewhere? Should I use jQuery UI theming? Other options?

• Delphi overwrite existing file on save dialog

  - by AfterImage

  Hello everyone, I am using the TSaveDialog component to save a file from a button click. However, I am having trouble with saving on an existing file name. Generally, when you want to save over an existing file in Windows, a message box pops up asking you if you really want to overwrite the file. This is not the case with the TSaveDialog component and it will go ahead and write over the file without asking. I was hoping there was a TSaveDialog function or event that I could use but I have not seen anything that looks like it handles this. So it could be that I simplely haven't found the correct method to use. If there is an event, I could use if FileExists(saveDialog.FileName) then //and so forth but the events TSaveDialog has are OnCanClose, OnClose, OnFolderChange, OnIncludeItem, OnSelectionChange, OnShow, OnTypeChange... My question is, how do I pop up a message box to ask the user if they want to overwrite the existing file using the TSaveDialog component. Thanks.
