I am confused how some games (like Crysis) can support both DirectX 9 (in XP) and 10 (in Vista)?
What I understand so far is that if you write a DX10 app, then it can only runs in Vista.
Maybe they have 2 code bases -- one written in DX9 and another in DX10? But isn't that an overkill?

With every server version update, all clients have to be updated, too. Currently, I provide an MSI package which is automatically deployed via Active Directory, however my customers (mostly with 20-300 users each) seem to hate the MSI solution because it is
- Complicated to get it running (little Active Directory knowledge);
- The update process can't be triggered by the server, when a new version is detected;
- Customers can't install multiple versions of the client (e.g. 2.3 and 2.4) at the same time to speak to different servers;
- The update process itself doesn't always work as expected (sometimes very strange behaviour healing itself after a few hours)
I've now made a few experiments with ClickOnce, but that way to unflexible for me and too hard to integrate in my automated build process. Also, it produces cryptic error messages which would surely confuse my customers.
I would have no problems to write the update logic myself, but there the problem is that the users running to self-updating applications have too restricted rights to perform an update. I've found that they are able to write to their Local Application Data directory, but I don't think this would be the typical place to install application files into.

For reasons that don't bear explaining, I am sending ClientMessage from a comand-line utility to a GUI app.Most of the messages end up having the same contents, as the message's purpose is to trigger a synchronous communication process over some side pipes. I've noticed that some of the time I would send two messages, but only one gets delivered. I've traced this to the fact that both messages had the same contents and were sent in the same second (IOW, the log timestamp on the sending was the same number). As soon as I added some dummy contents to the messages to make them all different, the problem went away.
This happened over two different X servers: vncserver and Exceed. Am I hitting some XWindows feature that I am not aware of - some kind of message throttling/compression?

This is the final question in the series.
- The first part: [How do you document
your methods?][2]
- The second part: [Are tests valid
documentation?][3]
This question has to do with what documentation overview do you provide of your system.
You've doc-commented your API, you've written the unit tests, now what kind of documentation do you provide to pull it all together? Is there only documentation from the point of view of the user or do you make an extra effort to provide maintanance programmers with an overview of the system's logic and control flow? Do you discuss why your program is structured the way it is and how far down that rabbit hole do you go?
Should this overview documentation be provided in a single document or broken down by the system's major components? Keeping in mind that the target audience are other programmers what is appropriate for length and tone? Do you mandate what concepts the programmer should be familiar with or is that being to bossy?
Do you write this documentation in a big bang at the end or as you go? If you do it as you go then how do you handle keeping it in sync with design changes?

This means if you just start typing, you completely replace the former contents.
Example: You have spin control that is initialized with the value zero. You tab to it and type "1" The value in the control is now 1.
With Swing, this doesn't happen. The text in the control is not selected and the carat appears at one end or another of the existing text. Continuing the above example:
With a Swing JSpinner, when you tab to the spin control, the carat is at the left. You type "1" and the value in the control is now 10.

For the most part this has worked great, and I really like the possibilities. One difficulty we have come across though is designing against DataBindings. In many cases, the GUI does not populate rows, or other data structures unless the application is run, and a database call is made. Consequently the designer does not have access to the visual layout of the GUI.
What I would like to do, is somehow create some simple stubbed or mocked data that the designer can use to work on the design. The big goal is to have that stubbed data show up in Expression Blend, but then be applied to the real collection at runtime.

1. I define an interface ICommand
2. I create an abstract base class CommandBase which implements ICommand, to contain common code.
3. I create several implementation classes, each extending the base class (and by extension the interface).
Now - suppose that the interface specifies that all commands implement the Name property and the Execute method...
For Name each of my instance classes must return a string that is the name of that command. That string ("HELP", "PRINT" etc) is static to the class concerned. What I would love to be able to do is define:
public abstract static const string Name;
However (sadly) you cannot define static members in an interface.
I have struggled with this issue for years now (pretty much any place I have a family of similar classes) and so will post my own 3 possible solutions below for your votes. However since none of them is ideal I am hoping someone will post a more elegant solution.

I'm thoroughly confused about current state of the art for using OpenID together with `restful_authentication`. The obvious google search gives several well-known pages which do not make sense taken together (considering their timestamps).
What shall I do given that I'm running Rails 2.0 (or 2.1) and I want OpenID authentication alongside usual login/password?
Thank you, | 0 |

It has to be virtualizing, as it must be able to handle several million records.
It should also be multi-select, most treeview controls are not.
Winforms preferred, but will ElementHost WPF if necessary.

The headache comes when I try to put the form inside a <t:panelTabbedPane serverSideTabSwitch="false"> (and thus of course, inside a <t:panelTab> )

Then, [googling for a clue][1], I knew that <t:panelTabbedPane> generates a form called "autoform", so I was getting nested forms. Ok, I fix that creating the <h:form> out of the <t:panelTabbedPane> and eureka! file input worked again! (the autoform doesn't generate)
But, oh surprise! oh terrible Murphy law! All my <h:message> begins to fail. The Eclipse console's output show me that all <h:message> are looking for nonexistents elements ID's (who have their ID's in part equals to they are looking for, but at the end of the ID's their names change)
At this point, I putted a <h:mesagges> tag to show me all errors at once at the beginning of the Panel, and it works fine. So, errors exists and errors show properly at the beginning of the Panel.

Thanks in advance.

tasksForm.Visible = false;
tasksForm.Show();
Long version: I have a WinForms application with two forms: main and tasks. The main form is always displayed. The user can either click a button to open the tasks form, or click some buttons that just run a task directly without opening the tasks form.
When a user asks to run a task directly, I'd like to just call some public methods on the tasks form without showing it. Unfortunately, the task logic depends on stuff that happens in the Form_Load() event. The only way I can find to trigger Form_Load() is to call Show(). The best I've been able to do is to show the form in the minimized state:
tasksForm.WindowState = FormWindowState.Minimized;
tasksForm.Show();
I suppose the cleanest solution would be to pull the tasks logic out of the tasks form and into a controller class. Then I can use that class from the main form and from the tasks form, and only load the tasks form when I need it visible for the user. However, if it's an easy thing to load the form without displaying it, that would be a smaller change.
