• Visual Studio 2008 (Pre-release) How to keep a Popup aligned with a Control

  My scenario is the following: I want to show a Popup below a TextBox for giving help informations. The problem is that the (opened) Popup stays at the same location when i move the parent Window or the TextBox (through animation). My question: Is it possible to keep the Popup aligned with the TextBox so that it stays below the TextBox even if i move the window Through databinding or something like that (A tooltip is not an option for me.) Well as I have read other posts and help files, I have come to the conclusion there is no other way to do it but manually. You will have to use the Popup's .HorizontalOffset and .VerticalOffset properties in conjunction with the container/window  that is being "moved/dragged". &nbs ...Show All

• .NET Development Server Application Unavailable - 1.1.4322 - access - machine.config

  I have a new workstation (xp pro sp2) that I am having trouble with. When I try to open an ASPX page on the localhost I get the following error: Server Application Unavailable . It refers me to the application event log for more info.

• Visual C# How to catch Exception that throw by timer

  I have a WinForm application and a timer inside. The timer will throw an Exception while event Elapsed. How can I catch this Exception in WinForm One thing that may be of help is to use the WinForms timer rather than the Timers timer or Threading timer. As memory serves, System.Windows.Forms.Timer raises its Tick event on the UI thread of the Form. There are two other Timer classes in the .NET Framework with different behaviors, one of which does in fact execute on the threadpool thread and unhandled exceptions on threadpool threads are as mentioned deadly. Anyway, the significance of using the Forms Timer is that when it throws an exception that goes unhandled it should bubble up to the System.Windows.Forms.Application.T ...Show All

• Visual C# How do I get my random numbers random?

  I have a line that goes like: total += Max3of(Roll(), Roll(), Roll(), Roll(), Roll(), Roll(), Roll(), Roll()); It is trying to find the top 3 rolls out of eight and when I set a break point at the Max3of(...) function and examine the parameters that were passed in they are always all the same(3,3,3,3,3,3,3,3 for example). But if I debug by stepping into the line above and following its calls to Roll() it produces the result I am going for which is random numbers for each roll (3,5,7,9,3,6,2,8 for example). Could you explain why there is a difference when I step through the program and when I just let it run and which is the correct functionality for the line I've written above If it matters this is the code for Roll(): private ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Any regional restriction about Creators Club membership and XNA Game Launcher

  I am an indie developer in Hong Kong. It is so exciting that XNA will be released in 11th Dec, and I decide to join the Creators Club immediately so that I can test my homebrew game on XB360 asap. But I would like to confirm that is it any problem to subscribe and execute the XNA Game Launcher on HK / JP or US XB360 Your creators club membership is tied to your 360 so, there would need to be an active creators club membership for each xbox 360 you wish to run your homebrew on.
