• Visual Studio 2008 (Pre-release) LINQ Preview removes Refactor from VS context menu?

  For some reason the Refactor item disappeared from the context menu that appears when you right-click in the Visual Studio editor. I'm guessing that this was a result of me installing the new LINQ Preview today. Uninstalling the LINQ Preview did not restore the menu item. I had to do a "repair" of Visual Studio to get it back (always a time consuming and fun process). The language service (IDE editor and intellisense) for C# in this CTP is experiencing some problems in this regard. It's not meant to be missing. :-) ...Show All

• Software Development for Windows Vista (State Machine || Sequential Workflow) || (State Machine + Sequential WorkFlow) ??

  There has been a lot of talk about State Machines are good for human workflow and the sequential workflows are good for system workflow.  I would like to present some issues about the state machine for human workflow and get opinions. First, I agree that human workflows are good for the state machine.  First they are easy to understand because there are single state.  So “Awaiting Approval”, and ”Completed PO” are easy to understand.  However using this approach the workflow can only be in one state at anytime. In human workflow a big advantage is to allow a task of items to be handled by more than one resource.&n ...Show All

• Software Development for Windows Vista Playing WMV10 through DirectShow?

  It appears the default codecs only support up through WMV9 and when playing a WMV10 hd file, they don't fully decode with a DirectShow application. Are there DirectShow filters for WMV10 or is the only option to embed Media Player 10 through its SDK Sorry, I haven't worked much with WMV10. I assume you've tried all the basics: Install the latest WMP, the latest WMF and the latest DS ...Show All

• Windows Forms Linking the Menu/Toolbar/Tabs and the Statusbar

  Maybe I'm just missing the right property, or maybe it doesn't exist, but what I'd like to do is link the Menu and Toolbars to the Status bar so that the status bar will reflect the text value of the menu item or toolstrip button that the mouse is hovering over. In other words, if I move my mouse over the open folder icon in my toolbar, the status bar should read "Open". I'm sure I could link this up the hard way with lots of code, but I was hoping some enterprising soul predicted this need and built in the functionality in the first place. Hi, as far as I know you'll have to do it by code but it's not that much code. J ...Show All

  Hi, I have a string and I want to find if that string has ETX charater (End of Text) in it. ETX is a special character with a DEc value of 3, HEX value of 3 and Oct value of 003.
