• Yitzhak "OR" in separate calls to Where

  I'm trying to do the equivalent of this in LINQ: StringBuilder q = new StringBuilder("SELECT * FROM customer WHERE city = 'New York'"); if (westCoast) q.Append(" OR city = 'Los Angeles'"); Here's what I have so far: var q = dc.Customer.Where(c => c.City == "New York"); if (westCoast) q.Where(c => c.City == "Los Angeles"); But I end up with "WHERE city = 'New York' AND city = 'Los Angeles'"; How do I tell it to use OR instead, when separate calls to Where are made Thanks!   super_bly wrote: I'm trying to do the equivalent of this in LINQ: StringBuilder q = new StringBuilder("SELECT * FROM customer WHERE city = 'New York'") ...Show All

• Carbond Question on the Media Center Animation

  I have been messing around trying to achieve a certain animation on the Media Center 2005...I have been able to get most of the Animations but only one i haven't figured out,i dont think it can be accomplished just with the Timeline using the transform... When you first roll the mouse over a button the additional options slide out to the right ( I have this animation already), the one i'm trying to nail. Is when you roll the mouse over the Options on the right side,the Buttons on the Left DropBack into the screen ... I know by setting the Position to the Left side of an Object it will Pivot at that Point,now its just getting Right Side of the Object to DropBack into the screen..

• Bertrand Caillet How can a programmer call .chm help files from within VB

    This is a serious problem for Vista. I can call the help exe hh.exe from VB5 in XP to run my .chm help file but apearantly this is not allowed by Vista. I tried calling HelpPane.exe and passing it the .chm but to no avail. The problem seems to be that Vista will not allow a program to call any other program. Any ideas would be appreciated! Thanks, Sam Thanks for the reply. I was using shell(helpfile$, 0) and AppActivate(). This worked fine in XP. I changed to HtmlHelp(hwnd, HelpFile$, HH_Display_Topic, 0) and everything now works fine in Vista. Very Happy! Thanks Again!

• Duncan Woods Solution and Solution Configuration missing

  Something's happened to Visual Studio which is causing the Solution Configuration dropdown to disappear from new Web Application projects. It's also causing the "root" (ie the Solution) to disappear from the Solution Explorer, too. New Web Sites are fine, and older Web Application projects still have the Solution Config in them, but any new Web Applications don't work. I've tried repairing Visual Studio with no joy. I can't say for sure what has caused this- it's taken me a while to even notice, to be honest! One thing that might be the cause: I installed the Atlas library into VS about three weeks ago... Might that have changed some settings or corrupted something somewhere That sort ...Show All
