• A good way in .NET Winforms to have user entered time frame?

  - by Ben

  Hi, Does anyone know of a good way to have a user enter an amount of time (hours and minutes) using winforms controls? At the moment I have two numeric up downs, one for time and one for minutes that I then parse to create a timespan. The only other idea I have is a text box that a user can enter a "00:00" time in, and validate the input. Both of these ways seem a bit bad (in UI terms) though. Any ideas? Thanks

  - by Preet Sangha

• Visual Studio Missing Warnings

  - by coffeeaddict

  Anyone find where when you open a certain solution (that contains multiple projects) and compile that you're not seen some warnings that your collegues see when compiling the exact same solution at the exact same state? The code is the same. I depend highly on the warnings as a shortcut to find unused methods, etc. But I get nothing during compile.. only a couple based on references to user controls, etc.

• Window Media Player issues two requests for the audio on web page

  - by Ron Harlev

  I'm using Windows Media Player in a web page. I have version 11 installed so that is the version I'm testing with right now. The player is embedded on the page with this HTML: <OBJECT id='MS_mediaPlayer' width="400" height="45" classid='CLSID:6BF52A52-394A-11D3-B153-00C04F79FAA6' codebase='http://activex.microsoft.com/activex/controls/mplayer/en/nsmp2inf.cab#Version=5,1,52,701' standby='Loading Microsoft Windows Media Player components...' type='application/x-oleobject'> <param name='autoStart' value="false"> <param name='uiMode' value="invisible"> <param name='loop' value="false"> </OBJECT> I'm calling in JavaScript: MS_mediaPlayer.URL = "SomeAudioFile.mp3" MS_mediaPlayer.controls.play(); When I look at Fiddler I can see that the player actually downloads "SomeAudioFile.mp3" twice. Is there some setting I have wrong? I was trying to set the "autoPlay" to true and avoid calling "play()". Got the same result - two downloads. UPDATE: The first request's user-agent is "Windows-Media-Player/11.0.5721.5268". The second has "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; GTB6; .NET CLR 1.1.4322; .NET CLR 2.0.50727; .NET CLR 3.0.04506.30; .NET CLR 3.0.04506.648; .NET CLR 3.5.21022; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729)". Looks like the browser is running the same request the second time. No Idea why Any ideas? UPDATE (4/1/10): Still no solution. I debugged the JS thoroughly and there is only one call to MediaPlayer.URL='.....' to set the audio file. Nothing else triggers the media player to load the file and there is no other place referencing the audio file on the page. One other interesting fact is that this doesn't happen (the double loading of the audio) when I run the browser locally on my development web server. But other remote requests to the same web server generate the double audio loading. I believe I eliminated any correlation with specific IE version or media player version. This happens with IE6-8 and WM9-12

• VS2010 Developer Image

  - by David Ward

  I am about to create a new developer PC image for developing WPF applications using VS2010, WCF, SQL2008 and SharePoint2010. What OS should I opt for? Windows 7? Windows Server 2008 R2? I'd have thought Windows 7 to make sure that I have a similar experience during development as an end user, however I can't install SharePoint on a client OS and so thought about Windows Server 2008 R2 to help with the SharePoint development process. Thoughts?
