• SQL Server ADS: Sample application cannot access desktop database

  The sample application provided with Access Database Synchronizer fires a "A request to send data to the computer running IIS has failed. For more information, see HRESULT." exception on my WinCE 4.2 device. I debugged it with VS2005 to see what was going on and found that the problem resides in the line: m_connDesktop.Pull("MSysObjects","SELECT Name FROM MSysObjects WHERE Type=1 and flags=0",accessSysConnectString,RDATrackOption.TrackingOff,"Err_MSysObjects"); It seems that connection m_connDesktop is ok but calling Pull method fails. I've verified that SSEvAccessSync service is started when ActiveSync detects device connection and that firewall rules are correctly updated. Also, i ve ...Show All

• Software Development for Windows Vista Packaging: "[Content_Types].xml" part?

  I'm messing around with the packaging APIs (my eventual intent is to figure out how to add my own custom parts to an existing XPS file, since MS isn't telling). I started with the PackageRead sample, and made some adjustments to basically take a .XPS input and dump it to a flat-file structure. I'll know when I have it right when I can take any of the sample XPS files, dump to a folder tree, manually re-Zip that back to a .XPS and get a faithful reproduction. It's mostly working, except some sample XPS files have a [Content_Types].xml file in the package root. But for whatever reason, none of the Package collections (Parts & Relationships) seem to recognize the existence of this. So I have two questions: 1) Anybody know how to get at th ...Show All

• .NET Development ArrayList missing .Item???

  I know this has got to be in FAQ someplace but I can't find it, and it's driving me nuts... Every reference I find says that there's a .Item property for ArrayLists. But my .NET 2003 C# programs won't compile if I try to reference that property. For example: ArrayList MyList = new ArrayList(); Object o = MyList.Item[3]; I get a compile-time error: System.Collections.ArrayList does not contain a definition for "Item" Thanks for any help you can provide... In both .NET 2003 and .NET 2005 ".Item" will not be there in ArrayList. The code ArrayList MyList = new ArrayList(); Object o = MyList.Item[3]; will through compile-time error: y ...Show All

• Visual Studio 2008 (Pre-release) Sometimes MediaElement plays streams without sound. Bug ?

  I've been using MediaElement to play WMA audio streams. I use only one instance of MediaElement: <MediaElement Name="mediaElement" LoadedBehavior="Manual" Stretch="Uniform" HorizontalAlignment="Left" Width="83" Height="Auto"/> and I access this instance from code so that each time the user chooses a URL here's what I do: mediaElement.Stop(); mediaElement.Source = uri; mediaElement.Play(); Volume is always set at 0.5f and Mute is never set to true. About 1 out of 10 urls plays with no sound. I know it's playing because I not only received the play event but also see that the Position is increasing. This happens independently of the URL. However, I never have the problem ...Show All

• SQL Server LEAVES function causing problems in MDX Script

  Hello, Got a bit of a weird situation here and I'm having trouble fathoming it. I have a cube with a dimension called [Currency]. I have a MDX Script which contains the function call: LEAVES([Currency]) And up until this afternoon everything was getting processed fine. Since then I introduced a new measure group that does not include [Currency] and still everything is getting processed fine. I then added another measure group that, again, does not include [Currency]. I am now getting a processing error on my second new measure group: Leaves function for attributes with mixed granularity in different measure groups is not supported. I think I can kinda work out why I'm getting the error - its because the LEAVES function ...Show All

• Visual C# is as Keyword

  I have a general event handler function. and has a general object passed to it, but I have to use a "is" or "as" to decode the type, is it possible that the base class can detect the type and call the function for that type I don't what to use methodinvoke because it is so slowwwwww. Another apporach would be to anonymous delegates would help but I don't like putting several delegates in one method to handle each type.. and I would have to use continutions to continue the event pump... (ie see robots framework for an example) And I don't want to declare delegates for each type because this means more work for the programmer... void handler(baseobject ev){ if (ev is MyEvent) { MyEvent evmy= (MyEvent)ev); ...Show All
