• SQL Server Report subscriptions

  Is there a way to either query the ReportServer database or view a report within Reporting Services to show all the subscriptions and their next run time The "My Subscriptions" area only shows when a report was last run for subscriptions I created. Since we'll end up moving dozens of reports from Crystal to SSRS and multiple people will be creating schedules, it'd be handy to have a nice list displaying exactly what's scheduled and when they'll run next. Any ideas are greatly appreciated. Thanks You would have to create an user interface to pull the data from the SQL Server Agent for this.

• .NET Development Trusted_Connection Problem with VS2005

  I'm sure this is a known problem, but I can't seem to find the fix. My VS2005 app connects to the SQL Server database through web services. If I connect with a connection string that uses userid and password, no problem. But, if I change that to use a Trusted_Connection instead, it won't work. This worked fine when the app was compiled under VS2003, but has not since migrating it to VS2005. Is there some setting I need to tweak somewhere In IIS maybe TIA, I don't think the Anonymous access matters ... users are authenticated with logins and passwords stored on SQL Server through an application login screen. This wouldn't be the cause of my problem anyway, would it ...Show All

• Visual C# VB6 ActiveX Dll Problem !

• .NET Development IpcClientChannel and [OneWay] methods

  It seems to me that IpcClientChannel doesn't really support one way calls. The channel waits for a response on these calls (not sure why) and the response never comes. So a worker thread is blocked on every call. I'm not using security, just the basic setup (on XP SP2). Yes this is a bug in the IPCChannel. It should be fixed in the next release. Unfortunately the only workaround for now is to not have the OneWay attribute. I will post here if I can come up with something better. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. General Audio Disfunction

  After about 10-15 minutes of gameplay, the audio slowly begins to become more and more distorted and fractured sounding. Both the sound FX and BGM gradually become more choppy and grainy sounding while dragging down the overall performance of the game. Any ideas my code for audio is pretty straight forward. My general routine for calling sound FX is; 1) call 'cue stop' in case the effect is still playing 2) call 'get cue' to retrieve the sound again 3) call play I do this in most cases where I only want one instance of the effect occuring at a time and there is a chance the sound will not have finished playing before it needs to be played again like in the case of a rapid fire weapon. ...Show All

• SQL Server Dynamic query

  Hello I have a problem with writing a query.Let me give an example: Table: ColA , ColB , ColC , Col1 , Col2 , Col3 , Col4 , Col5 Ok.I must write a SP and it gets a parameter,say @param. if @param=1 then in the select statement I will select Col1,if @param=2 then I will select Col2 and so on. How can I do this Thanks. Joey gives an answer how. You could also do: declare @query varchar(max) set @query = 'select col ' + cast(@param as int) + ' from table' Or if the column names aren't actually numberd, use a CASE expression to pick the columns. The question I have is why do this If all columns are only useful one at a time, this is probably a design issue. If this is to support some use ...Show All

• Visual Studio Express Editions best way to find all if webbrowser is totally ready

  I am trying to automate saving data from browsing some websites. I am having great difficulty to judge whether the webbrowser has completed all frames and becomes ready.

• .NET Development Deserialize - unable to find an Assembly .....

  Hi, I've got a really strange error. I'm using a fairly standard method to implement the IClonable interface, basically I serialize my object to a memory stream and then stream it back again. This all works fine in the .Net runtime environment and if I use a test application. However, I need to run as a COM control inside of an HTML page (long story, but I am embedding it in the home page pane of Outlook). Anyway everything works fine except this routine. It fails when trying to deserialize with "Assembly not found". I added some debug code to load the assembly dynamically and that all works fine. It can't be a version issue as I am serializing and deserializing the same object in the same method. I've traced where the framewor ...Show All

I am not able to get the Certificate Authentication Scenarios to work with Simple STS as well. It seems like the problem stems from the Cardspace Agent UI itself.
