• SQL Server The product level is insufficient for component when executing package using C# code.

  Hi, I have created a Integration Services package that takes a table in a database, and transfers it to a flat file. This package has successfully run through visual studio 2005 as a .dtsx package, and given the output that I expected. However, now, I am trying to excecute the package (as xml) using C#, and I am receving this error: Error in Microsoft.SqlServer.Dts.Runtime.TaskHost/DTS.Pipeline : The product level is insufficient for component "Flat File Destination" (31). I do not understand how a working package would have this kind of error. Considering that it runs when I do not use C# code to execute the package means that I have SSIS properly installed, and I have the proper versions (or it should not execute ...Show All

• Visual Studio 2008 (Pre-release) Animation Exception thrown seems wrong -

  mStoryboard.Seek( this , TimeSpan .FromMilliseconds(0), TimeSeekOrigin .Duration ); (SkipToFill doesn't work either) I Created a project in Blend, added a 10 second, 10 frame vid - each frame has 1 digit 0-9. If I pull the storyboard from the resources and do a Begin/Stop sequence and then run the above line of code I get the exception: "The ClockController.Seek method was called using TimeSeekOrigin.Duration as the seekOrigin parameter for a Clock that has a duration of Forever. Clocks that have duration of Forever must use TimeSeekOrigin.BeginTime." The storyboard and MediaTimeline are not DurationForever or RepeatForever. Also - to use TimeSeekOrigin .BeginTime I need to know the duration and I have no easy ...Show All

• Visual Studio Express Editions More control over balloon tips?

  Hi all. I'm using notifyIcon->ShowBalloonTip to have a balloon tip appear near the systray, pointing at my notify icon. But the notifyIcon object has just icon, title and text properties for the balloon tip. What if I want to add a little button in the tip Also, the balloons have a timing which is mainly governed by the system (min/max values imposed, time stops if the user is idle): what if I want to control the exact time at which the balloon will close I suppose the whole thing could be coded from scratch, but is there a simpler way Or maybe some free code availaible Thank you, Frank. The balloon tip implementation of the NotifyIcon control doesn't let you do these things. You'd have to ...Show All

• Windows Forms Serious problem with Tooltip in ListView in VS2005

  There seems to be a problem in VS2005 (which was not present in VS2003) when a tooltip is assigned to a listview. If the mouse hovers over a blank area of the listview it works fine, but if it hovers over a populated row the tooltip shows very briefly - not long enough to read - and then disappears. To make matters worse, for some reason a tooltip generates a MouseMove event when it disappears (even in VS2003), which causes real havoc in a program that uses the MouseMove event to set the tooltip text, because setting the text causes the tooltip to be redisplayed. When the cursor is over the blank area there is no problem, the tooltip disappears after the AutoPopDelay time (usually 5 secs) and is immediately redisplayed (VS2003 also behaves ...Show All

• Internet Explorer Development IE7 issue with Integrated Windows Authentication in IIS

  Hi, I've a web application developed in ASP.NET which is hosted in a Windows 2000 server with only Integrated Windows Authentication enabled. This is to make use of Active Directory Services. Now, everything works fine with IE6. But in IE7, I get the Page Not found message.

• SQL Server SqlExpress Bootstrapping

  Hello I'm building an app for retail commercial distribution, and I'm agonizing over which database to use. I'd like to use SqlExpress, as it's supported by the code generation tool I use, but I'm wary of the download size.   SqlExpr32.exe is 35 megabytes, yet Microsoft maintains that it's a " fast download ", a claim whose logic escapes me. If I try to force something like that on my buyers, I won't have any buyers (Framework 2.0 is going to be hard enough for them to swallow).   I recently made the difficult decision to forfeit the use of my preferred code generator ( DeKlarit ) in favor of the VistaDB embedded database , but this article has got me thinking about SqlExpress again.   Is there a lightweight distributi ...Show All

• SQL Server sql2005 Query Editor and sql logins

  Under sql 2000 I could connect to a server as a speciifc sql user. How can I emulate that under sql 2005 Query Editor. (It doesn't appear to let me define the user to log in as.) TIA, Barkingdog When you click the connect button you should get a dialog asking for connection credentials. Also, in SQL 2005 if you are an admin you can change the execution context in-line by issuing EXECUTE AS login='name of login' and use REVERT to go back to your original context. ...Show All
