• SQL Server How to control visibility of table columns at runtime?

  Hi all.. Using ReportViewer in an ASPX page, is it possible to hide certain columns of a table at runtime That table is databound to a business object and I'm using local reporting capabilities of Visual Studio 2005. Thanks Jaime I assume you are using a "table" reportitem. In report designer you can select the entire column of a table. In the properties window (F4), you should then see a "Visibility" property. You could set the Visibility.Hidden property to e.g. =Parameters!HideColumns.Value (assuming HideColumns is a boolean report parameter). -- Robert ...Show All

• SQL Server SQL Server 6.5 - 2000 Upgrade Tips

  Im currently in the process of upgrading a mission critical financial database from 6.5 to 2000, and i thought while i come across some problems I might as well post them here in case anyone else needs some help.  I found there wasnt much material out there that supplies all the anomolies between 6.5 and 2000 so this post might be of some use.  Mods might want to make this a sticky Anyway first thing is the treatment of NULL's this is a simple one! Bascially 6.5 will treat NULL's the same everywhere i.e. this example will work in 6.5 if @var is NULL IF @var = NULL     <do something> depending on whether AN ...Show All

• SQL Server Passing Multivalue Parameters Through a Report Link

  I've created a line chart in my report which lists number of transactions by month. I've also created a report to list transactions by day. My goal is for the user to select a month and link the report to the graph with the selected month divided up into days (in other words, the user wants to see the number of transactions for each day in the selected month). Anyway, everything is working perfectly except for one thing. In the list of parameters that I am passing to the report for each day, I want to pass a multivalue parameter which contains all the transaction IDs the user selected in creating the report (these are supplied by a multiv ...Show All

• .NET Development Delay

  What command in C# make a delay in program (like Sleep() in C++) What are you trying to achieve with the Sleep Although, you can sleep the current thread via Thread.Sleep, doing this on the main thread is typically a bad thing as this will prevent Windows messages from being processed, and to the user it will seem like your application has locked up. If you are using this in a Windows Forms application, it is probably better to use a Timer class. ...Show All

• Visual Studio MSBUILD (publish – click once) RC on build server

  I am trying to get our build server working with the RC of .NET v2.   With beta2 I could make use of MSBUILD just by installing the Runtime and the SDK on the build server.     (I do not like having to install Visual Studio on the build server.)   When the RC there does not seem to be a SDK, what do I need to install on the build server so that I can build using the RC version of MSBUILD, including “publish” for “click once”.    I have installed the “Run time” that I found on the RC DVD image but that does not seem to be enough for “publish” is it ok for basic compiles.   (We need to test out our ...Show All

  Is it possible to make a program as a Microsoft Windows service I need to know, and now that I look, it isn't available in the express edition. Ouch. . . you might be screwed here. . .
