• Visual C# issue converting generics list to array and back

  I'm new to generics and they are being a real pain when it comes to my web services. I've got a winforms app that uses a proxy web class which invokes methods on a web service. The web method "RemoveRole" takes a parameter of List<Guid>. It throws up saying it could not convert object[] to List<Guid> so I'm trying to figure out how to put the plumbing in place to make the conversion happen. Currently the code below throws " Cannot implicitly convert type 'System.Collections.Generic.List<object>' to 'object[] ". 1. How do i get the following to work and.. 2. What plumbing do I need in the web service code to convert from object[] back to List<Guid> public void RemoveRole(List<Gu ...Show All

• Visual Studio Express Editions File Associated Icons WITHOUT passing File Name

  Spent 2 days on ShGetFileInfo - and was not satisfied. How can I get the Icons associated to a file type based ONLY on the extension I am building a catalog application which may contain a file "C:\TEMP\DATA.TXT". This path/file may be valid on my computer but not on another. However, I need to display the TEXT FILE associated icons irrespective of where I load the "catalog". Can anyone provide some code to do this effectively using the "System Imagelist" or any better implementation Thanks. Reading the docs, it looks to me like you can pass the SHGFI_USEFILEATTRIBUTES flag and pass a fake file name like "blabla.txt" or ".txt". Pass FILE_ATTRI ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Help Using Quaternion To Find Target

  I've read a couple of very helpful threads here on Quaternions, so I decided to try putting them to use. I was able to use them to move a 3D object around using a modification of Riemer's flight simulator tutorial, to which I added a second object. However, I then tried to initialize the orientation of the two objects to point towards each other from any given starting location, and that didn't work the way I expected. Can someone help me understand what's wrong with the following code public void SetOrientation(Vector3 startLocation, Vector3 targetLocation) { Matrix target = Matrix.CreateLookAt(startLocation, targetLocation, Vector3.Up); Orientation = Quaternion.CreateFromRotationMatrix(target); } public virtual void U ...Show All

• SQL Server Implementing "preconditions"

  I have about a half-dozen insertion tasks that depend on a condition: SQLServerProcessDate == OLEDBprocessDate. If the task executes early, old data gets inserted and needs to be backed out later on. (This happens about two-three times a month.) The jobs start at 8:00 PM, but on occasion processing runs late. In order to make the task intelligent enough to not insert old data, I've thought of a couple options: 1.) Separate scheduled job runs continuously, comparing process dates. When the dates match, it sends a message to the other jobs. Pro: less repetitive. Con: another scheduled job ! I'll have to learn the message queue task; a little bit complex; flood of database activity on message reception may slow system down 2.) Compare the dat ...Show All

• SQL Server SSIS Logging -- how to overwrite old log file.

  After logging is configured in SSIS package, it seems that after each execution the output is appended to the log file (we are talking about log provider for text files in this case). As a result the file just keeps on growing. I would like to overwrite old information with each run, but I can't find where to configure this. Anybody knows Thank you! I don't think you can do that but you can easily just create a new file upon each execution by setting the name of the file dynamically. If the filename contained (for example) the start time of the package then you would get a new file on each execution. If you want to do this - explore the use of expressions. -Jamie ...Show All

• SQL Server OLAP Cube from an OLTP (normalized database)?

  Hi All, I am new to OLAP and every book that I have read so far talks about creating an OLAP cube from a Star Schema (Data warehouse). I want to ask that, is it possible to create a Cube in Analysis Services from an OLTP (normalized database) without creating any star schema I understand that the first concern is performance. Regards, Ravi S Thomas, Thanks a lot for the pointer and recommendations. As you mentioned one can use named queries and data source views.

• Game Technologies: DirectX, XNA, XACT, etc. Whats the deal with DirectX being owned by XNA?

First DirectShow goes. Now I realize even basic support I had in DirectX 9.0c is not even supported in DirectX 10.
