  Hello everybody, I am wondering if it will be made possible to develop other version of LINQ, using data sources other than SQL or XML. I mean, are there any plans for making appropriate APIs public Tom Jastrzebski This is absolutely possible Tom.  As a matter of fact XLinq and DLinq are just using the extension mechanisms made available by the LINQ technology.  Take XLinq for example.  There are two main ways that XLinq works with the underlying LINQ technology to provide XML Query and Transform capability.  One, have all of the appropriate methods return IEnumerable<T>.  For ...Show All

• SQL Server Souce and Dest auto-mapping

  Hi, in my package there are several Connection Managers linking DB2 databases and there is one "fake" CM which copies the connection string of one of the other "real" CM depending of the need. Then I've made a Data Flow containing an OLE DB Source and a Destination Adapter. The Destination has a "table name from variable" access through a fixed Connection Manager, and the Source has "sql command from variable" access and uses the "fake" Connection Manager, which has "inherited" the connection string from one of the "real" CMs. The point is: When I drag the arrow from the OLE DB Source to the Destination, some mapping metadata are set, and th ...Show All

• .NET Development Using FtpWebRequest to check if a directory exists.

  I'd like to know if there is anyway i can use the FtpWebRequest class to check if a directory exists before creating it on the server. The reason i ask is because if you try to create a directory that already exists it throws a WebException and disconnects from the server. This gives a performance hit if we are trying to create alot of directories on the server that already exists due to the disconnects/reconnects. TIA, lushdog Yes, you can set the FtpWebRequest.Method to "NLST" and use it to check if the directory exists on the server Mariya ...Show All

• Visual Basic Rotating an image or bitmap object

  Hello, I'm looking to (through code) rotate an image or bitmap object. It has to be to any angle, too, not just 45 or 90 degree intervals. I HAVE code to do this, however, the centerpoint for rotation ends up being the top-left corner of the bitmap. I need it to rotate from the centre. Thanks in advance to anyone who can help. You need to do a translate transform by half the width and height of the bitmap, so that the point of rotation is the very centre. Then translate back when you've rotated it. ...Show All
