• Game Technologies: DirectX, XNA, XACT, etc. input strategy

  Is getting a input device state heavy Should I only do it once per tick and save the info to some global variables that the rest of the of the program can access. Or can I use GetState() everytime I need to check the state of a input device Its probably a good idea I also made an input state manager (InputStateTracker) so I only call GetState() on mouse and keyboard once per frame as I am also using an action mapping implementation where you can map the input to enums of actions, and it got out of hand with all the GetState() calls I had :P ...Show All

• SQL Server Able to run packages outside Designer, but not one containing FTP task

  Hi. I have read most of the threads on not being able to run packages outside the Designer, in Agent. I believe my problem is different: I am able to run some packages with Agent. In fact, we have a couple scheduled and running every night. However, when we try to run a package that contains an FTP task it only runs in debug mode. If we import it into our server or run it without debugging it keeps failing and giving us the now famous: The task...... cannot run on this edition of Integration Services. It requires a higher level edition. So, we have some packages already scheduled and running, but we can't run this specific package with the FTP task. We (two of us) have created this package in the same way we created the other o ...Show All
