Thanks -Sivaraman Latchapathi DO you need an explanation on the for part name or any insights of the OLEDB provider THe four part name is nothing else than the full declaration of the aquirering object: ServerName.DatabaseName.SchemaName.Objectname The identifiers may vary from source system to source system as there is something like a library in DB2 You probably would have to combine the dateparts to a complete date to keep the logic of comparing a date, so it would have to be something like: HTH, Jens Suessmeyer. --- http://www.sqlserver2005.de ---- ...Show All

• Audio and Video Development NamedNodeMap Interface ( usage guidelines)

  Hi everbody The DOM Level 2 Spec (page 44) defines NamedNodeMap Interface but it does not give a method to create a NamedNodeMap. So the only use of NamedNodemap is through the Node interface where we have a member variable : NamedNodeMap atributes; ie the attributes belonging to a node can be assumed to be stored in a NamedNodeMap. ------------------- The questions are : 1. Does all the attributes (specified or non-specified(ie those having default values)) belong to a node's NamedNodeMap 2 . The NamedNodeMap Interface has method item() (Refer Page 44 DOM Level 2 Core Specification ). Quoting the spec : The item() returns the indexth item in the map.If index is greater than or equal to number of nodes in the map ,this returns NULL ...Show All

• Visual Studio Team System Team Foundation Server - Deleted project asks to unshelve...

  Hello! From VisualStudio .NET, I right-clicked on an open solution and added the solution to source control.

• Game Technologies: DirectX, XNA, XACT, etc. Elapsed Timer Inconsistant?

  In working on my game I developed a throttler that runs off of elapsed time to handle problems I was having using keyboard input. Basically update and draw were appearing to detect the keyboard keys multiple times for each keypress (I am using the Input code from the spacewars demo). The problem is about every 4-5 seconds or so the elapsed time apears about double the float value it does every other time. Tracing out the data it seems most changes to the elapsed time run around 0.0125 seconds, with the occasional 0.025 second spikes. I know we are talking fractions of a second here, but the reusult is every once and a while I still get multiple key presses detected, and upping the threshold doesn't help until I move up to 0.5 second ...Show All

• Windows Forms Switching between Console application and Windows Forms applications

  I was hoping to write a single application that can behave as Console application if specific run parameters are specified and behave as Windows Forms application otherwise (of course without the Console). For example: public static void main(string[] args) { if(//check if args has specific run params) { //do stuff Console.WriteLine(//results); return; } else { //Show nice form and all that } } Couldn't find any pointers as to how to achieve this.
