• SQL Server Using expressions in other expressions in SSRS 2000

  All the other reporting tools i've used have the ability to give the result of an expression (formula or calculation) a name (or load it into a variable) and include it in another expression (formula or calculation). I can't find this functionality anywhere in SSRS 2000, does it exist Thanks. You can create either a calculated field ( http://msdn2.microsoft.com/en-us/library/ms345330.aspx ) or a textbox that ...Show All

• Windows Forms Getting Notification when a Controls Screen Position is Changed

  I need to get notification when a controls screen position has been changed, the only case that I am not able to handle is when the controls screen position is changed due to the user moving the window. I've tried catching the Move and LocationChanged events for the form itself (using MyControl->TopLevelControl += gcnew System::EventHandler (...) but I only get the event when the window is initially constructed.

• Game Technologies: DirectX, XNA, XACT, etc. Does DirectX have the OpenGL equivalent of Display lists?

  As the subjects asks, is there an equivalent  feature in DirectX Basically I want to just render about 200 spheres most of which will be the exact same copy of each other. Drawing each sphere independently of each each other gave quite poor performance in OpenGL until I used Display lists which enabled me to save a fixed set of drawing commands and just call the display list instead of redrawing the sphere each time. ...Show All

• Software Development for Windows Vista Is WF right solution for high-throughput OLTP?

  We are considering re-implementing the core of our OLTP (on line transaction processing) app using WWF.  Having worked with WWF for awhile now, I've concluded it meets our needs very well for flexible loosely-coupled messaging with contract-based binding of endpoints.  One area still concerns me, that's performance. Our input to the WF from host is a message object, and we pull the modified object back to the host a ...Show All

• Visual Studio Express Editions Newbie: tyring to use numbers in a textbox
