• Game Technologies: DirectX, XNA, XACT, etc. retrieving more than 4 values per texture lookup

  Is it possible to have a texture with more than 4 values per texel My problem is, I need to look up a chunk of many values (about 16) multiple times per pixel and I like to do that quickly. In my setting more than three 2d texture lookups each time (= 12 float values) is the maximum I can allow without a significant performance drop. Also if anybody has experimented with 64 or 128 bit textures I'm interested to know about the performance of a lookup compared to a 32 bit tex lookup. Maybe it is reasonable to pack more values into those larger formats If that is possible at all. Nico No, you can’t g ...Show All

• Visual FoxPro function argument is invalid...

  I have a problem with this message and a few similar once. When I get it I invoke the debugger and attempt to examine the variable/argument. In this particular case it is a memner of an array. I suspect that instead of a character string it got an .F. value but it is hard to prove because I cannot examine it. If I attempt to look at it in Command Window I will get the same message that it is invalid. More than that, some other related, neighbouring variables become shielded as well. If I try to examine them I get the same message. Is it a particular anomaly of my setup or a universal problem Can anything be done about it Thanks. Hi ...Show All

• SQL Server controlling security through stored procedures -- 2005 behaviour

  Hi! I'm trying to control security through sps -- meaning execute permissions are granted on stored procedures, and no users have read/write permissions on tables, etc directly. Which works fine as long as all objects referenced are in the same db as the procedure. An issue arises when a stored procedure accesses a table in another database: Getting a : Msg 229 SELECT permission denied on object 'blah' Even though the procedure is created by sysadmin. Has this changed since 2000 I'm pretty sure in 2000 it would've worked as the sp would be executed in sp owner's security context. Moreover, when I try to use EXECUTE AS in the sp as ...Show All

• Visual C# Generics C# Matrix

  I was about to design a Generics C# Matrix in this way: public class Matrix < T > {        List < List < T >> _data;        .... } Many issues made desirable in this case, constraint the type T to be a numeric base type. Let's say, int, long, byte, float, double... But I really couldn't find the legal way to add such a constraint. The question is precisely that: How do I constrain the generic type to a numeric base type This is just an admirable and elegant solution. Is very clean and recursive. I wish I could imagine it before! ...Show All
