• Visual C# Fast searching of a byte array

  Can anyone provide guidance on what would be the fastest method of searching a large byte array for some particular sequence of bytes I know I could convert it to a string and do an IndexOf but I would like to avoid that. Any ideas if you were looking for the bytes 03 02 01 in the following array: 01 01 02 02 03 03 03 02 01 01 01 02 02 02 03 03, if you sorted that array looking for (also sorted) 01 02 03 you'd now not find any matches in: 01 01 01 01 01 02 02 02 02 02 02 03 03 03 03 03 ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Are multiple SpriteBatches necessary?

  I"m currently working on a tile-engine demo, and a single spritebatch all of my drawing. Are there any advantages to using multiple spritebatch objects If yes, what is the criteria for determining how to break it down Using a single spritebatch should generally be fine. The main issue to do with sprite performance is how many times you call begin and end on the batch, and the sorting of your sprites within each batch. For optimal speed you should use a single begin/end pair for as much drawing as possible, and within that block, draw sprites ordered by their texture. If that's hard for you to achieve, you can tell the sprite batch to sort them by texture for you (but that might be slower ...Show All

• Windows Live Developer Forums Virtual Earth 3d install

  This may not be the place, but I can not find help anywhere for my problem. The Live.Mail group referred me here. My problem is that when I open and select the 3d map, the 3d objects are represented by a blue silhouette and never fill in the object. I went through the acceleration settings, FAQs, etc. to no avail. I am running XP Pro, IE7, 3.2 GHz P4 CPU, 1 mb ram. When I originally installed VE, I had my default browser set to Firefox 2.0. I reset my browser to IE7, uninstalled and reinstalled VE. I saved it to disk, also ran it from the site all to no avail. During the original installation, I also installed Live Local for Outlook. This seems to be OK so I left it as is. I noticed the map was taking a minute to load ( I have 768 kbps DS ...Show All

• SQL Server Merge agent login problem

  I have a push merge replication up and working in development SQL Server 2005 (publisher) and SQL Express (subscriber). Because the upgrade from 2000 to 2005 for our production servers has been delayed for who knows how long, I am working to set the same replication up with 2000 and MSDE. The merge agent is failing in 2000 with the error: Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection. (Source: MSSQLServer, Error number: 18452) The 2005 merge agent runs fine. I think it is because the 2005 subscription wizard allowed me to set the 'Run as: SQL Agent Service Account' option, instead of a windows authentication uid. There is no opportunity to set this in the 2000 subscription wizard nor o ...Show All

• SQL Server datatype map - Native ODBC driver

  Hi, Our software uses native ODBC driver and Visual C++ 2003 to communicate with SQL Server 2005. SELECT xml_schema_namespace(SCHEMA_NAME(schema_id) ,name) FROM sys.xml_schema_collections. SQLDescribeColW returns -152 as the datatype for the column in the above select statement. However, I’m unable to find a preprocessor definition for -152. The datatype looks like an nvarchar. Is it an nvarchar Where can I find the definition for this datatype I have discovered similar problems while bringing back SQL_VARIANT types. The returned subtype of a SQLVariant comes up with -16 and -25. I cannot find definitions for these sub types either. Any help is appreciated. Regards, Venkat ...Show All

• Visual C# Mathematical question !!

  Hello, Can any one sort this complexity from worst to good O(k) O(k n) O(k n2) O(k 2 n ) O(k log n) O(k (log n) 2 ) Thanks a lot Why does this sound a lot like a homework question The best way to handle this is to substitue real values for K and N, and see what numbers you get. K is a "Konstant" and for large values of N, becomes irrelevant, so we can use 1 for K. N will vary depending on the data the algorithm is to process, so just pick a suitably high number of N. 100 should do. THen just order the list. "Worst to best" would be Highest to lowest. O(k) = O(1) = 1 O(k n) = O(1 * 100) = 100 You are on your own for the rest. ...Show All
