• Visual Basic Pipe Buffer

  Hi All:  Is there a buffer in vb2005 that can write to and read to. After a record is read, it will be removed from the buffer, like a pipe   Thanks. Hi, There's several things within the .net framework that you can use like that, depending on your intent. You use an arraylist, a collection, any number of things. If you want to put things in and get them out in the same order, have a look at the queue class (System.Collections.Queue). If you want get them out in reverse order, the Stack class would be better. Also, make sure you check out the generic versions of the classes (Syst ...Show All

• SQL Server Differences between MSDE and SSE2005

  Good Afternoon, Everyone. I know SSE2005 is built on Sql Server 2005 and MSDE was built on Sql Server 2000 so let's not start a thread discussing that. My question is more about the concurrency governor found in MSDE. I've heard people talking about the concurrency governor in MSDE being removed in SSE2005. Instead, performance is limited by the server configuration; one CPU, 1 GB RAM, and a maximum 4GB database. Can anyone confirm this What happens if the server has 2GB of RAM and/or dual processors Will SSE only utilize 1 GB and/or one of the processors Thanks for the help, Scott You assumptio ...Show All

• Visual C# How to assign 4 bytes of float to byte array

  I need to assign each of the four bytes of a float type variable to four bytes of a byte array. Can someone suggest a way to do this In essence I would like to do this: byte_array[0] = float_byte1 byte_array[1] = float_byte2 byte_array[2] = float_byte3 byte_array[3] = float_byte4   This array will be sent via a USB transaction. On the other end I will need to re-assemble the float type variable... BitConverter.GetBytes () will convert a value to its bit equivalent.  You'll need to verify the ordering is correct but it should be. Michael Taylor - 11/23/05 ...Show All
