In the "USB series three", we implemented a series of SCSI commands, in this series, we want to implement the command to write sector to the U disk, so this article is relatively easy, more is to give a realization of the source program.In the third USB series, the SCSI commands we implement are: INQUIRY, read capacity (10), TEST UNIT ready, REQUEST sense, read (10), all the commands that are read out, so it doesn't break the contents of the USB stick, on page 29th of document

One: Why use a function, the function of the definition of the format1, if there is no function, then the written code will be reused, and the readability is poor.2, function format :def func (x): def is a keyword, you must define a fun function name (to have a meaning) (x) parameterthe func () function name + () represents the execution of this function .3. When using a function, be aware that the function is function-oriented and that there is no print inside the function as far as possible.
SqlBulkCopy class is System.Data.SqlClient under the class, we are not used in development, and even do not know that there is such a class exists, but it is more than SQL INSERT, transaction BULK INSERT, SQL bulk splicing is much faster than the call stored procedure insert ConvenientHere's how to use it:public static bool Executetransactionscopeinsert (DataTable DT, int batchsize) {
int count = dt.Rows.Count;
string tableName = "TestTable";
int copytimeout = 600;

Actual environment topology diagram:
In general, FreeSWITCH uses the SOA pattern by default, and in some cases the non-SOA model.
Non-SOA model, what can cause problems. will result in a SDP address error, resulting in a voice single pass.
Through the topology map can be seen, FreeSWITCH is a dual network card server, the actual environment, the intranet IP phone call, two-way voice normal, both sides can hear each other speech.
But in the case of phone calls (mobile phone calls in), bridge or
1,Data Loading Problems:
Any system cannot do without data loading. Below we will list several common data loading methods in AE. For reference:
1Load the personal database
A personal database is a database stored in Access. There are two ways to load data: by name and by attribute (maybe more than these two ways, AE can implement the same function in multiple ways ).
AAnd load the personal database by setting properties.
First passIPropertySetThe interface defines the relevant attributes of
then →save as (Save As) by selecting filecommand to save it with another file name (for example, save as Test.cpp name), thus generating a new file test.cpp.It is convenient to use this method, but it should be noted that:(1) When saving a new file, do not use File→save (save) operation, otherwise the original file (Cl-1.cpp)The content has been modified.(2) before compiling a new file, you should first select the file →close Workspace (Close
OLAP options in Oracle9 I Database Release 2 introduce the analysis workspace and truly integrate the relational and multidimensional data types in the same Database. So far, the only way for developers and DBAs to use the analytic workspace is to use command line API calls to manually build them. However, with the latest Analytic Workspace Manager (AWM) version,
You can restore a panel by storing its current size and position as a named workspace, even if the panel is moved or closed. Name of the workspace that is stored
