Simple ASP. NET message Book Development Tool: vs2005
  1. Data logging Design

    • Create a data volume named webtest
      The SQL statement is as follows:
      Create Database webtest
    • Create a table named Databook
      The structure is as follows:

      Data Table Name ‑ Response Contains the delimiter
      Databook Accounting Basic Subject Assignment Region name Response Struct type Bytes size
      ID Bigint 8
      Topic Nvarchar 50
      Name Nvarchar 10
      Body Nvarchar 200
      IP Datetime 15

      The SQL statement is as follows:

      Create Table Databook (ID bigint identity (1, 1) Not for replication, subject varchar (50), name varchar (10), body varchar (200 ), IP varchar (15),) insert Databook select 'Broken content', 'Broken into reference', 'allowed internal content', '1970. 0.0.1 'Union all select 'random latest', 'Broken bytes latest', 'random bytes content', '100. 0.0.1'

  2. Leave a comment
    • Use the Response Message Interface Design
      Create a new guest. aspx file. The HTML generation is as follows:

      <% @ Page Language = "C #" autoeventwireup = "true" codefile = "guest. aspx. cs" inherits = "_ default" %> <! Doctype HTML public "-// W3C // dtd xhtml 1.0 transitional // en" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <HTML xmlns = "http://www.w3.org/1999/xhtml">

  3. View hosts
    • View Plane Design
      Create a new see. aspx file. The HTML generation is as follows:

      <% @ Page Language = "C #" autoeventwireup = "true" codefile = "see. aspx. CS "inherits =" see "%> <% @ import namespace =" system. data "%> <! Doctype HTML public "-// W3C // dtd xhtml 1.0 transitional // en" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <HTML xmlns = "http://www.w3.org/1999/xhtml">

  4. Web. config file replacement
    <? XML version = "1.0"?> <! -- Note: In addition to manual debugging, you can also use web management tools to set the value of your application. Select [website]> [ASP. NET Organization] in Visual Studio. If you need to complete the configuration and clarification form, please test the machine. config. comments (usually in \ windows \ Microsoft. net \ framework \ v2.x \ config) --> <configuration> <etettings> <add key = "connectionstring" value = "Server = 210.1.1.22; database = webtest; uid = sa; pwd =; "/> </appsettings> <connectionstrings/> <system. web> <! -- If compilation DEBUG = "true" is set, the operator is inserted into the hidden plane. Because this affects the performance, this value can be set to true only during the development period. --> <Compilation DEBUG = "true"/> <! -- <Authentication> zones can be used to set the Security Authentication mode used by ASP. NET to identify users who access the region. --> <Authentication mode = "Windows"/> <! -- <Customerrors> the region can be used to set the action to be performed when the bank fails to handle the operation within the required period. In practice, it allows developers to set the HTML webpage to be displayed to replace the hacker heap tracing. <Customerrors mode = "remoteonly" defaultredirect = "genericerrorpage.htm"> <error statuscode = "403" Redirect = "noaccess.htm"/> <error statuscode = "404" Redirect = "deny "/> </customerrors> --> </system. web> </configuration>
