è Dynamic and Static Menu (omitted)
2.5.5. Login
Mainly for user login, registration, retrieval / change password, etc.
2.5.6. WebParts
1) Introduction: Compared with SharePoint, design purposes allows users to define pages. You can also customize Design Web Part
2) Application
è Use Web Part to have only one WebPartManager control
è Web Part must be placed in WebPartzone
è Special web part uses special Web Part Zone
è You can realize the connnection2.5.7 of Web Parts. Crystal Reports (omitted)
2.5.8. HTML ()
2.6. ASP.NET Security
2.6.1. MemberShip
Membership Provides Secure Credential Storage With Simple, Easy-To-Use Apis. BCHOA is easier to implement, it is easier for system extensions.
The Membership Provider Model
We can easily implement MEMBERSHIP Provider. So MEMBERSHIP can support:
è SQL Server
è Access (MDB)
è ad (NOT Available with the beta release of asp.net 2.0.)
2.6.2. Web Site Administration Tool
1) Web Manager
http://localhost/aspnet_Webadmin/2_0_40607/default.aspx? ApplicationPhysicalPath = [Site Folder Path] & ApplicationURL = [Application URL]
2) Security configuration: Take the User to manage and assign the role or user directory access.
3) Profile configuration: (omitted)
4) Counter Configuration: ()
The Membership Configuration
TYPE = "System.Web.Security.accessmembershipProvider, System.Web, Version = 2.0.3600.0, Culture = neutral, publickeyToken = B 03F 5F 7f 11D 50A 3A " ConnectionstringName = "accessfilename" EnablepasswordRetrieval = "false" EnablepasswordReset = "true" RequiresquestInSwer = "false" ApplicationName = "/" Requiresuniqueemail = "false" PasswordFormat = "HASHED" Description = "Stores and Retrieves Membership Data from The Local Microsoft Access Database File" /> ... * ConnectionstringName: The name of the database connection string (database connection string defined in web.config). * PasswordFormat: include encrypted and clear. The default value is hashed. * Use the Web Site Administration Tool to automatically generate configure.2.2.2.2.2.2.2.2.2.2.2.2.7. The New Browser and MOBILE Device Controls 2.7.1. Brower definitions Due to operational environment, such as: Since the ASP.NET output is not necessarily IE browsing, for example, you want to browse on Mobile Device. You don't need to make a UI that support Mobile Device on ASP.NET 2.0, you can configure it Configuration to define the browsing output. 2.7.2. Mobile Device Controls 1) Standard Form- and page-based controls, Such as the bullet list and fileupload controls 2) Rich Controls, Such as The DynamicImage Control and The Wizard Control 3) Login and Authentication Controls, Used In Conjunction with Access Control Features 4) Navigation Controls, Such as The Tree View and Site Map Controls, And Counters 5) Data Access And Display Controls Designed to Display Relational Data, XML Data, And Data Held in Other Formats 6) Mobile Device Controls, Such as The Phone Call and PAgination Controls 2.8. Cache and Application Configuration 2.8.1. Cache Configuration 1) SQLCache Use the Command Line tool ASPNET_REGSQLCACHE.EXE to configure SQLCache (specific use parameters can view HELP) 2) ASP.NET CACHE ASP.NET stores some buffer data in the SQL ASPNET_SQLCACHETABLESFORCHANGENOTIFICATION table. Set SQL Server Cache Dependency in Web.config Connectionstring = "Server = localhost; Database = northwind; UID = sa; pwd = 00password "/> Connectionstringname = "northwind" PollTime = "500" /> 3) Page Output-Cache In addition to Web.config, you can set the sqldependency property in the <% @ outputcache%> page of the page, such as: <% @ outputcache duration = "9999" Varybyparam = "none" Sqldependency = "northwind: products"%> 4) SQLCachedependency Class and Cachedpendency Class Sqlcachedependency is a new Class of ASP.NET 2.0, under System.Web.Caching Namespace, is used to build Cache Dependencies On Microsoft SQL Server 7, 2000, and 2005 Databases. Cachedependency (, Introducted In ASP.NET 1.0) 2.8.2. Application Configuration Web.config also has considerable changes with Machine.config. The new configuration part is mainly reflected in: è Anonymous Identification è Code Dom è connect strings è data è caching è _EXPRESSION Builders è hosting è image generation è http cookies è MemberShip è site maps è Site Counters è Personalization Profile è protocol bindings è Role Manager è Mail Servers è url mappings è Web Parts è Web Site Administration Tool è protected data è health monitoring 3. Summary è function performance implementation ASP.NET 2.0 has a concept of software engineering management: developers focus on system business logic, rather than UI; MEMBERSHIP is designed in terms of verification, more convenient for Form verification authorization development (although compared to the Authorization and Profile Application Block, the implementation of business logic is relatively simple, but still very practical, you can apply to our numerous general system ); To meet the future Mobile Device era trend, ASP.NET 2.0 has supported Mobile Device more than the previous version and other web programming; To SQL, it is more proposed to effectively improve SQL's cache performance. è software program design A large number of powerful practical controls can solve all the functionality and performance issues of all UIs, etc., which will greatly reduce the development cost of UI layers. Remove the concept of Project's Project before the ASP.NET 2.0, directly publish a local directory; The combination of Web Part is more user-friendly; Dynamic compilation mode makes the developer do not need to recompile and restart debugging. ASP.NET 2.0 is an exciting product that let us look forward to its official release.
