Skills 　　previous section: Flash 8 new features use skills Combat (2): Add Filter Part Three: Flash 8 blending mode New blending mode is added to the Flash8, allowing us to handle blending patterns between objects as we do in Photoshop. About the mixed mode, I believe that familiar with Photoshop friends must know very well, today let us see what Flash8 bring us what kind of blending mode.

Admindb.changeuserpassword ("username", "xxx")7. View user InformationDb.runcommand ({usersinfo: "UserName"})8. Change Password and user informationDb.runcommand ( { updateUser: "username", pwd: "xxx", customdata:{title: "xxx"} )Note:1. and user management related operations are basically to run under the Admin database, to use the admin first;2. If under a single database, it can only operate on the permissions of the current database;3.

); } }The implementation of a YYYY-MM-DD format conversion class, you can see just initialize isodatetimeconverter when the date format is YYYY-MM-DD, the following look at the effect[Jsonconverter (typeof (Chinadatetimeconverter))]public DateTime Birthday {get; set;}Different conversion classes can be implemented according to your needsSix. Custom serialized field names the attribute name defined in the entity may not be the name you want, but you cannot change the entity definition,

(function (){VaR combo = new Ext. Form. ComboBox ({Store: Emptytext: 'select a province ....',Applyto: 'combo'});}); // Aspx foreground HTML code We can use Variables and methods? (Variable calls are described above)6. How does JS and HTML call C # background variables and methods?I will not talk about this topic much, but I will explain it on the Internet.1. JS calls C # background variables. Refer to the above. Note that if you want to obtain the

role for the new user; In the Roles field, you can specify built-in roles and user-defined roles. Roles in role can be selected: Built-in Roles (built-in role): 1. Database user role: Read, readWrite; 2. Database management roles: DbAdmin, Dbowner, Useradmin; 3. Cluster Management role: Clusteradmin, Clustermanager, Clustermonitor, Hostmanager; 4. Backup Restore role: backups, restore; 5. All database roles: Readanydatabase, Readw

C #4.0 new features (3): Variable Variance (inverter and covariant ), To sum up one sentence: the covariant allows a coarse-grained interface (or delegate) to receive a more specific interface (or delegate) as a parameter (or return value); the inverter allows an interface (or delegate) the parameter type (or return value) of is more specific, that is, the parameter type is stronger and clearer. Usually, th

development,Networkworms are getting popular, and VBS scripting worms are more prominent, not only large, but also powerful. Since the use of scripting virus is relatively simple, in addition to continue to popular current VBS script virus, will gradually appear more other script-like virus, such as Php,js,perl virus. But scripts are not the best tool for real virus technology enthusiasts to write viruses, and scripting viruses are easier and relatively easy to prevent. The author believes that

projection accuracy is high, the deformation is small, and the computation is simple (the coordinates of each projection are the same, as long as the data of one belt is calculated, other bands can be applied ), therefore, it can be used in large-scale topographic maps to meet various military needs and perform precise measurement and calculation on the charts. (2) Gaussian-kerluge projection band The earth's elliptical sphere is divided into several projection bands by a certain longitude diff

applied ), therefore, it can be used in large-scale topographic maps to meet various military needs and perform precise measurement and calculation on maps. (2) Gaussian-kerluge projection band The earth's elliptical sphere is divided into several projection bands by a certain longitude difference, which is the most effective method for limiting length deformation in Gaussian projection. When dividing the band, you must control the length deformation so that it is not greater than the ing error

, through its subclasses to implement this time requires that the subclass must be able to replace the parent class wherever it appears, the advantage is that The new subclass of the parent class interface is extended according to the new requirements without affecting the current client's use! dependency Inversion principle (DIP)In traditional structured programming, the topmost modules are usually dependent on the following sub-modules, also known as high-level dependence on the lower levels!S

FilesMatch and access control directory features are similar, except that FilesMatch Controls access control for smaller-scale layers (files). To configure the access control FilesMatch method: Vim/usr/local/apache2.4/conf/extra/httpd-vhosts.conf The configuration file adds the following:Order Deny,allowDeny from allAllow from 127.0.0.1 Reload the configuration file:/usr/local/apache2.4/bin/apachectl-t/usr/local/apache2.4/bin/apachect

The previous section said 16-bit Timer 1, this section is about 8-bit timer 3 and timer 4!1. OverviewTimer 3 and Timer 4 are two 8-bit timers (8-bit timers). Each timer has a dual independent capture/compare channels (separate capture/compare channel), each using one I/O pin per channel.　　Features:· Capture/compare Channels· Set, clear or toggle output Compare· C
