Basic 6.0, you can store objects of any type with a collection class.
Collection of Visual Basic 6.0
Visual Basic 6.0 does allow you to store everything in a collection. However, the collection class has several limitations. We use an example to illustrate how to store this employee class in the collection:

Public FirstName as String

However, if that isn ' t possible, there is another way:column-level permissions. They is a little harder t

is simple:1. Search for websites with query strings (for example, query URLs with "id =" in the URL)2. Send a request to these websites that are determined to be dynamic, change the id = Statement and put an extra single quotation mark to try to cancel the SQL statement (for example, such as ID = 6 ')3. Analyze the returned responses and search for words such as "SQL" and "query". This often indicates that the application returns a detailed error message (which is also very bad)4. Check whether

1) Application Scenario: When data objects are modified, data may be disordered due to the order of changes. This can be avoided by using unchanged objects, you can also choose not to use the highly-available Synchronizing Method. The data held by an instance of the data model class remains unchanged throughout the lifecycle, and this class will be thread-safe.
2) design method:
A) All instance variables must be set in the constructor, because
to record these events and triggers. in this way, when a change occurs, the values can be automatically updated.
User-defined data types
User-defined data types allow you to extend the basic data types (such as varchar) of SQL Server by using descriptive names and formats customized for specific purposes ). For example, the following statement implements a birthday user-defined data type, which allows NULL and uses the datetime basic data class.
Type:
EXEC sp_addtype birthday, datetime, 'null
,*,unit= "meters"): ...If you use * as the first argument , then no positional arguments are allowed and the keyword argument is used when calling the function: Def print_set (*,paper= "letter", Copies=1,color=false): .... You can call Print_set () without using any parameters, or you can change some or all of the default values. However, if you use positional parameters, you will produce typeerror exceptions, such as Print_set ("A4").2. To split the mappings, you can use theMap Split Operator (
cipher) with a 128-bit key. This 128-bit key is derived from the password from the message digest. Encrypted passwords are independent of DB2 authentication and are used only for encryption and decryption of data.
Here you can provide an optional parameter passwordhint, which is a string that can help the user to remember the passwordorphrase used to encrypt the data. (For example, you can use ' George ' as a reminder to remember ' Washington '.) )
