12、运行时是否有效对象.属性属性值对象中属性可以在设计界面时通过属性窗中设置，也可以在运行时通过程序代码设置,方法如下例：给文本框“Txt123”的“Text”属性赋值为字符串“20”，代码如下Txt123.text=”20”变量对象.属性如果要获取对象的状态或特性，这时就要读取对象的属性值，方法如下例：读取文本框“txt123”的“Text”属性的代码如下a=txt123.text 2 方法对象.方法参数名表例：form.print”欢迎使用”该语句使用 print方法在 form1 窗体中显示字符串“欢迎使用”3 事件及事件驱动事件是对象对外部操作的响应，如在程序执行时，单击命令按钮会产生一个
13、 Click 事件。如需要命令按钮响应Click事件，就把完成 Click事件功能的代码写到Click 事件的事件过程中，与事件一一对应。精品资料-欢迎下载-欢迎下载 名师归纳-第 3 页，共 33 页 -文档编码:CU5V9S2R2O8 HB1H9V7W10I8 ZV8P6P8K6S1文档编码:CU5V9S2R2O8 HB1H9V7W10I8 ZV8P6P8K6S1文档编码:CU5V9S2R2O8 HB1H9V7W10I8 ZV8P6P8K6S1文档编码:CU5V9S2R2O8 HB1H9V7W10I8 ZV8P6P8K6S1文档编码:CU5V9S2R2O8 HB1H9V7W10I8 ZV8

29、数值如1、0、-10、+35 等都是合法的整数实型常量：即实数，指带小数点的数值。实型常量又分为定点数和浮点数两种。例：定点数：3.14159 和-6.8，1.99 浮点数：2E6、1E5、88E 例：1.2345103 可表示为 1.2345E3，字母 E表示底数 10 浮点数就是数学上的科学计数法。字符串常量：被一对双引号括起来的若干个合法的字符称为字符串常量。例如：”China”、”Visual Basic”、”18”、”3.1415”等，双引号中字符，不包括双引号本身。符号常量：如果多次用到同一个常量，则可用一个有意义的名字表示这个常量。二、变量：在程序执行过程中，其值可以改变的量称为
30、变量变量命名注意要点：1、必须以字母开头,不能以数字或其他字符开头。2、只能由字母、汉字、数字学或下划线组成，不能含有小数点、空格等字符。3、最长不超过 255个字符4、不能以 VB保留字作变量名，如语句定义符、函数名等。5、VB不区分变量名中字母大小写。如HELLO 和Hello 是同一个变量。数据及运算（1）常用数据类型：(整型)Integer、（长整型）Long、（单精度型）Single、（双精度型）Double、（字符串型）String、（布尔型）Boolean、（日期型）Date 其中(整型)Integer、（长整型）Long、（单精度型）Single、（双精度型）精品资料-欢迎下载
