VB显示系统时间的代码是什么

VB显示系统时间的代码如下：text1.text="今天是" & Format$(Now,"Long Date") text2.text=Format$(Now,"dddd") text3.text=Format$(Now,"Long Time")Visual Basic是一种由 Microsoft 公司开发的结构化的、模块化的、面向对象的、包含协助开发环境的事件驱动为机制的可视化程序设计语言。

请帮我解释一个VB程序代码吧，很简单的代码！

me，就是“我”，在vb里面指当前窗体，这个可以省略，而且一般都省略。textwidth和texthight是函数而不是属性，他们的参数应该是字符串，返回值是在当前窗体的文字大小设定情况下这个字符串的宽度和高度，一般用来排版用。

vb编写程序判断两位整数m是否为守形数

一个n位数如果平方后末尾n位等于该数，则称其为守形数。因此，判断一个两位数m是否为守形数的方法如下：1. 将m的值平方，并将结果转换为字符串类型。2. 判断字符串的最后两个字符是否等于m本身的字符串表示。3. 如果相等，则说明m是守形数；否则不是。以下是VB语言的示例代码：```vbDim m As Integerm = 25Dim square As Integersquare = m * mDim strSquare As StringstrSquare = CStr(square)If Right(strSquare, 2) = CStr(m) Then MsgBox(m & "是守形数")Else MsgBox(m & "不是守形数")End If```在这个程序中，我们首先定义了一个整数变量m，代表需要判断的两位数。然后，我们将m的平方赋值给另一个整数变量square，并将其转换为字符串类型strSquare。接着，我们使用VB语言提供的Right函数取得字符串strSquare的最后两个字符，并将其与m的字符串表示进行比较。如果相等，则输出m是守形数的消息框；否则输出m不是守形数的消息框。注意，在实际应用中，应该对输入数据进行有效性检查，以确保输入的数值符合要求（例如必须为两位正整数）。

VB语言的各代码表示意思是什么

dim a as integerdim是定义的意思integer是整形这句话的意思就是"定义变量a为整形"具体的你看看书

如何用vb语言编写水仙花数的代码

这个是打印所有三位数的水仙花数的代码：Private Sub Command1_Click()For a = 1 To 9 For b = 0 To 9 For c = 0 To 9 If a * 100 + b * 10 + c = a ^ 3 + b ^ 3 + c ^ 3 Then print a * 100 + b * 10 + c End If Next Next NextEnd Sub

VB语言编程的格式及代码

        Visual Basic是它源自于BASIC编程语言。VB拥有图形用户界面（GUI）和快速应用程序开发（RAD）系统。

        VB编程有结构化的、模块化的、面向对象的、包含协助开发环境的事件驱动为机制的可视化程序设计语言。

        在 Visual Basic 中，可通过属性、方法和事件来说明和衡量一个对象的特征。
