End Sub2、 form1按钮点击事件:
form2.show
form1.hide 3、
启动VB程序,在窗体上放置6个命令按钮,三个标签,一个公用对话框、一个进度条、一个状态栏和一个计时器,窗本的布置请参考附图按钮"Open MP3 File"是用来打开对话框选择MP3文件,其他5个按钮分别为Play(播放)、Pause(暂停)、Stopplay(停止播放)、Back(向后跳跃)、Prew(向前跳跃)。Label1用来表示歌曲当前时间;label2放在时度条的最左边,Caption属性为"00:00";lable3放在时度条的右边,用来表示歌曲总长。下面就可以编写代码了。首先在窗体的"通用声明"部分声明函数
Private Declare Function mciSendString Lib "winmm.dll" Alias "mciSendStringA" (ByVal lpstrCommand As String, ByVal lpstrRetumString As String, ByVal uReturnLength As Long, ByVal hwndCallback As Long) As Long

下面就是各个对象的代码了:

罪犯是C吧。很好玩的游戏,用脑子想的话就很快的出谁是答案。用编程的话就会墨迹点,因为要表现他们的 *** 作。
VBS或者VB都可以
Dim P(4),X(4)

P(1)= "B":X(1)=0'X(1)代表B被怀疑的次数
P(2)= "C":X(2)=0'X(2)代表C被怀疑的次数
P(3)= "D":X(3)=0'X(3)代表D被怀疑的次数

Select Case P(i)'假设其中一人说了假话,把其余人的推理都验证一遍,在推理过程中被怀疑者加1

VB脚本就是VBScript,是微软公司推出的网页脚本语言,用于编写网页,VBScript不能独立运行,必须嵌在网页之中,通过浏览器来运行。而VB是微软公司推出的功能非常强大的编程工具,用于编写各类应用程序。
二者的关系是:VBScript是VB的子集。编网页时用的是VBScript。
