：打开快捷方式以及程序
SHELL "路径"

2：打开硬盘或文件
Shell "explorer F:", vbNormalFocus

3：打开“我的电脑”“资源管理器”……

Shell "EXPLORER.EXE /n, /e, ::{20D04FE0-3AEA-1069-A2D8-08002B30309D}"
4：打开网页
SHELL " www.hao123"



---------------------------------------------------------------


参数说明
/n表示以“我的电脑”方式打开一个新的窗口，通常打开的是Windows安装分区的根目录。

/e表示以“资源管理器”方式打开一个新的窗口，通常打开的也是Windows安装分区的根目录。

/root,[path]表示打开指定的文件夹，/root表示只显示指定文件夹下面的文件(夹)，不显示其他磁盘分区和文件夹；[path]表示指定的路径。

如果不加/root参数，而只用[path]参数，则可以显示其他磁盘分区和文件夹中的内容。另外，[path]还可以指定网络共享文件夹。

/select,[path filename]表示打开指定的文件夹并且选中指定的文件，[path filename]表示指定的路径和文件名。


如果不加/select参数，则系统会用相应的关联程序打开该文件。如果[path filename]不跟文件名就会打开该文件夹的上级目录并选中该文件夹。

IF判断句详解，这是编程里面最基本的语句，我做一个小例子，如如果想让显示出来的是星号
在这里设
If Text1.Text = "463746790" Then 这里就是设置的默认密码
MsgBox "注册码正确！谢谢使用！", , "系统提示"这是登陆成功的提示
Unload Me
Else
这里是注册码不正确的时运行的命令，试一下，这是错误的效果；这是正确的效果
MsgBox "注册码错误。请发送邮件到samsungyjl@126", , "错误！"
Text1.Text = ""
Command3.Enabled = False
End If
End Sub

MsgBox "这里是消息的内容", , "这里是消息的标题"看到了吗？

MsgBox这个就是消息提示框，我讲一下用法
我们给退出做一个消息框 这就是效果
