End Subvb的窗口运行时位于最前端
在VB6.0里要先在最前面进行如下声明
Private Declare Function SetWindowPos Lib "user32" (ByVal hwnd As Long, ByVal hWndInsertAfter As Long, ByVal x As Long, ByVal y As Long, ByVal cx As Long, ByVal cy As Long, ByVal wFlags As Long) As Long
在过程中加入
SetWindowPos Me.hwnd, -1, 0, 0, 0, 0, 3就可以了，还原把 -1 改为 -2 。
如果是VB.net就容易了，直接在窗体属性中设置TopMost属性就行了
vb中日期显示格式
Print Format(Now(), "yyyy年m月d日 HH时MM分SS秒")VB函数if
Dim aa as String '定义一个字符变量
aa="123" '字符变量定义
If aa="123" Then '判断aa的值是否与字符"123"相同
Msgbox "aa的内容是123。"
Else
Msgbox "aa的内容不是123。"
End IfVB如何调用函数
private Function fn1() as string '函数fn1,返回字符串类型的值
'函数体
fn1 = "你好"
end Function
private Function fn2(n as boolean) as string '函数fn2
fn2 = iif(n,"真","假")
end function
调用时:
dim str as string
str = fn1 'str = "你好"
str = fn2(true) 'str = "真"VB编程显示星期几
Private Sub Command1_Click()
Dim i As Long
i = Weekday(Now)
Select Case i
Case 1
Label1.Caption = " 星期天"
Case 2
Label1.Caption = "星期一"
Case 3
Label1.Caption = "星期二"
Case 4
Label1.Caption = "星期三"
Case 5
Label1.Caption = "星期四"
Case 6
Label1.Caption = "星期五"
Case 7
Label1.Caption = "星期六"
End Select
End Subvb语言获得系统时间
Now:系统日期及时间
Date:系统日期
Time:系统时间
如text1.text=Now ‘显示系统日期及时间
text1.text=Date ‘显示系统日期
text1.text=Time ‘显示系统时间
用NOW()获得现在时间 data（）获得年月日 weekday（）获得星期
Option Explicit

VB中Integer（整型）和Long（长整型）有什么区别?
Integer 数据类型
Integer 变量存储为 16位（2 个字节）的数值形式，其范围为 -32,768 到 32,767 之间。Integer 的类型声明字符是百分比符号 (%)。
Long 数据类型
Long（长整型）变量存储为 32 位（4 个字节）有符号的数值形式，其范围从 -2,147,483,648 到 2,147,483,647。Long 的类型声明字符为和号 (&)。
