VB中from的load事件

这个事件是用来干什么的
一般怎么用

Answer 1

From的Load事件主要用于窗体加载时对一些变量或窗体上控件属性的初始化设置.例:
Private Sub Form_Load()
step1 = 1: Caption = "欢迎使用VB"
Timer1.Interval = 0
End Sub

又例:
Option Explicit
Dim fnt As Long
Public Function xp(colvb As Variant, xx As Variant, yy As Variant, fnt As Variant, txt As Variant)
Picture1.ForeColor = colvb
Picture1.CurrentX = xx
Picture1.CurrentY = yy
Picture1.FontSize = fnt
Picture1.Print txt
End Function

Private Sub Form_Load()
xx = 100: yy = 100
colvb = vbRed
txt = "123"
fnt = 24
wp = xp(colvb, xx, yy, fnt, txt)
yy = 200
xx = 2000
colvb = vbGreen
txt = "POY"
fnt = 48
wp = xp(colvb, xx, yy, fnt, txt)
End Sub

Answer 2

一个窗体加载到内存的时候触发,也就是说一个程序运行时首先会执行一下load里的代码.

load里一般都放一些数据的初始化程序.

上面的同志已经写的很详细啦。不知道你看懂没有？打个比喻：就象刚一进别人家的门的时候，别人给你打声招呼！
