谢谢!你是怎么查到的?授渔吧,谢谢!

Protected Overrides Sub WndProc(ByRef m As System.Windows.Forms.Message)
If (m.Msg = &H112) Then
If (m.WParam = &HF020) Then
Console.WriteLine( 最小化按钮点击了 )
ElseIf (m.WParam = &HF030) Then
Console.WriteLine( 最大化按钮点击了 )
ElseIf (m.WParam = &HF060) Then
Console.WriteLine( 关闭按钮点击了 )
End If

End If
MyBase.WndProc(m)

这是定义好的

教教我怎么查吧,我想知道窗体从最小化到窗体重现在屏幕上的消息是什么?
__________________________________________________________________________
最小化的消息是SC_MINIMIZE
__________________________________________________________________________

用 SC_MINIMIZE 要 imports 什么?
__________________________________________________________________________
不需要imports , 你需要自己定义一个常量

Private Const SC_MINIMIZE = &HF020&

If (m.WParam = SC_MINIMIZE) Then
Console.WriteLine( 最小化按钮点击了 )

最小化的消息是SC_MINIMIZE

===================================================

会变量未定义 ,要 import 什么?


__________________________________________________________________________
那在 VC 中 有 SC_MINIMIZE 这常量定义 。vb中不能引用吗?
__________________________________________________________________________
你参考下面的代码,常用常数:
Protected Overrides Sub WndProc(ByRef m As System.Windows.Forms.Message)
Dim SC_ARRANGE As Integer = &HF110
Dim SC_CLOSE As Integer = &HF060
Dim SC_HOTKEY As Integer = &HF150
Dim SC_HSCROLL As Integer = &HF080
Dim SC_KEYMENU As Integer = &HF100
Dim SC_MAXIMIZE As Integer = &HF030
Dim SC_MINIMIZE As Integer = &HF020
Dim SC_MOUSEMENU As Integer = &HF090
Dim SC_MOVE As Integer = &HF010
Dim SC_NEXTWINDOW As Integer = &HF040
Dim SC_PREVWINDOW As Integer = &HF050
Dim SC_RESTORE As Integer = &HF120
Dim SC_SCREENSAVE As Integer = &HF140
Dim SC_SIZE As Integer = &HF000
Dim SC_TASKLIST As Integer = &HF130
Dim SC_VSCROLL As Integer = &HF070

If (m.Msg = &H112) Then
If (m.WParam = SC_MINIMIZE) Then
Console.Write( 最小化按钮点击了 )
ElseIf (m.WParam = SC_MAXIMIZE) Then
Console.Write( 最大化按钮点击了 )
ElseIf (m.WParam = SC_CLOSE) Then
Console.Write( 关闭按钮点击了 )
ElseIf (m.WParam = SC_RESTORE) Then
Console.Write( 还原按钮点击了 )
End If
Console.WriteLine(m)
End If
MyBase.WndProc(m)
End Sub
__________________________________________________________________________
但你们用
Dim SC_CLOSE As Integer = &HF060
这样常数,操作系统变了怎么办?
__________________________________________________________________________
一般是不会变啦,这是微软定义好的

就算变啦,只要该这个常数就可以拉
__________________________________________________________________________
常数
是不会变的,不会变的才叫常数:)
