vb点虐 隐藏光标 vbs 隐藏窗口

VB.NET按下一个按钮如何弹出第三个窗口，隐藏第一个和第二个

首先要添加两个窗体，假设第一个窗体名为Form1，第二个窗体名为Form2。在Form1窗体中添加个按钮Command1。按钮单击事件的代码为：

Private Sub Command1_Click()

Form2.Show '用show方法加载并且显示名为Form2的窗体

End Sub

show 方法后面省略了两个参数即Form2.Show 0或Form2.Show 1此参数可缺省。可自行运行验证

VB点虐 里面的工具栏怎么能自动隐藏？

工具栏 一般都有自动隐藏，在工具栏的左或者右上方 有个图标可以选择隐藏的，我用的VS2010 反正在那里有设置的！

VB.NET改变鼠标位置和让鼠标消失

几乎找不到真正VB.NET的api，都是自己将VB的api改成VB.NET的api，我的理解是声明中对应输入是H的地方保留Long，其他的Long改成Integer，既然VB.NET连MSDN都找不到较全的api说明，不保证api的用法在VB.NET其他版本中适用。

给你个好玩的例子，包括鼠标的隐藏（Ctrl_↓）、显示（Ctrl_↑），移动、点击

在Form1上放上2个TextBox，其中TextBox1.Multiline = True，并且面积大些，2个Button，运行后在TextBox1中点击一下会记录位置，移开鼠标，点击移动或点击Button，可模拟在TextBox1中的点击

Public Class Form1

Public My_MousePosition As Point

'模拟鼠标移动、点击

Declare Sub mouse_event Lib "user32" (ByVal dwFlags As Long, ByVal dx As Integer, ByVal dy As Integer, ByVal cButtons As Long, ByVal dwExtraInfo As Long)

'定义光标的位置

Declare Function SetCursorPos Lib "user32" Alias "SetCursorPos" (ByVal x As Integer, ByVal y As Integer) As Integer

'鼠标的隐藏

Declare Function ShowCursor Lib "user32" Alias "ShowCursor" (ByVal bShow As Integer) As Integer

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

TextBox1.Multiline = True

Button1.Text = "点击"

Button2.Text = "移动"

Me.KeyPreview = True

End Sub

Private Sub Form1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown

If e.Control And e.KeyCode = Keys.Down Then ShowCursor(0)

If e.Control And e.KeyCode = Keys.Up Then ShowCursor(1)

End Sub

Private Sub Form1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseMove

TextBox2.Text = MousePosition.X " " MousePosition.Y

End Sub

Private Sub TextBox1_MouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles TextBox1.MouseClick

My_MousePosition = MousePosition

TextBox1.Text = My_MousePosition.X " " My_MousePosition.Y vbCrLf

End Sub

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

SetCursorPos(My_MousePosition.X, My_MousePosition.Y)

mouse_event(H2, 0, 0, 0, 0)

mouse_event(H4, 0, 0, 0, 0)

End Sub

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click

SetCursorPos(My_MousePosition.X, My_MousePosition.Y)

End Sub

End Class

其中

mouse_event Lib "user32" (ByVal dwFlags As Long

的dwFlags的代码是

Const MOUSEEVENTF_LEFTDOWN = H2

Const MOUSEEVENTF_LEFTUP = H4

Const MOUSEEVENTF_MIDDLEDOWN = H20

Const MOUSEEVENTF_MIDDLEUP = H40

Const MOUSEEVENTF_MOVE = H1

Const MOUSEEVENTF_ABSOLUTE = H8000

Const MOUSEEVENTF_RIGHTDOWN = H8

Const MOUSEEVENTF_RIGHTUP = H10
