Here''s the code;

Public Class Form1
    Public Declare Auto Function SetCursorPos Lib "User32.dll" (ByVal X As Integer, ByVal Y As Integer) As Integer
    Public Declare Auto Function GetCursorPos Lib "User32.dll" (ByRef lpPoint As Point) As Integer

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

    Private Const MOUSEEVENTF_ABSOLUTE = &H8000 ' absolute move
    Private Const MOUSEEVENTF_LEFTDOWN = &H2 ' left button down
    Private Const MOUSEEVENTF_LEFTUP = &H4 ' left button up
    Private Const MOUSEEVENTF_MOVE = &H1 ' mouse move
    Private Const MOUSEEVENTF_MIDDLEDOWN = &H20

    Private Const MOUSEEVENTF_RIGHTDOWN = &H8
    Private Const MOUSEEVENTF_RIGHTUP = &H10
    Private Const MOUSEEVENTF_WHEEL = &H20A

    Private Sub mouseCommands

        ' Wheel Rotation Forward 
        ' ??????????

        ' Wheel Rotation Backward
        ' ??????????

        ' Left Mouse-DoubleClick
        mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0) ' Button Press
        mouse_event(MOUSEEVENTF_LEFTUP, 0, 0, 0, 0) ' Button Release
        mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0) ' Button Press
        mouse_event(MOUSEEVENTF_LEFTUP, 0, 0, 0, 0) ' Button Release

        ' Left Mouseclick
        mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0)
        mouse_event(MOUSEEVENTF_LEFTUP, 0, 0, 0, 0)

        ' Right Mouseclick
        mouse_event(MOUSEEVENTF_RIGHTDOWN, 0, 0, 0, 0)
        mouse_event(MOUSEEVENTF_RIGHTUP, 0, 0, 0, 0)

        ' Middle Click
        mouse_event(MOUSEEVENTF_MIDDLEDOWN, 0, 0, 0, 0)
        mouse_event(MOUSEEVENTF_MIDDLEUP, 0, 0, 0, 0)

        ' Set Mouse Cursor to a specific position
        SetCursorPos(300, 400)

        ' Drag and drop
        SetCursorPos(300, 400) ' Where your desired file is located at(screenheight, screenwidth)
        mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0)
        SetCursorPos(500, 500) ' Where to release file, respectively the button
        mouse_event(MOUSEEVENTF_LEFTUP, 0, 0, 0, 0)
    End Sub

推荐答案

仅一个建议:mouse_event被更新的功能SendInput取代: http://msdn.microsoft.com/zh-我们/library/windows/desktop/ms646273%28v=vs.85%29.aspx [ http://www.pinvoke.net/default.aspx/user32.sendinput [ ^ ].

Just one advice: mouse_event was superseded with newer function SendInput: http://msdn.microsoft.com/en-us/library/windows/desktop/ms646310%28v=vs.85%29.aspx[^].

Use it.

If works; wheel events can be used, which is described here:

The P/Invoke version is already written for you, courtesy of PInvoke.NET:
