'--以下为VB模拟鼠标的说明及例子
'-------------------------------------------'
' 模拟鼠标的左键单击和右键单击'
'-------------------------------------------'
'程序说明：'
'本例采用API函数实现模拟的鼠标事件，程序运行后会'
'产生十分有趣的效果。也来试一试。'
'本例中只使用了相对鼠标坐标，我们也可以使用绝对'
'鼠标坐标来试一试。'

' 进行相对运动的时候，由SystemParametersInfo函数规定的系统鼠标轨迹速度会应用于鼠标运行的速度'

' dx和dy指定鼠标坐标系统中的一个绝对位置。在鼠标坐标系统中，屏幕在水平和垂直方向上均匀分割成65535×65535个单元 -'
' MOUSEEVENTF_MOVE 移动鼠标'
' MOUSEEVENTF_LEFTDOWN 模拟鼠标左键按下'
' MOUSEEVENTF_LEFTUP 模拟鼠标左键抬起'
' MOUSEE

VENTF_RIGHTDOWN 模拟鼠标右键按下'
' MOUSEEVENTF_RIGHTUP 模拟鼠标右键抬起'
' MOUSEEVENTF_MIDDLEDOWN 模拟鼠标中键按下'
' MOUSEEVENTF_MIDDLEUP 模拟鼠标中键抬起'
' dx ------------- Long，根据是否指定了MOUSEEVENTF_ABSOLUTE标志，指定水平方向的绝对位置或相对运动'

' dy ------------- Long，根据是否指定了MOUSEEVENTF_ABSOLUTE标志，指定垂直方向的绝对位置或相对运动'

' cButtons ------- Long，未使用'

' dwExtraInfo ---- Long，通常未用的一个值。用GetMessageExtraInfo函数可取得这个值。可用的值取决于特定的驱动程序'
