在VB.net中，每个事件都对应有两个参数：sender 和 e 。提取 sender 参数信息就可以获取控件名称。如果不理解其中机制，你直接 msgbox(sender) 将其输出，就能查看其中玄机。
获取控件名称代码：CType(sender, Control).Name。
获取画面这个很容易
分析画面这个很难
模拟鼠标键盘操作这个也很容易
VB.net能写
难点:分析画面的代码!这个是你的辅助软件能否做出来的核心技术点
通过窗体的MouseDown事件的e.X和e.Y属性获取。通过e.Location属性获取Point类型的坐标。
下面的代码示例使用 Location 属性跟踪鼠标左键单击，并绘制一系列直线段作为对用户输入的响应。如果隐藏窗体然后重新显示它，此示例不保留已绘制的线段，该代码为简单起见而被省略了。
Dim FirstPoint As Point
Dim HaveFirstPoint As Boolean = False
Sub Form1_MouseDownDrawing(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseDown
If HaveFirstPoint Then
Dim g As Graphics = Me.CreateGraphics()
g.DrawLine(Pens.Black, FirstPoint, e.Location)
HaveFirstPoint = False
Else
FirstPoint = e.Location
HaveFirstPoint = True
End If
End Sub

Private Declare Function ScreenToClient Lib "user32.dll" (ByVal hwnd As Int32, ByRef lpPoint As POINTAPI) As Int32 '窗口坐标声明
Private Structure POINTAPI '声明坐标变量
Public x As Int32 '声明坐标变量为32位

End Structure

Dim P As POINTAPI '声明坐标变量
Dim xx, yy '声明转换要用到的变量
GetCursorPos(P) '获取鼠标在屏幕中的位置
ScreenToClient(Me.Handle.ToInt32, P) '转换为本窗体的坐标
xx = P.x.ToString '把X转换成能显示到文本框的字符串格式
yy = P.y.ToString '把Y转换成能显示到文本框的字符串格式
TextBox1.Text = xx + "和" + yy '文本框的内容为X坐标和Y坐标

控件中keyup属性记录键盘操作
比如：
Private Sub from1_KeyUp(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles MyBase.KeyUp
if e.keycode = keys.Enter then
lable1.text =Cursor.Position.X
lable2.text = Cursor.Position.Y
end if
end sub
