SendMessage发送鼠标单击事件

我想向一个网页的某一位置发送一个鼠标单击信息，就是想用程序来按网页，我找过很多资料，都只能按到按钮，但我想是按到一个位置（位置上可能是图片，文字，或超级链接），有什么方法？
这段是我写的，可是不行：
g_WindowHwnd = FindWindow(vbNullString, "XXX - Windows Internet Explorer")

hWnd1 = g_WindowHwnd

Dim x As Integer, y As Integer, res As Long

x = Int(Text1.Text)
y = Int(Text2.Text)

Dim r1, r2 As Long

res = (y * &H10000) + x
r1 = SendMessage(hWnd1, WM_LBUTTONDOWN, MK_LBUTTON, ByVal res)
r2 = SendMessage(hWnd1, WM_LBUTTONUP, MK_LBUTTON, ByVal res)
（句柄没问题）

最后100分，谢谢.

Answer 1

One Possible Answer:

Change SendMessage into mouse_event
{
Private Declare Sub mouse_event Lib "user32" (ByVal dwFlags As Long, ByVal dx As Long, ByVal dy As Long, ByVal cButtons As Long, ByVal dwExtraInfo As Long)

Call mouse_event(&H2, 0, 0, 0, 0)
Call mouse_event(&H4, 0, 0, 0, 0)
}

Answer 2

c#的代码:

[DllImport("user32", EntryPoint = "SetCursorPos")]
public extern static void SetCursorPos(int x, int y);

[DllImport("user32", EntryPoint = "mouse_event")]
public extern static void Mouse_Event(int dwFlags, int dx, int dy, int dwData, IntPtr dwExtraInfo);

public enum MouseEventFlags
{
LeftDown = 0x0002,
LeftUp = 0x0004,
Absolute = 0x8000
}
//int x ,y为横坐标与纵坐标
public void MouseMoveClick(int x, int y)
{
SetCursorPos(x, y);
Win32API.Mouse_Event((int)(MouseEventFlags.LeftDown | MouseEventFlags.Absolute),0,0,0,IntPtr.Zero);
Win32API.Mouse_Event((int)(MouseEventFlags.LeftUp | MouseEventFlags.Absolute), 0, 0,0,IntPtr.Zero);

}
