sendmessage函数问题

pdp320921

Local Const $VK_RBUTTON =0x02 
        Local Const $WM_KEYDOWN = 0x0100
        Local Const $WM_KEYUP =0x0101 
               $hwnd = WinGetHandle('')
        DllCall("User32.dll","Int" ,"SendMessage","HWnd",$hwnd,"Int", $VK_RBUTTON,"Int",$WM_KEYDOWN,"int","0")
        DllCall("User32.dll","Int" ,"SendMessage","HWnd",$hwnd,"Int", $VK_RBUTTON,"Int",$WM_KEYUP,"int","1")

请教大侠们上述代码为何不能实现mouseclick("right")的效果？

一个记事本例子

#include <winapi.au3>
Const $WM_RBUTTONDOWN = 0x204
Const $WM_RBUTTONUP = 0x205

Run("notepad.exe")
$Hwnd = WinWaitActive("[class:Notepad]")
$Hanld = ControlGetHandle($Hwnd,"","Edit1")
$Lparm = _WinAPI_MakeLong(100,105) ;x=100,y=105
;右键按下，弹起，弹出右键菜单
_SendMessage($Hanld,$WM_RBUTTONDOWN,0,$Lparm)
_SendMessage($Hanld,$WM_RBUTTONUP,0,$Lparm)

$Hwnd = WinWaitActive("[class:Notepad]")

$Lparm = _WinAPI_MakeLong(100,105) ;x=100,y=105

   DllCall("User32.dll","Int" ,"SendMessage","HWnd",$Hanld,"Int", $WM_RBUTTONDOWN,"Int",$WM_KEYDOWN,"int",$Lparm)
        DllCall("User32.dll","Int" ,"SendMessage","HWnd",$Hanld,"Int", $WM_RBUTTONUP,"Int",$WM_KEYUP,"int",$Lparm)

把$VK_RBUTTON换成$WM_RBUTTONDOWN,添加坐标,试了是可以达到了

不知道$VK_RBUTTON和$WM_RBUTTONDOWN区别在哪？
