使用spy ++跟踪传递到菜单栏的所有事件，然后尝试重新发送程序中的消息。

Answer 2

After long research and with help of dvasanth ,i find the salution

1.Yon need to find WM_LBUTTONUP/DOWN NOT WM_SETCURSOR like in img,than open the properties and find wParam and lParam

2.Change format 011C16A8 just by adding 0x+lParam/wParam

Ex: 011C16A8 = 0x011C16A8

EX: 00000001= 0x01

EX: 00000012=0x12

I think i get an idea....

In my case i find in properties :

WM_LBUTTONUP

lParam=00000001
wParam=000C0348

WM_LBUTTONDOWN

lParam=00000000
wParam=000C0348

sow after edit they look like this:

WM_LBUTTONUP

lParam=0x01
wParam=0x000C0348

WM_LBUTTONDOWN

 lParam=0x00
 wParam=0x000C0348

3.Just insert this to your code.

My code that worked:

intRes1 = PostMessage(currChild, WM_LBUTTONDOWN, 0x01, 0x000C0348);
System.Threading.Thread.Sleep(100);
intRes1 = PostMessage(currChild, WM_LBUTTONUP, 0x00, 0x000C0348);
