如何获得主菜单的处理程序 [英] How to get the handler of main menu

问题描述

我正在编写自动化测试，但是我对如何获取主菜单的处理程序感到困惑，虽然我觉得下面的代码是正确的，我无法得到正确的值。

I am writing automated test, but I get confused about how to get the handler of main menu, although I feel the following code is correct, I can not get the correct value.

[DllImport("user32.dll")] 
static extern IntPtr GetMenu(IntPtr hWnd);
[DllImport("user32.dll")] 
static extern IntPtr GetSubMenu(IntPtr hMenu, int nPos);
[DllImport("user32.dll")] 
static extern int GetMenuItemID(IntPtr hMenu, int nPos);

public void FormExitApp(int subMenu, int exitItem)
{
    IntPtr pMenu = GetMenu(this.ptrToWindow);  // pMenu = 0, ptrToWindow is a correct value.
    IntPtr pSubMenu = GetSubMenu(pMenu, 0);    // pSubMenu = 0, the handler of "File"
    int menuID = GetMenuItemID(pSubMenu, 3);   // menuID = -1, the ID of File --> Exit
    uint WM_COMMAND = 0x0111;
    SendMessage4(this.ptrToWindow, WM_COMMAND, menuID, null);
}

我使用VS2008，测试中的应用程序用C＃编码。菜单结构为：

I use VS2008, and the application under test is coded in C#. The menu structure is:

推荐答案

因为上面的代码来自自动化测试，而不是来自被测试的应用程序，所以我不能使用menustrip.handle属性。似乎win32 API函数可以帮助我，但GetMenu和GetSubMenu函数不起作用。我感到很困惑。

Because the above code is from the automated test, not from the application under test, I can not use menustrip.handle property. It seems win32 API functions can help me, but the GetMenu and GetSubMenu functions don't work. I feel so confused.
