win7 64获取托盘图标句柄错误

careysucci 2015-12-28 01:02:47

通过下面方法获取托盘图标的句柄是错误的，返回值不是托盘图标的句柄，
请问大神为什么获取到的托盘图标句柄错了？谢谢

获取子窗口句柄使用API FindWindowEx FindWindowEx The FindWindowEx function retrieves a handle to a window whose class name and window name match the specified strings. The function searches child windows, beginning with the one following the given child window. This function does not perform a case-sensitive search. HWND FindWindowEx( HWND hwndParent, // handle to parent window HWND hwndChildAfter, // handle to a child window LPCTSTR lpszClass, // pointer to class name LPCTSTR lpszWindow // pointer to window name ); Parameters hwndParent Handle to the parent window whose child windows are to be searched. If hwndParent is NULL, the function uses the desktop window as the parent window. The function searches among windows that are child windows of the desktop. Windows NT 5.0 and later: If hwndParent is HWND_MESSAGE, the function searches all message-only windows. hwndChildAfter Handle to a child window. The search begins with the next child window in the Z order. The child window must be a direct child window of hwndParent, not just a descendant window. If hwndChildAfter is NULL, the search begins with the first child window of hwndParent. Note that if both hwndParent and hwndChildAfter are NULL, the function searches all top-level and message-only windows. lpszClass Pointer to a null-terminated string that specifies the class name or is an atom that identifies the class-name string. If this parameter is an atom, it must be a global atom created by a previous call to theGlobalAddAtom function. The atom, a 16-bit value, must be placed in the low-order word of lpszClass; the high-order word must be zero. lpszWindow Pointer to a null-terminated string that specifies the window name (the window's title). If this parameter is NULL, all window names match. Return Values If the function succeeds, the return value is a handle to the window that has the specified class and window names. If the function fails, the return value is NULL. To get extended error information, callGetLastError. QuickInfo Windows NT: Requires version 4.0 or later. Windows: Requires Windows 95 or later.

获取子窗口句柄使用API FindWindowEx

FindWindowEx
The FindWindowEx function retrieves a handle to a window whose class name and window name match the specified strings. The function searches child windows, beginning with the one following the given child window. This function does not perform a case-sensitive search.

HWND FindWindowEx(
HWND hwndParent, // handle to parent window
HWND hwndChildAfter, // handle to a child window
LPCTSTR lpszClass, // pointer to class name
LPCTSTR lpszWindow // pointer to window name
);

Parameters
hwndParent
Handle to the parent window whose child windows are to be searched.
If hwndParent is NULL, the function uses the desktop window as the parent window. The function searches among windows that are child windows of the desktop.

Windows NT 5.0 and later: If hwndParent is HWND_MESSAGE, the function searches all message-only windows.

hwndChildAfter
Handle to a child window. The search begins with the next child window in the Z order. The child window must be a direct child window of hwndParent, not just a descendant window.
If hwndChildAfter is NULL, the search begins with the first child window of hwndParent.

Note that if both hwndParent and hwndChildAfter are NULL, the function searches all top-level and message-only windows.

lpszClass
Pointer to a null-terminated string that specifies the class name or is an atom that identifies the class-name string. If this parameter is an atom, it must be a global atom created by a previous call to theGlobalAddAtom function. The atom, a 16-bit value, must be placed in the low-order word of lpszClass; the high-order word must be zero.
lpszWindow
Pointer to a null-terminated string that specifies the window name (the window's title). If this parameter is NULL, all window names match.
Return Values
If the function succeeds, the return value is a handle to the window that has the specified class and window names.

If the function fails, the return value is NULL. To get extended error information, callGetLastError.

QuickInfo
Windows NT: Requires version 4.0 or later.
Windows: Requires Windows 95 or later.
Windows CE: Unsupported.
Header: Declared in winuser.h.
Import Library: Use user32.lib.
Unicode: Implemented as Unicode and ANSI versions on Windows NT.
