哪个模块在Windows上实现CreateWindowW？

我刚刚在我的应用程序中遇到问题,我需要获取CreateWindowW函数的静态地址.像这样:

&ShowWindow;

但是,当使用相同的技巧时CreateWindowW,我得到编译器错误 Identifier "CreateWindowW" is undefined(它是一个宏).我实际上找不到这个函数的定义(哪个DLL),甚至pinvoke.net也没有提到这个.

在某些网站上有提及它user32.dll,但GetProcAddress对于我的函数,它返回null指针.我迷路了,Windows上哪个模块链接了这个功能？

如果我尝试将调试器和跟踪调用连接到此函数,Visual Studio会"跳过"它,所以我无法理解调用的位置.

我的构建是UNICODE.WinUser.h文本我可以看到:

#define CreateWindowA(lpClassName, lpWindowName, dwStyle, x, y,\
nWidth, nHeight, hWndParent, hMenu, hInstance, lpParam)\
CreateWindowExA(0L, lpClassName, lpWindowName, dwStyle, x, y,\
nWidth, nHeight, hWndParent, hMenu, hInstance, lpParam)
#define CreateWindowW(lpClassName, lpWindowName, dwStyle, x, y,\
nWidth, nHeight, hWndParent, hMenu, hInstance, lpParam)\
CreateWindowExW(0L, lpClassName, lpWindowName, dwStyle, x, y,\
nWidth, nHeight, hWndParent, hMenu, hInstance, lpParam)
#ifdef UNICODE
#define CreateWindow  CreateWindowW
#else
#define CreateWindow  CreateWindowA
#endif // !UNICODE

Cheers and h.. 6

CreateWindowExW出口user32.dll.您只需查看文档即可.或者您可以通过Microsoft的dumpbin工具检查导出.

> dumpbin /exports c:\windows\system32\user32.dll | find /i "CreateWindow"

       1618   6D 0000A230 CreateWindowExA
       1619   6E 000107B8 CreateWindowExW
       1620   6F 00041530 CreateWindowStationA
       1621   70 000014D0 CreateWindowStationW

CreateWindowW是一个实现为宏的瘦包装器,根据其文档:

" CreateWindow实现为对CreateWindowEx函数的调用,如下所示.

#define CreateWindowA(lpClassName, lpWindowName, dwStyle, x, y, nWidth, nHeight, hWndParent, hMenu, hInstance, lpParam)\
CreateWindowExA(0L, lpClassName, lpWindowName, dwStyle, x, y, nWidth, nHeight, hWndParent, hMenu, hInstance, lpParam)

#define CreateWindowW(lpClassName, lpWindowName, dwStyle, x, y, nWidth, nHeight, hWndParent, hMenu, hInstance, lpParam)\
CreateWindowExW(0L, lpClassName, lpWindowName, dwStyle, x, y, nWidth, nHeight, hWndParent, hMenu, hInstance, lpParam)

#ifdef UNICODE
#define CreateWindow  CreateWindowW
#else
#define CreateWindow  CreateWindowA
#endif

您还可以通过例如Visual Studio中的"转到定义"来检查.
