Win32 SDK基础(七)之如何创建一个窗口的子窗口的案例

HWND WINAPI CreateWindow(
_In_opt_ LPCTSTR lpClassName,
_In_opt_ LPCTSTR lpWindowName,
_In_ DWORD dwStyle,
_In_ int x,
_In_ int y,
_In_ int nWidth,
_In_ int nHeight,
_In_opt_ HWND hWndParent,
_In_opt_ HMENU hMenu,
_In_opt_ HINSTANCE hInstance,
_In_opt_ LPVOID lpParam
);

int APIENTRY wWinMain(_In_ HINSTANCE hInstance,
_In_opt_ HINSTANCE hPrevInstance,
_In_ LPWSTR lpCmdLine,
_In_ int nCmdShow)
{
// TODO: Place code here.

g_hInstance = hInstance;
BOOL nRet = Register("Main", WndProc);
if (!nRet)
{
MessageBox(NULL, "注册失败", "Infor", MB_OK);
return 0;
}
HWND hWnd = CreateMain("Main", "window");

CreateWindow("Main", "子窗口",
WS_OVERLAPPEDWINDOW|WS_CHILD|WS_VISIBLE|WS_POPUP, CW_USEDEFAULT, CW_USEDEFAULT, 400, 200,
hWnd, NULL, g_hInstance, NULL);


Display(hWnd);
Message();
return 0;
}
