本演练是错误的[演练：创建Windows桌面应用程序（C ++）VS2015] https://msdn.microsoft.com/en-us/library/bb384843.aspx [英] This walkthrough is wrong [Walkthrough: Creating Windows Desktop Applications (C++) VS2015] https://msdn.microsoft.com/en-us/library/bb384843.aspx

问题描述

我按照演练进行了操作，但在

I followed the walkthrough and it failed at

if (!RegisterClassEx(&wcex))

我怀疑这是因为代码的这一行：

I suspect this happened because of this line of the code:

WNDCLASSEX wcex;

// WNDCLASSSEX结构的各种其他成员的初始化

//initialization of the various other members of the WNDCLASSSEX struct

wcex.lpszClassName = szWindowClass;

wcex.lpszClassName = szWindowClass;

因为标识符 szWindowClass 永远不会在代码中定义，从而产生编译错误，我试过这个：

since the identifier szWindowClass is never defined in code, thus giving a compilation error, I tried this:

wcex.lpszClassName  = LPCTSTR("Win32 Walkthrough Window")

On a side note, is Windows API this esoteric on purpose or was the system architect on crack?

推荐答案

您没有注意到漫游代码声明变量的位置。  再看一下 -

You didn't notice where the walkthrough code declared the varialble.  Look again for --

static TCHAR szWindowClass[] = _T("win32app");
static TCHAR szTitle[] = _T("Win32 Guided Tour Application");
