Question

我正在做一个学校项目，因此我想进行设置，因此当用户按下按钮时，会弹出一个对话框，允许用户输入数据。我应该如何实施呢？如果需要的话，我会使用resedit。

我编写了一个简单的演示，您可以参考以下代码

编译器工具：VS2017

// WindowsProject29.cpp : Defines the entry point for the application.

#include "stdafx.h"
#include "WindowsProject29.h"

#define MAX_LOADSTRING 100

// Global Variables:

WCHAR szWindowClass[MAX_LOADSTRING];            // the main window class name
HWND hWnd;
