文本文件包含以下数据

Hello everyone :)

				} 
		}
	}

But in the output screen when i open a file im not getting anything .. Please Help

推荐答案

你正在使用 _tprintf_s 哪个将格式化的字符串打印到 stdout ，如上所述在MSDN上 [ ^ ]。您需要在文件读取代码中创建内部结构，数组或类似内容，它将以某些有用的顺序包含所有令牌。然后在 OnPaint 方法中，将该数据呈现到SDI客户端视图中，并根据您的要求进行制表。文章部分有很多样本可以告诉你如何操作。

You are using _tprintf_s which prints a formatted string to stdout, as described here on MSDN[^]. You need to create an internal structure, array or similar in the file reading code, which will contain all your tokens in some useful order. Then in your OnPaint method you render that data onto your SDI client view, tabulated according to your requirements. There are lots of samples in the articles section that should show you how to do it.
