$ b编译时$ b，它给了我错误：
IDD_ABOUT没有命名类型
请让我知道问题是什么
on compilation , it gives me error:
IDD_ABOUT does not name a type
please let me know whats the problem
推荐答案
StackOverflow上的这个帖子似乎有答案：
This thread on StackOverflow seems to have the answer:
创建一个名为resource.h的包含文件，并在其中添加以下行：
Create an include file called resource.h and add this line to it:
#define IDD_ABOUT 100
然后将它包含在.cpp和.rc文件的顶部：
Then include it at the top of your .cpp and .rc files:
#include "resource.h" // add this line
它看起来就像你已经包含 resource.h 文件一样;您是否仔细检查过您是否在其中定义了 IDD_ABOUT 符号？
It looks like you've already included the resource.h file; have you double-checked that you've defined the IDD_ABOUT symbol in it?
//定义对话框看起来很奇怪：
The entire code block under//defining dialog boxlooks very odd:
IDD_ABOUT DIALOG DISCARDABLE 0, 0, 239, 66

好像你用一个工具复制粘贴了这个工具，以某种方式随机消除了许多非字母字符，如括号和逗号。
有很多符号应该分开，但不是，所以即使你设法解决了IDD_ABOUT错误，你也会遇到下一个未知符号或缺少分隔符。
要么仔细检查您的来源，并确保您拥有完整正确的代码，或者只是自己动手 - 这并不困难。
在旁注中，该代码中没有任何内容是C ++ - 这是纯粹的C。
Seems like you copy-pasted this with a tool that somehow eliminated lots of non-alpha characters such as parenthesis and commas at random.
There are a whole lot of symbols that should be separated, but are not, so even if you manage to fix that IDD_ABOUT error, you'll just run into the next unknown symbol or missing separator.
Either double check your source that you got the code from and make sure you really have the complete and correct code, or just do it yourself - it's not that difficult.
On a sidenote, nothing in that code is C++ - this is pure C.
我的第一个猜测IDD_ABOUT没有在resource.h中定义一些数字。
完整的对话框模板内容属于rc文件。它可以在Visual Studio的资源视图窗口中打开。它可能会抱怨其他错误。
My first guess is that the IDD_ABOUT isnt defined in the resource.h with some number.
The complete dialog template stuff belongs in a rc-file. It can be opened in a Resource View Window in Visual Studio. It may complain about other bugs.
