错误C2064:使用VC ++时，该术语不求值 [英] error C2064: term does not evaluate to a function in using VC++

问题描述

 如果(！ValidateBaseMaterial())
        {
            sError.LoadString(IDS_ERR_BM_INACTIVE);
            AfxMessageBox(sError);
            返回；
        } 

解决方案

您没有正确定义或使用您似乎正在用作功能的符号.

可能的原因是:
-有关正确定义和使用函数指针的问题(请参阅解决方案1中的链接)
-如果还存在具有相同名称的本地符号，则无法为函数定义包括适当的标头

不幸的是，不幸的#define-macro会使您的代码混乱，但是代码中的符号看起来相当安全...


我的猜测是，不是将功能ValidateBaseMaterial的声明放入头文件中并包含该文件，而是将其复制到cpp文件中，并意外地省略了括号，如下所示:

int ValidateBaseMaterial; // <-- forgot the brackets!
 // ...
     if (!ValidateBaseMaterial())
          ^ error 2064!

另一种可能性是您在头文件中定义了类似的函数. http://msdn.microsoft.com/en-us/library/z72c1dfd (v = vs.80).aspx [if (!ValidateBaseMaterial()) { sError.LoadString(IDS_ERR_BM_INACTIVE); AfxMessageBox (sError); return; }

解决方案

You didn''t properly define or use a symbol that you appear to be using as a function.

Possible causes are:
- problems with the correct definition and use of function pointers (see the link in solution 1)
- failure to include the appropriate header for the function definition, if there is also a local symbol by the same name

There is also a slim chance that an unlucky #define-macro messes with your code, but the symbols in your code are looking fairly safe...


My guess is that instead of putting the declaration of the function ValidateBaseMaterial into a header file and include that, you copied it into your cpp file and accidenttaly ommitted the brackets like this:

int ValidateBaseMaterial; // <-- forgot the brackets!
 // ...
     if (!ValidateBaseMaterial())
          ^ error 2064!

Another possibility is that you defined the function like that right in your header file.

Check this, and find your case
