一个头文件问题(100分)

WINAPI 在windows.h里面定义的吧<br><br>把windows.h include进去吧

感谢wrench的帮助，我已解决WINAPI问题，<br>不过还有一个TDate问题，它应该是一个类吧，但有报错：<br>[C++ Error] MYDLL.H(13): E2451 Undefined symbol 'TDate'<br>

是什么 C++ ?<br>BCB: #include &lt;vcl.h&gt;<br>VC : 使用 MFC

#include &lt;controls.h&gt;

#include &lt;controls.h&gt;

#include "controls.h"<br><br>气死了 被尖括号搞两次 只好用引号

真不好意思，还有一个问题：<br>有一处#include "CCALENDAR.h"<br>&nbsp;出错：<br>[C++ Error] TIMEFORM.H(10): E2209 Unable to open include file 'CCALENDAR.h'<br>

是BCB

查找这个文件 <br>拷贝到工程的目录下来

接受答案了.
