标题: 【求助】proe开发套用tkuse实例遇到的问题
套用tkuse中建section的例子编程中却出现：
error C2440: 'return' : cannot convert from 'const int' to 'enum ProErrors'
                   Conversion to enumeration type requires an explicit cast
                   (static_cast, C-style cast or function-style cast)
因基础太差百思不得其解，请高手指点！

十万火急，求大家帮忙！！！

可不可以将你出错的程序段贴出，这样方便大家看看。

作者: NOCTURE 时间: 2003-5-23 23:41
就是下面这一段（tkuse中sections那一张的例子）我才可能是需要一个“显性类型转换”？恳请大家指点。

错误出在哪条语句上？

作者: NOCTURE 时间: 2003-5-24 11:24
就是那些"return(-1)""return(0)"的地方。
好像说我的返还值类型不对，可原来给出的例子就是这样的呀::?::?::?::?

作者: zjcbhy 时间: 2003-5-24 11:33
将return(0)换成return(PRO_TK_NO_ERROR)
将return(1)换成return(PRO_TK_GENERAL_ERROR)
试试

compile时没有问题，可在rebuide时出现了如下问题

Linking...
LINK : warning LNK4075: ignoring /INCREMENTAL due to /FORCE specification Creating library Debug/section.lib and object Debug/section.exp
section.obj : error LNK2001: unresolved external symbol "enum ProErrors __cdecl ProDemoSectCreate(void)" (?ProDemoSectCreate@@YA?AW4ProErrors@@XZ)
Debug/section.dll : warning LNK4088: image being generated due to /FORCE option; image may not run

section.dll - 1 error(s), 2 warning(s)
原文中是分几步一段一段地介绍函数的，其中ProSectionSolve()的介绍中出现了if (status != PRO_TK_NO_ERROR)
       return(-1);
这种情况。而在最后的范例中却是把各步集成了一个函数，出现了上述问题。

再回头看看例子，我发现这一段我始终没搞明白
*************************************************
The following code fragment shows a call to ProSectionSolve()
and an analysis of the errors produced.
*********************************************
ProWSecerror  errors;
int                n_errors, e;
ProError       status;
ProMsg          wmsg;
char             msg[PRO_PATH_SIZE];
int                ent_id;
ProSecerrorAlloc ([$errors)]
status = ProSectionSolve (section, [$errors)]
if (status != PRO_TK_NO_ERROR)
{
   &nbsp

roSecerrorCount ([$errors, &n_errors)]
    for (e = 0; e < n_errors; e++)
   {
     &nbsp

roSecerrorMsgGet (errors, e, wmsg);
     &nbsp

roWstringToString (msg, wmsg);
     &nbsp

roSecerrorItemGet (errors, e, [$ent_id)]
      printf ("%s: Problem ID, %d\n", msg, ent_id);
    }
ProSecerrorFree ([$errors)]
return (-1); 这里的“-1”到底表示什么意思？指什么？ ::?
}
请指教！！！

因为在运行之前有个注册
#indefine ok 1
#indefine cancel 0
它就表示了这个动作
无需其他

作者: lxf999999 时间: 2003-8-5 16:13
转换出错了，一个是整形，一个是枚举
改一下属性
或者你的库文件少了
