问题描述

美好的一天，

我正在尝试使用名为Class，CMyClass的字符串创建一个CRuntimeClass指针，如下所示

Good day,

I am trying to create a CRuntimeClass pointer using a string with the name of the Class, CMyClass, as per below

CRuntimeClass * pClass = CRuntimeClass::FromName(L"CMyClass");

CMyClass已经被声明为DYNCREATE，基类为CRecordView。

无论花费多少精力，特定指针都会返回NULL。

在调试时，我注意到了以下代码：

QUOTE

CMyClass has been already declared as DYNCREATE with base class CRecordView.

No matter all efforts spent, specific pointer returns as NULL.

On debugging, i have noticed that in the following code:

QUOTE

CRuntimeClass* PASCAL CRuntimeClass::FromName(LPCSTR lpszClassName)
{
    CRuntimeClass* pClass=NULL;

    ENSURE(lpszClassName);

    // search app specific classes
    AFX_MODULE_STATE* pModuleState = AfxGetModuleState();
    AfxLockGlobals(CRIT_RUNTIMECLASSLIST);
    for (pClass = pModuleState->m_classList; pClass != NULL;
        pClass = pClass->m_pNextClass)
    {
        if (lstrcmpA(lpszClassName, pClass->m_lpszClassName) == 0)
        {
            AfxUnlockGlobals(CRIT_RUNTIMECLASSLIST);
            return pClass;
        }
    }

UNQUOTE

变量m_classList不包含我的CMyClass。

非常感谢任何帮助。

UNQUOTE

variable m_classList do NOT contain my CMyClass.

Any help is much appreciated.
