我尝试将Win32应用程序转换为DLL。但是我对STL载体有一些困难。在原始应用程序中一切正常,但在DLL“访问冲突读取位置”错误发生。这是.h
的代码 #ifdef NNETDLL_EXPORTS
#define NNETDLL_API __declspec(dllexport)
#else
#define NNETDLL_API __declspec(dllimport)
#endif
#include <vector>
using namespace std;
#define VECARRAY vector<double>
class NNETDLL_API CNNetDll
{
public:
CNNetDll(void);
virtual ~CNNetDll();
int m_InputNeurons, m_HiddenNeurons, m_OutputNeurons;
/* Активаторы */
vector<double> inputs;
vector<double> hidden;
vector<double> actual;
/* Вход скрытых ячеек(со смещением) */
vector<VECARRAY> who;
/* Вход выходных ячеек(со смещением) */
vector<VECARRAY> wih;
int InitializeNetwork(CString FileName);
void feedForward();
void ActionNN(/*VECARRAY input_vec, VECARRAY& output_vec*/);
void ReadNN(CString FileName);
};
这是.cpp的代码,其中发生异常
int CNNetDll::InitializeNetwork(CString FileName)
{
int i, hid, inp, out;
CFile f;
CString s;
TCHAR szDrive[200];
TCHAR szDir[200];
TCHAR szFile[200];
TCHAR szExt[200];
_wsplitpath_s(FileName, szDrive, szDir, szFile, szExt);
SetCurrentDirectory(szDir);
s = szExt; FileName = szFile + s;
f.Open(FileName, CFile::modeRead);
f.Read(&m_InputNeurons, sizeof(double));
f.Read(&m_HiddenNeurons, sizeof(double));
f.Read(&m_OutputNeurons, sizeof(double));
for (i = 0; i < m_InputNeurons; i++)
{
inputs.push_back(0.0); // !!!!! ERROR IS HERE !!!!!!
}
for (i = 0; i < m_HiddenNeurons; i++)
{
hidden.push_back(0.0);
}
for (i = 0; i < m_OutputNeurons; i++)
{
actual.push_back(0.0);
}
for (i = 0; i < m_HiddenNeurons + 1; i++)
{
who.push_back(actual);
}
for (i = 0; i < m_InputNeurons + 1; i++)
{
wih.push_back(hidden);
}
for (hid = 0; hid < m_HiddenNeurons; hid++)
{
for (inp = 0; inp <= m_InputNeurons; inp++)
{
f.Read(&wih[inp][hid], sizeof(double));
}
}
for (out = 0; out < m_OutputNeurons; out++)
{
for (hid = 0; hid <= m_HiddenNeurons; hid++)
{
f.Read(&who[hid][out], sizeof(double));
}
}
f.Close();
return 1;
}
该应用程序试图填充向量。 callstack的最后一步是在这个行的“xutility”文件中:
inline void _Container_base12::_Orphan_all()
{ // orphan all iterators
#if _ITERATOR_DEBUG_LEVEL == 2
if (_Myproxy != 0)
{ // proxy allocated, drain it
_Lockit _Lock(_LOCK_DEBUG);
for (_Iterator_base12 **_Pnext = &_Myproxy->_Myfirstiter;
*_Pnext != 0; *_Pnext = (*_Pnext)->_Mynextiter) // !!!!LAST OPERATION BEFORE EXCEPTION!!!
(*_Pnext)->_Myproxy = 0;
_Myproxy->_Myfirstiter = 0;
}
#endif /* _ITERATOR_DEBUG_LEVEL == 2 */
}
重复,在原始应用程序中,正常工作正常。另外我注意到,该向量产生了错误,该声明在CNNetDll类中首先出现。在上面的代码中,它是矢量“输入”。如果我改变这样的声明
vector<double> hidden;
vector<double> actual;
vector<double> inputs;
然后在此代码中使用“隐藏”向量出现异常
for (i = 0; i < m_InputNeurons; i++)
{
inputs.push_back(0.0); //!!!! works properly !!!!!
}
for (i = 0; i < m_HiddenNeurons; i++)
{
hidden.push_back(0.0); // !!! exception here !!!
}
for (i = 0; i < m_OutputNeurons; i++)
{
actual.push_back(0.0);
}
对象创建和函数调用:
CNNetDll nn;
nn.InitializeNetwork(_T("M:\\Tasks\\2016\\Win8-64\\AI\\NNet\\Debug\\NN.dat"));
如何解决这个问题????
答案 0 :(得分:1)
问题在于错误的变量定义(使用int数据类型)并将double数据类型的大小存储到这些变量中。匹配类型都可以很好地工作。
int m_InputNeurons, m_HiddenNeurons, m_OutputNeurons;
