哪位大侠帮忙看下，为什么无法生成记录文件啊？

上面的程序报错access violation at address 32658731 in module'CC3260MT.DLL'.Read of address 00000000.
并指向strcat(strPathName, m_strFileName);这行

网上查大概是内存分配的问题，指针没用好。
我是实在不知道怎么改了。求大侠帮忙。谢谢了

[解决办法]
但是还是有问题，因为
m_strPath，m_strFileName没有任何数据你就调用那个函数，最终应该是这样的:

C/C++ code

  m_strPath = new char[200];  m_strFileName = new char[100];  memset(m_strPath, 0, sizeof(m_strPath));  memset(m_strFileName, 0, sizeof(m_strFileName));  Memo1->Lines->Add("发生器条码存在，等待匹配。");  //默认当前目录  char szExePath[MAX_PATH];  GetModuleFileName(NULL, szExePath, MAX_PATH);  *(strrchr(szExePath, '\\')) = '\0';  strcpy(m_strPath, szExePath);  sprintf(m_strFileName, "%s.txt",DateToStr(Now()));  WriteFIle("发生器条码存在，等待匹配。",1);
[解决办法]
呵呵,我也刚看出来,你的
WriteFIle("发生器条码存在，等待匹配。",1);
应该是在所有变量赋值之后
