1、使用itoa(int to string) 1//char *itoa( int value, char *string,int radix);2//原型说明:3//value:欲转换的数据。4//string:目标字符串的地址。5//radix:转换后的进制数,可以是10进制、16进制等。6//返回指向string这个字符串的指针78int aa =30;9char c[8];10 itoa(aa,c,16);11 cout<...

1st) you declared larray as const char*, and yet you assigned a value to itThat's not a problem. nevermore28 wrote: if you want to assign a c - string to std::string, use the string member function assign:No need to do that The problem is that you provide a std::string to pr...
If you want a copy of the string for later destruction, then I would probably do something more like:prettyprint Копировать const char* CSVMTrainDlg::convtCStrToChar(CString const & strParam) { CStringA cstraParam(strParam); size_t len = cstraParam.GetLength()+1; char ...

I tried to explain this in my first post, where I mention that it won't work if the CString is destroyed before the pointer is used. If you want a copy of the string for later destruction, then I would probably do something more like: prettyprint 複製 const char* CSVMTrainDlg::...
