Copying from unsigned char * to the CString

[usman999_1]

Right.
A possible better approach is to write your own "buffer" class like for example:

class CBuffer
{
   unsigned char* buffer;
   unsigned int length;
public:
   CBuffer() : buffer(NULL), length(0) {};
   SetBuffer(unsigned char* src, unsigned int length); 
   unsigned int GetLength() {return length;}
   // and so on, and so on... all you need
};

What is wrong with std::string???

Try this

void DoSomethingWithBinaryData(char* szData, unsigned int nLen)
{

std::string BinaryData;

BinaryData.assign(szData, nLen);

// Now you have access to all those handy functions of std::string and what not

// And to get the data back
 DoSomethingElseWithThisBinaryData(BinaryData.data(), BinaryData.size());
}

Now why would you need a buffer class with managing memory yourself???
