String allocation inside of external DLL

New comment
 
Another one Slawa:
No ability to allocate strings inside of DLL's. I need to pass string with fixed length, and use only that number of characters.
Will you change it some day?
Ruby
 
you can change string data in previously allocated buffer. new allocation or reallocation are unsafe therefore appropriate sample code in our SamleExpert.dll is absent
 
So how can I send string allocated in C++ to MQL4? It will cause memory leaks right since MQ4 will not delete it by itself.

I want something like:
string result = GetCPPString();

and the GetCPPString implementation in C++
char* GetCPPString ()
{
char* buffer = new char[100];
strcpy( buffer, "Hello..........." );
return (buffer);
}
How can I implement it so it will not cause any memory leaks or crashes?
