Problem allocating class on heap...

Here's my main function, the problem lies almost in the first line where I delcare an instance of DynamicString on heap.

If you need more code, just let me know:

Code:

#include <fstream>  // This is required for file streams.
#include <iostream>
#include "email.h"// This is required for input/output streams. (ie cout)

using namespace std;

int main()
{
  ifstream emailFile( "Email.txt" ); // Open a file for inputing.
  ofstream fout( "EmailResponse-rjg5021.txt" );


  while( !emailFile.eof() )
  {
      DynamicString s = new DynamicString(  );
      emailFile.getline( s.Buffer, 1000 );

           
      Email anEmail( s.Buffer );
       

	if( anEmail.IsValid() )
    {
        //std:: cout << 1 << std::endl;
	    fout << 1 << endl;
    }
	else
    {
        //std:: cout << 0 << std::endl;
	    fout << 0 << endl;
    }
    s.~DynamicString();
  } 
  
  emailFile.close();   // All done so close the file.
  
  return 0;
}

The error is this:

error C2440: 'initializing' : cannot convert from 'DynamicString *' to 'DynamicString'
No constructor could take the source type, or constructor overload resolution was ambiguous

but the constructor is:

Code:

DynamicString()
	{
		Size = 0;
		Buffer = NULL;
	}

I've tried using the another constructor, but to no avail:

Code:

DynamicString(const char* buffer, int bufferSize = 0)
	{
		// Size not speciied?
		if ( bufferSize == 0 )
			// Figure it out by searching for the end of string
			bufferSize = GetStringLength(buffer);

		Size = bufferSize;
		Buffer = new char[Size];

		// Copy buffer
		Copy(buffer, Buffer, 0, bufferSize);
	}

Any ideas?

make your s variable a pointer, ie:
DynamicString * s = new DynamicString;

also, change this:
s.~DynamicString();

to:

delete s;

okay, after doing that and changing all .'s to ->'s, it now gives me a bad ptr error since it initializes it Buffer to NULL (0)...

How would I do that? I'm editing old code to use heap allocation to get rid of stack, so I have to get rid of stack-allocated buffers and remove string size limitations, which doesn't seem possible...?.

Get rid of DynamicString, whatever it is, if you can. Try std::string instead.
