(C++ Builder) How do I display a memory address on screen?

Convert the memory address to a std::string, then convert the std::string to a String.

Note that when converting this address to either an integer or a String, this yields the same result.

include <string>

include <sstream>

std::string toString(const String& ansi)
{
  const char * myChar = ansi.c_str();
  const std::string myString = myChar;
  return myString;
}
//---------------------------------------------------------------------------
String toAnsiString(const std::string& myString)
{
  const char * myChar = myString.c_str();
  const String myAnsi = myChar;
  return myAnsi;
}
//---------------------------------------------------------------------------
std::string addressToString(const void* x)
{
std::ostringstream o;
if (!(o << x)) return "ERROR";
return o.str();
}
//---------------------------------------------------------------------------
int addressToInt(const void* x)
{
  const std::string myString = addressToString(x);
  return atoi(myString.c_str());
}
//---------------------------------------------------------------------------
String addressToAnsi(const void* x)
{
  const std::string myString = addressToString(x);
  return toAnsiString(myString.c_str());
}
//---------------------------------------------------------------------------
void __fastcall TForm1::Button1Click(TObject *Sender)
{
  ShowMessage(addressToInt(this));
  ShowMessage(addressToAnsi(this));
}
//---------------------------------------------------------------------------
