How to convert String to AnsiString

Dear all

I got one problem with builder c++ AnsiString to string.
when i use ifstream this arg to read file from local system
and then after in i want to show message in my AP which i can called
ShowMessage this method and then in this method only support
AnsiString so on .
i need to convert string to AnsiString in showmessage. i hope someone can give one right direction to fix this problem

thank's

Code:

---

void __fastcall TForm1::Button1Click(TObject *Sender)
{      string str;
        AnsiString s;
        ifstream fin;
        fin.open("config.ini");

        if(fin.is_open()){
          ShowMessage("a");
          while(getline(fin,str)){

          s = AnsiString(); // convert string to AnsiString
          //ShowMessage("a" + s);
          }

        }
}

Convert a std::string to a LPCSTR (const char *) using std::string::c_str () method

Like this -

Code:

---

  std::string strTest ("This is a test string");
  const char* pszConverted = strTest.c_str ();

---

Code:

---

string s("gfd");
AnsiString s = AnsiString (s.c_str());

Sorry for a "silly" question... What is the AnsiString ? I haven't found it in MSDN... :confused:
______________
Ahhh! Never mind!
It is C++ Builder, not a MS! :D

Thank's everybody help
yes that's c++ builder method called AnsiString , but that problem is
in c++ builder any compoment support AnsiString not for string , so i need to find out any convert i can convert string to AnsiString
something like it

Code:

---

  string str1 = "1.roger 2.chunag 3.abc 4.ccc";
  replace(str1.begin(), str1.end(), ' ', '\n');
  Memo1->Text =  str1 ; // it wasnot work becuase cannot convert string to  ansistring

the output of Memo1 i want to be like this one

1.roger
2.chuang
3.abc
4.ccc

The way you are using the replace method for your string variable will not work correctly. It's better to iterate over your string, and using Builder's TMemo->Lines->Append function breaking the String up something like this works...

string str1 = "1.roger 2.chunag 3.abc 4.ccc";
AnsiString newline;

for(int i=0; i<str1.length(); i++)
{
if(str1[i]!=' ')
newline=newline+str1[i];
else
{
Memo1->Lines->Append(newline);
newline="";
}
}
Memo1->Lines->Append(newline);

So why did you post in the Visual C++ Programming forum?

You should have posted to the Non-Visual C++ forum. Questions concerning Borland C++ builder's library are off-topic here.
