The compiler writes that it cannot convert std::string to AnsiString (and Edit2->Text is AnsiString ). Make Edit2->Text = password_chars.c_str() ;

  • The char * string must end with a null character, otherwise it will be considered incomplete, and garbage that is in memory after the characters that you initialized can enter into it. Add the '\0' character to the end of the array. - Vladimir Pavluk
  • @ Shouldn't it be added automatically? - aaa
  • one
    And why should it be added automatically if you specify a string in an array? After all, the compiler does not understand that you want to make a string from this array. Now, if you had written char s_russian[] = "àáâãäå¸æçèéêëìíîïðñòóôõöøùúûüýþÿ"; , then the compiler would add 0 at the end of the line automatically. - Vladimir Pavluk

If possible, it is better not to interfere with the Border AnsiString with std::string . And instead of AnsiString use just a String , which will unfold in Ansi- or Unicode- , depending on the project settings.

In this case, the problem can be solved by creating an AnsiString object using a constructor that takes a pointer to a char and the number of elements.

 Edit2->Text = AnsiString(s_russian, sizeof(s_russian));

Or replace the original array with a string literal:

 const char* s_russian = "русские_буквы"; Edit2->Text = s_russian;
