텍스트 에디터..?
를 만들면서 공부를 하고 있습니다.

BCB 6 에서 기본 지원하는 샘플 프로그램중
RichEdit를 참조해서 하고 있는 와중에

세이브, 로드를 위해.
밑의 코드를 가져다 붙였습니다.

void __fastcall TForm1::Button6Click(TObject *Sender)
{
    if( !strcmp(FFileName.c_str(), Reconst_SUntitled.c_str()) ){
    SaveAsClick(Sender);
    }else
    {
        memo->Lines->SaveToFile(FFileName);
        memo->Modified = False;
    }
    /*if (OpenDialog->Execute())
    {
        memo->Lines->LoadFromFile(OpenDialog->FileName);
        memo->SetFocus();
        memo->Modified = False;
        memo->ReadOnly = OpenDialog->Options.Contains(ofReadOnly);
    }     */
}

//---------------------------------------------------------------------------

void __fastcall TForm1::Button7Click(TObject *Sender)
{
    CheckFileSave();
    if (OpenDialog->Execute())
    {
        memo->Lines->LoadFromFile(OpenDialog->FileName);
        SetFileName(OpenDialog->FileName);
        memo->SetFocus();
        memo->Modified = False;

그랬더니 이런 에러가 나는군요;

[Linker Error] Unresolved external 'Reconst::_SUntitled' referenced from D:\YTS\TXT EDITOR\UNIT1.OBJ
[Linker Error] Unresolved external 'Reconst::_SConfirmation' referenced from D:\YTS\TXT EDITOR\UNIT1.OBJ

왜 그러는지 혹시 알 수 있을런지요?

....으헝 ㅠㅠㅠ

허접하게나마 제가 만든... 소스도 같이 올려봅니다...(근데 주석이 없군요.... 죄송합니다;)
