Unit

Category

extern PACKAGE bool __fastcall RenameFile(const AnsiString OldName, const AnsiString NewName);

Description

RenameFile attempts to change the name of the file specified by OldFile to NewFile. If the operation succeeds, RenameFile returns true. If RenameFile cannot rename the file (for example, if the application does not have permission to modify the file), it returns false.

#include 
void __fastcall TForm1::Button1Click(TObject *Sender)
{
  char szFileName[MAXFILE+4];
  int iFileHandle;
  int iLength;
  if (SaveDialog1->Execute())
  {
    if (FileExists(SaveDialog1->FileName))
    {
      fnsplit(SaveDialog1->FileName.c_str(), 0, 0, szFileName, 0);
      strcat(szFileName, ".BAK");
      RenameFile(SaveDialog1->FileName, szFileName);
    }
    iFileHandle = FileCreate(SaveDialog1->FileName);

    // Write out the number of rows and columns in the grid.
    FileWrite(iFileHandle, (char*)&(StringGrid1->ColCount), sizeof(StringGrid1->ColCount));
    FileWrite(iFileHandle, (char*)&(StringGrid1->RowCount), sizeof(StringGrid1->RowCount));
    for (int x=0;xColCount;x++)
    {
      for (int y=0;yRowCount;y++)
      {
        // Write out the length of each string, followed by the string itself.

        iLength = StringGrid1->Cells[x][y].Length();
        FileWrite(iFileHandle, (char*)&iLength, sizeof(iLength));
        FileWrite(iFileHandle, StringGrid1->Cells[x][y].c_str(), StringGrid1->Cells[x][y].Length());
      }
    }
    FileClose(iFileHandle);
  }
}
