I want to update a table from a text file. For every given string in a line
I want to use FieldByNumber to add it to the table but it's giving me an
access violation error on
TempTable->Fields->FieldByNumber(i+1)->AsVariant

Here's what my code looks like:

TempTable->Open();
TempTable->First();

            TempTable->Insert();
            for (int j=0;TempTable->Fields->Count > j; j++)
                {
                TempTable->Fields->FieldByNumber(i+1)->AsString=FieldValue;
                }
            TempTable->Post();
  TempTable->Close();
