用TBlobStream;
void __fastcall TForm1::Button3Click(TObject *Sender)
{
TBlobStream *pStream;
Table1->Edit();
if (Table1->State == dsEdit)
{
pStream = Table1->CreateBlobStream(Table1->FieldByName("Notes"),
bmReadWrite);
try
{
AnsiString S = "This line will be added to the end";
pStream->Seek(0, 2); // Seek 0 bytes from the stream's end point
pStream->Write(S.c_str(), S.Length());
Table1->Post();
}
__finally
{
delete pStream;
}
}
}Top
