[Solved]TBookMark lazarus / 16-Databases ---------------------------------------------------------------------- martin17476 · 2016-02-02 11:18 Hello, I am new in Lazarus but wiht experience in Delphi.  It is the first time here at the forum and I apologize if I am not doing correctly. I am migrating from Delphi an old program and I have one error that I can not resolve. This is the fragment of the program: procedure TfAlbaranes.dblcbBuscarCliClick(Sender: TObject); var tbmMarca : TBookMarkStr; fSuma : Currency; begin     dmPages.qVehCli.Close;     intCodCli := dmPages.tClientesCodigoInterno.AsInteger;     dmPages.qVehCli.Params[0].AsInteger := intCodCli;     dmPages.qVehCli.Open;     tbmMarca := dmPages.tAlbaranes.GetBookMark;  and the error: identifier not found "TBookMarkstr" I tried also with BookMark with the same error. Thankyou  very much ---------------------------------------------------------------------- Mando · 2016-02-02 11:36 Hello: change this: var tbmMarca : TBookMarkStr; by tbmMarca : TBookMark; Regards, saludos. ---------------------------------------------------------------------- martin17476 · 2016-02-02 11:50 Thank you very much, but the problem is the same.
