Come tutti sappiamo, creare un webServer con Delphi è semplicissimo, cosa meno banale è invece decodificare una post che che contiene un multipart/form-data. Quando una paginetta http esegue una http submit da un form in metodo post, magari con un file in upload il browser genera uno stream codificato in UTF8 in cui ci sono…

Con FastReport 4 esportare un report in PDF su stream è semplicissimo, bastano 5 minuti … peccato che non è spiegato nella documentazione, quindi per capire come funzionava l’arcano ci ho perso due ore… di seguito una porzione di codice come esempio: procedure TForm1.Button3Click(Sender: TObject); var st : TMemoryStream; begin st := TMemoryStream.Create; Try TBlobField(csReports.FieldByName(‘Report’)).SaveToStream(st);…
