  Hello all,
  i have got plenty memos with float values in it. I need to add these values.
  ShowMessage(FloatToStr(Memo1.Value)) gives an empty Message back. XY := StrToFloat(Memo1.Text) gives an error back (xx,xx is a invalid floating point value).
  
  How can i get the values of the Memos?
  
  Thx 4 help.

  
  Hi.
  
  The 'value' property I think is only available inside the OnGetValue-event. Else you shold access the text property.
  
  Try: ShowMessage(Memo1.text);

  Hi,
  thanks 4 your anwser, but this didn't help.
  There is no OnGetValue-event to choose on Memos, DetailData, MasterData.
  In all other events (onAfterPrint, onBeforePrint, onAfterData,...) the 'value' property isn't available too.
  
  edit:
  showmessage(memo1.text) returns the correct memo-content.
  
  edit2:
  if i manually fill values in the memo, memo1.values is empty.
  if the memo receives the values from DetailData or MasterData, the value property is accessable. crazy huh?

  Sorry about that. I meant OnAfterData-event.
  And then, the value only returns what comes from fields or variables inside the memo, not from text.
  Example: '[mydb."myfield"] my text' in a memo will return the contens of mydb."myfield" as value (and ignore 'my text').

  AND if the memo contains more than 1 field or expression only the last one processed is in the value
