Values in Memos

Spielhallen_Frank

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
