copy of a variable's value

Hi

I've created a variable's value "var1" ongetvalue evenement but when i want to do a copy([var1],1,3) in order to have the first three letter of my variable, it posts me "[va".
WHY ?

Thanks

    Look at what you passed in in the ongetvalue event.
    you probably included a [ within the string.

    No, the value that i obtain is ok.

    This is my code :
    procedure OnGetValue :
    begin
       if AnsiComparetext(VarName, 'var1') = 0 then
         Value := 'coucou';
    end;
    

    In my report, the variable's value is in a TFrxmemo.
    But when i want to do a copy(Memo3.text,1,6), it shows me "[var1]" instead of "coucou".

    I've tryed "copy([var1],1,6)" but an error message appears "Undeclared identifier <cell1>". I've also tested without [] but it's similar.

    ok what you are doing is trying to copy the memos.text property which is [var1], u
    you want the value of the variableand you must watch 2 things,
    since you are retrieving the value of the var in the ongetvalue event you can't process it until after it retrieves a value. so write your expression in the memo this way [Copy([var1],1,3)]

    I already tested that but when my report appears, an error message appears too !!
    "Undeclared identifier var1". ;)

    My variable is into a Memo in a MasterData and the other Memo where i want to do a copy of my variable is in a GroupFooter, is it important ?

    this assume you created var in report's datadictionary named var1 and did not set any expression value to it.
    your onget value code is bad

    should be
    if AnsiComparetext(parName, 'var1') = 0 then
    parValue := 'coucou';

    not with the fastReport version 3.05 !

    I've tested on Windows NT4 and an error appears but with Windows XP, I've not got error. Why ?

    if you are using fr3 please post questions for fr3 in fr3 forum
    the answer i gave you was for fr2.53.
    in version 3
    you must use the get method with the variable
    [copy(get('var1'),1,3)]
    ;)
