How to change a Memo.text

saxy

I try to change a value of a memo.... [img]style_emoticons/<#EMO_DIR#>/cool.gif" style="vertical-align:middle" emoid="B)" border="0" alt="cool.gif" /> I've a picture with a OnClick-Event at a fastreport page. At this event I want to read out any values of a ini-File to show them in a memo.text To read out the ini-file isn't a problem.[/img][img]style_emoticons/<#EMO_DIR#>/laugh.gif" style="vertical-align:middle" emoid="" border="0" alt="laugh.gif" /> Also to assign the value to the memo is running[/img]

Memo3.Text := Ini.ReadString('MEMO_'+dlgComboBox01_cmbSelection.Text,'Memo3.Text','');
ShowMessage(Memo3.Text);

<<== Answer is OK

At the Fast-Report-Page there isn't any effects shown. It shows the old value [img]style_emoticons/<#EMO_DIR#>/unsure.gif" style="vertical-align:middle" emoid=":unsure:" border="0" alt="unsure.gif" /> At an other test I use also[/img]

Report.ShowReport;

// <== access violation 4002E866 + 00A rtl70.bpl , TList.GetItems

It changes the values at the report page but an access violation is also shown.

TfrxMemoView(Memo3).Text:='Hello World';
TfrxMemoView(ReportTitle1.FindObject('Memo3')).Text:='Hallo Du da';

Don't give a better result.

Who know an solution to change values of a memo.text, memo.hint and a memo.descrition while the preview and by using somethink like a button-press

Thank in advance " border="0" alt="laugh.gif" />" alt=">" />

There's a demo for that, at least to change the text value, I don't think it's possible to change the description or the hint of the object in the preview window, as you don't get a valid/direct handle to the objects (hence the exceptions you are getting).
See the Interactive report demo.

[img]style_emoticons/<#EMO_DIR#>/huh.gif" style="vertical-align:middle" emoid=":huh:" border="0" alt="huh.gif" /> ==> At the demo you called, I've the same effect. OK, you are able to change the Value of the[/img]sender but not of an other memo then the sender. This is my probleme to solve.

.....
 TfrxMemoView(Sender).Text := InputBox('Edit', 'Edit Memo2 text:', s);  //Memo2 is the sender
 Memo1.Text:= Memo2.Text;          // <== I need to change the value of Memo1 also!!!
 Modified := True;

Probleme solved!!!!! [img]style_emoticons/<#EMO_DIR#>/tongue.gif" style="vertical-align:middle" emoid=":P" border="0" alt="tongue.gif" /> I changed[/img]Modified := true;
to
Modified := false;
It's running now..

Solution:

....
Memo3.Text := Ini.ReadString('MEMO_'+dlgComboBox01_cmbSelection.Text,'Memo3.Text','');
Memo3.Hint := Ini.ReadString('MEMO_'+dlgComboBox01_cmbSelection.Text,'Memo3.Hint','');
Memo3.Description := Ini.ReadString('MEMO_'+dlgComboBox01_cmbSelection.Text,'Memo3.Description','');                                    
  
MemoName:='Memo50';                          
TfrxMemoView(ReportTitle1.FindObject(MemoName)).Text:='Hallo Du da';                                       
    
Report.ShowReport;                                                                      
Modified := false;
....

It's used for changing the report-language dynamicly

Thanks for your interest and support

Best regard.....
