manipulating components

Hi
I am managing old Delphi 7 code
I have a form with many TEdit
I use the following code to clear values on my form
My problem is I cannot figure out how to stop certain values from clearing
Example
Edit1.text =’Main Information’
Edit2.text =’General Information’
Edit3.text =’General Information’
Edit4.text =’General Information’

When I use the my following procedure
I need to stop Edit1.text =’Main Information’ from clearing

procedure TForm1.Clear_values
var
j : Integer;
begin
for j := 0 to ComponentCount-1 do
begin
for j := 0 to ComponentCount-1 do
begin

if TEdit(Components[j]).Parent.Name = 'edit2' then showmessage('TEST');

   if (Components[j] is TEdit) then
     (Components[j] as TEdit).Text := '';
   if (Components[j] is Tcheckbox) then
     (Components[j] as Tcheckbox).checked := false;
   if (Components[j] is TRadioButton) then
     (Components[j] as TRadioButton).checked := false;
    if (Components[j] is TComboBox) then
     (Components[j] as TComboBox).Itemindex := -1;
    if (Components[j] is Tmemo) then
     (Components[j] as Tmemo).text := '';
end;

Thank you

one thing that strikes me as very odd ...
the dubble loop with the same j variable ???

why twice ?

As a passing comment, please tell me that you are not actually using components on your form with names like Edit1, Edit2, and Edit3 but are, instead, providing meaningfull names for each of them. ;-)

that's not all that bad
as long as they can remember what Edit34 is for on Form234 out of 654 forms

but don't ever ask me to come and personally help to debug
because i've had that nightmare in once place, and they are never ever seeing me back again !

Geert,
I didn't know you ever worked in Memphis, TN, but you must have because I ran into that sort of nameing convention in several places there . . . none of which would I return to and all of which I raised my rates after seeing the code and before finalizing the contracts.  (I thought it was only a couple of spots in the code each time but figured out later that it was pervasive.)

grrr, i don't do that.
I said I had a problem with debugging that.

After the umpteenth question
What was Edit34 for again ?
I forgot after you told me what Edit23, Edit26, Combobox45, Combobox45_2 and Edit45beta was for
I think I mixed it up with Edit43 ...
Was that for the first name or the last name of the vendor ?
What was Combobox45_2 again ?

Ow, can I ask a silly question ?
I don't completely follow why you use underscore 2, or underscore 3 in your code,
and then later you seem to use beta and gamma.
Not that it's any of my business but that's rather frustrating ...
It's a lot simpler just using the names given by Delphi ?

Ah no, we just had a new recruit and we told him to come up with a better naming convention.
What do you think about it ? I think it's rather good ...

Me: Ow god, what have I gotten myself into now ... Where is the beer ?

Geert,
Where is the beer ?

I actually billed a client (one that had the rate raised per above ;-) for the after work brews one time . . . it was covered under the consultant will be reimbursed for all misc expenses clause. ;-)
