(Solved)How To?
«

October 09, 2020, 04:39:12 am »
So the following code throws an error if i turn on the second line.
Is there a way to make this work? I want to set the Text in TEdit.Text to TEdit1.Text := '';
I know that Tedit.Text will work but I have 50 TEdits on a form. Thus the loop to enable them and I need to clear the text property.
Code: Pascal
[Select]
[+]
[-]
for
i
:
=
0
to
ComponentCount
-
1
do
if
Components
[
i
]
is TControl
then
begin
TControl
(
Components
[
i
]
)
.
Enabled
:
=
True
;
TControl
(
Components
[
i
]
)
.
text
:
=
''
;
{ <===Error}
end
;
end
;
Thanks

It didn't work as expected.
Attached the program. It's a very small demo.

Form in demo project was not visible for me. My screen was to small.
Changed the Form Left and Form Top to 0 in lfm file. After that the form was visible.
I changed the procedure below in your project. That worked without errors or problems.
Code: Pascal
[Select]
[+]
[-]
procedure
TForm1
.
ControlClearCB
;
var
i
:
Integer
;
begin
for
i
:
=
0
to
ComponentCount
-
1
do
if
Components
[
i
]
is TEdit
then
begin
TEdit
(
Components
[
i
]
)
.
text
:
=
''
;
end
