Good Evening Everyone:

Code: Pascal
[Select]
[+]
[-]

Condidat
=
record
nom
,
prenom
:
string
[
20
]
;
decision
:
1
..
3
;
end
;
con
=
File
of
Condidat
;
var
coni
:
con
;
cona
:
TextFile
;
procedure
rangerajour
(
var
c
:
con
;
var
ca
:
TEXT
)
;
var
x
:
Condidat
;
txt
:
string
[
255
]
;
begin
reset
(
c
)
;
{$I-}
Rewrite
(
ca
)
;
{$I+}
while
not
(
EOF
(
c
)
)
do
begin
read
(
c
,
x
)
;
with
x
do
begin
if
decision
=
2
then
begin
try
if
IOResult
=
0
then
begin
// OK, we can write the file
txt
:
=
'Nom: '
+
nom
+
' , Prenom: '
+
prenom
;
writeln
(
txt
)
;
write
(
ca
,
txt
)
;
end
else
begin
Writeln
(
'error opening file for writing'
)
;
end
;
finally
writeln
(
'Problem Occured'
)
;
end
;
end
;
end
;
end
;
end
;
begin
assign
(
coni
,
'D:\bac\resultat.FCH'
)
;
AssignFile
(
cona
,
'D:\bac\ajour.txt'
)
;
//remplir(coni);
admis
(

(
coni
,

Object Pascal programmers should get rid of their "component fetish" especially with the non-visuals.

Problem Solved The issue is that i forgot to close the file when i finished writing the lines onto it.
Code: Pascal
[Select]
[+]
[-]
procedure
rangerajour
(
var
c
:
con
;
var
ca
:
TextFile
)
;
var
x
:
Condidat
;
txt
:
string
[
255
]
;
begin
reset
(
c
)
;
{$I-}
rewrite
(
ca
)
;
{$I+}
while
not
(
EOF
(
c
)
)
do
begin
read
(
c
,
x
)
;
with
x
do
begin
if
decision
=
2
then
begin
if
IOResult
=
0
then
begin
// OK, we can write the file
txt
:
=
'Nom: '
+
nom
+
' , Prenom: '
+
prenom
;
//writeln(txt);
writeLn
(
ca
,
txt
)
;
end
else
begin
Writeln
(
'error opening file for writing'
)
;
end
;
end
;
end
;
end
;
//i added this line and it is working fine now
close
