You close the file.... If you want to append, use a TFilestream.

Specialize a type, not a var.

procedure

.
SendClick
(
Sender
:
TObject
)
;
var
sl
:
TStringList
;
filename
:
String
;
function
GetFileName
:
string
;
const
TextFilePath
=
'\\SERVICEII-PC\print\sram\'
;
begin
Exit
(
TextFilePath
+
ComboBox2
.
Text
+
'.txt'
)
;
end
;
begin
filename
:
=
GetFilename
;
if
not
FileExists
(
filename
)
then
Exit
;
sl
:
=
TStringList
.
Create
;
try
sl
.
LoadFromFile
(
filename
)
;
sl
.
AddStrings
(
Memo2

sl
