[INFO] Use TRegistry to get list of installed programs on Windows 32/64-bit

The attached example is my attempt to consolidate the information from this post and others:
https://forum.lazarus.freepascal.org/index.php/topic,33990.15.html
I'm hoping this will help others use TRegistry to get the list of installed programs on Windows.
Tested using Virtualbox on WinXP, Win7, and Win10 - both 32 and 64-bit
My Config:
Windows 10 Home 64-bit
Lazarus 1.8.2 with FPC 3.0.4 64 bit, and cross-i386-win32-win64

Thanks for sharing. But you should call BeginUpdate/EndUpdate to avoid scrolling the memo while adding lines:
Code: Pascal
[Select]
[+]
[-]
procedure
TfrmMain
.
ShowList
(
aTitle
:
string
;
aList
:
TStringList
)
;
var
i
:
integer
;
begin
aList
.
sort
;
Memo
.
Lines
.
BeginUpdate
;
// <-- inhibits repainting of Memo
try
Memo
.
Append
(
aTitle
)
;
for
i
:
=
0
to
aList
.
Count
-
1
do
begin
Memo
.
Append
(
Format
(
'%4d: %s'
,
[
i
+
1
,
aList
[
i
]
]
)
)
;
end
;
finally
Memo
.
Lines
.
EndUpdate
;
// <-- activates repainting of Memo again.
end
;
end
;

Thank you, wp!
I have used Memo.Enabled:=true/false on other projects.
I like your suggestion much better.
I learned something new today.
