Hi Serge,

I'm writing a new “picture-showing” module to my program and whenever I choose a new directory and try to clear the pictures loaded previously into the ImageList,

it's NOT clearing them. (Took me 3 days for searching 3000 lines of my programcode until realized the error is in AC 🙁 ) I've tried everything now…

Maybe it's important: – there is 1 TsVirtualImageList attached to it too!

1. When I have tried this way:

Code:

ikon_Lista.Clear;

nothing happened.

Code:

(ikon_Lista.Count = 0; BUT ikonLista.Items.Count= stayed 407)

2.

Code:

for d := ikon_Lista.Count-1 downto 0 do
ikon_Lista.Delete(d);

This way > deleting 1 item from 407 took ca. 5 seconds !!! (All together more minutes)

… so I've enclosed it between AcBegin/endUpdate , and that solved the slowness.

Code:

vIkonLista.AcBeginUpdate;
ikon_Lista.AcBeginUpdate;

vIkonLista.ClearItems; // <- I have to clear cache from virtualList myself too ... I guess
for d := ikon_Lista.Count-1 downto 0 do
ikon_Lista.Delete(d);
ikon_Lista.Clear;

vIkonLista.AcEndUpdate(False);
ikon_Lista.AcEndUpdate(False);

But still not working 🙁 … keeping all pictures

Please FIX IT quickly ! Thank you 😉

PS: Originally I've compiled with old, stable version (2013 v8.42 b594) … so I've just upgraded to newest beta (2014 v9.03 b690) but no change.

Hi again,

I've just found an other error:

Tried to recompile the “VirtualImageList DEMO” you've sent me in 2012.dec. with the newest component pack …

and the .dfm file suddenly increased from 2927 Kbyte > to 9461 Kbyte. Also the compiled EXE increased 3x bigger.

Looked into it, and realized it saves a HUGE BMP file :

Code:

…
object sVirtualImageList1: TsVirtualImageList
Height = 128
Width = 128
AlphaImageList = sAlphaImageList1
UseCache = False
Left = 368
Top = 136
Bitmap = {
494C010128002C00040080008000FFFFFFFF2100FFFFFFFFFFFFFFFF424D3600
