Dear Support,
if you use the demo MultiView Performance Demo
- DiskCache ON
- Thumbnail
- Thread Loading Count > 0
- Root Directory is Documents or Picture (This is the bug)
then the thumbs will not create correct.
You can see there is all the same thumb.

We use v11.4.0
I check whether our subscription is valid. |

Sorry, can you confirm what version of ImageEn you are using? We improved this in 11.4.5.

Ok the subject of my thread is wrong.
I go deeper to source to search the reason why the diskcache is not working in my project.
at the end of my afternoon, i extract the little piece of source from iemview.pas from the
function _GenerateHashName.
There is a hash function from stream. Please ignore the Memo.
var
hs: TIEHashStream;
s: String;
Index: integer;
begin
for Index := 0 to cxMemo1.Lines.Count - 1 do
begin
s := cxMemo1.Lines[Index];
hs := TIEHashStream.Create(iehaSHA);
hs.Write( s[1], length(s) );
cxMemo2.Lines.Add('~ie' + String(hs.GetHash()));
hs.Free();
end;
end;
s is the debug value from _GenerateHashName

The result
~ie8872390ef8f5a0c18d39443dd85505fb3ebf6397
~ie8872390ef8f5a0c18d39443dd85505fb3ebf6397

~ie8872390ef8f5a0c18d39443dd85505fb3ebf6397
Oh no, the hash is not unique.
Now, change the type of s to AnsiString and let it run.

Hey, its unique. I think there is a problem in the hash function. |

Hi
Please look in the \~ie\ folder of your temp folder (IEGlobalSettings().TempPath). Do the disk cache filenames look valid? I.e.g something like: ~ie1be161519ad789e9c6b7c591526611524607eda4
Also, email me to test an update.

I use the Version 11.4.0 and the Demo is recompiled with this version.
I have also the cache problem in my program.
I think there is a problem with windows user standard folders.
If i select a directory with an absolute path there is no problem.
But the PICTURES directory has many variants
C:\Users\<user>\Pictures
C:\Benutzer\<user>\Pictures
C:\Benutzer\<user>\Bilder
and so on.

Hi
I cannot reproduce that, but the disk cache filename is hashed so it can be insufficiently random. Some changes were made to this recently. Are you using the latest version of ImageEn and/or the current version of the Performance demo?
