Hello,
when i use ImageEnFolderMView and IncludeSubFolders = true, and
IEFolderMView1.Folder := C:\ or D:\ (so Root), the Programm hanging on.
Your Example FolderMView has the same Effect.
What kann i do, for searching over the komplett Device ?

Hi Nigel,
thanks, it works perfectly like this, I can cancel now the process.
Unfortunately it is not possible to scan a complete hard disk c:\ or e:\,
it just takes too long.
Unfortunately, there is no message in between, so that you cannot see whether the action is still active.

Hi Klaus
Yes, there doesn't seem to be a practical way around that. Perhaps we need a maximum number of folders. I will investigate that.

Hallo Nigel,
why is the value per in IEFolderMView1IOProgress(Sender: TObject; per: Integer);
never > 0 ?
And what is the difference to
IEFolderMView1DrawProgress(Sender: TObject; per: Integer);

Hi Klaus
It is zero while filling the content with sub-folders because the total number of folders is not known. Progress is called only to allow the process to be aborted.
OnDrawProgress occurs as each image is painted.
per returns the number of images completed (painted or skipped because they are off-screen) out of the total number of images in the control. It will reach 100% when all images onscreen have been painted.

Hi Klaus
We have now implemented a SubFolderLimit property that prevents too many folders from being parsed. It is also used to return a more accurate progress percentage. You can email me to test it.

Also, please note that is is OnProgress that should be used during fill operations, not OnIOProgress.
