corrupt files

[Mark Williams]

Hi Kevin,

Apologies but I still have not had time to try out licensed version of Pro to see what is causing conflict.

In meantime, however, I have a problem with Lite.

I am using it to back up some development files from a list to a CD. Many of the files backup ok, but others fail.

Winzip sys that there is "invalid compressed data to inflate" and your own demo app fails tehm for bad password. They are all given the same password on zipping.

I've set out below the properties that I have applied to vclZip and the snipped ot code that deal with compression. Could you please have a look at this and tell me what you see as the problem. Thanks. BTW, the files are also not compressed at all even though they are text files. Any idea why?

Regards

Mark

VCLZIP properties:

object VCLZip1: TVCLZip
OnStartZipInfo = VCLZip1StartZipInfo
OnEndZip = VCLZip1EndZip
OnZipComplete = VCLZip1ZipComplete
end

(I haven't included the code for the various vclzip events as it relates pretty much to progress info and I can't see how it would affect zipping).

Code used
for i:=0 to ListBox1.items.Count-1 do
vclZip1.FilesList.Add(ListBox1.items[(i]);

With VCLZip1 do
begin
EncryptBeforeCompress:=true;
Password:='password';
StorePaths := True;
PackLevel := 6;
zip;
end;

Off hand I can't say why you are having this problem. Let me play around a bit and see if I can re-create it.
