Can't Save memory Stream to files

[ad]

I use a ClientDataSet to create a dataset in memorystrem
I want to zip the memorystrem and save it to disk.
But after ececuting the below code, I can not find the zipped file.

How can I do ?

ClientDataSet1.SaveToStream(aMemoryStream);
VCLZip.ZipFromStream(aMemoryStream, 'c:\ttt.zip');

Somewhere you should set the VCLZip.ZipName property before calling Zip. That will determine where the zip file is located.

Also, I'm not sure, but you might want to set aMemoryStream.Position := 0 before calling ZipFromStream.
