Date of last Version

What do you mean by "last version"? You mean the installed version? You could store/read a value from somewhere on your computer.

I Mean the last version on ther server.I would like to get the date of release for the version. Not the date of download by the user.

Well, if you want to show this information in wyUpdate, then just put the date in the changes textbox. If you want to get this information from within your app, then just query the wyserver.wys file from your server to get the date the file was modified.

Thanks !
