Is there a way to have this download more than one file on this screen? :huh

[Tek]

You should be able to use any of the 'Download Multiple Files' screens already built into TU2 to accomplish this.

just a simple question, im using this download and i love it but is it possible where the path is to store it to have it so it download to the current location of the setup ???? i hope someone knows what i mean.

[Eagle]

the Lua builtin variable _SourceFolder will return the full Folder path to mysetup.exe.

find the action in the download script that sets the destination path
and change it to for eg: _SourceFolder.."\\mydest.ext"

or _TempLaunchFolder.."\\.... will dload to where irsetup.exe is running.

HTH

..another thing to consider when dloading to dests is to perform a
drive.getfreespace check

look it up in actions ..you can use the dest folder full path if ya like.

[cyberops]

[Eagle]

I think that I found a bug, the actions in "on finish" also happen when the download is canceled.

[Shivansps]

and, there is any way to download the file to %AppFolder%//*?

[jassing]

and, there is any way to download the file to %AppFolder%//*?

In the OnStart
change
strDestinationFile = _TempFolder.."\\myfile.zip";

to reflect any folder you want!

strDestinationFile = SessionVar.Expand("%AppFolder%\\myfile.zip");

[Shivansps]

oh, thanxs.

I just noticed if the file was already download before and their are at the "strDestinationFile", when the programs starts to download it again their just override the fully downloaded file by the "downloading one", who is incomplete.

There is any way to avoid this?, maybe disable the override or something, or a warning or something that gives you a chance to abort the download before the file be deleted.

Go ahead and check if the file is there -- if it is; don't do the do the actual download -- or better yet; offer a dialog to say "it's there; would you like to re-download?" and then delete the file prior to starting the download.
