I have an idea for pausing downloads

Recommended Posts

We would have to first enable SeRestorePriviledge for the process, then identify the thread performing the download, then invoke SuspendThread, and finally ResumeThread

Something like the following..but I have no idea how to actually use DllCall...just reading documentation

DllCall("kernel32.dll","int","SuspendThread","str",$thread)

I used SysInternals Process Explorer to suspend my download program, and on resume it also resumed the download. I can also kill threads individually with it. For example, I can kill the thread producing the GUI (see the Scripts and Scraps forum) and the process will stay alive and continue downloading the file in the background. They must be using the methods mentioned above. I was able to get the following information about the thread. maybe it will help.

It looks like coding InetGet must have been fun.

It might work, but I think the odds are better that the connection will die resulting in an incomplete transfer. I also think that it's almost totally useless. Even if it did work, pausing a thread and resuming during the same session doesn't seem all that useful. Pausing/Resuming across sessions is something that would be uesful, but that's not possible with the current implementation.
