[...] hope you enjoyed the first part of the introduction to BITS. In this second part, we want to improve our job list (a little bit) [...]

Thank you for sharing the article. I also hope the author does write a new article with :

- how to actually download something (lan shares / ftp / http)
- how to host the downloads (lan shares / ftp / http)

Thank you Sebastian for this improvement. It was new to me.

For all others: Include “ComObj” into your uses clause in order to get this feature working. Doing it the way, Sebastian mentioned, above you can omit the two lines “CoInitializeEx” and “CoUninitialize”.

I’ll try to correct the listings.

CoUnitialize should only be called when CoInitializeEx succeeded. Otherwise the call to CoUnitialize will shut down com too early. Use CoInitFlags in the initialization section, and Delphi will take care of it.

initialization
CoInitFlags := COINIT_APARTMENTTHREADED;
end.

Thanks for the reply Ajasja.

I’m thinking about the continuation and you are right: starting own downloads is much more interesting.

Thank you. The code is fixed. I also added:

“Notice:
The code examples above do not use these new units, however. Thus you can just include JwaBits.pas (or JwaWindows).”

I hope the author does write a new article

There’s a small error:
an end of line is missing on line 14
//maybe the right is missing … try to get just our jobs if not Succeeded(Res) then
should be
//maybe the right is missing … try to get just our jobs
if not Succeeded(Res) then

Otherwise keep up the good work.
Maybe for part two: how to actually download something and how to host the downloads?:)

Best regards,
Ajasja
