If you want to program with Microsoft’s Background Intelligent Transfer Service (BITS) then you will need the TLB or header files. These can be generated from the IDL files that come with the Windows XP SP2 Platform SDK, or any of the subsequent platform SDKs, the latest being Windows SDK for Windows Server 2008 and .NET Framework 3.5. You will need MIDL to generate the needed files. It is rather a pain to download that whole SDK and then generate the useful files.To make your life easier I have generated the useful files, and also ran them through Delphi RAD Studio 2007 for Win32 to create Object Pascal wrappers for your Delphi programming pleasure. Then I wrapped it all up in a zip for easy downloading. Much quicker to download.

As a note, you do not need to deploy any of these files, or the files in the SDK with your application. You just need to ensure that the Background Transfer Service is running on the target machine.

For more information, I have created a hub page on Advanced Downloads with Delphi that I will update with more information as I gather it.

Enjoy!

BITS is Microsoft’s Background Intelligent Download Service. It was added in XP to allow downloading of security patches in the background. In the Platform SDK Microsoft provided a COM interface to allow developers to work with BITS. Unfortunately it is a bit of a pain to actually get to the interface, especially if you are not using Visual Studio. To make it easier for Delphi developers to work with BITS, I am providing my imported Type Library for the BackgroundCopyManager.

Alternatively you can use the JEDI Win32 API Library available on Sourceforge. It has the Bits interface (version 1.5) split into a few different files (JwaBits1_5.pas, JwaBits.pas, JwaBitscfg.pas, and JwaBitsMsg.pas [although they reference other included files]) and cleaned up a little bit. In addition it includes a number of other useful Delphi wrappers for Win32 API’s. I recommend this library over the raw TLB import. My demo will work with either one.

UPDATE: I recreated the demo and added it to the archive!
