VB.NET and BITS - Background Intelligent Transfer Service

Question

Has any one used BITs in VB.NET? If so, do you have code samples and advice?

I was looking at SharpBits but I have a VB project that I wanted to use BITS for. Is it possible to use it with my VB.NET program? (.NET 2.0) I was tempted to try to convert each class to VB.NET in the SharpBits.Base folder but figured I'd ask in case someone has headed down this route before.

Edit: Ok folks in case you run across this question. What you can do is in the Sharpbits.Base folder (that you download from codeplex) there is a DLL you can reference in the Bin directory. You can add that into your references to access it. Marking Konrad as answer since he was kind enough to post.

Further edit:
I managed to get sharpbits working with some quick code which I pasted below for anyone who might stumble upon this question. Like I mentioned above add the DLL to your project.

Dim b As New SharpBits.Base.BitsManager
Dim mynewjob As SharpBits.Base.BitsJob = _ 
b.CreateJob("jobname", SharpBits.Base.JobType.Download)
mynewjob.AddFile("\\server\share\bigfile.zip", "c:\bigfile.zip")
mynewjob.Resume()

You'll need to write some logic to check for the status of the job. Once it hits "Transferred" status you can then mark it as complete. This will write the file from a .bin to the file name you listed. Something that helped me was installing the Windows Support Tools (you can get it from a Windows 2003 Cd/DVD in the sup tools folder)and using Bitsadmin.exe to view the status of the job while debugging. Hope this helps the next rookie. =)

Answer 1

Any reason why you can't simply use SharpBits in VB? The advantage of .NET is precisely that libraries written in the different .NET languages can interoperate seamlessly so you can simply use SharpBits in VB, no matter what .NET-compliant language it was written in.

Answer 2

You could take a look here:

Using Windows XP Background Intelligent Transfer Service (BITS) with Visual Studio .NET

I have started from here to write my own library to manage BITS to transfer big video file across private LAN. Example are for NET 1.1 but should not be difficult port it to NET 2.0.

Answer 3

Here's a new alternative. The BITS team at Microsoft now has a page on Calling into BITS from .NET and C# using reference DLLs plus a complete sample call BITS Manager on GitHub.

I've just tried using them with Visual Basic; my code ended up looking like this:

    Imports BITS = BITSReference1_5
    Module Module1
        Sub Main()
            Dim mgr = New BITS.BackgroundCopyManager1_5
            Dim jobGuid As BITS.GUID
            Dim job As BITS.IBackgroundCopyJob
            mgr.CreateJob("My simple job", BITS.BG_JOB_TYPE.BG_JOB_TYPE_DOWNLOAD, jobGuid, job)
            job.AddFile("http://www.microsoft.com", "c:\temp\2019\BITS-VB\Downloadfile.html")
            job.Resume()
        End Sub
    End Module

(Note that I also added a reference to a DLL that I downloaded from the BITS Manager source from the Reference DLL directory)
