Reopened Issue: Compatibility issues with x64 systems [7046]

xidar — Fri, 14 Jun 2013 07:15:51 GMT

Utils.cs GetBitsVersion() method fails on x64 systems, but as responses show there might be several more x64 traps around in the code. Solution is to force the system to run in 32bit mode. In Visual Studio set Project + Properties, Build tab, Platform Target = x86.
More details on the issue is on StackOverflow:

At changesets 65477 and 65478, the projects were upgraded to Visual Studio 2010 and the versions were bumped from 2.0 and 3.5 to 4.0.

The problem with that is a project that must target, say, .NET version 3.5 (for legacy reasons) can not reference SharpBITS.Base.dll. It is possible to develop and compile with Visual Studio 2010 and the newest C# compiler and related tools, but still target an older framework version.

This can be as simple as changing the following line in SharpBITS.Base.csproj (I picked version 3.5 to be consistent with my example):
@@ -22,7 +22,7 @@
<UpgradeBackupLocation>
</UpgradeBackupLocation>
<OldToolsVersion>3.5</OldToolsVersion>
- <TargetFrameworkVersion>v4.0</TargetFrameworkVersion>
+ <TargetFrameworkVersion>v3.5</TargetFrameworkVersion>
<PublishUrl>publish\</PublishUrl>
<Install>true</Install>
<InstallFrom>Disk</InstallFrom>

...or can be done from within Visual Studio itself by a right-click on the project > Properties > Application > Target framework.

Alternately, you could do what James does with his Newtonsoft.Json NuGet package and bundle assemblies targeting multiple frameworks at once, but that's more work. :)

Thanks!

giovanni_enrico — Fri, 03 May 2013 07:59:49 GMT

Hi

if you want to know the job status using the job id you can ask it to the BitsManager object like in the snippet below

BitsManager manager = new BitsManager();
BitsJob job = manager.CreateJob("Downloader", JobType.Download);
job.AddFile(fromFile, toURL);
// get job id
Guid jobId = job.JobId;

// retrieve the job from manager
BitsJob currentJob  = manager.Jobs[jobId];
JobState jobState = currentJob.State;

SreeRama87 — Thu, 02 May 2013 17:07:59 GMT

Dear Team,

I'm successfully uploading file onto server using BITS , while sending each file onto server i'm able to check for the Job Status and perform my actions accordingly.

Please let me know how to get Job Status using GUID/Job Name? . I have to check using GUID because i'm storing it for polling purpose, so that I can check the Status later and Handle events accordingly?

Here is my code.

try
        {
            string[] files = null;
            BitsJobs MultipleJobs = null;


            string Path1 = @"C:\Upload1";
            if (Directory.Exists(Path1))
            {
                files = Directory.GetFiles(Path1);
            }


            if (files.Count() > 1)
            {


            }


            int x = files.Count();


            String[,] myArray3 = new string[x, x];

            Collection<BitsFileInfo> obj1 = new Collection<BitsFileInfo>();
            int i = 0;
            for (i = 0; i <= files.GetUpperBound(0)  i++)
            {

                DateTime DATE = System.DateTime.Now;

                JobType jtx = JobType.Upload;
                BitsManager BitsManager1 = new BitsManager();
                BitsJob bjobs;

                string JobName = DATE.ToString("ddMMyyyyhhmmssfff");

                bjobs = BitsManager1.CreateJob(JobName,  jtx);

New Post: SharpBits - Error: The requested URL does not exist on the server

shoaibsuleman — Fri, 05 Apr 2013 11:46:08 GMT

Hi

I am using your sample code for testing so I can create my own utility to transfer the file manually from our data server. Server is credentials protected and I am using HTTPS in the url.

When I run the code I get the errors:
1) Error description: The requested URL does not exist on the server
2) Error context: Remote file
Error context description: The error occurred while the remote file was being processed.
3) Error protocol: Https

Could you please help me understanding those error and what would be the root cause. I can access the Https url in the browser with the same credentials I've hard coded into the app.

Thanks

Commented Issue: The RPC Server is Unavailable [12848]

jmalinovskis — Wed, 06 Mar 2013 11:39:59 GMT

Win Server 2008 R2 64bit + implemented as Windows service (already updated to latest SharpBITS library).

This error occurs randomly - once in couple days. It makes all other calls to BITS manager object to fail => and windows service stops due BITS error event started. I did one workaround - wrapped call to the list Queue method with "try .. catch" and recreate BITS manager object "on error". But this hack-style solution only little bit improved stability - now service suddenly stops working without any error about once in a week. :(

(Same code worked perfectly on Win Server 2003.)

bcanon — Wed, 06 Feb 2013 14:49:12 GMT

Looks like issue in BITS 4.0 when trying to pass allusers for enum for this job. I think Microsoft changed the security protocol from reading their documentation. A virtual login doesn't give you the access you need to view another users BITS jobs from my basic understanding.

These sources are compiled to a native dll. This dll is then referenced from my managed code and I call the dll from my managed code like in this snippet:

[DllImport("bitshttpheader.dll", CallingConvention = CallingConvention.Cdecl)]
private static extern void setCustomHeaders(Guid guid, [MarshalAs(UnmanagedType.LPWStr)] string pwszHeader);

// snipp some code here.......

            BitsManager manager = new BitsManager();
            manager.EnumJobs(JobOwner.CurrentUser);
            manager.OnJobTransferred += new EventHandler<NotificationEventArgs>(manager_OnJobTransferred);
            manager.OnJobError += new EventHandler<ErrorNotificationEventArgs>(manager_OnJobError);

            BitsJob newJob = manager.CreateJob("TestJob", JobType.UploadReply);
            newJob.AddFile(UploadDesitination + "x.txt", "C:\\x.txt");
            Guid guid = newJob.JobId;

            setCustomHeaders(guid, "MyHeader_2: Header Two Value\r\n");
            newJob.Resume();

This code is just a working prove of concept for me and I'm still searching for a 'cleaner' solution.

New Post: IBackgroundCopyJobHttpOptions

mldisibio — Tue, 22 Jan 2013 15:44:37 GMT

So I put this code inside my BackgroundCopyJob implementation as the managed version of your snippet above:

public IBackgroundCopyJobHttpOptions HttpOptions
{
	get
	{
		Guid interfaceGuid = typeof(IBackgroundCopyJobHttpOptions).GUID;
		IntPtr jobPtr = Marshal.GetIUnknownForObject(this.interopJob);
		IntPtr httpOptionsPtr;
		Marshal.QueryInterface(jobPtr, ref interfaceGuid, out httpOptionsPtr);
		return Marshal.GetObjectForIUnknown(httpOptionsPtr) as IBackgroundCopyJobHttpOptions;
	}
}

It comes back with a non-null object, and if I query, say, 'httpOptions.GetSecurityFlags(out secFlags)' I get a uint or ulong of zero. But I stil get the AccessViolation if I try to set them.

Can you post an example of how you call your unmanaged code snippet from managed?

Also, I am not an expert in COM Interop, but based on the other signature translations and what I have read about how an umanaged ulong is really only four bytes, I was thinking the interface definition you proposed ought to be

void SetSecurityFlags([In] uint Flags);
void GetSecurityFlags(out uint Flags);

sounds like there is some need for improvement. I'll have those fixed incorporated in the source and publish an updated version.

New Post: IBackgroundCopyJobHttpOptions

schmid03 — Mon, 21 Jan 2013 07:32:23 GMT

As far as I know the cast is the same as

  IBackgroundCopyJob* pJob = NULL;
  IBackgroundCopyJobHttpOptions* pHttpOptions = NULL;

  hr = pJob->QueryInterface(__uuidof(IBackgroundCopyJobHttpOptions), (void**)&pHttpOptions);

I use this code snippet in an extra .dll which I call from my managed code and then it's possible to set the custom header in pHttpOptions without any problems.

http://msdn.microsoft.com/en-us/library/windows/desktop/aa964250(v=vs.85).aspx says to call the IBackgroundCopyJob::QueryInterface method with the HttpOptions guid...but I do not see that method defined anywhere...

I would suspect that casting a job to the IBackgroundCopyJobHttpOptions is not the correct way to get a handle to the options...but I don't have a solution yet either...

mldisibio — Fri, 18 Jan 2013 20:34:52 GMT

Just wanted to confirm that I had the same exact problem and fixed it by correcting the Guid.

Also, schmid03 is correct that checking the qmgr.dll version does not work correctly on Windows Server 2008 R2 and possible other versions of Windows. In some cases, I believe the dll even has a different name. Based on some old code found in the msdn forums back in the days of version 1.5, I created the following way to check:

readonly BitsVersion _version = BITSWrapper.BitsVersion.Bits0_0;
try
{
	this.interopManager = new BackgroundCopyManager30() as IBackgroundCopyManager;
	if(this.interopManager != null)
		_version = BITSWrapper.BitsVersion.Bits3_0;
	else
		throw new NotSupportedException();
}
catch
{
	try
	{
		this.interopManager = new BackgroundCopyManager20() as IBackgroundCopyManager;
		if(this.interopManager != null)
			_version = BITSWrapper.BitsVersion.Bits2_0;
		else
			throw new NotSupportedException();
	}
	catch
	{
		try
		{
			this.interopManager = new BackgroundCopyManager15() as IBackgroundCopyManager;
			if(this.interopManager != null)
				_version = BITSWrapper.BitsVersion.Bits1_5;
			else
				throw new NotSupportedException();
		}
		catch
		{
			try
			{
				this.interopManager = new BackgroundCopyManager10() as IBackgroundCopyManager;
				if(this.interopManager != null)
					_version = BITSWrapper.BitsVersion.Bits1_0;
				else
					throw new NotSupportedException();
			}
			catch
			{
				throw new NotSupportedException("The required 'Background Intelligent Transfer Service' library does not appear to be installed on this machine.");
			}
		}
	}
}
