the following code connects to a remote pc and execute the process try.exe located on that pc.
string prcToRun = "\"C:\\try.exe\" \"";;
object[] theProcessToRun = { prcToRun };
ConnectionOptions theConnection = new ConnectionOptions();
theConnection.Username = "domain\\user";
theConnection.Password = "password.";
ManagementScope theScope = new ManagementScope("\\\\192.168.1.1\\root\\cimv2", theConnection);
ManagementClass theClass = new ManagementClass(theScope, new ManagementPath("Win32_Process"), new ObjectGetOptions());
theScope.Connect();
theClass.InvokeMethod("Create", theProcessToRun);
It works fine, because "try.exe" does what I expect. However I'd like to obtain back the result of try.exe execution. Is it possibile with wmi? At least I need to know when try.exe ends, but it would be better return a value. I know it would be possibile with psexec, but I can't use it.
Thank you

I am trying to use the TFS API to rollback a changeset.
I tried using all Workspace.Rollback methods but the action does nothing (The GetStatus returned says NoActionNeeded:true).
Has anyone managed to get this to work and can send a working code sample?
From the documentation of the method:
public GetStatus Rollback(
string[] paths,
RecursionType recursion,
VersionSpec itemSpecVersion,
VersionSpec versionFrom,
VersionSpec versionTo,
LockLevel lockLevel,
RollbackOptions options,
string[] itemAttributeFilters
)
I do not understand what the parameter VersionSpec itemSpecVersion means.
It says 'The version spec that identifies the item to which the user is referring.' but then how does it differ from the parameter versionFrom?
What should I pass as the itemAttributeFilters (the last paramter)?
You can rollback changeset programmatically with the following code:
TfsTeamProjectCollection tpc = TfsTeamProjectCollectionFactory.GetTeamProjectCollection(new Uri("tfsCollectionURL"));
VersionControlServer vcs = (VersionControlServer)tpc.GetService(typeof(VersionControlServer));
string workingDirectory = #"localPath";
string[] workigDnirectoryArr = new string[] { workingDirectory };
Workspace ws = vcs.GetWorkspace("$/serverPath");
int fromCS = 456; //changesetid
int toCS = 495; //changesetid
VersionSpec versionSpecFrom = new ChangesetVersionSpec(fromCS);
VersionSpec versionSpecTo = new ChangesetVersionSpec(toCS);
var status = ws.Rollback(workigDnirectoryArr, RecursionType.None,null, versionSpecFrom, versionSpecTo,LockLevel.None,RollbackOptions.None,null);
I know how to get the serial number of a mac computer using objective c but wondered if there was a way using c# (mono)?
Obviously this is to uniquely identify a machine. I am already using the MAC address but need something which can't be spoofed.
THe following should give you the serial number. Though it is not purely via mono. But this should work.
string serialNumber;
using (var p = new Process())
{
var serialRegex = new Regex("\"IOPlatformSerialNumber\" = \"(\\S+)\"");
p.StartInfo = new ProcessStartInfo("/usr/sbin/ioreg",
"-c IOPlatformExpertDevice");
p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardOutput = true;
p.Start();
serialNumber = serialRegex.Match(p.StandardOutput.ReadToEnd()).Groups[1].Captures[0].Value;
p.WaitForExit();
}
I'm trying to use the SqlFileStream object in a WCF service to get a handle to a specific file that is in a SQL Server 2012 FileTable. I'm able to get the path and transaction context like you would expect with no issues using this piece of code:
using (SqlConnection con2 = new SqlConnection(ConfigurationManager.ConnectionStrings["FileStorage"].ConnectionString))
{
con2.Open();
string getFileHandleQuery = String.Format(
#"SELECT FileTableRootPath(), file_stream.GetFileNamespacePath(), GET_FILESTREAM_TRANSACTION_CONTEXT()
FROM {0}
WHERE stream_id = #streamId", "FSStore");
byte[] serverTransactionContext;
string serverPath;
using (SqlCommand sqlCommand = new SqlCommand(getFileHandleQuery, con2))
{
sqlCommand.Parameters.Add("#streamId", SqlDbType.UniqueIdentifier).Value = new Guid(finalFileHandleStreamId);
using (SqlDataReader sqlDataReader = sqlCommand.ExecuteReader())
{
sqlDataReader.Read();
serverPath = String.Concat(sqlDataReader.GetSqlString(0).Value, sqlDataReader.GetSqlString(1).Value);
serverTransactionContext = sqlDataReader.GetSqlBinary(2).Value;
sqlDataReader.Close();
}
}
con2.Close();
}
However, once I try and actually use the path and transaction context to create a new SqlFileStream:
using (SqlFileStream dest =
new SqlFileStream(serverPath, serverTxn, FileAccess.Write))
{
...
}
The above blows ups with the following exception: The mounted file system does not support extended attributes.
Can someone please explain to me what I'm doing wrong here?
Thanks!
If you are trying to use FileTable and receive an error when new a SqlFileStream object, please check the filePath value.
SqlFileStream sfs = new SqlFileStream(filePath, objContext, System.IO.FileAccess.Read); <-- Error "The mounted file system does not support extended attributes"
Correct way to obtain the filePath value is
SELECT [file_stream].PathName() FROM dbo.fTable WHERE name = 'test.xlsx'
filePath value should look like:
\\HOSTNAME\MSSQLSERVER\v02-A60EC2F8-2B24-11DF-9CC3-AF2E56D89593\test\dbo\fTable\file_stream\A654465D-1D9F-E311-B680-00155D98CA00\VolumeHint-HarddiskVolume1
not like:
\\HOSTNAME\MSSQLSERVER\Store\fDirectory\test.xlsx
That is required by design. Please refer to

Access FILESTREAM Data with OpenSqlFilestream

I'm running MDS on a virtual machine and trying to access the service from my host OS.
I've been able to add something to the database but my data is all over the place and in the Master Data Manager (website) I don't see the new member.
I suppose I shouldn't be using Attributes but something else but what and how? Are there tutorials because I can't find any ...?
Here's the code I'm using:
International international = new International();
EntityMembers entityMembers = new EntityMembers();
// Set the modelId, versionId, and entityId.
entityMembers.ModelId = new Identifier { Name = modelName };
entityMembers.VersionId = new Identifier { Name = versionName };
entityMembers.EntityId = new Identifier { Name = entityName };
entityMembers.MemberType = memberType;
Collection<Member> members = new Collection<Member>();
Member aNewMember = new Member();
aNewMember.MemberId = new MemberIdentifier() { Name = employee.FullName, Code = aNewCode, MemberType = memberType };
Collection<MDS.Attribute> attributes = new Collection<MDS.Attribute>();
MDS.Attribute attrOrgUnit = new MDS.Attribute();
attrOrgUnit.Identifier = new Identifier() { Name = "OrganizationalUnit" };
attrOrgUnit.Value = employee.OrganizationalUnit;
attrOrgUnit.Type = AttributeValueType.String;
attributes.Add(attrOrgUnit);
aNewMember.Attributes = attributes.ToArray();
members.Add(aNewMember);
entityMembers.Members = members.ToArray();
// Create a new entity member
OperationResult operationResult = new OperationResult();
clientProxy.EntityMembersCreate(international, entityMembers, false, out operationResult);
HandleOperationErrors(operationResult);
I have been able to fix my own problem.
First of all: creating separate variables with collections and converting them to arrays afterwards is not necessary. The code from the tutorials works but fails to mention that, when adding the service reference, you have to configure it (right-click on the service reference -> configure) to use Collections as "Collection type" instead of arrays and to generate message contracts.
Second, the code above with the attributes is correct and works perfectly. The problem I had which failed to add messages with attributes was unrelated. It was a connection/authentication problem between my Host OS and Guest OS.
Hope this helps someone.
I am learning to use the Rx extensions for a Silverlight 4 app I am working on. I created a sample app to nail down the process and I cannot get it to return anything.
Here is the main code:
private IObservable<Location> GetGPSCoordinates(string Address1)
{
var gsc = new GeocodeServiceClient("BasicHttpBinding_IGeocodeService") as IGeocodeService;
Location returnLocation = new Location();
GeocodeResponse gcResp = new GeocodeResponse();
GeocodeRequest gcr = new GeocodeRequest();
gcr.Credentials = new Credentials();
gcr.Credentials.ApplicationId = APP_ID2;
gcr.Query = Address1;
var myFunc = Observable.FromAsyncPattern<GeocodeRequest, GeocodeResponse>(gsc.BeginGeocode, gsc.EndGeocode);
gcResp = myFunc(gcr) as GeocodeResponse;
if (gcResp.Results.Count > 0 && gcResp.Results[0].Locations.Count > 0)
{
returnLocation = gcResp.Results[0].Locations[0];
}
return returnLocation as IObservable<Location>;
}
gcResp comes back as null. Any thoughts or suggestions would be greatly appreciated.
The observable source you are subscribing to is asynchronous, so you can't access the result immediately after subscribing. You need to access the result in the subscription.
Better yet, don't subscribe at all and simply compose the response:
private IObservable<Location> GetGPSCoordinates(string Address1)
{
IGeocodeService gsc =
new GeocodeServiceClient("BasicHttpBinding_IGeocodeService");
Location returnLocation = new Location();
GeocodeResponse gcResp = new GeocodeResponse();
GeocodeRequest gcr = new GeocodeRequest();
gcr.Credentials = new Credentials();
gcr.Credentials.ApplicationId = APP_ID2;
gcr.Query = Address1;
var factory = Observable.FromAsyncPattern<GeocodeRequest, GeocodeResponse>(
gsc.BeginGeocode, gsc.EndGeocode);
return factory(gcr)
.Where(response => response.Results.Count > 0 &&
response.Results[0].Locations.Count > 0)
.Select(response => response.Results[0].Locations[0]);
}
If you only need the first valid value (the location of the address is unlikely to change), then add a .Take(1) between the Where and Select.
Edit: If you want to specifically handle the address not being found, you can either return results and have the consumer deal with it or you can return an Exception and provide an OnError handler when subscribing. If you're thinking of doing the latter, you would use SelectMany:
return factory(gcr)
.SelectMany(response => (response.Results.Count > 0 &&
response.Results[0].Locations.Count > 0)
? Observable.Return(response.Results[0].Locations[0])
: Observable.Throw<Location>(new AddressNotFoundException())
);
If you expand out the type of myFunc you'll see that it is Func<GeocodeRequest, IObservable<GeocodeResponse>>.
Func<GeocodeRequest, IObservable<GeocodeResponse>> myFunc =
Observable.FromAsyncPattern<GeocodeRequest, GeocodeResponse>
(gsc.BeginGeocode, gsc.EndGeocode);
So when you call myFunc(gcr) you have an IObservable<GeocodeResponse> and not a GeocodeResponse. Your code myFunc(gcr) as GeocodeResponse returns null because the cast is invalid.
What you need to do is either get the last value of the observable or just do a subscribe. Calling .Last() will block. If you call .Subscribe(...) your response will come thru on the call back thread.
Try this:
gcResp = myFunc(gcr).Last();
Let me know how you go.
Richard (and others),
So I have the code returning the location and I have the calling code subscribing. Here is (hopefully) the final issue. When I call GetGPSCoordinates, the next statement gets executed immediately without waiting for the subscribe to finish. Here's an example in a button OnClick event handler.
Location newLoc = new Location();
GetGPSCoordinates(this.Input.Text).ObserveOnDispatcher().Subscribe(x =>
{
if (x.Results.Count > 0 && x.Results[0].Locations.Count > 0)
{
newLoc = x.Results[0].Locations[0];
Output.Text = "Latitude: " + newLoc.Latitude.ToString() +
", Longtude: " + newLoc.Longitude.ToString();
}
else
{
Output.Text = "Invalid address";
}
});
Output.Text = " Outside of subscribe --- Latitude: " + newLoc.Latitude.ToString() +
", Longtude: " + newLoc.Longitude.ToString();
The Output.Text assignment that takes place outside of Subscribe executes before the Subscribe has finished and displays zeros and then the one inside the subscribe displays the new location info.
The purpose of this process is to get location info that will then be saved in a database record and I am processing multiple addresses sequentially in a Foreach loop. I chose Rx Extensions as a solution to avoid the problem of the async callback as a coding trap. But it seems I have exchanged one trap for another.
Thoughts, comments, suggestions?
