I'm creating a setup project for WCF net-tcp service. One thing I came across is that I need to change "Web Site->Manage Application->Advanced settings->Enabled Protocols". It can be also done using command line:
%windir%\system32\inetsrv\appcmd.exe set app "[Web Site Name]/[Applicaiton Name]" /enabledProtocols:http,net.tcp
The problem is in custom action I can get [TARGETSITE] but it's value is "/LM/W3SVC/2" (I have [TARGETVDIR] too). The question is how can I get Web Site Name or how can I use [TARGETSITE] to set application enabled protocols?
The solution I ended with involves converting metabasePath to site name and then using appcmd:
private static string GetSiteName(string metabasePath)
{
var siteIdString = metabasePath.Substring(metabasePath.LastIndexOf("/") + 1);
long siteId;
long.TryParse(siteIdString, out siteId);
if (siteId != 0)
{
var iisManager = new ServerManager();
var config = iisManager.GetApplicationHostConfiguration();
var sites = config.GetSection("system.applicationHost/sites").GetCollection();
ConfigurationElement selectedSite = null;
foreach (var site in sites)
{
if ((long)site.GetAttribute("id").Value == siteId)
selectedSite = site;
}
if (selectedSite != null)
{
return selectedSite.GetAttribute("name").Value as string;
}
}
return null;
}
To use this you will have to reference:
C:\Windows\System32\inetsrv\Microsoft.Web.Administration.dll
C:\Windows\System32\inetsrv\Microsoft.Web.Management.dll

I am trying to create a simple Xamarin forms app which allows the user to browse for or take a photo and have azure cognitive services tag the photo using a custom vision model.
I am unable to get the client to successfully authenticate or find a resource per the error message in the exception produced by the VisionServiceClient. Am I missing something? What would be the correct values to use for the arguments to VisionServiceClient?
All keys have been removed from the below images, they are populated.
Exception thrown in VS2017:
'Microsoft.ProjectOxford.Vision.ClientException' in System.Private.CoreLib.dll
Call to VisionServiceClient:
private const string endpoint = #"https://eastus2.api.cognitive.microsoft.com/vision/prediction/v1.0";
private const string key = "";
VisionServiceClient visionClient = new VisionServiceClient(key, endpoint);
VisualFeature[] features = { VisualFeature.Tags, VisualFeature.Categories, VisualFeature.Description };
try
{
AnalysisResult temp = await visionClient.AnalyzeImageAsync(imageStream,
features.ToList(), null);
return temp;
}
catch(Exception ex)
{
return null;
}
VS Exception Error:
Azure Portal for cognitive services:
Custom Vision Portal:
It looks like you're confusing the Computer Vision and the Custom Vision APIs. You are attempting to use the client SDK for the former using the API key of the latter.
For .NET languages, you'll want the Microsoft.Azure.CognitiveServices.Vision.CustomVision.Prediction NuGet package.
Your code will end up looking something like this:
ICustomVisionPredictionClient client = new CustomVisionPredictionClient()
{
ApiKey = PredictionKey,
Endpoint = "https://southcentralus.api.cognitive.microsoft.com"
};
ImagePrediction prediction = await client.PredictImageAsync(ProjectId, stream, IterationId);
Thank you to cthrash for the extended help and talking with me in chat. Using his post along with a little troubleshooting I have figured out what works for me. The code is super clunky but it was just to test and make sure I'm able to do this. To answer the question:
Nuget packages and classes
Using cthrash's post I was able to get both the training and prediction nuget packages installed, which are the correct packages for this particular application. I needed the following classes:
Microsoft.Azure.CognitiveServices.Vision.CustomVision.Prediction
Microsoft.Azure.CognitiveServices.Vision.CustomVision.Prediction.Models
Microsoft.Azure.CognitiveServices.Vision.CustomVision.Training
Microsoft.Azure.CognitiveServices.Vision.CustomVision.Training.Models
Endpoint Root
Following some of the steps Here I determined that the endpoint URL's only need to be the root, not the full URL provided in the Custom Vision Portal. For instance,
https://southcentralus.api.cognitive.microsoft.com/customvision/v2.0/Prediction/
Was changed to
https://southcentralus.api.cognitive.microsoft.com
I used both the key and endpoint from the Custom Vision Portal and making that change I was able to use both a training and prediction client to pull the projects and iterations.
Getting Project Id
In order to use CustomVisionPredictionClient.PredictImageAsync you need a Guid for the project id and an iteration id if a default iteration is not set in the portal.
I tested two ways to get the project id,
Using project id string from portal
Grab the project id string from the portal under the project settings.
For the first argument to PredictImageAsync pass
Guid.Parse(projectId)
Using the training client
Create a new CustomVisionTrainingClient
To get a list of <Project> use
TrainingClient.GetProjects().ToList()
In my case I only had a single project so I would just need the first element.
Guid projectId = projects[0].Id
Getting Iteration Id
To get the iteration id of a project you need the CustomVisionTrainingClient.
Create the client
To get a list of <Iteration> use
client.GetIterations(projectId).ToList()
In my case I had only a single iteration so I just need the first element.
Guid iterationId = iterations[0].Id
I am now able to use my model to classify images. In the code below, fileStream is the image stream passed to the model.
public async Task<string> Predict(Stream fileStream)
{
string projectId = "";
//string trainingEndpoint = "https://southcentralus.api.cognitive.microsoft.com/customvision/v2.2/Training/";
string trainingEndpoint = "https://southcentralus.api.cognitive.microsoft.com/";
string trainingKey = "";
//string predictionEndpoint = "https://southcentralus.api.cognitive.microsoft.com/customvision/v2.0/Prediction/";
string predictionEndpoint = "https://southcentralus.api.cognitive.microsoft.com";
string predictionKey = "";
CustomVisionTrainingClient trainingClient = new CustomVisionTrainingClient
{
ApiKey = trainingKey,
Endpoint = trainingEndpoint
};
List<Project> projects = new List<Project>();
try
{
projects = trainingClient.GetProjects().ToList();
}
catch(Exception ex)
{
Debug.WriteLine("Unable to get projects:\n\n" + ex.Message);
return "Unable to obtain projects.";
}
Guid ProjectId = Guid.Empty;
if(projects.Count > 0)
{
ProjectId = projects[0].Id;
}
if (ProjectId == Guid.Empty)
{
Debug.WriteLine("Unable to obtain project ID");
return "Unable to obtain project id.";
}
List<Iteration> iterations = new List<Iteration>();
try
{
iterations = trainingClient.GetIterations(ProjectId).ToList();
}
catch(Exception ex)
{
Debug.WriteLine("Unable to obtain iterations.");
return "Unable to obtain iterations.";
}
foreach(Iteration itr in iterations)
{
Debug.WriteLine(itr.Name + "\t" + itr.Id + "\n");
}
Guid iteration = Guid.Empty;
if(iterations.Count > 0)
{
iteration = iterations[0].Id;
}
if(iteration == Guid.Empty)
{
Debug.WriteLine("Unable to obtain project iteration.");
return "Unable to obtain project iteration";
}
CustomVisionPredictionClient predictionClient = new CustomVisionPredictionClient
{
ApiKey = predictionKey,
Endpoint = predictionEndpoint
};
var result = await predictionClient.PredictImageAsync(Guid.Parse(projectId), fileStream, iteration);
string resultStr = string.Empty;
foreach(PredictionModel pred in result.Predictions)
{
if(pred.Probability >= 0.85)
resultStr += pred.TagName + " ";
}
return resultStr;
}
I am ruing my website on azure, every folder is present on site directory in azure but uploadimages is my sub folder of content is absent from wwwroot, and images is not uploading also
I am using
var path =Path.Combine(Server.MapPath("~/Content/UploadImages/")+filename);
same with document upload
According to your description, I have tested on my side, please follow below to find out whether it could help you.
As you said, you got the target file path by this code:
var path = Path.Combine(Server.MapPath("~/Content/UploadImages/") + filename);
Before uploading files, please make sure that the directory in your web server “~/Content/UploadImages/” is existed.
Here is my test code:
MVC controller method
[HttpPost]
public JsonResult UploadFiles()
{
try
{
foreach (string file in Request.Files)
{
var fileContent = Request.Files[file];
if (fileContent != null && fileContent.ContentLength > 0)
{
var stream = fileContent.InputStream;
var fileName = Path.GetFileName(fileContent.FileName);
string baseDir = Server.MapPath("~/Content/UploadImages/");
if (!Directory.Exists(baseDir))
Directory.CreateDirectory(baseDir);
var path = Path.Combine(baseDir, fileName);
using (var fileStream = System.IO.File.Create(path))
{
stream.CopyTo(fileStream);
}
}
}
}
catch (Exception e)
{
return Json(new
{
Flag = false,
Message = string.Format("File Uploaded failed with exception:{0}", e.Message)
});
}
return Json(new
{
Flag = true,
Message = "File uploaded successfully!"
});
}
Additionally, for long-term consideration, you could store your files on Azure Blob Storage which could bring you some benefits, such as:
1.Serving images or documents directly to a browser
2.Storing files for distributed access
3.When you scale up your site, your site could run in multiple Web Server instances which could access the same files & docs simultaneously
For more details, please refer to this link: https://azure.microsoft.com/en-us/documentation/articles/storage-dotnet-how-to-use-blobs/
I'm working on a project team and our application is in TFS. I'm attempting to determine how many lines of code each team member is responsible. In TFS, I'm aware of the Annotate feature in the Visual Studio interface which allows you to see who last modified each line of code so I know TFS has this information.
I've written a small console app which accesses my TFS project and all its files, but I now need to programmatically access annotations so I can see who the owner of each line is. Here is my existing code:
using Microsoft.TeamFoundation.Client;
using Microsoft.TeamFoundation.VersionControl.Client;
public class Program
{
static void Main(string[] args)
{
var credentials = new NetworkCredential(username, password, domain);
var server = new TfsTeamProjectCollection(new Uri(serverUrl), credentials);
var version = server.GetService(typeof(VersionControlServer)) as VersionControlServer;
var items = version.GetItems(projectPath, RecursionType.Full);
var fileItems = items.Items.Where(x => x.ItemType == ItemType.File);
foreach (var fileItem in fileItems)
{
var serverItem = fileItem.ServerItem;
//TODO: retrieve and parse annotations
}
}
}
I can't seem to figure out how to retrieve annotations once I have the TFS item. This link explains how to do it by calling TFPT, but after implementing it (tfpt annotate /noprompt <filename>), you are only give the last changeset and code per line, not the owner.
I also found a Microsoft.TeamFoundation.VersionControl.Server namespace that has an Annotation class. I installed TFS on my machine to have access to that DLL, but it doesn't seem like it is of any help to this problem.
How can you programmatically access TFS annotations to determine the owner of a line of code for a file?
You may have to query the branch when a Item's change type is Branch.
For a simple example, there is a scenario
$/Project
/Main`
/a.txt
/Develop
/a.txt (branched from main)
When you query the history of $/project/Develop/a.txt, you can also get the history of $/project/Main/a.txt using following code
void GetAllHistory(string serverItem)
{
var changesets=vcs.QueryHistory(serverItem,
Microsoft.TeamFoundation.VersionControl.Client.VersionSpec.Latest,
0,
Microsoft.TeamFoundation.VersionControl.Client.RecursionType.None,
null,
new Microsoft.TeamFoundation.VersionControl.Client.ChangesetVersionSpec(1),
Microsoft.TeamFoundation.VersionControl.Client.VersionSpec.Latest,
int.MaxValue,
true,
false);
foreach (var obj in changesets)
{
Microsoft.TeamFoundation.VersionControl.Client.Changeset cs = obj as Microsoft.TeamFoundation.VersionControl.Client.Changeset;
if (cs == null)
{
return;
}
foreach (var change in cs.Changes)
{
if (change.Item.ServerItem != serverItem)
{
return;
}
Console.WriteLine(string.Format("ChangeSetID:{0}\tFile:{1}\tChangeType:{2}", cs.ChangesetId,change.Item.ServerItem, change.ChangeType));
if ((change.ChangeType & Microsoft.TeamFoundation.VersionControl.Client.ChangeType.Branch) == Microsoft.TeamFoundation.VersionControl.Client.ChangeType.Branch)
{
var items=vcs.GetBranchHistory(new Microsoft.TeamFoundation.VersionControl.Client.ItemSpec[]{new Microsoft.TeamFoundation.VersionControl.Client.ItemSpec(serverItem, Microsoft.TeamFoundation.VersionControl.Client.RecursionType.None)},
Microsoft.TeamFoundation.VersionControl.Client.VersionSpec.Latest);
GetAllHistory(items[0][0].Relative.BranchToItem.ServerItem);
}
}
}
}
Since I have to activate Sharepoint Site Collection Feature programmatically, I have added FeatureEventReceiver to the solution. Here is my code,
public override void FeatureInstalled(SPFeatureReceiverProperties properties) {
SPSecurity.RunWithElevatedPrivileges(delegate()
{
using (SPSite site = new SPSite("http://itcdev33"))
{
using (SPWeb web = site.RootWeb)
{
web.AllowUnsafeUpdates = true;
site.AllowUnsafeUpdates = true;
Guid myid = new Guid("32529c03-833d-4c5e-a15e-0bcb35bdedad");
if (site.Features[myid] == null)
{
site.Features.Add(myid, true, SPFeatureDefinitionScope.Site);
}
web.Update();
site.AllowUnsafeUpdates = false;
web.AllowUnsafeUpdates = false;
}
}
});
}
Issue is solved, it is not possible to activate same feature in its feature installed event, when the feature is installed. So I used the method known as feature stapling, which works and feature is installed when the solution is deployed.
Hello i am currently developing a kind of wiki system for my school, this system uses sub domains to find what course the wiki belongs to. example math1.wiki.com will be the course Math 1.
Now all these wikis use the same database and are given a wiki id, to find what data to load.
Here is the code i use to find the wiki id.
Global.asax
protected void Session_Start()
{
var database = new DataContext();
IWikiRepository rep = new WikiRepository(database);
IWikiService service = new WikiService(rep);
var domain = HttpContext.Current.Request.Url.Authority;
var port = "";
if (domain.Contains(':'))
{
var tmp = domain.Split(':');
domain = tmp[0];
port = tmp[1];
}
var split = domain.Split('.');
var subdomain = split[0];
// if (subdomain == "localhost")
// subdomain = "wiki1";
var wiki = service.GetSite(subdomain);
if (wiki == null)
{
Response.StatusCode = 404;
return;
}
Session["CurrentWiki"] = wiki;
}
This is all fine, but i want to make the mvc system send a 404 request if no wiki was found for the subdomain. But this can not only be done in session_start() as it only runs once per session i have therefor tryed using Application_BeginRequest, but sadly do i not have access to the sessions in the method.
Do any one know how i can implement this?
why can't you just make a custom function that you call at the start of the main page to determine if the wiki exists and if not, redirect/error page/whatever. If it's a custom function, you can just recall it when necessary.
