I want to add named data cache programmatically in appfabric.
I kept following code for this :-
try
{
//This can also be kept in a config file
var config = new DataCacheFactoryConfiguration();
config.SecurityProperties = new DataCacheSecurity();
config.Servers = new List<DataCacheServerEndpoint> { new DataCacheServerEndpoint(Environment.MachineName, 22233) };
DataCacheFactory dcf = new DataCacheFactory(config);
if (dcf != null)
{
var state = InitialSessionState.CreateDefault();
state.ImportPSModule(new string[] { "DistributedCacheAdministration", "DistributedCacheConfiguration" });
state.ThrowOnRunspaceOpenError = true;
var rs = RunspaceFactory.CreateRunspace(state);
rs.Open();
var pipe = rs.CreatePipeline();
pipe.Commands.Add(new Command("Use-CacheCluster"));
var cmd = new Command("New-Cache");
cmd.Parameters.Add(new CommandParameter("Name", "Vaibhav"));
cmd.Parameters.Add(new CommandParameter("Expirable", false));
pipe.Commands.Add(cmd);
var output = pipe.Invoke();
}
}
catch (Exception e)
{
//throw new Exception
}
But this is not working as expected when i try to access the DataCache (using: dcf.GetCache("Vaibhav");) it is giving Cache not found error. When i created the Cache using powershell it worked fine and i was able to access the Cache, but i want to implement this programmactically and not by Command Prompt(powershell)
Please suggest a proper way to implement this....
Thanks in Advance

You actually have to Start the Visual Studio as admin to be able to create Cache programatically.

I am struggling with uploading an image from thew client-side to a folder on the server-side in .Net Core.I used Postman to check if the method on the server-side is working and it does without any problem,but when I try to upload an image from the client-side,I get an error on the server-side of type NullReferenceException:Object reference not set to an instance of an object.This is the Post method on the server-side:
[HttpPost]
public async Task Post(IFormFile file)
{
if (string.IsNullOrWhiteSpace(_environment.WebRootPath))
{
_environment.WebRootPath = Path.Combine(Directory.GetCurrentDirectory(), "wwwroot");
}
var uploads = Path.Combine(_environment.WebRootPath, "uploads");
//var fileName = file.FileName.Split('\\').LastOrDefault().Split('/').LastOrDefault();
if (!Directory.Exists(uploads)) Directory.CreateDirectory(uploads);
if (file.Length > 0)
{
using (var fileStream = new FileStream(Path.Combine(uploads, file.FileName), FileMode.Create))
{
await file.CopyToAsync(fileStream);
}
}
}
Apparently the method is thrown where I check if the length of the file is bigger than 0.On the client-side I get error "500 internal server error" and I tried to check using the debugger where exactly the error is thrown but i can't find anything that could resemble an error of some sort.This is the API method for the client-side:
public async Task UploadPictureAsync(MediaFile image)
{
User user = new User();
string pictureUrl = "http://10.0.2.2:5000/api/UploadPicture";
HttpContent fileStreamContent = new StreamContent(image.GetStream());
// user.Picture=GetImageStreamAsBytes(image.GetStream());
fileStreamContent.Headers.ContentDisposition = new ContentDispositionHeaderValue("form-data") {FileName=Guid.NewGuid() + ".Png",Name="image"};
fileStreamContent.Headers.ContentType = new MediaTypeHeaderValue("application/octet-stream");
HttpClientHandler clientHandler = new HttpClientHandler();
clientHandler.ServerCertificateCustomValidationCallback = (sender, cert, chain, sslPolicyErrors) => { return true; };
using (var client = new HttpClient(clientHandler))
{
using (var formData = new MultipartFormDataContent())
{
formData.Add(fileStreamContent);
var response = await client.PostAsync(pictureUrl, formData);
if(response.IsSuccessStatusCode)
{
var result = response.Content.ReadAsStringAsync().Result;
}
}
}
}
The image is declared in the Model as byte array:
public byte[] Picture { get; set; }
Does someone understand why my POST method has this behavior since the server-side works perfectly but fails when I try to upload an image from the client-side?What I find weird though is that when i read the error and I look at the Content-Type it is "text/plain" instead of "form-data" and I have tried to set it at the MutipartFormDataContent like this:
formData.Headers.ContentType.MediaType = "multipart/form-data";
I also tried to set the MediaTypeHeaderValue on the client like this:
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/octet-stream"));
I still get the wrong content type.
I have also tried a different approach with Stream instead of MediaFile but without any luck as it did not even hit the break point in debugger mode for the response.Any help would be appreciated! :)
I have managed to find the answer finalllyyyyy!!!The problem was on the client-side as I suspected and guess what,it was all about the correct name.It turns out that since on the server side I have IFormFile file I had to change the client side to take the parameter name "file" instead of image as well so that it could work.Thank you #Jason for the suggestions as I didn't understand the error from the first place and did some debugging on the server-side to help me figure it out.
I've tried a number of different options, but no matter what I do it either won't do anything or always return newValue error.
newValue cannot be null.
It seems I'm not the only one but it's had updates since the link below.
docX ReplaceText works incorrect
Below is my original example:-
if (sur.RequestType)
{
templateDoc.ReplaceText("[#1]", "x");
templateDoc.ReplaceText("[#2]", "");
}
else
{
templateDoc.ReplaceText("[#1]", "");
templateDoc.ReplaceText("[#2]", "x");
}
When debugging this it would get to line 4 then jump to line 9 where it would return the newValue cannot be null error on next step.
So I tried:-
string temp1 = "temp1";
if (sur.RequestType)
{
templateDoc.ReplaceText("[#1]", "x");
templateDoc.ReplaceText("[#2]", temp1, false, RegexOptions.IgnoreCase, paraFormat, paraFormat, MatchFormattingOptions.SubsetMatch);
}
else
{
templateDoc.ReplaceText("[#1]", "x.x");
templateDoc.ReplaceText("[#2]", "x", false, RegexOptions.IgnoreCase, paraFormat, paraFormat, MatchFormattingOptions.SubsetMatch);
}
Along with a couple other tweaks but all returning the same error.
Prior to using ReplaceText I'd used the example from the sample project:-
templateDoc.AddCustomProperty( new CustomProperty( "CompanySlogan", "Always with you" ) );
templateDoc.AddCustomProperty( new CustomProperty( "ClientName", "James Doh" ) );
Here it would step through each line but the produced document wouldn't have replaced anything.
Lastly more off topic but if anybody has a better solution, I'd been stuck going back and forth trying to output the file without saving it but had issues converting it from the Xceed DocX type to a HttpResponseMessage.
Below was my least favourable implementation of such as I'd either like to save it to a database or skip saving the file and just provide it directly to the user to save where they want instead of having a server side copy.
[HttpGet]
public HttpResponseMessage DownloadRecord(int id)
{
SURequest sur = _sURequestsService.GetRequestData(id);
var fullPath = System.Web.Hosting.HostingEnvironment.MapPath(#"~/Content/RequestForm.docx");
var fullPath2 = System.Web.Hosting.HostingEnvironment.MapPath(#"~/Content/RequestFormUpdated.docx");
var templateDoc = DocX.Load(fullPath);
var template = CreateRequestFromTemplate(templateDoc, sur);
template.SaveAs(fullPath2);
//using (FileStream fs2 = new FileStream(#"~/Content/RequestFormUpdated.docx", FileMode.Create))
//{
// template.SaveAs(fs2);
//}
HttpResponseMessage result = new HttpResponseMessage(HttpStatusCode.OK);
var stream = new FileStream(fullPath2, FileMode.Open);
result.Content = new StreamContent(stream);
result.Content.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment");
result.Content.Headers.ContentDisposition.FileName = Path.GetFileName(fullPath2);
result.Content.Headers.ContentType = new MediaTypeHeaderValue("application/octet-stream");
result.Content.Headers.ContentLength = stream.Length;
return result;
//return fs2;
}
I'm stuck with no clue how to proceed further with Xceed so am going to branch my present code and try using OpenXML to see if I have any better luck or if someone else can spot what I'm doing wrong or how to get past the issue in Xceed?
Any help would be much appreciated.
Turned out to be an issue with VS17 which was behaving stranging with replacetext and seemed to have cached an earlier issue in it's compiler.
This behaved like the issue was somewhere it wasn't and could only be resolved by manually stopping the compiler process.
Still no resolution for AddCustomProperty or with skipping generating a local file.
I'm going to work on trying to get it not to generate a local file but likely will need to either open a new question specific to that or setup something else to cleanup old files.
I created a class that connected to the API to retrieve the required data using httpclient. That file was called in the code behind file of the view and worked perfectly. Than I decided to implement the MVVM approach. As a result, I moved the code that initialized the rest service class to the view-model.
After doing that, i stopped getting the data. To investigate, I stated the the debugging session with the breakpoint placed at the line where i initialize the rest service class. Than i executed that line. By doing that, I found out that a huge android mono exception is thrown and the debugging session if stopped. The app exits the debugging session.
This has happened for the first time since i stated developing my app in Xamarin Forms. I have no idea about why it is breaking like that. Your help will be greatly appreciated.
This is the code that was working properly.
In the view code behind file
[XamlCompilation(XamlCompilationOptions.Compile)]
public partial class SubtaskPage : ContentPage
{
protected override void OnAppearing()
{
base.OnAppearing();
PopulateSubtaskData();
}
private async void PopulateSubtaskData()
{
lstSubtasks.IsRefreshing = true;
try
{
RestService rs = new RestService();
SResponse = await rs.GetSubtasksAsync(Convert.ToInt32(Application.Current.Properties["UserId"]));
if (SResponse.Status == 1)
{
lstSubtasks.ItemsSource = SResponse.Subtasks;
}
else
{
await DisplayAlert("Error", SResponse.Message, "Ok");
}
}
catch (Exception E)
{
Debug.WriteLine(#"GetSubtasksAsync -> ERROR {0}", E.Message);
}
lstSubtasks.IsRefreshing = false;
}
}
The rest service class is as follows
This class is in a separate folder named "Services". ip and url have been changed for security reason.
class RestService
{
HttpClient client;
public List<Ticket> Tickets { get; private set; }
string Server1 = "server ip";
string Server2 = "server ip";
public RestService()
{
client = new HttpClient();
client.MaxResponseContentBufferSize = 256000;
}
public async Task<SubtasksResponse> GetSubtasksAsync(int UserId)
{
SubtasksResponse SubtaskResponse = new SubtasksResponse();
string ApiUrl = "URL";
string Url = "";
HttpResponseMessage response;
if (CrossConnectivity.Current.IsConnected)
{
Url = await GetActiveServerAsync();
if (Url != "")
{
var uri = string.Format(Url + ApiUrl, UserId);
try
{
response = await client.GetAsync(uri);
if (response.IsSuccessStatusCode)
{
var content = await response.Content.ReadAsStringAsync();
SubtaskResponse.Subtasks = JsonConvert.DeserializeObject<List<Ticket>>(content);
SubtaskResponse.Status = 1;
}
else
{
SubtaskResponse.Subtasks = null;
SubtaskResponse.Status = 0;
SubtaskResponse.Message = "Attempt to fetch data from server was unsuccessful. Please try again";
}
}
catch (Exception E)
{
SubtaskResponse.Subtasks = null;
SubtaskResponse.Status = 0;
SubtaskResponse.Message = "Error occured while fetching data from the server. Please try again";
}
}
else
{
SubtaskResponse.Subtasks = null;
SubtaskResponse.Status = 0;
SubtaskResponse.Message = "Remote Server Not Responding! Please try again later";
}
}
else
{
SubtaskResponse.Subtasks = null;
SubtaskResponse.Status = 0;
SubtaskResponse.Message = "No Network Connection Found! Please connect to a network and try again";
}
return SubtaskResponse;
}
}
}
This was working fine until I added the view model into the mix.
This is how I am calling the function in the view model.
async Task<SubtasksResponse> PopulateSubtaskList()
{
RestService rs = new RestService();
IsBusy = true;
_subtaskList = await rs.GetSubtasksAsync(Convert.ToInt32(Application.Current.Properties["UserId"]));
IsBusy = false;
return _subtaskList;
}
"RestService rs = new RestService();" this is the line where the code breaks.
Here is the image of the exception that occurs when the code breaks.
Hope you get the clear picture of the situation. Please let me know if additional information is required.
Thanks
Don't do this. If you want to call rest from a mvvm Xamarin Forms app I can advice Refit. All the difficult work is already done for you and abstracted away. With a few lines of code you are up and running.
BTW the error message you are showing probably has nothing to do with your code but is a bug in a recent Xamarin version. See here: https://bugzilla.xamarin.com/show_bug.cgi?id=56787
Found the answer on this page (https://releases.xamarin.com/common-issues-in-the-xamarin-15-2-2-release-being-tracked-by-the-xamarin-team/).
The solution is as follows
Download the missing Mono.Posix file and unzip the archive.
Right-click the Mono.Posix.dll file in Explorer and select Properties.
Check the Digital Signatures tab to ensure the file shows a valid Xamarin Inc. signature.
At the bottom of the General tab, if an Unblock checkbox appears, enable it and select OK. (This checkbox appears depending on how the file was downloaded.)
For Visual Studio 2017, copy the Mono.Posix.dll file into the “Xamarin.VisualStudio” extension directory. For example, for a default installation of the Enterprise edition, copy the file into:
C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Common7\IDE\Extensions\Xamarin.VisualStudio
For Visual Studio 2015, copy the file into the “Xamarin\Xamarin” extension directory:
C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\Extensions\Xamarin\Xamarin\
Quit and restart Visual Studio.

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);
}
}
}
}
I was trying to save multiple images into isolated storage by using creating a imageFolder in isolated storage and storing all my images inside.But it have an error so please anyone could help me solve the error or got other method way help me thanks.IF possible I would appreciate if you guys can show me your code that works. Actually my code would like to be under a button event handler.Thanks And the error is :Operation not permitted on IsolatedStorageFileStream.
My Code :
private void SaveToLocalStorage(string imageFolder, string imageFileName)
{
imageFileName = name.Text;
MessageBox.Show(imageFileName);
var isf = IsolatedStorageFile.GetUserStoreForApplication();
if (isf.DirectoryExists(imageFolder))
{
isf.CreateDirectory(imageFolder);
}
string filePath = Path.Combine(imageFolder, imageFileName);
MessageBox.Show(filePath);
using (var stream = isf.CreateFile(filePath))
{
var bmp= new WriteableBitmap(inkCanvas, inkCanvas.RenderTransform);
bmp.SaveJpeg(stream, bmp.PixelWidth, bmp.PixelHeight, 0, 100);
}
}
First off, you probably want to be creating the directory if it DOESN'T exist, not if it does:
if (!isf.DirectoryExists(imageFolder))
{
isf.CreateDirectory(imageFolder);
}
