I have a database in the Assets folder of the project and I would try to recover the file of the database, but I get an exception. Can not find the file. What should I change?
SQLiteAsyncConnection mussAll = new SQLiteAsyncConnection("ms-appx:///../Assets/Database1.db", true);
Later I would like to fill a List with objects within the database. is correct to do so?
var queryAll = await mussAll.Table<Musei>().ToListAsync();
List<Musei> listAll = new List<Musei>();
foreach(Musei museiAll in queryAll)
{
listAll.Add(museiAll);
}
var qruppim = listAll.OrderBy(x => x.NomeMuseo).GroupBy(x => x.NomeMuseo.Substring(0, 1));
MuseoDettagli.Source = qruppim;

I'm trying to link a c# application to a sharepoint directory, so I can create folders, download and upload files. However I am strugling with connecting to the correct folder.
I can retrieve the content from allitems.aspx, but I am not sure how to actually get the content from folder.
I have tried using the ClientContext - something like this:
ClientContext cxt = new ClientContext("https://xx.sharepoint.com/sites/");
cxt.Credentials = GetCredentials();
List list = cxt.Web.Lists.GetByTitle("Kontrakter");
var test = list.Views;
var test1 = cxt.Web.Lists;
cxt.Load(test1);
cxt.Load(list);
cxt.Load(test);
var a = 4;
var fullUri = new Uri("https://xx.sharepoint.com/sites/yy/Kontrakter/AllItems.aspx");
//var folder = cxt.Web.GetFolderByServerRelativeUrl(fullUri.AbsolutePath);
using (var rootCtx = new ClientContext(fullUri.GetLeftPart(UriPartial.Authority)))
{
rootCtx.Credentials = GetCredentials();
Uri webUri = Web.WebUrlFromPageUrlDirect(rootCtx, fullUri);
using (var ctx1 = new ClientContext(webUri))
{
ctx1.Credentials = GetCredentials();
var list1 = ctx1.Web.GetList(fullUri.AbsolutePath);
ctx1.Load(list1.RootFolder.Files);
ctx1.ExecuteQuery();
Console.WriteLine(list.RootFolder.Files.Count);
}
}
or via normal api calls like this:
https://xx.sharepoint.com/_api/Web/GetFolderByServerRelativeUrl('Kontrakter/Forms')/Files
The only way I can find some data is if I look into 'Shared documents/Forms'
I'm having problems understanding the directory structure and how I can actually find the content of files/folders.
Thanks in advance :)
Turned out I was missing a /sites in one of my uris.
Here's a reproduction
Using build 2.5.2910
So we store a member in the database the normal way:
await session.StoreAsync(member)
I can then sign in, as that member, when
await session.LoadByUniqueConstraintAsync<Member>(m => m.Email, email)
I then do a batch update of email addresses (the batch only contains that one email address)
for (var batch = 0; (records = allRecords.Skip(batch * BatchSize).Take(BatchSize).ToList()).Any(); batch++)
{
using(var querySession = this.documentStore.OpenSession())
{
var existingMembers = session.Query<Member, Member_ByEmail> ().Where(m => m.Email.In(records.Select(r => r.OldEmailAddress))).ToDictionary(m => m.Email, m => m);
using(var bulkInsertOperation = this.documentStore.BulkInsert(this.systemConfiguration.DatabaseName, new BulkInsertOptions { CheckForUpdates = true }))
{
foreach(var member in records)
{
var existingMemberKey = member.OldEmailAddress;
var existingMemberRecord = existingMembers[existingMemberKey];
existingMemberRecord.Email = member.EmailAddress;
}
}
}
}
When I try and log in again with the new email address, this line:
await session.LoadByUniqueConstraintAsync<Member>(m => m.Email, email)
Returns null....
I've checked the new email being used is the same one in the database. The database shows the new one. I've used the database interface and queried the index for the new email and that works.
I've set the database to use wait for non stale results and also:
store.Conventions.DefaultQueryingConsistency = ConsistencyOptions.AlwaysWaitForNonStaleResultsAsOfLastWrite;
None of these options have worked.
I'm wondering if there is something special I have to do with bulk insert operation in order to get the .NET client to read the indexes for this new email.
I've drilled into the session variable at runtime and found that there is a known missing ids field with this value:
"UniqueConstraints/members/email/Ym1hcmxleTFAbmV3b3JiaXQuY28udWs="
You need to download the Raven plugin Raven.Bundles.UniqueConstraints.dll and add it to the \Plugins\ directory in your Raven installation folder (in my case, D:\RavenDB\Plugins)
You will need to re-insert the records after doing this (I deleted the database and re-seeded).
I created a database with SQLite-net so:
SQLiteAsyncConnection conn = new SQLiteAsyncConnection(Path.Combine(ApplicationData.Current.LocalFolder.Path, "Database.db"), true);
await conn.CreateTableAsync<Musei>();
Musei musPref;
if (muss.NumeroTel != null && muss.Descrizione!=null && muss.indirizzoEmail!= null && muss.Immagine!= null)
{
musPref = new Musei
{
DidascaliaLista=muss.DidascaliaLista,
NomeMuseo = muss.NomeMuseo,
Luogopreciso = muss.Luogopreciso,
Descrizione = muss.Descrizione,
NumeroTel = muss.NumeroTel,
IndirizzoEmail = muss.IndirizzoEmail,
Immagine= muss.Immagine,
};
}
await conn.InsertAsync(musPref);
In another project I need to recover the database created and insert objects inside a ListView, But I do not know how to proceed ..
try
{
StorageFile data = await ApplicationData.Current.LocalFolder.GetFileAsync("Database.db");
}
catch(Exception)
{
}
And now??
I would like to retrieve the database created above and use it, inserting objects "Musei" that are in it and display it in a ListView
If you want to read from the database you created earlier, you can do the following:
// Get a connection to the database that is in the local folder.
var dbPath = Path.Combine(ApplicationData.Current.LocalFolder.Path, "Database.db");
var con = new SQLiteAsyncConnection(dbPath, true);
// Get all "Musei" in the database stored in the "Musei" table.
var results = await con.QueryAsync<Musei>("SELECT * FROM Musei");
If you only want the Musei that match a certain field value, for example: you only want to read those in the specific location "Rome", you can do that like this:
var searchLocation = "Rome"; // for example entered by the user in your UI.
// Get only the "Musei" in `searchLocation`.
var results = await con.QueryAsync<Musei>("SELECT * FROM Musei WHERE Luogopreciso ='?'", searchLocation);
An alternative, if you are only querying a single table, is to do it like this, using LINQ:
var query = con.Table<Musei>();
// or, if looking for `searchLocation`:
var query = con.Table<Musei>().Where(m => m.Luogopreciso == "Rome");
you can then get this as a list using:
var result = await query.ToListAsync();
To find out which tables are actually present in your opened database files, you can do this:
var nTables = 0;
System.Diagnostics.Debug.WriteLine("Tables in the database");
foreach (var mapping in con.TableMappings)
{
System.Diagnostics.Debug.WriteLine(mapping.TableName);
nTables++;
}
System.Diagnostics.Debug.WriteLine("{0} tables in total", nTables);
and look at the debug output.
Is there a way to run a shared team query, by name, through the TFS 2013 client object API
I'm working on a C# script that will do some work based off of the results of a shared team query. I don't want to have to maintain the query in the TFS UI as well as in my script; I'd prefer to just run the registered query that my team uses, but then just play with the results. When I write "registered query" I'm just referring to a query that I wrote in the TFS UI and saved as a shared query.
In other words: I'd like to use the TFS UI to create a query, save the file in my "shared queries" list, call it "foo", then access foo from the client object API in my script.
I see that there is a GetQueryDefinition(GUID) method off of WorkItemStore, but where would I get the GUID for a shared team query?
Sample code that should do what you need
///Handles nested query folders
private static Guid FindQuery(QueryFolder folder, string queryName)
{
foreach (var item in folder)
{
if (item.Name.Equals(queryName, StringComparison.InvariantCultureIgnoreCase))
{
return item.Id;
}
var itemFolder = item as QueryFolder;
if (itemFolder != null)
{
var result = FindQuery(itemFolder, queryName);
if (!result.Equals(Guid.Empty))
{
return result;
}
}
}
return Guid.Empty;
}
static void Main(string[] args)
{
var collectionUri = new Uri("http://TFS/tfs/DefaultCollection");
var server = new TfsTeamProjectCollection(collectionUri);
var workItemStore = server.GetService<WorkItemStore>();
var teamProject = workItemStore.Projects["TeamProjectName"];
var x = teamProject.QueryHierarchy;
var queryId = FindQuery(x, "QueryNameHere");
var queryDefinition = workItemStore.GetQueryDefinition(queryId);
var variables = new Dictionary<string, string>() {{"project", "TeamProjectName"}};
var result = workItemStore.Query(queryDefinition.QueryText,variables);
}
I'm trying to use libgit2sharp to get a previous version of a file. I would prefer the working directory to remain as is, at the very least restored to previous condition.
My initial approach was to try to stash, checkout path on the file I want, save that to a string variable, then stash pop. Is there a way to stash pop? I can't find it easily. Here's the code I have so far:
using (var repo = new Repository(DirectoryPath, null))
{
var currentCommit = repo.Head.Tip.Sha;
var commit = repo.Commits.Where(c => c.Sha == commitHash).FirstOrDefault();
if (commit == null)
return null;
var sn = "Stash Name";
var now = new DateTimeOffset(DateTime.Now);
var diffCount = repo.Diff.Compare().Count();
if(diffCount > 0)
repo.Stashes.Add(new Signature(sn, "x#y.com", now), options: StashModifiers.Default);
repo.CheckoutPaths(commit.Sha, new List<string>{ path }, CheckoutModifiers.None, null, null);
var fileText = File.ReadAllText(path);
repo.CheckoutPaths(currentCommit, new List<string>{path}, CheckoutModifiers.None, null, null);
if(diffCount > 0)
; // stash Pop?
}
If there's an easier approach than using Stash, that would work great also.

Unfortunately, Stash pop requires merging which isn't available yet in libgit2.

You may achieve such result by opening two instances of the same repository, each of them pointing to different working directories. The Repository constructor accepts a RepositoryOptions parameter which should allow you to do just that.
The following piece of code demonstrates this feature. This creates an additional instance (otherRepo) that you can use to retrieve a different version of the file currently checked out in your main working directory.
string repoPath = "path/to/your/repo";
// Create a temp folder for a second working directory
string tempWorkDir = Path.Combine(Path.GetTempPath(), "tmp_wd");
Directory.CreateDirectory(newWorkdir);
// Also create a new index to not alter the main repository
string tempIndex = Path.Combine(Path.GetTempPath(), "tmp_idx");
var opts = new RepositoryOptions
{
WorkingDirectoryPath = tempWorkDir,
IndexPath = tempIndex
};
using (var mainRepo = new Repository(repoPath))
using (var otherRepo = new Repository(mainRepo.Info.Path, opts))
{
string path = "file.txt";
// Do your stuff with mainrepo
mainRepo.CheckoutPaths("HEAD", new[] { path });
var currentVersion = File.ReadAllText(Path.Combine(mainRepo.Info.WorkingDirectory, path));
// Use otherRepo to temporarily checkout previous versions of files
// Thank to the passed in RepositoryOptions, this checkout will not
// alter the workdir nor the index of the main repository.
otherRepo.CheckoutPaths("HEAD~2", new [] { path });
var olderVersion = File.ReadAllText(Path.Combine(otherRepo.Info.WorkingDirectory, path));
}
You can get a better grasp of this RepositoryOptions type by taking a look at the tests in RepositoryOptionFixture that exercise it.
