Windows azure - the specified table not found - visual-studio-2010

I'm trying to get the daa from windows azure storage but I'm getting table not found. I've already saw the others answers but nothing works...
I did try this:
private void popula()
{
var account = CloudStorageAccount.Parse(RoleEnvironment.GetConfigurationSettingValue("Conn"));
account.CreateCloudTableClient().CreateTableIfNotExist("fiscal");
var context = new CRUDManifestacoesEntities(account.TableEndpoint.ToString(), account.Credentials);
Hashtable ht = (Hashtable)ViewState["filtro"];
var teste = ViewState["x"].ToString();
if (ht == null)
GridView1.DataSource = context.SelectConc(teste);
else
GridView1.DataSource = context.SelectConc(ht);
}
public List<ManifestacaoGrid> SelectConc(string conc)
{
conc = Crypto.DecryptString(conc);
IQueryable<ManifestacaoEntity> results = null;
if (!conc.Equals("dfg"))
results = from c in ManifestacaoEntities where c.concessionaria == conc select c;
else
results = from c in ManifestacaoEntities select c;
var query = results.AsTableServiceQuery<ManifestacaoEntity>();
var queryResults = query.Execute();
List<ManifestacaoGrid> al = new List<ManifestacaoGrid>();
foreach (ManifestacaoEntity mf in queryResults)
{
.......
}
I'm getting this error:
TableNotFoundThe table specified does not exist.
RequestId:285f6ef7-b1ce-4c21-9406-3e9f6a58755b
Time:2014-01-15T14:30:55.7989535Z
EDIT: I did print '_account' to see if the credentials are correct:
var credencial = "Connection string with sensitive data: " + account.ToString(true);
and the AccountName and AccountKey are correct ...but how can I know if the requested table is correct?
The secundary key is needed in storage account?

I did found the problem. I write
public IQueryable<UserEntity> UserEntities
{
get
{
return this.CreateQuery<UserEntity>("tableName");
}
}
Instead of:
public IQueryable<UserEntity> UserEntities
{
get
{
return this.CreateQuery<UserEntity>("UserEntities");
}
}

How can improve this Linq query expressions performance?

public bool SaveValidTicketNos(string id,string[] ticketNos, string checkType, string checkMan)
{
bool result = false;
List<Carstartlistticket>enties=new List<Carstartlistticket>();
using (var context = new MiniSysDataContext())
{
try
{
foreach (var ticketNo in ticketNos)
{
Orderticket temp = context.Orderticket.ByTicketNo(ticketNo).SingleOrDefault();
if (temp != null)
{
Ticketline ticketline= temp.Ticketline;
string currencyType = temp.CurrencyType;
float personAllowance=GetPersonCountAllowance(context,ticketline, currencyType);
Carstartlistticket carstartlistticket = new Carstartlistticket()
{
CsltId = Guid.NewGuid().ToString(),
Carstartlist = new Carstartlist(){CslId = id},
LeaveDate = temp.LeaveDate,
OnPointName = temp.OnpointName,
OffPointName = temp.OffpointName,
OutTicketMan = temp.OutBy,
TicketNo = temp.TicketNo,
ChekMan = checkMan,
Type = string.IsNullOrEmpty(checkType)?(short?)null:Convert.ToInt16(checkType),
CreatedOn = DateTime.Now,
CreatedBy = checkMan,
NumbserAllowance = personAllowance
};
enties.Add(carstartlistticket);
}
}
context.BeginTransaction();
context.Carstartlistticket.InsertAllOnSubmit(enties);
context.SubmitChanges();
bool changeStateResult=ChangeTicketState(context, ticketNos,checkMan);
if(changeStateResult)
{
context.CommitTransaction();
result = true;
}
else
{
context.RollbackTransaction();
}
}
catch (Exception e)
{
LogHelper.WriteLog(string.Format("CarstartlistService.SaveValidTicketNos({0},{1},{2},{3})",id,ticketNos,checkType,checkMan),e);
context.RollbackTransaction();
}
}
return result;
}
My code is above. I doubt these code have terrible poor performance. The poor performance in the point
Orderticket temp = context.Orderticket.ByTicketNo(ticketNo).SingleOrDefault();
,actually, I got an string array through the method args,then I want to get all data by ticketNos from database, here i use a loop,I know if i write my code like that ,there will be cause performance problem and it will lead one more time database access,how can avoid this problem and improve the code performance,for example ,geting all data by only on databse access
I forget to tell you the ORM I use ,en ,the ORM is PlinqO based NHibernate
i am looking forward to having your every answer,thank you
using plain NHibernate
var tickets = session.QueryOver<OrderTicket>()
.WhereRestrictionOn(x => x.TicketNo).IsIn(ticketNos)
.List();
short? type = null;
short typeValue;
if (!string.IsNullOrEmpty(checkType) && short.TryParse(checkType, out typeValue))
type = typeValue;
var entitiesToSave = tickets.Select(ticket => new Carstartlistticket
{
CsltId = Guid.NewGuid().ToString(),
Carstartlist = new Carstartlist() { CslId = id },
LeaveDate = ticket.LeaveDate,
OnPointName = ticket.OnpointName,
OffPointName = ticket.OffpointName,
OutTicketMan = ticket.OutBy,
TicketNo = ticket.TicketNo,
ChekMan = checkMan,
CreatedOn = DateTime.Now,
CreatedBy = checkMan,
Type = type,
NumbserAllowance = GetPersonCountAllowance(context, ticket.Ticketline, ticket.CurrencyType)
});
foreach (var entity in entitiesToSave)
{
session.Save(entity);
}
to enhance this further try to preload all needed PersonCountAllowances

How to: linq query

I am trying to get a record from database using linq but it keep return no record
it is very basic sql statment
select * where productid ='12553'
however the following code does not return any result. Please advise. thx you
private static IEnumerable<ProductModel> GetAllProduct(string productId)
{
using (var dc = new TestEntities())
{
var result = (from a in dc.Products
where a.productid == productId
select new ProductModel
{
ProductId = a.productid,
Name = a.ProductName
});
return result.Distinct().ToList();
}
}
You don't need projection here:
using (var dc = new TestEntities())
{
var result = from a in dc.Products
where a.productid == productId
select a;
return result.Distinct().ToList();
}

Windows Azure Storage - Table not found

I'm trying to implement windows azure table storage...but I'm getting 'Table Not Found'
Here is my connection string(How post I xml here?)(sorry for links)
ServiceConfiguration.Cloud.cscfg:
http://pastebin.com/F9tuckfT
ServiceConfiguration.Local.cscfg:
http://pastebin.com/XZHEvv6g
and here there's a print screen from my windows azure portal
http://s20.postimage.org/nz1sxq7hp/print.png
The code(sorry for the longer code...but there's three pages...Login works, when I log in, go to main.aspx that call grid.aspx ...In grid.aspx I get the error "Table not found" All this code is important for the question.....) http://pastebin.com/RnuvvqsM
I have tried
private void popula()
{
var account = CloudStorageAccount.Parse(RoleEnvironment.GetConfigurationSettingValue("Conn"));
account.CreateCloudTableClient().CreateTableIfNotExist("fiscal");
var context = new CRUDManifestacoesEntities(account.TableEndpoint.ToString(), account.Credentials);
Hashtable ht = (Hashtable)ViewState["filtro"];
if (ht == null)
GridView1.DataSource = context.SelectConc(ViewState["x"].ToString());
else
GridView1.DataSource = context.SelectConc(ht);
GridView1.DataBind();
}
but it doesn't work too
Other error similar is when I try to add a USER in table
public string addusr(string nome, string cidade, string cpf, string email, string telefone)
{
try
{
if (nome.Length == 0)
return "f:Preencha o campo nome.";
if (cidade.Length == 0)
return "f:Preencha o campo cidade.";
if (cpf.Length == 0)
return "f:Preencha o campo cpf.";
if (!Valida(cpf))
return "f:CPF Invalido.";
if (email.Length == 0)
return "f:Preencha o campo email.";
Regex rg = new Regex(#"^[A-Za-z0-9](([_\.\-]?[a-zA-Z0-9]+)*)#([A-Za-z0-9]+)(([\.\-]?[a-zA-Z0-9]+)*)\.([A-Za-z]{2,})$");
if (!rg.IsMatch(email))
{
return "f:Email Invalido";
}
List<UserEntity> lst = new List<UserEntity>();
var _account = CloudStorageAccount.Parse(RoleEnvironment.GetConfigurationSettingValue("Conn"));

var account = CloudStorageAccount.Parse(RoleEnvironment.GetConfigurationSettingValue("Conn"));
account.CreateCloudTableClient().CreateTableIfNotExist("fiscal");
var context = new CRUDUserEntities(account.TableEndpoint.ToString(), account.Credentials);
UserClientEntity entity = new UserClientEntity() { nome = nome, cidade = cidade, cpf = cpf, email = email, telefone = telefone };
context.ADDUSociate(entity);
context.SaveChanges();
return "k";
}
I'm getting this error:
f:An error occurred while processing this request.| at System.Data.Services.Client.DataServiceContext.SaveResult.HandleBatchResponse()

at AzureTableLayer.CRUDUserEntities.ADDUSociate(UserClientEntity entity)
at mobile.Service1.addusr(String nome, String cidade, String cpf, String email, String telefone)
I believe that the two problems are related
EDIT: I have debugged and discovered that the StorageClient framework could not be loaded...
I'm getting this error Could not load file or assembly Microsoft.WindowsAzure.StorageClient, Version=1.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'
How to solve?
How are you trying to work with Table Storage? Trought the .NET SDK? PHP? Java? Node? ... Typically if you get this error it means that... the table does not exist.
Check the SDK you're using for a method similar to CreateIfNotExists in order to create the table before you start using it.
Edit:
The issue probably happens here:
var account = CloudStorageAccount.Parse(RoleEnvironment.GetConfigurationSettingValue("Conn"));
var context = new CRUDManifestacoesEntities(account.TableEndpoint.ToString(), account.Credentials);
Hashtable ht = (Hashtable)ViewState["filtro"];
if (ht == null)
GridView1.DataSource = context.SelectConc(ViewState["x"].ToString());
else
GridView1.DataSource = context.SelectConc(ht);
Add the following code after the var account = ... line:
account.CreateCloudTableClient().CreateTableIfNotExist("<name of your table>");
The API has been changed. you need to do it like this:
var key = CloudConfigurationManager.GetSetting("Setting1");
CloudStorageAccount storageAccount = CloudStorageAccount.Parse(key);
var client = storageAccount.CreateCloudTableClient();
CloudTable table = client.GetTableReference(ContactTableName);
table.CreateIfNotExists();

Multiple result set from SQL Via LiNQ

I have a stored procedure as
pr___GetArchiveData
Select * from TABLE1
SELECT * FROM TABLE2
SELECT * FROM TABLE 3
I want to get this result set into a dataset. Or access the values of three select queries!!
I have a DBML file in which when i drag and drop the stored procedure generates a code as follows:-
global::System.Data.Linq.Mapping.FunctionAttribute(Name="dbo.pr___GetArchiveData")]
public ISingleResult<pr___GetArchiveDataResult> pr___GetArchiveData([global::System.Data.Linq.Mapping.ParameterAttribute(DbType="UniqueIdentifier")] System.Nullable<System.Guid> projectID)
{
IExecuteResult result = this.ExecuteMethodCall(this, ((MethodInfo)(MethodInfo.GetCurrentMethod())), projectID);
return ((ISingleResult<pr__Project_pr___GetArchiveData>)(result.ReturnValue));
}
In the code MVC3 Architecture + LINQ i have written a code to get the result set as follows :-
using (HBDataContext hb = new HBDataContext())
{
System.Data.DataSet ds = new System.Data.DataSet();
String connString = connString;
var conn = new System.Data.SqlClient.SqlConnection(connString);
var cmd = conn.CreateCommand();
cmd.CommandType = System.Data.CommandType.StoredProcedure;
cmd.CommandText = "pr__GetArchiveData";
cmd.Connection.Open();
var mReader = cmd.ExecuteReader(System.Data.CommandBehavior.SequentialAccess);
//var reader = cmd.ExecuteReader();
//using (System.Data.SqlClient.SqlDataReader mReader = cmd.ExecuteReader())
//{
// while (mReader.Read())
//{
// mReader.Read();
var tbl1 = hb.Translate<tbl1 >(mReader).ToList();
// mReader = cmd.ExecuteReader();
mReader.NextResult();
var tbl2 = hb.Translate<tbl2 >(mReader).ToList();
mReader.NextResult();
var tbl3 = hb.Translate<tbl3>(mReader).ToList();
// }
// }
}
But while running it throws error as -
"Invalid attempt to call NextResult when reader is closed."
I am not sure where i am wrong!!
I have tried using it as while
(mReader.Read())
Kindly suggest!!!!
The code gen for ISingleResult won't provide multiple result sets
Try adding your own IMultipleResults wrapper - see the tutorial in http://blogs.msdn.com/b/dditweb/archive/2008/05/06/linq-to-sql-and-multiple-result-sets-in-stored-procedures.aspx
In .dbml file for the stored procedure the code will be like
[global::System.Data.Linq.Mapping.FunctionAttribute(Name="dbo.pr__Home_GetArchiveData")]
public ISingleResult<pr__Home_GetArchiveData> pr__Home_GetArchiveData([global::System.Data.Linq.Mapping.ParameterAttribute(Name="AlbumID", DbType="UniqueIdentifier")] System.Nullable<System.Guid> albumID)
{
IExecuteResult result = this.ExecuteMethodCall(this, ((MethodInfo)(MethodInfo.GetCurrentMethod())), albumID);
return ((ISingleResult<pr__Album_GetAlbumsFilesResult>)(result.ReturnValue));
}
Replace it with IMultipleResult as below `
[global::System.Data.Linq.Mapping.FunctionAttribute(Name = "dbo.pr__Home_GetArchiveData")]
[ResultType(typeof(tbl1))]
[ResultType(typeof(tbl2))]
[ResultType(typeof(tbl3))]
[ResultType(typeof(tbl4))]
public IMultipleResults pr__Home_GetArchiveData([global::System.Data.Linq.Mapping.ParameterAttribute(Name = "HOMEID", DbType = "UniqueIdentifier")] System.Nullable hOMEID)
{
IExecuteResult result = this.ExecuteMethodCall(this, ((MethodInfo)(MethodInfo.GetCurrentMethod())), hOMEID);
return ((IMultipleResults)result.ReturnValue);
}
in the code .
using (HBDataContext hb = new HBDataContext())
{
using (System.Data.Linq.IMultipleResults _results = hb.pr__Home_GetArchiveData(model.HomeID))
{
List<tbl1> _tbl1= _results.GetResult<tbl1>().ToList();
List<tbl2> _tbl2= _results.GetResult<tbl2>().ToList();
List<tbl3> _tbl3= _results.GetResult<tbl3>().ToList();
List<tbl4> _tbl4= _results.GetResult<tbl4>().ToList();}}
You will get the values of the Select queries from theStoredProcedure ...

How do I retrieve global contacts with Exchange Web Services (EWS)?

I am using EWS and wish to obtain the global address list from exchange for the company. I know how to retrieve the personal contact list.
All the samples in the API documentation deal with updating user information but not specifically how to retrieve them.
I've even tried the following to list the folders but it doesn't yeild the correct results.
private static void ListFolder(ExchangeService svc, FolderId parent, int depth) {
string s;
foreach (var v in svc.FindFolders(parent, new FolderView(int.MaxValue))) {
Folder f = v as Folder;
if (f != null) {
s = String.Format("[{0}]", f.DisplayName);
Console.WriteLine(s.PadLeft(s.Length + (depth * 2)));
ListFolder(svc, f.Id, depth + 1);
try {
foreach (Item i in f.FindItems(new ItemView(20))) {
Console.WriteLine(
i.Subject.PadLeft(i.Subject.Length + ((depth + 1) * 2)));
}
} catch (Exception) {
}
}
}
}
While the question has already been raised (How to get contact list from Exchange Server?) this question deals specifically with using EWS to get the global address list while this question asks for advice on a general level.
you may got ItemType objects in a specifiedfolder with the code snippet below
and then cast ItemType objects to ContactItemType (for contact objects) ....
/// <summary>
/// gets list of ItemType objects with maxreturncriteria specicification
/// </summary>
/// <param name="esb">ExchangeServiceBinding object</param>
/// <param name="folder">FolderIdType to get items inside</param>
/// <param name="maxEntriesReturned">the max count of items to return</param>
public static List<ItemType> FindItems(ExchangeServiceBinding esb, FolderIdType folder, int maxEntriesReturned)
{
List<ItemType> returnItems = new List<ItemType>();
// Form the FindItem request
FindItemType request = new FindItemType();
request.Traversal = ItemQueryTraversalType.Shallow;
request.ItemShape = new ItemResponseShapeType();
request.ItemShape.BaseShape = DefaultShapeNamesType.AllProperties;
request.ParentFolderIds = new FolderIdType[] { folder };
IndexedPageViewType indexedPageView = new IndexedPageViewType();
indexedPageView.BasePoint = IndexBasePointType.Beginning;
indexedPageView.Offset = 0;
indexedPageView.MaxEntriesReturned = 100;
indexedPageView.MaxEntriesReturnedSpecified = true;
request.Item = indexedPageView;
FindItemResponseType response = esb.FindItem(request);
foreach (FindItemResponseMessageType firmtMessage in response.ResponseMessages.Items)
{
if (firmtMessage.ResponseClass == ResponseClassType.Success)
{
if (firmtMessage.RootFolder.TotalItemsInView > 0)
foreach (ItemType item in ((ArrayOfRealItemsType)firmtMessage.RootFolder.Item).Items)
returnItems.Add(item);
//Console.WriteLine(item.GetType().Name + ": " + item.Subject + ", " + item.DateTimeReceived.Date.ToString("dd/MM/yyyy"));
}
else
{
//handle error log here
}
}
return returnItems;
}
I just did a similiar thing. However, I was unable to get the list of contacts via Exchange since that only gets users that have mailboxes, and not necessarily all users or groups. I eventually ended up getting all the users via AD
here is code to get all the contacts in AD. All you need is the folderID of the global address list which can be gotten from using the ADSI.msc tool on your AD server and browsing to the Global address list folder, look at properties and grab the value of the "purported search". In my system the searchPath for the global address list is"(&(objectClass=user)(objectCategory=person)(mailNickname=)(msExchHomeServerName=))"
public List<ListItem> SearchAD(string keyword, XmlDocument valueXml)
{
List<ListItem> ewsItems = new List<ListItem>();
using (DirectoryEntry ad = Utils.GetNewDirectoryEntry("LDAP://yourdomain.com"))
{
Trace.Info("searcherをつくる");
using (DirectorySearcher searcher = new DirectorySearcher(ad))
{
if (this.EnableSizeLimit)
{
searcher.SizeLimit = GetMaxResultCount();
if (Utils.maxResultsCount > 1000)
{
searcher.PageSize = 100;
}
}
else
{
searcher.SizeLimit = 1000;
searcher.PageSize = 10;
}
string sisya = Utils.DecodeXml(valueXml.SelectSingleNode("Folder/SearchPath").InnerText); //this is the folder to grab your contacts from. In your case Global Address list
//Container
if(String.IsNullOrEmpty(sisya))
{
return null;
}
keyword = Utils.EncodeLdap(keyword);
string text = Utils.DecodeXml(valueXml.SelectSingleNode("Folder/Text").InnerText);
searcher.Filter = this.CreateFilter(keyword, sisya);
searcher.Sort = new SortOption("DisplayName", System.DirectoryServices.SortDirection.Ascending);
//一つのPropertyをロードすると、全Propertyを取らないようになる
searcher.PropertiesToLoad.Add("SAMAccountName"); //どのPropertyでもいい。
SearchResultCollection searchResults = searcher.FindAll();
foreach (SearchResult searchResult in searchResults)
{
//ListItem contact = null;
using (DirectoryEntry userEntry = searchResult.GetDirectoryEntry())

try
{
string schemaClassName = userEntry.SchemaClassName;
