LINQ to SQL submitchanges not doing anything - c#

My issue is the following: i'm trying to build a function to which i could pass a list of items, which would then go to the db with each of those items and update them. I believe the issue is within the way datacontexts are being used but i cannot figure out this issue.
Here is my function that builds the list of items that were changed:
protected void btnSave_Click(object sender, EventArgs e)
{
List<AFF_CMS_FMA> fmasToSave = new List<AFF_CMS_FMA>();
AFF_CMS_FMA newFmaItem = new AFF_CMS_FMA();
foreach (AFF_CMS_FMA fmaItem in FmaLib.fetchAllActiveAssetsInFMA())
{
if (fmaItem.SortOrder != Convert.ToInt32(Request.Form["fmaItem_" + fmaItem.ID + "_SortOrder"]))
{
newFmaItem = fmaItem;
newFmaItem.Name = SecurityLib.SqlSafeString(Request.Form["fmaItem_" + fmaItem.ID + "_Name"]);
newFmaItem.AssetID = Convert.ToInt32(Request.Form["fmaItem_" + fmaItem.ID + "_AssetID"]);
newFmaItem.SortOrder = Convert.ToInt32(Request.Form["fmaItem_" + fmaItem.ID + "_SortOrder"]);
newFmaItem.ImagePathEn = SecurityLib.SqlSafeString(Request.Form["fmaItem_" + fmaItem.ID + "_ImagePathEn"]);
newFmaItem.ImagePathCh = SecurityLib.SqlSafeString(Request.Form["fmaItem_" + fmaItem.ID + "_ImagePathCh"]);
newFmaItem.StartDate = DateTime.Parse(SecurityLib.SqlSafeString(Request.Form["fmaItem_" + fmaItem.ID + "_StartDate"]));
newFmaItem.EndDate = DateTime.Parse(SecurityLib.SqlSafeString(Request.Form["fmaItem_" + fmaItem.ID + "_EndDate"]));
newFmaItem.ClickToUrl = SecurityLib.SqlSafeString(Request.Form["fmaItem_" + fmaItem.ID + "_ClickToUrl"]);
fmasToSave.Add(newFmaItem);
}
}
FmaLib.saveEditedFmas(fmasToSave);
}
here is the function that the foreach loops calls to get all the items that are in the db:
public static List<AFF_CMS_FMA> fetchAllActiveAssetsInFMA()
{
List<AFF_CMS_FMA> results = null;
using (fmaDataContext db = new fmaDataContext())
{
using (TransactionScope ts = new TransactionScope())
{
try
{
if (HttpContext.Current.Cache["fmaActiveList"] == null)
{
db.LoadOptions = loadAll;
results = clsCompiledQuery.getAllActiveFmas(db).ToList();
HttpContext.Current.Cache["fmaActiveList"] = results;
}
else
results = (List<AFF_CMS_FMA>)HttpContext.Current.Cache["fmaActiveList"];
ts.Complete();
}
catch (Exception ex)
{ Transaction.Current.Rollback(); }
}
return results;
}
}
here are the queries being used:
protected static class clsCompiledQuery
{
public static Func<DataContext, IOrderedQueryable<AFF_CMS_FMA>>
getAllActiveFmas = CompiledQuery.Compile((DataContext db)
=> from fma in db.GetTable<AFF_CMS_FMA>()
where fma.IsArchived == false
orderby fma.SortOrder ascending
select fma);
public static Func<DataContext, int,IQueryable<AFF_CMS_FMA>>
getFmaById = CompiledQuery.Compile((DataContext db, int ID)
=> from fma in db.GetTable<AFF_CMS_FMA>()
where fma.ID == ID
select fma);
}
and finally this were im trying to get the save to happen to the db but no exeptions are throwns, yet the db does not change
public static bool saveEditedFmas(List<AFF_CMS_FMA> fmaToSaveList)
{
using (fmaDataContext db = new fmaDataContext())
{
using (TransactionScope ts = new TransactionScope())
{
try
{
foreach (AFF_CMS_FMA fmaItemToSave in fmaToSaveList)
{
AFF_CMS_FMA fmaItemToUpdate = clsCompiledQuery.getFmaById(db, fmaItemToSave.ID).ToList()[0];
fmaItemToUpdate = fmaItemToSave;
db.SubmitChanges();
}
return true;
}
catch (Exception ex)
{
Transaction.Current.Rollback();
return false;
}
}
}
}
I have checked and the table does contain a primary key in the designer. If i do the save from the btnSave_click function by passing a datacontext to the fetchAllActiveAssetsInFMA() then doing submitchanges on that context it works .. but im trying to abstract that from there.
thanks all in advance

Your not calling ts.Complete in function saveEditedFmas.
Also I would recommend calling db.SubmitChanges(); outside of the for loop. And why do you have a transaction in function fetchAllActiveAssetsInFMA? It's only fetching data right? And I'm not quite sure whats happening inside the for loop in save function, looks strange.
I think you should map the properties from fmaItemToSave to fmaItemToUpdate
foreach (var fmaItemToSave in fmaToSaveList)
{
var fmaItemToUpdate = clsCompiledQuery.getFmaById(db, fmaItemToSave.ID).First();
fmaItemToUpdate.Name = fmaItemToSave.Name;
fmaItemToUpdate.AssetID = fmaItemToSave.AssetID;
//And the rest of the properties
}
db.SubmitChanges();

Why does select from sqlite db shows error 'Specified cast is not valid.' in Xamarin Forms?

Getting a single value from by SQLite database but I get the error System.InvalidCastException: 'Specified cast is not valid.'
I need only the first value of the select results, tried both First() and ElementAtOrDefault(0) but same thing happens.
Error gets catched when trying to assing to the variable IDPromoMainPage, not before.
Basically this is how I call the value:
private void GetPromoLocal()
{
try
{
var databasePath = System.IO.Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Personal), "LocalDB.db3");
var db = new SQLiteConnection(databasePath);
IEnumerable<T_Promo> resultado = SELECT_WHERE(db);
if (resultado.Count() > 0)
{
IDPromoMainPage = Convert.ToInt32(resultado.First()); // ElementAtOrDefault(0));
}
}
catch (Exception)
{
throw;
}
}
public static IEnumerable<T_Promo> SELECT_WHERE(SQLiteConnection db)
{
return db.Query<T_Promo>("SELECT IDPromo FROM T_Promo");
}
Also have the same error happening here, exactly at line "PisterosLista = resultado.Cast().ToList();"
List<Pisteros> PisterosLista = new List<Pisteros>();
public void GetPisterosLocal()
{
try
{
var databasePath = System.IO.Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Personal), "LocalDB.db3");
var db = new SQLiteConnection(databasePath);
IEnumerable<T_Pisteros> resultado = SELECT_WHERE_Pist(db);
if (resultado.Count() > 0)
{
PisterosLista = resultado.Cast<Pisteros>().ToList();
//Console.WriteLine("content :: " + content);
Console.WriteLine("Data :: " + PisterosLista);
}
}
catch (Exception)
{
throw;
}
}
public static IEnumerable<T_Pisteros> SELECT_WHERE_Pist(SQLiteConnection db)
{
return db.Query<T_Pisteros>("SELECT * FROM T_Pisteros");
}
if the column IDPromo is an int, then just do this
IEnumerable<int> resultado = SELECT_WHERE(db);
public static IEnumerable<int> SELECT_WHERE(SQLiteConnection db)
{
return db.Query<int>("SELECT IDPromo FROM T_Promo");
}

SQLite table doesn't get updated

I have a problem. I created a SwitchButton and want to store the state in a database table. So I created this code to debug:
SettingSwitch.CheckedChange += (s, b) =>
{
SettingDb testsetting = new SettingDb
{
Name = mItems[position].Name,
};
SettingDb test = MainActivity.db.SelectRowFromTableSettings(testsetting);
if (test != null)
{
bool SwitchValueBool = Convert.ToBoolean(test.Value);
}
bool isChecked = ValueDictionary[position];
if(isChecked == true)
{
isChecked = false;
}
else if(isChecked == false)
{
isChecked = true;
}
SettingDb setting = new SettingDb()
{
Name = SettingName.Text,
Type = "Switch",
Value = isChecked.ToString()
};
MainActivity.db.UpdateTableSettings(setting);
ValueDictionary[position] = isChecked;
SettingDb test2 = MainActivity.db.SelectRowFromTableSettings(testsetting);
if (test2 != null)
{
bool SwitchValueBool = Convert.ToBoolean(test2.Value);
}
};
The expected outcome should be:
test.Value = False
test2.Value = Opposite of test.Value, so True
But now the value I get from the table is always False. Here is the update function:
string folder = System.Environment.GetFolderPath(System.Environment.SpecialFolder.Personal);
public bool UpdateTableSettings(SettingDb setting)
{
try
{
using (var connection = new SQLiteConnection(System.IO.Path.Combine(folder, "Settings.db")))
{
connection.BeginTransaction();
connection.Query<SettingDb>("UPDATE SettingDb SET Value=? WHERE Name=?", setting.Value, setting.Name);
//connection.Update(setting);
connection.Commit();
return true;
}
}
catch (SQLiteException ex)
{
Log.Info("SQLiteEx", ex.Message);
return false;
}
}
public SettingDb SelectRowFromTableSettings(SettingDb setting)
{
try
{
using (var connection = new SQLiteConnection(System.IO.Path.Combine(folder, "Settings.db")))
{
return connection.Query<SettingDb>("SELECT * FROM SettingDb WHERE Name=?", setting.Name).FirstOrDefault();
}
}
catch (SQLiteException ex)
{
Log.Info("SQLiteEx", ex.Message);
return null;
}
}
The table value doesn't get updated!!!
Can someone tell me what I am doing wrong?
Please let me know!
According to your description, you want to update sqlite database table, please take a look the following code and modify the update function.
static void UpdateDatabase(int primaryKey, string newText, int newValue)
{
string path = Path.Combine(System.Environment.GetFolderPath(System.Environment.SpecialFolder.MyDocuments), "mydatabase.db");
var db = new SQLiteConnection(path, false);
string sql = "UPDATE MyTable SET MyTextColumn = ?, MyValueColumn = ? WHERE MyPrimaryKey= ?";
string[] parms = new String[] { newText, newValue.ToString(), primaryKey.ToString() };
var cmd = db.CreateCommand(sql, parms);
cmd.ExecuteNonQuery();
}

System.Data.Entity.Validation.DbEntityValidationException

I have a project that uses Entity Framework. While calling SaveChanges on my DbEntityValidationException, I get the following exception:
System.Data.Entity.Validation.DbEntityValidationException: 'Validation
failed for one or more entities. See 'EntityValidationErrors' property
for more details.'
This is all fine and dandy, but I don't want to attach a debugger every time this exception occurs. More over, in production environments I cannot easily attach a debugger so I have to go to great lengths to reproduce these errors.
How can I see the details hidden within the DbEntityValidationException?

You have to get the validation errors from the db.SaveChanges() method of the DatabaseContext object -- you can't get them where you are.
You can either modify the SaveChanges() method of your database context and wrap it in a try-catch block, or (since the class is partial) you can extend the partial class within your application and just override the SaveChanges() method.
There is a nice blog post about this called Easy way to improve DbEntityValidationException of Entity Framework here.
The essence of it is something like this:
public partial class NorthwindEntities
{
public override int SaveChanges()
{
try
{
return base.SaveChanges();
}
catch (DbEntityValidationException ex)
{
// Retrieve the error messages as a list of strings.
var errorMessages = ex.EntityValidationErrors
.SelectMany(x => x.ValidationErrors)
.Select(x => x.ErrorMessage);
// Join the list to a single string.
var fullErrorMessage = string.Join("; ", errorMessages);
// Combine the original exception message with the new one.
var exceptionMessage = string.Concat(ex.Message, " The validation errors are: ", fullErrorMessage);
// Throw a new DbEntityValidationException with the improved exception message.
throw new DbEntityValidationException(exceptionMessage, ex.EntityValidationErrors);
}
}
}
The blogger explains:
That’s it! The rest of your code will automatically use the overridden
SaveChanges so you don’t have to change anything else. From now on,
your exceptions will look like this:
System.Data.Entity.Validation.DbEntityValidationException: Validation
failed for one or more entities. See 'EntityValidationErrors' property
for more details. The validation errors are: The field PhoneNumber
must be a string or array type with a maximum length of '12'; The
LastName field is required.
The DbEntityValidationException also contains the entities that caused
the validation errors. So if you require even more information, you
can change the above code to output information about these entities.
As mention, you need to check on your EntityValidationError when it throws the exception.
You should fix that validation error, instead of asking bypass this exception.
Normally these errors are table allow length, data type, column does not allow null and etc. There will be exact fiend name mention in your exception too.

Thread abort in Window Service in C#

I have a window Service which converts the PDF file to html and it is running in 5 threads.
Each thread picks the record from database where status is 0.Once it picks the record from database we are making the status to 64 and making an entry in log file so that other thread should not pick the same record,after successful conversion we are making the status to 256 if any exception we are making the stratus to 128.
Some records are updated to 64 with out any entry in log and they are not even processed further.
Below is the Stored Procedure to pick the single record from database.
Create PROCEDURE [SGZ].[p_GetNextRequestForProcessing]
#InstanceId int
AS
BEGIN
SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED;
set nocount on
Declare #RequestID bigint = null;
SET #RequestID= (
Select
TOP(1) RequestID
From
sgz.PDFTransformationQueue
Where
RequestStatusID=0
);
If (#RequestID is not null)
BEGIN
Begin Transaction;
Update
sgz.PDFTransformationQueue
SET
RequestStatusid=64,
ProcessedInstanceID =#InstanceId,
ProcessStartTime = getutcdate(),
ModifiedDate=getutcdate()
Where
RequestID=#RequestID and
RequestStatusid =0 and
ProcessedInstanceID is null;
if ##rowcount = 0
set #RequestID=null;
Commit Transaction;
END
Select
RQ.VersionNumber,RQ.RequestID, RP.Payload
From
SGZ.RequestPayload RP WITH (NOLOCK),
SGZ.PDFTransformationQueue RQ WITH (NOLOCK)
Where
RP.RequestId=RQ.RequestID AND
ProcessedInstanceID=#InstanceId AND
RequestStatusid =64 AND
RQ.RequestId = #RequestID;
END
And below is the window service code:-
protected override void OnStart(string[] args)
{
PDFTransAutoProcessManager pdfTransAutoProcessManager = new
PDFTransAutoProcessManager();
pdfTransAutoProcessManager.OnProcessStart();
}
And PDFTransAutoProcessManager class:-
private int _runningAsyncThread = 0;
private int _totalAsynThread = 5;
public void OnProcessStart()
{
_logMgr.Info("Process started # " + DateTime.Now);
mainThread = new Thread(new ThreadStart(StartAutoProcess));
mainThread.Priority = ThreadPriority.Highest;
mainThread.Start();
}
private void StartAutoProcess()
{
try
{
while (true)
{
if (_runningAsyncThread < _totalAsynThread)
{
Thread childThread = new Thread(() => ProcessAsync());
Interlocked.Increment(ref _runningAsyncThread);
childThread.Start();
}
Thread.Sleep(100);
}
}
catch (Exception ex)
{ }
}
private void ProcessAsync()
{
try

}
catch (Exception ex)
{
_logMgr.Info(ex.Message);
_logMgr.Info(ex.StackTrace);
}
finally
{
Interlocked.Decrement(ref _runningAsyncThread);
}
}
And in PDFGenieManager Class actual database call and conversion will happen.
When it is trying to get records from database some records are updated to 64 with out any entry in log.
Is it related to threading pattern or any problem with stored procedure.
Kindly help thanks in advance.

Retrieving user attributes from Active Directory using LDAP - JAVA

EDIT: I've posted the solution below.
I know you don't like these type of questions, but i've been struggling with this issue for half a day now.
I've written a C# code that fetches user attributes from our Active Directory using LDAP, the code works well.
The code is as follows:
DirectoryEntry dirEnt = new DirectoryEntry("LDAP://dc=dom,dc=int");
DirectorySearcher adSearch = new DirectorySearcher(dirEnt);
adSearch.SearchScope = SearchScope.Subtree;
adSearch.PageSize = 10000;
adSearch.Filter = "(&(objectClass=user))";
SearchResultCollection sColl = adSearch.FindAll();
foreach (SearchResult sResult in sColl)
{
string sConn = sResult.Properties["distinguishedName"][0].ToString();
DirectoryEntry dirEnt2 = new DirectoryEntry("LDAP://" + sConn);
...
// dirEnt2 contains ALL attributes for the user
}
I'm trying to port this code to Java, but it seems like that the technique I used in C# does not work too well in Java.
Using the following code
DirContext context;
ArrayList<String> nList = new ArrayList<String>();
Hashtable env = new Hashtable();
String username = ...;
String password = ...;
try {
env.put(Context.SECURITY_PRINCIPAL, username);
env.put(Context.SECURITY_CREDENTIALS, password);
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, ldapUri);
try {
context = new InitialDirContext(env);
} catch (NamingException e) {
throw new RuntimeException(e);
}
SearchControls ctrl = new SearchControls();
ctrl.setSearchScope(SearchControls.SUBTREE_SCOPE);
NamingEnumeration enumeration = context.search("", "(objectClass=user)",
ctrl);
while (enumeration.hasMore()) {
SearchResult result = (SearchResult) enumeration.next();
Attributes attribs = result.getAttributes();
NamingEnumeration values = ((BasicAttribute)
attribs.get("distinguishedName")).getAll();
while (values.hasMore()) {
nList.add(values.next().toString());
}
}
} catch (NamingException e) {
e.printStackTrace();
}
for (String sVar : nList ){
Hashtable env2 = new Hashtable();
env2.put(Context.SECURITY_PRINCIPAL, username);
env2.put(Context.SECURITY_CREDENTIALS, password);
env2.put(Context.INITIAL_CONTEXT_FACTORY,
"com.sun.jndi.ldap.LdapCtxFactory");
env2.put(Context.PROVIDER_URL, "ldap://DOM/" + sVar);
Attributes attrs = null;
try {
context = new InitialDirContext(env2);
attrs = context.getAttributes(sVar);
} catch (NamingException e) {
System.out.println(e.toString());
continue;
}
System.out.println(attrs.toString());
}
Yields that attrs only contains BASIC attributes regarding the user (such as samaccountname, displayname, etc)
and no 'email', 'telephone' or any other similar attributes.
Any help on the issue is blessed!
Here's the solution, sorry for the messy code/formatting

}

Control[] controls = ctx.getResponseControls();
if (controls != null) {
for (int i = 0; i < controls.length; i++) {
if (controls[i] instanceof PagedResultsResponseControl) {
PagedResultsResponseControl prrc =
(PagedResultsResponseControl)controls[i];
total = prrc.getResultSize();
cookie = prrc.getCookie();
} else {
// Handle other response controls (if any)
}
}
}
// Re-activate paged results
ctx.setRequestControls(new Control[]{
new PagedResultsControl(10000, cookie, Control.CRITICAL) });
} while (cookie != null);
} catch (Exception e) {
e.printStackTrace();
}
}
public static SearchControls getSimpleSearchControls() {
SearchControls searchControls = new SearchControls();
searchControls.setSearchScope(SearchControls.SUBTREE_SCOPE);
searchControls.setTimeLimit(30000);
String[] attrIDs =
{ "SAMAccountName", "sn", "givenname", "employeeID",
"employeeNumber" };
searchControls.setReturningAttributes(attrIDs);
return searchControls;
}
}
Try setting the returned attributes on your SearchControls
ctrl.setReturningAttributes(new String[] {"email", "telephone"});
