How to handle null as a key value in Hashtable in blackberry? - blackberry

As, I know Hash table doesn't allow null.
How to handle it if I want to put key pair values?
Is there any other alternative in blackberry ??

You can extend Hashtable with something like this
class NullKeyHashtable extends Hashtable {
private static Object NULL = new Object();
private Object nullToNull(Object key) {
return key == null ? NULL : key;
}
public Object put(Object key, Object value) {
return super.put(nullToNull(key), value);
}
public Object get(Object key) {
return super.get(nullToNull(key));
}
...
}

How to save and read Cookie in Asp.net Mvc

I save my cookie as the following code:
public static void SetCookie(string key, string value, int expireDay = 1)
{
var cookie = new HttpCookie(key , value);
cookie.Expires = DateTime.Now.AddDays(expireDay);
HttpContext.Current.Response.Cookies.Add(cookie);
}
The cookie values when stored are as follows:
Read Cookie:
public static string GetCookie(string key)
{
string value = string.Empty;
var cookie = HttpContext.Current.Request.Cookies[key];
if (cookie != null)
{
if (string.IsNullOrWhiteSpace(cookie.Value))
{
return value;
}
value = cookie.Value;
}
return value;
}
The problem is that when reading the cookie, all the values are empty according to the image below:
The maximum size of a cookie is 4kb.
Actually you should read cookies from request header; not response!
The problem is here: HttpContext.Current.Response.Cookies.AllKeys.Contains(key).
You need to read it from the request. And write the changes to the response.
Here's a simpler working example, that simply prints "Hey!", and appends an exclamation on each GET:
public class IndexModel : PageModel
{
public string CookieValue = "Hey!";
private const string COOKIE_KEY = "HEY_COOKIE";
public void OnGet()
{
Request.Cookies.TryGetValue(COOKIE_KEY, out string? actualValue);
if (actualValue is not null) CookieValue = actualValue + "!";
// Only required since we're changing the cookie
// TODO: set the right cookie options
Response.Cookies.Append(COOKIE_KEY, CookieValue, new CookieOptions { });
}
}
#page
#model IndexModel
<h1>#Model.CookieValue</h1>
Also, while debugging things over HTTP, it's useful to also look at Chrome's network tab.
Your problem is that you used HttpContext.Current.Response. Instead of this, you should declare a parameter in the SetCookie method like this: HttpContext context, then in the controller, when you call the method, you have to send HttpContext controller property as an argument.
public static void SetCookie(HttpContext context, string key, string value, int expireDay = 1)
{
var cookie = new HttpCookie(key , value);
cookie.Expires = DateTime.Now.AddDays(expireDay);
context.Response.Cookies.Add(cookie);
}
In the controller:
SetCookie(HttpContext, yourKey,yourValue)
You also should change your GetCookie method like this:
public static string GetCookie(HttpContext context,string key)
{
string value = string.Empty;
var cookie = context.Request.Cookies[key];
if (cookie != null)
{
if (string.IsNullOrWhiteSpace(cookie.Value))
{
return value;
}
value = cookie.Value;
}
return value;
}

Original data changed after using modified JsonValueProviderFactory to solve maxJsonLength exception

I'm working with some application designed using ASP.NET MVC.
Did spend lot of time trying to solve some problem, but do not have idea what to do to solve it.
As similar code shown below for big JSON will throw exception :
"Error during serialization or deserialization using the JSON JavaScriptSerializer. The length of the string exceeds the value set on the maxJsonLength property.
"
EXAMPLE :
$http.post('/API/PostData',aoData)...
where aoData equals 3K array of JSON, etc.
Added some solution suggested in many questions being asked on stackoverflow.
Did solve that problem just by :
Removing JsonValueProviderFactory from the ValueProviderFactories.Factories
And adding copy of the original class with simple modification such as :
EXAMPLE:
public sealed class LargeJsonValueProviderFactory : ValueProviderFactory
{
private static void AddToBackingStore(LargeJsonValueProviderFactory.EntryLimitedDictionary backingStore, string prefix, object value)
{
IDictionary<string, object> dictionary = value as IDictionary<string, object>;
if (dictionary != null)
{
foreach (KeyValuePair<string, object> keyValuePair in (IEnumerable<KeyValuePair<string, object>>) dictionary)
LargeJsonValueProviderFactory.AddToBackingStore(backingStore, LargeJsonValueProviderFactory.MakePropertyKey(prefix, keyValuePair.Key), keyValuePair.Value);
}
else
{
IList list = value as IList;
if (list != null)
{
for (int index = 0; index < list.Count; ++index)
LargeJsonValueProviderFactory.AddToBackingStore(backingStore, LargeJsonValueProviderFactory.MakeArrayKey(prefix, index), list[index]);
}
else
backingStore.Add(prefix, value);
}
}
private static object GetDeserializedObject(ControllerContext controllerContext)
{
if (!controllerContext.HttpContext.Request.ContentType.StartsWith("application/json", StringComparison.OrdinalIgnoreCase))
return (object) null;
string end = new StreamReader(controllerContext.HttpContext.Request.InputStream).ReadToEnd();
if (string.IsNullOrEmpty(end))
return (object) null;
var serializer = new JavaScriptSerializer {MaxJsonLength = Int32.MaxValue};
return serializer.DeserializeObject(end);
}
/// <summary>Returns a JSON value-provider object for the specified controller context.</summary>
/// <returns>A JSON value-provider object for the specified controller context.</returns>
/// <param name="controllerContext">The controller context.</param>
public override IValueProvider GetValueProvider(ControllerContext controllerContext)
{
if (controllerContext == null)
throw new ArgumentNullException("controllerContext");
object deserializedObject = LargeJsonValueProviderFactory.GetDeserializedObject(controllerContext);
if (deserializedObject == null)
return (IValueProvider) null;
Dictionary<string, object> dictionary = new Dictionary<string, object>((IEqualityComparer<string>) StringComparer.OrdinalIgnoreCase);
LargeJsonValueProviderFactory.AddToBackingStore(new LargeJsonValueProviderFactory.EntryLimitedDictionary((IDictionary<string, object>) dictionary), string.Empty, deserializedObject);
return (IValueProvider) new DictionaryValueProvider<object>((IDictionary<string, object>) dictionary, CultureInfo.CurrentCulture);
}
private static string MakeArrayKey(string prefix, int index)
{
return prefix + "[" + index.ToString((IFormatProvider) CultureInfo.InvariantCulture) + "]";
}
private static string MakePropertyKey(string prefix, string propertyName)
{
if (!string.IsNullOrEmpty(prefix))
return prefix + "." + propertyName;
return propertyName;
}
private class EntryLimitedDictionary
{
private static int _maximumDepth = LargeJsonValueProviderFactory.EntryLimitedDictionary.GetMaximumDepth();
private readonly IDictionary<string, object> _innerDictionary;
private int _itemCount;
public EntryLimitedDictionary(IDictionary<string, object> innerDictionary)
{
this._innerDictionary = innerDictionary;
}
public void Add(string key, object value)
{
if (++this._itemCount > LargeJsonValueProviderFactory.EntryLimitedDictionary._maximumDepth)
throw new InvalidOperationException("JsonValueProviderFactory_RequestTooLarge");
this._innerDictionary.Add(key, value);
}
private static int GetMaximumDepth()
{
NameValueCollection appSettings = ConfigurationManager.AppSettings;
if (appSettings != null)
{
string[] values = appSettings.GetValues("aspnet:MaxJsonDeserializerMembers");
int result;
if (values != null && values.Length > 0 && int.TryParse(values[0], out result))
return result;
}
return 1000;
}
}
}
And that solve the problem with maxJsonLength. Great! But...
If JSON contains property called ACTION, controller get data being changed. The ACTION property contains name of the controller's action instead of "MAR". The LargeJsonValueProviderFactory class does not change value of the ACION property. But if LargeJsonValueProviderFactory class shown above is not is use issue disappears.
EXAMPLE :
{
NR : 1200,
ACTION : "MAR",
.....
}
public ActionResult Save(PrsentationEntity aoData)
{
aoData.NR equals 1200 - OK
aoData.ACTION equals "Save" -Should be "MAR"
Do you have any ideas why I have that problem ?
Regards
Marcin
tl;dr
When configuring the application the original JsonValueProviderFactory should be replaced by the custom LargeJsonValueProviderFactory instead of added to the end of the collection.
Long version
You said you solved the problem by:
Removing JsonValueProviderFactory from the ValueProviderFactories.Factories
And adding copy of the original class with simple modification such as :
That's why the problem occurs.
The order of the factories on ValueProviderFactories.Factories does matter, but it's not generally discussed.
The original order is this:
private static readonly ValueProviderFactoryCollection _factories = new ValueProviderFactoryCollection()
{
new ChildActionValueProviderFactory(),
new FormValueProviderFactory(),
new JsonValueProviderFactory(),
new RouteDataValueProviderFactory(),
new QueryStringValueProviderFactory(),
new HttpFileCollectionValueProviderFactory(),
new JQueryFormValueProviderFactory()
};
If you just add your new provider to the end of the collection it won't be used if one of the other providers does the job (in this case it seems that RouteDataValueProviderFactory was used).

Adapt field to store to database

Say I have a field content that is a json. I would like to store it in database so that my domain class keeps only the 1 field only. (It's more of a brain task ;-)
class MyDomain{
def content
static constraints = {
content nullable: false, blank: false, sqlType: "text" // adapter from JSON to String??
}
def beforeInsert(){
content = content.toString()
}
def beforeUpdate(){
content = content.toString()
}
def afterInsert(){
content = JSON.parse(content) as JSON
}
def afterUpdate(){
content = JSON.parse(content) as JSON
}
def onLoad(){
content = JSON.parse(content) as JSON
}
}
I want my domain object to expose only content so I don't want to use another field like String contentAsText because it would be visible outside.
In the whole GORM documentation I haven't found a thing how to manage it. I've tried beforeValidate()/beforeInsert() and onLoad() methods but no luck...
How can I adapt the value before it gets persisted?
You can define a custom hibernate user-type for JSONElement as described here: https://stackoverflow.com/a/28655708/607038
In domain class constraints:
static constraints = {
content type: JSONObjectUserType
}
User Type Class:

class JSONObjectUserType implements EnhancedUserType, Serializable {

#Override

}
#Override

}
#Override
public boolean equals(Object x, Object y) throws HibernateException {
if (x == y) {
return true
}
if (x == null || y == null) {
return false
}
JSONObject zx = (JSONObject) x
JSONObject zy = (JSONObject) y
return zx.equals(zy)
}
#Override
public int hashCode(Object object) throws HibernateException {
return object.hashCode()
}
#Override
public Object nullSafeGet(ResultSet resultSet, String[] names, SessionImplementor session, Object owner)
throws HibernateException, SQLException {
Object jsonObject = StandardBasicTypes.STRING.nullSafeGet(resultSet, names, session, owner)
if (jsonObject == null) {
return null
}
return new JSONObject((String) jsonObject)
}
#Override
public void nullSafeSet(PreparedStatement preparedStatement, Object value, int index, SessionImplementor session)
throws HibernateException, SQLException {
if (value == null) {
StandardBasicTypes.STRING.nullSafeSet(preparedStatement, null, index, session)
} else {
JSONObject jsonObject = (JSONObject) value
StandardBasicTypes.STRING.nullSafeSet(preparedStatement, jsonObject.toString(), index, session)
}
}
#Override
public Object deepCopy(Object value) throws HibernateException {
return value
}
#Override
public boolean isMutable() {
return false
}
#Override
public Serializable disassemble(Object value) throws HibernateException {
return (Serializable) value
}
#Override
public Object assemble(Serializable cached, Object value) throws HibernateException {
return cached
}
#Override
public Object replace(Object original, Object target, Object owner) throws HibernateException {
return original
}
#Override
public String objectToSQLString(Object object) {
throw new UnsupportedOperationException()
}
#Override
public String toXMLString(Object object) {
return object.toString()
}
#Override
public Object fromXMLString(String string) {
return new JSONObject(string)
}
}
class MyDomain{
JSONElement content
static constraints = {
content nullable: false, blank: false, sqlType: "text" // adapter from Map to String??
}
def setContent(String textContent){
content = JSON.parse(textContent)
}
}
I had to do 2 things.
replace def content with JSON content so that it gets persisted, see Grails Domain Constructor is not Groovy Constructor
Convert a json string back to json via def setContent().
As content is JSONElement use JSONObject and JSONArray as concrete classes.

MVC 5 Entity Framework 6 Execute Stored Procedure

I'm stuck. I have an existing application with an extremely large database and extensive library of stored procedures and functions. All I want to do is use a DbContext to execute a stored procedure and return a set of data or map to one of the entities in the context. Is that something magical I haven't discovered on the net somewhere? Someone, anyone, please help. Here's what I've got so far (and it doesn't return anything, the result is -1):
var contacts = db.Database.ExecuteSqlCommand("Contact_Search #LastName, #FirstName",
new SqlParameter("#LastName", GetDataValue(args.LastName)),
new SqlParameter("#FirstName", GetDataValue(args.FirstName)));
Executing that returns -1. I also tried something to the effect of this with no success:
DbRawSqlQuery<Contact> data = db.Database.SqlQuery<Contact>
("EXEC Contact_Search #LastName, #FirstName",
GetDataValue(args.LastName),
GetDataValue(args.FirstName));
I understand that I could add an edmx and map to a stored procedure that way, but that is not the preferred method. Again, our database contains nearly 450 million records and a library of almost 3,000 stored procedures and functions. It would be a nightmare to maintain. Am I even starting in the right direction? Is Entity Framework the right choice?
Wow, it seems right after I give up, I somehow stumble upon the answer. I found a FANTASTIC post about executing stored procedures and after reading up, this was my solution:
var contacts = db.Database.SqlQuery<Contact>("Contact_Search #LastName, #FirstName",
So, many thanks to Anuraj for his excellent post! The key to my solution was to first use SqlQuery instead of ExecuteSqlCommand, and also to execute the method mapping to my entity model (Contact).
This code is better than SqlQuery() because SqlQuery() doesn't recognise the [Column] attribute.
Here it is on a silver platter.

Grails, property names in embedded object in domain class causing problems

I'm using grails 2.3.4 and I have a domain class that embeds an object. The embedded object has a property called 'version' and it seems that this is conflicting with the 'version'-field automatically added to the database-table by GORM. The result is that the 'version'-field belonging to my embedded object isn't created in the database and as a consequence my application doesn't work properly.
My code looks like this:
class Thing {
String someText
EmbeddedThing embeddedThing
Date someDate
static embedded = ['embeddedThing']
static constraints = {
embeddedThing(unique: true)
}
}
class EmbeddedThing {
String textOfSomeSort
String version
String textOfSomeOtherSort
}
You might think that a quick fix is to rename the 'version'-property of the embedded object but the class belongs to an included sub-project (i.e. a JAR-file) that I'm not allowed to touch since other projects use it. So the solution needs to be done completely within my domain class, or at least in a manner that doesn't change the class of the embedded object.
version is a special column name, you should rename your version field within your EmbeddedThin class
I actually found a solution to this problem by using a Hibernate UserType to represent the EmbeddedThing-class.
My code now looks like this and works perfectly:
Thing.groovy:
import EmbeddedThingUserType
class Thing {
String someText
EmbeddedThing embeddedThing
Date someDate
static embedded = ['embeddedThing']
static mapping = {
version false
embeddedThing type: EmbeddedThingUserType, {
column name: "embedded_thing_text"
column name: "embedded_thing_version"
column name: "embedded_thing_other_text"
}
}
static constraints = {
embeddedThing(unique: true)
}
}
EmbeddedThing.groovy:
class EmbeddedThing {
String textOfSomeSort
String version
String textOfSomeOtherSort
}
EmbeddedThingUserType.groovy:
class EmbeddedThingUserType implements UserType {
int[] sqlTypes() {
return [StringType.INSTANCE.sqlType(),
StringType.INSTANCE.sqlType(),
StringType.INSTANCE.sqlType()]
}
Class returnedClass() {
return EmbeddedThing
}
public Object nullSafeGet(ResultSet resultSet, String[] names, Object owner)
throws HibernateException, SQLException {
if (resultSet && names) {
return new EmbeddedThing(
textOfSomeSort: resultSet?.getString(names[0] ?: '_missing_textOfSomeSort_'),
version: resultSet?.getString(names[1] ?: '_missing_version_'),
textOfSomeOtherSort: resultSet?.getString(names[2] ?: '_missing_textOfSomeOtherSort_'))
} else {
return null
}
}
public void nullSafeSet(PreparedStatement preparedStatement, Object value, int index)
throws HibernateException, SQLException {
if (value != null) {
preparedStatement.setString(index, value?.textOfSomeSort)
preparedStatement.setString(index + 1, value?.version)
preparedStatement.setString(index + 2, value?.textOfSomeOtherSort)
} else {
preparedStatement.setString(index, '_missing_textOfSomeSort_')
preparedStatement.setString(index + 1, '_missing_version_')
preparedStatement.setString(index + 2, '_missing_textOfSomeOtherSort_')
}
}

Please try version false in your 'static mapping', for the 'EmbeddedThing' class.
