My Application requires me to find out whether an incoming email was BCC'd to me or am i the direct(to,cc) recipient.
I have used the SendListener and the Address class but i am still clueless how to get what i need.
Any lead would be appreciated.
Thanks n Cheers
try this
public static String getMyEmailAddress() {
// Shared routine to get this BlackBerry's default email address
String emailAddress;
try {
Session ourSession = Session.getDefaultInstance();
// This returns null if BB does not have a Message Service - which means next
// instruction will get a null pointer exception.
emailAddress = ourSession.getServiceConfiguration().getEmailAddress();
} catch ( Exception e ) {
emailAddress = null;
}
return emailAddress;
}
public static boolean isBCCToME(){
String myEmailAddress =getMyEmailAddress();
Address[] a = msg.getRecipients(Message.RecipientType.BCC);
for (int i = 0; i < a.length; i++) {
if(a[i].equals(myEmailAddress)){
return true;
}
}
return false;
}

Ok so I think I'm being a noob because it's a new semester but the method "palindromeTest" always return's false even though the string is equal and the number is a palindrome. (A palindrome example is: (565) 677-6565) (also don't give me the answer outright I want to solve it on my own)
public class IjazZ_PhoneStringPalindrome
{
public static void main(String[] args) throws IOException
{
String phoneNumber;
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
System.out.print("Enter a phone number in this format (###) ###-####: ");
phoneNumber = br.readLine();
phoneNumber = justNumbers(phoneNumber);
if (palindromeTest(phoneNumber))
{
System.out.println("This phone number is a palindrome!");
}
else
{
System.out.println("This phone number is not a palindrome!");
}
}
public static String justNumbers(String phoneNumber)
{
StringTokenizer st = new StringTokenizer(phoneNumber, " ()-");
StringBuffer number = new StringBuffer();
while(st.hasMoreTokens())
{
number.append(st.nextToken());
}
phoneNumber = number.toString();
return phoneNumber;
}
public static boolean palindromeTest(String pNumber)
{
StringBuffer reversedNumber = new StringBuffer(pNumber);
reversedNumber.reverse().toString();
if(pNumber.equals(reversedNumber))
{
return true;
}
else
{
return false;
}
}
}
You don't assign the value returned by reversedNumber.reverse().toString()to reversedNumber.
Do
String reversedNumberString = reversedNumber.reverse().toString();
And by the way, you can just return
return pNumber.equals(reversedNumber); - the if/else statement is unnecessary.
I am new to the dependency injection pattern and I am having issues getting a new instance of a class from container.Resolve in tinyioc it just keeps returning the same instance rather than a new instance. Now for the code
public abstract class HObjectBase : Object
{
private string _name = String.Empty;
public string Name
{
get
{
return this._name;
}
set
{
if (this._name == string.Empty && value.Length > 0 && value != String.Empty)
this._name = value;
else if (value.Length < 1 && value == String.Empty)
throw new FieldAccessException("Objects names cannot be blank");
else
throw new FieldAccessException("Once the internal name of an object has been set it cannot be changed");
}
}
private Guid _id = new Guid();
public Guid Id
{
get
{
return this._id;
}
set
{
if (this._id == new Guid())
this._id = value;
else
throw new FieldAccessException("Once the internal id of an object has been set it cannot be changed");
}
}
private HObjectBase _parent = null;
public HObjectBase Parent
{
get
{
return this._parent;
}
set
{
if (this._parent == null)
this._parent = value;
else
throw new FieldAccessException("Once the parent of an object has been set it cannot be changed");
}
}
}
public abstract class HZoneBase : HObjectBase
{
public new HObjectBase Parent
{
get
{
return base.Parent;
}
set
{
if (value == null || value.GetType() == typeof(HZoneBase))
{
base.Parent = value;
}
else
{
throw new FieldAccessException("Zones may only have other zones as parents");
}
}
}
private IHMetaDataStore _store;
public HZoneBase(IHMetaDataStore store)
{
this._store = store;
}
public void Save()
{
this._store.SaveZone(this);
}
}
And the derived class is a dummy at the moment but here it is
public class HZone : HZoneBase
{
public HZone(IHMetaDataStore store)
: base(store)
{
}
}
Now since this is meant to be an external library I have a faced class for accessing
everything
public class Hadrian
{
private TinyIoCContainer _container;
public Hadrian(IHMetaDataStore store)
{
this._container = new TinyIoCContainer();
this._container.Register(store);
this._container.AutoRegister();
}
public HZoneBase NewZone()
{
return _container.Resolve<HZoneBase>();
}
public HZoneBase GetZone(Guid id)
{
var metadataStore = this._container.Resolve<IHMetaDataStore>();
return metadataStore.GetZone(id);
}
public List<HZoneBase> ListRootZones()
{
var metadataStore = this._container.Resolve<IHMetaDataStore>();
return metadataStore.ListRootZones();
}
}
However the test is failing because the GetNewZone() method on the Hadrian class keeps returning the same instance.
Test Code
[Fact]
public void ListZones()
{
Hadrian instance = new Hadrian(new MemoryMetaDataStore());
Guid[] guids = { Guid.NewGuid(), Guid.NewGuid(), Guid.NewGuid() };
int cnt = 0;
foreach (Guid guid in guids)
{
HZone zone = (HZone)instance.NewZone();
zone.Id = guids[cnt];
zone.Name = "Testing" + cnt.ToString();
zone.Parent = null;
zone.Save();
cnt++;
}
cnt = 0;
foreach (HZone zone in instance.ListRootZones())
{
Assert.Equal(zone.Id, guids[cnt]);
Assert.Equal(zone.Name, "Testing" + cnt.ToString());
Assert.Equal(zone.Parent, null);
}
}
I know its probably something simple I'm missing with the pattern but I'm not sure, any help would be appreciated.
First, please always simplify the code to what is absolutely necessary to demonstrate the problem, but provide enough that it will actually run; I had to guess what MemoryMetaDataStore does and implement it myself to run the code.
Also, please say where and how stuff fails, to point others straight to the issue. I spent a few minues figuring out that the exception I was getting was your problem and you weren't even getting to the assertions.
That said, container.Resolve<HZoneBase>() will always return the same instance because that's how autoregistration in TinyIoC works - once an abstraction has been resolved, the same instance is always returned for subsequent calls.
To change this, add the following line to the Hadrian constructor:
this._container.Register<HZoneBase, HZone>().AsMultiInstance();
This will tell the container to create a new instance for each resolution request for HZoneBase.
Also, Bassetassen's answer about the Assert part is correct.
In general, if you want to learn DI, you should read Mark Seemann's excellent book "Dependency Injection in .NET" - not quite an easy read as the whole topic is inherently complex, but it's more than worth it and will let you get into it a few years faster than by learning it on your own.
In your assert stage you are not incrementing cnt. You are also using the actual value as the expected one in the assert. This will be confusing, becuase it says something is excpected when it actually is the actual value that is returned.
The assert part should be:
cnt = 0;
foreach (HZone zone in instance.ListRootZones())
{
Assert.Equal(guids[cnt], zone.Id);
Assert.Equal("Testing" + cnt.ToString(), zone.Name);
Assert.Equal(null, zone.Parent);
cnt++;
}
I'm looking for the way to get process id of the application which send SMS. I can get the content of sending message with OutboundMessageListener but I don't know how to get the process id.
Here is my try:
MessageConnection _mc = (MessageConnection) Connector.open("sms://:0");
_mc.setMessageListener(new OutboundSMSListener());
private static final class OutboundSMSListener implements OutboundMessageListener
{
public void notifyIncomingMessage(MessageConnection messageconnection)
{
System.out.println("Incoming message received ");
}
public void notifyOutgoingMessage(Message message)
{
System.out.println("------------------------\n\n\n\n\n");
System.out.println("Message send: " + message);
}
}
Is there any way to do this?
Is the app sending SMS a native app of the BlackBerry device, and does it reside in the foreground?
For getting a foreground application's process id you can use the following code:
private int getForegroungProcessID() {
return ApplicationManager.getApplicationManager().getForegroundProcessId();
}
private String getAppNameByProcessId(int id) {
String result = null;
ApplicationManager appManager = ApplicationManager.getApplicationManager();
ApplicationDescriptor appDes[] = appManager.getVisibleApplications();
for (int i = 0; i < appDes.length; i++) {
if (appManager.getProcessId(appDes[i]) == id) {
result = appDes[i].getModuleName();
//// here check the app name...is it a messaging app ///
break;
}
}
return result;
}
I need to allow my content pipeline extension to use a pattern similar to a factory. I start with a dictionary type:
public delegate T Mapper<T>(MapFactory<T> mf, XElement d);
public class MapFactory<T>
{
Dictionary<string, Mapper<T>> map = new Dictionary<string, Mapper<T>>();
public void Add(string s, Mapper<T> m)
{
map.Add(s, m);
}
public T Get(XElement xe)
{
if (xe == null) throw new ArgumentNullException(
"Invalid document");
var key = xe.Name.ToString();
if (!map.ContainsKey(key)) throw new ArgumentException(
key + " is not a valid key.");
return map[key](this, xe);
}
public IEnumerable<T> GetAll(XElement xe)
{
if (xe == null) throw new ArgumentNullException(
"Invalid document");
foreach (var e in xe.Elements())
{
var val = e.Name.ToString();
if (map.ContainsKey(val))
yield return map[val](this, e);
}
}
}
Here is one type of object I want to store:
public partial class TestContent
{
// Test type
public string title;
// Once test if true
public bool once;
// Parameters
public Dictionary<string, object> args;
public TestContent()
{
title = string.Empty;
args = new Dictionary<string, object>();
}
public TestContent(XElement xe)
{
title = xe.Name.ToString();
args = new Dictionary<string, object>();
xe.ParseAttribute("once", once);
}
}
XElement.ParseAttribute is an extension method that works as one might expect. It returns a boolean that is true if successful.
The issue is that I have many different types of tests, each of which populates the object in a way unique to the specific test. The element name is the key to MapFactory's dictionary. This type of test, while atypical, illustrates my problem.
public class LogicTest : TestBase
{
string opkey;
List<TestBase> items;
public override bool Test(BehaviorArgs args)
{
if (items == null) return false;
if (items.Count == 0) return false;
bool result = items[0].Test(args);
for (int i = 1; i < items.Count; i++)
{
bool other = items[i].Test(args);
switch (opkey)
{
case "And":
result &= other;
if (!result) return false;
break;
case "Or":
result |= other;
if (result) return true;
break;
case "Xor":
result ^= other;
break;
case "Nand":
result = !(result & other);
break;
case "Nor":
result = !(result | other);
break;
default:
result = false;
break;
}
}
return result;
}
public static TestContent Build(MapFactory<TestContent> mf, XElement xe)
{
var result = new TestContent(xe);
string key = "Or";
xe.GetAttribute("op", key);
result.args.Add("key", key);
var names = mf.GetAll(xe).ToList();
if (names.Count() < 2) throw new ArgumentException(
"LogicTest requires at least two entries.");
result.args.Add("items", names);
return result;
}
}
My actual code is more involved as the factory has two dictionaries, one that turns an XElement into a content type to write and another used by the reader to create the actual game objects.
I need to build these factories in code because they map strings to delegates. I have a service that contains several of these factories. The mission is to make these factory classes available to a content processor. Neither the processor itself nor the context it uses as a parameter have any known hooks to attach an IServiceProvider or equivalent.
Any ideas?
I needed to create a data structure essentially on demand without access to the underlying classes as they came from a third party, in this case XNA Game Studio. There is only one way to do this I know of... statically.
public class TestMap : Dictionary<string, string>
{
private static readonly TestMap map = new TestMap();
private TestMap()
{
Add("Logic", "LogicProcessor");
Add("Sequence", "SequenceProcessor");
Add("Key", "KeyProcessor");
Add("KeyVector", "KeyVectorProcessor");
Add("Mouse", "MouseProcessor");
Add("Pad", "PadProcessor");
Add("PadVector", "PadVectorProcessor");
}
public static TestMap Map
{
get { return map; }
}
public IEnumerable<TestContent> Collect(XElement xe, ContentProcessorContext cpc)
{
foreach(var e in xe.Elements().Where(e => ContainsKey(e.Name.ToString())))
{
yield return cpc.Convert<XElement, TestContent>(
e, this[e.Name.ToString()]);
}
}
}
I took this a step further and created content processors for each type of TestBase:
/// <summary>
/// Turns an imported XElement into a TestContent used for a LogicTest
/// </summary>
[ContentProcessor(DisplayName = "LogicProcessor")]
public class LogicProcessor : ContentProcessor<XElement, TestContent>
{
public override TestContent Process(XElement input, ContentProcessorContext context)
{
var result = new TestContent(input);
string key = "Or";
input.GetAttribute("op", key);
result.args.Add("key", key);
var items = TestMap.Map.Collect(input, context);
if (items.Count() < 2) throw new ArgumentNullException(
"LogicProcessor requires at least two items.");
result.args.Add("items", items);
return result;
}
}
Any attempt to reference or access the class such as calling TestMap.Collect will generate the underlying static class if needed. I basically moved the code from LogicTest.Build to the processor. I also carry out any needed validation in the processor.
When I get to reading these classes I will have the ContentService to help.
The scenario of the problem is this
1) We map the struts field values to the dtos. The dtos contain integer fields which again are displayed on the screen.
2) Now I enter an incorrect value which gives conversion error for that integer field.
3) At that point in time I decide to quit the page(i.e press cancel), I get a conversion error. This is because the StrutsConversionErrorInterceptor gets called everytime.
Is there any way that I can skip the strutsConversionErrorInterceptor when I am calling a particular method the way we can skip validation using excludeMethods
Use this code to override Struts's StrutsConversionErrorInterceptor...
public class MyConversionErrorInterceptor extends AbstractInterceptor {
private static final long serialVersionUID = 1L;
public static final String ORIGINAL_PROPERTY_OVERRIDE = "original.property.override";
protected Object getOverrideExpr(ActionInvocation invocation, Object value) {
ValueStack stack = invocation.getStack();
try {
stack.push(value);
return "'" + stack.findValue("top", String.class) + "'";
} finally {
stack.pop();
}
}
#Override
public String intercept(ActionInvocation invocation) throws Exception {
ActionContext invocationContext = invocation.getInvocationContext();
Map<String, Object> conversionErrors = invocationContext.getConversionErrors();
ValueStack stack = invocationContext.getValueStack();
HashMap<Object, Object> fakie = null;
BaseAction baseAction = (BaseAction) invocation.getAction();
String buttonName = baseAction.getButtonName();
for (Map.Entry<String, Object> entry : conversionErrors.entrySet()) {
String propertyName = entry.getKey();
Object value = entry.getValue();
if (shouldAddError(propertyName, value)) {
String message = XWorkConverter.getConversionErrorMessage(propertyName, stack);
Object action = invocation.getAction();
if (action instanceof ValidationAware) {
ValidationAware va = (ValidationAware) action;
if(buttonName.equalsIgnoreCas("Next")){
va.addFieldError(propertyName, message);
}
}
if (fakie == null) {
fakie = new HashMap<Object, Object>();
}
if(buttonName.equalsIgnoreCas("Next")){
fakie.put(propertyName, getOverrideExpr(invocation, value));
}
}
}
if (fakie != null) {
// if there were some errors, put the original (fake) values in
// place right before the result
stack.getContext().put(ORIGINAL_PROPERTY_OVERRIDE, fakie);
invocation.addPreResultListener(new PreResultListener() {
public void beforeResult(ActionInvocation invocation, String resultCode) {
Map<Object, Object> fakie = (Map<Object, Object>) invocation.getInvocationContext().get(ORIGINAL_PROPERTY_OVERRIDE);
if (fakie != null) {
invocation.getStack().setExprOverrides(fakie);
}
}
});
}
return invocation.invoke();
}
protected boolean shouldAddError(String propertyName, Object value) {
if (value == null) {
return false;
}
if ("".equals(value)) {
return false;
}
if (value instanceof String[]) {
String[] array = (String[]) value;
if (array.length == 0) {
return false;
}
if (array.length > 1) {
return true;
}
String str = array[0];
if ("".equals(str)) {
return false;
}
}
return true;
}
}
You can specify you button names on which you want validation to fire. In above code I have used "Next" in code you can see
if(buttonName.equalsIgnoreCas("Next"))
Yes, you can skip calling the interceptor.
Just remove the interceptor definition from your action definition in struts.xml file.
i.e., remove <interceptor-ref name="conversionError"/>
Mainly this interceptor adds any error found in the ActionContext's conversionErrors map as a field error (provided that the action implements ValidationAware). In addition, any field that contains a validation error has its original value saved such that any subsequent requests for that value return the original value rather than the value in the action. This is important because if the value "abc" is submitted and can't be converted to an int, we want to display the original string ("abc") again rather than the int value (likely 0, which would make very little sense to the user).
After you removed this interceptor, if the struts failed to map the field with parameter of the object(i.e., from string to int), it throws result input action error.
This seems to be a better method to handle this scenario - using Conversion Validator. Repopulating Field upon conversion Error section is something very useful:
