I am try to do MessageList in blackberry using midlet, but whatever I do some expection comes up. Right now am getting NullPointerException. Here is the code
EncodedImage indicatorIcon = EncodedImage.getEncodedImageResource("img/indicator.png");
ApplicationIcon applicationIcon = new ApplicationIcon(indicatorIcon);
ApplicationIndicatorRegistry.getInstance().register(applicationIcon, false, false);
ApplicationMessageFolderRegistry reg = ApplicationMessageFolderRegistry.getInstance();
MessageListStore messageStore = MessageListStore.getInstance();
if(reg.getApplicationFolder(INBOX_FOLDER_ID) == null)
{
ApplicationDescriptor daemonDescr = ApplicationDescriptor.currentApplicationDescriptor();
String APPLICATION_NAME = "TestAPP";
ApplicationDescriptor mainDescr = new ApplicationDescriptor(daemonDescr, APPLICATION_NAME, new String[] {});
ApplicationFolderIntegrationConfig inboxIntegration = new ApplicationFolderIntegrationConfig(true, true, mainDescr);
ApplicationFolderIntegrationConfig deletedIntegration = new ApplicationFolderIntegrationConfig(false);
ApplicationMessageFolder inbox = reg.registerFolder(MyApp.INBOX_FOLDER_ID, "Inbox", messageStore.getInboxMessages(),
inboxIntegration);
ApplicationMessageFolder deleted = reg.registerFolder(MyApp.DELETED_FOLDER_ID, "Deleted Messages", messageStore.getDeletedMessages(), deletedIntegration);
messageStore.setFolders(inbox, deleted);
}
DemoMessage message = new DemoMessage();
String name = "John";
message.setSender(name);
message.setSubject("Hello from " + name);
message.setMessage("Hello Chris. This is " + name + ". How are you? Hope to see you at the conference!");
message.setReceivedTime(System.currentTimeMillis());
messageStore.addInboxMessage(message);
messageStore.getInboxFolder().fireElementAdded(message);
Can someone suggest me a simple MessageList sample for midlet to just show a String in MessageList and custom ApplicationIndicator value. If possible OnClick of message bring back the midlet from background.
use the following code:
static class OpenContextMenu extends ApplicationMenuItem {
public OpenContextMenu( int order ) {
super( order );
}
public Object run( Object context ) {
if( context instanceof NewMessage ) {
try {
NewMessage message = (NewMessage) context;
if( message.isNew() ) {
message.markRead();
ApplicationMessageFolderRegistry reg = ApplicationMessageFolderRegistry.getInstance();
ApplicationMessageFolder folder = reg.getApplicationFolder( Mes
sageList.INBOX_FOLDER_ID );
folder.fireElementUpdated( message, message );
//changeIndicator(-1);
}
Inbox inbox = message.getInbox();
Template template = inbox.getTemplate();
//Launch the mainscreen
UiApplication.getUiApplication().requestForeground();
}
catch (Exception ex) {
Dialog.alert();
}
}
return context;
}
public String toString() {
return "Name of the menu item";
}
}

It works fine, but when I receive the email it has attached an document named application/pdf.
I was trying to find out where the document's name comes from. As you can see in the below image, when I add the application type PDF, it appears exactly what I get attached in email.
The problem is that application/pdf cannot be opened with any PDF viewer app. I have to rename the document to application.pdf in order to be able to open it. Is there a way to change application/pdf with application.pdf?
If anyone is looking for the answer:
var attachment = new Attachment(stream, "report.pdf ", System.Net.Mime.MediaTypeNames.Application.Pdf);
I'm having problem with injecting my service. I've a ISettingService. I'm testing registration onmy application and using email confirmation.
So, at the EmailMessageService class which is inherit from IIdentityMessageService
I'm using Unity for Ioc. I'd registered ISettingService at unity config like below
.RegisterType<ISettingService, SettingService>()
I need to inject this interface to EmailMessageService class to access settings.
Here is the EmailMessageService class
public class EmailMessagingService : IIdentityMessageService
{
private ISettingService SettingService { get; set; }
public Task SendAsync(IdentityMessage message)
{
var fromEmailAddress = ConfigurationManager
.AppSettings["IdentityFromEmailAddress"];
var text = message.Body;
var html = message.Body;
// Do whatever you want to the message
using (var msg = new MailMessage())
{
msg.From = new MailAddress(fromEmailAddress);
msg.To.Add(new MailAddress(message.Destination));
msg.Subject = message.Subject;
msg.AlternateViews.Add(
AlternateView.CreateAlternateViewFromString(
text, null, MediaTypeNames.Text.Plain)
);
msg.AlternateViews.Add(
AlternateView.CreateAlternateViewFromString(
html, null, MediaTypeNames.Text.Html)
);
// var smtpClient = new SmtpClient("smtp.whatever.net", Convert.ToInt32(587));
// var credentials = new System.Net.NetworkCredential(Keys.EmailUser, Keys.EMailKey);
// smtpClient.Credentials = credentials;
using (var smtpClient = new SmtpClient())
{
var setting = SettingService.Query().Select().FirstOrDefault();
if (setting != null)
{
if (!string.IsNullOrEmpty(setting.SmtpHost))
{
smtpClient.Host = setting.SmtpHost;
smtpClient.Port = Convert.ToInt32(setting.SmtpPort);
if (setting.IsSmtpSsl)
{
smtpClient.EnableSsl = true;
}
}
}
smtpClient.Send(msg);
}
}
return Task.FromResult(0);

}

I am trying to implement a "Wait Screen" in my BlackBerry app. The screen is to appear when the user clicks "Login" and it should go away after login has successfully been made. I am calling the screen in the "Login" listener after which I call a methd to fetch data from webs ervice. When the data is fetched, and the new screen is shown, the "Wait Screen" should disappear. However, on clicking login I get Uncaught - RuntimeException after which new screen is displayed with the "Waiting Screen" on top of it. Can somebody help me with this?
public class MessageScreen extends PopupScreen
{
private String message;
public MessageScreen (String message)

final BitmapField logo = new BitmapField(Bitmap.getBitmapResource( "cycle.gif"));
logo.setSpace( 5, 5 );
add(logo);
RichTextField rtf = new RichTextField(message, Field.FIELD_VCENTER | Field.NON_FOCUSABLE | Field.FIELD_HCENTER);
rtf.setEditable( false );
add(rtf);
}
}
I am calling this in the "Login" click event - button listener.

Like Eugen said, you should run doLogin() on a background Thread:
final String uname = username.getText();
final String pwd = passwd.getText();
Thread backgroundWorker = new Thread(new Runnable() {
public void run() {
doLogin(uname, pwd);
}
});
backgroundWorker.start();
If you do that, you'll need to use UiApplication.invokeLater() (or another similar technique) to show your screens (back on the main/UI thread). You can't leave the doLogin() method exactly as it originally was, because it makes calls to change the UI. For example, you have a couple calls to directly use pushScreen(), which should not be called (directly) from the background.
This is not ok (from the background):
UiApplication.getUiApplication().pushScreen(nextScreen);
But, this is:
UiApplication.getUiApplication().invokeLater( new Runnable()
{
public void run ()
{
UiApplication.getUiApplication().pushScreen(nextScreen);
}
} );
But, also, what is this code supposed to do? :
UiApplication.getUiApplication().pushScreen(nextScreen);
UiApplication.getUiApplication().invokeLater( new Runnable()
{
public void run ()
{
UiApplication.getUiApplication().pushScreen( UiApplication.getUiApplication().getActiveScreen() );
}
} );
This doesn't make sense to me. What are you trying to do with those lines of code?
I see only one issue so far - networking in the UI thread. Please put all your networ operations into another Thread.run().
You could also get more detailed error description by:
1) Navigate to home screen
2) Hold alt button and press LGLG on the keyboard
3) Explore showed event log for specific error
try this -
public void fieldChanged(Field field, int context)
{
// Push appropriate screen depending on which button was clicked
String uname = username.getText();
String pwd = passwd.getText();
if (uname.length() == 0 || pwd.length()==0) {
Dialog.alert("One of the textfield is empty!");
} else {
C0NNECTION_EXTENSION=checkInternetConnection();
if(C0NNECTION_EXTENSION==null)
{
Dialog.alert("Check internet connection and try again");
}
else
{
Dialog busyDialog = new Dialog("Signing in...", null, null, 0, Bitmap.getPredefinedBitmap(Bitmap.HOURGLASS));
busyDialog.setEscapeEnabled(false);
synchronized (Application.getEventLock()) {
busyDialog.show();
}
doLogin(uname, pwd);
}
}
}
I am creating an application that will post a link onto Twitter. The following code refuses to package up for me, throwing the following error:
Error: Cannot run program "jar": CreateProcess error=2, The system cannot find the file specified
Here is the code:
public class ShowAuthBrowser extends MainScreen implements OAuthDialogListener
{
private final String CONSUMER_KEY = "<Consumer>";
private final String CONSUMER_SECRET = "<Secret>";
private LabelField _labelStutus;
private OAuthDialogWrapper pageWrapper = null;

{
_authManager = new VerticalFieldManager(NO_VERTICAL_SCROLL |
NO_VERTICAL_SCROLLBAR);
_pinManager = new HorizontalFieldManager(NO_VERTICAL_SCROLL |
NO_VERTICAL_SCROLLBAR);
authButton = new ButtonField("OK");
authPin = new TextField(Field.EDITABLE);
_authManager.add(_labelStutus );
_authManager.add(b);
_pinManager.add(authButton);
_pinManager.add(authPin);
pageWrapper = new BrowserFieldOAuthDialogWrapper(b,CONSUMER_KEY,
CONSUMER_SECRET,null,this);
pageWrapper.setOAuthListener(this);
add(_pinManager);
add(_authManager);
authButton.setChangeListener( new FieldChangeListener( ) {
public void fieldChanged( Field field, int context ) {
if( field == authButton ) {
doAuth(authPin.getText());
}
}
} );
}
public void doAuth( String pin )
{
try
{
if ( pin == null )
{
pageWrapper.login();
}
else
{
this.deleteAll();
add(b);
pageWrapper.login( pin );
}
}
catch ( Exception e )
{
final String message = "Error logging into Twitter: " +
e.getMessage();
Dialog.alert( message );
}
}
public void onAccessDenied(String response ) {
updateScreenLog( "Access denied! -> " + response );
}
public void onAuthorize(final Token token) {
final Token myToken = token;
_tokenValue = StoreToken.fetch();
_tokenValue.token = myToken.getToken();
_tokenValue.secret = myToken.getSecret();
_tokenValue.userId = myToken.getUserId();
_tokenValue.username = myToken.getUsername();
_tokenValue.save();
UiApplication.getUiApplication().invokeLater( new Runnable() {
public void run() {
deleteAll();
Credential c = new Credential(CONSUMER_KEY,
CONSUMER_SECRET,
myToken);
PostTweet tw = new PostTweet();
String message="Testing BB App";
boolean done=false;
done=tw.doTweet(message, c);
if(done == true)
{
Dialog.alert( "Tweet succusfully..." );
close();
}
}
});
}
public void onFail(String arg0, String arg1) {
updateScreenLog("Error authenticating user! -> " + arg0 + ", " + arg1);
}
private void updateScreenLog( final String message )
{
UiApplication.getUiApplication().invokeLater( new Runnable() {
public void run() {
_labelStutus.setText( message );
}
});
}
}
The odd thing is, if I remove the following lines, it packages just fine:
authButton.setChangeListener( new FieldChangeListener( ) {
public void fieldChanged( Field field, int context ) {
if( field == authButton ) {
doAuth(authPin.getText());
}
}
} );
Any help would be appreciated as I really need the field listener attached to this screen.
With code like authButton.setChangeListener(null), it does package successfully however I do need code with FieldChangeListener to do something.

I have 2 ComboBoxes on my form. I create the bindings as follows:
TestClass myclass = new TestClass("Instruments");
myclass.Add(instr1 = new TestClass("INSTR1"));
myclass.Add(instr2 = new TestClass("INSTR2"));
myclass.Add(instr3 = new TestClass("INSTR3"));
myclass.Add(instr4 = new TestClass("INSTR4"));
instr1.Add(app1 = new TestClass("app1"));
instr1.Add(app2 = new TestClass("app2"));
instr1.Add(app3 = new TestClass("app3"));
instr1.Add(app4 = new TestClass("app4"));
instr2.Add(app5 = new TestClass("app5"));
instr2.Add(app6 = new TestClass("app6"));
instr2.Add(app7 = new TestClass("app7"));
instr2.Add(app8 = new TestClass("app8"));
mysource = new BindingSource(myclass, null);
selectedComboBox1.DataSource = mysource;
selectedComboBox1.DisplayMember = "NAME";
mysource2 = new BindingSource(selectedComboBox1, "SelectedItem");
selectedComboBox2.DataSource = mysource2;
selectedComboBox2.DisplayMember = "NAME";
The class used for the binding looks as follows
class TestClass : BindingList<TestClass>, INotifyPropertyChanged
{
public event RunTestChanged RunTestChangedEventHandler;
public TestClass()
{
this.test = "";
this.name = "";
this.runTest = true;
}
public TestClass(string name)
{
this.test = "";
this.name = name;
this.runTest = true;
}
public TestClass LIST
{
get
{
return this;
}
}
public string NAME
{
get
{
return this.name;
}
set
{
this.name = value;
if (this.PropertyChanged != null)
{
this.PropertyChanged(this, new System.ComponentModel.PropertyChangedEventArgs("NAME"));
}
}
}
public string TEST
{

{
return this.test;
}
set
{

}
}
private bool runTest;
private string name;
private string test;
public event System.ComponentModel.PropertyChangedEventHandler PropertyChanged;
}
when the form first loads the 2 comboboxes are filled as they should be with the expected items. However, if i change an item in selectedComboBox1, the items in selectedComboBox2 aren't updated. I know that I can subscribe to the selectedComboBox1 SelectedIndexChanged event and then rebind the DataSource on selectedComboBox2 and everything will work as expected.
For example:
void selectedComboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
mysource2.DataSource = selectedComboBox1.SelectedItem;
mysource2.DataMember = null;
}
Another alternative that works is to perform the databinding as follows:
mysource = new BindingSource(myclass, null);
mysource2 = new BindingSource(mysource, "LIST");
mysource3 = new BindingSource(mysource2, "LIST");
selectedComboBox1.DataSource = mysource;
selectedComboBox1.DisplayMember = "NAME";
selectedComboBox2.DataSource = mysource2;
selectedComboBox2.DisplayMember = "NAME";
However I wanted to know if there was a way to avoid having to subscribe to the event or performing the databinding in a different manner and just have the 2nd ComboBox be updated via the BindingSource using the SelectedItem property. In the end I'm curious to know how to get the BindingSource to be updated via the SelectedItem databinding and if it's not possible what is preventing it from working.
Thank you for your help.
i have the same issue and got resolved by binding Name to SelectedValue of combobox and set ValueMember to be "NAME" property
selectedComboBox1.DisplayMember = "NAME";
selectedComboBox1.ValueMember = "NAME";
