I am trying to create a dialog box that will allow me to either change address of my location or just confirm the address that appears within the dialog box by clicking ok.

Welcome to the forums!

What part of this task gives you trouble? Have you looked at PopupScreen and TextField (or, say, EditField) documentation?

[onelson06]

Arkadyz, my reason for asking the question above is because I have an app that is pushing location-based data to a map. I would like for the users to be able to change the address of the location if needed via a dialog box before proceeding(please advise if a popup screen would be better). I have tried creating a CustomDialog that extends the Dialog but I am not sure how to call it from the class where the button is located and analyzed.

Then take a look at the Dialog class documentation - especially add and doModal methods. You add a variation of a TextField, of course. Create a public method in your CustomDialog which extracts the text from that TextField and returns it to the caller and call it after the dialog is dismissed (doModal returns).

arkadyz, do you know where I can find an example of what you mention to do

[arkadyz]

This is a very basic task so I don't think you will have many code examples in the knowledge book or anywhere in this forum. Try BlackBerry Manuals and Guides for Developers - especially UI Guidelines for BlackBerry Smartphones and BlackBerry Java development guides for starters.

Is this similar to what you were saying:

public final class TestDialog extends Dialog
xxx123;
private EditField userNameField;
private EditField passwordField;

public TestDialogxxx40;String choicesxxx91;xxx93;, int valuesxxx91;xxx93;xxx41;
xxx123;
superxxx40;"Login Information", choices, values, Dialog.OK, Bitmap.getPredefinedBitmapxxx40;Bitmap.INFORMATIONxxx41;, Dialog.GLOBAL_STATUSxxx41;;

userNameField = new EditFieldxxx40;"User Namexxx58; ", "", 50, EditField.EDITABLExxx41;;
passwordField = new EditFieldxxx40;"Passwordxxx58; ", "", 50, EditField.EDITABLExxx41;;

Manager delegate = getDelegatexxx40;xxx41;;
ifxxx40; delegate instanceof DialogFieldManager xxx41;
xxx123;
DialogFieldManager dfm = xxx40;DialogFieldManagerxxx41;delegate;
Manager manager = dfm.getCustomManagerxxx40;xxx41;;
ifxxx40; manager != null xxx41;
xxx123;
manager.insertxxx40;userNameField, 0xxx41;;
manager.insertxxx40;passwordField, 1xxx41;;
xxx125;
xxx125;

xxx125;
xxx125;

Your post is very strangely formatted, but I can guess the approach. I'd say you are doing it the hard way, but the overall idea is correct. I suggest you add two public methods which extract username and password:

public String getUserName() {
  if (userName != null) {
    return userName.getText();
  }
  return null;
}

public String getPassword() {
  if (password != null) {
    return password.getText();
  }
  return null;
}

 Call these methods once the dialog closes. Check whether the user pressed 'OK' or 'Cancel' before doing so.

Arkadyz, I created the methods you stated and I am trying to display the screen with the following:

screen = new CustomPopup();
UiApplication.getApplication().pushModalScreen(screen);
String newEndPoint = screen.getEndPoint();

but I get an error saying cannot find symbol method pushModalScreen. Do you have any clue as to why this is happening.
