How to make view Java Bean as .ocx file.
Hi All,
I want to use a visual Java Bean in Visual basic. So that I can modify all the bean properties as modify properties in a ocx file.
I used ActiveX Com bridge downloaded from Sun's site. But the packager
makes a .tlb file .
This file can only be added as a reference in visual basic but not as a ActiveX control. Is there any way out to do that???
Thanks & regards.
Nimesh
The packager creates a registry file and a tlb file.
After registering this .reg file, java bean can be used as an ActiveX control.
From within Visal Basic, select the "Tools" menu and "Custom Controls" item and add the Bean control that was generated.
Avinash.

How to make my java bean internationalization?
hi,
I have a project on tomcat. I have rewrite my jsp to multi-language according to user's browse language setting. User's language is English, the jsp shows them English. User's language is Chinese, the jsp shows them Chinese, and so on. But in my java bean code, some exception are thrown out with some message or alert. Can anybody tell me how to make these java beans show the language string acording to user's browse language setting?
thx
PierreDear one_dane,
Thank you. That is a great document to me. The fact is that my owner code throws exception with a string. The code is:
if(amount<0) throw new Exception("Please input correct amount.");
If the code is in jsp, I can convert it to a internationalized String using struts tag <bean:message...>. But it is in a deep function of java class. So must I add a Locale object parameter to the function and all calling functions?
thx
yours,

How to make a Java program that recognises a function of two variables...
How to make a Java program that recognises a function of two variables to assign values to that?
First I will give an example and then do the question.
Ex1.
We have any function, eg.y = x ^ 2 + 1 (read 'y' equals 'x' high to the square), a function of the second degree.
To build the graph of this function attach values to 'x' to find the values of 'y'
And thus mount the pair ordered (x, y) which represents a point on the Cartesian plane.
Assigning values to 'x' 'we can build up a table that gives us the pairs ordered:
We can use any numbers, but arfer interval [-3.3]
X | y = x ^ 2 + 1
-3 | Y = (-3) ^ 2 +1 = 10
-2 | Y = (-2) ^ 2 +1 = 5
-1 | Y = (-1) ^ 2 +1 = 2
0 | y = (0) ^ 2 +1 = 1
1 | y = (1) ^ 2 +1 = 2
2 | y = (2) ^ 2 +1 = 5
3 | y = (3) ^ 2 +1 = 10
We then ordered the pairs:
(-3.10), (-2.5); (-1.2), (0,1), (1,2), (2,5), (3,10)
Tabem that can be represented by a table:
X | y
-3 | Y = 10
-2 | Y = 5
-1 | Y = 2
0 | y = 1
1 | y = 2
2 | y = 5
3 | y = 10
Now I begin to explain my doubts.
See this program:
Ex2
* To change this template, choose Tools | Templates
* And open the template in the editor.
Encontrando_o_valor_de_y package;
* @ Author des Soldat Gottes
Import javax.swing.JOptionPane;
Public class (Main
* @ Param args the command line arguments
Public static void main (String [] args) (
Int x, y;
String x1;
X1 = JOptionPane.showInputDialog ( "We have the function y = x + 1 \ n" +
"Assign a value for 'x',"); / / receives a value for the function y = x + 1
X = Integer.parseInt (x1); / / tranforma String in int
Y = x + 1; / / receives the value of 'x' and calculates' y '
JOptionPane.showMessageDialog (null, "The value of 'y' is: \ t \ t" + y);
/ / Displays the value of 'y'
System.exit (0);
We see that the program receives above a value for 'x' and replaces the function contained in the program, y = x + 1, and so is the value of the variable 'y'.
In: x1 = JOptionPane.showInputDialog ( "We have the function y = x + 1 \ n" +
"Assign a value for 'x',");
The entry is a number and that number is assigned aa ja existing function in the (y = x + 1).
The question is: would it be possible to come to a function?
Ex: the program ask: DIGITE THE FUNCTION?
The USUARIO DIGITARIA A FUNCTION ANY, TYPE: y = x ^ 2 +1
The program would recognize the function and give numerical values to that function as Ex1, at the beginning of this text.
And then to find the values of the x and y launch a table.
It would be possible that?
By invez of entering with a number so that the program sustitua a function ja existing as Ex2, seen above, entering with a function quaquer (type: y = x ^ 2 +1) for the program atribuisse values to that function and then create a table of values as Ex1.
I hope it has been easier to understand my doubts now.
Thank you for your attention!

But as it applied to a program?
How to create a program that recognizes that the entry coefficients?Are you asking about how to parse out the coefficients from the string "3x^4 + 4x^3 - 8x^2 + 5x^1 + 2x^0"? If you define the format to strictly follow that example, this should get you started:
Strip out the spaces
Split the String on "x^"
That should give you [3, 4+4, 3-8, 2+5, 1+2, 0]
Split each resulting String on "+ | -", preserving the operator as a token so you can apply the correct sign to the coeff.
That should leave you with [3, 4, +, 4, 3, -, 8, 2, +, 5, 1, +, 2, 0]. Every other number is a coeff, the rest are the degrees.
You can strip out the +, since those coeffs are already positive, and strip out the - after negating the following number. This is all assuming that you have to write this yourself. There is no doubt already a library or 5 out there that does this for you. -
How to attach a java bean in forms6i
Hi,
I am new to oracle forms6i. i just want to ask on how to attach a java bean to forms6i.i did putting the full directory path to the implementation class but it has an error, bean not found. what should i do?
Your help is highly appreciated.The implementation class should contain the package and class name of the bean e.g. com.groundside.beans.DateFieldBean, not a directory location. The bean itself is loaded from the JAR files specified to be downloaded with the applet.
If you are running client server then you can't use JavaBeans this way - it's a web only feature. -
How to make a java program, that can be used by c++ application
I'm developing a Java web application (WEBapp), but I have also a c++ program.
C++ program must use WEBapp method to communicate on the web.
How to make a Java public function that accept value, elaborate, then return the resul to c++ application?jschell wrote:
You have C code.
You have Java code.
The two must communicate.I have a c++ program, and a Java program.
C++ program wants to communicate on the web (send text), and I'm trying to add this functionality to it creating a Java program.
NOW THE PROBLEM? How c++ program can use java-program (in local) to send data on the web?
You can just JNI to communicate either from java to C++ or from C++ to java. That is direct communication in that there is a single process involved. Thus you will no longer have a java application and a C++ application but rather a single application.I don't know JNI, i found http://java.sun.com/docs/books/jni/ and I think is too difficult to implement?
You can use files or sockets to communicate. Using sockets allows for any number of additional protocols including the previously mentioned web services. Those methodologies would allow more than one application to exist.I developed yesterday a java-side-interface using socket (in local host 127.0.0.1). So the c++ program must write or read to/from the socket to comunicate to java (then the java program send data on the web).
Finally it might be the case that you have a C++ application which you cannot modify. In that case then you MUST use whatever input/output mechanism that it supports. There is no choice. And until you have fully determined what those mechanisms are it is pointless to discuss a solution.I can modify the application, but I don't have developed it. The c++ application use a third-part dll (taken from SKYPE) to comunicate on the web: I have to remove the dipendence from this dll, and add the java program: java program must substitute the dll. It must be non-invasive to the c++ program. DLL calls can be "send(data)" or "receive(data)" or similar.
For this do you think that JNI is a must, or I can use soket on local host? -

Dear Michael, good day!
1. As per your instruction, I turned off iTM.
Small discrepancy – where are two screens with iTM switch:
-Settings > iTunes & App Store.
-Settings > Music
I switched OFF in both.
NB: I turned device to English for convenience.
2. My next step was Setting > General > Usage – tapped {Music};
{All music} screen appeared; I swiped it and taped Delete.
3. I performed “hard reset” …………………………………..
4. Switched back On iTM
5. Taped Music app on Home screen
iTM has started – (it took 18 minutes to completed, 60 mbps Wi-Fi speed )
Regret to inform… All the same:

How to make view automatically scroll when keyboard show up
Hi all
I'm like a totally noob for objective-c coding, let alone the iPhone programing. :P
Anyway, I somehow manage to create a simple application that receive input via UITextField, do some simple math, then display the result in other UITextFields (which can act as a input vice versa).
Problem is, when I use the UITextField at the buttom of the screen as an input, the keyboard will block that text field out of my view, so I could not see what I'm typing at all.
That's the question. How to make my view scrollable, and make it simply scroll itself out of the way when the keyboard is shown? I already inherit my view from UIScrollView, but don't know what to do next. Can you guys help enlighten me, please?
ThanxOf course, if you're dealing with textFields, you should change a few things try something like that in your .m file :
- (void)textFieldDidBeginEditing:(UITextField *)theTextField
if ([theTextField isEqual:yourTextField])
// Restore the position of the main view if it was animated to make room for the keyboard.
if (self.view.frame.origin.y >= 0)
[self setViewMovedUp:YES];
// Animate the entire view up or down, to prevent the keyboard from covering the author field.
- (void)setViewMovedUp:(BOOL)movedUp
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.3];
// Make changes to the view's frame inside the animation block. They will be animated instead
// of taking place immediately.
CGRect rect = self.view.frame;
if (movedUp)
// If moving up, not only decrease the origin but increase the height so the view
// covers the entire screen behind the keyboard.
rect.origin.y -= kOFFSETFORKEYBOARD;
rect.size.height += kOFFSETFORKEYBOARD;
else
// If moving down, not only increase the origin but decrease the height.
rect.origin.y += kOFFSETFORKEYBOARD;
rect.size.height -= kOFFSETFORKEYBOARD;
self.view.frame = rect;
[UIView commitAnimations];
- (void)keyboardWillShow:(NSNotification *)notif
// The keyboard will be shown. If the user is editing the author, adjust the display so that the
// author field will not be covered by the keyboard.
if ([yourTextField isFirstResponder] && self.view.frame.origin.y >= 0)
[self setViewMovedUp:YES];
else if (![yourTextField isFirstResponder] && self.view.frame.origin.y < 0)
[self setViewMovedUp:NO];
#pragma mark - UIViewController delegate methods
- (void)viewWillAppear:(BOOL)animated
// watch the keyboard so we can adjust the user interface if necessary.
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:)
name:UIKeyboardWillShowNotification object:self.view.window];
- (void)viewWillDisappear:(BOOL)animated
[self setEditing:NO animated:YES];
// unregister for keyboard notifications while not visible.
[[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardWillShowNotification object:nil];
be sure to invoke the method when you dismiss the keyboard, so that the view "falls back" to its normal state:
if (self.view.frame.origin.y < 0)
[self setViewMovedUp:NO];
Of course, declare the method
(void)setViewMovedUp:(BOOL)movedUp;
in the .h file
and the #define you will use in you .m file :
// the amount of vertical shift upwards keep the text field in view as the keyboard appears
#define kOFFSETFORKEYBOARD 50.0
// the duration of the animation for the view shift
#define kVerticalOffsetAnimationDuration 0.30
good luck ! -
