How to convert Vb code into java?

Hi,
I want to know how to make conversion a visual basic source code into java. The conversion could be (1:1) scale.
Is there any compilers making the live easier (solving this problem) ?
Thank you all.
Abu_ramla

Use the JNI. VB doesent actually do anything on its own. Its just a series of calls on COM objects to performs all its work. You can call these same COM objects using the Java Native Interface or JNI. You wont have access to things designed in VB though like forms, you will have to redesign those.
This will take extensive knowledge of COM, VB, Java, and JNI. It will take you about 1 year to get up to speed. I would say to not do this.

"embed" image data into java code

I have a mind that is it possible embed image file into java code?
That mean an image file information already store in java code, thus no need using the image file in run-time. Then can prevent user change other image file instead.
Do anyone try before, are there technologies required?
I just want to know is it possible or not....thanks.

technologies? The solution you are asking for is all about storing your data in static variables such as byte[][] used to build your image instance. I guess you should have a look at the different constructors of BufferedImage.

Pythagors into java-code (i got the idea, i think, but need it simplified)

Goodday all :),
I have been trying to turn the forumula | a^2 + b^2 = c^2 | into java code.
To clear it up a little more;
1. Define unknown variable
2. Define values of other two variables
3. Program calculates
x1. unkown variable is 'a'
x2. b = 20 , c = 40
x3. a = [(40^2) - (20^2)] ^0.5 (sorry couldnt figure out superscript)
What i was thinking as a concept;
1. Java asks for uknown value -> user defines as 'a' , 'b' or 'c'.
2. Java If else statement
2.1 if 'd' -> java asks again
2.2 else 'e' --> java asks again etc (if else statemenst from d - z)
import java.io.*;
public class example {
     public static void main(String[] args) {
          System.out.println("define uknown value");
          BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
          boolean running = true;
          while(running) {
                    String line = reader.readLine();
                    if (line.startsWith("d")) {
                         System.out.println("wrong input, define unknown value");
                         running = true;
                         } else      if (line.startsWith("e")) {
                         System.out.println("wrong input, define unknown value");
                         running = true;
                         } else      if (line.startsWith("f")) {
                         System.out.println("wrong input, define unknown value");
                         running = true;
                         } else      if (line.startsWith("g")) {
                         System.out.println("wrong input, define unknown value");
                         running = true;and furter i was thinking;
If a, b or c is pressed it will ask for the values of the other two
and it will be such a code as above, repeating itself;
                    String line = reader.readLine();
                    if (line.startsWith("a")) {
                         System.out.println("please define b");
                         running = true;
                         if (line.startsWith("1")) {
                         int x = 1;
                         System.out.println("b=1");
                         running = true;
                         } else      if (line.startsWith("2")) {
                         int x = 2;
                         System.out.println("b=2");
                         running = true;
                         } else      if (line.startsWith("3")) {
                         int x = 3;
                         System.out.println("b=3");
                         running = true;and so on till, lets say 1000?
Now my question is;
Is this the right way to make this program?
I would have like a .java file of severel megebytes if i wanted the values to get up to 10000 or something >.<

Aargh! No. This code snippet might be of help.
try {
   int x = Integer.parseInt("42");
   System.out.println("X = " + x);
} catch( NumberFormatException e ) {
   System.err.println("Not a number: " + e);
   e.printStackTrace();
}You would probably also find it useful to read about "regular expressions" if you always expect the formula to have exactly the same form.

Converting this VBScript into Java???

HI
I hava found this VBSCript. But I like to work on java.Is it possible to convert this into java code. Basically the script runs something in the remote machine. If its possible ,would u pls tell me what special package I need ??
call execprog ("217.138.120.34","c:\acad_deploy\AdminImage\install.bat")
sub ExecProg(ServerName, ProgramName)
'     dim process as object, processid as long, result as long
     set process=getobject("WinMgmts:{impersonationLevel=Impersonate, authenticationLevel=pktPrivacy}\\" & servername & "\root\cimv2:Win32_Process")
     result=process.create(programname, null, null, processid)
     if result=0 then
         msgbox "Command executed successfully on remote machine"
     else
         msgbox "Some error, could not execute command"
     end if
end sub Thanks in advance

I hava found this VBSCript. But I like to work on
java.Is it possible to convert this into java code.Yes, it is possible to convert the VBScript program in to Java code. You need to identify what the program (script) does and what the other programs are doing as well. (You said the VBscript calls other programs on remote machines). After this, design a way to implement same functionality with Java.
Basically the script runs something in the remote
machine.What "something"?
If its possible ,would u pls tell me what
special package I need ??It is possible, in order to convert the VBScript program to Java, you will have to create a Java package to contain the class hiearchy, i.e. com.admin.install.*
And of course you will need packages from J2SE and possibly J2EE. The Runtime and Process classes from J2SE are examples what is available. These objects can be used to used to call the other programs. Your design will depend on details of the other programs.
Do you plan on converting the "install.ba" program to Java as well?

Being picky, that's not C++, that's C. Standard headers in C++ dont' have .h after them, loop variables are scoped with the for, you use constants rather than #defines, etc..
C and C++ both don't initialise arrays by default; you'd have to write an initialiser to get it to zero out the array:
int s[sz][sz] = {};gcc will insert a call to memset to zero the array.
If the author was assuming that the array was zeroed out, there would be no point zeroing the first row and column.
The code reads values which haven't been initialised. If you mark such values explicitly undefined, and change the program to report an error when undefined, then you get several cases where the program makes such report.
So either it' s a primitive random number generator (some random number generators use uninitialised memory as a source of randomness), or it's buggy, or it's processing undefined data and throwing away the result. Either way, it cannot be directly be ported to Java if the undefined values (which are limited to a small area of the ouput) are significant.

Converting oracle forms into java forms

Hi all,,
would help me plz on how to convert oracle forms into java using any tool;
Is Jheadstart is the tool,, im having jeveloper version 10.1.2.1.0

There are at least two companies that are marketing Forms to Java conversion tools. I'm sure that a good Google search will locate them, and they are frequent exhibitors at Oracle-oriented conferences like Collaborate and ODTUG Kaleidoscope. But there are problems associated with doing this. I urge anyone who is considering such a project to read this article by Grant Ronald: http://www.oracle.com/technology/products/forms/pdf/10gR2/formsmigration.pdf
You should carefully ask yourself and your clients and management, "Why do you want to do this?", "What benefits are you trying to realize?", "Does this make sense, and are there other options that we should be exploring?"
For instance, many people are trying to protect themselves because "Forms is going away". Oracle has stated again and again that Forms is NOT going away. In fact the recent Fusion Middleware 11g release included a new version of Forms with some significant enhancements. You may do very well just by upgrading to the latest version of Forms.
If you do decide that it still makes sense to convert, I suggest that rather that converting, you may want to redevelop from scratch. Keep the database if it is well designed - a well designed, stable database will outlast any front end that you may use against it. Then take full advantage of the capabilities of your new toolset, and leave behind the limitations and inapplicable methodologies of your old one. Oh, by the way, don't use JDeveloper 10.1.2. Use 11g if you can, or 10.1.3.5 if you must.

How to convert csv files into java bean objects?

Hi,
I have a CSV file, I want to store the data availabale in that csv file into java bean, I am new to this csv files how can I convert CSV files into java beans.
Please help me.
Adavanced Thanks,
Mahendra

You can use the java.io API to read (and write) files. Use BufferedReader to read the CSV file line by line. Use String#split() to split each line into an array of parts which were separated by comma (or semicolon). If necessary run some escaping of quotes. Finally collect all parts in a two-dimensional List of Strings or a List of Javabeans.

Convert Oracle Forms into Java (swing & JSP's)

Dear All,
We are currently in the process of evaluating our upgrade of system, which is using forms 4.5. One of the options we are considering at this stage is converting all forms into Java program. I am currently doing some pilot work on this project. I am using FormsWizard, a product of InformatikAtelier Gmbh, along with Forms 6i and Jdeveloper 9i. Has any one done this before in this group? Your assistance is much appreciated.
Regards
Michael Sesuraj.

Grant, Thanks for that mail. It was very useful article. The article has lots of brilliant points consider. I may have to discuss with our System Architect. With my experience in both forms and Java, it is hard to justify the business benefit out of this conversion. We are a strong Oracle house and have no intention of moving towards J2EE at this stage.. Thanks once again.

How to convert pl/sql code into java/j2ee

Hi,
We have a PL/SQL Oracle App server application that we will support if we can convert in j2ee/java. But when i did take a look at the code, these pl/sql contains all HTML and java code inside the stored procedures.
And iam looking to explore some tools and mechanisms that can convert these pl/sql in a JAVA application so that i can deploy this new app into my BEA81 environment.
Does any body has any idea:
a) How to convert from pl/sql > java ?
b) Any plugins or tools of BEA that can run these pl/sql (the way thay are currently...i.e w/o converting) in BEA 81 container ?
thanks, sangita

these pl/sql contains all HTML and java code insideJava or JavaScript. They are not the same. I wouldn't expect to see Java inside html, whereas JavaScript would be intermixed. On the other hand you might have a java stored proc (Oracle 9/10) which is generating HTML.
>
Does any body has any idea:Refactor.
I doubt it just has html and JavaScript/Java. So what you have is a mess that mixes several things that should have been seperate in the first place.

Converting String into Java code

Hi everyone,
I will describe the scenario I have. I have a GUI application. I want the user to write some Java code in a text box and plug that code during runtime. Is there a way in Java so that a string could be used as a Java code?
You help is really appreciated.
Thanks
RG

catch the string input
output string (code) to file
call javac on the file you made
that's it, you have a class, and you can run it/load it

3DES - Php crypto codes 2 Java codes convertion problem

I give all php and java codes I convert one by one but I didnt get same result where is my mistake and what shall I do. Thanks for all.
Php Code
$key = "db9ca45ee012dcabaff193ca";
$input = sha1("MehmetKaraman");
$td = mcrypt_module_open('tripledes', '', 'ecb', '');
$iv = mcrypt_create_iv (mcrypt_enc_get_iv_size($td), MCRYPT_RAND);
mcrypt_generic_init($td, $key, $iv);
$encrypted_data = mcrypt_generic($td, $input);
mcrypt_generic_deinit($td);
mcrypt_module_close($td);
echo sha1(bin2hex($encrypted_data));
Output : d7eaa53ab43683a1323cfae877a24efb4a918411
Java Code :
String message= MehmetKaraman;
byte[] input = MessageDigest.getInstance("SHA1").digest(message.getBytes("utf-8"));
     final Cipher cipher = Cipher.getInstance("DESede/ECB/NoPadding");
     final SecretKey key = new SecretKeySpec("db9ca45ee012dcabaff193ca".getBytes("utf-8"), "DESede");
cipher.init(Cipher.ENCRYPT_MODE, key );
if( input.length % 8 != 0){
     byte [] in2 = new byte[input.length+ 8- input.length%8];
     for(int i = 0;i<input.length;i++){
     in2=input[i];
     input = in2;
     final byte[] encrypted_data = cipher.doFinal(input);
     System.out.println(bin2hex(MessageDigest.getInstance("SHA1").digest(bin2hex(encrypted_data).getBytes())));
Output : 626b61642ec4ba8f7467933832619d492a6fdde1

Either you need$input = sha1("MehmetKaraman", true);or in your Java you need to hex encode your sha1 digest before encrypting. When I do either of these and emulate your Java bin2hex() method I get a match.
I don't understand why people seem unable to do simple debugging. If you had read the PHP documentation for the sha1() function and had printed out the results at each stage it would have been obvious.
P.S. The zero padding implemented by your codeif( input.length % 8 != 0){
byte [] in2 = new byte[input.length+ 8- input.length%8];
for(int i = 0;i<input.length;i++){
in2=input[i];
input = in2;
}can be replaced by 1 line using one of the methods in class java.util.Arrays.
