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.

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.

How to access assemly code in java

dear i want to access assembly code in java . plz help me. thanx.

Assembly, C, C++, Fortran, etc. can be accessed most directly via the Java JNI facility. For assembly, you'll have to write a native C/C++ layer to accept the JNI call and forward it to the assembly code. If the assembly code is C-callable (i.e. it conforms to the C calling conventions on your platform) then the job is really no more difficult that calling any C routine.

How to call c++ code from java

i have a third party dll written in c++. I want to call its methods in java. I searched web and found that I have to use JNI for this. I have seen examples on web writing c++ code and then using it from java through JNI, but can anybody please point to me the example where i have a predefined library or dll in c++ and i have to call it in java. I think that I may have to declare methods in library as native in java and then write a wrapper implementation (dll) in c++ which actually calls the library or dll functions. But, then how will I call methods of dll from my wrapper code.
Any examples, please point
Regards,
Farooq

There's a JNI forum here that may be a better place for this question; though given the general nature of the question, I suspect that they'll refer you to a tutorial. good luck.

How to call VB code to JAVA

hello,
can we create DLL files in VB. please write step by step code. please help me.

Are you asking about how to create a DLL using Visual Basic?
That question does not have anything to do with Java.
Please find a forum about Visual Basic somewhere and ask your question there.

How to programming bar code by java?

hi,
Does anybody know how to write programming to translate the charactor( such as num or char) into bar coding and how to translate the barcode back into charactor by java?

Hello,
Is it possible you could post all of teh object code for printing bar codes? Thanks.
Ok ... it's been about 4 years since I'd written this,
so there may be better ways of doing it now
(especially since jsk1.4 now allows you to draw
directly to screen!)
1) I created an object extending Canvas
2) In my paint method, I needed to draw the code & the
numbers below the code:
public void paint(Graphics g)
// calculate text length & draw the barcode
num = text.length();
length = ((3*wide)+(6*narrow))*(num+2) +
+ (num+1)*seperate;
DrawBarcode(g);
3) In the DrawBarcode method
I drew rectangles where I needed the barcodes (ie:
g.fillRect) - making sure that there was spacing
required ... which depends on the barcode you're
using.
Do you have any specific questions?

How to write JSP code in Java Script Code

Hello friends
I have code like
<script language="JavaScript">
function f()
(some code is here)
</script>
Now i wants to put some JSP code in f()
So can i do this ? IF yes then how ?
(one solution may be make JSP function and call that JSP function from the f().So in that case how can i call JSP function from JavaScript??
If other method is there then please mail me

If it's a simple matter of mixing client-side code with server side code, it can be done so long as you're using the server-side to write the client-side.
For example:
<h1>Good Morning Mr. Phelps</h1>
<input name=anybodyFunction type=text>
<% if (userIsAdmin) { %>
<input name=adminOnlyFunction type=text>
etc.
<% } %>
<h1>This browser will self-destruct in ...</h1>
That's JSP (inside the <% %>) mixed with HTML.
Javascript goes 100% on the client-side. If you're writing JSP with inter-mixed HTML, you might have to inter-mix the java-script.
For example: Suppose you need to validate the form. "adminOnlyFunction", among others, is a mandatory field, and you want the Javascript to only submit the form if all mandatory fields are set. Well, if the user is NOT an administrator, then that field WILL be left blank.
One way to handle that is with mixing JSP/HTML/Javascript on the SERVER side.
<h1>Good Morning Mr. Phelps</h1>
<input name=mandatory1 type=text>
<input name=optional1 type=text>
<% if (userIsAdmin) { %>
<input name=adminOnlyFunction type=text>
<% } %>
<input name=submit type=button value=Submit onClick="checkit()">
etc. etc.
<script language=Javascript>
function checkit() {
var f = document.form;
if (
� � f.mandatory1.value == ""
� � || f.mandatory1.value == ""
� � || f.mandatory2.value == ""
<% if (userIsAdmin) { %>
� � || f.adminOnlyFunction.value == ""
<% } %>
� � � � ) {alert ("Hey! You left out a required field!!");}
etc. etc. etc.
I imagine THIS might be what is meant by "mixing JSP with Javascript", and in this particular fashion, it can be done. What you're doing is making decisions on the server side over what to write out to the client. That client code can make further decisions based on user input.
However, once it's on the client side, you can not have anymore JSP code. The client NEVER runs JSP code.

How to get exit code from C code when calling java method via JNI?

Hi, All
in my project, i need to call a java method from C code using JNI, yet I do
not know how to
retrieve the exit code of java program. the java code is like below
public static void main(....)
if(error){
System.exit(-77);// the exit code is -77
and the JNI c code may like below
/* Invoke main method. */
(*env)->CallStaticVoidMethod(env, mainClass, mainID, mainArgs);
//here I want to retrieve the exit code from java to check if there is an
error
any suggestions? thanks

Hi Liang Zhang,
In your C code add:
void (JNICALL y_exit)(jint code) {
and when you are initialazing JVM options add:
JavaVMOption options[...];
options[...].optionString = "exit";
options[...].extraInfo = y_exit;
See http://java.sun.com/j2se/1.3/docs/guide/jni/jni-12.html

Tips on how to write efficient java code for java mapping

hi
I do not have much knowledge in Java
Can anybody tell me some tips on how to write efficient and optimised java code to be used in java mapping
Thanks,

hi D'za,
JAVA in xi
A very important place where you will use JAVA in XI is while doing your Mapping. There will be cases when JAVA MAPPING is the best solution to go for. There are 2 types of Parsers available for JAVA Mapping. DOM Parser and SAX parser. Just got through the following links to understand more on Java Mapping and the APIs available.http://java.sun.com/j2se/1.4.2/docs/api/javax/xml/parsers/package-summary.html http://java.sun.com/j2se/1.4.2/docs/api/org/w3c/dom/Document.html http://java.sun.com/j2se/1.4.2/docs/api/org/w3c/dom/package-frame.html /people/prasad.ulagappan2/blog/2005/06/29/java-mapping-part-i

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.

What about the converter I told you about?
