Design GUI in VB, put it into Java code !!!!

Hi Guys!
I have just developed software named Xtreme VB2J that builds java classes from the Visual Basic form files (.frm). Java does not have any built-in Integrated Development Environment (IDE) for Graphical User Interface (GUI) design; on the other hand, Visual Basic (VB) has a very nice and easy IDE for GUI design. This software is just an preliminary approach to integrate the power of EASY-GUI-Design of VB and Java to reduce wastage of a-lot-of time in software development.
Before Running VB2J
Since this software originally has been designed in Visual Basic, before running, your computer must have Visual Basic Runtime files or Visual Basic itself installed. You may obtain it from MyDownload section of my website or directly from: http://download.microsoft.com/download/vb60pro/install/6/Win98Me/EN-US/VBRun60.exe
Hope you won�t be sick of Layout Managers anymore!! :)
Try it today from the MyDownload section at: www.tanzimsaqib.tk
Happy GUI design!! :D
Thank you!

Obviously Zim you are not up to date on what is available for Java GUI building and what IDEs are out there. There are a host of products already available for free that far surpass anything I've used in VB (and I've developed with all flavors of VB for over 10 years now).
Come away from the dark side and into the light.
BTW: you don't have to use layout managers in Java either, but then just why wouldn't you want your application to resize smoothly?

"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 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

Putting a helloword.java code to run on Sun Java Web Server

Hello,
Given helloworld.jsp:
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class HelloWorld extends HttpServlet {
public void doGet(HttpServletRequest req, HttpServletResponse res)
               throws ServletException, IOException {
     res.setContentType("text/html");
     PrintWriter out = res.getWriter();
     out.println("<HTML>");
     out.println("<HEAD><TITLE>Hello World</TITLE></HEAD>");
     out.println("<BODY>");
     out.println("<H1>Hello World</H1>");
     out.println("Today is: " + (new java.util.Date().toString()) );
     out.println("</BODY></HTML>");
} // doGet
} // HelloWorld
How can I put this code to run on Sun Java System Web Server, how to compile this ? what and how to put in the webserver document and how to access it ?
Thanks for verbose and basic information about this, appreciated...

What you wrote is not a JSP. It is a Java Servlet.
You need to compile it. That creates HelloWorld.class.
Create a directory say hello. You need to create a directory structure as mentioned below.
hello|
WEB-INF|
web.xml
classes|
HelloWorld.class
You need to package it in a war (web archive) file.
%cd hello
%jar cvf hello.war .
Then deploy this war file using admin GUI or wadm CLI.
I would suggest using Netbeans IDE to create the web application.
To deploy the war file on SJS web server 7 update 2, see my blog at
http://blogs.sun.com/kmeduri/entry/how_to_deploy_a_war

How to read ABAP return parameter into java code

Hi all,
How JAVA environment can trap an error returned from abap code?
E.g.:
From a BAPI wrapper written like this:
"function zpm_gi_create .
""Interfaccia locale:
*" IMPORTING
*"     VALUE(ZBAPIGOODSMVT) TYPE ZBAPIGOODSMVT
*" EXPORTING
*"     VALUE(RETURN) TYPE BAPIRET2

*" TABLES

data: goodsmvt_header type bapi2017_gm_head_01,
        return2         type bapiret2 occurs 0 with header line,
call function 'BAPI_GOODSMVT_CREATE'
    exporting
      goodsmvt_header             = goodsmvt_header
      goodsmvt_code               = zbapigoodsmvt-gm_code
      testrun                     = 'X'
importing

GOODSMVT_SERIALNUMBER       =
      return                      = return2.
Our return (for istance is):
"EBM                  312The (internal) unit xx has not been maintained in
the unit table"
How JAVA environment can trap this error or interpret the BAPIRET2 structure?

Hi elina ,
these topic is already discussed in forum.

Manveer.why do you say this?
My c++ code is:and
In this code we are using some variables. with QT GUI in c++. You didn't code that. Liviu Lalescu code that, not you.
He has rights on that code and he published it under gpl.
So you must say that it is from him, not from you.
Also if you "translate" (modify) his algorithm you must still care about the gpl. Please read whole gpl and care about that.

Where to put java code - Best Practice

Hello. I am working with the Jdeveloper 11.2.2. I am trying to figure out the best practice for where to put code. After reviewing http://docs.oracle.com/cd/E26098_01/web.1112/e16182.pdf it seemed like the application module was the preferred spot (although many of the examples in the pdf are in main methods). After coding a while though, I noticed that there were quite a few libraries imported, and wondered whether this would impact performance.
I reviewed postings on the forum, especially Re: Access service method (client interface) programmatically . This link mentions accessing code from a backing bean -- and the gist of the recommendations seems to be to use the data control to drag it to the JSF, or use the bindings to access code.
My interest lies in where to put java code in the first place; In the View Object, Entity Object, and Am object, backing bean.....other?
I can outline several best guesses about where to put code and the pros and cons:
1. In the application module
Pros: Centralized location for code makes development and support more simple as there are not multiple access points. Much like a data control centralizes services, the application module can act as a conduit for different pieces of code you have in objects in your model.
Cons: Everything in one place means the application module becomes bloated. I am not sure how memory works in java -- if the app module has tons of different libraries are they all called when even a simple query re-execute method is called? Memory hog?
2. Write code in the objects it affects. If you are writing code that accesses a view object, write it in a view object. Then make it visible to the client.
pros: The code is accessed via fewer conduits (for example, I would expect that if you call the application module from a JSF backing bean, then the application module calls the view object, you have three different pieces of code --
conts: The code gets spread out, harder to locate etc.
I would greatly appreciate your thoughts on the matter.
Regards,
Stuart

First point here is when you say "where to put the java code" and you're referring to ADF BC, the point is you put "business logic java code" in the ADF Business Components. It's fine of course to have Java code in the ViewController layer that deals with the UI layer. Just don't put business logic in the UI layer, and don't put UI logic in the model layer. In your 2 examples you seem to be considering the ADF BC layer only, so I'll assume you mean business logic java code only.
Meanwhile I'm not keen on the term best practice as people follow best practices without thinking, typically best practices come with conditions and people forget to apply them. Luckily you're not doing that here as you've thought through the pros and cons of each (nice work).
Anyway, back on topic and off my soap box, as for where to put your code, my thoughts:
1) If you only have 1 or 2 methods put it in the AppModuleImpl
2) If you have hundreds of methods, or there's a chance #1 above will morph into #2, split the code up between the AppModuleImpl, ViewImpl and ViewRowImpls. Why? Because your AM will become overloaded with hundreds of methods making it unreadable. Instead put the code where it should logically go. Methods that work on a specific VO row go into the associated ViewRowImpl, methods that work across rows in a VO go into the ViewImpl, and methods that work across VOs in the associated AppModuleImpl.
To be honest which you ever option you choose, one thing I do recommend as a best practice is be consistent and document the standard so your other programmers know.
Btw there isn't an issue about loading lots of libraries/imports into a class, it has no runtime cost. However if your methods require lots of class variables, then yes this will have a memory cost.
On a side note if you're interested in more ideas around how to build ADF apps correctly think about joining the "ADF EMG", a free online forum which discusses ADF architecture, best practices (cough), deployment architectures and more.

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?

Photoshop or illustrator compositions into edge code

ok so I could have swore I saw someone in an adobe youtube video take an illustrator or photoshop comp and put it into edge code, which in turn wrote the css for him.. it looked like he made what his site should look like in Ai or Ps and then edge code interpreted it into code.. I am a designer and I can write a little code jus not to the extent of what I want the site I;m working on to look like.. is this possible???? or am I losing my mind??

Hi Kurt,
You might be thinking of this: Comp to Code Tool in Brackets – Brackets Blog
However, "PSD Lens" doesn't automatically convert the whole PSD file into CSS for you in one go -- it just helps you extract targeted styles like gradients and background-image assets while you write the larger-scale CSS structure yourself. If you're not very comfortable writing CSS yet (e.g. creating layouts with CSS), you might have a difficult time using this tool. Another option is to import your Photoshop file into Adobe Edge Reflow, use Reflow to create a resizable/responsive layout structure, and then export your project as HTML & CSS.
Hope that helps!

How to run report from java code

I am a begginner in Oracle Reports. We have no AS installed, so we run reports either from Reports Builder or by calling rwrun. I would like to know how to embed report calling into java code , let's say into simple swing application. Some example code would be welcomed. Thanks.

Put ViewObject into scope in Java

I need put ViewObject into scope in Java. For example,
<bc4j:findViewObject name="xxxxView"> (FindViewObjectEventHandler) puts "xxxxView" into scope.
Could I do the same in Java:
ApplicationModule am = (ApplicationModule) context.getProperty(JboConstants.BC4J_NAMESPACE,
JboConstants.APP_MODULE_PROPERTY);
ViewObject vo = am.findViewObject("xxxxView");
and then put it into scope?

Sergey -
Usually, the reason for putting a view object into scope (using <bc4j:findViewObject>) is to make the view object available to other declarative event handlers. If you are writing Java code, then once you obtain a reference to your view object, you should be able to interact with it programmatically - without needing to "put it into scope".
Can you tell me a bit more about the behavior that you are trying to implement? I want to get a better understanding of why you need to put the view object into scope... what UIX code is going to be accessing the view object after you have put it into scope? Where is the Java code that puts the view object into scope being called from (an event handler)?
