Question about variable declaration

Hi all,
I have a (in fact, two) question(s) about the declaration of variables inside of time-critical code, like render loops or similars.
Does it really matter to use
for (int k=0; k<1000; k++)
for (int l=0; l<1000; l++)instead of
int k;
int l;
for (k=0; k<1000; k++)
for (l=0; l<1000; l++)concerning the speed of the app? What about doing this with non-basic types -> Objects, like to say Strings ?
And are there any resources where I can find out more about that and other things like that ?
Uhm, now it became three q's... Sorry to bother you ;-)
Skippy

whoo, maybe I got something totally wrong here.
Does this mean that
Image blah;
for (int i=0; i<100; i++) blah = getImage("test"+i+".gif");will clean up a lot, because there are non-referenced Images and Strings?
Hmm, anyone told me that
for (int i = 0; i<100; i++)
String test = "test"+i;
System.out.println(test);
}is disastrous code.
Damn, ever thought to be a good Java programmer, but every day I get new thoughts I cannot solve these days...

Variable declaration in BEx - Business scenario's

Hi,
I need some documents about all kind of variable declaration with some example business scenarios in MM, FI-CO modules.
will assign you a reasonable points
Regards,
Pooja.S

Hi Pooja,
The processing type of a variable may be varies from business requirement.
In general we will use the processing type:
Replacement Path : If you specify a variable as a characteristic value, you do not have to specify a text for the characteristic value right away. Instead, you can fill the text field dynamically and specifically for the characteristic that you use for the variable when you execute the query. To do this, define a text variable with automatic replacement.
[http://help.sap.com/saphelp_nw70/helpdata/EN/bd/589b3c494d8e15e10000000a114084/content.htm]
Authorisations: If the user belongs to Asia PAciffic region and he must see only details of his region then we can create a variable Region vt Processing type Authorisations so that he vl able to see only that region's data.
[http://help.sap.com/saphelp_nw70/helpdata/EN/44/599b3c494d8e15e10000000a114084/content.htm]
SAP EXIT: If you want to define a query that only ever displays the data from the current month, drag the delivered variable current month (technical name 0CMONTH) for the characteristic calendar year/month (technical name 0CMONTH) into the query filter.
[http://help.sap.com/saphelp_nw70/helpdata/EN/f1/0a5702e09411d2acb90000e829fbfe/content.htm]
Customer Exit: You want to use one characteristic value to calculate a second characteristic value. The InfoProvider only contains the calendar day. However, you now also want to display the cumulated value for the relevant period (beginning with the first day of a quarter) in a query.
For the first day of the quarter, use a variable with customer exit processing. If you now enter the current calendar day (for example, 06/19/2000), a start date of 06/01/2000 appears in the customer exit, and the cumulated value of this period can be displayed.

Binding done at variable declaration

What is difference between
    int x;
    x=5;
and
int x=5;
What are different binding takes place?
How Binding differs in both the cases?
Can anybody please tell me about it.

Hello Tomasz,
welcome in the SAP GUI Scripting forum.
You add at first the SAP GUI Scripting API library as reference to your VBA project from the Tools menu.
Now you can use this code with explicit variable declaration:
Option Explicit
Sub Test()
On Error Resume Next
Dim SapGuiAuto As Object
Dim SAPGUIApp As SAPFEWSELib.GuiApplication
Dim Connection As SAPFEWSELib.GuiConnection
Dim Session As SAPFEWSELib.GuiSession
Set SapGuiAuto = GetObject("SAPGUI")
If SapGuiAuto Is Nothing Then
    Exit Sub
End If
Set SAPGUIApp = SapGuiAuto.GetScriptingEngine
If SAPGUIApp Is Nothing Then
    Exit Sub
End If
Set Connection = SAPGUIApp.Children(0)
If Connection Is Nothing Then
    Exit Sub
End If
Set Session = Connection.Children(0)
If Session Is Nothing Then
    Exit Sub
End If
'Your Code here
End Sub
Good luck.

AddChild / removeChild variables declaration (when is best?)

I am putting together my file right now which is now using visual elements purely added and removed via AS3 (addChild / removeChild) methods. My question is just about the proper time / place to declare their variables.
Can I declare them all at the start of the movie (frame 1) and just call them when I need them, or is it better to declare them on the frames that they are introduced on? I guess the question is really, will I ever lose those variables throughout the movie once they are declared?
thanks.

you won't lose variable declarations. the only thing that could cause a problem was if you referenced an object in a frame where the object doesn't exist. but you can declare variables to have an object types and do not need to point the variables to objects (until later in your code).

Regarding Variables declared i n Subroutine

Hi All,
Can any body give me information about how to capture the data types of Variables declared in Subroutine?

Hi Aruna,
You can use the DESCRIBE command and get the data type of the variables used in the subrotuines.
do a F1 help on DESCRIBE <field> command and you will get more details. DESCRIBE command can be used for tables as well as for the fields.
Cheers

Using a static variable declared in an applet in another class

Hi guys,
I created an applet and i want to use one of the static variables declared in teh applet class in another class i have. however i get an error when i try to do that...
in my Return2 class i try to call the variable infoPanel (declared as a static JPanel in myApplet...myApplet is set up like so:
public class myApplet extends JApplet implements ActionListener, ListSelectionListener
here are some of the lines causing a problem in the Return2 class:
myApplet.infoPanel.removeAll();
myApplet.infoPanel.add(functionForm2.smgframeold);
myApplet.infoPanel.validate();
myApplet.infoPanel.repaint();
here are some of the errors i get
dummy/Return2.java [211:1] package myApplet does not exist
myApplet.infoPanel.removeAll();
^
dummy/Return2.java [212:1] package myApplet does not exist
myApplet.infoPanel.add(functionForm2.smgframeold);
^
dummy/Return2.java [213:1] package myApplet does not exist
myApplet.infoPanel.validate();
^
dummy/Return2.java [214:1] package myApplet does not exist
myApplet.infoPanel.repaint();
^
please help! thanks :)

I don't declare any packages though....i think it just doesn't recognize myApplet for some reason..
other errors i got compiling are:
dummy/Return2.java [82:1] cannot resolve symbol
symbol : variable myApplet
location: class Return2
updateDesc.setString(3, myApplet.staticName);
I Don't get why i'm getting this error cuase they worked fine when myApplet was a standalone application, not an applet.
myApplet is in the same folder as Return2 and it compiles properly.

Why can't I move a variable declaration from inside a Sub to the Declarations area?

I'm writing an app and so far, so good. But I need wider access to an array defined in my "Form_Load" sub.
Private Sub frmMain_Load(sender As Object, e As EventArgs) Handles MyBase.Load
' Assign checkboxes to an array.
Dim Checkboxes() As CheckBox = {chkThumb01, chkThumb02, chkThumb03, chkThumb04, _
chkThumb05, chkThumb06, chkThumb07, chkThumb08, chkThumb09, chkThumb10}
Moving the declaration ("Dim Checkboxes()...") from "Sub frmMain_Load" up into the Declarations space just above it breaks my program. :(
I tried putting it in a Module and that fails too. The ONLY place it work's is in Form_Load (it's not related to being an array because at least one standard integer variable declaration has this problem too.)
I have other variables in the Declarations area that work fine (eg: "Dim bolChanges as Boolean"), but for some reason, I can't move others out into what
should be a more global namespace.
Anyone know what's going on? Thx.

No, because this makes no difference.
Background #1: If you do not write your own constructor (=Sub New), the VB compiler adds a default constructor. It contains a call to Sub InitializeComponent. In this Sub, the controls are created and assigned to chkThumb01 etc. You see it if you type "Sub
New[Enter]":
Sub New()
InitializeComponent()
End Sub
Background #2: If you write
Public Class Test
Private values As Integer() = {1, 2, 3}
End Class
it is identical to
Public Class Test
Private values As Integer()
Sub New()
values = New Integer() {1, 2, 3}
End Sub
End Class
As you can see, the assignments that you do to fields of the class in the declaration line are actually executed in the constructor (sub new).
Now put both backgrounds together. Consequently, this code
Public Class Form1
Private buttons As Button() = {Button1, Button2, Button3}
End Class
is identical to this one:
Public Class Form1
Private buttons As Button()
Sub New()
buttons = New Button() {Button1, Button2, Button3}
InitializeComponent()
End Sub
End Class
Obviously, the assignment to variable "buttons" is done before the call to Sub InitializeComponent. At this point, variables Button1, Button2 and Button3 are still empty (Nothing) because they will be set in Sub InitializeComponent. Consequently,
the array buttons contains just {Nothing, Nothing, Nothing}
In opposite, if the array buttons is set in the Load event, Button1, Button2 and Button3 have already been set before, Consequently, the array buttons correctly contains references to the three buttons.

Why can't i edit the variable declaration in Netbeans GUI Applications?

When i drag and drop jbutton,jlabel and other tools from toolbox on the jform the code is
automatically generated by the Netbeans.
At bottom the variable declaration for the jbutton and for the other tools is automatically
generated.
The part of that declaration is shaded as grey.
Is it possible to edit those variables from Netbeans?

Yup, as Chuck states, it is possible to edit that region of code, since the file is nothing more than a text file, but doing so "breaks" the code so that you cannot modify the GUI content in NetBeans WYSIWYG form editor. Please note, that there are ways of changing the characteristics of those variables without editing them directly. You should look into how to change properties of your GUI with NetBeans. The online tutorials can show you how.

Source a file containing variable declaration in csh style into Java

Hi ALL,
How can java import a plain-text file which contains csh declaration statements, then simultaneously declare as the statements into the java program?
Below is the example that the plain-text file:
set test_1 = ('1')
set test_234 = ('2' '3' '4')
set test_abc = ('abc')
Thanks,
Alex

I have already started learning Java from the web site of Sun Java. Thanks for your advise.
However, let me explain more details what I want.
Now, I have a plain-text file, such as /mnt/source.txt, which contain statement of variable declaration as below
====================
set test_1 = ('1')
set test_234 = ('2' '3' '4')
set test_abc = ('abc')
====================
These are the csh statement.
In csh, we can use command "source [filename]" then the variable test_1, test_234 and test_abc will be declared directly. Right?
Then, now, I have this plain-text file. Also the csh statement.
However, I would use Java to declare the variable test_1, test_234 and test_abc from this file.
Thanks.
Alex

for testing purpose i even removed the cursor and make it shor to above query then also it dosent work and gave the above error . if you know the solution then please let me know . i think i've to do/change database settings but i'm not sure .

the above code is not working but the following code is working if i open cursor from assiging select to variable , why this is happening .

URGENT: problem with variable-declaration while precompiling

          Hi,
          i got a problem while precompiling my webapplication.
          i got some jsp-pages, each containing following code
          <%@ include file="/header.jsp" %>
          <% button = true; %>
          [...some code...]
          <%@ include file="/footer.jsp" %>
          The variable 'button' is defined in header.jsp and
          evaluated in footer.jsp. When i run through my application without precompiling
          it, there appear NO errors, but when i try to precompile my pages, the jsp-compiler
          reports an error in footer.jsp, because in footer.jsp is the 'button'-Variable
          used, but not defined and not included (because all other pages include footer.jsp)
          How can I tell the jsp-Compiler not to check for variable declarations, or what
          else can i do to work around this problem ?
          thanks,
          Dirk Bade


Thanks for the sample. Changed it to look this way. Still getting the error message from above. Any clue?

Documentation about variable types & their processing in i_step = 1, 2 etc.

Hello experts,
is there any documentation about variable types and their processing in i_step = 1, 2 etc.? I know there is note 492504 "Dependent customer exit-type variables", but I don't understand, whether a variable which is NOT "Ready for input" will be processed in i_step = 1 or not (quote of SAP library: "i_step = 1: Call takes place directly before variable entry."). I experienced coincidentally, that some variables not "Ready for input" will be processed there and some not.
Furthermore it is an error, isn't it? Why has a variable without input possibility to be processed before input? Is this really the case?
Confused, any hints are welcomed!
Regards M.L.

for I_STEP = 1
Call before the variable screen .
for I_STEP = 2
Call after variable entry. This step is only started up when the same variable is not input ready and could not be filled at I_STEP=1.
for I_STEP = 3
In this call, you can check the values of the variables. Triggering an exception (RAISE) causes the variable screen to appear once more. Afterwards, I_STEP=2 is also called again.
for I_STEP = 0
The enhancement is not called from the variable screen. The call can come from the authorization check or from the Monitor.
There is a good HOW to Guide which explains the importance of I_STEP :

View of variables declared within a package/procedure

Does anyone know of a view which holds all the variables declared within a package/function/procedure?
I can see that _arguments holds the parameters defined.
PLSQL Developer displays these things in their drop downs, so I assume they are either getting it from a view or have written something which parses the _source view?

Do you mean this ?
