GetParameter() function breaks my loops...

I'm trying to build an array of indices over which to iterate using a WHILE loop. The indices are passed to my java applet from a known parameter name using the function getParameter(that_name).
Once the array is built over which to iterate; I want to get each parameter associated with the param names specified by that array from my HTML and draw the parameter values using drawString() one-by-one.
The array is properly built, the arguments being passed to getParameter are right. The problem is that it stops after only the first iteration of the loop.
Here is my code:
THE JAVA:
import java.applet.*;
import java.awt.*;
import java.lang.Math.*;
import java.lang.String;
import java.lang.reflect.Array;
public class DenGen extends Applet {
@Override
public void paint(Graphics g) {
int radius = 250;
int layers = Integer.parseInt(getParameter("layers"));
int nodes = Integer.parseInt(getParameter("nodes"));
double radii = radius/(layers+2);
boolean String;
String delimeter = ",";
String call = Integer.toString(layers-1);
String make_layer = "00";
String fin = call.concat(make_layer);
String str = getParameter(fin);
String[] final_layer = str.split(delimeter);
int start = 0;
int stop = 0;
int index = 0;
int i = 0;
String param;
while(Integer.parseInt(final_layer) < Array.getLength(final_layer)){
param = getParameter(Integer.toString(i));
g.drawString((String) getParameter(Integer.toString(i)), 250, 10);
i++;
THE HTML:
<html>
<head>
     <style type = text/css>
     .applet{
          border: 1px solid black;
     </style>
</head>

Try this variant. Note that it can be run like this..
prompt>javac DenGen.java
prompt>appletviewer DenGen.java // the '.java' xtn is not a mistake! AppletViewer is smart enough to parse the applet element out of the comment at the top of the file. This is handy for testing purposes, as AppletViewer saves problems with class caching in browsers, and makes the console more easily accessible. It is also handy in that we do not need to create a separate HTML file for it to work. ;)

Calling a function in a loop

Hello,
I have something like this:
         declare
         cursor c is
           select 2,3,4 from dual;
         begin
         for r in c loop
           dbms_output.put_line( prod_stb(81852225, r, 'STB 1 HORECA'));
         end loop;
         end;I wanna call (and output the results) that function in a loop, for all 2,3,4 values for the 2nd parameter.
How can i do this?
with simple 'r' in the 2nd parameter does not work
Thanks!

So the 2nd parameter should be 2,3 and 4 (in a loop).Well, as far as I understand, that's exactly what you'll get:
SQL> begin
2    for r in ( select level+1 col from dual connect by level <= 3 )
3    loop
4      dbms_output.put_line( r.col);

Functions in a Loop

I'm trying to create multiple Functions inside a Loop. Can I not do this?
for (var i:Number = 1; i<5; i++)
function this["closeButOut"+i](event:MouseEvent)
closeBar["but0" + i].gotoAndStop(1);
I essentially want to make 4 Functions called closeButOut1, closeButOut2, closeButOut3 and closeButOut4.
This is the error message I get:
1084: Synax error: expecting identifier before this.
1084: Syntax error: expecting leftparen before rightbracket.

Sorry, it should look like this:
for (var i:Number = 1; i<5; i++)
closeBar["but0" + i].addEventListener(MouseEvent.ROLL_OUT, this["closeButOut"+i])
function this["closeButOut"+i](event:MouseEvent)
closeBar["but0" + i].gotoAndStop(1);
When I tried your change, it seemed to accept it, but the listener doesn't recognize it as the same function it's looking for.

How to use select a vi function inside a loop?

I am modifying the notifier basics part 2.vi to send a notifier to each of 64 sub-vi's. How can you use the 'select a vi' function inside a loop for 64 iterations to access the individual filenames??
Attachments:
Notifier_BASICS_Part_2.vi ‏87 KB

If all you are trying to do is send notifiers to each of these 64 subVIs, I would suggest not doing it in a loop, but rather just placing the 64 subVIs in your diagram.
The alternative is of course to use the call by reference node and have an array of VI names. This is a little cleaner on the diagram, but 1) doesn't occur in parallel and 2) is a bit tricky. Additionally, you have to be sure that your array of filenames is correct, and that you NEVER move or rename those VIs. Of course, you could always put them in a directory and create an array by reading the directory contents.
Either way, good luck, it doesn't sound like fun.

Edited by: Thomas Zloch on Mar 15, 2011 9:06 AM

Hi Sanket,
You need to have three tables of type IT_OUTPUT,
1) One which will have the input values that you need to pass to the BAPI - IT_OUTPUT_IN.
2) The second table to get the out from the BAPI - IT_OUTPUT_OUT.
3) The third table to accumulate the output from the BAPI - IT_OUTPUT_FINAL.
change the code as given below,
LOOP AT IT_OUTPUT_IN INTO WA_OUTPUT .
CALL FUNCTION 'BAPI_GL_GETGLACCPERIODBALANCES'
EXPORTING
COMPANYCODE = WA_OUTPUT-BUKRS
GLACCT = WA_OUTPUT-HKONT (A/C NO)
FISCALYEAR = WA_OUTPUT-GJAHR
CURRENCYTYPE = '10'
IMPORTING
BALANCE_CARRIED_FORWARD =
RETURN =
TABLES
ACCOUNT_BALANCES = IT_OUTPUT_OUT.
append lines of IT_OUTPUT_OUT to IT_OUTPUT_FINAL.
REFRESH: IT_OUTPUT_OUT.
ENDLOOP.
With your current code: You are overwriting the entries of IT_OUTPUT every time you are calling the BAPI, and re-using the same entries in the loop.

GetParameter function in 1.4.1

Hi,
I want to get parameters from an applet.
The parameter's value contains carriage return. When I use the getParameter() function, all the carriage return are deleted. The problem is that I need them !
Below a kind of parameters I used :
<PARAM NAME="USER_TXT" VALUE="<B>title 1</B><br>
4685006|GV2L|LC1D25/32|LR2DZ3|6
4686506|GS1F|LC1D09/12/18|LR2Z13|6
">
The Java code I used:
strTxt= parent.getParameter("USER_TXT");
The string displayed in the Java Console:
<B>title 1</B><br>4685006|GV2L|LC1D25/32|LR2DZ3|64686506|GS1F|LC1D09/12/18|LR2Z13|6
It worked fine when I used the 1.3.1_01 JVM but it does not work in 1.4.1_01....
Does anyone have a solution to get the value with the carriage return?
Thank you for your help,
Scrb.

How about encoding your CRs somehow? Try using the unicode escape sequence for CR, \u000D or maybe even the Java/C-style \n.

How to define function within for loop pls help?????

Hi this is the problem i have a class, and within that class there is an actionPerformed function, in this class i also create an instance of another class, this other class also contains an actionPerformed function, which wis executed if a jButton has been pressed, when I try to place this actionPerfromed function within a for loop of a function i get an error saying illegal start of experssion, and that the class should be defined abstract as it does not define actionPerformed, when i take it out of the for loop it compliles fine, i need the function to be placed within the for loop because it needs to know the variable of the for loop, is there anyway around this? Thanks, below is the code:
public class DisplayTransitions extends JFrame implements ActionListener
public void add()
for(int i = 0; i < char2.size(); i ++)
mPanel.add(tim[i] = new JButton("Time"));
tim.addActionListener(this);
public void actionPerformed(ActionEvent ae)
     if (ae.getSource() == tim[i])
          timeIncr();

This is your for loop using an anonymous inner class for the listener:
            for (int i = 0; i < char2.size(); i++) {
                mPanel.add(tim[i] = new JButton("Time"));
                tim.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent ae) {
if (ae.getSource() == tim[i]) {
timeIncr();
Learn more about anonymous inner classes from a good Java book or the Java tutorial (try http://java.sun.com/docs/books/tutorial/java/javaOO/QandE/nested-answers.html).

Opening PDF in IE "breaking" for loop

Hi,
I have a dynamic PDF that is uploaded to a website. When the PDF opens, the user has to fill in certain fields before clicking the "Next" button. Upon clicking the Next button, I have a JavaScript function that sets certain fields access to required and then runs a for loop to check if any are empty. The next event is setting those fields access back to optional. Lastly, a popup window refers the user to the empty fields (fields are shaded red, but not their borders).
The problem occurs for one user who is using IE9 and has Reader X installed on his machine. It only occurs when he opens it directly with his browser, if he downloads it to his desktop first he encounters no problem. But using the browser makes filling in the fields on Page 1 glitchy, and then the loop doesn't work properly when he hits "Next". The event setting the fields back to optional doesn't seem to be firing, and the popup never comes up. So he's left with fields with red borders-which should not be happening.
Any idea what could be causing this bug only when accessing via browser? I can't replicate the problem on any of my browsers, even after disabling Adobe add-ons in IE.
Thanks for any suggestions!

Performance issue: CALL FUNCTION inside a Loop.

Hi Friends
I have a Performance Issue. That is, inside a loop...endloop a CALL FUNCTION has been used which gets data from another database table. Finally it's appended into another internal table. Please see this :
LOOP AT i_mdkp.
    REFRESH lt_mdtbx.
    CLEAR lt_mdtbx.
    CALL FUNCTION 'READ_MRP_LIST'
      EXPORTING
        idtnum        = i_mdkp-dtnum
        icflag        = 'X'
      tables
        mdtbx         = lt_mdtbx
    APPEND LINES OF lt_mdtbx TO i_mdtb.
ENDLOOP.
It happens for each record available in i_mdkp. Suppose, i_mdkp have around 50000 records, it needs to call the function module till that much time.
So, I want to split it. Can I?
Please give me your valueable suggestions.
Regards
Senthil

If internal table i_mdkp has 50,000 records it does not mean that you need to run 50,000 iterations. You just need dtnum from internal table i_mdkp so you number of iterations should be eqaul to the unique number of dtnum in the internal table. Sort the internal table by dtnum and delete adjacent duplicates from the internal table comparing dtnum before looping. Look at the code below.
DATA i_mdkp_tmp LIKE TABLE OF i_mdkp.
IF NOT i_mdkp[] IS INITIAL.
i_mdkp_tmp[] = i_mdkp[].
SORT i_mdkp BY dtnum.
DELETE ADJACENT DUPLICATES FROM i_mdkp COMPARING dtnum.
REFRESH i_mdtb.
LOOP AT i_mdkp.
    CALL FUNCTION 'READ_MRP_LIST'
      EXPORTING
        idtnum = i_mdkp-dtnum
        icflag = 'X'
      TABLES
        mdtbx = lt_mdtbx.
    APPEND LINES OF lt_mdtbx TO i_mdtb.
    REFRESH lt_mdtbx.
ENDLOOP.
i_mdkp[] = i_mdkp_tmp[]
ENDIF.

Function with for loop and parameter table/column names ... syntax help

I'm trying to create a function that returns the distinct values and counts from a user defined schema/table/column.
The code below defines an object type [stats_on_column_obj] and creates a single table of this type [stats_on_column_tab].

Rank function breaks drill down 11g

I have a simple drill down report standard hierarchy and am having a weird issue with the rank function.
This report works on 10g but the upgraded 11g version does not.
When I drill down past the 2nd level it adds an is null filter to the revenue column. This is also the column we are using to base our rank function.
If I move the rank column to the first or last position in the table the drills work perfectly. If I move it to the second column it breaks on the first drill instead of the 2nd.
It works perfectly if drilling on the headings instead of the values. That seems to point to some sort of null coming through when being passed. I've tried using an ifnull and a case statement and neither method works, it just applies the is null filter to the entire column formula.
The client doesn't want to change the position of the rank column so that work around will not do. Any ideas?

A similar thread was recently talked about here:
In OBIEE charts, how do you make drill downs work on custom formulas?
With a calculated column, you need to make sure the source query and destination query have the EXACT same formula and the same name for the field. If it is not 100% identical, it may not work correctly. (I typically use the NAVIGATE function to get to the second query rather than the Drill function.)
Now in some cases, if you try to create a second drill down query with more details in it, the original formula doesn't work the way you want it to. The calculated formulas have to make sense in both source query and destination query in order to work properly. If you have a ranking of the Top 5 Products in the source query, the destination query also has to have the same ranking of Top 5 products in order to work. If you add more fields into the destination query (e.g., adding on product attributes, or # of records associated with that product name etc.), then sometimes the ranking / aggregation in the destination doesn't add up the same way. This causes the system to think that the formulas are different and prevents the drill down.
I managed to get around this by having a 3rd query in between the original summary view and the detailed data view. So the sequence would be (for example):
- Dashboard based summary query (including the calculated ranked product names formula)
- drill down into virtually identical query (add on one slight bit of difference here, for example adding on a second Product Name field ... not a calculated version, but the actual name). Create a drill down this time by clicking on the regular Product Name field (don't drill down on the custom formula)
- final detailed drill-down query
You can format this intermediary drill down query to explain to users that they need to click a second time.
It's not ideal, but it should work. Hope this helps.

Using the Wait function in while loops?

Hi,
I have a rather complicated top level VI with about 20 subVIs and the main VI has on big while loop around it and another smaller one inside, basically it runs rather slow and I have no idea how to set the wait function. I mean what factors should I consider..what would be the difference between setting it to 10 and 100 (besides the obvious 10ms vs 100ms)? I just want to increase the performance of the executable, so it is not that slow. Can you offer some hints as to what I need to take into consideration when determining my delay? And also, are while loops the only place that I should use the delay or are there other instances too?

Adding waits is not a fix-all for slow running applications. Its just one thing that can be done to improve things. If you determine that a sub-vi is causing your problems then you need to find out exactly what that vi is doing to slow you down. If its because there is a loop inside it that is running constantly as fast as it can, then a delay in that loop may help. If that is not your problem then you need to look at other ways to boost performance. It sounds like you have alot of locals variables, each instance of a local variable makes a copy of the data that's in the control. If the controls/indicators that you have local variables of contain large amounts of data then you may be filling up memor
y with copies of it.
I suggest that you study the "Performance and Memory Management" chapter of the LabVIEW manual. This can found in the printed manual of the older versions, in the online manuals that install with 6i, or on NI's web site here: http://zone.ni.com/devzone/conceptd.nsf/2d17d611efb58b22862567a9006ffe76/732cec772aa4fbe586256a37005541d3?OpenDocument , which is Application Note 168. This should give you some good ideas of what to look for to improve your performance.
Hope this helps.
