Saving 3 sets of data in 3 seperate arraylist and passing them to next view

Hai all,
I am using tree.The user has selected the required products in level 3 of tree.Iam getting all the parents of selected product.In order to save them in database i need to send them to next view.how to store all the 3 levels in seperate arrays and pass them to next view.Plz help me with coding.Any suggesstions and help with regard to this will be greatly appreciated.
Thanks n Regards

hi,
1. just collect all the values and concatinate using Strings, also use one delimiter between each value.
like this,
while(condition){
String Result ="";
Result += wdContext.currentTreeNode().getName() + "," ;}
2. Finally assign this String to some Context, that you want to use in next view.
3. Use StringTokenizer Class, make Result String as Source and comma as delimeter, then you can able to get list of
previously stored values.

Retrieving data from an ArrayList and presenting them in a JSP

Dear Fellow Java Developers:
I am developing a catalogue site that would give the user the option of viewing items on a JSP page. The thing is, a user may request to view a certain item of which there are several varieties, for example "shirts". There may be 20 different varieties, and the catalogue page would present the 20 different shirts on the page. However, I want to give the user the option of either viewing all the shirts on a single page, or view a certain number at a time, and view the other shirts on a second or third JSP page.
See the following link as an example:
http://www.eddiebauer.com/eb/cat_default.asp?nv=2|21472|9&tid=&c=&sc=&cm_cg=&lp=n2f
I am able to retrieve the data from the database, and present all of them on a JSP, however I am not sure how to implement the functionality so that they can be viewed a certain number at a time. So if I want to present say 12 items on a page and the database resultset brings back 30 items, I should be able to present the first 12 items on page1, the next 12 items on page2, and the remaining 6 items on page3. How would I do this? Below is my scriplet code that I use to retrieve information from the ArrayList that I retrieve from my database and present them in their entirety on a single JSP page:
<table>
<tr>
<%String product=request.getParameter("item");
ArrayList list=aBean.getCatalogueData(product);
int j=0, n=2;
for(Iterator i=list.iterator(); i.hasNext(); j++){
if(j>n){
out.print("</tr><tr>");
j=0;
Integer id=(Integer)i.next();
String name=(String)i.next();
String productURL=(String)i.next();
out.print("a bunch of html with the above variables embedded inside")
%>
</tr>
</table>
where aBean is an instace of a JavaBean that retrieves the data from the Database.
I have two ideas, because each iteration of the for loop represents one row from the database, I was thinking of introducing another int variable k that would be used to count all the iterations in the for loop, thus knowing the exact number. Once we had that value, we would then be able to determine if it was greater than or less than or equal to the maximum number of items we wanted to present on the JSP page( in this case 12). Once we had that value would then pass that value along to the next page and the for loop in each subsequent JSP page would continue from where the previous JSP page left off. The other option, would be to create a new ArrayList for each JSP page, where each JSP page would have an ArrayList that held all the items that it would present and that was it. Which approach is best? And more importantly, how would I implement it?
Just wondering.
Thanks in advance to all that reply.
Sincerely;
Fayyaz

-You said to pass two parameters in the request,
"start", and "count". The initial values for "start"
would be zero, and the inital value for "count" would
be the number of rows in the resultSet from the
database, correct?Correct.
-I am a little fuzzy about the following block of code
you gave:
//Set start and count for next page
start += count; // If less than count left in array, send the number left to next next page
count = ((start*3)+(count*3) < list.size()) ? (count) : ((list.size() - (start*3))/3)
Could you explain the above block of code a little
further please?Okay, first, I was using the ternary operators (boolean) ? val_if_true : val_if_false;
This works like an if() else ; statement, where the expression before the ? represents the condition of the if statement, the result of the expression directly after the ? is returned if the condition is true, and the expression after the : is returned if the condition is false. These two statments below, one using the ternary ? : operators, and the other an if/else, do the same thing:
count = ((start*3)+(count*3) < list.size()) ? (count) : ((list.size() - (start*3))/3);
if ((start*3)+(count*3) < list.size()) count = count;
else count = ((list.size() - (start*3))/3);Now, why all the multiplying by 3s? Because you store three values in your list for each product, 1) the product ID, 2) the product Name, and 3) the product URL. So to look at the third item, we need to be looking at the 9th,10th, and 11th values in the list.
So I want to avoid an ArrayIndexOutOfBounds error from occuring if I try to access the List by an index greater than the size of the list. Since I am working with product numbers, and not the number of items stored in the list, I need to multiply by three, both the start and count, to make sure their sum does not exceed the value stored in the list. I test this with ((start*3)+(count*3) < list.size()) ?. It could have been done like: ((start + count) * 3 < list.size()) ?.
So if this is true, the next page can begin looking through the list at the correct start position and find the number of items we want to display without overstepping the end of the list. So we can leave count the way it is.
If this is false, then we want to change count so we will only traverse the number of products that are left in the list. To do this, we subtract where the next page is going to start looking in the list (start*3) from the total size of the list, and devide that by 3, to get the number of products left (which will be less then count. To do this, I used: ((list.size() - (start*3))/3), but I could have used: ((list.size()/3) - start).
Does this explain it enough? I don't think I used the best math in the original post, and the line might be better written as:
count = ((size + count)*3 < list.size()) ? (count) : ((list.size()/3) - start);All this math would be unnecessary if you made a ProductBean that stored the three values in it.
>
- You have the following code snippet:
//Get the string to display this same JSP, but with new start and count
String nextDisplayURL = encodeRedirectURL("thispage.jsp?start=" + start + "&count=" + count + "&item=" + product);
%>
<a href="<%=nextDisplayURL%>">Next Page</a>
How would you do a previous page URL? Also, I need to
place the "previous", "next" and the different page
number values at the top of the JSP page, as in the
following url:
http://www.eddiebauer.com/eb/cat_default.asp?nv=2|21472
9&tid=&c=&sc=&cm_cg=&lp=n2f
How do I do this? I figure this might be a problem
since I am processing the code in the middle of the
page, and then I need to have these variables right at
the top. Any suggestions?One way is to make new variable names, 'nextStart', 'previousStart', 'nextCount', 'previousCount'.
Calculate these at the top, based on start and count, but leave the ints you use for start and count unchanged. You may want to store the count in the session rather than pass it along, if this is the case. Then you just worry about the start, or page number (start would be (page number - 1) * count. This would be better because the count for the last page will be less than the count on other pages, If we put the count in session we will remember that for previous pages...
I think with the details I provided in this and previous post, you should be able to write the necessary code.

Thanks once again for all of your help, I really do
appreciate the time and effort.
Take care.

How to decode a set of datas received from serial port and display image on a canvas based on CVI ?

Hi !
I have received a set of datas via rs232 and it contains picture messages. I have to decode the datas first and then display them on a canvas.
I have known several functions that may be used . Such as
int SetBitmapData (int bitmapID, int bytesPerRow, int pixelDepth, int colorTable[], unsigned char bits[], unsigned char mask[]);
int CanvasDrawBitmap (int panelHandle, int controlID, int bitmapID, Rect sourceRectangle, Rect destinationRectangle);
However,I don't know how to set the following parameters according to the actual pixel values and color values.
int bytesPerRow, int pixelDepth, int colorTable[], unsigned char bits[], unsigned char mask[]
What's more,I have no idea how to decode the datas.
The attachment is a incomplete project. I will be very appreciated if anyone could help me .
Best regards.

I wouldn't care success or failure,for I will only struggle ahead as long as I have been destined to the distance.

Decode and display image.zip ‏212 KB

Well, things are getting a bit clearer now.
1. Your image is actually 240x240 pixel (not 320x240 as you told before). The size of image data is 57600 bytes which corresponds to that frmat (I was puzzled by such a data size compared with larger image dimensions!)
2. The image is a 8-bits-per-pixel one; this means that you must provide a color palette to create the bitmap
3. You cannot simply copy image data into bitmap fields in CVI: CreateBitmap always produce an image with pixeldepth matched with display colour depth (normally 24 or 32 bpp)
All that means that you must:
1. Create the appropriate color palette with 256 colors: it may be a grayscale or color palette depending on camera characteristics. Grayscale palette can be found in my sample project, while sample colour palettes can be found here (here the description of a "standard" 8-bpp color palette)
2. Create the bits array correctly dimensioned for the color depth of your monitor
3. Get each pixel value from the camera, lookup in the color palette for the appropriate colour and create the RGB informations into the bits array in memory
4. Display the bitmap on the canvas
As a first step, I would configure my system for 256-color display setting, create a bitmap and simply copy image data into it: you should be able to get the correct image back to your screen.
Proud to use LW/CVI from 3.1 on.

How can I get Firefox to stop saving the open tabs when it closes and reinstating them the next time it opens?

Even tho' I've set options for Firefox to delete history when it closes, it still remembers my open tabs and tries to reinstate them the next time it starts. This causes two problems: 1) it takes longer for Firefox to close, such that if I start it again a few sec later it is still running and won't restart; 2) it sometimes reopens websites I am no longer want when it next starts. The latter also makes the last sites I visited visible to the next user, which I (and I suspect most other users) want to avoid. I would like to turn this feature off since it is far more of a problem than a benefit!

@cor-el
I have the same problem.
My settings are already configured to "Show a blank page". It does show a blank page normally, but when FF crashes, it attempts to reload all the tabs from the previous session when it restarts. My version is: Firefox/3.6.13, and I'm running XP sp3 if that matters.

How to sort data in PL/SQL table and print them in Order?

Hi Guys
I wan to create a csv file layout as below, maximum we got 12 weeks sales figure for each item. Week is week of the year, it will different every time based on sales_date.
Item Number     Description     Sales Week      27 26 25 24 23 22 21 20..
1234          Sample                10     6     2     8     10
1230          Test                50     60     2      10
I got item number, description, week_no and sales in a temp table which is populated by a procedure. Now I need to write these records from table to a file.
I not sure how to store multiple records for each item in PL/SQL table, sort them and print them in above format.
My select statement is as below
select item_number,
description,
week_no,
year,
opening_stock_qty,
production_qty,
sales_qty,
creation_date,
(production_qty - sales_qty) net_qty
from xxsu_planning_report
order by item_number,year,week_no;
Any help will be much appreciated.
Thanks and regards
VJ

Above error occured because you are trying to concatenate dbms output with some other string, which is not allowed.
Declare
TYPE plan_type IS TABLE OF xxsu_planning_report%ROWTYPE
INDEX BY BINARY_INTEGER;
plan_table plan_type;
BEGIN
plan_table(1).week_no := 24;
plan_table(1).description := 'This is week 24';
plan_table(2).week_no := 21;
plan_table(2).description := 'This is week 21';
for i IN 1..2 loop
dbms_output.put_line(plan_table(i).week_no) || ' ' || plan_table(i).description);
end loop;
END;From your code, I didnt understood what you want to do. Using Associative Array would be wrong approach in this case.
As per your scenario, you have to store max 12 records for each item number.
create or replace type dailySales as object(Description varchar2(100), Sales number, Week number);
create or replace type saletab as table of dailySales;
create table t_sales (p_item number, p_sales saletab);
insert into t_sales values
(p_item, ---------enter value for item number 1
saletab(dailySales($n1,$n2,$n3)), ---------enter value for sales record for week 1
saletab(dailySales($n1,$n2,$n3)), ---------enter value for sales record for week 2
saletab(dailySales($n1,$n2,$n3)), ---------enter value for sales record for week 3
saletab(dailySales($n1,$n2,$n3)), ---------enter value for sales record for week 4
saletab(dailySales($n1,$n2,$n3)), ---------enter value for sales record for week 5
saletab(dailySales($n1,$n2,$n3)), ---------enter value for sales record for week 6
saletab(dailySales($n1,$n2,$n3)), ---------enter value for sales record for week 7
saletab(dailySales($n1,$n2,$n3)), ---------enter value for sales record for week 8
saletab(dailySales($n1,$n2,$n3)), ---------enter value for sales record for week 9
saletab(dailySales($n1,$n2,$n3)), ---------enter value for sales record for week 10
saletab(dailySales($n1,$n2,$n3)), ---------enter value for sales record for week 11
saletab(dailySales($n1,$n2,$n3)) ---------enter value for sales record for week 12
Enter 0 if no sales exist for any week. Because NULL would throw an exception.
Execute the SQL query to check the output.Try this and let me know if any fyrther issues.

How can I set the data binding between Web Dynpro & Database table

Dear friend,
I am a beginner of Web Dynpro. I want to develop my simple project like these:
1. Create my own database table via Dictionary Project such as TAB_USER and have 3 fields: USER_ID, USER_NAME, USER_POSITION and I have already deployed & archived it.
2. Create my own Web Dynpro Project, and create the input fields as User ID, User name, User position and icon 'Save' on the selection screen and I have deployed it already.
For the process, I want to input data at the screen and save the data in the table, please give me the guide line like these:
1. How can I set the data binding between Web Dynpro and Database table ?
2. Are there any nescessary steps that I will concern for this case?
Sorry if my question is simple, I had try to find solution myself, but it not found
Thanks in advances,
SeMs

Hi,
You can write your own connection class for establishing the connection with DB.
Ex:
public class ConnectionClass {
static Connection con = null;
public static Connection getConnection() {
try{
Context ctx = new InitialContext();
DataSource ds = (DataSource) ctx.lookup("jdbc/TSPAGE");
con = ds.getConnection();
return con;
}catch(Exception e){
return null;
You can place the above class file in src folder and you can use this class in webdynpro.
You can have another UserInfo class for reading and writing the data into the DB .

How to save data in a 4D array and make partial plots in real time?

Hi, this is a little complex, so bear with me...
I have a test system that tests a number of parts at the same time. The
experiment I do consists of measuring a number of properties of the
parts at various temperatures and voltages. I want to save all the
measured data in a 4-dimensional array. The indices represent,
respectively, temperature, voltage, part, property.
The way the experiment is done, I first do a loop in temperature, then
in voltage, then switch the part. At this point, I measure all the
properties for that condition and part and want to add them as a 1D
array to the 4D array.
At the same time, I want to make a multiple plot (on an XY graph) of
one selected property and part (using two pull-down selectors near the
XY graph) vs. voltage. (The reason I need to use an XY graph and not a
waveform graph, which would be easier, is that I do not have
equidistant steps in voltage, although all the voltage values I step
through are the same for all cases). The multiple plots are the data
sets at different temperatures. I would like to draw connection lines
between the points as a guide to the eye.
I also want the plot to be updated in the innermost for loop in real
time as the data are measured. I have a VI working using nested loops
as described above and passing the 4D array through shift registers,
starting with an array of the right dimensions initialized by zeroes. I
know in advance how many times all the loops have to be executed, and I
use the ReplaceArraySubset function to add the measured properties each
time. I then use IndexArray with the part and property index terminals
wired to extract the 2D array containing the data I want to plot. After
some transformation to combine these data with an array of the voltage
values in the form required to pass to the XYGraph control, I get my
plot.
The problem is: During program execution, when only partial data is
available, all the zero elements in the array do not allow the graph to
autoscale properly, and the lines between the points make little sense
when they jump to zero.
Here is how I think the problem could be solved:
1. Start with an empty array and have the array grow gradually as the
elements are measured. I tried to implement this using Insert Into
Array. Unfortunately, this VI is not as flexible as the Replace Array
Subset, and does not allow me to add a 1D array to a 4D array. One
other option would be to use the Build Array, but I could not figure
out if this is usable in this case.
2. The second option would be to extract only the already measured data
points from the 4D array and pass them to the graph
3. Keep track of the min. and max. values (only when they are different
from zero) and manually reset the graph Y axis scale each time.
Option 3 is doable, but more work for me.....
Option 2: I first tried to use Array Subset, but this always returns an
array of the same dimensionality of the input array. It seems to be
very difficult, but maybe not impossible, to make this work by using
Index Array first followed by Array Subset. Option 3 seems easier.
Ideally, I would like option 1, but I cannot figure out how to achieve
this.
Your help is appreciated, thanks in advance!

I love autoscaling, that's the way it should be.

Lost IPTC meta data on TIFF import -- old and unsolved problem?

Hi,
this is my first post, after using Aperture on a casual basis for 7 months.
Browsing the forum I found the same problem in older threads but the solutions do not help in my case: When I export pictures with IPTC I set in Graphic Converter, metadata will be imported from the RAW (NEC from a Nikon D80) and from JPEG files, but not from the TIFF, whatever encoding or byte order I choose.
Any help in that matter?
Thanks,

You didn't say which version of Aperture you are using. Up until the recent updates I found Aperture missed, or cut off, a log of IPTC data when I imported RAW files. This seems to be solved with the current version, but ratings still don't get imported.
I used Annoture (http://www.tow.com/annoture/) to copy over the data. I would import the images into Aperture, then also into iView Media Pro. I'd select all the images in Aperture and then run Annoture. Annoture would take all the IPTC data from the iView catalogue and copy them to the selected images in Aperture (also works on selected projects I think).
It's a long winded solution, but did the job.

How to seperate a certain set of data..?

Hi everyone. I am making a measurement. In this measurement there are let say 1000 value. I want to take 100 specific value for further analysis. For this, I want to index those data which I want and calculate them, then continue doing next measurement.
Let say, I am measuring voltage at every 100K temperature. As you can see from the picture. At 100K I am measuring voltage likte this. Here what I want is to take this data which is red to calculate something. I am looking forward your ideas. Best and thanks in advance.

there is my vi. what I want to do is; there are two temperature values. I set both of them to the specific temperature value, and wait for the stability. As stability achieved, set one of the temperature again; here my measurement starts, measure the dT and dV simultaneously. As the temperature level achieved the same level, stop the measurement and index these dV and dT to calculate.
example;
set T1=300K, T2=300K, as they are stable
set T1=305K, T2=300K, start recording dV and dT and AverageT
as T1=305K =>>set T!1=300K; continue recording dV and dT and AverageT
as T1=300K, T2=300K, stop recording, set new temperature.
Best.
