Dynamically creating number of bars in a histogram

Post Author: oradba101
CA Forum: Charts and Graphs
Greetings,
A user would like to be able to selct thw number of bars to display in a histogram chart, The y-axis consistd of incremntal numbers that can vary based upon the criteria a user selects.
I was thinking along these lines:
1. Create a paramete in which the user can select a number from 3 -13 (number of bars they want to see)
2. Pass the parameter to a running total object and have it do - (max(y-axis) - min(yaxis)) / parameter.
I hope I explained this well enough and yhanks in advance for your help

I suppose the first question would be; how would you do this manually in the CR designer? The try to mimic the same steps at runtime. You do not mention version of CR (I suspect it is the .NET 2005 bundle?). Your description implies that you essentially want to build the table at runtime. E.g.; report creation APIs which are not available in the .NET 2005 bundle. Stand-alone versions of CR include RAS APIs and you can use those to build the report or parts of the report such as a table at runtime.

Dynamically create varying number of buttons

Hi.
The website I'm currently working on has an object gallery.
Whenever the user clicks one of the objects, it zooms in and
displays a sub-gallery with other images of said object. The images
that make up these galleries are loaded into dynamically created
empty MovieClips inside a sub-gallery MovieClip. Each object has a
varying number of images and they're loaded and unloaded when the
zooming in/out of the object ends.
When you click one of the sub-gallery images, the main image
should change and display the clicked image. However, I'm having
trouble telling the MovieClips containing the sub-gallery images to
do anything when they're clicked. See attached code, please.
I'm guessing this has to do with the onRelease being declared
inside the onMotionFinished. The thing is I can't thing of a way to
declare the onRelease for every sub-gallery image before they're
loaded.
Thanks in advance.

Frank,
Thank you for the response.
On the page2 of the pdf link you provided there is a picture of the tree table and it shows the hierarchy of the first level(or root) parent (President, Steven King). If the data had n presidents (n first or root level ) then this will dispaly all data in the same tree table like
King
--Kochhar
----Greenberge
King 2
--report 1
----report 1.1
King n
--report n
----report n.1
My requirement is pretty close to this but slighly different where these n first level should appear in n different tree tables like below:
Treetable for: King
King
--Kochhar
----Greenberge
Treetable for: King 2
King 2
--report 1
----report 1.1
Treetable for: King n
King n
--report n
----report n.1
That is the reason why I am playing with af:forEach and also have a separate VO which returns all the presidents(first level parents) and view linked that to EmployeesVO so that the AM looks like
AllPresidentsVO
-----EmployeesVO (with the view criteria wihch returns the first level parents)
---------reportingManagers
forEach prints n instances for PresidentsVO King, King2.. King n but all these instances have the same children the tree for King (tree for King2 ... King n does not appear)
May be it should be achieved in a different way?

How to dynamic create Splitter Bars

I'm confused by the title of this question. What is it that you want to do dynamically?
Hi Michael,
May be I'm wrong (as you can notice my mother tongue is not English) but my interpretation of Mike's question is "What are splitter bars ?" and not "How can I dynamically add a splitter bar to a FP ?" Only Mike could confirm if this was his original question...
Unfortunately, I don't know how to create a splitter bar programatically, and even more, I'm afraid that this is not possible. So my aim was only to answer to what seemed to be the source of Mike's confusion.
This being said, I hope that Mike's and your confusion left !

How do I reference a dynamically created MovieClip from another MovieClip?

Hi,
I'd be grateful for any pointers to the following problem:
     I'm having trouble referencing dynamically created MovieClips (links in a side panel on a Flash website, created from an XML file) from the current MovieClip (the currently selected link).
     I wish to freeze the the link/MovieClip in its mouseOver state once it has been clicked - this part works. When a new link/MovieClip is clicked on, I wish to release the previously clicked-on link from its mouseOver state, which is what I've so far been unable to do.
     My problem seems to be referencing the previous link/MoveClip. I've used the trace statement trace(MovieClip(this).name) to determine that the MovieClips are named item0, item1, item2 and so on. However, I've been unable thus far to reference the previous clip thus far. I've tried to trace the route to the MovieClip from the stage, and also tried MovieClip(parent).item0.gotoAndStop and lots of other different permutations, but to no avail. It's the fact they seem to be in a container called 'panel' which is defeating me.
     Here's a live version I've uploaded, which might explain the problem better. Click on "UBER UNS" in the top menu bar to get to the page in question. It's the links on the left-hand side (Historie, Unser Team, etc.) which are the problem. You'll see that once they've been clicked on they remain in their mouseOver state.
     This is the code in question on the fla file, which is a file I did not create myself. The parts in black work fine; it's the red parts where the problem lies:
import flash.display.MovieClip;
panel.buttonMode = true;
var lang:uint = 1;
var url_Link:String=MovieClip(root).program.websiteXML .language[lang].pages.titlePage[MovieClip(root).program.linkPage].texts.pageList.txt[numT XT].@link;
var urlPage:Number=Number(MovieClip(root).program.webs iteXML.language[lang].pages.titlePage[MovieClip(root).program.linkPage].texts.pageList.tx t[numTXT].@linkPage);
var request:URLRequest;
var linkIndex:uint;
var lastClickedLink:MovieClip;   //This is supposed to store the last link that has been clicked - it doesn't work
panel.addEventListener(MouseEvent.CLICK, clicLink);
panel.addEventListener(MouseEvent.ROLL_OVER, mouseOverLink);
panel.addEventListener(MouseEvent.ROLL_OUT, mouseOutLink);
function mouseOverLink(event:MouseEvent):void {
      MovieClip(this).gotoAndPlay('s1');
function mouseOutLink(event:MouseEvent):void {
      if(numTXT !== (linkIndex - 1)/5){         //freezes mouseOver state if this is the link for the current page
           MovieClip(this).gotoAndPlay('s2');
function clicLink(event:MouseEvent):void {
      var linkpage:uint = MovieClip(root).program.linkPage;
      if (url_Link) {
           request = new URLRequest(url_Link);
           navigateToURL(request);
      } else {
           linkIndex = numTXT * 5 + 1;
           if(linkpage == 1){
               MovieClip(root).chPages.cont.page_about_mc.page3Tu rner_mc.gotoAndStop([linkIndex]);
          } else if (linkpage == 2){
               MovieClip(root).chPages.cont.page3_mc.page3Turner_ mc.gotoAndStop([linkIndex]);
     lastClickedLink.gotoAndPlay('s2'); // this is supposed to release the previous clicked-on link from it's mouseOver state - doesn't work
     lastClickedLink = MovieClip(this).name;    //this is supposed to set the new link as the last link clicked after the old one has been released from it's mouseOver state - doesn't work
If anyone can help, that would be great.

What you might be after for that line is to use:
lastClickedLink = MovieClip(event.currentTarget);
For what you show, the name property of an object is a String, so I would expect you to be getting an error regarding trying to get a String to act like a MovieClip when you try to tell it to gotoAndPlay('s2').

Inventory forecast help - dynamically creating formulas?

Post Author: ddenise
CA Forum: Formula
I am writing a report that reconciles sales orders to inventory - essentially, group sales orders by the scheduled production date, list out all the parts that are needed and forecast the impact on inventory, highlighting any areas where inventory is foretasted to go negative. The results right now look like this:                               Part          In Inventory          Needed         Inventory RemainingOrder Number 567     Product Number 311187          Part Number 8111234          100                  5                  95          Part Number 8111235      Product Number 311189          Part Number 8111234          100                 6                  94
          Part Number 8112235 You can see the problem is that once I calculate "Inventory Remaining", the next instance of part 8111234, should have an "In Inventory" value of 95, NOT 100, but 100 is what is stored in the database. The next time that part number is used, the database value is pulled and 100 is displayed. A running total or summary won't work because they cannot be used on 2nd pass formulas/variables; "Inventory Remaining" is a formula evaluated on the 2nd pass.The result that I NEED to come out would be:                                Part          In Inventory          Needed         Inventory Remaining
Order Number 567
     Product Number 311187
          Part Number 8111234          100                  5                  95
          Part Number 8111235
      Product Number 311189
          Part Number 8111234          95                  6                  89
          Part Number 8112235 So.... I am thinking that I need to create a formula that does the following while records are printed:Check to see if a variable whose name is equal to the part number that is being printed (in this case "8111234") and if it doesn't exist, then create it, setting it's value to what is in the database (in this case "100")Use the variable's current value, subtract the quantity of those parts that are needed for the current record being printed and updated the variable's value to this difference.If the variable does already exisit, then use it's current value to display in the "In Inventory" column and,Use the variable's current value, subtract the quantity of those parts
that are needed for the current record being printed and updated the
variable's value to this difference.What this would do is essentially, dynamically create variables that can be used for display and other evaluation and update the particular variable that is related to the part number that is being printed. Has anyone done anything like this before? I'm sure I'm not the first to encounter this situation. Also, if there are other ways to solve this problem that Crystal can handle, please advice - I cannot seem to find any other solution. Regards,

Haha! I got all the formulas down except for the boxes but thank you so much!
I do have a new problem that just arrived, how can I get it to clear itself after I'm finished? So that it acts like a calculator and the columns are automatically cleared and the bars on hand turns into the total bars amount?
It sounds very difficult

Is there a way to use a statically defined appearance stream in a dynamically created annotation?

Hello,
I want to create a document with cascading 'popups'. Not the built-in text-only popup, but an annotation containing an appearance stream that defines text and images. I'm currently using widget annotations based on a pushbutton field.
Each page in my document has many citations that refer to other pages in the document. When a user hovers over the citation, I want a 'popup' to appear containing a depiction of the destination. However, as the destination will itself have citations, I also want the 'popup' to contain citations that the user can hover over, triggering another popup, etc. In this way, a user could navigate throughout the document without leaving the page or even clicking the mouse.
Obviously, with even a modest number of citations per page, pre-calculating and statically defining all of these widgets causes a combinatorial explosion, making the document sluggish and very large.
Instead, I'd like to statically define appearance streams once per document, and then dynamically create annotations and assign the appropriate appearance stream using JS as the user navigates.
So far I've created a named AP in the names dictionary, but I haven't been able to use it to dynamically set an appearance stream of a dynamically created widget annotation.
Also, I've called Doc.getIcon(), passing in the named AP, which returns an Icon object. However, after field.buttonSetIcon() and passing in the named AP, the button does not display the icon.
Is there a way to use a statically defined appearance stream in a dynamically created annotation?
Thank you,
Dave

Hi George, I've gotten named APs to work, and I expect hidden buttons will follow. Thank you very much!
Quick follow-up - I will have many documents embedded within the same pdf file, and some of these documents will contain identical popups. However, I don't want to store identical icons in each document on account of file size.
Instead, I'd like to store one instance of each icon for all documents in the file.
Can I store all of the icons in a single document, and then access them by calling <DocName>.getField().getIcon() from any document in the file?
Thank you again,
Dave

How dynamically create connection pool and Datasource

Hi
How I can dynamically create a connection pool and Data source in Oracle 10g Application server. In our J2EE application the user will be login with db user name, password and database name. I want to create connection pool and data source on the fly while login the user with database name. I our application we have access approximate 80 Databases. so my approach is given bellow
1) Planning to create 80 connection pools and 80 Data sources so when user logs in while selecting the db name i will call the appropriate data source and create the DB connection. Is there any limitation to create number of data sources in oracle app server?
2) Create DB connection with out using connection pool and data source. But i am not prefer this approach coz we need to handle some transaction in our application.
Kindly throw some light on managing connection pool programmatically or in application run time.
I would really appreciate if any one can provide any links or any inormation on this issue.
Thanks in advance.

Kindly let me know is there any drawbacks to create 80 Data Sources to connect 80 database in Oracle 10G App server and each data sources should have one connection pool. so i need to create 80 connection pool. Please let me know is this right approach or any work around to create Data source on fly for each request for corresponding database.

Assigning a 'dynamically created sequence' value to a variable

in my procedure i am creating a sequence on the fly, i am preparing the name with some passed parameters like below
v_seq_name := 'seq_'||loadid||v_table_name;
execute immediate 'CREATE SEQUENCE '||v_seq_name||' MINVALUE 1 MAXVALUE 999999999999999999999999999 START WITH 1 increment by 1 cache 20';
and now after doing some operations i need to assign the current value of sequence to a number variable i tried following but not working
1) v_curr_value : = v_seq_name.currval ;
2) select v_seq_name||'.nextval' into v_curr_value from dual;
can you please suggest me how i can get the value in plsql block.

Having said that, your architecture is probably wrong if you are dynamically creating things in a procedure.
Why do you need to create them dynamically?

Dynamically creating a Record Group based on Previously entered Record Grou

Forms [32 Bit] Version 10.1.2.3.0 (Production)
Hi,
I know how to dynamically create a record group based on a query and putting the code in When new form instance.
My query is. I have a form which has multiple Record Groups and the user wants to dynamically create subsequent groups based on previous groups.
For example
I have a record group with selects a Location,
when the user selects the Location from a list of values
the 2nd record group called 'Cost Centres' will have to filter out only those with the locations selected above.
How can I populate the 2nd record group at run-time when I do not know what site the user will select?
If I simply populate in when new form instance as in location and just select everything, the list of values populates.
CC field is a LIST ITEM and the list style is a POP LIST, it is not required.
I have put the code in the Location field in the when-list-changed trigger.
I am getting this error:
frm-41337: cannot populate the list from the record group
here is the code:
DECLARE
v_recsql Varchar2(1000); -- The SQL for creating the Record Group.
v_recgrp RecordGroup; -- Record Group
v_status Number; -- Return Value of Populate_Group function.
c_where VARCHAR2(1000);
BEGIN
     IF :location = '1' THEN
          c_where := ' substr(cost_centre,1,2) in (''01'',''02'')';
     ELSIF :location = '2' THEN
          c_where := ' substr(cost_centre,1,2) in (''02'',''03'')';
     ELSIF :location   = '3' THEN
          c_where := ' substr(cost_centre,1,2) in (''01'',''11'',''07'')';
               ELSE
          c_where := ' 1=1'; --EVERYTHING
     END IF;
v_recsql := 'SELECT cost_centre, description FROM   cost_centres where '||c_where;
-- Create the Record Group
v_recgrp := CREATE_GROUP_FROM_QUERY('v_recgrp', v_recsql);
IF NOT ID_NULL(v_recgrp)
THEN -- No Error, record group has been successfully created.
-- Populate Record Group
v_status := POPULATE_GROUP('v_recgrp');
IF v_status = 0
THEN -- No Error. Record Group has been Populated.
POPULATE_LIST('block.CC', 'v_recgrp');
END IF; -- IF v_status = 0
-- Delete the Record Group as it is no longer needed.
DELETE_GROUP('v_recgrp');
END IF; -- IF NOT ID_NULL(v_recgrp)
END;thanks for your assistance.

Hi,
Once record status gets change for block you can not populate/repopulate the list item. Keep those list items as non-database item with different names and create different items as database orignal items. Than assign the values in WHEN-LIST-CHANGE trigger to the actual database items.

Uploading data from excel file to a dynamically created internal table

Hi,
I have a requirement where i have to upload data from an excel file into a database table. I would be able to determine the structure of the table only at runtime based on the user input.. so i have created an internal table dynamically.
Could you please tell me if its possible to upload data from an excel file to the dynamically created internal table using any function modules?
I thought of doing this by declaring a generic internal table of one field and then uploading the *.csv file into it and then splitting it based on "," and then assigning it to the field symbol referencing the internal table.. but my file length exceeds 132 characters and i'm only able to get data of lenght 132 char's in my internal table ( generic one).
Could anyone please show me a way around this.

Dynamically create and remove TEXT items in forms

Hi Guys,
Is there a way to dynamically create and remove TEXT items in form. For example I have the EMP and DEPT table and when
I select the EMP table name from the LOV, rows of the EMP table with column name and data should get displayed on the screen and likewise a similar action for DEPT table and
so on. I have about 90 tables from where data could be required to view and edit. They all have varying number of columns.
Any suggestions ?
Thanks

Passing values to dynamically created internal table

Hi,
I have the flat file data as
f1,f2,f3........so on
where f1 f2 and f3 are field names.
I have a variable var which contains the data
V1,0001,0002.........so on
data: var type string.
The value of field f1 is v1
The value of field f2 is 0001
The value of field f3 is 0002.......so on
FIELD-SYMBOLS:     <fs_1> TYPE STANDARD TABLE
I have dynamically created an internal table for fields f1 f2 f3 ...... using
CALL METHOD cl_alv_table_create=>create_dynamic_table
    EXPORTING
      it_fieldcatalog           = lt_fieldcatalog
    IMPORTING
      ep_table                  = <fs_data>
    EXCEPTIONS
      generate_subpool_dir_full = 1
      OTHERS                    = 2.
IF sy-subrc <> 0.
ENDIF.
ASSIGN <fs_data>->* TO <fs_1>.
Now for <fs_1> I have to pass the corresponding values of the fields f1 f2 f3 .
How can i solve this.
Thanks and regards ,
Parvatha Reddy

Hi,
There is no data in <fs_1>.
I need to pass the data form the string var to the fields of <fs_1>..
I understand that you want to populate the internal table <fs_1>.
for that you fist need work area.. use below statement to create work area..
DATA: new_line TYPE REF TO data.
CREATE DATA new_line LIKE LINE OF <fs_1>.
ASSIGN new_line->* TO <fs_2>.
<fs_2> is not your work aread...
to assign value to each field of you work aread <fs_2>. use statement
ASSIGN COMPONENT 1 OF STRUCTURE <fs_2> TO <fs_3>.
<fs_3> = f1 .
now <fs_3> will point to the first field of work area <fs_2>, f1 is value from your string .. repeat above for each field in workarea, by increasing the component number. Once your work area is filled
append it to table.
append <fs_2> to <fs_1>
apologies if I am not getting the requiremnt correctly..

How to synch values of fields (cbo & text) in Master Pages section in dynamically created pages?

HI folks,
I have a requirement for a form that has a common master page with a checkbox and text field in it.   The document is basically a table that dynamically adds rows as the user adds entries.   When the first page is full, a second page is dynamically created and the Master page format (including the checkbox & text field) applied to it.
When the user sets the checkbox on one page and/or adds text, all of the checkboxes on all of the dynamically created pages (in the master section) and all of the text boxes need to change to show the same values.
However, I can't figure out how to address the fields on the other pages.   The number of pages changes from user to user, so I can't address them with a static reference.
Does anyone know how to keep these fields in synch?
Thanks in advance!

It woudl be easier to show than to explain it ...can you share the file? You can send it to [email protected] Include a description of the issue with your email please.

How to generate report with dynamic variable number of columns?

How to generate report with dynamic variable number of columns?
I need to generate a report with varying column names (state names) as follows:
SELECT AK, AL, AR,... FROM States ;
I get these column names from the result of another query.
In order to clarify my question, Please consider following table:
CREATE TABLE TIME_PERIODS (
PERIOD     VARCHAR2 (50) PRIMARY KEY
CREATE TABLE STATE_INCOME (
     NAME     VARCHAR2 (2),
     PERIOD     VARCHAR2 (50)     REFERENCES TIME_PERIODS (PERIOD) ,
     INCOME     NUMBER (12, 2)
I like to generate a report as follows:
AK CA DE FL ...
PERIOD1 1222.23 2423.20 232.33 345.21
PERIOD2
PERIOD3
Total 433242.23 56744.34 8872.21 2324.23 ...
The TIME_PERIODS.Period and State.Name could change dynamically.
So I can't specify the state name in Select query like
SELECT AK, AL, AR,... FROM
What is the best way to generate this report?
