Dynamically creating a CR by code

Post Author: ffderennes
CA Forum: .NET
Hello, I am discovering crystal reports (I have the basic version included with VS 2005). I would like to dynamically create a report by the code.I need to generate a report from a Dataset or DataTable but this source is variable.The columns of the table are not always the sames. I did research, and all the tutorials I have seen create models primarily via visual studio (with known column names). I wonder if it is possible to create and edit from A to Z the report by the code. I tried (creation of the object ReportDocument, but I can not add a section, TextObject ...). Visual Studio back me errors and tells me that these objects have no constructor. I began to wonder if it was possible to do that.If yes, in which version (maybe mine is too old). In any case, if someone has a runway, an example or a tutorial to advise me, I am taker. thank you in advance.

You can use the Report Application Server (RAS) engine to dynamically create reports, or add items to existing reports. RAS is not included with the verison of Crystal Reports that comes with .NET. Full versions such as XI R2 do include RAS.
Some samples can be found on the support site.

Dynamically creating a AS3.0 code based on animations made at runtime

Hello everyone,
I am new to AS3.0 and always getting tasks that is very very challenging. Here is the challenge.
Need to create a flash application where the user can create animations using images(upload) and text dynamically and export to a swf file. This was my previous post and the answers from the forum members was "impossible - 95%" and "Possible - 5%" (my average calcu).
http://forums.adobe.com/thread/678202?tstart=0
Now i got an idea from the "Possible - 5%". That is
as per the discussion in the above link there are compliers that can create swf files from the command prompt using haxe, swfmill, neko etc etc. these requires a AS3.0 class file to get the output.
now my question is can we generate the AS3.0 code from the swf file where the animations using images, text are done on the runtime stage. after the user is done with his animations he can click publish btn were we need to create the AS3.0 code and send to the command promt for getting the swf file as output.
i think this task is quite hard. but any help regarding this will let me in a right direction.
thanks in adv for any helps

Assuming that WYSIWYG concept is valid, you are better off with Flex. Flex offers xml structure that you can use as template and just write values. Then this XML can be used by compiler as it is used in Flex.
In any case, this is a very tedious and advanced task you are embarking on. If you are talking about couple of objects and simple animations - it is not that bad. But if there is more - it is difficult mainly because of the multitude of use cases and exponential growth in objects relationships from both display list and user interaction standpoint.
I was a part of such project about 2 years ago and I see that one has to be an excellent UX engineer, very good architect and an advanced AS developer in order to make this kind of application worth pursuing.

Dynamic created alv adding each tax code in bottom of column.

Hi expert,
i created dynamic alv using dynamic internal table and want to add each column value in bottom of each column
example :1
                2
                3
     total
this is not simple alv report it's dynamic alv.
pls give me code.

In your dynamic internal tables, does all fields can be summed?
If yes, I would do like this. Create a generic a variable say V_FIELD. Assume maximum program may have 30 fields.
data v_field type char30
data v_num type char2.
data v_field1 type char30.
data v_field30 type char30.
do.
add 1 to v_num.
CONCATENATE 'V_FIELD' v_num into v_field.
assign (v_field) to <fld>."This holds the value of the field. Initially 0.
ASSIGN COMPONENT sy-index OF STRUCTURE <YOUR_DYNAMIC_STURCT> TO <fld_value>.
if sy-subrc = 0.
<fld> = <fld> + <fld_value>.
else.
exit.
endif.
enddo.
As the DO loop process it sums up for each column total into each variable. Once complete data is processed through, add these variable to as new record to internal table.
If all fields are not summed type of field then validate by the on the field type and process the logic

Problem with embeding the same view in dynamically created view container

Hello Experts,
              I am getiing a dump when i try to embed the same view inside the dynamically created view container of
dynamically created tabs of a tabstrip
The requirement go like this, i have 2 views in which i have have to embed the 2nd view to view1 where i have an empty
tabstrip without tabs. During runtime i create tabs as well as view containers accordingly and then try to embed view2 in tabs.
I have put the below mentioned code in HANDLEIN,
DATA: lref_vcntlr TYPE REF TO if_wd_view_controller,
        lref_comp    TYPE REF TO if_wd_component_usage,
        lv_embed_pos TYPE string.
lref_vcntlr = wd_this->wd_get_api( ).
lv_embed_pos = 'FILE_PERS_EDIT/VC_GENERAL'.
TRY.
      CALL METHOD lref_vcntlr->do_dynamic_navigation
        EXPORTING
          source_window_name        = 'FILE_PERSISTENCE_WND'          " Window
          source_vusage_name        = 'FILE_PERS_EDIT_USAGE_1'       " Source View usage
          source_plug_name          = 'TO_EDIT_LAYOUT'                       " Outbound plug
          target_view_name          = 'PERS_EDIT_LAYOUT'                  " Second view to be embedded
          target_plug_name          = 'IN'                                                  " Second view inboun plug
          target_embedding_position = lv_embed_pos
        RECEIVING
          component_usage           = lref_comp.
    CATCH cx_wd_runtime_repository .
ENDTRY.
wd_this->fire_to_edit_layout_plg( ).
This works fine for the first time.
However onaction tab select i change the embeding position( 'FILE_PERS_EDIT/view container name of different tab') of the view2 an try to embed view2 in a different tab.
At this point i get a dump stating View2 already present in the window 'FILE_PERSISTENCE_WND' of component.
I think, the view2 embediing has to be removed before i add the view2 in a different tab
Kindly let me know how to remove view2 embedding from tab1 before i add a view2 to a different tab or is there any other
means to handle this problem?
Thanks & Best Regards,
Srini.

Hello Srini,
I found a solution to your problem, because I had a similar task.
In WDDOINIT I changed the method do_dynamic_navigation to if_wd_navigation_services_new~prepare_dynamic_navigation:

l_view_controller_api = wd_this->wd_get_api( ).

Dynamically creating oracle table with csv file as source

Hi,
We have a requirment..TO create a dynamic external table.. Whenever the data or number of columns change in the CSV file the table should be replaced with current data and current number of columns...as we are naive experienced people in oracle please give us a clear solution.. We have tried with a code already ..But getting some errors. Code given below..
thank you
we have executed this code by changing the schema name and table name ..Remaining everything same ...
Assume the following:
- Oracle User and Schema name is ALLEXPERTS
- Database name is EXPERTS
- The directory object is file_dir
- CSV file directory is /export/home/log
- The csv file name is ALLEXPERTS_CSV.log
- The table name is all_experts_tbl
1. Create a directory object in Oracle. The directory will point to the directory where the file located.
conn sys/{password}@EXPERTS as sysdba;
CREATE OR REPLACE DIRECTORY file_dir AS '/export/home/log';
2. Grant the directory privilege to the user
GRANT READ ON DIRECTORY file_dir TO ALLEXPERTS;
3. Create the table
Connect as ALLEXPERTS user
create table ALLEXPERTS.all_experts_tbl
(txt_line varchar2(512))
organization external
(type ORACLE_LOADER
default directory file_dir
access parameters (records delimited by newline
fields
(txt_line char(512)))
location ('ALLEXPERTS_CSV.log')
This will create a table that links the data to a file. Now you can treat this file as a regular table where you can use SELECT statement to retrieve the data.
PL/SQL to create the data (PSEUDO code)
CREATE OR REPLACE PROCEDURE new_proc IS
-- Setup the cursor
CURSOR c_main IS SELECT *
FROM allexperts.all_experts_tbl;
CURSOR c_first_row IS ALLEXPERTS_CSV.logSELECT *
FROM allexperts.all_experts_tbl
WHERE ROWNUM = 1;
-- Declare Variable
l_delimiter_count NUMBER;
l_temp_counter NUMBER:=1;
l_current_row VARCHAR2(100);
l_create_statements VARCHAR2(1000);
BEGIN
-- Get the first row
-- Open the c_first_row and fetch the data into l_current_row
-- Count the number of delimiter l_current_row and set the l_delimiter_count
OPEN c_first_row;
FETCH c_first_row INTO l_current_row;
CLOSE c_first_row;
l_delimiter_count := number of delimiter in l_current_row;
-- Create the table with the right number of columns
l_create_statements := 'CREATE TABLE csv_table ( ';
WHILE l_temp_counter <= l_delimiter_count
LOOP
l_create_statement := l_create_statement || 'COL' || l_temp_counter || ' VARCHAR2(100)'
l_temp_counter := l_temp_counter + 1;
IF l_temp_counter <=l_delimiter_count THEN
l_create_statement := l_create_statement || ',';
END IF;
END;
l_create_statement := l_create_statement || ')';
EXECUTE IMMEDIATE l_create_statement;
-- Open the c_main to parse all the rows and insert into the table
WHILE rec IN c_main
LOOP
-- Loop thru all the records and parse them
-- Insert the data into the table created above
END LOOP;

The initial table is showing errors and the procedure is created with compilation errors
After executing the create table i am getting the following errors

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.

How to set a value to a dynamically created node/attribute?

Hi,
I dynamically created attributes using the following method,
IWDNodeInfo cbOptions = wdContext.getNodeInfo().addChild("cbOpt"+count, null, true, true, false, false, false, true, null, null, null);
cbOptions.addAttribute("opt"+critEle.getQuest_Critid(), "ddic:com.sap.dictionary.string");
How do i assign a value to it now, since the node/attribute cannot be accessed via wdcontext?
On a side note, it seems really troublesome if i need to use a checkbox grp(s) dynamically. I actually need to dynamically create a seperate node + attribute for each checkbox grp i have. Is there any better way to do this?
Thanx in advance

Hi
Steps:
1) Create the action click is done statically (you cannot create action dyanmically)
2) binding the action click to checkbox dynamically
code
public static void wdDoModifyView(IPrivateDynamicProgrammingView wdThis, IPrivateDynamicProgrammingView.IContextNode wdContext, com.sap.tc.webdynpro.progmodel.api.IWDView view, boolean firstTime)
    //@@begin wdDoModifyView
     if(firstTime){
                  IWDTransparentContainer con=(IWDTransparentContainer)view.getElement("RootUIElementContainer");
          IWDCheckBox checkBox=(IWDCheckBox)view.createElement(IWDCheckBox.class,"ck");
          IWDAction act=wdThis.wdCreateAction(IPrivateDynamicProgrammingView.WDActionEventHandler.CLICK,"");
          checkBox.setOnToggle(act);
          con.addChild(checkBox);
    //@@end

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').

Not Yet Documented ADF Ex 9 Dynamically Binding to Dynamically Created View

I have dynamically created a View Object and would like to build a dynamic HTML Table on a web page based upon my view. I think something similar is done in Steve Muench's sample #9. My problem is I am new to ADF and the example was done in an earlier version of JDev (I am using 10.1.3.0.4) and the JSP page in the example will not compile. I get an error at:
<textarea style="width: 100%" name="sql" rows="3" ><c:out value="${param.sql}"/></textarea><br>
Saying required param "cols" is missing. I also get a nesting error in this code:
<tr>
<c:forEach var="attributeLabel" items="${bindings.DynamicViewObject.labelSet}">
<th>
because (I think) the compiler expects a </tr> and it is seeing the <c:forEach var="attributeLabel"> tag.
Is there a setting in JDeveloper I can use to allow this application to compile? Is there a similar example done in JSF as that is what my current application is being developed using.
TIA,
Jeff

Any help on this? Kind of Urgent...

Adding f:Attribute dynamically to a dynamically created Button

Hi ,
I am trying to dynamically create a CommandButton and attach a f:Attribute to the same. But somehow I am not able to get hold of the correct API to do the same -
>RichCommandButton button=new RichCommandButton();
>button.setText("Ok");
>AttributeTag attr=new AttributeTag();
>attr.setValue("DC_OPERATION_BINDING", "bindings.DENY");
>button.getChildren().add(attr);
The issue is that the add method expects a UIComponent and attr is of type com.sun.faces.taglib.jsf_core.AttributeTag

gues u can use it like
button.getAttributes().put(DC_OPERATION_BINDING", "bindings.DENY");
{code}

How to set the cardinality property as 1..n for a dynamically created node

Hi...everybody
    I am creating Dropdown by index UI element and the
context atrributes dynamically.To bind multiple data to a dropdown
the cardinality property of the node should be 0..n or 1..n,
But i could not set the property of the dynamically created context node to 0..n ...
can any body suggest me..
I implemented the following code in WDDoModify View
IWDTransparentContainer tc=(IWDTransparentContainer)view.getElement("RootUIElementContainer");
IWDNodeInfo node = wdContext.getNodeInfo().addChild("DynamicNode",null,true,true,false,false,false,true,null,
          null,null);
IWDAttributeInfo strinfo=node.addAttribute("Value","ddic:com.sap.dictionary.string");
dbyindex.bindTexts(strinfo);
tc.addChild(dbyindex);
I could successfully display one value in the drop down,by adding the following code before the line tc.addchild(dbyindex);
IWDNode node1=wdContext.getChildNode("DynamicNode",0);
IWDNodeElement nodeElement=node1.createElement();
nodeElement.setAttributeValue("Value","Hello");
node1.addElement(nodeElement);
but when
i am trying to bind multiple values i am getting Exception ,,,,

hi
you are getting the exception because of cardinality property.
i.e   true,false and
you are trying to add morethan one element.
so,if you want to add morethan one than one element you have to set the cardinality property to true,true (or) false,true.
In your code do the following modification for changing the cardinality.
For 0..n -->false,true
      1..n-->true,true
IWDTransparentContainer tc=(IWDTransparentContainer)view.getElement("RootUIElementContainer");
IWDNodeInfo node = wdContext.getNodeInfo().addChild("DynamicNode",null,true,true,false,false,false,true,null,
null,null);
IWDAttributeInfo strinfo=node.addAttribute("Value","ddic:com.sap.dictionary.string");
dbyindex.bindTexts(strinfo);
tc.addChild(dbyindex);
hope this will solve your problem.
In addchild(..) the parameters are
addChild("Name ,
                Element class for model node ,
                Is singleton? ,
                Cardinality ,
                Selection cardinality ,
                Initialise lead selection? ,
                Datatype ,
                Supplier function ,
                 Disposer function);

How to get a dynamically created symbol to delete itself on click?

Here's the setup...
I want to have a dynamically created symbol appear upon click of a hotspot. In this case, you click on a pulsating hotspot and a popup box appears.
Here's the code I'm using for that.
//Create an instance element of a symbol as a child of the given parent element
var mySymbolObject = sym.createChildSymbol("gardern_toxins_popup","stage");
So we have the symbol "garden_toxins_popup" from my library placed dynamically on the page. I would like to assign an action to the pop-up itself that allows you to remove the symbol from the stage upon click.
I feel silly for not being able to figure this out. I tried iterations of this bit of code...
//Get the stage from the composition level, get the symbol
sym.getComposition().getStage().getSymbol("garden_toxins_popup").delete();
...but it doesn't work.
So I tried thinking like I was back in Flash and tried the following...
this.parent.removeChild(this);
But no joy on that as well. Is there something I haven't addressed in this logic or am I going about it in the wrong way? Thanks!

Hi, chirpieguy-
You'll want to use the deleteSymbol() API.
http://www.adobe.com/devnet-docs/edgeanimate/api/current/index.html
BTW, you should use the capitalized "Stage" to add it to the Stage - the lower case stage has a special meaning with Animate and might not give you what you want..
sym.createChildSymbol("gardentoxins", "Stage");
In the symbol itself, create a click event on a container div, then:
sym.deleteSymbol();
That being said, you don't need to dynamically create and delete an object. What you can do is to use hide() and show() on an element and use the coordinates of your click to change the CSS value of top/left of this object so that you don't have to do the object management I highlighted above.
Hope that points you in the right direction.

Dynamically creating variable names in javascript

Hi.
I have to create variable names dynamically in JavaScript.
My JSP file accesses information from Database and forms a String corresponding to the information received.
This String is passed to a JAvaScript function that should CREATE a variable with that NAME.
For Ex:
My database access resulted in a single row...
id name sal
34 John Smith 38000
the resulting VARIABLE NAME should be Menu34. 34 comes from the database result.
Is there any function to dynamically create a variable name in JavaScript?
Thanks in advance.

The JSP is printing the contents of an HTML page, and Javascript code can be part of that output...
So you would just write out the stuff, something like this....
<script>
<% while(rs.hasNext()) { %>
var Menu<%= rs.getInt("id") %> = '<%= rs.getString("name") %>';
<% } %>
</script>
In the browser, it'll just look like another long list of Javascript variables.

Adding AJAX support for dynamically created panelGrid components

Hi everyone!
I would like to ask help from anyone who may have encountered similar problem before...
I have a panelGrid whose component is dynamically created by the backing bean. Here is my JSF code:
<h:panelGrid styleClass="panelGrid"
          rowClasses="tsPanelGridRowClass" columns="8" cellpadding="0"
          cellspacing="2" bgcolor="transparent" style="margin-left: 10px"
          id="revCenterItemPanelGrid"
          binding="#{pc_Touchscreen_pull_select_item.revCenterItemPanelGrid}">
</h:panelGrid>And here is the code for backing bean that adds content inside the panelGrid:
HtmlOutputText index = (HtmlOutputText) app.createComponent(HtmlOutputText.COMPONENT_TYPE);
index.setId("1");
index.setValue(String.valueOf(1));
index.setStyle("datagridtext");
revCenterItemPanelGrid.getChildren().add(index);On click of a button...
<a4j:commandButton value="Update"
          styleClass="commandExButtonPou2" id="button1" reRender="revCenterItemPanelGrid"
          actionListener="#{pc_Touchscreen_pull_select_item.doSortActionListener2}">
          <f:attribute name="order" value="2"></f:attribute>
          <f:attribute name="toggleState" value="off"></f:attribute>
</a4j:commandButton>the backing bean is supposed to update the value of the outputText
doSortActionListener2() {
HtmlOutputText index = (HtmlOutputText) app.createComponent(HtmlOutputText.COMPONENT_TYPE);
index.setId("2");
index.setValue(String.valueOf(2));
index.setStyle("datagridtext");
revCenterItemPanelGrid.getChildren().add(index);
}However, update doesn't seem to work. I have been successful in adding ajax support to a panelGrid that is not dynamically created but not for this one.
Has anyone encountered this error before? Any ideas?
Thanks in advance!
