Here is sample code
<script type="text/javascript">

<td onclick="callForm('Data3')" > Data3 </td>
<td onclick="callForm('Data4')" > Data4 </td>
</tr>

Trying to get multiple cell values within a geometry

I am provided with 3 tables:
1 - The GeoRaster
2 - The geoRasterData table
3 - A VAT table who's PK is the cell value from the above tables
Currently the user can select a point in our application and by using the getCellValue we get the cell value which is the PK on the 3rd table and this gives us the details to return to the user.
We now want to give the worst scenario within a given geometry or distance. So if I get back all the cell values within a given geometry/distance I can then call my other functions against the 3rd table to get the worst scores.
I had a conversation open for this before where JeffreyXie had some brilliant input, but it got archived while I was waiting on Oracle to resolve a bug (about 7 months)
See:
Trying to get multiple cell values within a geometry
If I am looking to get a list of cell values that interact with my geometry/distance and then loop through them, is there a better way?
BTW, if anybody wants to play with this functionality, it only seems to work in 11.2.0.4.
Below is the code I was using last, I think it is trying to get the cell values but the numbers coming back are not correct, I think I am converting the binary to integer wrong.
Any ideas?

Hey guys,
Zzhang,
That's a good spot and as it happens I spotted that and that is why I am sure I am querying that lob wrong. I always get the a logic going past the total length of the lob.
I think I am ok using 11.2.0.4, if I can get this working it is really important to us, so saying to roll up to 11.2.0.4 for this would be no problem.
The error in 11.2.0.3 was an internal error: [kghstack_underflow_internal_3].
Something that I think I need to find out more about, but am struggling to get more information on is, I am assuming that the lob that is returned is all cell values or at lest an array of 4 byte (32 bit) chunks, although, I don't know this.
Is that a correct assumption or is there more to it?
Have either of you seen any documentation on how to query this lob?
Thanks

How can i fetch records from 3 tables in a single query without using join

Hi.
Can any body please tell me <b>How can i fetch records from 3 tables with a single query without using joins</b>
Thanx
prabhudutta

Hi Prabgudutta,
We can fetch the data by using the views concept.
Go throuth this info we can know the how to create view and same like database table only we can fetch the data.
Views conatin the data at runtime only.
Four different view types are supported. These differ in the
way in which the view is implemented and in the methods
permitted for accessing the view data.
Database views are implemented with an equivalent view on
the database.
Projection views are used to hide fields of a table (only
projection).
Help views can be used as selection method in search helps.
Maintenance views permit you to maintain the data
distributed
on several tables for one application object at one time.
step by step creation of Maintenance view:
With the help of the table maintenance generator, you are able to maintain the ENTRIES of the table in SM30 transaction.
It can be set in transaction SE11 - Tools - Table maintenance generator.
Table maintanance Generator is used to manually input values using transaction sm30
follow below steps
1) go to se11 check table maintanance check box under attributes tab
2) utilities-table maintanance Generator-> create function group and assign it under
function group input box. Also assign authorization group default &NC& .
3) select standard recording routine radio in table table mainitainence generator to move table
contents to quality and production by assigning it to request.
4) select maintaience type as single step.
5) maintainence screen as system generated numbers this dialog box appears when you click on create button
6) save and activate table
One step, two step in Table Maintenance Generator
Single step: Only overview screen is created i.e. the Table Maintenance Program will have only one screen where you can add, delete or edit records.
Two step: Two screens namely the overview screen and Single screen are created. The user can see the key fields in the first screen and can further go on to edit further details.
SM30 is used for table maintenance(addition or deletion of records),
For all the tables in SE11 for which Table maintenance is selected , they can be maintained in SM30
Sm30 is used to maintain the table ,i.e to delete ,insert or modify the field values and all..
It creates the maintenance screen for u for the aprticular table as the maintenance is not allowed for the table..
In the SE11 delivery and maintenance tab, keep the maintenance allowed..
Then come to the SM30 and then enter the table name and press maintain..,
Give the authorization group if necessary and give the function group and then select maintenance type as one step and give the screen numbers as system specified..
Then create,,,
Then u will able to see the maintenance view for the table in which u can able to insert and delete the table values...
We use SM30 transaction for entering values into any DB table.
First we create a table in SE11 and create the table maintenance generator for that Table using (utilities-> table maintenance generator) and create it.
Then it will create a View.
After that from SM30, enter the table name and Maintain, create new entries, change the existing entries for that table.
Hope this resolves your query.
Reward all the helpful answers.

How to get TableView cell values

Hi All,
I'm new to PDK.
I have a TableView which set to Single Selection (the table has a column of radio buttons).
When the user selects a row I want to get the cells' values of the row from the client side.
I can get the row's number by using the following code:
tvModel.setOnClientRowSelection("generateNumber(htmlbevent)");
function generateNumber(myEvent) {
alert(myEvent.obj.clickedRow.toString());
Is there a function like getValueAt(row,col)?
How can I solve this?
Thanks,
Omri

Hi
There is a function getValueAt(row,col) to get a value at particular row and column.
Please go through the followin forum thread which is related to your problem:

I downloaded and paid for an app on my ipad, how can I get it free on my iphone without using itunes as my laytop is broken. I cannot seem to find the purchase tab in app store? I am logged in using the same ID

I downloaded and paid for an app on my ipad, how can I get it free on my iphone without using itunes as my laytop is broken. I cannot seem to find the purchase tab in app store? I am logged in using the same ID

First, the app must be universal...designed for both iPhone/iPad:
Tap App Store.
Make sure you're signed in with the same Apple ID used for the original purchase.
Tap Updates.
Tap Purchased on the resulting screen.
Locate the app in your Purchased tab.
Tap the download icon.
The app will begin downloading and you'll be taken back to your home screen.

Does anyone know how to get an application you had once without using App Store?

Does anyone know how to get an application you had once without using App Store?
Because I'm underage and I couldn't get it back.
I just want it back, I'm not going to use any money in App Store...

When you say you "had it once", how did you get it then? The App Store has only been around for a few years, so there are lots of apps out there that you would once get from the developer, but now they're only available on the App store. Which app(s) are you referring to?

How to get the Row and Column values in ALV (without using Objects)

Hi All,
I need to get the Row / Column when double click is used in ALV, I can use the double click event for this. However, I do not want to use the Object Oriented ALV. I want to implement the same functionality using general (using functions) ALV.
Is there any way to get the row / column values for a Generia (non-OOPs) ALV report.
Please help.
Thanks,
Vishal.

Hello,
The only think you have to do is to get the index where the user clicked, and then read the internal table you sent to the alv
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
    EXPORTING
      i_callback_program       = 'prg_name'
      i_callback_pf_status_set = 'SET_PF_STATUS'
      i_callback_user_command = 'USER_COMMAND' " this is to the click event!!
      i_callback_top_of_page   = 'TOP_OF_PAGE'
      is_layout                = alv_layout
      it_fieldcat              = alv_fieldcat
      i_save                   = 'A'
      it_events                = alv_events[]
    TABLES
      t_outtab                 = i_totmez. ---> TOUR IT.
IF sy-subrc <> 0.
    MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
          WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
ENDIF.
" then....
FORM user_commandUSING r_ucomm     TYPE sy-ucomm
                                ls_selfield TYPE slis_selfield.
" r_ucomm -> HAS THE STATUS
" ls_selfield-tabindex -> HAS THE SELECTED INDEX
" THEN READ THE INTERNAL TABLE
" HERE YOU WILL HAVE THE SELECTED ROW
READ TABLE i_totmez INDEX ls_selfield-tabindex.

Get the message attribute values in Orchestration without using property promotion

I have the following schema :
Now I want to get the values of FName,LName in orchestration without using any property promotion ?
Prakash

There are also multiple ways of creating the Xpath:
- Full path with namespaces - Rahul Madaan showed this one
- Full path without namespaces:
FName = xpath(InputMessage, "string(/*[local-name()='Root']/*[local-name()='IntField'])");
I think this method is handy if you have multiple schemas with similar structure but the namespace
changes. This is also easier to read and less prone to errors if there are any changes.
If you for example wanted the node #3, then it would be
FName = xpath(InputMessage, "string(/*[local-name()='Root']/*[local-name()='IntField'][3]/*[local-name()='IntSubField'])");
- Jump directly to the field/node you need (this one works for at least xml elements):
xpath(InputMessage, "string(//*[local-name()='IntField'])");
I find this useful when picking up key-values from the message, that can be available only once.
All the examples above are for elements. Since you are picking up value from an attribute, the actual structure
is
varFName = xpath(InputMessage,"string(/*[local-name()='StudentDetails']/*[local-name()='Student']/@*[local-name()='FName'])");
And to learn the rest of the possibilities of Xpath, like count, different types, more detailed selections
of the correct Node (Like example, I want only the one where FNAME = 'MyFName') You can try something like: http://social.technet.microsoft.com/wiki/contents/articles/6944.biztalk-orchestrations-xpath-survival-guide.aspx
Also get DanSharp XmlViewer. It will help you quite a bit when fine tuning the xpaths.

Change background color of a table based on table cell values quickly.

Is there a more effecient way to change the background color of a table based on the cell values of the table?
I can do this cell-by-cell using the property node, but it is very slow. It helps a little by deferring panel update, but it is still slow. Is there a better way?
Thanks.
Ian

If you want to color each cell according to the value, you need to do it one cell at a time and the above answers don't apply.
You can dramatically speed up things by defering front panel updates for the duration of the operation.
(sample code can be seen in the top picture here)
EDIT: I noticed you tried this already. Can you show us your code?
How many cells need to be colored on average? If there are not that many, first write the background color using -2,-2, the only write the few cells to be colored, skipping the rest.
How big is the table? If it is much bigger than the table indicator, all you need is to color the visible parts whenever the data or the scroll position changes.

To get the button on system form without using ADDON

Hello,
I want to get the new button on tne System Form without creating or using Add-on.
And while clicking on that button, i want to display "Hello World" message..
Can u please tell me how to get new button on the System form without using AddOn?
Thanks
Nisha

Hi Nisha,
It is not possible to add a button on a system form without using an add-on, this is because in order to add a button an a system form you have to access its form id at run time (that converts this standard form into a customized form for your add-on ) the location of some existing control that will be taken as the base location identifier for the new control and only then you would be able to add a new button on the form.

How to get selected Cell value in datagrid?

Hi guys, I have a datagrid that is editable. I was wondering if it's possible to retreive the cell value after user edits the single cell.
My datagrid will trigger griditemEditorSessionSave event if users finish the editing, but I don't know how to get the new cell value.
//script
protected function dg_gridItemEditorSessionSaveHandler(event:GridItemEditorEvent):void
     //I can only get the columnIndex but not the value
      Alert.show (event.columnIndex);
//mxml
<s:DataGrid id="dg" editable="true" x="5" y="3" width="734" height="153"
                  gridItemEditorSessionSave="dg_gridItemEditorSessionSaveHandler(event)"

How to transfer the attributes of one page to other without using submit

hi friends,
I have faced a prob when i use submit to transfer the parameter from page1 to page 2 i can get the parmeter in page 2. But when u try to implement through action of onclick i cannt able to fetch the value of the parameter in the jsp page2. is there is any other option equivalent to request.getParmeterValues. in setting the attribute.
can any one give me the solution to overcome this prob it will be appreciated and thanked by me.

Hi Anand,
We can send request to server with submitting the page.
why dont you try using xml over http.
This is some thing like thru java script you can pass the values to some Servlet, construt the object there, while returning from the servlet just put your response thru printwriter pw object like pw.print(response);
In java script you can mensioned to retrieve the servlet result.
check the following code, it would help you
EXPLORER_xmlHttp = new ActiveXObject("Microsoft.xmlHttp");
serverURL = "someUrl.com"+ "method=" + "callMethod.do";
EXPLORER_xmlHttp.open("POST",serverURL,true);
EXPLORER_xmlHttp.setRequestHeader("ClientType","HTML");
EXPLORER_xmlHttp.onreadystatechange = Return_Method_onready;
(control will come from servlet to the above method)
set the other headers what ever you want...
then set the input parameters
EXPLORER_xmlHttp.send(inputAttr);
from Servlet you get the response directly to the javaScript method which you specified.
this is how it works.
Regards
