Hierarchical tree and interacting with data block

I have a hierarchical tree that is used to pick records that are shown in another data block. I have a list item in the data block that changes the arrangement of nodes in the hierarchy. My problem is that after the update, I select the node, but the wrong data shows up in the other data block (eg. node x is selected, x becomes a child of y, the data for y still appears in the data block even though node x is selected in the tree). There seems to be something wrong with my triggers, but I can't figure out what.
Here are the triggers that I am using.
In the tree block, tree item:
-WHEN-TREE-NODE-SELECTED
set_block_property(v_data_block, default_where, 'global_id = ' | | v_org);
go_block(v_data_block);
execute_query;
In the data block, list item
-WHEN-LIST-CHANGED:
-- find the tree node and select it
node := Ftree.Find_Tree_Node(...)
Ftree.set_tree_selection(v_tree,node,Ftree.SELECT_ON);
-- update the data block to show data from the selected node
set_block_property('GREENPAGES_DIR', default_where, 'global_id = ' | | :greenpages_dir.global_id);
go_block('GREENPAGES_DIR');
execute_query;
Thanks for your help.

hi
i didn't try doing it.. i assume the the reasons can be:
1.check the value of the variable 'v_org' because 'w-t-n-s' trigger fires twice..
2. 'w-t-n-s' trigger is not firing eventhough u select it through ur code in the list item trigger.. if not firing, use execute_trigger('w-t-n-s') and remove the last set of code (update section) from the list item trigger..(assuming 'GREENPAGES_DIR' = v_data_block)
hope this helps u

Display and interact with a vi front panel on remote C++ app

Hello:
I am new to LV and need a little advice. I need to display a LabVIEW VI front panel in my C++ .Net application that users can interact with to view real-time spectrum data. The C++ app (client) must reside on a separate computer(s) from the VI so that the client can connect from anywhere around the world and interact with the VI.
I am not sure about the basic architecture that should accompany a good solution. We want to use TCP/IP but not DataSocket. I do not have access to Measurement Studio but I do have access to LabVIEW Professional Development System v 8.2. Can anyone provide suggestions on what I need to do in order to
1. Connect to my TCP server using my C++ client app - I have already written TCP client and server code which communicate but now I need to integrate LV
2. Get access to the VI sitting on that server
3. Send the VI front panel to the client for display
4. Allow the user to modify parameters on the front panel displayed on the C++ client, send those changes back to the server, and refresh the front panel displayed in the C++ client given the new parameters (I would like a real-time display of the spectrum to always be available)
Is this possible? Has anyone done this using C++ .NET in VS2005? Are there examples I can mimic or references that will help direct me? I have searched and searched through NI's help and found a lot of good stuff but I'm still feeling confused about the best way to utilize LV.
Thank you in advance!

One more question ... what if I could use Measurement Studio? The documentation seems to indicate that it's easy to create network applications and therefore it would be easy for me to re-create our VI's front panel using Measurement Studio components in my C++ app and then simply connect those components to the networked hardware (TCP/IP or DataSocket) that could be located anywhere in the world.
Depending on what components you are using in your LabVIEW panel, it is probably pretty easy to build a Measurment Studio application to look like a LV panel.
Given that, you could use network shared variables to move data across the network, no TCP programming necessary -- I think that this is pretty easy to do, but I don't know the specifics about variable programming in that environment. Also, you will probably need to add some smarts to the server side to make sure that it is reading to and writing from variables in an appropriate manner.
Question: why can't you just use LabVIEW for the client application also?

ORA -10567 : Redo is inconsistent with data block...

Hi All !!
Two days back I installed oracle 10g on windows XP and today my database is giving problem as it's in mount state and not opening for normal operation.
When I give command 'alter database open' then it's giving error ORA-10567 : Redo is inconsistent with data block...I have no earlier backup for database
and also no backup for any datafile. I crosschecked the status of datafile and found that there are block corruption in datafile 2 & 4 (users and undotbs01)..I used blockrecover coomand too for block corruption but not able to correct those blocks..plz suggest me that how can I fix this error ORA-10567.
Thanks
With Best Regards

Hi Ramesh,
I reckon you should try these out:
- identify the tablespace that file belongs to in the production db.
- put the that tablespace in backup mode on the prod db
- shutdown your standby database
- overwrite the problematic datafile with the corresponding datafile from production database
- put the tablespace above in end backup mode
- startup your standby database and issue the recover command.
Well, there you go. Your standby database should be all fine now.

You can purchase an adapter from apple that uses the monitor cable from the projector, its the same one that is probably connecting either your laptop or school workstation. On the projector control you might need to refresh the source.

Best way to display and interact with a tree

I am trying to create an interface that is similar to the interface on this website for the skill tree:http://www.pathofexile.com/passive-skill-tree. What is the best way to go about doing this and have the same or similar user interaction. ie. you click on a node and it activate or deactivates it. The movement of the tree and zooming on it would be nice as well. I am somewhat new to this and am not familiar with all of the libraries that the SDK has to offer if anyone could give me pointers on where to look that would be great. I would like to try to stay away from webView as I am thinking about features I want to add. Thanks in advance just want to see what a good way to do this is.

Hierarchical Tree and keyboard navigation

Does anyone know how to use Hierarchical Trees with keyboards, or to disable keyboard actions? (forms 9.0.4)
My form has a tree which does processing in a When-Tree-Node-Selected trigger to populate some blocks depending on the selected node. If the user selects nodes with the mouse then all is fine, but if they move between nodes with the keyboard then the processing for each selected node is only run the next time a node is selected with the mouse. This means the data for each node will flash up in the blocks for a split second when the mouse is next used.
I've tried Key-Up/Key-Down triggers to prevent keyboard navigation, but they don't fire. Setting Keyboard Navigable to false doesn't fix it either.
Using the When-Tree-Node-Activated trigger doesn't help. The online help says this trigger fires when the user presses Enter or double-clicks a node. I find that each node for which Enter was pressed is processed only when the user next double-clicks a node, and the node they double-click is not processed.

Data Concurrency and Consistency ( SCN , DATA block)

Hi guys, i am getting very very very confused about how oracle implement consistency / multiversioning with regards to SCN in a data block and transaction list in the data block..
I will list out what i know so you guys can gauge me on where i am..
When a SELECT statement is issued, SCN for the select query is determined. Then Blocks with higher SCN are rebuilt from the RBS.
Q1) The SCN in the block implied here - is it different from the SCNs in the transaction list of the block ? where is this SCN store ? where is the transaction list store ? how is the SCN of the block related with the SCNs in the transaction list of the block ?
Q2) can someone tell me what happen to the BLOCK SCN and the transaction list
of the BLOCK when a transaction start to update to a row in the block occurs.
Q3) If the BLOCK SCN reflects the latest change made to the block and If the SCN of the block is higher then the SCN of the SELECT query, it means that the block has change since the start of the SELECT query, but it DOESNT mean that the row (data) that the SELECT query requires has changed.
Therefore why cant ORACLE just check to see whether the row has changed and if it has, rebuilt a block from the RBS ?
Q4) when ORACLE compares the BLOCK SCN, does it only SCAN for the BLOCK SCN or does it also SEARCH through the TRANSACTION LIST ? or it does both ? and why ?
Q5) is transaction SCN same as Transaction ID ? which is store in the RBS , the transaction SCN or ID ?
Q6) in short i am confuse with the relationship between BLOCK SCN, transaction list SCN, their location, their usage and relationship of the BLOCK SCN and transaction list when doing a SELECT, their link with RBS..
any gurus clear to give me a clearer view of what is actually happening ?

Hi Aman
Hmm agreed.So when commit is issued , what happens at that time?Simply put:
- The SCN for the transaction is determined.
- The transaction is marked as committed in the undo header (the commit SCN is also stored in the undo header).
- If fast cleanout takes place, the commit SCN is also stored in the ITL. If not, the ITL (i.e. the modified data blocks) are not modified.
So at commit, Oracle will replace the begin scn in the ITL with this scn
and this will tell that the block is finally committed is it?The ITL does not contain the begin SCN. The undo header (specifically the transaction table) contains it.
I lost here.In the ITL , the scn is transaction SCN or commit scn?As I just wrote, the ITL contains (if the cleanout occured) the commit SCN.
This sounds like high RBA information?What is RBA?
Commit SCNThis is the SCN associated with a committed transaction.
Begin SCNThis is the SCN at which a transaction started.
Transaction SCNAs I wrote, IMO, this is the same as the commit SCN.
Also please explain that what exactly the ITL stores?If you print an ITL slot, you see the following information:
BBED> print ktbbhitl[0]
struct ktbbhitl[0], 24 bytes     @44
      struct ktbitxid, 8 bytes    @44
         ub2 kxidusn              @44       0x0009
         ub2 kxidslt              @46       0x002e
         ub4 kxidsqn              @48       0x0000fe77
      struct ktbituba, 8 bytes    @52

         ub1 kubarec              @58       0x4e
      ub2 ktbitflg                @60       0x2045 (KTBFUPB)
      union _ktbitun, 2 bytes     @62
         b2 _ktbitfsc             @62       0
         ub2 _ktbitwrp            @62       0x0000
      ub4 ktbitbas                @64       0x06f4c2a3- ktbitxid --> XID, the transaction holding the ITL slot
- ktbituba --> UBA, used to locate the undo information
- ktbitflg --> flags (active, committed, cleaned out, ...)
- _ktbitfsc --> free space generated by this transaction in this block
- _ktbitwrp+ktbitbas --> commit SCN

Can i use flash for ui and interact with c++ builder for the rest

i know flash can be used in c# in visual studio but i dont remember a thing of this interaction.
is it possible to interact with c++ builder and how?
the scenario is simple
use flash for UI (showing-viewing data) maybe for a kiosk or something without mouse simply with touch input,
use c++ builder for the rest , database connection data proccessing etc
any info will be greatly appreciated
thanks

I would advise proper punctuation and grammar on a public forum, but to answer your questions, yes, yes you can! Flash can be used to produce any commercial imagery or animations for the purpose of making profit, as long as you have a valid license you purchased from Adobe. You bought it, you can use it for whatever you want.
By "book", I assume you mean the "tutorial" book series made by Adobe? If so, the name of the series is "Classroom in a Book", there's one for each versions of Flash. Personally it hasn't been of much use and I would advise simply practicing by yourself and getting familiar with the tools. Look for online tutorials and publicly available projects and see how they work.

This is the beginning of the data block dump. The first line tells us that we are dumping file#3, starting at block# 10 (minblk), and finishing with block# 10 (maxblk). Had we dumped more than one data block, these values would represent a range. The relative data block address (rdba) is 0x00c0000a. For more information on the rdba, refer to a later section in this paper. At the end of this line, we can see in parentheses that the rdba corresponds to file# 3, block# 10 (3/10).
The third line describes the SCN of the data block. In our case, the SCN is 0x0000.00046911. The tail of the data block is composed of the last two bytes of the SCN (6911) appended with the type (06) and the sequence (02). If the decomposition of the tail does not match these three values, then the system knows that the block is inconsistent and needs to be recovered. While this tail value shows up at the beginning of the block dump, it is physically stored at the end of the data block.
The block type shows up on the fourth line. Some of the valid types correspond to the following table:
     Type     Meaning
     0x02     undo block
0x06     table or index data block
0x0e     undo segment header

CRM ABAP development and interaction with SAP R/3

Hi Experts,
I am an ABAPer and have close to 3 years of development experience in ABAP, now i was trying to understand how exactly a CRM system is intergrated with SAP R/3 . Below are few of the basic question i have
1. How does R/3 interact with CRM, searching in the forum i just got to know its through RFC . Can anyone give me specific technical details like how R/3 and CRM interact in a real time scenario .
2. Ca any one also give me an real time development example that was done in CRM to interact with SAP R/3 and explain me the basic steps involved in it, this might give me clear picture of how developments happen in CRM and also how CRM and SAP interacts with each other .
Your quick response would be greatly appreciated .
Regard's
Sudheer V

with repect to programming , it is similar to R/3 ABAP devlopment . It all depends on scenarios:
1) For eaxmple we use BADI's to put some extra validations / additional data when you are creation order
2) unlike R/3 where we use SAP GUI trnsactions for creating orders, in CRM we have IC web client techonolgy where we can create orders through web.This is based on BSP technology. In order to add additinal fields on the screen for we use easy enhancment workbench tool(EEWB).this is something new in CRM when compared to R/3.

Dbwr and writing undo data block

hi guys,
If dbwr was to write a dirty block to disk, would it also have to write the dirty uno data block that contains the before value of our database block to disk too?
Thanks

The first thing to remember is that recovery depends on the REDO, not the UNDO, so technilcally it doesn't matter whether dbwr manages to write neither, one, or both of the two blocks to disc to avoid any problems with crash recovery. This should give you a clue that dbwr doesn't HAVE to write the undo block at the same time as the data block.
In practice, it is possible that both blocks will be written virtually simultaneously because the two blocks will have been modified at the same instant and therefore could be written during the same 3-second timeout write (continuous checkpoint). It is also possible, though, for the undo block to be written some time before the data block, or some time after the data block - it all depends on what activity has been going at about the same time.

Creating "Control Combo Box " Relation with data block

Hi all dears
i am switching from C# to oracle developer for joining gulf net software house, i have a problem regarding master detail data
the senerio is
"List items" control Filled programatically as under shortly:-
rg_id := create_group_from_query('myrg', 'select dname a, dname b from dept');
populate_group(rg_id);
populate_list('mylist', rg_id);
using this i fill my combo box during new form instance trigger
i have created a datablock emp through wizard which can show 10 record.
now
Problem 1
i want to show records on form when user select any dept from combo box.
Problem 2
if i create group from query and in select statement is like this "select dname, dpetno from dept" the record group is created successfully but i am unable to populate_list due to different data type colums in record group how i will populate list so that List items Labels are department name and value is department no
Thanks in advance for persual

Hi dears all
I have solved this problem my self
1. select dept name form combo box and the data block shows the emp's of concern depat
solution
create a data block of emp table through wizard
create its table view and show 10 records
go to datablock i consider its name "emp" datablock properties
in Where clause condition specify deptno = : my_combo_box;
now go to combo box when item changed event
go_bolck("emp);
execute_query;

Yes I did use the wizard,
I agve it the package.proc name for query.
it pulled up the field delivery ID,
Hit finish, because I do not need update/delete/inserts.
the query data source columns and arguments was defaulted correctly.
THe QUERY-PROCEDURE was built by default.
It is giving me an error though: wrong number or types of arguments in call to POPULATE_BLOCK..
DECLARE
