How to insert queue element from C

I want to insert a single queue element into a LabView Queue from C (from a DLL).
The only thing I found is How to set an Labview-Occurence from C. I assume that I have to do that in 2 steps: 1. copy the string data into the queue with a push/pop command. 2. Set the Occurence from the queue to notify waiting queue elements.
I only need to know how to realize this in the exactly way. (internals of Queue handling, Queue structure, example code, ....)
I'm using LabView 6.0.2 with WinNT 4.0
Thank's for help.

Robert,
You currently cannot access Queue elements from external code. We hope to add this feature to a future version.

What does this mean?
So I browse through forum & i got to know that i need to initial the UTL_FILE_DIR ="C:/OracleProject" in init.ora
So can i edit the init.ora with notepad.When i tried to do that it says permission denied
In my system it shows the init.ora file in path C:\oraclexe\app\oracle\product\10.2.0\server\config\scripts
but there is also other file initXETemp in the same path do i need to do the changes in it.
I have tried even editing the SPFILE as mentioned below:
C:\oraclexe\app\oracle\product\10.2.0\server\dbs\SPFILEEXE - I had edit this file using notepad & set the value of UTL_FILE_DIR ="C:/OracleProject". So next time when i restarted i'm unable to log on to the database.
So i had reinstall the software again.

How to insert select columns from one internal table to another

Hi,
How to insert select columns from one internal table to another based on condition as we do from a standart table to internal table.
regards,
Sriram

Hi,
If your question is for copying data from 1 int table to other ;
we can use
APPEND LINES OF it_1 TO it_2.
or if they have different columns then:
loop at it_1 into wa_it1.
move wa_it1-data to wa_it2-d1.
apped wa_it2 to it_2.
clear wa_it2.
endloop.

How to insert a value from sequence in Bussiness Components?

How to insert a value from sequence in Bussiness Components?
I would like to do it, but without a triger that would do it before insert.
I know that there is a type DBSequence in BC where you can insert a sequence name but it does not work when I type there my sequence name.
Do you now how to fix that problem?
Bart.

The newer way to do it is to make the type DBSequence and enter the name of the Sequence object in the sequence field. It must match the same name of the sequence object in the database. Next, you have to create a before insert for each row trigger on the table. Basically, something like this:
CREATE OR REPLACE TRIGGER TGB_THEME_SEQ
BEFORE INSERT ON THEME
FOR EACH ROW
DECLARE
BEGIN
-- Assign the id from the sequence if null
     IF( :new.theme_id IS NULL ) THEN
          SELECT THEME_ID_SEQ.nextval
          INTO :new.theme_id
          FROM dual;
     END IF;
END;
In the above example, THEME_ID_SEQ is the seuence object name in the database. If you have the name right but it still fails, then the user you are logging in as probably doesn't have access to the sequence in the database.
Hope this helps.

How to reinstall Photoshop Elements from old Pc into Mac?

How do I reintall Photoshop Elements Windows version into my new Mac. PC was stolen.

I looked at it, Barbara, but you can't download 9 without the discs. I
originally downloaded it online and Adobe now tells me it only has 10 to
download.

Did you not look at the link in the thread in my last post, Lorna?
When you buy software it's your responsibility to keep the media against
future reinstallations, whether you purchase via download or on disc. If
you registered your software, for PSE 9 you may still find a download
link in your adobe store account, if you purchased PSE that way, also.

How to insert database elements?

Hi all,
could you please tell me .. how to add insert command in our abap program to insert the database elements? and also we want to know whether we can add the same insert statement we are using on the oracle.we tried with that command but it cause some problem.
INSERT INTO ZJEYC1 VALUES (' & CUSTNO ' , ' & CUSTNAME & ' , ' & CUSTADDRESS & ' , ' & CUSTMOB & ').
is it correct?...
if no please send me the code...

INSERT - Insert in a database table
Variants
1. INSERT INTO dbtab VALUES wa. or
INSERT INTO (dbtabname) VALUES wa.
2. INSERT dbtab. or
INSERT *dbtab. or
INSERT (dbtabname) ...
3. INSERT dbtab FROM TABLE itab. or
INSERT (dbtabname) FROM TABLE itab.
Effect
Inserts new lines in a database table .
You can specify the name of the database table either in the program itself in the form dbtab or at runtime as the contents of the field dbtabname . In both cases, the database table must be defined in the ABAP/4 Dictionary . If the program contains the name of the database table, it must also include a corresponding TABLES statement. Normally, lines are inserted only in the current client. Data can only be inserted using a view if the view refers to a single table and was defined in the ABAP/4 Dictionary with the maintenance status "No restriction".
INSERT belongs to the Open SQL command set.
Notes
You cannot insert a line if a line with the same primary key already exists or if a UNIQUE index already has a line with identical key field values.
When inserting lines using a view , all fields of the database table that are not in the view are set to their initial value (see TABLES ) - if they were defined with NOT NULL in the ABAP/4 Dictionary . Otherwise they are set to NULL .
Since the INSERT statement does not perform authorization checks , you must program these yourself.
Lines specified in the INSERT command are not actually added to the database table until after the next ROLLBACK WORK . Lines added within a transaction remain locked until the transaction has finished. The end of a transaction is either a COMMIT WORK , where all database changes performed within the transaction are made irrevocable, or a ROLLBACK WORK , which cancels all database changes performed within the transaction.
Variant 1
INSERT INTO dbtab VALUES wa. or
INSERT INTO (dbtabname) VALUES wa.
Addition
... CLIENT SPECIFIED
Effect
Inserts one line into a database table.
The line to be inserted is taken from the work area wa and the data read from left to right according to the structure of the table work area dbtab (see TABLES ). Here, the structure of wa is not taken into account. For this reason, the work area wa must be at least as wide (see DATA ) as the table work area dbtab and the alignment of the work area wa must correspond to the alignment of the table work area. Otherwise, a runtime error occurs.
When the command has been executed, the system field SY-DBCNT contains the number of inserted lines (0 or 1).
The return code value is set as follows:
SY-SUBRC = 0 Line was successfully inserted.
SY_SUBRC = 4 Line could not be inserted since a line with the same key already exists.
Example
Insert the customer Robinson in the current client:
    TABLES SCUSTOM.
    SCUSTOM-ID        = '12400177'.
    SCUSTOM-NAME      = 'Robinson'.
    SCUSTOM-POSTCODE = '69542'.
    SCUSTOM-CITY      = 'Heidelberg'.
    SCUSTOM-CUSTTYPE = 'P'.
    SCUSTOM-DISCOUNT = '003'.
    SCUSTOM-TELEPHONE = '06201/44889'.
    INSERT INTO SCUSTOM VALUES SCUSTOM.
Addition
... CLIENT SPECIFIED
Effect
Switches off automatic client handling. This allows you to insert data across all clients even when dealing with client-specific tables. The client field is then treated like a normal table field which you can program to accept values in the work area wa that contains the line to be inserted.
The addition CLIENT SPECIFIED must be specified immediately after the name of the database table.
Example
Insert the customer Robinson in client 2:
    TABLES SCUSTOM.
    SCUSTOM-MANDT     = '002'.
    SCUSTOM-ID        = '12400177'.
    SCUSTOM-NAME      = 'Robinson'.
    SCUSTOM-POSTCODE = '69542'.
    SCUSTOM-CITY      = 'Heidelberg'.
    SCUSTOM-CUSTTYPE = 'P'.
    SCUSTOM-DISCOUNT = '003'.
    SCUSTOM-TELEPHONE = '06201/44889'.
    INSERT INTO SCUSTOM CLIENT SPECIFIED VALUES SCUSTOM.
Variant 2
INSERT dbtab. or
INSERT *dbtab. or
INSERT (dbtabname) ...
Additions
1. ... FROM wa
2. ... CLIENT SPECIFIED
Effect
These are the SAP -specific short forms for the statements explained under variant 1.
INSERT INTO dbtab VALUES dbtab. or
INSERT INTO dbtab VALUES *dbtab. or
INSERT INTO (dbtabname) VALUES wa.
When the command has been executed, the system field SY-DBCNT contains the number of inserted lines (0 or 1).
The return code value is set as follows:
SY-SUBRC = 0 Line successfully inserted.
SY_SUBRC = 4 Line could not be inserted, since a line with the same key already exists.
Example
Add a line to a database table:
    TABLES SAIRPORT.
    SAIRPORT-ID   = 'NEW'.
    SAIRPORT-NAME = 'NEWPORT APT'.
    INSERT SAIRPORT.
Addition 1
... FROM wa
Effect
The values for the line to be inserted are not taken from the table work area dbtab , but from the explicitly specified work area wa . The work area wa must also satisfy the conditions described in variant 1. As with this variant, the addition allows you to specify the name of the database table directly or indirectly.
Note
If a work area is not explicitly specified, the values for the line to be inserted are taken from the table work area dbtab if the statement is in a FORM or FUNCTION where the table work area is stored in a formal parameter or local variable of the same name.
Addition 2
... CLIENT SPECIFIED
Effect
As for variant 1.
Variant 3
INSERT dbtab FROM TABLE itab. or
INSERT (dbtabname) FROM TABLE itab.
Additions
... CLIENT SPECIFIED
... ACCEPTING DUPLICATE KEYS
Effect
Mass insert: Inserzts all lines of the internal table itab in a single operation. The lines of itab must satisfy the same conditions as the work area wa in variant 1.
When the command has been executed, the system field SY-DBCNT contains the number of inserted lines.
The return code value is set as follows:
SY-SUBRC = 0 All lines successfully inserted. Any other result causes a runtime error .
Note
If the internal table itab is empty, SY-SUBRC and SY-DBCNT are set to 0 after the call.
Addition 1
... CLIENT SPECIFIED
Effect
As for variant 1.
Addition 2
... ACCEPTING DUPLICATE KEYS
Effect
If a line cannot be inserted, the processing does not terminate with a runtime error, but the return code value of SY-SUBRC is merely set to 4. All the remaining lines are inserted when the command is executed.

How do I extract elements from a file?

Let's say I have a larger file with several layers and various elements on the layers - like a web page layout.
On 1 layer the is top logo.
I am trying to extract just that 1 part and save for web as small jpg or png and put that one pic in my web design app.
Q: How do I easily exctract / export / save for web (small version) just that one part?

If you do a lot of saving graphic elements from web page mock-ups, it's worth reading up on using slices.
Also have a look at layer comps. Combining the two enables you to save all the graphic elements of the web page (including various roll-over states) from one master file.

How to insert special character from Oracle form builder 10g

Dear all,
I need help. how to insert special character like 'Superscript or Subscript ' from oracle form builder 10g. I had try in Oracle form builder 6i with press ALT+ASCII code in the text item and it work, but in the oracle form builder 10g this method doesn't work... would you like to help me...somebody please...
Best Regard,
Dedy P.T.

What do you mean by insert ... from Forms Builder? Do you mean you want to add it as text in a string of pl/sql code or as part of boiler plate text (label) or a value on the Property Palette?
For special characters you would need set NLS_LANG to something that would support the characters you want to use. For the Builder to see the change, you would need to set NLS_LANG to something like:
NLS_LANG=AMERICAN_AMERICA.UTF8
This can be done in the Windows Registry or system. As I mentioned, this will only apply to the Builder and will have nothing to do with a running form. For running forms you would need to set this in default.env. As for things like super and sub scripts, these are font formats and not necessarily characters. For the most part, I don't believe these are supported in Forms.

How to insert cropped images from photoshop without the white background

Basically all I want to do is take a peice of writing from a video and insert it into another video. To do this I've took a screenshot of the font from the video and imported it into photoshop. I've then cropped/cut/took the the peice of writing I want, letter by letter. I want to be able to insert it into another video, but whenever I attempt to do it, I have the default white background of photoshop. Is there anyway to insert an image from photoshop, without taking the background with it, or even insert a layer from photoshop straight into final cut pro? Sorry if this is confusing.

I don't think so. I cropped the letters, put them each an individual file, removed the background, saved them as a TIF then tried to import them onto Final Cut Pro, but a white background still appeared in the TIF file. Basically I just want to make the background transparent I believe.

How to insert data elements automatically?

Hi,
I am developing an ADF (JSF, BC) application with JDev 10. What I've done up to now is an creation form, where you can put in the attributes of an object which are stored to the database by clicking the commit-button.
This works well. What do I have to do if I want to automically create a primary key which should be added to the same row by clicking the commit-button? In general I would like to know, how to automatically write elements to the database in case of certain events. Is this realized with mananged beans or do I have to alter the class of the entity object. I've searched for this toppic in the Developers Guide but found nothing.
I don't have much experience with Java, so if this problem could be solved with Java-Code, it would be nice if you could give me a source where I can read how to program this.
Thank you in advance.

Use a database sequence to create the unique key and use the DBSequence type for the attribute in your EO that maps to this key.
Search for DBSequence in the ADF Developer Guide and you'll see it.

How to insert 10 files from a directory to database,can i use dbms_lob??

I want to load 10files in my local drive into a table...how to do this.I'm able to do this individually using dbms_lob.loadfromfile and bfil but ,I want to copy all the files i that drive at time to my table...Is there any way to do this..?

Okay... Here is some sample code that will help you store the files in binary format into db tables.
create table t_blob(bid integer, blbdata blob);
select * from t_blob;
create or replace directory ext_tab_dir as 'C:\Oracle\ExtTab_Dir';
grant read, write on directory ext_tab_dir to priya;

/I haven't used the wrap utility yet, so not much hands on with it. I guess the wrap utility at the OS level. Not sure if it will work at SQL prompt.

Hi,
Till now i tried the following code which give null pointer exception at following line
element.getParentNode().removeChild(element);
     public String removeUserByID(String id) throws Exception{
               DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
             DocumentBuilder builder = factory.newDocumentBuilder();
             TransformerFactory tFactory = TransformerFactory.newInstance();
             Transformer tFormer = tFactory.newTransformer();
               doc = builder.parse(usersXml);
             Element element = (Element)doc.getElementsByTagName("user id="+id).item(0);
//             Remove the node
             element.getParentNode().removeChild(element);
//             Normalize the DOM tree to combine all adjacent nodes
             doc.normalize();
             FileOutputStream fos = new FileOutputStream(this.usersXml);
               XMLOutputter out = new XMLOutputter();
               out.output(((org.jdom.Document)doc), fos);
          /*     Source source = new DOMSource(doc);
             Result dest = new StreamResult(System.out);
             tFormer.transform(source, dest);
             System.out.println();
             return "true";

How to insert unicode charater from SQLPLUS

Hi all,
My problem is following :
I want to store unicode character in a column of table so I create table with command : CREATE TABLE PERSON( ID NUMBER(4) NOT NULL ,NAME NVARCHAR2(64) NOT NULL).
NLS_CHARACTERSET is set in DB :
SQL> SELECT * FROM NLS_DATABASE_PARAMETERS;
PARAMETER VALUE
NLS_LANGUAGE AMERICAN
NLS_TERRITORY AMERICA
NLS_CURRENCY $
NLS_ISO_CURRENCY AMERICA
NLS_NUMERIC_CHARACTERS .,
NLS_CHARACTERSET WE8ISO8859P1
NLS_CALENDAR GREGORIAN
NLS_DATE_FORMAT DD-MON-RR
NLS_DATE_LANGUAGE AMERICAN
NLS_SORT BINARY
NLS_TIME_FORMAT HH.MI.SSXFF AM
PARAMETER VALUE
NLS_TIMESTAMP_FORMAT DD-MON-RR HH.MI.SSXFF AM
NLS_TIME_TZ_FORMAT HH.MI.SSXFF AM TZH:TZM
NLS_TIMESTAMP_TZ_FORMAT DD-MON-RR HH.MI.SSXFF AM TZH:TZM
NLS_DUAL_CURRENCY $
NLS_COMP BINARY
NLS_NCHAR_CHARACTERSET UTF8
NLS_RDBMS_VERSION 8.1.7.0.0
18 rows selected.
when I insert data into above table (PERSON) with none unicode character is OK, but I failed with unicode character.
Can anyone help me to solve this proplem?
Thank you so much for any hints
Pls email me at : [email protected]

NLS_CHARACTERSET WE8ISO8859P1 is a western eurpoean character set (without the Euro symbol and about !# other funky characters being supported - use NLS_CHARACTERSET WE8ISO8859P1% if you want the Euro symbol, sorry just a sidenote). Anyways, this will need to be changed to UTF* before it can store Unicode characters. There are various ways to do this, but the best option is probably to export the entire database, create scripts to recreate all tablespaces and datafiles, drop the database, recreate the database in UTF8, then import the export file. There's a lot of little 'gotchas' involved so be prepared for it not to work the first time. But if it doesn't work, you can always create the database again with NLS_CHARACTERSET WE8ISO8859P1 and reimport so everything is back to how it was.
