Vi or any function that closes the VI abruptly

Hi,
Is there any vi or function that stops running the main vi abruptly upon true.(inside the main vi there may be a subvi that has a while loop meaning it runs indefinitely)
only the main vi should be closed not the LabVIEW insatance.I'm using LabVIEW 2009

There are several options for this, depending on the overall architcture of your software. Most often, such a request makes sense in a producer/consumer environment.
So the task is to inform the producer and the consumer to shutdown. Even there you have different options:
a) The producer inits the shutdown. This is very easy since it follows the idea of produce/consumer.
b) If the consumer should init the shutdown, you have to include a "messaging mechanism" for the consumer in order to shutdown the producer. Custom user events come quite handy here....
c) You have some kind of watchdog for this feature. The watchdogs takes care about shutting down other parts of the application using user events or notifications. This can be used in producer/consumer as well as in other design patterns.
Sure, the shutdown is not really "immediate", but if there are certain security requirements involved (e.g. robotics emergency shutdown), you must not have a software shutdown working within non-deterministic systems! If you have such an environment, the only acceptable "softwaresolution" would work on FPGAs.......

Is there any function that returns the latest DDL statement

can anyone tell me if there is any FUNCTION that returns latest DDL statement performed in a schema.
OR
if there is any TABLE that will be populated with latest
DDL statement in schema.
THANK YOU.

The table all_objects (and/or dba_objects) contains a column called last_ddl_time. Thus, a query like
scott@jcave > SELECT max(last_ddl_time)
2 FROM all_objects
3 WHERE owner = 'SCOTT';
MAX(LAST_DDL_TI
28-NOV-03will tell you the last time any object owned by SCOTT had DDL issued against it.

FU ADDRESS_INTO_PRINTFORM        ADDRESS_TYPE
Text
Address type: 1,2,3 or ' '(default)
Description
There are three address types:
Address type '1': 'Normal' address (company or organization); the address structure used in most SAP applications as 'Address'.
Address type '2': Address of a person
Address type '3': Work address, usually the address of a contact person in a company
The default address type SPACE is treated as type '1' and is required for the upwards compatibility of the function module.
The interface parameters ADRSWA_IN and ADRSWA_OUT are only used in address type SPACE.
The other address types use:
ADDRESS_1 or ADDRESS_2 or ADDRESS_3 for the attributes, and
SENDER_COUNTRY, RECEIVER_LANGUAGE, NUMBER_OF_LINES, STREET_HAS_PRIORITY and LINE_PRIORITY for control.
The parameters COUNTRY_NAME_IN_RECEIVER_LANGU, LANGUAGE_FOR_COUNTRY_NAME and NO_UPPER_CASE_FOR_CITY are address type-independent.
The address attributes can be read directly instead of being passed in the structures ADDRESS1/2/3, if the address is in the Central Address Management tables.
The Business Address Services keys must be passed instead of the structures ADDRESS1/2/3:
Address type 1: ADDRESS_NUMBER
Address type 2: ADDRESS_NUMBER and PERSON_NUMBER
Address type 3: ADDRESS_NUMBER and PERSON_NUMBER

Looking for a function that returns the currently opened document type

Dear SAP gurus
I have a user exit for transaction VA02. In VA02, when I click on button (Item details-configuration),
it launches a URL in a browser. I am asked to add to the URL, values like Document Type, Document Number
and Line Item Number.
I can get Document Number and Line Item Number from the presently opened Sales Document by using the standard Function 'CUCB_GET_OWNER_OF_CFG'.
However, I am not able get the value of Document Type. Is there any function that will give me
the value of the Document type of the present document that is open.
Any feedback/Suggestion will be highly appreciated.
Thanks
Ram

If you're in a VA02 user exit, the document type should be in VBAK-AUART, if I remember the field name correctly. I would think that ANYWHERE in VA02, that field will be available to you.
If you want the text of the document type, forward navigate from vbak-auart data element to the domain and look at the values...there'll be a config (T) table (and you may need to add T to the end to get the associated text table) that describes the document type in your system's language, like:
E OR Order
or something like that... Sorry, in my installation, we don't use the logistics modules, so I'm writing from memory.

Is there any function that....

Hello friends
I wrote a ABAP program to print the PL (Part List). But while printing it jst takes 25 lines in the ckt refence else it don't print it. This is becoz of the reason that while printing it takes 1st ckt refence then 20 blank spaces then next ckt and so on. and it prints maximum of 500 characters. So if we have more than 25 lines we face problem. Is there any function that bypasses these 20 blank spaces and only consider the ckt refences. Plz help me in this. If possible sent me the code for it.
Thnx
Rakhi

I think you should use a pl/sql function for this.
Nah ... just joking.
I'd be tempted to just use a union all statement to return the seven literals. People will look at it and know exactly what it does.Yeah, agreed, I was just demonstrating that the format mask of a to_char(..., 'Day') pads with spaces, which seems to have been missed in the above answers. ;)

MacBook no longer recognizes any devices that require the USB port (mouse, iPod, etc.)

After doing my latest software update, my MacBook no longer recognizes any devices that require the USB port (mouse, iPod, etc.). I've restarted the computer and that didn't help. Any thoughts on what to try? (I've already restarted the computer.)

Try using the procedures in this article to eject the disk.
Best of luck.

Create a Button that Closes the Presentation

All, I want a button on the last slide of my presentation that, when clicked, will close the browser window in which the presentation is playing. Will this involve Javascript? I tried some, but I probably screwed it up because it won't work. Some step-by-step guidance would be much appreciated, should someone have a few moments to guide me. Trying to make something more obvious than the X button on the playbar. Thanks so much!

Hi there
As explained in the Frequently Encountered Issues topic, closing the window is "iffy" and depends on different factors.
The simplest approach is to avoid JavaScript altogether. Just configure the project to close when it completes. Then if you want a button that closes the project, configure it to jump to the last slide. Time that last slide super short. The net result will be that the user clicks the button, it jumps to the last slide for a split second, then if the project is capable of closing, it closes!
Cheers... Rick

YOu can try resetting your network or a reboot. To reboot hold down the home/power button together until you see the apple logo and then release. Wait for the phone to boot back up, you won't lose any data.
