2d Direct draw, and how to find out if the application is a java apps

I am running a banner application that was written in java. And in some instances, we are seeing the banner flicker every 5 seconds or 10 seconds. The banner application is written by some other government branch and on their documentation they say that the flickering is due to java's 2D directdraw used by some other java application (not their banner application). I personally haven't seen this on our test VMs but it is being seen on some physical workstation at the client site.
I am trying to find out the application that is using java's 2D directdraw in our environment. Some of the question I have is
1) Is there anyway to find out what application is using java 2D directdraw? ( I know how to disabled it globally for java but don't want to do that, I would rather just disable it for one application than disabling it on all java application)
2) Is there anyway to find out what applications are depended in JVM on a machine? So that I can narrow the list of application to test.
3) Is there anyway to find out if a application is written in java. Our environments have a lot of applications installed on them and I'm not sure which one use JVM and which one don't. If there is a way to know that then I can narrow down my issue and try to solve it.
Thank you for your help, I really appreciate it,
Sudeep.

Hi,
if the database is running, start a sqlplus session. You will see in the banner something like '64Bit Production' (for 64-bit) or only 'Production' for 32-bit. Alternatively, especially if the database is not running, go to $ORACLE_HOME/bin and type 'file oracle'. The returning strings shows either 32-bit or 64-bit.
Best regards

Is it possible and how to find out what host, if any, is connected to a remote PXI prior to switching execution target programmatically or in devlopment environment?

Is it possible and how to find out what host, if any, is connected to a remote PXI prior to switching execution target programmatically or in devlopment environment?

This functionality is not available in LabVIEW RT. If you attempt to switch execution target to an RT controller already targetted by someone else, it will tell you too many hosts are connected and fail. Of course if it allows you to switch, then no one was connected. By attempting to switch execution target you can use the message above to determine if anyone is targetted or not, but if someone is, there is no way to determine who.
If you are concerned about this sort of thing, you might check the RT target options in LabVIEW RT to change the IP access list for hosts that are allowed to switch execution target to it.

How to find out about the SMTP Server

Hi,
I have been trying to configure groupware in the portal - in particular I want to enable the sending of emails through the portal. I already have a how-to-guide that that seems to explain the steps quite well. However, it mentions that I need to know the SMTP Server of the email. Can you tell me how to find out about the SMTP Server? Where do I need to look for the name of it?
Thank you and regards,
Katharina

Hi Katharina,
you need the SMTP server of your company. This means you can't look for it in the portal, but have to ask the responsible person in your company.

When I open iPhoto 9.2.1 it says that my library needs to be upgraded but when I upgrade the library I am trying to open (33 GB worth of pictures from 2006) the new application says it cannot read the files and how to find them on the system to reimport?!

When I open iPhoto 9.2.1 it says that my library needs to be upgraded but when I upgrade the library I am trying to open (33 GB worth of pictures from 2006) the new application says it cannot read the files and how to find them on the system to reimport?! and then I'd like to erase the original files since the space requirement is huge!!!! Why is upgrading software iPhoto such a pain. I've gotta get a presentation done and all I get for my money is roadblock!!!

hello, it sounds like the library is damaged.
Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.

How to find out whether the system user is a vendor or a purchaser

Hi,
I am working in SRM 5.0. I have a requirement that some fields of Bid invitation can be visible by purchaser but not to bidder.
How to find out whether the system user (user id though which system logged in) is a vendor or a purchaser. Kindly help me to resolve this issue.

check his role.
is surrogate bidding available for that bidder.
via surrogate bid , purchaser can submit bid on behalf of the bidder.
masa is correct
pposa_bbp - search via user . so he might be a purchaser.
maintain business partner -supply your bidder bp number -edit
go to bidder data .Under bidder data you must flag "PERMIT PROXY BIDDING"

On your iPad go to the App Store icon, Tap on the Purchased Tab.
It will show you all the Apps that have been bought with the Apple Id currently in use by the iPad.
Assuming its the same one being used on the iPhone, you should be able to find the App there.
To further help you find it you can tap on the "Not on this iPad" button to limit the results to just Apps not currenlty installed on your iPad.

How to find out that the card in a given NIDAQ slot is a DSA card?

In the description of DAQ_Op(...) function in the traditional NIDAQ function reference one reads:
"buffer" is an integer array. "buffer" has a length equal to or greater than count.
When DAQ_Op returns with an error number equal to zero, buffer contains the acquired data.
For DSA devices, buffer should be an array of i32. These devices return the data
in a 32-bit format in which the data bits are in the most significant bits.
Question 1: How to find out programmatically that the card in a given NIDAQ slot is a DSA card?
Question 2: How many MSB carry the information? How do I find out bit-ness of the card (programmatically)?
The obvious solution to create and keep updated the table/fil
e with the data for all existing DAQ cards is unacceptable. This could be maintained by NI itself, but not by 3rd party developpers, like me.

Bryan, thanks for your answer.
I hope that my NIDAQ-wish-list will not only reach NIDAQ developers but some of it will be implemented in the next versions of NIDAQ.
I should say that I am quite pessimistic because I was sending similar requests via German support few YEARS ago and I am still even do not know whether they reached developers or not. Even if yes, the present NIDAQ still does not have these functions and this means that NI takes 2..4 years to react on the feedback.
At the moment I have no choice, and I do maintain self-made info file (nidaq.ini). But beleive me, it is a pain in the @ss to scan help files and manuals of the DAQ cards which I've never seen just to include info in nidaq.ini. And when my customers of a brand new NIDAQ ca
rd call and wonder why the card is not reacognized by my application correctly, I tell to them that this is basically fault of NI. Because NI provides no way to get card info. I am doing my best analysing error codes, but it does not help in all cases. Sorry, guys, but you left no choice to me.
As for NIDAQmx, this is not a solution either. I am not going to rewrite my existing and working rather big application. It could be a good suggestion for those who just starts developing a new applications from the scratch, but not for those who almost finished it. Even for those who begin now, NIDAQmx may not be a good choice, because, as I saw in this forum, it does not support all cards that are supported by NIDAQ. It also looks like that instead of improoving, developing and fixing NIDAQ, NI dicided to change API completely. It is not yet clear to me whether NIDAQmx is supposed to substitute NIDAQ in the future or not. If not, I would concentrate on improoving trad. NIDAQ. If yes, it wou
ld be a disaster for many developers. :-(
Anyway, I hope that the interaction between NIDAQ team and application developpers will be improoved, and we will see some results of this feedback.

How to find out that the database table is empty

Hello all,
How to find out in ABAP in the best performant way, that the database table is empty. The table could have several milions of records or be empty. SELECT count( * ) looks to me as not the best way.
Kind regards

Hi,
One approach is:
check lt_mytable is initial.
This will be true if there are no lines.
Another:
describe table lt_mytable lines lv_count
if lv_count = 0.
"Empty

Moving data between tables (how to find out if the 2nd table is empty)

Hi,
I have 2 tables, and I'm copying records from one table to another.
I've followed the Wiki: [https://www.sdn.sap.com/irj/sdn/wiki?path=/display/vc/movingdatabetween+tables]
So far, everything works ok.
Here is my question: how do I get the number of records passed?
I mean, how do I know the number of rows in the 2nd table? (Remember that this number is variable, because it depends on how many rows I've inserted and deleted on the 2nd table).
I've tried to achieve that using a data store with a numeric field, but I couldn't find the way to increment/decrement the numeric field on data store, and insert/delete the row on table at the same time .
All I want is to find out if the 2nd table is empty or not.
Any ideas to solve this?
Thanks in advance!
Help will be point-rewarded.
Marcelo

Hi Ahmed
thanks for your reply, it was very helpful!! (I've assigned points to you)
However the user can add twice or more times the same row... so the counter doesn't reflect the real number of rows in the 2nd table.
I've partially solved this also using a data store with a parameter called key_list, where I add (I mean, concatenate) the key field for the selected row.
So, if I have a table with 4 rows with key fields "key1", "key2", "key3", the parameter key_list would get "key1;key2;key3".
So far, it's ok. But when I remove a row previosly added.... I can't remove the key from the key_list parameter. (I mean, from 2nd table I choose to remove the "key2" row, but I don't know how also remove the key name from the key_list)
I hope be clearly enough.
Any help will be really appreciated and point-rewarded.
Thanks again.
Best Regards
PS: is there any way of "mark" a row that has been added to the 2nd table? I mean, using (for example) a hidden boolean field named "added", that becomes true when the selected row is added to the 2nd table.

How to find out what the latest update is for something from apple's site?

i've never been able to do this, and has been a recurring problem for many years:
how can you, using apple's web site -- presumably the support or downloads section -- find out what the latest update for/of a certain product is?
without going into the details, the software update app is of no use to me.
for example, i have a airport extreme base station 54 mbps. how do i go about finding out what it's latest software is? do such products not have a web page which has the latest update linked to from it?
why is it so hard, impossible i find, to find out what the latest software is?
any pointers much appreciated. (i'm not particularly looking for the answer to "what't the latest update for a airport extreme base station 54 mbps?" but a general method for finding out the latest update for anything using apple's web site)
thanks very much.

If you use the Advance Search function:
http://search.info.apple.com/
you can filter results to give downloads for the search words airport extreme base station. The return will be in date order from newest to oldest. Yo ucan also designate word pairs of groups to narrow the search.

How to find out all the OKCODEs for a particular screen?

I am working on t-code CL20N and trying to record with t-code SHDB, in the second screen when I press enter it is coming out, but when I run CL20N without SHDB it is going through all the screens perfectly, SHDB is not working for CL20N.
Is there any other way to find out all the OKCODEs for a particular screen/s?

Hi,
First look for any push button or menu item which can take you to the second screen instead of hitting enter directly in tcode CL20N . If any such button exist in the TCode, u can use the same button in SHDB also for moving to the second screen.
Thanks,
