DTR state while port init

Hi,
I've remarked that the DTR line is moved while the serial port initialize. As I'd like it to stay in its position during this period, can somebody tell me wether it's possible or if it's built-in the init process?
If it's the case, how to modify this process?
Thank you in advance.

In LV 7.1, it is buried in the property nodes. First open a VISA session with COM1 or whatever (ASRL...). Then look in the Function palette - Instrument I/O - VISA - VISA Advanced - Property Node. Create a property node on the block diagram and wire it to the VISA session. Then click in the property box and select Modem Line Settings - Line DTR State. Change to write. Right click on property and select Create Constant. This will create an enum with the correct values for asserting DTR and such.

DTR State

I am able to bring up the DTR state property node on my simple serial.vi template. I managed to set it to 0 by wiring a 0 numeric constant to one side of it but this approach is not working now. Is there another way of setting DTR state to 0. What is the sequence also? Resource Name- Propert Node- VISA Serial is this correct?

I had a problem like this a while ago when I switched VISA versions on a computer.
I eventually got it to work by wiring a -1 to the DTR line instead of 0. Don't ask me why it worked, it just did. I have asked in the serial forum why this is, but I've never heard a reason.
As far as I know, -1 is simply an unknown (maybe uncontrolled) state whereas 0 forces 0, and 1 forces 1. Perhaps -1 allows other software / hardware to still take control of the DTR line. Your guess is as good as mine though.....
Give it a try.
Hope this helps

How can I define the start bit in Serial Port Init VI?

I don't know if the number of start bits of the Serial Port Init VI match with the serial communications requirements of the device I need to communicate with.
Is there any way of modifying this parameter?

LabVIEW uses the standard WindowsAPI for all of its serial functions. As such, LabVIEW does not support a customizable start bit since the native serial driver does not.

Make both the normal and over states the same color.

Security Problem while porting to 7.0

Hi Shiva,
whats the backend realm being used ? rdbms , custom realm, ldap
If you want to run a older configuration like 6.x you have to boot the server in
"Compatibility Security mode".
Change the logging level to info (from console)a nd check to see if you have
the following message in the log
####<Jul 18, 2002 11:48:20 AM PDT> <Notice> <Security> <columbia>
<examplesServer> <main> <kernel identity> <> <090082> <Security initializing
using realm CompatibilityRealm.>
This way you can verify that you are running in compatibility mode.
While porting from 6.x to 7.0 I
to get into compatibility mode here are the steps I followed
5)Modified the startscript of WLS6.1 server as follows
a)set PATH=C:\bea70\weblogic70\server\bin;%PATH% -->this is to make sure that
the path contains the wlntio.dll file from 7.0 installation
b)set JAVA_HOME=C:\bea70\jdk131_02 --->This is to make sure that the
new jdk131_02 is bein used
c)set CLASSPATH=c:\bea70\weblogic70\server\lib\weblogic.jar;other entries
--->This is to make sure that weblogic.jar from 7.0 is being used
6)After this I restarted the server(Note that this is actually a 7.0 server
which is being booted because of the changes we made to the start script) The
server started automatically in compatibility mode. Once this happens you will
not see this problem
If you still face this problem please post your config.xml

Getting Linker errors while porting InDesign CC plugin code to InDesign CC 2014

Hello,
I am getting following linker errors during porting of plugin code from InDesign CC to InDesign CC 2014

Thanks,

Hello Bartek,
Your answer resolved similar linker errors I faced while porting InDesign plug-ins from CC to CC 2014.
I added the macro - BOOST_SYSTEM_NO_DEPRECATED to the Preprocessor Definitions in VS 2012 SP4 and the build succeeded.
The second option of adding the macros - BOOST_ALL_DYN_LINK;BOOST_REGEX_USE_CPP_LOCALE;BOOST_REGEX_RECURSIVE;BOOST_HAS_ICU=1;BOOST_ FILESYSTEM_VERSION=3;BOOST_CHRONO_HEADER_ONLY;BOOST_SIGNALS_NO_DEPRECATION_WARNING; did not work for me.
Can you explain why this linker error showed up? And how the macro solved it?
Thanks,
Vijayasri

Uploading to Manual Bank Statement while configuring BRS

Hi,
Please help me in uploading the Manual Bank Statement while configuring BRS.
I have entered into ff67 and tried uploading the Bank statement, but it is not entering into the statement screen and giving message "no statement is available".
Your input please..
Regards,
PP

Actually, if your uploading a Manual Bank Statement, and your getting that message, you're probably hitting the enter key before you have created your first bank statement.
Bear in mind that you should first call up tx FBL3N (it's a good idea to print it or have it opened in another session, since you should reconcile according to what has been posted previously).
Hope this will get you going.
The other reply that you got for this question is, I think, intended for Electronic Bank Statements.

Can Dropdown menu item stay on the "roll over" state while the user's mouse is hoving over the sub

Can Dropdown menu item stay on the "roll over" state while the user's mouse is hoving over the parent's sub-menus?
Thanks

Thanks for the response. My main goal here is to get the drop
down menu word "Overview" to remain red once it reaches the frame
"WhoWeAre" or "OurMission" on the main timeline. If I turn the
button inside the movie clip into an MC to do this, the drop down
menu no longer works. Any thoughts on how to get this drop down
menu to do this?

Black screen upon wake from sleep when I change power state while in sleep

Hi,
I'm having this problem where my MacbookPro won't always wake from sleep.
OSX is 10.6.3 and fully updated.
I've done a lot of troubleshooting, and I can now replicate the issue 100%:
1 - Put the MacbookPro to sleep by closing lid
2 - Change power source (from plugged-in to battery or vice versa)
3 - open lid - MacbookPro will wake, but stays at black screen and is unresponsive.
Only if I change power state while sleeping will this issue show. Anyone else experincing this issue, and anygot got a clue on what to do?
regards,
Lasse

I've seen the same issue after upgrading to 10.6.3. I have a one year old MacBook Pro. I would have the screen be black after coming back from sleep or hibernate (tried both).
The workaround I found is to close the lid -almost- all the way and then immediately open it back up again, like I am catching the Mac going back to sleep and then changing my mind. For whatever reason, this has been reliably solving my issue for the last couple weeks reliably.
Only other oddity I noticed is that immediately after upgrading OS X told me that my one year old battery needed to go in for servicing...
Anyway, now all looks right with the world assuming you don't mind a quick close/open cycle.. Lovely...

HI, I'm planning to Purchase Macbook Pro from United States while I'm there but later I will go back to India. Does it come with international warranty or do I have purchase serperately ? Regards, Mohan

Apple's warranty is global. However, some countries have laws which over rides Apple's warranty. To check to see if India is involved read the info in EU-wide Consumer Laws article.

[CS4-Win] Thread problem while porting

I'm porting my plugin from CS3 to CS4 and I get following error while trying to open document:
Thread local data subsystem not initialized for this thread.
BeginPublicThreadBottleneck has not been called. (known leopard nav services problem here)
In CS3 this code works.
I use Windows native threads in my plugin.
Also I've got several warnings with following text:
CTUnicodeTranslator - Calling into single threaded CoolType from a thread - not safe
Can anybody help?

I'm not too familiar with Windows threads, but you need to initialize the TLS, see http://msdn.microsoft.com/en-us/library/ms686991(VS.85).aspx
If you look in the source/public/includes/CTUnicodeTranslator.h, you can see that there are methods for getting an instance of the converter. This may give you problems when using multiple threads, i.e. several threads may access a the same state-based converter simultaneously resulting in in-correct conversions. Strange though, since Adobe is preparing to make InDesign multithreaded.

EJB 3.0 Stateful bean not saving state while Stateless bean is !!!

My Stateless bean is as follow:
package test;
import javax.ejb.Stateless;
@Stateless(mappedName = "StatelessBean")
public class StatelessBean implements StatelessBeanRemote {
     int counter;
     public void increment(){
          System.out.println("Stateless counter value:"+counter);
          counter++;
My Stateful bean is as follow:
package test;
import javax.ejb.Stateful;
@Stateful(mappedName = "StateFulBean")
public class StateFulBean implements StateFulBeanRemote {
     int counter;
     public void increment(){
          System.out.println("Stateful counter value:"+counter);
Client is as follows:
package test;
import java.util.Hashtable;
import javax.naming.Context;
import javax.naming.InitialContext;
public class TestClient {
     public static void main(String[] args) {
          Hashtable hashtable = new Hashtable();
          hashtable.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
          hashtable.put(Context.PROVIDER_URL, "t3://localhost:7001");
          InitialContext ic;
          try {
               ic = new InitialContext(hashtable);
               StateFulBeanRemote stateFulBeanRemote = (StateFulBeanRemote)ic.lookup("StateFulBean#test.StateFulBeanRemote");
               stateFulBeanRemote.increment();
               StatelessBeanRemote statelessBeanRemote = (StatelessBeanRemote)ic.lookup("StatelessBean#test.StatelessBeanRemote");
               statelessBeanRemote.increment();
          } catch (Exception e) {
               e.printStackTrace();
The output i am getting after running the client twice is as follows:
//first time
Stateful counter value:0
Stateless counter value:0
//second time
Stateful counter value:0
Stateless counter value:1
Shouldn't the counter values be incremented in case of Stateful bean and remain the same for Stateless bean. But the output that I am getting is the complete opposite !!!
Can anyone please explain this confusing behavior of stateless and stateful ejb 3.0 beans.

868664 wrote:
Can anyone please explain this confusing behavior of stateless and stateful ejb 3.0 beans.It is very simple: a stateless bean is ASSUMED to be stateless; you cannot keep state in a stateless bean as a contractual rule. That doesn't mean that you will fail to keep state in them at least for a little while, they are still only Java objects. Generally stateless EJBs are pooled, so you may get the same instance each time you use such an EJB, but you may just get another one. It is not dependable and the rules say don't do it - so don't do it.
A stateful bean is tied to a single client, and so can be used by a client to keep state in it. Since You are running the client application twice you are operating with two different clients and so you will get a new stateful bean each time and your code will keep printing 0. However there is also a bug in your code:
public void increment(){
System.out.println("Stateful counter value:"+counter);
}You are not incrementing anything.

Why do we need to be in certian state while doing restore , recovery

This is just for my understanding
To restore control file - Nomount
Control file should not be in use while u restore .. is it all .. there is more to it.
Same with restoring database
Why in mounted state ... any specific reason .
Same with tablespace... what is state you should be in ? and Why ?
