Highlight text not working in multi-thread client-server application plug-in

I'm developing a plugin application for my dissertation research on multi-application environment. I have an application server that communicate with the PDF document via plugin.
The plugin acts as both client and server, depending on the situation.
- Plugin as Server
I have a multi-threaded winsock2 IOCP running to catch client connections and when a client connected, get the data from the client (set of words), and highlight these words in the pdf document.
- Plugin as client
I use 2 procedures, one to collect all the text from PDF and send to the server using tcp win-socket connection and another to collect data from highlight tool and send these text. both these are not threaded.
Here's my question, because I want to listen to multiple client connections, when the plugin is the server, I'm running this procedure in a thread and then wait for clients to connect and use IOCP to serve the client connections. When the client is connected I use the data coming from client to highlight some text in the PDF document. All of these functionalities are already implemented, but when I receive data from client and try to highlight text in the PDF document my application freezes up and stop working. I think this is something to do with the thread. I'm using _beginthreadex to start the server and then another _beginthreadex inside the IOCP worker thread.
I can post the code, but before that let me know if you can see any problem in this situation. What I see from other posts is that acrobat is not multi-threaded.

Thanks a lot for the reply.
I guess I probably need some sort of a notification when the data is received and do a callback to the main thread to run the acrobat API. Is there anyway I can create custom notifications? Something like this,
AVAppRegisterNotification(AVDocDidOpenNSEL, gExtensionID, ASCallbackCreateNotification( AVDocDidOpen, (void *)DocIsOpenedCallback), NULL);
or should I use a custom action listener?

Oraclient9i.dll error in multi threaded delphi server application

I created a multi threaded server application in delphi using oracle9i and indy server components. When I run my application, I am getting an error "oraclient9i.dll" error when executing my SQL statements. I have check communication between my server application and the client application without using oracle and its working fine, its only when I started executing SQL statements when I got this error.
Can anybody help me with this problem or point me to the right direction on how to resolve this issue.
thanks

> I have tried what you suggested. I have created a
seperate TOracleSession on each thread that I create
on the OnConnect event however I am having Problems
using the oraclesession created on the OnExecute
event. Somehow it is still executing the SQL that I
have created on the main form where I first opened an
oraclesession component created on the main form.
It sounds then like the TOracleSession object in the thread is a copy of the one in the main thread/form.
> Do you think that It would work if I create an
instance of the TOracleDatasets and TOracleQuery on
the OnExecute event and also at the same time create
my TOracleSession on this event and continue
processing the data receive from the client server.
I've never used the Indy components for threading. The default TThread class worked just fine for me.
What I used to do is define the session and database objects as privates in my new thread class (let's call it TThreadSQL) - which was subclassed from TThread.
The constructor of this new TThreadSQL class did the following (writing here purely from memory - have not done Delphi for some time now): constructor TThreadSQL.Create( TNSalias, username, password : string );
// constructor is called with the Oracle session connection details
begin
inherited Create; // call the parent class constructor
CreateOracleSession; // call own private method to create an Oracle connection
end;
The CreateOracleSession method would then:
- create a BDE Session (TSession) object
- create a BDE Database (TDatabase) object, using the BDE Oracle native driver and an Oracle TNS alias plus username and password for connection
The destructor would close the connection. The Execute method which is used to fire up the thread, would use a TQuery object (or whatever) to execute a SQL using it owns connection.

Problems with swiping, highlighting text, not working properly

Hello and new to forum as well as new to BB10. I have the Q10 model and really like it alot. However, these swiping techniques or gestures have me puzzled. Sometimes they work, and most times I find myself swiping the hell out of the screeen out of aggravation. Is there any way this can be tested as to working properly since it is a touch activated control?
I really find myself swiping three times, 5 times or more, just to get to the hub. I cannot close out a screen with one swipe. It will not copy test without repeated taps. The circle pointer is hard to get on. I realize my swiping is a new technique to me, but could it be the protective cover that was put on it? Can anyone help me try to fix this very annoying problem as I am not used to repeated attempts at trying to do something so simple as closing a program or moving to another location tab. I sure would appreciate it.
Thanks in advance.

Hello greg30
Welcome to the BlackBerry Support Community Forums.
Sorry to hear you are having issues with your BlackBerry Q10 smartphone navigational gestures. Please view the follow link as it takes you to a "BlackBerry Q10 Gestures Overview".
The screen protector is some cases can effect the gesture input on the BlackBerry Q10 smartphone screen. This is simply due to the increased thickness of the scratch resistant liner on the touch screen.

Why is predictive text not working on my iPhone 5s anymore

Why is predictive text not working on my iphone anymore

Actually, I just found the answer to my issue in this thread: The type correct/predict function for mail and text in iOS 8.0.2 was working fine then suddenly disappeared and reverted to the old style. I've checked all settings that seemed appropriate. How do I restore? I actually liked the new version.
Which says "a thin gray bar with a white dash in the middle of it immediately above the keyboard, you can reopen the suggestions by sliding up with one finger on the white dash."
That did it.
I too have noticed a change, it seems with the new IOS update. My Predictive setting is on, but it seems before it would come up more often in predicting words and also give me a few choices. Now, it's not coming up as much and only providing one 'predictive' word which is not always right. This change is not very useful.

Discoverer Reports does not work in Multi-org Environment after R12 Upgrade

Discoverer Reports does not work in Multi-org Environment after R12 Upgrade. Created a simple report using the below query:
SELECT po_header_id, segment1, type_lookup_code
FROM po_headers
WHERE segment1 = '5000002'
Query works perfectly fine; when i set the ORG_CONTEXT in the database using the command:
EXEC mo_global.set_policy_context('S',129)
But the report doesn't fetch any data when ran from an Org based responsibility. We've ensured that the MO: Operting Unit is set accurately and general Oracle reports (PLSQL Program OR XML Publisher) are working perfectly fine.
===========
I followed the steps provided in Metalink Note: 732826.1 - It works for some responsibilities where the MO: Security Profile is not set; but fails for those responsibilities where the MO: Security Profile is set.
I am looking for specific solution that works irrespective of either the MO: Operating Unit profile is set of not.
Please suggest. Appreciate your response.
Thanks,

Hi Hussein,
Thanks for the quick response.
Yes, I've gone thru both the notes specified below:
Discoverer Workbooks Based On Organization Enabled Views Are Not Populated [ID 1293438.1]
- Tried this option; but this option is messing up a couple of Oracle Standard Functionalities.
- For ex: If i set this profile option; we are not able to create any receipts using Custom Responsibilities.
I am able to create the receipt, when i remove this profile option.
No Data Shows for Reports in Discoverer 10g with Applications Release 12 [ID 1054380.1]
- I see that the products i am running these reports from AR/GL - already exists in these tables.
Anything other options??
Thanks,
Kesava

Hi
Jalil Cracker,
>>when user pres n then it must go to a form but error arises and not working good and threading is not respondin
Could you post the error information? And which line caused this error？
If you want to show Form1, you can use form.show() method
Form1 frm = new Form1();
frm.Show();
In addition, Cosmos is an acronym for C# Open Source Managed Operating System. This is not Microsoft product.If the issue is related to Cosmos, it would be out of our support. Thanks for your understanding. And you need raise an issue at Cosmos site.

Variable Text not working as dynamic header in Crystal report

Dear Experts,
I'm working Crystal report that connected to Query BEX SAP BW trough SAP integration kit,
currently i have case that need report dynamic header using variable text from BEX query, but seem the variable text not working in Crystal reports. the header in Crystal report shown as Desription\technical name, not result from the variable text in Query BEX in SAP.
In https://wiki.sdn.sap.com/wiki/display/BOBJ/Crystal%20Reports%20and%20BW%20query%20elements stated that the "Text variable" with "replacement path" is supported, but i don't know in my query is not working.
i already set in Database -> options-> table and fields -> Show Both, but the text variable still not working.

Bookmarks not working in multi-document PDF application

Why are bookmarks not working in multi-document PDF application when uploaded to the web? We created a multi-document PDF application. All bookmarks and links work on our systems. All work on the customer's system. They do not work when uploaded to the customers website. Their IT department says its an issue of relative vs. absolute addressing. We've created applications like this for years without running into this issue. Can't find anything about it in Acrobat Help. Can anyone help or lead me to help? Thx much, Sandy

Have you tried opening the file in your browser to see if the bookmarks are working? To open the file in your browser you need to do this:
1) Launch your favorite browser;
2) File >> Open >> Select your pdf file

Live Preview Highlight is not working.

I recently downloaded Edge Code to a new work computer and the Live Preview Highlight is not working.
I have Edge Code installed on a personal computer, and it works great. The version I am using was downloaded about 6 months ago so I am not sure if they changed something with the most recent version. When I highlight a section within the html i.e. a table or row, it would highlight those same sections in the preview. However, this is not the case on my new computer.
Anybody know whats up? Is it setting on Chrome that I need to change or is there some update that I am not aware of.

I guess I assumed that you had Chrome setup to auto-update (like I have it). The only way Live Preview will work in a previous version of Edge Code is with an older version of Chrome.
But there are other reason why Live Preview may not work in latest version of Edge Code. Take a look at Live Preview section of Troubleshooting Guide.

Color Highlights does not work for chart

When I set the color coding in the chart, it works fine if I run the crystal report on the same DB that I use to design the report.
Problem occurs if I run the report on another DB. Color Highlights does not work in that case.
I am using JRC to run the reports.
Thanks & Regards,
Amrita

Hi Jehanzeb,
In chart expert there is a tab "Color Highlightsu201D. In this tab one can specify the condition based coloring.
In my case I want to show "RED" color for Unauthorized events andu201D GREEN" color for Authorized Events.
While creating a report suppose I am using a database server "DB-A".I set the color highlights in the chart as I explained. Please be noted that when we click on the color highlights tab it asks for the database login.
To view the report we have our own server and we are using JRC APIs.
Hence I map my report with server and try to view the Report. My Server is connected with database "DB-B" which is different from the database I used to create the report.
This time color Highlight I have specified while creating the report does not work.
I have tried using the "Format Series Riser" option. But the problem with this is that, it does not color the chart conditionally.
I mean if I give GREEN for Authorized and RED for Unauthorized. It gives the green color either to Authorized or Unauthorized which so ever occur first in the chart.
For example:-suppose there is no Authorized Event on date 15-Jan-2009 and I select the date range starting from 15-Jan.In this case Unauthorized event is the first to print on the chart hence this event get the green color though I expect this events to be in RED color.

Force a multi-threaded client to use more than one proxy.

I have a multi-threaded client app. that I'm using to test our proxy throughput. I've run into the same problem I've seen other people run into where the client application threads all get sent via the same proxy (in my case, I have 16 proxies available and configured in the client config.)
Now I've seen threads like this one: Re: How to dynamically connect Extend client to proxy server?
I just wondered, has a solution appeared since that time? I guess Coherence 3.6 and 3.7 have appeared in the interim. I'm on 3.6.1.4.
My "Coherence specific" code is all localised in each thread and nothing is shared, so I guess the behaviour I'm seeing is something to do with the way Coherence initialises it's client classes within the JVM, rather than something it defers until a cache connection is established.
Any solutions to this problem, so I can get my multi-threaded client (where each thread opens a NamedCache connection and then establishes a CQC against it) to use all (or at least more) of the available 16 proxies?
Cheers,
Steve

Urgent: How to : Multi-threaded Client??

Hi,
I have socket connection and was using single client thread untill now. But now requirements need to have multi-threaded client. Can any one pl. help me how to send messages thru' one thread and receive messages thru' another thread using same connection?? I urgently need help on this.
thanx

Create aclasses derived from thread for use by receiving
Pass the socket to that class's constructor
In the receivers thread's run method just in a while loop call read, or readObject, or whatever
Just send in the regular thread.

The problem about multi-thread in java application

i have problem with the multi-thread in java application, i don't know how to stop and restart a thread safely, because the function thread.stop(),thread.suspend() are both deprecated.
now what i can only do is making the thread check a flag(true or false) to determine whether to start or to stop, but i think this thread will always be in the memory and maybe it will lower the performance of the system, as the program i am developping is working under realtime enviorement.
please help me about it. thanks !

hi,
you can stop a thread by exiting it's run()-method which in terms can be done by checking the interrupted-flag:
public void run(){
while(interrupted()){ //if the thread consists of a loop
or
public void run(){
if(interrupted())return;
if(interrupted())return;
or by the use of the return-statement anywhere withing the run-method. Afterwards, that is when the thread is no longer needed, you clear all the references to the specific thread object by setting them to null:
Thread t;
... //working
t.interrupt(); //interrupting
while(t.isAlive()){
Thread.yield(); //wait till thread t has stopped
t=null;
best regards, Michael

Help needed on TCP/IP Multi-port Client-Server

Hi all, I am trying to develop a client-server application to stream some data over a few random port numbers (defined by myself) to stream data over to the TCP server (i.e another computer) in LabVIEW. So far, I have created my application using the NI examples for "Simple Data Client + Server" and it works fine. I also understand that the "TCP Listen" VI is only able to listen for 1 TCP connection only and a way around this is to use queueing idea to receive & process the incoming data.The downside to the idea is that the "base port" (i.e initial port) needs to be the same (on every TCP client) with the TCP Server and it is not fit for the purpose I intended.
Basically on the TCP server side, i need to chart/monitor the data on different port numbers that is being streamed real-time from the one TCP client computer. Is this possible in LabVIEW?
Can anyone (incl. NI gurus) advise and point me in the right direction?

Solved!

Hi
http://zone.ni.com/devzone/cda/epd/p/id/2739 Here you can download that component.But you can also use TCP icons which is available in Data Commmunications>Protocals>TCp for communication and to read and write data use variant to flattened string. I have attached a small example where i will transfer a constant string to the host PC to check the link between client and the server. Hope this helps you.
