Help need for sending object over TCP Connection

I have
ResultSet rs = (ResultSet)connection.getObject(1)
and i have user's connection connected on a port
Currently i am reading while rs.next elements , preparing somestring and i am using socket_connection.send('to_myuser',somestring) to send message
and user receive it like (while input_stream.readLine() != null )
etc .etc.. i am just writing some algorithm which very common.
i want to reduce this recursion on the my server end and once user receive it , and to get all result set retrieved from that end.
my question is , is it possible to send
connection.send('myuser',rs);
and how to read on the other end.
Thanks in advance

Just want to clarify how we can cache it..? I belive
we have to put data somewher in the ArrayList or
something ....which one major taskOf course caching requires that you store it in something.
>
second, you need a very good algorighm to query all
your collections ... i think oracle SQL mechanism is
very nice.... however in your recommended approach i
have to write lots of searching and sorting
alrogrthm... .correct?Generally no. Requests are usually limited to very few parameters and often limited only to one or zero. Thus a user first gets a list of customer names (no parameters for query) and then request the detail about a specific customer (using the customer id which is only one parameter.)
Note that you mentioned large amounts of data. You didn't specify what large meant. However large requests should never be allowed from users (people). They can't use it anyways. Automated processes should be architected to provide for a technological solution with is cost effective.

Help needed for sending email

Hi,
I need to send one mail to sales order representative. I have mail Id.
I am using FM "SO_NEW_DOCUMENT_SEND_API1".
In email in subject line I need to write 'Sales order' & in body I need to write "Sales order created'.
Anybody will suggest me in which parameters I need to pass the above mentioned value so that I can get appropriate mail??

Help Needed for Sending Mail

Hi Friends,
I am Ravi Maheshwari from India. I am working on a project where we have to take the feedback from the customer/visitors. For that i have design the feedback from and where i have specified our server mail address where that feedback should come.
But when I click on send feedback button it opens the MS-Outlook with all the information and ask to send the mail, it is not sending it directly. so what should i do so it will send the mail directly.
Please help me as This page will go live so early.
Thanks in advance.
Regards
Ravi Maheshwari

Well, I guess you will need to provide some script or servlet you can send the HTTP form request to, that then composes an e-mail, connects to a mail server and sends it...
If all you know is HTML, you'll have a huge lot to learn.

Need to send object instances over the network

I found no other way to implement a switch case to cast objects on both sides to solve my problem.
Basically I need to send objects over a network protocol based on XML, the object is sent inside XML
converted in base64, overall encoding of XML is utf-8.
Let's suppose in my network there are 2 peers connected via socket.
I have multiple instances of different types on both peers but I want to keep these instances
synchronized. If something changes on side A, side B must receive that instance and replace
it in the correct place (just one way, from A to B).
When I receive such instance on B I want to cast it to it's proper instance
of it's proper type and I am scratching my head on how could I implement this without some
sort of unique ID table and switch case.
If I had 1 instance per type could it be done easily?
But I need to keep in synch many instances per type.
Is there any dynamic casting that I can trigger based on some type/instanceID information
I could send along the object?

Can I render a Flash frame as a bitmap and send it over TCP/IP?

I want to draw some combination of bitmaps, flash shapes, vectors, text etc and draw them programmatically into my movie using ActionScript, and then get every "rendered" pixel of my movie (at 100% view) into an array that I send to another program over TCP/IP. Can anyone help me here?
The first part of the question is if its possible to render a frame that is a collection of Flash elements as a bitmap? I know that I can iterate through a bitmap and get every pixel using the getPixel method but I'm trying to access the final rendered frame displayed on my screen, including, as I said Flash shapes and text.
The second question is what would be the best way to send this "video frame" over TCP/IP? Would I use an XML socket connection? That is the only way I know how to send data out of Flash over TCP/IP but I don't know if it is the only way - the help page says the data needs to be formatted as XML, which seems unwieldly for this application.
I'm doing this now by using Max/MSP/Jitter to do a screen capture the size and location of my Flash movie and then send out the resulting matrix using a "jit.net.send" object (which lets you send frames of video over TCP/IP), but this is too clumsy for the installation I am building.
Any help would be greatly appreciated!
-bob

Thanks! That was exactly what I was looking for in the first half of the question. And I guess the draw() method works in AS2 as well as AS3. I will test it but from what I understand, I can use a Bitmap as kind of my bottom-level container, then create (in ActionScript) a movie clip that can contain other movie clips or drawing API commands or whatever, animate these various elements then finally draw() them into the bitmap. I see that in AS3 I can even use getPixels or getVector to capture the full "video frame" in one line of code.
Thanks rothrock, for the helpful links. My application is kind of unusual, in that I'm sending "video" data to a proprietary LED controller box for display on a low resolution LED display. I connect to the box over TCP/IP and send it "frames of video" 20 times a second. I got this to work with this other content and software (Max/MSP/Jitter) and I want to see how I could capture all the rendered pixel data in successive frames of Flash animation, format it properly, then send it over TCP/IP to this controller box. Don't really now enough about the various flavors of TCP/IP connections to figure out how to do this in Flash, and I know there are security limitations built in to Flash that have to be worked around. But my movies are small (say 96 pixels by 72 pixels) and I need to send uncompressed data directly to my controller box, so these interesting links showing how to use server-side scripts to create jpgs or pngs are probably not going to help me. I will hopefully find a higher-level programmer than myself to work this out, and I think some of the techniques here will hopefull prove to be helpful.
Thanks again for your help!

Business rule: a combination consists of a maximum of 4 subjects (must contain)
and the user is less relevant to a COMB_NAME(name of combinations) but user need
the subjects contained in combinations
i need the following output

COMB_ID     subjects
383           Biology,Chemistry,Computer Science,Physics
384           Chemistry,Computer Science,Mathematics,Physics
you can use any of the COMBINATION table(either (2) or (3))
and i want to know
1)which design is good in this case
(i think SUB_ID1,SUB_ID2,SUB_ID3,SUB_ID4 is not a
good method to link with same table but if 4 subjects only(and must) comes
detail table is not neccessary )
now i am achieving the result by program-coding in C# after getting the rows from oracle
i am using oracle 9i (also ODP.NET)
i want to know how can i get the result in the stored procedure itsef.
2)how it could be designed in any other way.
any help/suggestion is welcome
thanks for your time --Pradeesh

Well I forgot the table-alias, here now with:
SELECT C.COMB_ID
, C.COMB_NAME
, (SELECT SUB_NAME
FROM SUBJECTS
WHERE SUB_ID = C.SUB_ID1) AS SUBJECT_NAME1
, (SELECT SUB_NAME
FROM SUBJECTS
WHERE SUB_ID = C.SUB_ID2) AS SUBJECT_NAME2
, (SELECT SUB_NAME
FROM SUBJECTS
WHERE SUB_ID = C.SUB_ID3) AS SUBJECT_NAME3
, (SELECT SUB_NAME
FROM SUBJECTS
WHERE SUB_ID = C.SUB_ID4) AS SUBJECT_NAME4
FROM COMBINATION C;
As you need exactly 4 subjects, the columns-solution is just fine I would say.

Color management help needed for adobe CS5 and Epson printer 1400-Prints coming out too dark with re

Color management help needed for adobe CS5 and Epson printer 1400-Prints coming out too dark with reddish cast and loss of detail
System: Windows 7
Adobe CS5
Printer: Epson Stylus Photo 1400
Paper: Inkjet matte presentation paper with slight luster
Installed latest patch for Adobe CS5
Epson driver up to date
After reading solutions online and trying them for my settings for 2 days I am still unable to print what I am seeing on my screen in Adobe CS5. I calibrated my monitor, but am not sure once calibration is saved if I somehow use this setting in Photoshop’s color management.
The files I am printing are photographs of dogs with lots of detail I digitally painted with my Wacom tablet in Photoshop CS5 and then printed with Epson Stylus 1400 on inkjet paper 20lb with slight luster.
My Printed images lose a lot of the detail & come out way to dark with a reddish cast and loss of detail when I used these settings in the printing window:
Color Handling: Photoshop manages color, Color management -ICM, OFF no color adjustment.
When I change to these settings in printer window: Color Handling: Printer manages color. Color management- Color Controls, 1.8 Gamma and choose Epson Standard it prints lighter, but with reddish cast and very little detail and this is the best setting I have used so far.
Based on what I have read on line, I think the issue is mainly to do with what controls are set in the Photoshop Color Settings window and the Epson Printer preferences. I have screen images attached of these windows and would appreciate knowing what you recommend I enter for each choice.
Also I am confused as to what ICM color management system to use with this printer and CS5:
What is the best ICM to use with PS CS5 & the Epson 1400 printer? Should I use the same ICM for both?
Do I embed the ICM I choose into the new files I create?
Do I view all files in the CS5 workspace in this default ICM?
Do I set my monitor setting to the same ICM?
If new file opens in CS5 workspace and it has a different embedded profile than my workspace, do I convert it?
Do I set my printer, Monitor and PS CS5 color settings to the same ICM?
Is using the same ICM for all devices what is called a consistent workflow?
I appreciate any and all advice that can be sent my way on this complicated issue. Thank you in advance for your time and kind help.

It may be possible to figure out by watching a Dr.Brown video on the subject of color printing. Adobe tv
I hope this may help...............

What is the type of cable do i need for a macbook white to connect to a hdmi cable?

what is the type of cable do i need for a macbook white to connect to a hdmi cable? This is quite a problem since macbook white is not in production anymore.

First we need to know which one of the 9 different models of MacBook you have. To see which model you have go to the Apple in the upper left corner and select About This Mac, then click on More Info (and then System Report if you’re running 10.7 Lion or 10.8 Mountain Lion). When System Profiler comes up check the Model Identifier and post it back here.
The Late 2008 model 5,1 Aluminum Unibody and the Late 2009 model 6,1 and Mid 2010 model 7,1 White Unibody have a Mini DisplayPort. The Early 2006 model 1,1 through Early 2008 model 4,1s plus the Early and Mid 2009 model 5,2s have Mini-DVI ports. Each would take a different adapter to connect with the TV.

How to send joystick data over TCP connection

Hi all,
I am a long time Labview discussion forum user for learning, but this is my first time posting a question, I hope somebody can help me!
In the attached VI I am trying to send data from a joystick over a TCP connection. I can send data fine using the TCP examples (in fact the majority of my VI is just a copy of the example). However I am to the point where I do not know how to send all the data necessary (3 axis data, 12 buttons, and the POV data) over TCP. Strings, clusters, and arrays were never my strong suite and converting between them is a nightmare for me.
Basically I am trying to send each axis data (X,Y, and Z), button data (12 buttons), and POV data (the POV data will be calculated to adjust the position of a camera, so the immediate data is not important, I will add functions to add the change in the button movements to write a standing position for two servos [pan and tilt], for which that I will need to send over the TCP connection) over the TCP connection to control various cameras and motors. I don't know if it is posible to send that much data over a TCP connection in one write VI through a string, and also how to separate the string on the other side in order to control the client VI.
Again, the actual TCP communication I get, and can operate fine, just formatting all the data into a string (or whatever is required) so that I can unpack on the other side is the issue here.
Another question I have (not impotant to get the program running just might make it easier on me) is can a TCP server (which sends the data to the client) also recieve data back from the client on the same port ( for example sensor data and digital positions [on,off])? Or do I need to set up two TCP communication loops with the first client acting as the server on a different port than the first, which then sends the data to the original server, which also has a client TCP configuration in another loop? I hope this makes sense...
One final question.....I already have a solution to this but using labview for the entirety of this project would be nice. I use skype to stream 1080p video from a webcam to my computer so I can view live feed. Can labview do this? This would be awesome if so, I am just not sure if the communication protocols in use could support real time (or as close as possible to streaming) for 1080p video.
Thanks all in advance for your help,

Well, you cast the axis info cluster to a string, but then you cast it back to an array of DBL. Thatr's not compatible. You should probably cast it back to an "axis info" cluster of exactly the same type. Go the the other VI and right-click the cluster wire to create a constant. Now move that diagram cluster constant to the other VI and use it as type.
Your default ports don't seem to match. You seem to have client and server roles confused. In the sever you create a listener, but then you start sending packets, even though no connection is established. The connection needs to be initiated by the client.
Your client stops the loop the first time a timeout is encountered. Shouldn't that be more permanent? Also, please retain code clarity and avoid unecessary complexities. For example, replace the "not or" with a plain "or" and change the loop to "stop if true"

You can send as much as you want. The casting to/from string is the same as described above.

The primary function of a "server" is to wait for a connection and then communicate with the client once a conenction is established. An established TCP/IP connection is fully two-way and both sides can send and receive.

The object to be sent:
import java.io.*;
import java.net.*;
import java.util.*;
class sendNode implements Serializable {
String sendMsg;
int typeNode; // -1 no ObjectNode;
// 1 right node, 2 base node, 3 left node;
Object objectNode;

You forgot to reset the OOS. ObjetOutputStream keeps a buffer of objects, so if you write the same object again with changes on it, you must reset the buffer.
out.writeObject(sendNodeObj);
out.flush();
out.reset();

Help needed for MySQL 5 database DSN less connection with Oracle reports

Hi,
I am using Oracle Develper Suite and java (J2EE) for my application. I am using MySql 5 as database tool. I want to use Oracle reports of Oracle Develper suite. I have created some reports by first creating system DSN for MySql database and then connect Oracle reports to that DSN by "jdbc:odbc" connection string provided in Oracle Report developer wizard. This is working fine.
I want to generate reports without creating system DSN (DSN less) so that i can use my application on any computer without creating DSN for Oracle Reports. I am deploying my application on OC4j as "EAR" file.
Help in this regard will be highly appreciated.
Regards.

Using an 8i client, you will need to configure the tnsnames.ora file with appropriate connection information if you are using local naming. If you are using host naming or something like an Oracle Names server to resolve TNS aliases, you can skip the tnsnames.ora configuration. A default installation of the Oracle client, though, will probably be using local naming.
If the tnsnames.ora file is configured, or you have configured an alternate way of resolving TNS aliases, you should be able to use the connection string
DRIVER={Oracle ODBC Driver};DBQ=<<TNS alias>>;UID=system;PWD=managerIf you wanted to move to the 10g client (the 10g Instant Client could be useful here), there are some streamlined naming methods that could be used instead of configuring the tnsnames.ora file.

Help needed for translation of custom objects

Hi All,
We are currently in the process of upgrading from 11i to R12.1.3. We have a lot of custom reports and forms which needs to be translated based on language preference set at user level. The approach we have taken is as follows:
1. Created one unique look up type for each of the custom objects.
2. Each lookup code is mapped to a field of the custom object (report or form).
3. Entered the translation for each of the lookup codes using Globe icon (Translation Form) available on the lookup form.
4. When the user logs into his account, we are filterting out the record specific to user environment language using the condition:
language of fnd_lookup_values = usernev('lang') and getting the translated labels for each of the fields in the custom object.
Now what we would like to understand is if there is any other better way of doing translation based on user preferred language.
We have heard about Oracle Translation Manager (OTM) but not sure how the same can be used in our case. Also we would like to know how Oracle does translation for the languages that are enabled in a particular instance. We would like to know if a similar approach can be followed for custom objects as well.
Thanks & Regards,

We had the arrayList/collections lecture today.
I asked the teacher about sorting objects and he started explaining hashmaps and then he mentioned another thing which we will only be learning next term, I'm sure we must only use what we have learned.
How exactly can this be done. I have asked a few questions in the post already.
ThanksWell, there was probably a gap in the communication. Hash maps (or hash tables, etc.) are instance of Map. Those are used to locate a value by its unique key. Generally, to speed up access, you implement a hashing function (this will be explained hopefully in class). Think of name-value pairs that are stored where the name is unique.
Contrast this with items that are sorted. Any List can be sorted because its elements are ordered. An ArrayList is ordered, generally, by the order you inserted the elements. However, any List can be given its own ordering via Comparable or Comparator. You can't do this with an ordinary Map. The purpose of a Map is speedy access to the name-value pairs, not sorting. The List likewise has different purposes, advantages, disadvantages, etc. List can be sorted.
A Map is generally similar to a Set. A Set is a vanilla collection that guarnatees uniqueness of each element (note, not name-value pairs, but simple elements). There is one concrete class of Map that can be sorted, TreeMap, but I doubt your professor was referring to that. The values or the keys can be returned from the Map and sorted separately, but again, I doubt he was referring to that.
Take a look at the Collections tutorial here on this site or Google one. It is fairly straightforward. Just keep in mind that things (generally) break down into Set, Map and List. There are combinations of these and different flavors (e.g., Queue, LinkedHashMap, etc.) But if you can learn how those three differ, you will go a long way towards understanding collections.
(Oh, and be sure to study up on iterators.)

URGENT HELP NEEDED!!! No data connectivity after a while, weird errors

I am using T-Mobile's regular prepaid web plan and Wi-Fi just fine, no need for BIS, Rich Email, or BBM (SMS and MMS is just fine). All I ever use are apps that SPECIFICALLY state that they work over standard TCP/IP and Wi-Fi. The problem is, after some time, the apps that one worked over regular data connections and MMS don't connect anymore. Even though the apps said that no BIS is needed, they can't access data. Even RIM's own Facebook app, which claims to work over Wi-Fi (and does) loses data connectivity after a day or so without a full reboot. The only thing that works is the BlackBerry Browser, which still connects to the internet. Along with the apps failing to work, MMS messages also can't be sent.
Rebooting the phone by a battery pull or alt-shift-delete allows the apps and MMS to work, which after a day (sometimes even shorter) stops working again.
Here's what I've done so far:
- Checked and made sure that all permissions for data access
- Checked that my APN settings are correct: epc.tmobile.com
- Checked my Wi-Fi router for connectivity
- Called T-Mobile tech support for help, wiped my phone upon their instruction
- Reinstalled my apps and contacts, T-Mobile sent me new service books
Still the SAME THING with apps and MMS not working after a while. I've narrowed it down to entries in the event log that show up as this, which shows up seconds before my apps and MMS stop working:
a net.rim.hrtRT - PUpI - 9/23 17:06:58
a net.rim.hrtRT - EPdp 0x3 - 9/23 17:06:58
a net.rim.tunnel - Clos-blackberry.net - 9/23 17:06:58
a net.rim.hrtRT - CClG 0x2 - 9/23 17:06:58
W net.rim.hrtRT - XMax - 9/23 17:06:58
W net.rim.hrtRT - XBad - 9/23 17:06:58
E net.rim.mdp - TEma - 9/23 17:06:58
W net.rim.mdp - TDtm - 9/23 17:06:58
i net.rim.mdp - TTex - 9/23 17:06:58
Can any experts or developers tell me what these Warnings and Errors mean? I am pretty sure that whatever "net.rim.mdp" and "net.rim.hrtRT" is doing isn't good.

anyone care to help???
Also, on the 18th I wiped my phone again, and three days later (longest time with no mdp error) the same error occurred in the event log, no internet connectivity afterwards on Wi-Fi or Mobile Network...

Something tells me that the tunnels are being blocked, since closing and recreating them does the same thing. Anyone else have this problem???
