Input and Output Ports Problem

Hi,
I have defined an IView where I defined the Outcome to an OUTPUT Port EMP which sends Employee Number.
And I had defined one more IView where it starts from an Input Port EMP, which takes Employee Number as Input for the RFC Enabled Function Module.
Both these IViews are there in the same page. So in the page level I tried defining a link between these two ports of these IViews. But I was not able to do that.
Why is it happening so?
Is it possible to define a link from OUTPUT PORT of FIRST IVIEW to INPUT PORT of SECOND IVIEW?
Can anyone let us know if this is possible.

Raja Sekhar

Hi Deep,
Well, I am using VC 6.
And We are on EP 6.0 SP14.
And how to check if these .SDA files are deployed into my PORTAL?
Coming to EPCM values of both the PORTS...
com.sap.visualcomposer:epcm
Both have the same value.

I have on;y one audio port can i use it for input and output at the same time?

i have the new macbook pro 13 in and i want to connect aguitar as input and output on an amp but i have only one audio port

You can't use the jack as an input and output simultaneously. The solution is to look for a USB or Firewire interface to get your guitar sound into the computer.

Input and output on same device, producer/consumer structure

Hello interested people,
I have a question about using the same device for both digital inputs
and outputs. I have written a simple program of one while loop
that continuously polls the device, processes, and requests. I
have addressed the device using two DAQmx Asst. and I have attached
them with their error in/out cluster terminals to provide data flow and
eliminate the chance of addressing the devices at the same time (which
produces an error). Now I want to change this program structure
to a producer/consumer loop foundation with state machine.
In this design, I will have the DI in the producer loop and the DO in
the consumer loop, under one of the states. I can't simply
connect the error in/out ports in this configuration, so my question is
how to avoid the error caused by addressing the same device
simultaneously with two different tasks (input and output)? I
have attached two VI's, the "One Loop" vi is the original configuration
(simplified), and the Producer-Consumer vi is a NONSENSICAL program
that simply represents the desired configuration. (I don't need
any comments on the programming of this vi, it is only an example for
illustration of the problem).
I am thinking about bundling the input data and the error cluster, both
from the PXI 6528 DI, into one cluster, queueing that up, and
unbundling the de-queued elements for some kind of data flow between
the producer loop and the "Request" state of the consumer loop.
Is this the right approach, or am I barking up the wrong tree?
Thanks

Hello,
It sounds to me like you really have two modes:
1. user interface actions determine execution
2. user interface is locked, and execution is automated.
I think it would make sense to use the producer consumer for an architecture. Basically you would do the following:
1. program the producer to handle the user interface as you normally would.
2. provide one additional event case in the producer which would be your "automated handling" case. In that case, you could put a state machine which could run until whatever conditions were met to put your program back in "user interface mode".
Keep in mind that you can use custom USER EVENTS to programmatically generate events ie. you can trigger the start of your "automated handling" form anywhere in your code at virtually any time.
I think this would allow you to take advantage of the producer consumer architecture in its intended spirit, while integrating an automated routine.
I hope this helps!

How can I use a different driver for audio input and output?

I did a search of course, and came up with something about an aggregate. I have no idea what this is, how to do it, or if it would even work for me.
What I am trying to do is:
1) Record into Logic Express using my Tascam US-122.
2) Have playback come out of my computer sound system, not the Tascam.
If I go over to the Audio setup window, I can only record when the driver is set to Tascam US-122. Likewise, I can only listen to sound when my Built-In Audio is selected. It gets rather annoying going between the two.
So, would this aggregate thing solve my problem? If so, how do I do it? Thanks for any help!
-allen

Yes it should do what you want.
Go to "Audio Midi Setup", and go to the Audio menu and click "Open Aggregate Device Editor". The interface is pretty simple but if you do get stuck, just use the help function in Audio Midi Setup, as it has a step by step guide.
Then when you return to logic, go to the Preferences>Audio>Drivers section and select Aggregate Device as the new driver rather than either the built in sound or the tascam. Then the inputs and outputs will apply to BOTH devices.

SSIS: How to use one Variable as Input and Output Parameter in an Execute SQL Task

Hello,
i need your help,I'm working on this issue since yesterday and have no idea how to deal with it.
As I already said in the tilte i want to start a stored procedure via a Execute SQL Task which has around 15 prameters. 10 of these should be used as input AND output value.
As an example:
i have three Variable:
var1    int        2
var2    int     100
var3    int     200
the stroed procedure:
   sp_test
     @var1 int
      @var2 int output
      @var3 int output
   AS
   BEGIN
        SET @var2 = @var2 * @var1
        SET @var3 = @var3 + @var1
   END
So in the Execute SQL Task i call the Stored Procedure as follwos:
    Exec sp_test  @var1 = ?, @var2 = ? output, @var3 = ? output
(I use an OLE DB Connection)
The parameter mapping is as follows:
User::Var1        input                   numeric              0                 -1
User::Var2        input/output         numeric              1                 -1
User::Var3        input/output         numeric              2                 -1
Now my problem. If i set  Var2 and Var3 as Input parameter the values are still the same after running the package. If i set them to a output value the are both Null because the procedure doesnt get any values.
I already tried to list them a second time - like
    User::Var2        input                  numeric              1                 -1
    User::Var2        output                 numeric              1                 -1
or i use a new variable
    User::Var2                  input                  numeric              1                 -1
    User::Var2Return        output                 numeric              1                 -1
but i alwas get the error
"Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done."
Has anybody an idea how I can solve this problem?
Thanks a lot.
Kind Regards,
Alice

Hi Alain,
thx for your answer.
I have around 15 procedures called one after the other to calculated and modify my values. Each procedure is responsible for an other but overlapping set of variables. So i thought it would be a good idea to call them one after the other with the needed variables via a execute sql task.
So if i use a result set, how i get my stored procedure to return 10 values? I would have to use a Function instead of a procedure, wouldn't i?
As if i have 15 procedures this would be a lot of work.
But thanks a lot for the idea. I think an other idea would be to create one function which calls all stored procedures and returns all the calculated values as a result set, wouldn't it?.
Kind Regards.

How can I make Apple Earphones be the Input and Output for Audio

I have some older headphones and they aren't compatible with a Mid 2010 (Intel Core i3) 21.5 Inch iMac
Is there some way to make Apple Earphones be the Input and Output for Audio in the iMac
This is a problem for me personally as when I am talking to someone on Skype the iMac picks up the In-built Microphone audio, and yes the headphones I'm using do work straight from the iMac as audio output
Any help is appreciated

you can connect the headset to something like this
http://www.ebay.com/itm/NEW-MaelineA-3-5mm-Female-to-2-Male-Gold-Plated-Headphon e-Mic-Audio-Y-Splitter-/381100440348
and then connect the mic to the input and the headset to the headset port

FINALLY INPUTTING and OUTPUTTING Annotations!

Ok, before everyone thinks that this is a very bad solution, I have to tell that I`m no programmer and my knowledge of PostgreSQL, Ruby or any other language is very poor.
With useful help from Jamie Hodge, fbm and Nicholas Stokes (mainly)
I could manage to write a command for inputting and outputting from Final Cut Server Annotations.
So lets go to the fun part:
INPUTTING:
1- Create a Response called "Annotations IN" (or whatever you want):
a - Reponse Action: "Run an external script or command"
b - Run Script > *Commnad Path: /Library/Application Support/Final Cut Server/Final Cut Server.bundle/Contents/Resources/sbin/fcsvr_run
Command Parameters: psql px pxdb -c "COPY pxtcmdvalue FROM '/FCSRV/annotation-in.txt' USING DELIMITERS '|';"
2 - Create a poll Watcher with name: "Watch for Annotations IN"
a - Enable: true
b - Monitor Address: Chooses a Device (create a new one or use a tmp one) and path to where you`ll going to put a txt file with the annotations.
c - Response List: Choose the Response you created "Annotations IN" in my case.
d - Event Type Filter: Created, Modified
e - Poll Watcher > Listing Frequency: 2 (or any number of seconds you feel like it).
Listing multiple: 2
Wildcard include Filter: *.txt (or any custom extensions you want)
3 - Create a txt file and use this as a template:
{ASSET_ENTITYID}|1527|{TCIN}/(30000,1001)|{TCOUT}/(30000,1001)|{Annotation}|{USE RID}|{DATE}
Where:
{ASSET_ENTITYID} = Is the entityid of your asset. You can find what number it is by issuing:
/Library/Application\ Support/Final\ Cut\ Server/Final\ Cut\ Server.bundle/Contents/Resources/sbin/fcsvr_run psql px pxdb -c "SELECT pxmdvalue.entityid, pxmdvalue.value AS asset_name FROM pxmdvalue INNER JOIN pxentity ON pxentity.entityid = pxmdvalue.entityid WHERE pxmdvalue.fieldid='1543' AND pxentity.address LIKE '/asset/%';"
This will output ALL your assets, so if you know the name or want to parse the name you can use:
/Library/Application\ Support/Final\ Cut\ Server/Final\ Cut\ Server.bundle/Contents/Resources/sbin/fcsvr_run psql px pxdb -c "SELECT pxmdvalue.entityid, pxmdvalue.value AS asset_name FROM pxmdvalue INNER JOIN pxentity ON pxentity.entityid = pxmdvalue.entityid WHERE pxmdvalue.fieldid='1543' AND pxmdvalue.value='ASSETNAME' AND pxentity.address LIKE '/asset/%';"
Where in ASSETNAME you`ll have to put your Asset Name without extension.
{TCIN} and {TCOUT} is, of course, the TC`s points. In the form of: HH:MM:SS;FF
{Annotation} is the commentary.
{USERID} (in my case was 1)
{DATE}: This one is tricky. My example is 2009-03-15 19:31:15.839795-03
So is in the form YYYY-MM-DD HH:MM:SS.????? I really don`t know the rest. Could be milliseconds?
Of course one can write a script to translate everything from a txt file like:
ASSETNAME | TCIN | TCOUT | ANNOTATIONS | USER
But as I`ve said I`m no programmer
Ok.. now the time for the OUTPUT:
The command-line is:
/Library/Application\ Support/Final\ Cut\ Server/Final\ Cut\ Server.bundle/Contents/Resources/sbin/fcsvr_run psql px pxdb -c "SELECT pxmdvalue.value AS Asset_NAME, pxtcmdvalue.value, pxtcmdvalue.begintc, pxtcmdvalue.endtc FROM pxmdvalue INNER JOIN pxtcmdvalue ON pxmdvalue.entityid = pxtcmdvalue.entityid WHERE pxmdvalue.value='ASSETNAME';"
Where ASSETNAME is the Asset name without the extension.
Or issuing the following to OUTPUT ANNOTATIONS from ALL assets:
/Library/Application\ Support/Final\ Cut\ Server/Final\ Cut\ Server.bundle/Contents/Resources/sbin/fcsvr_run psql px pxdb -c "select * from pxtcmdvalue;"
Adding "> /PATHTO_WHERE_IN_WANT/ANNOTATIONSOUTPUT.TXT" at the end will put all output into a txt file.
It`s possible (in theory) to:
1- Create a boolean md field in FCSRV called "EXPORT Annotations" (don`t choose lookup)
2- add or create a md group called "Export Annotations" and add the above md field to it (don`t choose lookup)
3- Add "Export Annotations" md field to Asset Filter md group
4- Make a Response for Running external command. Command path: /Library/Application Support/Final Cut Server/Final Cut Server.bundle/Contents/Resources/sbin/fcsvr_run
Command Parameters: psql px pxdb -c 'SELECT pxmdvalue.value AS Asset_NAME, pxtcmdvalue.value, pxtcmdvalue.begintc, pxtcmdvalue.endtc FROM pxmdvalue INNER JOIN pxtcmdvalue ON pxmdvalue.entityid = pxtcmdvalue.entityid WHERE pxmdvalue.value=[FileName];' > ~/Desktop/ann-out.txt
(I`m having problem with this, it doesn`t work).
5- Make a Subscription that if Export Annotations modified = true, trigger if changed and trigger the Response above.
6- Add exporting annotations md group to Media md set.
In theory it`s possible to modify the FinalCutServerIntegrationSample get and input annotations instead of adding another "comment" field to md group list.
Few!
Ok so please help beautify this out!
This will be very useful for a lot of people.... We know that it`s only a matter of time to FCSVR have this function built-in... but this "time" could be years.
So let`s start ourselves!
Thank you very much!!
Regards!

How to temporally match/save Input and Output Channels's data?

Hello, I have a voltage-input, voltage-output SISO system, and need to indentify its dynamic response (or transfer function) as a reference to a PID control. Without using the system identification toolbox, my goal is to generate/provide a sine sweep input (ranging 1Hz-5kHz for 10sec) to the system and to save the corresponding output response signal as well as the sweep input signal simultaneously.
I got a sample program online and am trying to modify it as attached, but I really need your advices/comments concerning several problems I am facing with:
1) With the below setting, the number of the acquired Input channel samples obtained is 5461, which is smaller than expected (i.e., 10000). What would I be missing in setting parameters?
- H/W: NI-USB-6341 DAQ
- AO: continuous samples with the waveform timing (1k sampling, 10000 samples => 10 sec, slower sampling just for testing purpose)
- AI: continuous samples, samples to read: 30k, rate: 1k
2) I am using flat sequence structure as a way to making the start point of saving AI and AO data same, but wonders if this is a right method or if there is other better approaches. (I had an idea of using an internal clock with "1-sample mode" for sync, but this may not work at the high speed sine sweep like 5kHz, right?)
3) I just want to provide the sine sweep just once to the system and do not require the "reset" functionality implemented in the original sample program. I failed to remove this "reset" part as I did not fully understand the sample code. If I run the attahed, the generated AO signal is periodically provided to the system. Please give me any advice to modify the program as I want.
Thanks for your help and valualble time.

Hi J. Kim,
To begin, you say you want to synchronize your analog input and output so that they start at the exact same time, yes? To achieve tight synchronization, you need to use DAQmx VIs instead of the DAQ Assistant. There's a good overview of DAQmx VIs here. There's also a document that deals specifically with synchronization in DAQmx here. Additionally, if you go to Help>>Find Examples in the LabVIEW example finder, you can see many other examples of acquiring data using DAQmx.
As for your configuration, you have your analog input DAQ assistant wired far before your analog output DAQ assistant in your sequence strucutre, so the dataflow of the program will cause the analog input DAQ Assistant to execute before the output. They cannot be in different sequences if they are executing simoultaneously, and I would not use flat sequences here except to start the two tasks in DAQmx. Where did you find this example?

Multiple inputs and outputs using DAQmx VIs

Hello,
I am fairly new with the LabView programming language. I have a few training books that I have been reading, and I have been following online tutorials and reading the forums. However, I have come to a problem where I don’t see a clear solution. I am using LabView 2009 (9.0f3) and DAQmx VIs.
I am using a NI 9172 chassis PLC, with two 9201 AI cards, 9217 AI RTD card, 9472 DO card, 9263 AO card, and two 9237 AI Bridge cards.
I am reading eight analog inputs with the 9201 cards, two analog RTD inputs with the 9217 card, three digital outputs with the 9472 card, three analog outputs with the 9263, and eight analog inputs with the 9237 cards.
I wrote a simple program to test one digital output task, two of the analog output tasks, and a single analog input task. I put all of them in the same while loop, and it worked perfectly. However, when I add analog input tasks to the same loop, I get an error 200022. So I tested each sensor individually by changing the channel before each run. I searched error 200022 and found that this is because I cannot start another analog input task until the previous one ends. With this said, I don’t know how to acquire an analog voltage in the same task as an analog RTD voltage. Both inputs take different constants in the start task DAQmx icon.
Attached is my test program. It is titled “Test All”. This is the program I used to test the various sensors. I tested the input sensors one at a time, and it worked fine. A few tasks are written just to test functionality, and will be added to later. The data is only displayed on the screen. I will add triggers and data write to disk functions later. This program works now, but if I add more analog inputs, it will generate the 200022 error.
Can someone show me how to correctly write the code for multiple inputs and outputs using DAQmx? All training materials and tutorials I can find all show a single input or single output, not multiples of each. Thanks for looking.

Hi RandyC,
The Knowledge Base article Using Different Types of DAQmx Global Channels in the Same Task goes into a little more depth of what Bryan is talking about, and it also includes some example code to help show what to do.

Input and output audio not working and no startup chime

The audio, both input and output, on my MacBook Pro has stopped working as well as the startup chime. Otherwise the computer starts up and seems to be working normally. Any ideas as to what the problem is and solutions?

Hey, my MacBook Pro has been doing the EXACT same thing off and on for a few weeks now.
I'm just now having time to browse the forums, so I've not even asked about it.
Yesterday it all started working normally - all sounds.
I'll follow this discussion for sure.
There definitely seems to be enough 'Mac-Daddy' Mac Helpers on here to be able to easily resolve this issue.
i.e.: Andreas! Just reading her stuff lets me know she REALLY knows what she's talking about & is able to explain the highly advanced info in terms people actually get!

Simple input and output in a loop

I'm trying to get some user input in a loop. This is a simplification.
import java.util.Scanner;
public class Main {
 public static void main(String[] args) {
 Scanner input = new Scanner(System.in);
 for (int i = 0; i < 3; i++) {
 System.out.println("Enter a string:");
 String myString = input.nextLine();
 System.out.println("output: " + myString);
}In NetBeans, it usually runs fine for a few loops, but eventually (running the program 5 times or so) I get output like this:
run:
Enter a string:
1
output: 1
Enter a string:
output: 2
Enter a string:
2
3
output: 3
BUILD SUCCESSFUL (total time: 9 seconds)It starts writing the prompt before the output and gets all jumbled. The problem is worse if I have more input and output statments in the loop. I thought it might just be a timing issue, but it doesn't matter how fast or slow I enter the information. After a few successive runs, the output always gets out of order. How can I keep in line?

hi!
why dont you try using printf it will give you a better formating capasities.
it work like this.
import java.util.Scanner;
public class Main {
 public static void main(String[] args) {
 Scanner input = new Scanner(System.in);
 for (int i = 0; i < 3; i++) {
 System.out.println("Enter a string:");
 String myString = input.nextLine();
 System.out.printf("output: %s \n" , myString ); // the %s is the place the string will apear
 //and the \n is a escape caracter that creates a new line.
}if you need more help with printf read this:

Sound Input and Output Disappeared

I am considering a purchase of a used Macbook Pro (4,1) from early 2008 with Snow Leopard 10.6.8 installed. When I first tried the machine, the sound input and output were absent. After removing preference files, resetting NVRAM, etc., I finally got them to work. They worked for a few weeks, but recently they disappeared again. This time, my efforts to ressurrect them have been fruitless.
Here is what I have done in an attempt to remedy the situation:
•Delete com.apple.audio.DeviceSettings.plist and com.apple.audio.SystemSettings.plist
•Jiggle a digital headphone jack in the headphone port
•Verifiy Disk and Repair Permissions
•Reset NVRAM
•Reset SMC
I have read online that some people have replaced the AppleHDA.kext file with the one from 10.6.7 - however, every effort I have made to find this file has resulted in failure. I am not able to locate MacOSXupdCombo 10.6.7.pkg anywhere on the web
Any recommendations? I was able to fix this once before - why not now? Thanks for any and all constructive input...

Did you recieve the install disk(s) when you purchase the machine? I would try doing a back up of your data then a fresh install of the OS. Insert the disk into the mac then click restart and hold the c key, ten follow the prompts.
If you wish to take this route, I would try the 10.6.8 combo update first (it should be fine to run it again), then if you wish you may try the 10.6.7 update. Altough I would just do a OS X reinstall and then run software update till you bring it up to date. On disk 2 there should be the AHT (Apple Hardware Test) that you can run by booting the disk holding the D key to check for a hardware fault.
You may also make a Genius bar appointment for a free evaluation, they have more extensive diagnosis tools and would then tell you what your otions would be. (hey it's free)

Java Input and Output streams

I have maybe simple question, but I can`t really understand how to figure out this problem.
I have 2 applications(one on mobile phone J2ME, one on computer J2SE). They commuinicate with Input and Output Streams. Everything is ok, but all communication is in sequence, for example,
from mobile phone:
out.writeUTF("GETIMAGE")
getImage();
form computer:
reply = in.readUTF();
if(reply.equals("GETIMAGE")) sendimage()
But I need to include one simple thing in my applications - when phone rings there is function in MIDlet - pauseApp() and i need to send some signal to Computer when it happens. But how can i catch this signal in J2SE, because mayble phone rings when computer is sending byte array? and then suddnely it receives command "RINGING"....?
Please explain how to correcly solve such problem?
Thanks,
Ervins

Eh?
TCP/IP is not a multiplexed protocol. And why would you need threads or polling to decipher a record-oriented input stream?
Just send your images in packets with a type byte (1=command, 2=image, &c) and a packet length word. At the receiver:
int type = dataInputStream.read();
int length = dataInputStream.readInt();
byte[] buffer = new byte[length];
int count, read = 0;
while ((count = dataInputStream.read(buffer,count,buffer.length)) > 0)
read += count;
// At this point we either have:
// type == -1 || count = -1 => EOF
// or count > 0, type >= 0, and buffer contains the entire packet.
switch (type)
case -1:
// EOF, not shown
break;
case COMMAND: // assuming a manifest constant somewhere
// process incoming command
break;
case IMAGE:
// process or continue to process incoming image
break;
}No threads, no polling, and nuthin' up my sleeve.

Synchronize input and output tasks to start at the same sample point [C++ NI_DAQmx Base]

I'm trying to initiate the analog input and output streams to start reliably at the same sample.

Hi Michael,
First of all, thanks very much for taking the time to investigate this problem! Much appreciated.
You asked for "an actual error code you got and any description that is given". The full output from the program that I posted earlier in this thread is appended to the end of this message. In summary, following the call to...
DAQmxErrorCheck ( DAQmxBaseCfgDigEdgeStartTrig( outputTaskHandle, outputTrigger, DAQmx_Val_Rising ) );
... with ...
char outputTrigger[] = "Dev1/ai/StartTrigger";
...the error message is ...
DAQmxBase Error: Specified route cannot be satisfied, because the hardware does not support it.
You asked "specifically which M series device you are using"? It is the PCIe 6251 (with BNC 2111 connector block). I'm testing and developing on an Intel Mac Pro (dual boot OS X and Windows XP).
You asked for "the location you pulled the code from". Here it is...
http://zone.ni.com/devzone/cda/epd/p/id/879
...specifically from the file "Multi-Function-Synch AI-AO_Fn.c".
I adapted the NI-DAQmx calls to their NI-DAQmx Base equivalents.
Finally, you asked "Is the trigger necessary, or do you just need to know that the measurements are running on the same clock?". I believe that some kind of sychronized trigger is necessary in my situation (correct me if I'm wrong). Timing is crucial. Say I initiate an analog output stream that delivers a voltage command step 5 ms from the onset. I need to record the response (analog input stream) so that its onset is accurately aligned (synchronized) at 5 ms. A typical recording situation would stimulate and record a short data 'sweep', then wait for the (biological) system to recover, then stimulate and record another short sweep, and repeat. I need all the recorded sweeps to align accurately so that they can be averaged and analyzed conveniently.
I definitely do not want my customers to rely on an expensive external TTL pulse generator to initiate and synchronize each 'sweep'. That would effectively eliminate the cost advantage of an NI board, as well as adding unnecessary complexity in setup and use. It would be a show-stopper for me.
It seems perverse, but would it be possible to use a digital output channel connected directly to a digital input chanel to trigger the input and output streams?
Regards,
John.

XiFi and Audigy Take Over Input and Output from Bluetooth Head

I am having trouble with my bluetooth headset when making phone calls in any VoIP application (Skype, Yahoo!). I usually use the headset as the input and output for my VoIP bits so I can move away from my desk, etc... First, it worked under XP with my Audigy no problem. I bought a XiFi and installed the latest drivers and it began stealing my audio. Oddly, it does not do it until the call connection is made (so I hear the ringing in the BT headset and once the call is answered the system reverts to the mic, a Logitech USB, and main speakers, directly plugged to the soundcard).
I decided to put my audigy back in, because I was planning on upgrading to Vista and thought the XiFi may be bad. I did a fresh Vista install with the Audigy and everything worked (i.e. audio for phone calls stayed in my BT headset). I then upgraded from the Microsoft drivers to Creative?s Vista drivers and the problem then happened with the Audigy as well.
This leads me to believe that some sort of regression happened in the latest drivers. Everything else works great, games, movies, etc? but this is a show stopper because I want to use my bluetooth headset. I tried to downgrade to the Microsoft drivers but the card would no longer work. I have tried a driver install only, then added the software, removed that and did a full install. This is with BETA drivers on Vista, but the problem existed in XP as well which were not BETA drivers AFAIK. I have updated to the latest Bluetooth drivers as well with no luck.
I have confirmed this on two of my PCs and a friend of mine is having the same problem (XP, XiFi) so he went and bought a Skype phone which works correctly.
Thanks in advance

thanks for reply..
Please help me out with the entire setp by step procedure that i have to follow in getting the output in variable
i am using to get the emp name from webservices and i am passing empno from form.
