Sending more than one string from a server to a client in TCP/IP

hi,
i have two VIs where one is the server and the other the client in TCP/IP. I need to send more than 2 strings to the client at the same time.i have used the XML method but then by using XML i cant send any thing else to the client because of the byte sizes. so either i need a new way to send the strings or a new way to send more data. i have attached my VIs to this post if you need to take a look.
thanks,
Rambaldi.

Well, after looking at the code it is very difficult to understand what you are trying to do. Not to be nasty or anything but your code is a mess. Did you know that in both VIs you have an infinite loop? The only way to exit your VIs is to use the Abort button. This is bad since it doesn't allow you to actually perform any type of cleanup. Your wiring is very difficult to follow. You should also avoid using local variables to pass data through your application. If you need to pass data between two parallel processes use queues, notifiers or an action engine. You can get rid of all of the sequence frames that you have. They aren't really doing anything for you and are unnecessary.
As to your particular question I would have to assume that it is simply a result of bad coding that is preventing you from sending more than one string. You have logic in the second loop that appears to be impossible to get to since the conrol used to switch the case statement is placed on a hidden part of the front panel. Take a look at the TCP server example I posted in this thread. The example is on the second page of that thread.
In order to help you I think you need to provide a good description of exactly what you want your server and client to do. You also need to do some code cleanup to make it readable and easier to follow.

where to place the parameters and is there any space is required?

Windows 8.1 MDM not responding to more than one SyncML from MDM server per session

Here is the behaviour i see, which was not expected by Windows 8.1.
1) Device is enrolled
2) Client initiates the connection with the MDM server defined in provisioning XML during enrollment.
3) MDM Server sends some commands as a SyncML response.
4) Client accepts the commands and sends Status and results.
5) Again MDM Server sends some commands as a SyncML response.
6) Client doesn't respond to these commands or not sending any SyncML. Here is the problem that i am referring to.
We are capturing the traffic in fiddler and found that device is not sending the next request where we are expecting the status for these commands.
The same is being repeated in all the requests client initiates. DM Client responds back only for one syncML sent by the MDM server per session.
Is this the expected behaviour with Windows 8.1? Or are we doing something wrong to see this behaviour?
Below is the SyncML for which I am expecting the response from the DM client. (Note: I got the response for the same SyncML in the first connection, but not in the second.)

How do you send more than one document from the pages app on an iPad?

This is entirely frustrating and I have yet to find an answer for this question even though people have been asking it on the internet for over a year!
I am relatively new to apple and I was considering staying with them for my next iphone because of my apps, but after paying for this app and discovering I can't email more than one document "page" at a time? This makes no sense. Please fix this apple, I'd like to say you have replaced my tablet PC for home-office work but now I am reconsidering...

How can i transfer more than one file from server to client

Hi,
our requirement is transfer more than one files from server to client using the
webutil_file_transfer.as_to_client_with_progress.One file transfer is already working in our system.If anybody know the solution please inform
regards
mat

just an idea ...
for this purpose let us put aside security concerns and other potential problems....
-- Get the content of a server directory with Filter and create zip file
1) create a class that implements java.io.FilenameFilter ...
2) define accept() method ...
3) call File.list() with the filter as a parameter. The returned array of strings will have all the names that passed through the accept() filter
4) use java.util.Zip to create ZIP file on the server side
-- I think it is better to create this functionality as a separate Java class, put it in required folder and after it
-- use Forms->Program->"Import Java class" to create pl/sql wrappers, than to create wrappers for all classes and code in pl/sql
5) use webutil to transfer file on the client
6) use Java on client side to unzip transferred file
if you think this is not too complicated, you should try ...

Crystal Report - More than one table from MySql

Hello, I am in need of help big time.
I have am using Visual Studio 2010 and Crystal Report 10.
The problem that I am incounting is that I am unable to retreive data from more than one table from a MySql database. I have been stuck on this for too long and need to hjump the hurdle.
I am using a MySql connection string, a dataset and a crystal report which is based on the dataset.
The main error that I am having is, the browser opens and a form appears saying "The report you requetsed requires further information" With the Server name: DataSetPropertiesDetials, while the User name and Password fields are then enabled.
I am guessing I am missing something in my code.
When I retreive data from one table the report is fine, but when I try to use more than one table it throws the error.

Could you please help me to modify the code to send both file name and data from server. I am pasting my code. Sorry to ask like this but i am struggling a lot in this issue. When you are free please help me.

How can i send more than one signal to DMA FIFO?

Hello,
I'm trying to send more than one signal to DMA FIFO, but i don't know how to do. When i send one signal i don't have problems. I try to use one block DMA FIFO for one signal. For example if i have 3 signal i use · DMA FIFO but whe i want to wath them in a waveform chart the signals have a delay.
How can I do to send more than one signal to DMA FIFO? and if that's no posible, How i can do for syncronizate the 3 signals?
The data type of the signal is FXP <16,10>

Not quite. You need to use the Integer To Fixed Point Cast to change from the integers to your FXP numbers. You can then build them into a cluster to write to the Waveform Chart.

How to return more than one string?

Hi,below is my code:
@WebMethod(operationName = "CheckBooking")
public String CheckBooking(@WebParam(name = "ID")
String ID) {
try {
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con = DriverManager.getConnection("jdbc:odbc:Flight");
// Statement stmt = con.createStatement();
String b="Select Destination, Date from Flight_Booking WHERE BookingID=?";
PreparedStatement ps=con.prepareStatement(b);
ps.setString(1,ID);
ResultSet a = ps.executeQuery();
//Print the data to the console
while(a.next()){
return a.getString(1);
catch( Exception e ) {
e.printStackTrace();
return "a";
Actually, I would like to select Destination and Date from the database, but if I set the return result as string, then only Destination will be return,how can I modify it so that both of the Destination and Date also will be return?As I know, .Net has a return type called Dataset, in Java what should I write?
Actually,I am writing this web services to consume it on a table from .Net,so what is the most suitable to code it so that more than one string can be return?

Create either a list or an array and assign your values to it and return it.

Fetching more than one row from a table after selecting one value from the dropdown

Hi Experts,
How can we fetch more than one row from a table after selecting one value from the dropdown.
The scenario is that I have some entries in the dropdown like below
A               B               C
11256          VID          911256
11256          VID          811256
11256          SONY      11256
The 'B' values are there in the dropdown. I have removed the duplicate entries from the dropdown so now the dropdownlist has only two values.for eg- 'VID' and'SONY'. So now, after selecting 'VID' from the dropdown I should get all the 'C' values. After this the "C' values are to be passed to other methods to fetch some data from other tables.
Request your help on this.
Thanks,
Preeetam Narkhede.

Hi Preetam!
I hope I understand your request proberly, since this is more about Java and less about WebDynpro, but if I'm wrong, just follow up on this.
Supposed you have some collection of your original table data stored in variable "origin". Populate a Hashtable using the values from column "B" (let's assume it's Strings) as keys and an ArrayList of whatever "C" is (let's assume String instances, too) as value (there's a lot of ways to iterate over whatever your datasource is, and since we do not know what your datasource is, maybe you'll have to follow another approach to get b and c vaues,but the principle should remain the same):
// Declare a private variable for your Data at the appropriate place in your code
private Hashtable temp = new Hashtable<String, ArrayList<String>>();
// Then, in the method you use to retrieve backend data and populate the dropdown,
// populate the Hashtable, too
Iterator<TableData> a = origin.iterator();
while (a.hasNext()) {
     TableData current = a.next();
     String b = current.getB();
     String c = current.getC();
     ArrayList<String> values = this.temp.get(b);
     if (values == null) {
          values = new ArrayList<String>();
     values.add(c);
     this.temp.put(b, values);
So after this, you'll have a Hashtable with the B values als keys and collections of C values of this particular B as value:
VID --> (911256, 811256)
SONY --> (11256)
Use
temp.keySet()
to populate your dropdown.
After the user selects an entry from the dropdown (let's say stored in variable selectedB), you will be able to retrieve the collection of c's from your Hashtable
// In the metod you handle the selection event with, get the c value collection
//and use it to select from your other table
ArrayList<String> selectedCs = this.temp.get(selectedB);
// now iterate over the selectedCs items and use each of these
//to continue retrieving whatever data you need...
for (String oneC : selectedCs) {
     // Select Data from backend using oneC in the where-Clause or whatever...
Hope that helps

Sending more than one name value pair via ajaxRequest.add()

Hi all,
I'm implementing AJAX in Oracle Application Express to perform DML operations on a table. I need to send more than one name value pair via the ajaxRequest object. Can someone guide me how to achieve this? Say for example i need to send 2 values(need to send 2 form elements when submit button is clicked) P3_region and P3_scope. i tried the following methods.
Method 1:
======
ajaxRequest.add('P3_region',document.getElementById('P3_region').value);
ajaxRequest.add('P3_scope',document.getElementById('P3_scope').value);
Method 2:
======
ajaxRequest.add('P3_region',document.getElementById('P3_region').value,'P3_scope',document.getElementById('P3_scope').value);
Neither of them is fruitful. Can someone guide me how to achieve this?
Regards,
Balaji Radhakrishnan.

Hi Roel,
The javascript goes like this.
<script language="JavaScript" type="text/javascript">
function getElement1()
document.getElementById('P3_Element1').value = '';
var ajaxRequest = new htmldb_Get(null,&APP_ID.,'APPLICATION_PROCESS=Element1Process',0);
ajaxRequest.add('P3_Element2',document.getElementById('P3_Element2').value);
ajaxRequest.add('P3_Element3',document.getElementById('P3_Element3').value);
ajaxRequest.add('P3_Element4',document.getElementById('P3_Element4').value);
ajaxRequest.add('P3_Element5',document.getElementById('P3_Element5').value);
ajaxRequest.add('P3_Element6',document.getElementById('P3_Element6').value);
ajaxResult = ajaxRequest.get();
if(ajaxResult)
var wsArray = ajaxResult.split("~");
document.getElementById('P3_Element1').value = wsArray[0];
</script>
The application Process goes like this..
declare
v_Element1 VARCHAR2(60);
begin
select distinct Element1 into v_Element1 from TableA where Element2=:P3_Element2 AND Element3=:P3_Element3 AND Element4=:P3_Element4 AND Element5=:P3_Element5 AND Element6=:P3_Element6;
htp.prn(v_Element1);
exception
when others then
v_Element1 := 'Invalid Header Combination';
htp.prn(v_Element1);
end;
The requirement goes like this..
When i give Element2, Element3,Element4,Element5,Element6 as input in the form page the Element1 should get displayed automatically without refreshing the page. But when i use the above javascript and application process i get the Element1 loaded with some html scripts. I call the javascript using onChange() function.

Sending more than one expense type via E-Mail possible?

Hi to all!
Is it possible to send more than one Expense Type via E-Mail to the CfTE system? If yes: How can I create it?
Thanks for an answer!
Andreas

Hi Andreas,
if you add several attachments to an e-mail, the system will create a separate expense for each attachment. One of these expenses will also get the information from the subject line of the e-mail.
Apart from the attachment scenario, there is no option to create several expense based on a single e-mail.

Andreas
