Web Dynpro - How to set and get info from Component Controller

Hi Gurus!!!
Im having some problems getting and setting info in component controller of my Web Dynpro.
I can't see the difference between View Context and Global Context.
How can i create a Global Context Between two views?
Thanks!
Regards.
Polakinho.-

hii
difference between view context and global context is we can use the same component controller for all the views in the same application.but when when we create node in view context then it will be available for that view only not for any other view...so if we want to use the same node for all the views we need to create that view in the component controller.so it will become global for that application.
for using global node you need to map that context in view controller.for that you need to go to that view then click on context tab and drag and drop node from component controller.so it will be available for that view.i hope it helps you.
regards

Web Dynpro: How to set the header of Tabs in a Tabstrip?

Hi all,
I created a tabstrip with 3 tabs. Now I am trying to give proper heading to each of the Tabs but unable to do so because I do not find any property to the Tab(s) for which, I can assign the heading. Only the following 4 Properties are available for a Tab:
ID
enabled
hasContentPadding
visible
I am able to launch the application but it does not show me any text, although the tabs are clickable. Can anyone please tell me how to make headings (or titles/text) appear individually for each of the tags? If there's any code to do it, please tell me what it is.
Thank you.
P.S: Will award points to the most fruitful solution.

hi,

double click on tha tab that u want to give text to it.
enter the name of the text/heading in text field
activate the screen.
hope it helps

Process Class:How to give and get data from an exe file continuously???

hi,,,
I am trying to run an executable file from my program to give it input and read its output....
And i am having problems...
The exe file takes one input and appends to it "1235" (ITS A TEST CASE).
When it is only for a single input , the program rums perfectly.. but when it is within a loop it does not
Pls help
Here is the code for that EXE file. (its in C)
#include<stdio.h>
int main()
char a[10];
int i;
int k=1235;
while(1){
scanf("%s",a);
if(a[0]=='s')
break;
printf("%s%d\n",a,k);
}Note that when i remove the loop here, my code is able to get and give it data.
My JAVA program::
import java.io.*;
public class Main {
public static void main(String[] args) throws IOException {
        try {
      String line;

        System.out.println(input.readLine());
      input.close();
    catch (Exception err) {
      err.printStackTrace();
}PLS HELP

I see a problem in your C code. You're not flushing stdout after you printf and that usually means java is not seeing whats your C program is printing.
removing the loop probably works because stdout is being flushed right before exit.
I used a perl script to test your stuff and found that flushing made the trick
#!/usr/bin/perl
open(OUTFILE,">>./output.txt");
$| = 1;
while (<STDIN>) {
    if (m/.*error.*/) {
        print STDERR $_;
    } else {
        print STDOUT $_;
    print OUTFILE $_;
    if (m/exit/) {
        last;
close(OUTFILE);
exit;notice "$| =1;" that autoflushes in perl (just in case you were wondering where my flush call went)
Enjoy!

Plug the stick and/or card into the appropriate slots on the side of your Air. Do you see icons for the devices appear on the desktop? Click into them to see what files are there.

How do I get the iCloud to save and sync and upload info from both the devices on my account. Right now I can only do one

You must put each device on the Verizon cloud.
Not both lines on one.
Go and set up a my Verizon account for the second line and you will have Verizon cloud service on that line.
Oh the term "icloud" is a trademark of Apple Inc. Verizon is not Apple.
Good Luck

I have the same problem on my IPAD 2. One calender that i cant delete or find any settings for... Its just in the calender app under diffrent calenders. how do i delete it?

Finder issues and Get Info refusing to show the number of files on items on the main hard drive.

I am having finder issues. Mostly on the main hard drive. It takes ages to find things and I get the spinning wheel every time I open a folder.
So I moved all of my files to a external drive. When I had finished transfering I hit get info on the files on the external drive and on the same folder on the main drive. To ensure that it has copied over all the files. Because it was acting up and not copying all the files.
Get Info refuses to show the number of files within the folders on the main hard drive. It hasppily tells me everything on any of the external drives.
I have reset, the imac. I have re indexed 3 times. I have deleted the finder plist files. I have reset finder using terminal commands. I have moved nearly everything off the main hard drive. But nothing is working.
Can anyone offer any suggestions as to what could be causing my finder and get info issues.
Any help wpuld be appreciated.
Running Mountain Lion on a late 2009 Imac

Some of your user files (not system files) have incorrect permissions or are locked. This procedure will unlock those files and reset their ownership, permissions, and access controls to the default. If you've intentionally set special values for those attributes, they will be reverted. In that case, either stop here, or be prepared to recreate the settings if necessary. Do so only after verifying that those settings didn't cause the problem. If none of this is meaningful to you, you don't need to worry about it, but you do need to follow the instructions below.
Back up all data.
Step 1
If you have more than one user, and the one in question is not an administrator, then go to Step 2.
Enter the following command in the Terminal window in the same way as before (triple-click, copy, and paste):
sudo find ~ $TMPDIR.. -exec chflags nouchg,nouappnd,noschg,nosappnd {} + -exec chown $UID {} + -exec chmod +rw {} + -exec chmod -N {} + -type d -exec chmod +x {} + 2>&-
This time you'll be prompted for your login password, which won't be displayed when you type it. Type carefully and then press return. You may get a one-time warning to be careful. If you don’t have a login password, you’ll need to set one before you can run the command. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The command may take several minutes to run, depending on how many files you have. Wait for a new line ending in a dollar sign ($) to appear, then quit Terminal.
Step 2 (optional)
Take this step only if you have trouble with Step 1, if you prefer not to take it, or if it doesn't solve the problem.
Start up in Recovery mode. When the OS X Utilities screen appears, select
Utilities ▹ Terminal
from the menu bar. A Terminal window will open. In that window, type this:
res
Press the tab key. The partial command you typed will automatically be completed to this:
resetpassword
Press return. A Reset Password window will open. You’re not going to reset a password.
Select your startup volume ("Macintosh HD," unless you gave it a different name) if not already selected.
Select your username from the menu labeled Select the user account if not already selected.
Under Reset Home Directory Permissions and ACLs, click the Reset button
Select
 ▹ Restart
from the menu bar.

Web Dynpro ABAP - Select Option and ALV Component Usage

Hi,
I'm new in ABAP Web Dynpro and i was trying to follow the SDN tutorial
Web Dynpro ABAP - Select Option and ALV Component Usage
In this video, we create a new Web Dynpro ABAP component that uses both Select Options and ALV. Developers can learn the basic mechanisms for working with both of these reusable components.
Following the link: https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/media/uuid/39c54fe7-0b01-0010-0eb6-d63ac2bdd637
I implemented and generated the web dynpro with success but when i execute a test i get a dump on select-option definition.
Note
The following error text was processed in the system ECD : Exception condition "TYPE_NOT_FOUND" raised.
The error occurred on the application server ITAWSECCS01D_ECD_00 and in the work process 0 .
The termination type was: RABAX_STATE
The ABAP call stack was:
Method: DESCRIBE_BY_NAME of program CL_ABAP_TYPEDESCR=============CP
I went in debug and the piece of code dumping is:
lt_range_table =
wd_this->m_handler->create_range_table( i_typename = 'S_PROJ' ).
Is there someone who can help me?
Thanks in advance,
Stefano.

Set and get values with vector

I have a class that that querys a db and sets a value of the result to a vector array. Is it possible to set and retrieve that vector array using the set and get methods?
ex:
my class:
sql = "Select ...";
Vector fName = new Vector();
rs = sqlStatement.executeQuery(sql);
if (rs != null) {
while (rs.next()) {
fName.add(rs.getString("fName") + "");
rs.close();
setFName(fName);
how would I set up the set and get methods???
thanks

I am unsure of what you are asking:
A Vector has set and get methods for it, you use indexes of the array to say what element you want to work with.
If you are asking how do you know what elements of the Vector contain which data columns, you have to remember how you put them in.
If you are asking if you can use set to load the Vector: then NO, you have to have elemenets already there to change, use the add method.
If you are asking how to access the elements of the Vector you use an Enumeration:
for(java.util.Enumeration e = v.elements(); e.hasMoreElements();){
s = (java.lang.String) e.nextElement();
vl.add(s.substring(0, 12));
If you are asking something else: please elaborate what you want--my brain may not be very functional this morning.

How do I create a new account and get stuff from the old account to the new account

How do I create a new account and get stuff from the old account to the new account

There are instructions on this page for creating a new account : Set up an Apple ID in iTunes
Or if you don't want to give credit card details : Create an iTunes Store, App Store, or iBooks Store account without a credit card or other payment method
But you won't be able to transfer purchases from your old account to it, all content that you download from the store will remain tied to the account that downloaded it.
