How can I get selection screen values from outside of program?

Hi. all.
Now. I'm developing moritoring systems and I have problems. for getting selection screen values in runtime. Is there any function, methods or structure to know this?
I'd like to get selection screen values while several programs working in runtime and update these values to table to show current system's status and input values for users in real time.
For example.
Now. 3 PGMs are working on systems.
each PGM is ZAAA01, ZAAA02, ZAAA03.
and ZAAA01 needs input parameter P01, ZAAA02 needs input parameter P02, ZAAA03 needs input parameter P03.
In this case, I have to know values of P01, P02 and P03.
The mornitoring systems will show current working status of PGMs(ZAAA01~03)' and these PGMs' input values.
As fas as I know, the structure 'SCREEN' can be used in each PGM for runtime. Is there any SAP system structure or something else for this purpose?
I hope your hopeful repsponse.
Thanks.

Umm..I need to explain more about this.
of course I know SET, GET PARAMETERS.
But I'd like to minimize coding for each PGM level.
I have over hundreds PGMs and I have to develop the PGM(including tables and structures) that mornitor
all of those PGMs on a report in real-time.
This PGM is kind of Process Manager.
First I should know dialogue job PGM and background job that pass parameters using SAP(ABAP) Memory.
And then I have to update those PGMs' input values via screens into tables in real-time.
So, I couldn't use SET,GET PARAMETERS for this PGM.
I want to know methods that can be used for getting information about runtime PGMs' selection screen field values in SAP systems wide.
Please help me some one knows this.

How Can I get multi column values from dynamic search help?

Hi Gurus;
I'm using dynamic search help in my program.
I want to get multi column values from search help. But I dont know solution for this issue.
I'm using F4IF_INT_TABLE_VALUE_REQUEST FM.
How Can I get multi column values from dynamic search help?
Thanks.

Believe it or not, the same FM worked for me in a dynpro. I will try to explain here how it works in custom screen and then you can do your work for other screens or program types. I am not going to write my actual work but will explain in general.
I have 4 fields (FLD1, FLD2, FLD3, FLD4) and i made the search based on FLD2 and when user click on a line (could be any field), then this would bring the line on to the screens.
There are like 3 steps.
You have your value_tab for my fields FLD1, FLD2, FLD3 and FLD4. This is just the data that we pass into the FM. (data: IT_VALTAB type table of ZVAL_TABLE)
Next map the screen fields into an internal table (data: It_dynpfld type table of dselc ). I also have other internal tables defined (just to keep it straight, i will be putting here) data: It_return type standard table of ddshretval.
Next step is to call the function module. Make sure you have values in IT_VALTAB.
call function 'F4IF_INT_TABLE_VALUE_REQUEST'
exporting
        retfield        = 'FLD2'
        value_org       = 'S'
      tables
        value_tab       = It_VALTAB
        return_tab      = It_return
        dynpfld_mapping = It_dynpfld
      exceptions
        parameter_error = 1
        no_values_found = 2
        others          = 3.
    if sy-subrc <> 0.
      message id sy-msgid type sy-msgty number sy-msgno
      with sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
    else.
      perform get_selected_fields tables It_return.
    endif.
The code within the perform GET_SELECTED_FIELDS - We need to map the result fields after user selects it. The code goes like this. This is step is to update the dynpro fields.
I need a internal table as well as a work area here. like,
data: lt_fields type table of dynpread,
        la_fields type dynpread.
field-symbols: <fs_return> type ddshretval.
so fill out LT_FIELDS from the IT_RETURN table
loop at lt_return assigning <fs_return>.
    la_fields-fieldname = <fs_return>-retfield.
    la_fields-fieldvalue = <fs_return>-fieldval.
    append la_fields to lt_fields.
    clear: la_fields.
endloop.
Call the FM to update the dynpro
call function 'DYNP_VALUES_UPDATE'
    exporting
      dyname               = sy-repid
      dynumb               = '1002' "This is my screen number. You could use 1000 for selection screen (hope so)
    tables
      dynpfields           = lt_fields
    exceptions
      invalid_abapworkarea = 1
      invalid_dynprofield = 2
      invalid_dynproname   = 3
      invalid_dynpronummer = 4
      invalid_request      = 5
      no_fielddescription = 6
      undefind_error       = 7
      others               = 8.
if sy-subrc <> 0.
    message id sy-msgid type sy-msgty number sy-msgno
            with sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
endif.

How can i get the all values from the Property file to Hashtable?

how can i get the all values from the Property file to Hashtable?
ok,consider my property file name is pro.PROPERTIES
and it contain
8326=sun developer
4306=sun java developer
3943=java developer
how can i get the all keys & values from the pro.PROPERTIES to hashtable
plz help guys..............

The Properties class is already a subclass of Hashtable. So if you have a Properties object, you already have a Hashtable. So all you need to do is the first part of that:Properties props = new Properties();
InputStream is = new FileInputStream("tivoli.properties");
props.load(is);

How can I get the edited value from the editor in JTable

I have a JTextField added as an editor to a cell in JTable.
I value gets changed when I press enter.
but in actionPerformed of the JTextField when I say
String txtEditorValue = txtEditor.getText();
I am getting the old value. How can I get the edited value? Thanks.

Hi,
I guess, your understanding of how JTable works together with its models is not good enough - for example the method getTableCellEditorComponent(...) of the TableCellEditor interface is used to get the component, that should be used as editing component - its second parameter is a value that should be used to setup the editing component - it is normally not the editing component itself.
JTable uses an underlying TableModel to store the cell values - if you have edited a cell, JTable gets the value of the editing component by itself and stores it in the TableModel using its setValueAt(...) method. To retrieve this data you only need to query the TableModel using row and column of this cell as parameters
say jt is your JTable, and row and column are the row and column of the cell - so to get the value, simply use
Object obj = jt.getModel().getValueAt(row,column);
if you know, that there is a String in this cell use
String str = (String) jt.getModel().getValueAt(row,column);
The editor component is used for the view of the JTable - you only want the data, which is stored in the model - you don't have to deal with the GUI components in this case.

How can I get the cursor value from a waveform graph

Is there a way to get the value of cursor position on the waveform graph so mathematical calculations be performed on those values. We can see the value in cursor legend, but can we extract those values for future calculations in the block diagram somehow.

Right-click on the waveform graph icon. Select Create>Property Node>Cursor>Cursor Position. That spits out a a xy cluster for the current cursor position.
If you have more than one cursor, you can either set up a loop and set the Active Cursor property node (right click the property node and select "Change to Write") or you can pull everything you ever wanted to know about every cursor with the Cursor List property node.

I see some that there are values for preferences in firefox.cs but I am not certain that these are being used as the default values for preferences. prefs.js in user's profile only has the updated values and not the default values.
Any help towards acheiving this programtically is greatly appreciated.
If the default values are stored in a file, kindly let me know the format in which it is stored for me to parse it programatically.

Dear Friend,
Here when you have the callableSattement as ?=proc(?), the first ? is an output parameter. So you should register it as out parameter using registeroutparameter.
Then you can get the value from the outparameter using callablestatement.getXXX().
Try that way.

I don't know much, but I can follow instructions. How can I get my rental movie from my iPhone to my iPad.... And I've rented another movie, now I want to get it from pc to iPad....help be much appreciated...

Did you rent the film directly on the iPhone ? I've never rented films, but from : http://support.apple.com/kb/HT1415 :
You can move the rental between devices as many times as you wish during the rental period. However, the movie can only be played on one device at a time. If you rent a movie on an iPhone, iPad, iPod touch, or Apple TV, it is not transferable to any other device and you must watch it on that device.
If you've rented a film on your computer's iTunes then you should be able to sync it to your iPad from your computer's iTunes via the Movies tab that shows on the right-hand side of iTunes when you've selected the iPad 'device' on its left-hand side

               System.out.println( "hi!! " + e.getSource() );
               // I need to know a title of the button (which was clicked)...
}The output of the code is something like this:
hi! javax.swing.JButton[,140,5,60x25,alignmentX=0.0,alignmentY=0.5,
border=javax.swing.plaf.BorderUIResource$CompoundBorderUIResource@1ebcda2d,
flags=296,maximumSize=,minimumSize=,preferredSize=,defaultIcon=,disabledIcon=,
disabledSelectedIcon=,margin=javax.swing.plaf.InsetsUIResource[top=2,left=14,bottom=2,
right=14],paintBorder=true,paintFocus=true,pressedIcon=,rolloverEnabled=true,
rolloverIcon=,rolloverSelectedIcon=,selectedIcon=,text=first,defaultCapable=true]
I need this: "first" (from this part: "text=first" of the output above).
Does anyone know how can I get the "text" field from the e.getSource() ?

System.out.println( "hi!! " + ( (JButton) e.getSource() ).getText() );I think the problem is solved..If your need is to know the text of the button, yes.
In a real-world application, no.
In a RW application, a typical need is merely to know the "logical role" of the button (i.e., the button that validates the form, regardless of whether its text is "OK" or "Save", "Go",...). Text tends to vary much more than the structure of the UI over time.
In this case you can get the source's name (+getName()+), which will be the name that you've set to the button at UI construction time. Or you can compare the source for equality with either button ( +if evt.getSource()==okButton) {...}+ ).
All in all, I think the best solution is: don't use the same ActionListener for more than one action (+i.e.+ don't add the same ActionListener to all your buttons, which leads to a big if-then-else series in your actionPerformed() ).
Eventually, if you're listening to a single button's actions, whose text change over time (e.g. "pause"/"resume" in a VCR bar), I still think it's a bad idea to rely on the text of the button - instead, this text corresponds to a logical state (resp. playing/paused), it is more maintainable to base your logic on the state - which is more resilient to the evolutions of the UI (e.g. if you happen to use 2 toggle buttons instead of one single play/pause button).
