More help with visible and hidden fields

Looking for the script that will let me click a button and then show hidden text fields.
Here's what I want to do:
I have a text field on my form that if another text field is needed, the user clicks the "Add another Case" button and the hidden text field will appear.

Does anyone have any suggestions? Thanks.
Basically, I have several needs on this form:
First, I only want a text field to be visible if the Add New button is selected. Otherwise I need the text field hidden.
Secondly, I have several text fields where I need to allow for multiple entries of the same type of information. Such as Party Information (which consists of name, address, city, state, etc.) There will be more than one party, so I would need the form to record the first information for the party, then the user clicks Add Another Party......which then clears the previous information allowing for the user to enter the next party info, and so on.
I'm sure this is all basic stuff, but as I said, I'm new to this and just need to be set in the right direction. Not sure how to get you the form.
Thanks a bunch

Help with writing and retrieving data from a table field with type "LCHR"

Hi Experts,
I need help with writing and reading data from a database table field which has a type of "LCHR". I have given an example of the original code but don't know what to change it to in order to fix it and still read in the original data that's stored in the LCHR field.
Basically we have two Function modules, one that saves list data to a database table and one that reads in this data. Both Function modules have an identicle table which has an array of fields from type INT4, CHAR, and type P. The INT4 field is the first one.
Incidentally this worked in the 4.7 non-unicode system but is now dumping in the new ECC6 Unicode system.
Thanks in advance,

SAVING THE LIST DATA TO DB
DATA: L_WA(800).
LOOP AT T_TAB into L_WA.
ZDBTAB-DATALEN = STRLEN( L_WA ).
MOVE: L_WA to ZDBTAB-RAWDATA.
ZDBTAB-LINENUM = SY-TABIX.
INSERT ZDBTAB.
READING THE DATA FROM DB

             SEQNR type ZDBTAB-LINENUM,

Select the data.
SELECT linenum rawdata from ZDBTAB into table T_DATA
     WHERE repid = w_repname
     AND rundate = w_rundate
     ORDER BY linenum.
Populate calling Internal Table.
LOOP AT T-DATA.
APPEND T_DATA to T_TAB.
ENDLOOP.

Hi Anuj,
The unicode flag is active.
When I run our report and then to try and save the list data a dump is happening at the following point
LOOP AT T_TAB into L_WA.
As I say, T_TAB consists of different fields and field types whereas L_WA is CHAR 800. The dump mentions UC_OBJECTS_NOT_CONVERTIBLE
When I try to load a saved list the dump is happening at the following point
APPEND T_DATA-RAWDATA to T_TAB.
T_DATA-RAWDATA is type LCHR and T_TAB consists of different fields and field types.
In both examples the dumps mention UC_OBJECTS_NOT_CONVERTIBLE

Problem with wpa and hidden ssid

hi,
I have a powerbook g4 (1,67ghz). i am having trouble connecting to a netgear router mr814 v3 if i use wpa and hidden ssid, i get a message, that the router would not support wpa!
there is no problem with wep and hidden ssid or wpa with no hidden ssid.
is also have no problems with wpa and hidden ssid with an ibook.
the problems occur only with the powerbook with os x 10.3.9 as well as 10.4.2. even after the recent airport update, no change.
thanks for the help,
ben

I would use WPA and broadcast your SSID.
It use to be useful, but closing your Airport or wireless network (sometimes referred to as not broadcasting your SSID) is really no longer a real option when it comes to wireless security.
Unfortunately "Closed" networks, MAC access control lists, and reduction in transmission power are all more "feel good" security rather than real security. All these various approaches are dated and mistakenly lead to overconfidence.
WPA is your friend if you value wireless security.
My recommendation is not to worry about broadcasting your SSID but use WPA. This will be more secure than a closed WEP encrypted network. Closing your network makes it very difficult for neighbouring networks to see which channels are free thus causing potential interference problems.
Another thing to consider is that a closed network is still broadcasting and therefore is detectable (regardless of whether it is broadcasting a SSID). If someone was determined to hack into your network, then not broadcasting your SSID and MAC address access control is not going to stop them.
WPA is virtually uncrackable (only really vunerable to a dictionary attack if a real word is used as a password) and therefore will stop the casual user and the determined hacker.

Help with count and sum query

Hi I am using oracle 10g. Trying to aggregate duplicate count records. I have so far:
SELECT 'ST' LEDGER,
CASE
WHEN c.Category = 'E' THEN 'Headcount Exempt'
ELSE 'Headcount Non-Exempt'
END
ACCOUNTS,
CASE WHEN a.COMPANY = 'ZEE' THEN 'OH' ELSE 'NA' END MARKET,
'MARCH_12' AS PERIOD,
COUNT (a.empl_id) head_count
FROM essbase.employee_pubinfo a
LEFT OUTER JOIN MMS_DIST_COPY b
ON a.cost_ctr = TRIM (b.bu)
INNER JOIN MMS_GL_PAY_GROUPS c
ON a.pay_group = c.group_code
WHERE a.employee_status IN ('A', 'L', 'P', 'S')
AND FISCAL_YEAR = '2012'
AND FISCAL_MONTH = 'MARCH'
GROUP BY a.company,
b.district,
a.cost_ctr,
c.category,
a.fiscal_month,
a.fiscal_year;
which gives me same rows with different head_counts. I am trying to combine the same rows as a total (one record). Do I use a subquery?

Hi,
Whenever you have a problem, please post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) from all tables involved.
Also post the results you want from that data, and an explanation of how you get those results from that data, with specific examples.

I am trying to combine the same rows as a total (one record). Do I use a subquery?Maybe. It's more likely that you need a different GROUP BY clause, since the GROUP BY clause determines how many rows of output there will be. I'll be able to say more after you post the sample data, results, and explanation.
You may want both a sub-query and a different GROUP BY clause. For example:
WITH    got_group_by_columns     AS
     SELECT a.empl_id
     ,     CASE
                    WHEN c.category = 'E'
              THEN 'Headcount Exempt'
                    ELSE 'Headcount Non-Exempt'
            END          AS accounts
     ,      CASE
                    WHEN a.company = 'ZEE'
                    THEN 'OH'
                    ELSE 'NA'
            END          AS market
     FROM              essbase.employee_pubinfo a
     LEFT OUTER JOIN mms_dist_copy             b ON   a.cost_ctr     = TRIM (b.bu)
     INNER JOIN       mms_gl_pay_groups        c ON   a.pay_group      = c.group_code
     WHERE     a.employee_status     IN ('A', 'L', 'P', 'S')
     AND        fiscal_year           = '2012'
     AND        fiscal_month          = 'MARCH'
SELECT    'ST'               AS ledger
,       accounts
,       market
,       'MARCH_12'          AS period
,       COUNT (empl_id)      AS head_count
FROM       got_group_by_columns
GROUP BY accounts
,            market
;But that's just a wild guess.
You said you wanted "Help with count and sum". I see the COUNT, but what do you want with SUM? No doubt this will be clearer after you post the sample data and results.

MS SQL Server 2014: Error inserting into Temp table with index and identity field

In this thread, I mentioned a problem with SQL Server 2014:
SQL Server 2014: Bug with IDENTITY INSERT ON
The question was answered, it is a bug. To keep you informed on this issue, I open this discussion.
Problem:
The code below works perfectly fine on MS SQL Server 2008 R2 and MS SQL Server 2012, but gives an error every second time the proc is executed on MS SQL Server 2014. If I do not define any index on the temp table, the problem disappears. Defining the index
after the insert, does not help.
SET NOCOUNT ON
GO
IF EXISTS (SELECT 1 FROM sys.procedures WHERE name = 'usp_Test') DROP PROC dbo.usp_Test;
GO
CREATE PROC dbo.usp_Test AS
BEGIN
SET NOCOUNT ON
CREATE TABLE #Source(ID integer NOT NULL);
INSERT INTO #Source VALUES (1), (2), (3);
CREATE TABLE #Dest (ID integer IDENTITY(1,1) NOT NULL);
CREATE INDEX #IDX_Dest ON #Dest (ID);
PRINT 'Check if the insert might cause an identity crisis';
SELECT 'Source' AS SourceTable, * FROM #Source;
SELECT 'Destination' AS DestTable, * FROM #Dest;
SET IDENTITY_INSERT #Dest ON;
PRINT 'Do the insert';
INSERT INTO #Dest (ID) SELECT ID FROM #Source;
PRINT 'Insert ready';
SET IDENTITY_INSERT #Dest OFF;
SELECT * FROM #Dest;
DROP TABLE #Source;
DROP TABLE #Dest;
END;
GO
PRINT 'First execution of the proc, everything OK';
EXEC dbo.usp_Test;

PRINT 'Second execution of the proc, the insert fails.';
PRINT 'Removing the index #IDX_Dest causes the error to disappear.';

I remember few issues with scan2ident function, I am not sure if they have fixed it however it appears that this is intoduced to SQL 2014 and we need help from MS to get this resolved as it needs code analysis.
It is not getting simulated for other versions of SQL apart from SQL 2014.
Also to add, interestingly, the value of rax is not visibly changed and it was successfully passed on to rcx, which has a valid value, so something should have changed the value of rax inside call to function using call qword ptr [r10+50h], and looking at this
it appears that it might be a list of functions and we are going at particular offset [50h]. So, bottom line is that the call to function qword ptr [r10+50h], should be changing something in rax, and debugging/analyzing this code might give us some more idea.

Error when communicating with server, and locked fields

Hi there,
I am having a really weird, and annoyingly intermittent, problem.
I'm trying to write a single value to my application via an Input EVDRE, for testing purposes. I've been doing this all morning (admittedly to a different application set but still...) but this time when I "send and refresh", it takes ages before coming back with this error:
"An error has occurred while communicating with the server"
Further more, if I look at the table "dbo.lckFinance" there is now a locked field in the database for this specific category and time. So a user without access to a DBA (or the database, in my case!) would be stuck now - even if the communication problem was solved, they couldn't post anyway.
The application is not part of appshell, we are running BPC version 7.0.112 on SQL Server 2005.
I've looked in the Event Viewer on the server and found nothing untoward there.
Any idea what is happening and how I can avoid this in future? The communication thing is obviously a problem, but I'm just as concerned by the locking.
Please help!
Many thanks,
Jason

Hi Jason,
If you have problems with the network this has to be solved.
I don't think we can have a software working if a cable was unplug ).
We advice our customer to use citrix servers in case if the latency into network is high (more than 200 ms) and of course in case of loosing packages.
But I don't think the problem in your case is related to the network.
It seems in your case it was a problem of send governor.
This can have problem when the cube and dimension are not syncronize or you have an error in one of dimensions.
Also can you check the table sgqueue if you have any record there when nobody is sending data?
If you have records there then you have to delete these records.
Check also tbl"your application"lock if you have records.
Regards
Sorin Radulescu

Help with JLabels and JTextFields

I'm experimenting with JLabels and JTextFields in a basic JFrame. What I am trying to accomplish (without success) is to align a JLabel above and centered on a JTextField. The tutorials are confusing me. Any help would be greatly appreciated. a Sample of code is ...
JLabel myTextLabel = new JLabel("Who's text Field?");
JTextField myTextField = new JTextField("My Text Field");...after reading the tutorial I thought that I needed to assign L&F variables to the JLabel ... i.e.
JLabel myTextLabel = new JLabel("Who's text field?:", JLabel.CENTER, JLabel.TOP); but this results in an error when compiling. (cannot find symbol), so I thought I need to assign the JLabel to the JTextField. i.e.
myTextLabel.setLabelFor(myTextField);Then I get "identifier" expected. So now being completely confused I am here asking "How do I?" :)
Thanks in advance!

Most likely, you need to think a little more about using a layout manager to hlp you along the way. If memory serves, the default layout manager for a JPanel is FlowLayout and that will simply place the components you add to the panel one after another and allow each to adopt it's preferred size.
One way to ensure that the two compoenets were sized equally, would be to use the GridLayout layout manager and create either one row with two columns, or two rows with one column on each. Then add the compoennets to each of the 'cells' so to speak and that should ensure that they are both the same size.
As to making the text centered in each, both the JLabel and JtextField classes have amethod called setHorizontalAlignment(); it can be used to aligh the text as you require.
Simply create an instance of the class;
JLabel aLabel = new JLabel("Some Text");
// Then set the alignment
aLabel.setHorizontalAlignment(SwingConstants.CENTER);Or, do the whole operation i one step
JLabel aLabel = new JLabel("Sone Text", SwingConstants.CENTER);and then add the componenet to the panel once you have set the layout manager.
Remember that the label.textfield will have to be wide enought to make it obvious that the text is centered!

Help with TYPE and LIKE statements

HI guys,
I know this is really novice stuff, but I am a little confused.
Can anyone please explain the exact difference between TYPE and like with the help of a program, to understand it.
What situation would demand the use of each of the LIKE statement, since I can do all these things using the TYPE ?

Hi Akhil,
I summarized the info in SDN posts and SAP Help, to make it easier for you to understand. I also included some code snippets. Hope these prove to be helpful to you.
The following is from SAP Help:
The Additions TYPE and LIKE
The additions TYPE type and LIKE dobj are used in various ABAP statements. The additions can have various meanings, depending on the syntax and context.
·        Definition of local types in a program
·        Declaration of data objects
·        Dynamic creation of data objects
·        Specification of the type of formal parameters in subroutines
·        Specification of the type of formal parameters in methods
·        Specification of the type of field symbols
A known data type can be any of the following:
·        A predefined ABAP type to which you refer using the TYPE addition
·        An existing local data type in the program to which you refer using the TYPE addition
·        The data type of a local data object in the program to which you refer using the LIKE addition
·        A data type in the ABAP Dictionary to which you refer using the TYPE addition. To ensure compatibility with earlier releases, it is still possible to use the LIKE addition to refer to database tables and flat structures in the ABAP Dictionary. However, you should use the TYPE addition in new programs.
The LIKE addition takes its technical attributes from a visible data object. As a rule, you can use LIKE to refer to any object that has been declared using DATA or a similar statement, and is visible in the current context. The data object only has to have been declared. It is irrelevant whether the data object already exists in memory when you make the LIKE reference.
·        In principle, the local data objects in the same program are visible. As with local data types, there is a difference between local data objects in procedures and global data objects. Data objects defined in a procedure obscure other objects with the same name that are declared in the global declarations of the program.
·        You can also refer to the data objects of other visible ABAP programs. These might be, for example, the visible attributes of global classes in class pools. If a global class cl_lobal has a public instance attribute or static attribute attr, you can refer to it as follows in any ABAP program:
DATA dref TYPE REF TO cl_global.
DATA: f1 LIKE cl_global=>attr,
       f2 LIKE dref->attr.
You can access the technical properties of an instance attribute using the class name and a reference variable without first having to create an object. The properties of the attributes of a class are not instance-specific and belong to the static properties of the class.
Example
TYPES: BEGIN OF struct,
         number_1 TYPE i,
         number_2 TYPE p DECIMALS 2,
       END OF struct.
DATA: wa_struct TYPE struct,
       number    LIKE wa_struct-number_2,
       date      LIKE sy-datum,
       time      TYPE t,
       text      TYPE string,
       company   TYPE s_carr_id.
This example declares variables with reference to the internal type STRUCT in the program, a component of an existing data object wa_struct, the predefined data object SY-DATUM, the predefined ABAP type t and STRING, and the data element S_CARR_ID from the ABAP Dictionary.
The following info is from various posts:
--> Type: It is used when userdefined object link with SAP system data type.
Local types mask global types that have the same names. When typing the interface parameters or field symbols, a reference is also possible to generic types ANY, ANY TABLE,INDEX TABLE, TABLE or STANDARD TABLE, SORTED TABLE and HASHED TABLE.
--> Like: It is when data object link with the other data object.
--> TYPE, you assign datatype directly to the data object while declaring.
--> LIKE,you assign the datatype of another object to the declaring data object. The datatype is referenced indirectly.
you can refer to all visible data objects at the ABAP program's positon in question. Only the declaration of the data object must be known. In this case it is totally irrelevant whether the data object already exists physically in
memory during the LIKE reference. Local data objects mask global data objects that have the same name.
--> Type is a keyword used to refer to a data type whereas Like is a keyword used to copy the existing properties of already existing data object.
Types: var1(20) type c.
data: var2 type var1. ( type is used bcoz var1 is defined with TYPES and it
does not occupy any memory spce.
data: var3 like var2. ( like is used here bcoz var2 is defined with DATA
so it does occupy space in memory ).
data: material like mara-matnr. ( like is used here bcoz mara-matnr is stored in memory)
--> Type refers the existing data type
--> Like refers the existing data object

File upload using Struts and hidden field

Hi,
I have seen many examples to upload file using <html:file> tag. But my request is how to upload file using hidden form field and ActionServlet.
I want to upload image without using Browse button options, through hidden field i will set the image file path and will upload to server using ActionForm.
Please help me friends to solve this new issue,
regards,'
dhaya.

That's not possible.
If it was, it would be a huge security hole. What about mailicious websites with hidden field which points to "c:/my documents/passwords.txt" and automatically submits the form using Javascript?
Consider a signed applet instead. If it is unsigned then you'll get a security popup "Do you trust this software?" anyway.

What's the problem you're having ???

Help with encapsulation and a specific case of design

Hello all. I have been playing with Java (my first real language and first OOP language) for a couple months now. Right now I am trying to write my first real application, but I want to design it right and I am smashing my head against the wall with my data structure, specifically with encapsulation.
I go into detail about my app below, but it gets long so for those who don't want to read that far, let me just put these two questions up front:
1) How do principles of encapsulation change when members are complex objects rather than primitives? If the member objects themselves have only primitive members and show good encapsulation, does it make sense to pass a reference to them? Or does good encapsulation demand that I deep-clone all the way to the bottom of my data structure and pass only cloned objects through my top level accessors? Does the analysis change when the structure gets three or four levels deep? Don't DOM structures built of walkable nodes violate basic principles of encapsulation?
2) "Encapsulation" is sometimes used to mean no public members, othertimes to mean no public members AND no setter methods. The reasons for the first are obvious, but why go to the extreme of the latter? More importantly HOW do you go to the extreme of the latter? Would an "updatePrices" method that updates encapsulated member prices based on calculations, taking a single argument of say the time of year be considered a "setter" method that violates the stricter vision of encapsulation?
Even help with just those two questions would be great. For the masochistic, on to my app... The present code is at
http://www.immortalcoil.org/drake/Code.zip
The most basic form of the application is statistics driven flash card software for Japanese Kanji (Chinese characters). For those who do not know, these are ideographic characters that represent concepts rather than sounds. There are a few thousand. In abstract terms, my data structure needs to represent the following.
- There are a bunch of kanji.
   Each kanji is defined by:
   - a single character (the kanji itself); and
   - multiple readings which fall into two categories of "on" and "kun".
      Each reading is defined by:
      - A string of hiragana or katakana (Japanese phoenetic characters); and
      - Statistics that I keep to represent knowledge of that reading/kanji pair.Ideally the structure should be extensible. Later I might want to add statistics associated with the character itself rather than individual readings, for example. Right now I am thinking of building a data structure like so:
- A Vector that holds:
   - custom KanjiEntry objects that each hold
      - a kanji in a primitive char value; and
      - two (on, kun) arrays or Vectors of custom Reading objects that hold
         - the reading in a String; and
         - statistics of some sort, probably in primitive valuesFirst of all, is this approach sensible in the rough outlines?
Now, I need to be able to do the obvious things... save to and load from file, generate tables and views, and edit values. The quesiton of editting values raises the questions I identified above as (1) and (2). Say I want to pull up a reading, quiz the user on it, and update its statistics based on whether the user got it right or wrong. I could do all this through the KanjiEntry object with a setter method that takes a zillion arguments like:
theKanjiEntry.setStatistic(
"on",   // which set of readings
2,      // which element in that array or Vector
"score", // which statistic
98);      // the valueOr I could pass a clone of the Reading object out, work with that, then tell the KanjiEntry to replace the original with my modified clone.
My instincts balk at the first approach, and a little at the second. Doesn't it make more sense to work with a reference to the Reading object? Or is that bad encapsulation?
A second point. When running flash cards, I do not care about the subtlties of the structure, like whether a reading is an on or a kun (although this is important when browsing a table representing the entire structure). All I really care about is kanij/reading pairings. And I should be able to quickly poll the Reading objects to see which ones need quizzing the most, based on their statistics. I was thinking of making a nice neat Hashtable with the keys being the kanji characters in Strings (not the KanjiEntry objects) and the values being the Reading objects. The result would be two indeces to the Reading objects... the basic structure and my ad hoc hashtable for runninq quizzes. Then I would just make sure that they stay in sync in terms of the higher level structure (like if a whole new KanjiEntry got added). Is this bad form, or even downright dangerous?
Apart from good form, the other consideration bouncing around in my head is that if I get all crazy with deep cloning and filling the bottom level guys with instance methods then this puppy is going to get bloated or lag when there are several thousand kanji in memory at once.
Any help would be appreciated.

Usually by better design. Move methods that use the
getters inside the class that actually has the data....
As a basic rule of thumb:
The one who has the data is the one using it. If
another class needs that data, wonder what for and
consider moving that operation away from that class.
Or move from pull to push: instead of A getting
something from B, have B give it to A as a method
call argument.Thanks for the response. I think I see what you are saying.. in my case it is something like this.
Solution 1 (disfavored):
public class kanjiDrill{ // a chunk of Swing GUI or something
     public void runDrill(Vector kanjiEntries){
          KanjiEntry currentKanjiEntry = kanjiEntries.elementAt(0); // except really I will pick one randomly
          char theKanji = currentKanjiEntry.getKanji();
          String theReading = currentKanjiEntry.getReading();
          // build and show a flashcard based on theKanji and theReading
          // use a setter to change currentKanji's data based on whether the user answers correctly;
}Solution 2 (favored):
public class kanjiDrill{ // a chunk of Swing GUI or something
     public void runDrill(Vector kanjiEntries){
          KanjiEntry currentKanjiEntry = kanjiEntries.elementAt(0); // except really I will pick one randomly
          currentKanji.buildAndShowFlashcard(); // method includes updating stats
}I can definitely see the advantages to this, but two potential reasons to think hard about it occur to me right away. First, if this process is carried out to a sufficient extreme the objects that hold my data end up sucking in all the functionality of my program and my objects stop resembling natural concepts.
In your shopping example, say you want to generate price tags for the items. The price tags can be generated with ONLY the raw price, because we do not want the VAT on them. They are simple GIF graphics that have the price printed on a an irregular polygon. Should all that graphics generating code really go into the item objects, or should we just get the price out of the object with a simple getter method and then make the tags?
My second concern is that the more instance methods I put into my bottom level data objects the bigger they get, and I intend to have thousands of these things in memory. Is there a balance to strike at some point?
It's not really a setter. Outsiders are not setting
the items price - it's rather updating its own price
given an argument. This is exactly how it should be,
see my above point. A breach of encapsulation would
be: another object gets the item price, re-calculates
it using a date it knows, and sets the price again.
You can see yourself that pushing the date into the
item's method is much beter than breaching
encapsulation and getting and setting the price.So the point is not "don't allow access to the members" (which after all you are still doing, albeit less directly) so much as "make sure that any functionality implicated in working with the members is handled within the object," right? Take your shopping example. Say we live in a country where there is no VAT and the app will never be used internationally. Then we would resort to a simple setter/getter scheme, right? Or is the answer that if the object really is pure data are almost so, then it should be turned into a standard java.util collection instead of a custom class?
Thanks for the help.
