How to count the no of fields returned by recordset?

hi friends,
how can i know how many columns have been returned by the recordset

thanx in advance,

ResultSetMetaData rsmd = rs.getMetaData();
int columnCount = rsmd.getColumnCount();ResultSetMetaData will provide you with a great deal of information about the ResultSet - check out the API here: http://java.sun.com/j2se/1.4.1/docs/api/java/sql/ResultSetMetaData.html

Urgent help: How to remove the accumaltion when show movies step by step with buttons

I want to show the movie step by step by clicking the next
button. Inside each frame, many movie clips are generated
dynamically at runtime, and they can be played interactively.
I achieves the step-by-step display of those frames by adding
another layer with the action stop(). But I got one trouble: all
the movie clips from previous frames are accumalted. How to remove
the accumulation from previous frames?
For the continuous display of the movie, I tried to use
onEnterFrame() and change the _visible property of all the movie
clips to false in this function. But it doesn't work for the
step-by-step display. Once I click the next button, the movie clips
at the current frame just show very quickly, then disappear. What
should I do?
I need to fix this immediately.
Your help would be greatly appreciated.
- zcx

you can use the removeMovieClip() method for those movieclips
added dynamically.

Urgent HELP - How to reduce the number of entries in table MESYBODY?

Does anyone know how to reduce the number of records in synchronization table MESYBODY and MESYHEAD? The reason I wanted to reduce these tables is because I believe they have so many duplicated entries that causes extremely slow performance everytime we sync. Currently, there are almost 50,000 records for approximately 100 users, and I believe it shouldn't be that much.
We are running into a problem that it takes approximately 25-30 minutes to sync.
Any advices would be highly appreciated.
Regards,
Dai

Hi Dai,
please try to run the middleware job WAF_MW_MAPPING. For some applications (Mobile Time and Travel for example) this helps to clean the tables.

Hi Nine,
To hide select options you should use interface method REMOVE_SELECTION_SCREEN_ITEM of IF_WD_SELECT_OPTIONS.
Sample code :
Write the below code in the Event handler of Radio Button.
DATA lv_r_helper_class TYPE REF TO if_wd_select_options.
lv_r_helper_class = lo_interfacecontroller->init_selection_screen(
lv_r_helper_Class->REMOVE_SELECTION_SCREEN_ITEM(exporting i_id = 'Select_option1_id1').
This will hide first select option of your screen.Similarly pass select_option_id2 to hide it and so on.

How to count the number of AAA clients

Hi,
As we know, ACS5.2 is required with a base license-- supporting 500 network devices.
Sometimes there are lots of AAA clients or network devices that are authenticating simultanious. So my question is, how to count the network devices allowed to auth on ACS5.2? Does that only include network devices, or including both any network devices or AAA clients?
Rgds,
Laowu5017

Hi,
ACS 5.x counts the number of AAA clients that are configured on the ACS.
Please note that AAA clients and networks devices is the same and they comply switches, routers, WLCs, or whatever other device configured under
Network Resources >
... >
Network Devices and AAA Clients
AAA Clients are NOT the AAA suplicants.
The end user clients PCs are the AAA suplicants, and for this there is no limit number.

LV_CUR_ITM :=:SYSTEM.CURSOR_RECORD;
FOR I IN 1.. LV_CUR_ITM LOOP
LAST_RECORD;
SELECT NSN_NO INTO :ORD_DIS_NSN_ITEM_DET.NSN_NO
FROM NSN_MST WHERE NSN_ID= :ORD_DIS_NSN_ITEM_DET.NSN_ID;
SELECT FOB_PRICE INTO :ORD_DIS_NSN_ITEM_DET.FOB_PRICE

NEXT_record;
END LOOP;
Thx in advance.

Hai,
Add a Non database item to that block, and set the Calculation Mode as Summary, and Summary Function to Count.
Then u will get the total no of records from this text. ( You can hide this, so that the use won't see it. )
OR
go to the Last Record, then
LV_CUR_ITM :=:SYSTEM.CURSOR_RECORD; This will also work.

Manu.

How to count the number of rows in a resultser object?

hi there
how to count the number of rows in a resultser object which may contains millions of rows? besides using a while loop? thanks

You don't, you execute a query whose result is the record count of those records that match the search and then you execute the actual query to create your record set. Typically you do
select count(id) from YourTable where [filter]
from the resulting ResultSet do
int res.getInt(1);
which gives you the count and then
select id from YourTable where [filter]
to produce the actual result set.
in the second query the id part can be substituted with the actual fields you want.

Programming help - how to get the read-only state of PDF file is windows explorer preview is ON?

Programming help - how to get the read-only state of PDF file is windows explorer preview is ON?
I'm developing an application where a file is need to be saved as pdf. But, if there is already a pdf file with same name in the specified directory, I wish to overwrite it. And in the overwrite case, read-only files should not be overwritten. If the duplicate(old) file is opened in windows (Win7) explorer preview, it is write protected. So, it should not be overwritten. I tried to get the '
FILE_ATTRIBUTE_READONLY' using MS API 'GetFileAttributes', but it didn't succeed. How Adobe marks the file as read-only for preview? Do I need to check some other attribute of the file?
Thanks!

Qtn: I have 10 standard elementary search helps in collective standard search help, how to deactivate the 10th elementary search help?

Qtn: I have 10 standard elementary search helps in collective standard search help, how to deactivate the 10th elementary search help?

Hello,
this topic is still a problem for me, does anybody have an idea.
Just to show what's my problem:
Collective Search help KRED does include a SAP append-search help ASH_KRED which holds the elementary search helps KREDC, KREDE, KREDM, KREDW.
The search helps KREDE, KREDM, KREDW should not be displayed, so I added another Serach-Help-Append ZKRED_CUST at the end of CSH KRED which holds these 3 SH's with the hidden flag.
That works, the SH's are not shown anymore.
I also added some other of the Original SAP SH's (e.g. KREDA) with the hidden flag and added changed copies of these (e.g ZKREDA) there to be shown instead.
All this can be done modification free by appends.
The folders of the elementary search helps are shown in the order as they are found included in the KRED SH and the append to this SH.
This means that the not hidden Sh KREDC from ASH_KRED is shown before all the "custimized" ZKREDx -SH's. But we need this SH not very often, so that I want it to displayed al the right-most position of the folders of SH's or at the most down postition of the drop-down-selection of SH's.
But I have not found any way to do this modification free.
The only way to archive this is to modify ASH_KRED by setting the Hidden-Flag for KREDC and add this SH at the end of append-SH ZKRED_CUST again.
But I want avoid this modification.
So, is there any way to do this without modifing any of the original SAP SH's ?

How to count the number of wins?

I have a tic tac toe simulator that simulates a game of tic tac toe (obviously). I press the 'play' button, and 1 random X and O is placed in 9 of the labels. Then the application says if X or O wins, or if the game was a tie/no winner. So,
what I want to do is when I click the 'exit' button, I want a message box telling the user how many times X won, O won, and how many ties there were. I am not too sure how to count the number of wins.
-Thanks

Thanks for the reply. I could be wrong, but I do not think that is exactly what I am looking for. Here is the code that I have that determines the winner:
switch (checkWinner())
case 'T':
winnerLabel.Text = "It was a tie!";
break;
case 'O':
winnerLabel.Text = "O Wins!";
break;
case 'X':
winnerLabel.Text = "X Wins!";
break;
private char checkWinner()
char WinnerChar = ' ';
int winning_line = 0;
if (GameBoardCellChar[0].Equals(GameBoardCellChar[1]) && GameBoardCellChar[0].Equals(GameBoardCellChar[2]))
WinnerChar = GameBoardCellChar[0];
winning_line++;
if (GameBoardCellChar[3].Equals(GameBoardCellChar[4]) && GameBoardCellChar[3].Equals(GameBoardCellChar[5]))
WinnerChar = GameBoardCellChar[3];
winning_line++;
if (GameBoardCellChar[6].Equals(GameBoardCellChar[7]) && GameBoardCellChar[6].Equals(GameBoardCellChar[8]))
WinnerChar = GameBoardCellChar[6];
winning_line++;
if (GameBoardCellChar[0].Equals(GameBoardCellChar[3]) && GameBoardCellChar[0].Equals(GameBoardCellChar[6]))
WinnerChar = GameBoardCellChar[0];
winning_line++;
if (GameBoardCellChar[1].Equals(GameBoardCellChar[4]) && GameBoardCellChar[1].Equals(GameBoardCellChar[7]))
WinnerChar = GameBoardCellChar[1];
winning_line++;
if (GameBoardCellChar[2].Equals(GameBoardCellChar[5]) && GameBoardCellChar[2].Equals(GameBoardCellChar[8]))
WinnerChar = GameBoardCellChar[2];
winning_line++;
if (GameBoardCellChar[0].Equals(GameBoardCellChar[4]) && GameBoardCellChar[0].Equals(GameBoardCellChar[8]))
WinnerChar = GameBoardCellChar[0];
winning_line++;
if (GameBoardCellChar[2].Equals(GameBoardCellChar[4]) && GameBoardCellChar[2].Equals(GameBoardCellChar[6]))
WinnerChar = GameBoardCellChar[2];
winning_line++;
if (winning_line == 0 || winning_line > 1)
WinnerChar = 'T';
return WinnerChar;
Do I have to include something extra in here to get the count or no?
The code I posted is the coding in my play button.
