How to count the total lines of the file (including the file header)

Hi all,
I am working with Idoc to file scenario(FCC).
I need to map one of the field with a recound count ie.., count of the total lines of the file (including the file header).
Eg:Record Count-- mapping area:Total number of records in the file including file header The total line of the file (including the file header).
Can i get a help on this.
Thanks and Regards,
Manoj

Hi !
If there is a tag of your IDOC that occurs the same quantity of times as file lines you have to create in your target file, you could make a Java user defined function in graphical mapping that "caches the entire queue" (use the corresponding option button), that receives as input that field of the IDOC, and returns the "lenght" (.length property value) of that input parameter (it is an array) as output..that should be the file line quantity..you may also add 1 to that count, for the header.
Hope it helps.
Regards,
Matias.

How to count number of lines in a file?

I am using a BufferedReader to read my file, but I like to know how to count the number of lines in a file is there a way to do that in Buffered Reader or do I have to use FileInputLineStream?

Well, if you know how to read one line with a Buffered reader, and you know how to keep reading lines until you run out, then all you have to to is initialize a counter to zero before you start reading, add 1 to it each time you read a line, and then examine its value when you're done.
Try that, and post again if you get stuck.
Just be careful how you construct your loop. "Off by one" errors are a common way to get bitten. It could happen if you count what you think is the last line, but you've actually already counted all the lines and you end up counting one extra for "there are no more lines".

How to count the no of record in grid.

Hi Experts,
I have one database block & this is bolck has contain 4 non database item is there. In database block has contain the id and description is non database block item. While i m querying the data description is shown depends up on ID. It is in grid. How to count the no of record in grid. My code is
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;

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.

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.

How to change the page Header background colour in a Theme

Hello,
I want to know how to change the page header background colour. If you are in the Editor I don't find a property where to change it.
If you are in the Theme Editor in the header bar I want to change stands <b>Theme Editor</b>. This (in my case blue colored bar) I want to change in another color.

Hello Radhika,
thanks for your answer. Where do I find the option for the pageheader in System Administration>Portal Display>Theme Editor ->IView Trays exactly?
The pageheader is a picture, which must be uploaded for the web dynpro. Why should any webdynpro element in the ivew tray. There is no relationship between these two parts.
I have not found any option to change the web dynpro pageheader. Could there any extra theme editor for webdynpro?
Thanks.

How to change the page header?

Hi,
I just installed and started using Plumtree 6.0 a month ago, and we are still in a trial phase for our company's portal.
I want to change the default page header to replace Plumtree logo to my company's logo. I thought I can change it in the style sheet, but I didn't find where to change in the cssmill folder. I found an artical in edocs.bea.com saying I can modify the header by using ALI Publisher, but I don't know what's the right way to do it and faster.
Can someone guide me how to change the page header?
Thank you. (if this is not the correct forum to post the question, please let me know which forum should I go)

Depends on what you want to do. Personally, I'd do a header portlet and not touch the Plumtree/BEA logos. They're likely to be overwritten when the product receives updates.
This may seem like a lot of steps, but really - it goes quickly
** Think through what you want to display. If all you want to do is replace the image, but you wan to keep the overall layout style then you can create a simple replacement header
Step 1 - create a header portlet
=======================
If you're using Publisher...
=====
* Create a new portlet - choose the Header portlet template
* Upload your image / change the header in the rich text editor
If you're not using Publisher
=====
* Personally, static HTML will do just fine - create a folder and html file called something like "mybanner/mybanner.htm" on your remote portlet server
* Plop in an image (you'll want to swipe some adaptive tags for community and page name - can always stick those in later)
* Create a new remote portlet web service that references this HTML page
* Create a portlet from the web service - make sure the type is "header"
Step 2 - turn it on
=======================
* Create a new experience definition (or modify default - I usually create a new one so you can move it between environments)
* In the experience definition's "header / footer" settings area, tell the header to load from the new header portlet you created
* If you created a custom experience definition, modify your experience rules to load this experience defiintion according to whatever parameters you think make sense (just be careful you don't knock out your login page - we usually use security groups to just say "hey - the user is logged in and is, in fact, a member of this portal - that'll still let your login pages load)
Done
May seem like a lot of work, but really it's just a series of simple steps. Advantage here is you can vary things as you see fit and also just feel safe that the next time Plumtree/BEA updates those imageserver files you'll be good to go. From there you can get as fancy schmancy as you like using adaptive tags, etc. Heck - make it a .NET app if you want and do some crazy personalization or something. Embed stock tickers, important news alerts, whatever.
That help at all?
Thanks,
Eric

Dear Vam,
you can easily do that with css, search the source code of the executed web template for the td tag which is around your coloumn header, remember the style sheet class name it is ´displayed as class= in the td tag.
Now you can add this code the beginning of your web template:
