Can someone please tell me on how to modify this code so that I dont have to enter the file name at all?

Hello
can someone please tell me how to modify this code so that I dont have to enter the file path at all? When i give the same file path constants to both the read and write VIs I'm getting an error message.
Attachments:

Yup use the low level File I/O opening the reference once, and closing it once.
As for the path selection you have an unwired input which is the path to use. Programatically set that and you won't be prompted to select a path. Usually this is done with a path constant to a folder, then using the Build Path, to set the file name in that folder.

How to write a code for open new txt file in swing

hai all,
now i do one project in java.that project's GUI is Swing. But i don't known swing (basic).So how to write a code for open new txt file and "Open window " in menu item on swing.that means when i click the "New" on menu that time open a new txt file. open also like that type.
plz give me that code ! very urgent
Advance Thanks !
RSK

Swing Tutorial:
http://java.sun.com/docs/books/tutorial/uiswing/index.html
Since you don't know the basic of swing read the tutorial, it is for your own good because it is useless if we provide you with a code you don't even understand and how it works.
If you want a menu read the tutorial about using menus and for opening a file read using JFileChooser.
note: don't use the word urgent because it implies that your problem is more important than others.

How to write this query to filter combination of few values

Hi,
I have a table CHIMM which is a transaction table and contains information of the vaccines given to a child.
columns are: child_id, vacc_id, vacc_given_dt. I have to query for remaining vaccines.
HEXA is a vaccine_id which is composite vaccine of DPT1,POL1,HBV1 & HIB1 (vaccine ids).
I want to write to query if any of DPT1,POL1,HBV1 & HIB1 given then HEXA should not be displayed in the result.
OR
if HEXA is given then of course any of DPT1,POL1,HBV1 & HIB1 should not be displayed in the result.
How to write this query?
Regards

Hi,
I'm still not sure what the output you want from that sample data is. Do you just want the child_ids, like this
CHILD_ID
       3
       4? If so, here's one way to get them:
WITH     all_vacc_ids     AS
     SELECT     c.child_id
     ,     c.vacc_id          AS child_vacc_id
     ,     v.vacc_id
     ,     COUNT ( CASE
                         WHEN c.vacc_id = 'HEXA'
                   THEN 1
                     END
                )       OVER ( PARTITION BY c.child_id
                                   )    AS hexa_itself
     FROM          vacc   v
     LEFT OUTER JOIN     chimm c     PARTITION BY (c.child_id)
                      ON     c.vacc_id     = v.vacc_id
     WHERE   v.vacc_desc       = 'HEXA'     -- See note below
SELECT       child_id
FROM       all_vacc_ids
WHERE       child_vacc_id     IS NULL
AND       vacc_id     != 'HEXA'
AND       hexa_itself     = 0
GROUP BY child_id
rha2 wrote:there are alot of vaccines, i just put 3 for example. this query gives error: invalid relational operatorAre you saying that the vacc table contains other rows, but those other rows are not needed for this problem? It would be good if you included an example in the sample data. The query above considers only the rows in vacc where vacc_desc='HEXA'. You can have other rows in the vacc table, but they won't affect the output of this query. The query above makes no assumptions about the number of rows that have vacc_desc='HEXA'; it will report all child_ids who are missing any of them, regardless of the number (assuming the child does not have the 'HEXA' vacc_id itself, like child_id=1).
You still haven't said which version of Oracle you're using. The query above will work in Oracle 10 (and higher).

How to write this query ?

how to write this query ?
list the emp name who is working for the highest avg sal department.
I can use row_number over to get correct result. If we don't use this row_number function, just plain sql, how to do it ?
the row_number version is like this
select emp.* from emp ,
select deptno, row_number() over (order by avg(sal) desc) r from emp
group by deptno
)e
where e.r = 1
and emp.deptno = e.deptno

ROW_NUMBER (or its close relative, RANK) is the simplest and most efficient way to solve this problem. Why not do this the right way?
the row_number version is like this
select emp.* from emp ,
select deptno, row_number() over (order by avg(sal) desc) r from emp
group by deptno
)e
where e.r = 1
and emp.deptno = e.deptno
If there happens to be a tie (that is, two or more departments have the same average sal, and it is the highest), then the query above will only arbitrarily treat one of them (no telling which one) as the highest. Change ROW_NUMBER to RANK to get all departments with a claim to having the highest average sal.
You could use the ROWNUM pseudo-column instead of ROW_NUMBER, if all you want to do is avoid ROW_NUMBER.
Without using ROW_NUMBER or RANK, there are lots of ways involving other analytic functions, such as AVG and MAX.
If you really, really don't want to use analytic functions at all, you can do this:
SELECT     *
FROM     scott.emp
WHERE     deptno     IN (
                  SELECT       deptno
                  FROM       scott.emp
                  GROUP BY deptno
                  HAVING       AVG (sal) = (
                                                   SELECT    MAX (AVG (sal))
                                           FROM          scott.emp
                                           GROUP BY deptno

How to write C# code in HTML code?

Hi,
I want that write C# code in script tag in html document. I write this code:
<script>
function AddNewLinkfn()
var LinkName = prompt("Please enter Link Name:", "");
var LinAddress = prompt("Please enter Link Address:", "");
if (LinkName != "" && LinAddress != "" && LinkName != null && LinAddress != null) {
<% string esmelink=%> LinkName <% ,adreselink= %> LinkAddress<%;%>
</script>
but this has error.
I Thanks anyOne that guide me. :)
Good luck!

Hi Bahare,
The <script> tag is used to define a client-side script, such as a JavaScript.
The <script> element either contains scripting statements or it points to an external script file through the src attribute.Common
uses for JavaScript are image manipulation, form validation, and dynamic changes of content.
You should write C# code inside asp.net (C#)(.cs).page. For more infomation,Please check
http://msdn.microsoft.com/en-us/library/vstudio/k33801s3(v=vs.100).aspx
In addition,
This forum is to discuss problems of C# development.
You'll need to post it in
ASP.NET forum for more efficient responses, where you can contact ASP.NET experts.

Hi, I've checked how to use kannada keyboard in Yosemite. But, there are some 'vattu forms' and other grammar in Kannada language that I don't know how to use it. For eg, Preetiya taatanige nimma muddu mommagalu maduva namaskara? How to write this?

Hi, I've checked how to use Kannada keyboard in Yosemite. But, there are some 'vattu forms' and other grammar in Kannada language that I don't know how to use it. I know how to change between the keyboards and can also view keyboard. However, For eg, 'Preetiya taatanige nimma muddu mommagalu maduva namaskara' How to write this? If anybody can answer this, very much appreciated.
Thanks in advance for your reply.

In general, you need to use the "f" (kannada qwerty keyboard) or "d" key (kannada) between letters to make special forms. Also you may need to adjust the typography settings of the font, which is done by doing Format > Font > Show Fonts > Gear Wheel > Typography as shown below. If you can provide screenshots or more detailed info on things you cannot make, I can perhaps help.
It is important to note that MS Word for Mac does not support Indic scripts -- any other app should work OK.
