Hi Guru's I need this Codes
Hi all,
im new in this SQL type Commands. benn studying this for almost 2 weeks. if you can help me with this...
i would like to know how to ADD, EDIT, SEARCH using SQL codes with the follwing...
i have 4 fields in my DB namely (RegNo, Lastname, Firstname, MI)
*** i know how to insert this but the problem is i dont know how to check wether the DB contains the following names already. it keep on saying in the err function that cant "cant perform due to DB is closed"
i would like to know how to insert using INSERT TO function that checks wether the DB contains the 4 field name already...
another one is in searching
i can search the DB but it wont display wether the record exist or dont.. then the form dont display the specific field names on the textboxes..
best regards and thanks a lot
i would like to know how to ADD, EDIT, SEARCH using
SQL codes with the follwing...ADD ... INSERT INTO <Table> VALUES (<Values>)
EDIT ... UPDATE <Table> SET <Field> = <Value> WHERE <Condition>
SEARCH ... SELECT * FROM <Table> WHERE <Condition>
i have 4 fields in my DB namely (RegNo, Lastname,
Firstname, MI)
*** i know how to insert this but the problem is i
dont know how to check wether the DB contains the
following names already. it keep on saying in the err
function that cant "cant perform due to DB is
closed"DB closed seems to be caused by a different problem. If you can connect to your database, you should be able to use the commands mentioned above.
i would like to know how to insert using INSERT TO
function that checks wether the DB contains the 4
field name already...If you want to check if the table and its fields already exist, you can use the following views:
SELECT * FROM user_tables;
SELECT * FROM user_tab_columns;
Just add the conditions to look for your table/columns.
another one is in searching
i can search the DB but it wont display wether the
record exist or dont.. then the form dont display the
specific field names on the textboxes..You could use
SELECT Count(*)
FROM <TABLE>
WHERE <Condition>;Since I don't know which environment you are refering to (form/textboxes) I could only guess ... Maybe you want to have a look at the documentation on the product(s)?

Return Current month Data:Help needed in modifying this code of a Procedure
Hello Folks i have this scenario where i need to modify this code so that it has to return data from the Current month First Day to the previous Day if its a daily report and previous month data if its a monthly report.
I have no clue how to modify this code below. Currently the code is returning data for Monthly reports for the previous month. Does anyone have any idea how to modify so that the code meets the requirements of both daily and monthly reprts.
BEGIN
if v_lowdate is null or v_highdate is null then
select to_number(to_char(sysdate, 'DD')) into v_cur_day from dual;
if v_cur_day < 25 then
-- this is for the previous month run
Select Add_Months(trunc(sysdate, 'MONTH'), -1)
INTO V_LOWDATE
FROM DUAL;
SELECT Last_Day(ADD_Months(Sysdate, -1)) INTO V_Highdate From Dual;
else
-- this is for the current month run
Select trunc(sysdate, 'MONTH') INTO V_LOWDATE FROM DUAL;
SELECT Last_Day(Sysdate) INTO V_Highdate From Dual;
end if;
end if;
Thanks

Noob needs help with this code...
Hi,
I found this code in a nice tutorial and I wanna make slight
adjustments to the code.
Unfortunately my Action Script skills are very limited... ;)
This is the code for a 'sliding menue', depending on which
button u pressed it will 'slide' to the appropriate picture.
Here's the code:
var currentPosition:Number = large_pics.pic1._x;
var startFlag:Boolean = false;
menuSlide = function (input:MovieClip) {
if (startFlag == false) {
startFlag = true;
var finalDestination:Number = input._x;
var distanceMoved:Number = 0;
var distanceToMove:Number =
Math.abs(finalDestination-currentPosition);
var finalSpeed:Number = .2;
var currentSpeed:Number = 0;
var dir:Number = 1;
if (currentPosition<=finalDestination) {
dir = -1;
} else if (currentPosition>finalDestination) {
dir = 1;
this.onEnterFrame = function() {
currentSpeed =
Math.round((distanceToMove-distanceMoved+1)*finalSpeed);
distanceMoved += currentSpeed;
large_pics._x += dir*currentSpeed;
if (Math.abs(distanceMoved-distanceToMove)<=1) {
large_pics._x =
mask_pics._x-currentPosition+dir*distanceToMove;
currentPosition = input._x;
startFlag = false;
delete this.onEnterFrame;
b1.onRelease = function() {
menuSlide(large_pics.pic1);
b2.onRelease = function() {
menuSlide(large_pics.pic2);
b3.onRelease = function() {
menuSlide(large_pics.pic3);
b4.onRelease = function() {
menuSlide(large_pics.pic4);
I need to adjust five things in this code...
(1) I want this menue to slide vertically not horizontally.
I changed the 'x' values in the code to 'y' which I thought
would make it move vertically, but it doesn't work...
(2) Is it possible that, whatever the distance is, the
"sliding" time is always 2.2 sec ?
(3) I need to implement code that after the final position is
reached, the timeline jumps to a certain movieclip to a certain
label - depending on what button was pressed of course...
I tried to implement this code for button number two...
b2.onRelease = function() {
menuSlide(large_pics.pic2);
if (currentPosition = finalDestination) {
this.large_pics.pic2.gotoAndPlay("s1");
--> sliding still works but it doesn't jump to the
appropriate label...
(4) I wanna add 'Next' & 'Previous' buttons to the slide
show - what would be the code in this case scenario ?
My first thought was something like that Flash checks which
'pic' movieclip it is showing right now (pic1, pic2, pic3 etc.) and
depending on what button u pressed u go to the y value of movieclip
'picX + 1' (Next button) or 'picX - 1' (Previous button)...
Is that possible ?
(5) After implementing the Next & Previous buttons I need
to make sure that when it reached the last pic movieclip it will
not go further on the y value - because there is no more pic
movieclip.
Options are to either slide back to movieclip 'pic1' or
simply do nothing any more on the next button...
I know this is probably Kindergarten for you, but I have only
slight ideas how to do this and no code knowledge to back it up...
haha
Thanx a lot for your help in advance !
Always a pleasure to learn from u guys... ;)
MikeHi,
I made some progress with the code thanx to the help of
Simon, but there are still 2 things that need to be addressed...
(1) I want the sliding time always to be 2.2 sec...
here's my approach to it - just a theory but it might work:
we need a speed that changes dynamically depending on the
distance we have to travel...
I don't know if that applies for Action Scrip but I recall
from 6th grade, that...
speed = distance / time
--> we got the time (which is always 2.2 sec)
--> we got the disctance
(currentposition-finaldestination)
--> this should automatically change the speed to the
appropriate value
Unfortunately I have no clue how the action script would look
like (like I said my action script skills are very limited)...
(2) Also, one other thing I need that is not implemented yet,
is that when the final destination is reached it jumps to a certain
label inside a certain movieclip - every time different for each
button pressed - something like:
if (currentPosition = finalDestination) {
this.large_pics.pic2.gotoAndPlay("s1");
that statement just doesn't work when I put it right under
the function for each button...
Thanx again for taking the time !!!
Mike -
I am stuck with this code- I definitely need a bail out
I would appreciate if a good samaritan could add this code for me. I am at my wits end.
The program I am trying to write is supposed to add students with their personal information and then display them in a GUI.
I should be able to select a student and add a grade for that student.
Finally I should be able to get the average for all the grades added for this student and display the average grade.
My challenge is how to obtain all the added scores and show the students average .
I understand my best shot is to use VECTOR API.
I tried to write someething but it did not work at , obviously due to inexperience.
I just can't figure how to link this average display window to the Get Average button.
A student can have any number of grades.
I need someone to show me the way, may be little "code guide" I am waaaay lost
Thanks in advance
Little Delmarie.

I had a look at your code and decided against showing you how to
modify it to do what you want....
Reason being that it's something of a mess. I guess the reason for that
mess is a combination of the fact that you're new to Java (new to
software in general?) and you're using Visual Age.
So, below is a very quick (far from perfect, I just knocked it up in my
lunch hour) example of the kind of approach I would take to the problem.
Feel free to take ideas from it and build them in to your code.
Whatever you do, don't hand it in as you own work. By all means, hand
it in in addition to your own work and maybe even get your
teacher to comment on it.
Oh yes, if you use it, chuck me some dukes form this and your earlier
post on the same subject. Too many folks these days are neglecting to
allocate dukes - don't be one of them!
Oh, one thing about using the app, double clicking on table entries
for students and grades brings up the appropriate dialog. To create
a new grade or delete the selected ones, use the "right mouse" context
menu.
Enjoy.

here is the revised code:
To anyone out there, can you guys run this code and help me debug it?
I'm really desperate as this is a school project of mine and the deadline is 7 hours away. I have already been working on it for 3 days, but the program is still very buggy.

HI, I need your help. How can I delete all data, when I do not have the special security code, which I didn´t remember ? I also think, that I never create this code before. But I cannot put my settings back.
You must remember the code, if you can't then take the phone and proof of purchase to an Apple Store.

hello sir,i need labview code for a code which is written in matlab...
clc;
close all;
clear all;
Ez= zeros(1,200);
Hy=zeros(1,200);
Ca=1;
Cb=.4519;
n=1;
while(n<1500)
for k = 2:200
Ez(k)=Ez(k) + Cb*(Hy(k)-Hy(k-1));
end
Ez(1)=1;
for k=1:199
Hy(k)=Hy(k)+Cb*(Ez(k+1)-Ez(k));
end
plot(Ez,'b')
hold on
plot(Hy,'r')
hold off
pause(0.001);
n=n+1;
end
thankuWell, this code is quite trivial and if you have to learn LabVIEW anyway, you might as well try to implement it.
A few things to remember:
The first array element in LabVIEW has index #0, while in matlab it has index #1, so everything dealing with array indices needs to be adjusted slightly.
The zeroes function equivalent is "initialize array".
Keep the array in a shift register as you update elements.
use FOR loops.
Use one of the graphs to display the data.

Need help getting this code to work
I am trying to get this code to work using "if else statment" but it will only do the first part and not do the second part in the else statement. Can anyone help me out? Here is the code:
var R1 = this.getField("Registration Fees1");
var R2 = this.getField("Registration Fees2");
var R3 = this.getField("Registration Fees3");
var R4 = this.getField("Registration Fees4");
var R0 = 0
if (R0 == 0)
event.value = Math.floor(R1.value);
else
event.value = Math.floor(R2.value + R3.value + R4.value);
I did notice that if I fiddled around this this part:
if (R0 == 0)
sometimes I can get the second part to work but not the first. I need it to do either or and this is getting frustrating.
I might also not even need "var R0 = 0". I put that there for the condition part. If that is what is causing the problem, I can take it out. But then what would the condition be? For this form, the default is 0 and then the calculation follows by user clicking on different prices. The first part is if they want to pay for the full conference and the second part is if they want to pay for either Monday, Tuesday or Wednesday or 2 of the 3 days. Is it possible to get this to work with both parts together? I am still stuck on getting just one or the other working. Any help would be greatly appreciated. Thanks in advance.I have posted this on another message board and a user by the name of gkaiseril offered this solution but it hasn't worked either.
// all four days
var R1 = this.getField("Registration Fees1").value;
// Monday
var R2 = this.getField("Registration Fees2").value;
// Tuesday
var R3 = this.getField("Registration Fees3").value;
// Wednesday
var R4 = this.getField("Registration Fees4").value;
var Fee = 0
event.value = ''; // default value
if (R1 != 'Off') {
Fee = Number(R1) + Fee;
} else {
if(R2 != 'Off') {
Fee = Number(Fee) + R2;
if(R3 != 'Off') {
Fee += Number(R3);
if(R4 != 'Off') {
Fee = Number(R4) + Fee;
event.value = Fee; -
Need a way of calling this code from a button
Hi all
I am sorry to have to ask this but I can not find any info on this.
I found this code somewhere on the net. I should be able to delete a folder with file inside of it.
I need to call this when a button is clicked.
CAN ANYONE HELP ME or show me away of deleting a folder with files inside from a button?
public static boolean deleteDir(File dir) {
dir = new File ("Epod Configuration/Config Files/Temp Image Files/");
if (dir.isDirectory()) {
String[] children = dir.list();
for (int i = 0; i < children.length; i++) {
boolean success = deleteDir(new File(dir, children));
// The directory is now empty
return dir.delete();First have your class implement the Actionlistener interface then do this:
//create a button object
Button b = new Button("Delete");
//listen for action on the button.
b.addActionListener(this);
//add the button to the container.
add(b);
//call the method to delete the directory when button is clicked.
public void actionPerformed(ActionEvent e) {
if ("Delete".equals(e.getActionCommand())) {
deleteDir(File dir); -

Do this code need to have BufferedInputStream?
Good day, Java Guru!
Here is my code:
BufferedInputStream inputStream = new BufferedInputStream(connection.getInputStream());
ByteArrayOutputStream byteOutput = new ByteArrayOutputStream();
byte[] result = new byte[128];
int totalBytes;
while((totalBytes = inputStream.read(result)) != -1) {
byteOutput.write(result, 0, totalBytes);
}Variable connection represents opened Socket connection which returns to us input stream with bytes.
Will it be effective to have BufferedInputStream while reading bytes if my approach also use byte[128] array to read them?The default size for the buffer in BufferedInputStream is 4096. So, by using it in this code you will save 31 out of every 32 physical reads to the socket, i.e. 31/32 system calls, context switches, ... I believe you will find that it is beneficial. On the other hand if you were to use a bugger byte array, such as 4096 or more, you would find the BufferedInputStream to be a cost.
But as the other poster suggested you could have tested and measured this for yourself.
BTW it is rarely a good idea to read an entire socket stream into memory unless you know in advance that it's not very large. Consider what will happen if it's a multi-gigabyte movie. It's generally best to put it somewhere piece by piece, or parse it piece by piece as it comes in. -
