HOW TO MAKE A BOOLEAN FUNCTION IN LABVIEW5.0

I want to use a boolean funtion but it does not exist in existing functions?so how can I do it?I final aim is how to make a VALVE boolean function and how to use it?please teach me,experts! Thank you very much!

Hi,
what do you mean by "boolean function"?
For boolean operations you can use
1. Case structure. It is located in Functions->Structures
2. Boolean functions (such as AND, OR, NOT, etc.). They are located in Functions->Boolean
3. Comparison functions (such as equal?, greater?, less?, etc.). They are located in Functions->Comparison
You have to give more info about your problem.
Good luck.

How to Use a boolean function in a process

Hi,
I created a boolean function named change_pwd with 3 varchar2 parameters : login_name, old-pwd and new_pwd. I would like to use it in a process but I can't, this is how I do it : 
select change_pwd (
v('P12_Login'),v('P12_Old_Pwd'),v('P12_New_Pwd')) from dual;
 
Benn

I got this error : 
ORA-06550: line 2, column 8: PLS-00382: expression is of wrong type ORA-06550: line 2, column 1: PLS-00428: an INTO clause is expected in this SELECT statement
 
and here is my function : 
create or replace function "CHANGE_PWD" 
(p_username in VARCHAR2, 
p_old_password in VARCHAR2, 
p_new_password in VARCHAR2) 
return boolean 
is 
l_count number; 
l_password varchar2(4000); 
l_stored_password varchar2(4000); 
l_idcontact number; 
begin 
-- Check to see if the user is in the user table 
select count(*) into l_count from CONTACTS where MATRICULE = p_username; 
if l_count > 0 then 
-- take the stored password 
select u.MOTDEPASSE, u.IdContacts into l_stored_password, l_idcontact from UTILISATEURS u, CONTACTS c where u.IdContacts = c.IdContacts AND c.MATRICULE = p_username; 
 
-- apply the cash function 
l_password := user_hash(p_username, p_old_password); 
 
-- compare the hashed password with the stored password 
if l_password = l_stored_password then 
-- change password 
update UTILISATEURS set MotDePasse = user_hash(p_username, p_new_password) where idcontacts = l_idcontact;
return true; 
else 
return false; 
end if; 
else 
return false; 
end if; 
end;

How to make the wdDoIniiit() function executived twice in the view of WebDy

Hi Guyes, How can i make the wdDoIniiit() function executived twice in the view of WebDynpro? Thank you

Hi
WdDoInit() :- This is called only once when the View is loaded freshly.
WdDoModifyView:- Called every time an action is performed on the View.
It is called by webdynnpro runtime environment for modification of the view layout.
For all the views,this takes place at a time immediately before the closing response renders.

How to make Ctrl + N function as down key in finder

I want to make Ctrl + N function as down key and Ctrl + P function as up key in finder application for easy keyboard navigation. How can i do this?

You're misinterpreting the way the Keyboard shortcuts you add in preferences work.
For you to be able to turn the key sequence into a shortcut for some action that action has to exist as a menu item in the application. That is if you want to make say Show Clipboard (one menu item without a shortcut already assigned) you would put the command Show Clipboard into the section Menu Title and ad the key sequence in the Keyboard Shortcut section.
But as there is no menu item for down one line in Finder there is nothing to put into the Menu Title section so no way to map it.
As it turns out for text editing OS X already recognizes ^N as down one line (in fact a lot of the Emacs key bindings are recognized out of the box) Unfortunately these only apply to editing situations. There is no way I know of to map motion commands like you are looking to do here.
There is the possibility of adding a keybindings dictionary to your home library folder, google for something like emacs key bindings mac mavericks
<edit> I dont't think you'll be able to do it this way either but it is worth a look</edit>

How to make a Predefined function out of this

I am new into java, and I wanted to define certain sets of command into a single function to avoid redundancy and to have a much shorter code. Below is the problem,
import java.sql.*;
import java.io.*;
public class Ivatanako
static void displayResult(){
name = resultSet.getString(2);
                         idnum = resultSet.getString(3);
                         mach1 = resultSet.getString(4);
                         mach2 = resultSet.getString(5);
                         q1 = resultSet.getDouble(6);
                         q2 = resultSet.getDouble(7);
                         q3 = resultSet.getDouble(8);
                         rsf = resultSet.getDouble(10);
                         fg = resultSet.getDouble(11);
     public static void main(String args[])
               DataInputStream input=new DataInputStream(System.in);
try
               Class.forName("sun.jdbc.odbc.JdbcOdbcDriver").newInstance();
               Connection conn = DriverManager.getConnection("jdbc:odbc:;DRIVER=Microsoft Access Driver (*.mdb);DBQ=c:\\db.mdb;PWD=mypass","login","password");
               Statement command = conn.createStatement();
if (option==1){
                         System.out.println("Enter name: ");
                         stdName = input.readLine();
                         resultSet = command.executeQuery("SELECT * from Students where stud_name='" + stdName + "'");
                         while (resultSet.next( )) {
                         displayResults();
                         allRecords(name, idnum, mach1, mach2, q1, q2, q3, rsf, fg);
conn.close();
     catch (SQLException se)
               System.out.println(se);
          catch (Exception ex)
               System.out.println(ex);
}It always returns a "undeclared" error.. How to fix this? Rather how to declare a predefine function that contains ResultSet's?

static void displayResult()static void displayResult(ResulteSet resultSet)
displayResults();displayResults(resultSet);

You can use any number of the String methods to acomplish this.
I would proabably go with something like: slice(...) + input + substr(...);

How to make the scrollbar function with mouse scroll wheel?

Is there a way how to make my content scroll even with the mouse scroll wheel?... I have to edit the coding??

Hey!
You shouldn't have to edit any code.
There is an active player bug surrounding this issue however, which causes the following:
1) It should work on windows.
2) It may not work on Mac.
We're continuing to pursue this issue, we know it's important to our users.
Thanks,

How to make a dynamic function call from within a package procedure

Hi:
I need to call a function dynamically (name and parameters determined at run time, but return value is known:always an integer). I can build the call and place it in a dynamic sql using dbms_sql. But the function is inside a package and is not public.
So, if I issue:
dbms_sql.parse( cur,'SELECT '||call||' FROM dual', dbms_sql.v7 )
where call is "DOS(234,'V')"
I get:
ORA-00904: "DOS": invalid identifier
If I make the function ("DOS") public and "call" equals "pack.DOS(234,'V')", it works fine, but I don't want to make it public.
Is there a solution?
Thanks in advance
RuBeck

Hi, Kamal:
Calling from outside of the owner package is not possible if it is not public.The calls are from inside the package. It looks like the dynamic select is executed "outside" the package, so the private function is unknown
Make it available in the package headerLooks like it's the only solution
How often this will be executed?This is a library for loading files into tables and executing dynamic validation procedures.
Here's an example of the mechanics:
create or replace package mypack as
function one return number ; -- public function
procedure execute_it( p_name VARCHAR2 ) ;
end ;
create or replace package body mypack as
function one return number is
begin
return 1 ;
end ;
function two( i number, s varchar2 ) return number is -- private function
begin
return 2 ;
end ;
procedure execute_it( p_name VARCHAR2 ) is
select_str VARCHAR2( 1000 ) ;
v_num NUMBER ;
cur NUMBER ;
nf NUMBER ;
begin
select_str := 'SELECT '||p_name||' FROM dual' ;
cur := dbms_sql.open_cursor ;
dbms_sql.parse( cur,select_str,dbms_sql.v7 ) ;
dbms_sql.define_column( cur,1, v_num ) ;
nf := dbms_sql.execute( cur ) ;
IF dbms_sql.fetch_rows( cur ) = 0 THEN
RAISE no_data_found ;
END IF ;
dbms_sql.column_value( cur, 1, v_numero ) ;
dbms_output.put_line( p_name||' returns '||v_num ) ;
dbms_sql.close_cursor( cur ) ;
end ;
end ;
begin
mypack.execute_it( 'mypack.one' ) ; -- Call public function: Works fine
mypack.execute_it( 'two(234,''v'')' ) ; -- Call private function: error 0904
end ;
Thanks for your hints

How to make a normal Function Module remote able function module

Hi guys,
i am a beginner in abap programming. I have made a programm in Se80 which shows all the nodes of the active hierarchies (5 stk.)
in a ALV grid. Therefore i am getting the active hierarchies from table "rshiedir" and use the normal function module "RSSH_HIERARCHY_READ" to display the nodes of the hierarchie. The problem is the hierarchies do have a different techical name in the systems (development-acceptance-productive) but the descriptive nbame is the same in all systems. Because of the difference of the technical names I can use this programm in just one system. But the hierarchy content should be comparable and be displayed in all three systems. Therefore i would like to create a remoteable function module which covers the normal one. Can i do this and how can i create a remoteable function module and use it?
If not do you know any remotable functgion module which gives back all the nodes from an active hierarchy in table "RShiedir".
Thanks and kind regards,
Murat

Hello,
Simple, create a wrapper RFC (similar to 'RSSH_HIERARCHY_READ' ) & call the normal FM 'RSSH_HIERARCHY_READ' inside the wrapper.
Something like this:
FUNCTION z_rssh_hierarchy_read.
*"*"Global Interface:
*" IMPORTING
*" VALUE(I_RSHIEDIRKEY) TYPE RSHI_S_RSHIEDIRKEY OPTIONAL
*" VALUE(I_RSHIEDIRLOG) TYPE RSHI_S_RSHIEDIRLOG OPTIONAL
*" VALUE(I_DATE) TYPE RSHI_DATE DEFAULT SY-DATUM
*" EXPORTING
*" REFERENCE(E_RSHIEDIR) TYPE RSHI_S_HIEDIR
*" REFERENCE(E_T_RSNODES) TYPE RSHI_T_HIENODE
*" REFERENCE(E_TH_RSINTERVAL) TYPE RSHI_TH_INTERVAL
*" REFERENCE(E_DUPLICATE_LEAFS) TYPE RS_BOOL
*" REFERENCE(E_T_RSNODES_LNK) TYPE RSHI_T_HIENODE
*" EXCEPTIONS
*" INVALID_HIERARCHY
*" NAME_ERROR
*" IOBJ_NOT_FOUND
" Don't forget to add TYPE-POOLS rshi to the FuGr. TOP include
CALL FUNCTION 'RSSH_HIERARCHY_READ'
 EXPORTING
 i_rshiedirkey = i_rshiedirkey
 i_rshiedirlog = i_rshiedirlog
 i_date = i_date
 IMPORTING
 e_rshiedir = e_rshiedir
 e_t_rsnodes = e_t_rsnodes
 e_th_rsinterval = e_th_rsinterval
 e_duplicate_leafs = e_duplicate_leafs
 e_t_rsnodes_lnk = e_t_rsnodes_lnk
 EXCEPTIONS
 invalid_hierarchy = 1
 name_error = 2
 iobj_not_found = 3
 OTHERS = 4.
IF sy-subrc <> 0.
* MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
* WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
Here Z_RSSH_HIERARCHY_READ is the wrapper RFC. Hope you get the point.

How to make a fully functioning form in Acrobat 8

I am trying to make a form in Acrobat 8 and when i send it to a PC to be tested, they get an error.It says"This operation is not permitted" when they click the submit button. ANy idea how i csn fix this? it works fine on my laptop.
Please help!

It sounds like you're trying to submit the entire PDF using Reader. For this to work, the document has to be Reader-enabled. Acrobat 8 Pro can do this by selecting: Advanced > Enable Usage Rights in Adobe Reader.
Some newer versions of Reader may have a problem with a form enabled in Acrobat 8, so you'll have to test it out.

How to make the recv function in winsock2 stop after a specific time..?

In an developing a Windows Desktop Console Application in c++ in Visual Studio 3013 for Windows Desktop, which acts as a client and tries to connect to a server. Once the Connection with the server is successful, it sends a handshaking signal to the
server and waits for a response from the server. Iam using winsocks2 in this application. The receive function I am using is a blocking call
iResult = recv(ConnectSocket, recvbuf, recvbuflen, 0);
So until my server sends a response, the client is blocked. What I need is the client to check for response only for a certain time (say 10 sec). If there is no response within this time frame ,I want the client to disconnect from the server. How to achieve
this?

You could use setsockopt

to set the timeout option, SO_RCVTIMEO, for the recv
function.

How to make "open file" function

Is there a method that you can call that can prompt the user to open a file? Here is what I have:
var file:FileReference = new FileReference;
var newFile:BitmapData = new BitmapData (600,290,false);
newFile.draw(file.upload(file.browse()));
var s:Shape = new Shape();
s.graphics.beginBitmapFill(newFile);
s.graphics.drawRect(0, 0, board.width, board.height);
s.graphics.endFill();
board.addChild(s);
What would I put in the line in bold to achieve this?

How do I convert the File Reference to the bitmap data or a shape? This is what I have right now:
var file:FileReference = new FileReference();
var newFile:BitmapData = new BitmapData(600,290,false);
file.browse();
var selectedFile:FileReference;
file.addEventListener(Event.SELECT, file);
function f(e:Event)
var selectedFile = FileReference(e.target);
newFile.draw(e.target);
var s:Shape = new Shape();
s.graphics.beginBitmapFill(newFile);
s.graphics.drawRect(0, 0, board.width, board.height);
s.graphics.endFill();
board.addChild(s);

How to make a "save" function?

Hi everybody
I am a novice and this is my first time to ask here
I have seen a RPG flash game which have a "save" function
although it is offline
Could anyone tell me how can it do that please

Look up the SharedObject class in the Help. If they're not
sending the info
to a server-side database, then they're using a SO.

How to make an onKeyPressed function work

Hi, i have some problems with making the onkeyPressed function work. Somehow when i run it, it complains about "'static' is no longer supported. It will be removed from the language soon. Use script-level declarations for Right ". So i need to get around it. Here's the code. Make an image or replace an image with spacecraft.png.
var frame = 0;
var spaceship: ImageView;
var Spaceship = Image { url: "{__DIR__}spacecraft.png" }
var KeyX: Number = 100;
var KeyY: Number = 100;
var offsetX: Integer;          // Possible values are -1, 0 and 1
var offsetY: Integer;
var x;
var MoveLeft;
var MoveUp;
var MoveDown;
var transition: Transition;
Stage {
visible: true
title: "Spaceship"
scene: Scene {

height: 200
content: [
ImageView {
image: Spaceship
onKeyPressed: function(e: KeyEvent): Void {
if (e.code == KeyCode.VK_RIGHT) {
Move.Right
if (e.code == KeyCode.VK_LEFT) {
var y: Number = 200;
var X: Number = 200;
// Timeline updates y variable

translateY: 100
fitWidth: 150
transition: TranslateTransition {
duration: 2s
byX: 250 repeatCount: Timeline.INDEFINITE
autoReverse: true
}

I tried the node.requestFocus(), but apparently, their is a new error when I ran it . It said "java.lang.StackOverflowError" with many at errors following it .Here our my fx codes. If you run it on your IDE, it should say the same error.
Main.Fx

How to make a fully functional eNewsletter and not dye trying

Hi all.
I´m trying to make eNewsletter with iWeb. I think i make the right way, but maybe i´m making something wrong.
First: I make a new page with iWeb, insert hmtl of my images that are hosted in my server, i insert some text with some links... i save it... and i publish it on my server.
When i try to open on a web explorer (such as Safari, Firefox, etc...) i have the LINE 1 parse error. I use to solution it editing the html file and deleting the first line. Then, I can see now the website in all the web explorers. But I see that in Safari all the web is funny, but in Firefox all the images have a FRAME! Why?
Second. I use Safari->Send web by Mail->to some of my contacts. When the emails are received, some mail clients (such Mail, Entourage, Outlook...) received fine the newsletter. But the webmail based like Hotmail, Gmail, Yahoo... received distorted all the newsletter. Somebody know why? Somebody can help me?
I have an enterprise and i need this function to give a good promotion for my products. I don´t have html knowledges, i´m not a programmer. And I think iWeb is a funny software to make my purpose, but I think the software has some bugs like i write here.
Well, thanx to all, wait your words.

Welcome to the discussions.

I agree — so here are some alternative approaches:
