Break on boolean wire state
This seems basic but I can't find any way to set a breakpoint on a wire that carries a boolean state that stops execution when the state goes to FALSE. Is there any way to do that?
Solved!

Bug? LabVIEW-2009: Boolean wire missing some dots
I opened a VI from someone asking a question on this forum and noticed some missing dots on two boolean wires.
This was opened using LV 2009. It's an Evaluation installation (in case someone is wondering about specifics).
I minimized and maximized the block diagram and the dots were okay.
I don't know if this was already reported.

Of course we could also ask for underground wires that could be threaded below the diagram for some busy areas where they are not needed.

How to trigger two Actions at a time in a break function(Boolean)
Hi All
I am using three sequential Blocks.First Block is to enter the data and send to second Block. When second sequential Block accepts it should sent to third Block. If Second Block rejects the form then I want to stop (Terminate) the process and I want to send the notification.
I am using Pre-conditional block and checking check box in the second block to accept or reject the initial form. If I use Boolean function it automatically declare two functions one is Continue and another is Break. If I select break then I am not able to send any notification or any callable object as this break function will break the process at instant and it wont allow any further actions.
Thanks & Regards,
Syed Nawaz.SI think you just need to use 2 sequential blocks. Seq Block 1 will contain your data input form. Seq Block 2 will contain 5 actions - 1st action is a Decision Dialog (that will have Continue and Break), 2nd Action is whatever needs to be done on Continue, 3rd Action is Terminate, 4th Action is Send Notification and 5th Action is Terminate. Set the target for Continue to Action #2 and target for Break is Action #4. Once 2 is executed it will execute Action #3 and the process will terminate. If the Break situation is executed, a notification will be sent and the process will terminate.
Thanx,

Problems with booleans - Unreachable Statement.
Hey,
at the top of my class I have Random() declared like so...
private static Random noise = new Random();
and further down I'm trying to do an IF statement like so....
if(noise.nextBoolean() == true)
makeBetterSB.reverse();
the IDE displays an error of "Unreachable Statement".
What have I done wrong?We would have to know which statement the compiler said was unreachable to answer that. We would also have to know what comes before that statement, because it's the code before that statement that causes it to be unreachable.

I am attempting to transfer positional data (on a predetermined route) overlaid on a map and indications of boolean output states to secondary computer through datasocket (LabVIEW 8.6, Datasocket 4.5). Is it required to compress all these parts into an array which is bundled and transmitted to the secondary computer which then would have to be unbundled and separated out of the array? Is this the only option, or are there other methods? Also how would we go about these methods?
Hi Maruti,
It seems like the way you described would be the way to do it unless you wanted to pass all the data seperately.
Check out this KB relating to passing clusters through datasocket: http://digital.ni.com/public.nsf/allkb/1085057DB6F930058625672400646805?OpenDocument

Advice on breaking up Stacked Sequences in 6.1?
I've dived right into an old but functional
test system ~300 VI's. Flow and structure is pretty hard to follow and
I'm thinking of breaking it up into state machines.
Any ideas on how to approach a stacked sequence beast in 6.1? Flat sequence seems crucial to the method described here.
Rough layout of main vi attached:
Attachments:
main.PNG 46 KBOpen your VI in LV 8.x and use the method described in your linked thread ;-)
You can copy the sequence and remove it while displaying frame 0 in the original and frame 1 in the copy. If you have controls/indicators they will be duplicated. Also, wire connections via sequence locals will be lost. So you will have to rewire and clean up your code. But I think there's no straightforward solution because flat sequences didn't exist in 6.1. -
Using a Switch statement for Infix to Prefix Expressions
I am stuck on the numeric and operator portion of the switch statement...I have the problem also figured out in an if/else if statement and it works fine, but the requirements were for the following algorithm:
while not end of expression
switch next token of expression
case space:
case left parenthesis:
skip it
case numeric:
push the string onto the stack of operands
case operator:
push the operator onto the stack of operators
case right parenthesis:
pop two operands from operand stack
pop one operator from operator stack
form a string onto operand stack
push the string onto operand stack
pop the final result off the operand stack
I know that typically case/switch statement's can only be done via char and int's. As I said I am stuck and hoping to get some pointers. This is for a homework assignment but I am really hoping for a few pointers. I am using a linked stack class as that was also the requirements. Here is the code that I have:

Characters from db column break my app
Hello,
I seem to have a problem in my application where some of the db columns have single quotes or characters that break either my sql statements for the report, or the error could also steam from the report template I created.
The error I get is:
ORA-06550: line 1, column 43: PLS-00103: Encountered the symbol "ABCDE" when expecting one of the following: ) , * & | = - + < / > at in is mod remainder not rem => .. <> or != or ~= >= <= <> and or like LIKE2_ LIKE4_ LIKEC_ as between from using || multiset member SUBMULTISET_Hi,
If its just a text item could select Display As Text(escape special characters) in the field attributes.
You could also use some of the built string comparison validations (ie. is alphanumeric)
Kind regards,

Convert rows to columns and put line break in between using t-sql
Hi,
I have a table with 5 columns..and my source data looks like this..
RecordID ID Display AddressType EmailAddress
1 1 GeneratedBy From
[email protected]
1 1 ReceivedBy To
[email protected]
1 1 ReceivedBy To
[email protected]
2 1
3 1 GeneratedBy From
[email protected]
3 1 GeneratedBy From [email protected]
3 1 ReceivedBy To
[email protected]
I need t-sql to show output as..
RecordID ID FullDisplay
1 1 GeneratedBy From -
[email protected] < CHAR(13) - Need Line Break here so that it goes to 2nd line>
ReceivedBy To -
[email protected] ; To -
[email protected]
2 1 Null
3 1 GeneratedBy From -
[email protected] ; From -
[email protected] < CHAR(13) - Need Line Break here so that it goes to 2nd line>
ReceivedBy To -
[email protected]
Display field will have 3 values - "GeneratedBy" , "ReceivedBy" or Null
AddresType field will have 3 values - "From" , "To" and Null.
In the above example, Those 7 records belongs to ID=1.
Whenever RecordID is same I want to show everything in one line with line breaks in between.
In the above example RecordID=1 has 3 rows, display it as 1 row. But Whenever 'ReceivedBy' is there for same recordID put a line break before "ReceivedBy"

Most efficient way to track 3 states?
In a program I am writing, I have an object with three states, which it progresses through during the corse of the program. Since the program uses a lot of these objects (potentially) I want to keep the size of them down. Here's the issue. How to store what state the object is in? a boolean won't work, of corse, since there are three states. So here's what I can up with:
Either a Boolean (initial state is null, then false, then true)
or a byte (any three values would work)
I have a feeling that the byte is more efficient, but want to make sure. Also, if I'm missing an easy, efficient way to do this, tell me.Nearly there:
<code>
public abstract class State {
abstract void handleState();
abstract int getState();
public class State1 extends State {
void handleState() {
//do state 1 specific stuff
int getState() {
return 1;
public class State2 extends State {
void handleState() {
//do state 2 specific stuff
int getState() {
return 2;
public class State3 extends State {
void handleState() {
//do state 3 specific stuff
int getState() {
return 3;
public class StateController {
private State currentState = new State1();
public int getState() {
return currentState.getState();
public void handleState() {
currentState.handleState();
</code>
might work ;)
As to booleans... no they cannot be null actually... they are represented by a bit which is 0 or 1 (or if you prefer true of false).
Boolean b = null;
is not a null boolean, it is an uninitialised object.
If you need an Object that you want to be a boolean then it is fine to use the Boolean class :)
The reason boolean b: b == null doesn't compile is because you cannot compare different types. -
explain
on change of
endon.
at new
endat.<b>ON CHANGE OF </b>
Syntax
ON CHANGE OF dobj [OR dobj1 [OR dobj2] ... ].
statement_block
ENDON.
Effect:
The statements ON CHANGE OF and ENDON, which are forbidden in classes, define a control structure that can contain a statement block statement_block. After ON CHANGE OF, any number of data objects dobj1, dobj2... of any data type can be added, linked by OR.
Example:
In a SELECT loop, a statement block should only be executed if the content of the column CARRID has changed.
DATA spfli_wa TYPE spfli.
SELECT *
FROM spfli
INTO spfli_wa
ORDER BY carrid.
ON CHANGE OF spfli_wa-carrid.
ENDON.
ENDSELECT.
The following section of a program shows how the ON control structure can be replaced by an IF control structure with an explicit auxiliary variable carrid_buffer.
DATA carrid_buffer TYPE spfli-carrid.
CLEAR carrid_buffer.
SELECT *
FROM spfli
INTO spfli_wa
ORDER BY carrid.
IF spfli_wa-carrid <> carrid_buffer.
carrid_buffer = spfli_wa-carrid.
ENDIF.
ENDSELECT.
<b>ENDON </b>
Syntax
ENDON.
Effect
The ENDON statement closes a conditional statement block introducud by ON CHANGE OF.
<b>AT - itab </b>
Syntax
LOOP AT itab result ...
[AT FIRST.
ENDAT.]
[AT NEW comp1.
ENDAT.
[AT NEW comp2.
ENDAT.
AT END OF comp2.
ENDAT.]
AT END OF comp1.
ENDAT.]
[AT LAST.
ENDAT.]
ENDLOOP.
Extras:
1. ... FIRST
2. ... |{END OF} comp
3. ... LAST
Effect
The statement block of a LOOP loop can contain control structures for control level processing. The respective control statement is AT. The statements AT and ENDAT define statement blocks that are executed at control breaks. Within these statement blocks, the statement SUM can be specified to total numeric components of a group level. In the case of output behavior result, the same applies as for LOOP AT.
So that group level processing can be executed correctly, the following rules should be noted:
After LOOP there should be no limiting condition cond specified.
The internal table must not be modified within the LOOP loop.
The work area wa specified in the LOOP statement after the INTO addition must be compatible with the line type of the table.
The content of a work area wa specified in the LOOP statement after the INTO addition must not be modified.
The prerequisite for control level processing is that the internal table is sorted in exactly the same sequence as the component of its line type - that is, first in accordance with the first component, then in accordance with the second component, and so on. The line structure and the corresponding sorting sequence gives a group structure of the content of the internal table, whose levels can be evaluated using AT statements. The AT-ENDAT control structures must be aligned one after the other, in accordance with the group structure.
The statement blocks within the AT-ENDAT control structures are listed if an appropriate control break is made in the current table line. Statements in the LOOP-ENDLOOP control structure that are not executed within an AT-ENDAT control structure are executed each time the loop is run through.
If the INTO addition is used in the LOOP statement to assign the content of the current line to a work area wa, its content is changed upon entry into the AT-ENDAT control structure as follows:
The components of the current group key will remain unchanged.
All components with a character-type, flat data type to the right of the current group key are set to character "*" at that position.
All the other components to the right of the current group key are set to their initial value.
When the AT-ENDAT control structure is exited, the content of the current table line is assigned to the entire work area wa.

Continue in a switch statement
What is the difference between using unlabelled continue and break in a switch statement?
Looks like there is the same effect but I didn't found anything about using continue in switch in any documentation.
Here's a typical explanation of using switch statement:
"If the condition in a +switch statement+ matches a case constant, execution will run through all code in the +switch+ following the matching case statement until a +break statement+ or the end of the +switch statement+ is
encountered. In other words, the matching case is just the entry point into the case block, but *unless there's a break statement*, the matching case is not the only case code that runs"
Is it a good practise to use continue instead of break in such case?Books are right again :))
Thanks everybody who wrote here.
As I found out continue is only for use in the loop statements. I just use continue inside both for and switch statements and that's why I thought that it's appropriate to use it inside switch. No way!! In this way continue will affect only loop, not switch statement.
For example:
class BreakTest {
public static void main(String[] args) {
BreakTest br = new BreakTest();
br.testContinue();
br.testBreak();
public void testContinue() {
int[] int_arr = { 0, 0, 0, 0, 1, 0, 0 };
int count_in_switch = 0;
int count_in_for = 0;
for (int a : int_arr) {
switch (a) {
case 0:
continue;
default:
count_in_switch++;
count_in_for++;
System.out.println("count_in_switch=" + count_in_switch
+ " count_in_for=" + count_in_for);
public void testBreak() {
int[] int_arr = { 0, 0, 0, 0, 1, 0, 0 };
int count_in_switch = 0, count_in_for = 0;
for (int a : int_arr) {
switch (a) {
case 0:
break;
default:
count_in_switch++;
count_in_for++;
System.out.println("count_in_switch=" + count_in_switch
+ " count_in_for=" + count_in_for);
count_in_switch=1 count_in_for=*1*
count_in_switch=1 count_in_for=*7*
In case of using continue you won't get to count_in_for++; - you'll jump to the next iteration of for loop.
In case of using break you'll go out of switch and go to next statement, that goes after switch block -
Hi,
I'm using WebLogic 9.2.2. I have a single server in my cluster. The server is perpetually stuck in a "STARTING" state (http://screencast.com/t/GMDTihmVYD). I'm not sure how it got there, but when I visit the Shutdown -> Force Shutdown Now option, although I'm told the request was sent to the server, the server remains in this ambiguous "STARTING" state.
How do I break out of this state and restart my server?
Thanks, - DaveOn your advice, logged in as etsbea, I ran the command, filtered with java and got:

What is the use of at new statement?
What is the use of at new statement?
Hi,
AT - itab
Syntax
LOOP AT itab result ...
[AT FIRST.
ENDAT.]
[AT NEW comp1.
ENDAT.
[AT NEW comp2.
ENDAT.
AT END OF comp2.
ENDAT.]
AT END OF comp1.
ENDAT.]
[AT LAST.
ENDAT.]
ENDLOOP.
Extras:
1. ... FIRST
2. ... |{END OF} compi
3. ... LAST
Effect
The statement block of a LOOP loop can contain control structures for control level processing. The respective control statement is AT. The statements AT and ENDAT define statement blocks that are executed at control breaks, that is, when the control structure is changed. The additions to the AT statements determine the control break at which their statement blocks are executed. Within these statement blocks, the statement SUM can be specified to add together the numeric components of a control level. For the output behavior result, the same applies as for LOOP AT.
The prerequisite for control level processing is that the internal table is sorted in exactly the same sequence as the component of its line type - that is, first in accordance with the first component, then in accordance with the second component, and so on. The line structure and the corresponding sorting sequence gives a group structure of the content of the internal table, whose levels can be evaluated using AT statements. The AT- ENDAT control structures must be aligned one after the other, in accordance with the group structure.
The statement blocks within the AT- ENDAT control structures are listed if an appropriate control break is made in the current table line. Statements in the LOOP- ENDLOOP control structure that are not executed within an AT- ENDAT control structure are executed in each pass of the loop.
In order that control level processing is carried out properly, the following rules must be observed:
After LOOP, a restricting condition cond can only be specified if this selects a consecutive line block of the internal table. Otherwise, the behavior of control level processing is undefined.
The internal table cannot be modified within the LOOP loop.
A work area wa specified in the LOOP statement after the addition INTO must be compatible with the line type of the table.
The content of a work area wa specified after the addition INTO in the LOOP statement must not be modified.
If the INTO addition is used in the LOOP statement to assign the content of the current line to a work area wa, its content is changed upon entry into the AT-ENDAT control structure as follows:
The components of the current control key remain unchanged.
All components with a character-type, flat data type to the right of the current control key are set to character "*" in every position.
All the other components to the right of the current control key are set to their initial value.
When the AT-ENDAT control structure is exited, the content of the current table line is assigned to the entire work area wa.
Addition 1
... FIRST
Effect
The control level is defined by the first line of the internal table. The control break takes place when this line is read.
Note
In the group level AT FIRST, the current group key contains no components and all character-type components of the work area wa are filled with "*" and all remaining components are set to their initial value.
Addition 2
... |{END OF} compi/>
Effect
: Control levels are defined by the beginning or end of a group of lines with the same content in the component compi (where i = 1, 2, and so on) and in the components to the left of compi. The control breaks take place when the content of the component compi or another component to the left of compi changes.
The compi components can be specified as described in Specification of Components, with the limitation that access to object attributes is not possible here.
Note
If the INTO or ASSIGNING additions are used in the LOOP statement, a field symbol can be entered after AT |{END OF} outside classes, to which the corresponding component of the work area wa or the field symbol <fs> is assigned. This form of dynamic component specification is obsolete and has been replaced by specification in the format (name).
Addition 3
... LAST
Effect
: The control level is defined by the last line of the internal table. The control break takes place when this line is read.
Note
In the group level AT LAST, the current group key contains no components and all character-type components of the work area wa are filled with "*" and all remaining components are set to their initial value.

How to reset a particular view object alone to it's initial state??
Hi,
My application contains view objects with custom data source implementation. One of my requirement is to reset the particular view object alone to it's initial state. I can't use rollback since it is at Db Transaction level. I searched in forums and finally written the following coding to achieve it. It works fine during sometime but sometimes i am getting the exception oracle.jbo.DeadEntityAccessException: JBO-27101: Attempt to access dead entity in Person, key=oracle.jbo.Key[1 -10 ]
public void resetPersonViewObject(String voName) {
Iterator dirtyItr = this.getEntityDef(0).getAllEntityInstancesIterator(this.getDBTransaction());
while (dirtyItr.hasNext()) {
Object obj = dirtyItr.next();
if (obj instanceof EntityImpl) {
EntityImpl entity = (EntityImpl)obj;
String state = null;
byte entityState = entity.getEntityState();
switch (entityState) {
case Entity.STATUS_INITIALIZED:
state = "Initialized";
// Don't do anything
break;
case Entity.STATUS_UNMODIFIED:
state = "Un-Modified";
// Don't do anything
case Entity.STATUS_DEAD:
state = "Dead";
// Don't do anything
break;
case Entity.STATUS_DELETED:
state = "Deleted";
entity.revert();
// entity.refresh(Entity.REFRESH_CONTAINEES);
break;
case Entity.STATUS_MODIFIED:
state = "Modified";
entity.refresh(Entity.REFRESH_UNDO_CHANGES);
break;
case Entity.STATUS_NEW:
state = "New";
entity.refresh(Entity.REFRESH_FORGET_NEW_ROWS);
entity.refresh(Entity.REFRESH_REMOVE_NEW_ROWS);
break;
System.err.println("State : " + state);
getDBTransaction().clearEntityCache(getEntityDef(0).getFullName());
getViewObject().clearCache();
}Questions:
1. How to achieve my requirement? Is there any code correction required?
2. How to reset the row which is actually deleted by the user?
3. The sample code shown above is applicable for all the view object instances which are created from the same entity? What should i do if i want to reset a particular instance of a view object (I may use different instance of same view object at various screens whereas i want to reset only one)
Can anyone help on this??
Thanks in advance.

Edited by: Raguraman on Apr 24, 2011 8:48 PMHi,
As per my requirement, i use various instances of same view object in various dynamic tabs only. Since each tab has its own transaction, refreshing an EO of a particular transaction will refresh only the VO instances which comes under that transaction. So it will not cause any issue for my requirement i hope.
Requirement: Need to reset a particular entity driven view object instances.
Tried Schema: Departments table of HR Schema. Tried using the Application Module tester.
Code i use:
// Client Interface method of DepartmentsViewImpl
public void resetView() {
Iterator dirtyItr =
this.getEntityDef(0).getAllEntityInstancesIterator(this.getDBTransaction());
while (dirtyItr.hasNext()) {
Object obj = dirtyItr.next();
if (obj instanceof EntityImpl) {
EntityImpl entity = (EntityImpl)obj;
byte entityState = entity.getEntityState();
switch (entityState) {
case Entity.STATUS_UNMODIFIED:
break;
case Entity.STATUS_INITIALIZED:
break;
case Entity.STATUS_DEAD:
break;
case Entity.STATUS_DELETED:
entity.refresh(Entity.REFRESH_WITH_DB_FORGET_CHANGES);
break;
case Entity.STATUS_MODIFIED:
entity.refresh(Entity.REFRESH_UNDO_CHANGES);
break;
case Entity.STATUS_NEW:
entity.refresh(Entity.REFRESH_FORGET_NEW_ROWS);
entity.refresh(Entity.REFRESH_REMOVE_NEW_ROWS);
break;
getDBTransaction().clearEntityCache(getEntityDef(0).getFullName());
getViewObject().clearCache();
Issue i have:
1. Add a blank row (Soon transaction has become dirty). Call the resetView() client interface. It gives me JBO-25303: Cannot clear entity cache model.eo.Departments because it has modified rows
2. Modify any row and then delete the same row. Call the resetView(). It gives me JBO-27101: Attempt to access dead entity in Departments, key=oracle.jbo.Key[10 ]
[NOTE: Above code works fine when for simple deletion of rows, modification of existing rows, new rows]
