Hello

have you tried with

Disabled = "#{!}" "{Bindings.Execute.Enabled and (! lOVManagedBean.initiator)} '.

Try with single & or AND or and

Advanced tips

Here are some other tips to make the most of your research. You can get fancy by entering in a way search terms and using special characters to limit or expand your search results:

Action Description Example of

Search for content that has certain words, but not necessarily all the words in the order This is the simplest search. Simply enter your search terms. This example finds the content with the words sync, iPhoneand iTunes. sync iPhone iTunes

Search for content with some words in a certain order. To search for a specific phrase, place your phrase with quotation marks. Research will attempt to find the content with these words in order that their joint. He'll find any other content that contains only those words. ««Sync to iPhone»»

Search for content with words that have letters in them.
Use 'wildcards' to search for parts of words. Wildcards are special characters (*) that you include in your search terms...

Multiple generic character represents a number any character. For example, to search for sync, synchronized, or synchronization, you can use this search.
Sync *.

You can also use the wildcard character in the middle of a term. Note: You cannot use a symbol {0} or {1} as the first character of a search.

iP * d

Search for content with similar terms that you enter
"Fuzzy" searches return results that exactly match your search and the results terms that are nearby. For example, if you want to search for a word that is similar to the synchronization, add a tilde (~) to your search term. This research will correspond to terms such as sync, synchronizationand synck.
Sync ~.

Search for content in which some words are close to each other. To search for the words sync and the iPhone within five words of each other, enter a search like this phrase. "synchronize iPhone" ~ 5

Boost content with some words up in the list of results Boosting a search term gives it more weight in the list of results. For example, if you search for iPhone iTunes sync you might get results of synchronization with iTunes, but not necessarily to sync your iPhone with iTunes. In this case, use a caret (^) and a number to tell the search engine for the word "iPhone" of heavier weight. sync iTunes iPhone ^ 4

You can also push expressions that use a higher number, more to stimulate it. For example, if the stimulus a word in 3 still returns too many results, you can increase the value of the boost to 6.
'"iPhone sync" ' ^ 3 iTunes

"" sync iPhone"" ^ 6 iTunes

Search content to this word OR that Word; this word AND that Word. Using Boolean operators, you can combine terms by using AND, +, OR, NOT and -. ALL uppercase to distinguish these terms of the normal words.

The ORoperator links two terms and find content matching if or the other term exist in the content. You can also use two lines | instead of the word OR. To search the user tips that contain "iPhone sync" or "iTunes sync" use the query in the first two examples.

OR is the default mode to search terms together, even if we let him. The third example is equivalent to the two best examples.

"" sync iPhone"" GOLD "iTunes sync.

««Sync to iPhone»» | "iTunes sync.

"" sync iPhone"" "iTunes sync.

The operator AND , says that the search should return content in which all search terms are present. Note that you can also use the symbol & & in place of the word AND. Looking for advice about using that contain the "iPhone sync" and "iTunes sync" uses a search as in this example.

"" synchronize iPhone' "AND"iTunes sync.

'"synchronize iPhone' ' & & 'iTunes sync.

You can get fancy by grouping Boolean expressions using parentheses. For example, to get results on the different types of synchronization, try this example.

(iPhone iTunes music OR gold) AND sync Search of the content which is not having some words. The NOT operator excludes items that contain the term after NOT. You can also use the symbol ! in the place of the word NOT. To search for content that contains "iTunes sync" but not "sync music" uses something like in this example.

"" sync iPhone"" NOT "iTunes sync.

""sync iPhone "! "iTunes sync.

You must use the operator NOT with several terms. The example on the right will return no search results. NOT ""iPhone sync" Search for content in a particular place, such as the text of the topic or accessories. You can find something by looking at only part of the content. Type the name of the component contained by a colon after, then the text you want to search for. You can refine your search on the subject, body or tags. Here is an example that only searches for the word "sync" in the subject (title) of the content. Subject: sync Include special characters in your search phrase.

To include some special characters (illustrated right) in a search expression, you use a special "escape" character that tells the search engine to treat the special characters like the others.

+ & - & | ! ( ) { } [ ] ^ " ~ * ? \ To escape these characters, put a backslash (\) before the character. For example, to search for some (1 + 1) - 2, that has special characters (,), + and -, use this query. \(1\+1\)\-2

How to define the result of a call sequence of pass/fail

Hi all

in my application, I have a pass/fail with the adapter of the test sequence. The Source of data for the stage is Step.Result.PassFail.

Is it possible to tell the appellant (the stage of appeal for success/failure sequence) the result within the sequence? I've experimented with the RunState.Caller, but did not find any property that applies to the PassFail result.

Madottati

This link is not very useful and, in my view, is not the right solution for you.

It makes not sense why you need to change the Step.Result.PassFail inside your sequence. It is not evaluated until after that sequence is returned to the caller. So why not just pass back a parameter and and set the Step.Result.PassFail parameter. I've attached a picture that shows.

However, if it is essential that you change in the subsequence Fail pass then use this expression:

RunState.Caller.Step.Result.PassFail = here, a Boolean expression

It won't evaluate at time of publishing, but will work during runtime.

The reason why you use Pass/Fail card combination and sequence is to create a modularized test. Let's say you need to call several code modules in order to obtain pass/fail status. Think of it as a function or a Subvi. It just creates a clean, maintainable code.

Hope this helps,

VI quadrature encoder does not work after programming of FPGA

I'm rather new on the MyRIO, and I work on the motor of the MyRIO and read control in a quadrature encoder at the same time. Programmed individually, the two pieces of work at Marvel, but once I have combine them and try programming, control of motors not to not work signals, but the reader encoder does not work. I use the Express VI for the LabVIEW quadrature encoder reader, and I produce four stepper motors signals using FPGA.

It seems as if the encoder is disabled when I program the FPGA with my code, because if I have two parallel loops, one for the reader encoder and the control of step motors, if I stop the loop of step motors, the encoder works immediately.

Is there something simple that I'm missing? Any suggestions would be greatly appreciated!

Thank you

Enan

I realize now that my last answer could have been confused and not useful to someone else who may come across the same problems later.

Here is how I solved the problem I've had:

I had to derive Boolean expressions for an encoder quadrature (essentially to create my own) and then used the outputs (UP, DOWN) to increment/decrement a counter using the conditional statements. Then, I stored the value of direction in a flip flop implemented using two conditional statements of T/F in series and connected to a shift on the edge of the loop register.

It was all able to be implemented in a single cycle timed Loop, and then I managed to place in the same loop that I used to control stepper motor.

In this way, I could have a VI collected in a Bitfile and could be programmed to the FPGA.

Hope this is clearer!

multiple in a single frame case

Hello

I want to achieve such a function as follows in LabVIEW

If (1<><><><>

I = I ++ ;

else if (9<><><><>

I = I;

on the other

I = I;

I tried to combine boolean several together, but it turns out be a huge "building", please someone here help me, thank you!

You can have a case within a case structure structure. Thus, the box structure located in the wrong box of the outermost case structure would be equivalent to the part of the code ElseIf. It is not so complicated to install. In your case, because the code inside each case is a simple calculation just passing on the data or change it, a few select statements would work as well.

Where things are a bit more complicated is the assessment of your Boolean expressions since they consist of multiple comparisons related to the set. But it's not that bad, as you have just about build Boolean logic using the primitives LabVIEW provides. And since you have 4 conditions that all must be fulfilled for one of the Boolean expressions to be true, you can use the compound arithmetic node (available on digital and Boolean palettes) for fashion AND to combine several conditions.

Give it a try, and then if you get stuck, post your VI and we can help you improve it.

Sending of LabVIEW 8-bit unsigned integers

Hello

I send a bytestream of the pixel values in LabVIEW to a C program through TCP connection. I was wondering if this code really sends uint8 data or not, because when I read the data with a console in C application, 3/4 values are zero, as shown in the image below:

and then, when I pass the Boolean expression to send a 32-bit unsigned integer values, only 1/4 values are values null instead. This block is really send uint8 values? :

The VI is uploadet.

In fact, you always sending 32 bits, because your cast to this type 8-bit data (see red dots).

You perform the conversion to string within the structure of the case, something like this:

Andrey.

one of the three conditions, return true

I just saw the GOLD (Boolean Express) where if one of the TWO conditions, then return true to stop the labview.

Y does it have that provides all Boolean Express if one of THREE conditions met, return true?

With above document XML stored as varchar2 (4000) in 12.1.0.2.0, how can I retrieve and display the relevant information(sql_id,session_id,plan_hash,duration,read_bytes) based on the place where condition to filter on any node. For example.

select * from (
SELECT EXTRACT (xmltype.createxml (a.report_summary), '//stats/stat[2]/text()').getstringval () AS elap_time from dba_hist_reports a WHERE component_name = 'sqlmonitor'
)
where elap_time > 100000000
/

Here, I try to get sql_id, sql_exec_id, duration and other information stored in the xml document by applying the where on elapsed_time condition. But to do this, I must write the part EXTRACT for all nodes in the inline view which seems like very bad way of writing of XML query. Is there an easy way to get all the information of nodes so that I can freely apply node whatever, I want in the WHERE condition to filter the records? No better way to write the code then the code below?

Don't know why, but it pays just 1 or 0. Even in your case his statement just 0 or 1 for all X 2 columns table.

I guess I do something wrong in declaring XPATH for X 2 table but not able to find what it is.

It makes account 0 or 1 because path expressions are bad.

"For example: ' @name ="duration"

This is a Boolean expression, not a step of XPath and so gets evaluated as such, which gives 0/1 for false/true values.

What you need, it is something like this:
