Search for the string in the string table and see the following value in the line
Hi, I'm new I have LV and I do a Vi that read worksheet values and generates 2d channels of the same spreadsheet table. For the moment everything I need is a function that find specyfic string in this table and show the next value in a line. As:
Table:
a; b
c; d
f; g
example: find the 'c '.
VI shoud show "d".
Concerning
Not a bad homework problem. Do it with pencil and paper. Write your table and pretend you're the computer. What you want to do (step by step)? What questions do you have?
Now that the translation a bit to computers. You mentioned that the data is in an array of strings. What structures (LabVIEW) work with tables? [Do you know how to work with tables? [Otherwise, review some of LabVIEW Tutorial material - see top right of the first page of the Forum]. What do you know about channels? What questions you need to ask questions on the channels? What do you know about string functions?
Watch these things in some LabVIEW code, 'feed' some data and see what he does. If it seems to do things "unexplained", you can try to look at the block diagram to run by turning the performance highlight (and if you don't know what that means, use the help of LabVIEW and see the tutorials).

SQL query to search for the line that contains the identifier for each consecutive group
Hello
I'm on 11.2.0.3 Enterprise Edition.
I have a strange request here - do not know if this is possible without going to procedure...
Given these data of the sample:
create table test_status ( status varchar2(10), revision_id number, revision_timestamp timestamp); insert into test_status values ('PROPOSED', 1, systimestamp); insert into test_status values ('PROPOSED', 2, systimestamp); insert into test_status values ('PROPOSED', 3, systimestamp); insert into test_status values ('ACTIVE', 4, systimestamp); insert into test_status values ('ACTIVE', 5, systimestamp); insert into test_status values ('PROPOSED', 6, systimestamp); insert into test_status values ('PROPOSED', 7, systimestamp); insert into test_status values ('ACTIVE', 8, systimestamp); insert into test_status values ('ACTIVE', 9, systimestamp); insert into test_status values ('FINISHED', 10, systimestamp); insert into test_status values ('FINISHED', 11, systimestamp); insert into test_status values ('FINISHED', 12, systimestamp);
Gives me:
SQL> select * 2 from test_status 3 order by revision_id; STATUS REVISION_ID REVISION_TIMESTAMP ---------- ----------- ----------------------------- PROPOSED 1 25-SEP-14 04.49.47.954000 PM PROPOSED 2 25-SEP-14 04.49.47.962000 PM PROPOSED 3 25-SEP-14 04.49.47.966000 PM ACTIVE 4 25-SEP-14 04.49.47.969000 PM ACTIVE 5 25-SEP-14 04.49.47.972000 PM PROPOSED 6 25-SEP-14 04.49.47.976000 PM PROPOSED 7 25-SEP-14 04.49.47.979000 PM ACTIVE 8 25-SEP-14 04.49.47.982000 PM ACTIVE 9 25-SEP-14 04.49.47.987000 PM FINISHED 10 25-SEP-14 04.49.47.991000 PM FINISHED 11 25-SEP-14 04.49.47.996000 PM FINISHED 12 25-SEP-14 04.49.48.000000 PM 12 rows selected. ws selected.
I want to get this result:
STATUS REVISION_ID REVISION_TIMESTAMP ---------- ----------- ---------------------------- PROPOSED 3 25-SEP-14 04.49.47.966000 PM ACTIVE 5 25-SEP-14 04.49.47.972000 PM PROPOSED 7 25-SEP-14 04.49.47.979000 PM ACTIVE 9 25-SEP-14 04.49.47.987000 PM FINISHED 12 25-SEP-14 04.49.48.000000 PM
Then query the table ordered by Revision_Id, I would get the line containing the highest revision for each consecutive group of status values. I am able to get the line containing the highest revision for each separate status, value, but I can't deal with the scenario where a state value reappears later. In the case of the real world, it is a workflow and I need to take into account the fact that an element through the workflow may be redirected to the back front she proceeds forward again.
Hope it makes sense.
Thank you

Searching for a string in an array (complex) token value
Look at this example:
with tableA as

Union of all the
Select 143, 'GO', 'Development','DAV. ID; FOX; RON; GIL; BERT; FID; UC;' of the double
Union of all the
Select 476, 'FON', 'REST', "UC; DAV; "the double
Union of all the
Select 2685, "ELAB", "REN", "IDF;" the double
Union of all the
Select 2688, "REN", null, "RTM"; the double
)
,
tableB as
(
Select 'GOOG' soc, 'DAV' double modul
Union of all the
Select 'GOOG', 'ID' from dual
Union of all the
Select 'GOOG', 'FOX' of the double
Union of all the
Select "GOOG", "RTM" of the double

)
Select * from tableA
/ * where at least a token in the field "modul" exist in (select modul in tableB where soc = "GOOG") * /.
connect name = sub
Start with nn = 2688
My goal is to find a way to determine if a token (value separated by ';') tableA.modul is present in the tableB.modul where soc = 'GOOG '.
The selection of tableA must be in this form, with the connection by.
Expected the result of the example above should be 3 drives (nn = 2688, nn = 143, nn = 1)
Solution 1: extensive use of regular expressions?
Solution 2: count the lines using intersect?
I did not...

On Windows XP, there is a search function to search for a string in any kind of files on your computer. You are looking for a specific name was easy, if you fogort what kind of file, this name occurred in or what it was named.
On Windows 7 it only allows searching for a name of a file. How to search for strings in file names? 29/12/12 Paul Figueroa
Oh, what you want is the content property.
content: ~ = Figueroa
[Update: apparently special search symbols such as ~ = do not work with the content when property indexed research places, but work during the search in unindexed locations.]
I should mention that Windows 7 Search is not case sensitive, so it makes no difference to try to find upper or lower case letters. In addition, Windows 7 Search is not able to search the contents of files that have no file extension. There is also a weird question having to watch in Indexing Options to determine which file extensions are defined for content, research, where you have a type of unusual file that is not defined for the content of the search.

BY SPECIFYING THE NUMBER OF IDENTICAL CHARACTERS WHEN SEARCHING FOR A STRING
Hey everybody,
built-in indexOf() finds a character "." in the string "1.2.3." If value == 1.
It looks nothing if the value == 0 or 2 or a number greater than 2.
var txt:String = '1.2.3.';
var: output string = String (this);
If (txt.indexOf(".") == 1)
{
trace (output); [object MainTimeline]
}
The must be a simple method to specify the number of characters "." When you search for the string "1.2.3.".
For example, if there are 2 characters "." in the string "1.2.", then run it through a statement but if contains no 2 characters "." then do nothing.
There is a built-in function called contains , but it is mainly used in XML.
indexOf() resembles codes javascript unstable, one of these framework which unixers hatred.
You don't have to use regular expressions to determine how many points is in the string. Use of split and read the length:
var txt:String = '1.2.3.';
trace (txt. Split("."). (length);

Search for the nearest value table
IM wondering if its possible to find a 1 d table worth, if it is not found, then find the nearest match. IM using the 'double' data type and I need at least an accuracy of 4 decimal point in the research.
For now, im rounding decimal values to the nearest integers from you, but it is not effective at all. Im getting a lot of unwanted split in the plot. I need to be able to search for the decimal points. I found this function "About Equals.VI" starting from a previous thread. Even that uses the concept of the rounding.
I enclose 3 screws "0.8 & 0.4.VI" are that I created, rounding decimals nearest digit.
The "approximately equal" is the one I found online.
The 3rd is I try to mess with what I can find as close a match.
Y at - it a trick to work around this problem?
Thank you
Eureka
This VI uses the first type of step 3 in your data. Since you said that you can get the data, you can drop the in VI.
At the end where I calculate the slope, you can use a linear adjustment if you have full or professional LabVIEW.

Search for the text value data store
Hello, I have a PDO of data to store, and I would like to search for a text value in a quantity of measure. In each of my test series, there is a quantity of measure with the name TCNAME and stores the cell name of test in the string format. I would like to get all the TCNAMEs that contain "TC4" for example. Currently, I have to load TCNAME in the portal and display it in an array of string.
Any ideas how I can do this?
I assume you are using a PUMA testbed that stores this kind of goods on a unique value chain chains.
There is no direct search method, so I guess that a script is the only solution we can offer.
Datafinder you can search for the minimum and maximum of a channel. That would be too much work in the store of ASAM.
"PDO / cpp"
protected tcnameMQs: set tcnameMQs = store. GetElementList ("MeasurementQuantity", "name = TCNAME", true)
protected tcnameMQ: for each tcnameMQ in tcnameMQs
MsgBox tcnameMq.References ("local_columns"). Elements (1). Properties ("values"). Value
Next' AOP5 / Corba
protected tcnameLCs: set tcnameLCs = store. GetElementList ("LocalColumn", "measurement_quantity.name = TCNAME", true)
protected tcnameLC: for each tcnameLC in tcnameLCs
MsgBox tcnameLC.Properties ("values"). Value
Next
I have added the example which should be the shortest path from my point of view. In AOP5, you can search LocalColumn and spend BA which is less overhead.
It is perhaps a good idea to post-processing of the data base and crush the decription "Test name" by
"The test cell name == NAME. You can search not post-processed by Searchin' for.
protected tcnameMQs: set tcnameMQs = store. GetElementList ("MeasurementQuantity", "description = name of the test cell", true)
protected tcnameMQ: for each tcnameMQ in tcnameMQs
tcnameMQ.Properties ("description"). Value = "name of the test cell is" & tcnameMq.References ("local_columns"). Elements (1). Properties ("values"). Value
Next
Store.SaveThereafter, you would be able to search for it.

Search for the last occurrence of a substring
How to search for the last occurrence of a substring in a string? In more detail: I have the array with the names of files, and I want to split the file name extension in a separate column. The name extension doesn't have a fixed rate with (can be 'c', "" jpg"or"mpeg", etc.), and names of files themselves can contain points (if this is possible:"recording.of.last.meeting.mpeg".)
So the only way to extract the name extension is to look for the last appearance of a dowry and split on everything after the last point. How can I do this? I worked with a sybase database before and there was a string function to search for the right of the string. Is there something similar in Oracle?If you're on 10g, you can
with t as ( select 'recording.of.last.meeting.mpeg' file_name from dual ) select regexp_replace(file_name,'^.+\.') fiel_extension from t

Hi jafrin.michel,
Thanks for posting in the Microsoft community.
Before you start the troubleshooting steps, I need the information required.
What version of the windows operating system do you use?
Method 1:
If you are using windows 7, I suggest to perform a disk cleanup and verify.

Method 2:
If you want to move the pagefile.sys to another drive, follow the steps and check out them.
Follow these steps to move the pagefile.sys to C: drive on D: drive (if you have the drive D :).
1, write click on my computer and select Properties.
2, click on the Advanced tab.
3, click settings under performance menu.
4, click on the Advanced tab and click on change.
5, select letter (C :) and "BOLD" No pagefile then click on Set. )
6, if you want to configure pagefile.sys in, select drive D: drive letter D: and "BOLD" in the custom size or the size of the system managed , then click on Set. It displays a pop-up message click OK.
7, again click apply and OK OK.
8, the system you will be asked to reboot, click on Yes.
9, after rebooting the system, you can see the pagefile.sys will be moved to D:

"Can not open AsIO.sys (2)" I get this message when I log in after a reboot. I have search for the file, but can't find it with the research or the command prompt. What do do in this file, and can be created and put into the appropriate folder?
Hi Jack,
This driver belongs to AsIO.sys Asus Probe. Try to uninstall Asus Probe and if you need, install again. If this does not help, uninstall Asus Probe and other tools of control such as Speedfan. Open the registry (regedit.exe) editor and search for AsIO.sys and remove all the entries that you can find.

What is the query to search for the user of the application in the sql command?
I tried the query belowselect app_user from dual;
Thank you.app_user invalid identifier
Hello skud,
The following SQL statement will give you the APP_USER which is an environmental variable in the APEX:SELECT v('APP_USER') FROM DUAL;
See if it works. As I used the syntax given in the triggers to record audit trail above and it works fine.

Look for the lines selected on a tabular presentation
Hello guys and girls,
I have a small problem trying to understand if/how I can check by pressing the "submit" button if there where no records selected in my tabular presentation.
To explain better: I have a selection list in which the user select an employee. On this choice, a tabular presentation appears with the own products for this employee.
The user must check at least one of the lines to go further.
If the user does not select all and always press the "submit" button you should see an error message saying: "there are no selected product."
What I was doing until now (stupid I suppose) was to create a Boolean as validation:
DECLARE
vRow directory;
BEGIN
BECAUSE me in 1... apex_application.g_f01. COUNTY
LOOP
vRow: = apex_application.g_f01 (i);
If vRow is NULL then
Returns false;
on the other
Returns true;
end if;
END LOOP;
END;
But does not work. If I have no active records it will say nothing and let me go. If I check something even record.
Help, please.
There must be something that I have no idea about.
Thank you very much.
Gabriel
Checkboxes only support values for the lines. For example, a loop on the table will always return true since vRow will never be NULL. In addition, a table with a number equal = 0 will not be locked during all, again don't generate no errors.
No loop, just check apex_application.g_f01. COUNTY. If it is 0, no checkboxes have been verified.
