How to take data between two rising edge

I would like to take waveform between two rising/falling edeg, I am using NI5102 VB6.0 with two input one is analog signal and the other is trigger input, start to read input signal when first trigger(rising/falling edge) and stop it by second trigger(rising/falling edge).
I have try to using counter CWcounter1.MeasurementType=... but the measurement tyep is not support my hardware.
How to count two trigger to read signal??

Hi,
I looked more into your issue. Couple of questions. What are you using the counter for? Are generating sample clock for digitizer using counter?
I am not sure why you need start trigger your application. But here is a solution I propose.
Use reference trigger as triggering option and then set reference position as 0% (this will set pre-trigger samples to zero).
Then perform multiple record acquisition. The advantage of using multi-record acquisition is that for every trigger, digitizer will acquire a record. Then you can fetch this data.
So, whenever there is a trigger ... you acquire a record which can hold data for 8.3ms.
If you have number of records greater than memory size of the digitizer, then there is an attribute NISCOPE_ATTR_ALLOW_MORE_RECORDS_THAN_MEMORY, setting this to true will allow you to have number of records greater than the memory size of the digitizer.
You can specify number of number of records using NISCOPE_ATTR_HORZ_NUM_RECORDS
Use NISCOPE_ATTR_FETCH_RECORD_NUMBER to acquire current record by linking it to index i of for loop.
Use NISCOPE_ATTR_FETCH_NUM_RECORDS to acquire only one record when trigger occurs.
So,
1) Set the program for multi-record acquisition
2) Once trigger occurs, acquire current record using NISCOPE_ATTR_FETCH_RECORD_NUMBER and acquire only one record per trigger using NISCOPE_ATTR_FETCH_NUM_RECORDS.
If not, you are not sampling at higher rates and you can also use a DAQ card with counter to acquire data using retriggerable acquisition.
Let me know if this helps you.

How to pass data between two internal sessions using ABAP memory?

Hi,
How to pass data between two internal sessions using ABAP memory?
It would be fine if you could explain with an example.
And also let me clear about the data passing between two main sessions and two external sessions with specific examples.
Thanks.

Hi ,
check the example.
Reading Data Objects from Memory
To read data objects from ABAP memory into an ABAP program, use the following statement:
Syntax
IMPORT <f1> [TO <g 1>] <f 2> [TO <g 2>] ... FROM MEMORY ID <key>.
This statement reads the data objects specified in the list from a cluster in memory. If you do not use the TO <g i > option, the data object <f i > in memory is assigned to the data object in the program with the same name. If you do use the option, the data object <f i > is read from memory into the field <g i >. The name <key> identifies the cluster in memory. It may be up to 32 characters long.
You do not have to read all of the objects stored under a particular name <key>. You can restrict the number of objects by specifying their names. If the memory does not contain any objects under the name <key>, SY-SUBRC is set to 4. If, on the other hand, there is a data cluster in memory with the name <key>, SY-SUBRC is always 0, regardless of whether it contained the data object <f i >. If the cluster does not contain the data object <f i >, the target field remains unchanged.
In this statement, the system does not check whether the structure of the object in memory is compatible with the structure into which you are reading it. The data is transported bit by bit. If the structures are incompatible, the data in the target field may be incorrect.
PROGRAM SAPMZTS1.
DATA TEXT1(10) VALUE 'Exporting'.
DATA ITAB LIKE SBOOK OCCURS 10 WITH HEADER LINE.
DO 5 TIMES.
ITAB-BOOKID = 100 + SY-INDEX.
APPEND ITAB.
ENDDO.
EXPORT TEXT1
TEXT2 FROM 'Literal'
TO MEMORY ID 'text'.
EXPORT ITAB
TO MEMORY ID 'table'.
SUBMIT SAPMZTS2 AND RETURN.
SUBMIT SAPMZTS3.
The first part of this program is the same as the example in the section Saving Data Objects in Memory. In the example, the programs SAPMZTS1 and SAPMZTS2 are called using SUBMIT. You can create and maintain the programs called using the SUBMIT statement by double-clicking their names in the statement. For further information about the SUBMIT statement, refer to Calling Executable Programs (Reports)
Example for SAPMZTS2:
PROGRAM SAPMZTS2.
DATA: TEXT1(10),
TEXT3 LIKE TEXT1 VALUE 'Initial'.
IMPORT TEXT3 FROM MEMORY ID 'text'.
WRITE: / SY-SUBRC, TEXT3.
IMPORT TEXT2 TO TEXT1 FROM MEMORY ID 'text'.
WRITE: / SY-SUBRC, TEXT1.
Example for SAPMZTS3:
PROGRAM SAPMZTS3.
DATA JTAB LIKE SBOOK OCCURS 10 WITH HEADER LINE.
IMPORT ITAB TO JTAB FROM MEMORY ID 'table'.
LOOP AT JTAB.
WRITE / JTAB-BOOKID.
ENDLOOP.
The output is displayed on two successive screens. It looks like this:
and
The program SAPMZTS2 attempts to read a data object TEXT3 from the data cluster "text", which does not exist. TEXT3 therefore remains unchanged. The existing data object TEXT2 is placed in TEXT1. In both cases, SY-SUBRC is 0, since the cluster "text" contains data.
The program SAPMZTS3 reads the internal table ITAB from the cluster "table" into the internal table JTAB. Both tables have the same structure, namely that of the ABAP Dictionary table SBOOK.

How to separate data between two colons

Hi,
how to separate data between two colons?
ex: 'ABC:1234:1-ss-2:0:0:0:0-DEF:5678:0:0:0:0'
how to access these 1234, 5678 and 1-ss-2 ?
there may be any string.
please help

Hi,
The string 'ABC:1234:1-ss-2:0:0:0:0-DEF:5678:0:0:0:0' contains 11 colons, and 10 sub-strings that are between colons. How do you distinguish the ones you want,
(1) 1234
(7) 5678
(2) 1-ss-2
from the ones you don't want
(3) 0
(4) 0
(5) 0
(6) 0-DEF
(8) 0
(9) 0
(10) 0
Anyhow, in Oracle 10 (and up) you can easily get the n-th item from a :-delimited list by saying:
REGEXP_SUBSTR ( txt
              , '[^:]+
              , 1
              , n
              )First use REGEXP_REPLACE to remove anything before the first colon and anything after the last one.

How to compare data between two tables?

Hi,
My team is trying to develop a SAP data migration tool (DMT) using ABAP.
One of the functionalities in the DMT is to validate the data in the staging area against the loaded SAP data.
The tables in the stagin area are customer tables (i.e. user-defined tables starting with Y, Z).
How do I compare the data in the staging area against data that are loaded into SAP tables? Are there some built-in SAP functions to do this? Or, are there some better ways of doing this (e.g. instead of comparing against data in the SAP tables, we compare with some INTERNAL tables)?
Any help would be greatly appreciated, thanks!

Hi Kian,
Use <b>SCMP</b> transaction to compare data between two tables and you can not use this for comparing internal tables.
Thanks,

Oracle-java How to fetch data between two Timestamps

hai...
I am using a program where i have to get all the data entered into oracle db between two dates
(The first date being manually inputted and the second one is inputdate-24hrs) . The code is as follows....
Connection c = null;
PreparedStatement pStmt = null;
ResultSet rs = null;
try
//eg String dt=14/03/2007, hr=03, min=27, ampm=am
     DateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy");
     DateFormat outForm = new SimpleDateFormat("yyyy/MM/dd");
     Calendar cl = Calendar.getInstance();
     Date inDate = new Date();
     inDate = dateFormat.parse(dt);
     cl.setTimeInMillis(inDate.getTime());
     cl.add(Calendar.DAY_OF_MONTH, -1);
     String str1 = outForm.format(new Date(cl.getTimeInMillis()));
     String str2 = outForm.format(dateFormat.parse(dt));
     System.out.println("Changed date = "+str1);
     System.out.println("Original date = "+str2);
     String toStr = str2+" "+hr+":"+min+" "+ampm.toUpperCase();
     String fromStr = str1+" "+hr+":"+min+" "+ampm.toUpperCase();
     System.out.println("From date = "+fromStr);
     System.out.println("To date = "+toStr);
// For example, if u r confused, From date = 2007/03/14 03:27 AM
//                            To date = 2007/03/13 03:27 AM

     pStmt.setString(1, accountId);
     pStmt.setString(2, fromStr);
     pStmt.setString(3, toStr);
     rs = pStmt.executeQuery();
}The problem is that i am not getting results as expected
Can anyone point out if there is something wrong in the logic or in the program....

But how to make that string to the Timestamp object.
I tried this way but failed !!!
// Eg :fromStr = 2007/03/14 03:27 AM
//       toStr= 2007/03/13 03:27 AM
     SimpleDateFormat sdfOutput = new SimpleDateFormat("yyyy/MM/dd hh:mm a");
     Date fromDate = sdfOutput.parse(fromStr);
     Date toDate = sdfOutput.parse(toStr);
SELECT TRANS_ID, TO_CHAR(CONCAT('Rs.',TRANS_VALUE)) AS TRANS_VALUE, " +
               "TO_CHAR(TRANS_DATE,'DD/MM/YYYY HH:MM AM') AS TRANS_DATE, ACCOUNT_ID, " +
               "TO_CHAR(CREATED_DATE,'DD/MM/YYYY HH:MM AM') AS CREATED_DATE, CREATED_BY, " +
               "INSTR_D_BANK_CD FROM TRANS_TB WHERE " +
               "ACCOUNT_ID=? AND TRANS_DATE BETWEEN ? AND ? ;

     pStmt.setString(1, accountId);
     pStmt.setString(2, fromDate);
     pStmt.setString(3, toDate);
     rs = pStmt.executeQuery();
     I think there is problem in both String-Date conversion and in the query.....

How to exchange data between two web application (servlet)

Hello, all,
I have two servlets: SerlvetA and ServletB, they are deployed as web appA and appB in the same web container(tomcat)
How ServletA exchange data with ServletB?
I have tried follow methods:
1) appA and appB could not share HttpSession, so I could not transfer data through session
2) I write a new sigleton java class called AppBroker, servletA get AppBroker's instance, and set some data into the it. ServletB could not get the same instance of the AppBroker, because the appA and appB use different class loader.
tell me how to?

thanks reply, but
1. static class can not solve the problem, it is same
as my sigleton class method, as different web app use
different class loaderhmm... at least in tomcat this seems not be true since i can use static classes in one webapp that are available in another web app on the same host/servlet runner.
Maybe if you build your own classloader than the "scope" of the static class is limited to that classloader (for my understanding this shouldn't be the case since i think it depends on the instance of the jvm and not of the classloader..?!).
2. rmi and object serialization are too expensive!
I am working on how to use jndi to solve this problem.
And I think this maybe a Sevlet specification's
shortcoming: maybe a Local Method as EJB local
interface need been introduced into servlet spec.
could you suggestion other methods?none at the moment. i guess the basic methods are listed.
Maybe there's just one left, a really ugly one. Depending on what kind of data and how often you have to exchange you could think of building a file-based queue, i.e. a dir where you drop files in an read out from the other web app (maybe based on a file/directory listener). But this would only be an appropriate way to go for kind of email and messaging systems i guess...

I'd probably use a database for this, if there's any quantity of data involved here. Import from Excel into {SQLite, MySQL, PostgreSQL, FileMaker, maybe Core Data}, or pick your preferred key-value store, keep your data in the database, then export or (via ODBC/JDBC) then access live database data from within the spreadsheets.
Alternatively and if you're looking at small quantities of data (say, less than 10,000 entries, or less than a thousand depending on the language), then just use whatever passes for a key-value store in your preferred scripting language {Python, bash, Lua, or maybe php, AppleScript or Java} and use that. Export Excel to CSV {gag} or XML, then load that into Python and process as needed, then write out CSV {gag} or XML.
AppleScript is a scripting language for GUI applications, and also useful for processing events. If you're not doing that sort of stuff, then there can be other choices, and other choices can often have extensive frameworks and libraries for common tasks.
Sooner or later, most everybody runs into a wall when using a spreadsheet... Various folks have encountered those limits and have migrated from spreadsheets to FileMaker databases, and now use a database as the central store for their operations — and that's the other issue that can arise with spreadsheets... Where's the canonical data?

How to compare dates between two items

Hello all,
I am trying to compare dates in two items.
The first item is a computation P45_PAGE_LOADED_TIME
select sysdate from dual;
This essentially keeps track of when the user opened the form. They are accessing data that may become obsolete while they are in the form.
So we have a dynamic action that finds the last_update date from a table. This field is of type date. It is placed in a text field called P45_STATUS.
We then have a notification which we want to fire when P45_PAGE_LOADED_TIME is before P45_STATUS. We tried the following condition
declare
least_date date;
begin
SELECT LEAST(TO_DATE(:P45_STATUS),TO_DATE(:P45_PAGE_LOADED_TIME)) into least_date
from dual;
if least_date = to_date(:P45_STATUS) then
return false;
else
return true;
end if;
end;
Any guidance would be most appreciated.
Thanks

Maybe your better off putting your anonymous block into a plsql function.
A function that you can test. If it works in plsql then you must call it in APEX.
I kinda get a headache when I see that least, to_date, to_date query (although I've seen worse :p)
Make it like:
create or replace function fun_least_date(in_status in varchar2,
                                                           in_page_loaded_time varchar2) return boolean
is
l_status date;
l_page_loaded_time date;
least_date date;
l_return boolean;
begin
l_status := to_date(in_status, 'FORMAT MASK!!!');
l_page_loaded_time := to_date(in_page_loaded_time, 'FORMAT MASK!!!!');
least_date := least(l_status, l_page_loaded_time);
if least_date = l_status then
    l_return := false;
else
    l_return := true;
end if;
return l_return
end fun_least_date;If your sure that your function is correct then use it as a condition for your dynamic action.
Regards
Nico
ps: I haven't tested that function. Be aware that you most correctly enter the format mask you use in APEX. Also before APEX may know about these variables you should set a dynamic action on your items to always submit their value to the server when they change!!!

How to move data between two similar tables?

Hi All,
I have two tables with almost the same columns. Table A has 50 columns, Table B has 51 columns, which are defined exactly the same except one more column as LOAD_TIME.
Is there any easy way for me to move the data from Table A to B? the Extra column LOAD_TIME will be set as current system time. All I want is to avoid list all 50 column names. The following SQL has error ORA-00923 error.
INSERT INTO TB_B
SELECT *, sysdate from TB_A;
Thanks,

Thanks,You could create a view based on TB_A.
However i don't understand why you feel the need to avoid specifying the columns. That's a better way to code.
Granted, i also don't understand why you'd have 2 copies of the same data, the only differentiation being when you copied the data from the source to the redundant table.

How to copy data between two tables row by row

Hi All,
I have three tables TableA and TableB and TableC
I wanted to write a stored procedure to copy data row by row from TableA to TableB and then update TableC by replacing any record that has the old id (before copying) to the new id after copying the data.
here is the steps
iterate throw all the rows in tableA ( probably with a foreach)
in each iteration we will do the following:
Get current ID (identity) for each record in TableA ( will call it @oldID)
Insert the row in TableB
Get the new ID for the row from TableB will call it (@NewID)
find rows in tableC that has the (@oldID)
replace all ids in tableC with @oldID to @NewID
Thanks in advance

0
TableA and TableB are identical they should have the same columns
TableC columns will be ( ID, TableA_ID , Notes)

How can I copy large amount of data between two HD ?

How can I share data between two forms on different lists

Using a custom content type, I created two lists that I want to share the same data - one is a calendar. Our employees complete a form from the "Out of Office Request" list that has workflow functionality that sends an email to that person's
manager. If the manager approves the request, the item automatically populates the "Out of Office Calendar." The problem is that the only information from the request list that populates the calendar is the Title field and date/time fields.
I need the manager name in order to create a view for each manager.
How can I connect the other information in the request list to the calendar list. It seems to me that if the title and date fields carry over the information, there should be a way to connect the other information. I'm using Designer.
I've tried to connect the two lists' webparts with the wizard, but when I get to the page that maps the two lists, there are no column names and the "Next >" button is grayed out. This seems like the logical place to connect the two lists,
but it isn't working.

Hi,
According to your post, my understanding is that you wanted share data between two forms on different lists.
To show external information on the calendar event, there are two methods: Calculated column, workflow. You can refer to:
A Simple Guide to Show More Information on a Calendar Event
I recommend to use workflow to achieve what you want. But you need to create a people column to display the manager.
You can create a workflow associated to the "Out of Office Request" list, add action to Start Approve Process. If the manager approves the request, you can create a item in the calendar, and then update the people column and the title column.
Then the calendar will display the Title, date/time and the manager.
To create a view for each manager, you need to modify the Filter. You can use the people column is equal to the manager name or the Title contains the manager name.
Thank you for your understanding.

How do I perform a trigger that collect the data for every rising edge continuously and then automatically put the data in a .xls file??

I need to collect the data for every rising edge a trigger perfoms. So far I could collect the data but it seems that it only collect the data in the start of triggering, but not continuously. I also want to put the data in an excel spreadsheet and automatically add new set of data when the next rising edge occur. Please help.
thanks a lot.

LabWindows/CVI actually ships with a comprehensive set of examples for just about every area of programming you can use it in, including triggered analog data acquisition and ActiveX control of Microsoft Excel for data logging. Go to the following two directories on your computer to find respective examples for the two areas you are inquiring about:
1) C:\MeasurementStudio\CVI\samples\DAQ\Ai\DAQsingleBufExtTrig.PRJ
2) C:\MeasurementStudio\CVI\samples\activex\excel\excel2000dem.prj
Just make sure to study the examples carefully so that you fully understand the processes followed for triggered analog acquisition and the process of launching an ActiveX automation server for control, and then you should be able to merge the concepts shown in both of the example
s to make the application you desire.

How can I get extract the data between two cursors on an XY graph

How can I get extract the data between two cursors on an XY graph

Well, you say xy graph, so this might be a more complicated problem.
For a waveform graph it's trivial. Simply get the two cursor indices (property: cursor index) and apply them to array subset of the data. Is that all you need?
Here's how the above code would look like. using cursor.index instead of cursor.x elimnates the need to include scaling information.
For an xy graph, there could be multiple segments (e.g. imagine a spiral that passes the desired x range multiple times from both sides). This would neeed significantly more code for a general solution.
