Read a txt file, display a table of values, select a value to set min value for DAQMX

Hello everyone, I am having trouble with the following data importing. I want to do the following:
Open a txt file, have it be imported as a table. Allow the user in the GUI to select a value on the 2nd column, set that value as either min or max for a daqmx analog output. I'll attach the .txt file being used. I can add the code but I was basically using the read from text.vi example with no luck.

Thank you all, I have set up this input but I have a couple more questions. First now that I have the ability to have a mouse click to set a value, is it possible to have two events, such that the first sets a certain value and the second retains a different one?
In addition (im not sure if this would be ok to post here but for the sake of clarity and decluttering the forum I shall post it here) is it possible to switch from a constant voltage mode (in DAQMX analog output) to a waveform mode ( attacthed the binary waveform) all while maintaining a constant min value (untill updated from the table by user, which is also attached).
I have attachted a vi (Labview version 8.2) that I threw together today.
Thank you all,
DB

Uploading .txt file to z table

Hai Friends,
I want to upload a .txt file to Z table which contains around 27 fields. but .txt file contains data in two lines by as follows.
4.5 2.36 21.56 25 36.14 47.00 145.3 1247.6
10.2 4.6 23.5 589.1 20.1 45.6
Is it possible to upload the .txt file.

Hi,
It is possible to upload txt file to ztable. You need to write small program for that.
   Please see the example code below. Here from excel they are converting to internal table, use 'GUI_UPLOAD' to convert text file data to internal table and use this internal table to upload data into ztable. use MODIFY ZTABLE FROM TABLE ITAB.
Also maintain the internal table structure and structure of the ZTABLE should match.

Help reading a .txt file from the hard drive....

Hi guys,
Ok... I need to know how to read a .txt file from the hard drive... I have an example on how to read from a disk, but I don't have a disk drive. I could be confusing terminology, but I don't think I am. Here is the code I have for reading from a disk.. please let me know how I should change it to read from a hard drive.
Also, when the error pops up, it says that it can't read another .txt file that is not specified in the code... any ideas how that is occuring? Please advise.
import java.io.*;
public class TEST {
public static void main(String args[]) throws Exception{
FileReader fr = new FileReader("customer.txt");
BufferedReader bfr = new BufferedReader (fr);
String s;
while ((s=bfr.readLine())!= null){
System.out.println (s);
fr.close();
}

Ok... I need to know how to read a .txt file from the
hard drive... I have an example on how to read from a
disk, but I don't have a disk drive. I could be
confusing terminology, but I don't think I am. Here
is the code I have for reading from a disk.. please
let me know how I should change it to read from a
hard drive.The code will be the same, regardless of where the file is located. It's just the filename that will be different.
Also, when the error pops up, it says that it can't
read another .txt file that is not specified in the
code... any ideas how that is occuring? Please
advise.Probably becuase the class file (compiled version of the source code) is a different version to the source code, i.e. the source code hasn't been recompiled since the source code was changed.
How does this relate to EJBs?

Assistance in Reading a .txt file

I'm newbie on Java and I have a problem
I'm doing a homework on Systems and I need to read a .txt file [It would be on the same folder as the Java file].
The catch is that I have to read by Lines, Each Line could have as much as 3 words[tokens] as little as one.
I also have to read the characters on the words/tokens to identify if they are valid.
I have thought of 2 ways of doing this.
Reading ALL the line and dividing the words by the Spaces.
Or read the words by tokens and then having a flag to know when the line jumps.
Example of the text file:
ORG %011010
Et1 equ $ffFF
;Comentary # 1
dos LDAA @456
END
I hope I'm being clear.
Now, I'm not looking to have my homework done for me, but I am looking for some pointers.
I've tried the Scanner class but I just don't know the right methods I guess... I've also heard the Token StringTokenizer class works. But I have no clue.
Someone could give me pointers? which Class would be the right one and which methods?
I've been Struggling with this all week.
Help will be really appreciated.

I would use the Scanner class to read an entire line. If you don't know what methods to use then read the Java API and the explanation for each method of the Scanner class. Write some code to experiment and see what those methods do. Then when you have an entire line I would use String.split as StringTokenizer is/has been deprecated.

Dude, netiquette. Messages like "i need this now! Do it!" are really offensive and no one here is being payed to answer anyone's questions. We're here because we like to contribute to the community.
Anyway, in your case, just perform some search on how you could filter the files that are attached to the message. The sample module is just an example, you'll have to implement your own. Tips would be to query the filename of the attachments (or maybe content type) and for the ones which are not text, remove them.

Read a .txt file

I'm trying to find out how to read a .txt file and simply assign its contents to a variable. Is this possible?
[Edit] Right after posting I found this page which seems like it might be in the direction I want to go but I haven't checked it out completely yet: http://extendscript.blogspot.com/2009/06/read-tab-delimited-text-file.html
Just posting the link for future searchers or if anyone will tell me 'Hey! That's not what you're looking for!'

For anyone interested, the simplified answer for me was:
var fileToParse = File ('path');
fileToParse.open('r');
var dataToGet = fileToParse.readln();
fileToParse.close();
I only needed the one line, so thats why my example above is so simple.

How XI will read the .txt file

Experts,
i AM WORKING ON A FILE BAPI synchrounous scenario.
Sender will drop the required file on XI directory and XI will pull the file and map it with the BAPI u2013 and crate services entries in SAP SCM. If errors are encountered during the process they are returned to the client in a report or as erroneous file.
   *I have a .txt file( tab delimitted file) in the folowing structure
H                       NAME                        date            ***                 data_txt                         676869*

like this multiple entries, ll be getting .
Based on H ( indicator), Have to get the data. How will I do in XI file adapter? Please help me how should I design the file adapter so that It can read the .txt file.
I have created the sender data type similarly to the structure of BAPI.
Note; H indicates teh Header and D indicates teh sublines. Together it is called one service entry. Aagain Next 'H' indicates the strat of next service entry.
Thanks

Continiously read a txt file

Hello fellows,
is there a way to read a *.txt file continiously without doing the simple while loop wich burns all the CPU ??
This txt file is generated by another application that pick up messages from a pipe and register messages in the txt file.
As a final goal the messages read in the txt file will control other executions in the vi.
Attached files: vi in LabVIEW 8.0 and the txt file.
Attachments:
Zip.zip ‏6 KB

Thanks for your interest ! !
The process will be as follows:
1-an application reads text in a serveur pipe and write it into the txt file.
2-The LabVIEW vi reads in loop the txt file and sort out the txt value each time that's updated by the application running in parralel.
The goal is to synchronize the labview execution with the new messages arriving in the txt file.
Thanks for your suggestions on how can I continiously read the txt file and take an action in the vi each time the txt file is updated with new text.
See you...

How to read a txt file then insert them into db tables

Hi,
Please help me to solve this problem. This is what I need to do:
1. read a text file which holds the values to be inserted into some database tables. For example it holds ename, deptno, sal, dname for emp and dept tables. These are in a text file now.
2. Then I need to insert these data into db tables like emp and dept, and check if there are dups or voilate any constraints. The records to be inserted are usually > 100,000, so I am also looking for a fast way to do this.
3. This operation happens regularly, so I need to schedule the job. I know this can be done by using procedures and dbms_jobs.
Any help will be greately appreciated.

Generally, in 8i, folks would use sql loader to accomplish this. Sql loader does exactly what you want, but is an external application, so it would probably be easiest to schedule it to run using your operating system's scheduler (i.e. cron on Unix, Task Scheduler on Windows). You could certainly write a PL/SQL procedure that called the external sql loader application, and use the Oracle scheduler to schedule it, but that strikes me as more effort than it's worth.
If you're using 9i, you could look into external tables, which would simplify the process greatly.

I am using GRC Compliance Calibrator and have downloaded the default Global rules defined in Compliance Calibrator using the Rule Architect -> Utilities->Export rules.
This gave me a massive txt file with a lot of tables and data. Reading through this forum, I did figure out that lines starting with M are the header rows for the tables and D rows are the data rows.
My question is, how do i figure out what each of the Virsa tables stand for (e.g. VIRSA_CC_FUNCACT, VIRSA_CC_FUNCPRM) ?
I tried SE11 and looking up these tables in the SAP environment associated with this CC install, however it says that the table was not found.
Could someone please point me to :
A) A list of the common Virsa CC tables and their descriptions ?
OR
B) How can i find what these tables stand for online or in the SAP environment?
Many thanks !

Hi Santosh,
There is no option available to export only the customized rule sets to another system. The export rules option will give all the rules that are available in that system.
You can do in the below manner
a) Extract the data from Export rules
b) Open that text file in a spreadsheet and edit the spreadsheet [Remove the rule sets & the rules not required in production system]
c) Save the spreadsheet in UTF-8 text file
d) Upload them in the production.
The above procedure is bit complex and cumbersome -as changing the text file is risky. Even a space will not generate any rules in the RAR. I would suggest rename the new rule set in different naming convention and upload in your test environment before uploading the text files in Production.
But, using the Export and Import option you cannot upload only the customized rule set as the extract happens for the entire rules sets available in the system.
Thanks and Best Regards,

Upload .txt file into Database Table

Hi,
I was wondering if someone could please point me in the right direction. I've been looking around the forum but can't find anything to help me achieve the following.
I would like to be able to upload a .txt file using a webpage. Then store the information inside this file into database tables.
eg. contents of mytextfile.txt:
richard
10 anywhere street, anytown, somewhere
111 222 333 444
joe
9 somestreet, elsewhere
999 888 777 666
peter
214 nearby lane, overhere
555 555 555 555
I would like to insert this data into a table.
eg. table name = CONTACTS
userid = primary key (using sequence)
username = (line 1 - richard, joe, peter)
address = (line 2)
phone_no = (line 3)
As you can see the records will appear 1 at a time and will have a blank line between records. Is there anyway for me to upload a file like this and have it placed into tables?
I have seen http://otn.oracle.com/products/database/htmldb/howtos/howto_file_upload.html but this seems to be for uploading a whole file and downloading the same file, rather than extracting data from the file.
I hope I have managed to explain my problem.
Many thanks,
Richard.

Richard,
HTML DB allows you to upload CSV files via the Data Workshop. That data would then be parsed and inserted into a specific table. Alternatively, if you have your data in an Excel spreadsheet, and it is less than 32k, you can copy & paste the data directly into HTML DB's Data Workshop, which will then parse and import it into the Oracle database.
The one obstacle you may have to overcome is converting your data from the format you outlined to CSV format. Specifically, you would have to make this:
richard
10 anywhere street, anytown, somewhere
111 222 333 444
Look something like this:
"richard","10 anywhere street, anytown, somewhere","111 222 333 444"
Hope this helps,

Hi

What do you mean by that? Are you trying to display that amount of text and you get an error. Are you trying to read from the server and you get there an error?
> also is there any way to store the content in mobile phone.
Using RMS. But be aware of the size limit specific to every phone.
