Best way to write a fall-through switch statement?

I am trying to write the equivalent of a C-style
switch statement. The attached VI has 2 ways of
accomplishing this. Is there a better way? What are
the pros/cons of the two ways shown in the VI?

I have no better way of doing this, but I'll give you my opinion as to the
readability and the maintainability.
Readability:
I find option 2 more readable, the entire code is laid out and easy to
see without cycling through cases. It is pretty easy to see what it does
and how it works. Option 1 requires a little more thinking to follow the
logic, but is not undecipherable.
Maintainability:
I would think that option 1 is much more maintainable. Simply add
another case to the case structure and you're ready to go. No rewiring, no
need to clear out more room on the diagram. Seems easy to me. Option 2 is
going to require a little more work, and if room is already scarce on the
diagram, adding another case structure may make wiring more
difficult.
Overall:
I'm not sure I see where I would incorporate this in my code right now,
but if the need arose, I would probably do something like Option 1.

  • What is the best way to call SSH commands through Java technologies

    What is the best way to call SSH commands through Java technologies

    I don't think you can specify the password at the prompt using ssh. Plink has the -pw command option for passwords. What I did was except ssh to ask me and write the password programmatically through the outputStream I obtained from my Process object. I looked for "password: ", and then wrote the password with a trailing newline.
    Both plink and ssh will also ask if you trust the host if it is the first time you are connecting to it. So before just writing the password, check if the program wants verification from you: normally supplying "y" or "n". This should only have to happen the first time the client connects. It looks like thisPLINK:
    The server's host key is not cached in the registry. You
    have no guarantee that the server is the computer you
    think it is.
    The server's key fingerprint is:
    1024 f8:43:61:4c:a2:5b:77:be:5b:a7:bb:1f:f7:79:b3:b7
    If you trust this host, enter "y" to add the key to
    PuTTY's cache and carry on connecting.
    If you want to carry on connecting just once, without
    adding the key to the cache, enter "n".
    If you do not trust this host, press Return to abandon the
    connection.
    Store key in cache? (y/n)
    SSH:
    The authenticity of host '127.0.0.1 (127.0.0.1)' can't be established.
    RSA key fingerprint is e1:02:13:c8:52:c2:23:41:9b:5b:58:2c:18:e6:59:af.
    Are you sure you want to continue connecting (yes/no)?What I did was read character by character from the inputStream until I found things of interest ... like "password: ". You only need to search for this in your method which will launch the ssh or plink Process. Once you have verifyed yourself, you can just pass commands to the Process, which is an ssh connection.
    My suggestion is to read() each byte from the Process's inputStream and write it to stdout. Look and see what you need to be looking for so you can interactive with the program correctly. You can't use readLine here becuase when the ssh asks for the password it does not print a newline. I do know for sure, that ssh will simply print, "passowrd: ". Plink will print this as well if the -pw option is not supplied.

  • Best way to write SELECT statement

    Hi,
    I am selecting fields from one table, and need to use two fields on that table to look up additional fields in two other tables.
    I do not want to use a VIEW to do this. 
    I need to keep all records in the original selection, yet I've been told that it's not good practice to use LEFT OUTER joins.  What I really need to do is multiple LEFT OUTER joins.
    What is the best way to write this?  Please reply with actual code.
    I could use 3 internal tables, where the second 2 use "FOR ALL ENTRIES" to obtain the additional data.  But then how do I append the 2 internal tables back to the first?  I've been told it's bad practice to use nested loops as well.
    Thanks.

    Hi,
    in your case having 2 internal table to update the one internal tables.
    do the following steps:
    *get the records from tables
    sort: itab1 by key field,  "Sorting by key is very important
          itab2 by key field.  "Same key which is used for where condition is used here
    loop at itab1 into wa_tab1.
      read itab2 into wa_tab2     " This sets the sy-tabix
           with key key field = wa_tab1-key field
           binary search.
      if sy-subrc = 0.              "Does not enter the inner loop
        v_kna1_index = sy-tabix.
        loop at itab2 into wa_tab2 from v_kna1_index. "Avoiding Where clause
          if wa_tab2-keyfield <> wa_tab1-key field.  "This checks whether to exit out of loop
            exit.
          endif.
    ****** Your Actual logic within inner loop ******
       endloop. "itab2 Loop
      endif.
    endloop.  " itab1 Loop

    Hi,
    The best way to write PL/SQL (or any code) is in very small increments.
    Start with a very simple procedure that does something (anything), just enough to test that it's working.
    Add lots of ouput statments so you can see what the procedure is doing. Remember to remove them after testing is finished.
    For example:
    CREATE OR REPLACE procedure missing_authorized_services IS
            v_truncate_sql  VARCHAR2 (200);
    BEGIN
         v_truncate_sql := 'truncate table missing_authorized_services';
         dbms_output.put_line (  v_truncate_sql
                        || ' = v_truncate_sql inside missing_authorized_services'
    END      missing_authorized_services;If you get any errors (for example, ORA-00955, becuase you're trying to give the same name to a procedure that you're already using for a table), then fix the error and try again.
    When it worls perfectly, then add another baby step. For example, you might add the one line
    EXECUTE IMMEDIATE v_truncate_sql;and test again.
    Don't use dynamic SQL (EXECUTE IMMEDIATE) unless you have to.
    Is there any reason to use dynamic SQL for the INSERT?

  • Best way to give tablename in create table statement

    hi all,
    what's the best way to give table name while "create statement" in case of performance.. 
    for eg:
    create table tablename(id int,name varchar(20))
    a.) tablename
    b.) [tablename]
    c.) (tablename)
    d.) "tablename"
    pls its urgent..
    thanks in advance..
    lucky

    >b.) [tablename]
    As Naomi pointed it out, the above is dangerous because unintentionally special characters or space can be included and accepted by SQL Server.
    Once you introduce special characters in the table name, you have to use [....] forever.

  • What is the best way to write 10 channels of data each sampled at 4kHz to file?

    Hi everyone,
    I have developed a vi with about 8 AI channels and 2 AO channels... The vi uses a number of parallel while loops to acquire, process, and display continous data.. All data are read at 400 points per loop interation and all synchronously sampled at 4kHz...
    My questions is: Which is the best way of writing the data to file? The "Write Measurement To File.vi" or low-level "open/create file" and "close file" functions? From my understanding there are limitations with both approaches, which I have outlines below..
    The "Write Measurement To File.vi" is simple to use and closes the file after each interation so if the program crashes not all data would necessary be lost; however, the fact it closes and opens the file after each iteration consumes the processor and takes time... This may cause lags or data to be lost, which I absolutely do not want..
    The low-level "open/create file" and "close file" functions involves a bit more coding, but does not require the file to be closed/opened after each iteration; so processor consumption is reduced and associated lag due to continuous open/close operations will not occur.. However, if the program crashes while data is being acquired ALL data in the buffer yet to be written will be lost... This is risky to me...
    Does anyone have any comments or suggestions about which way I should go?... At the end of the day, I want to be able to start/stop the write to file process within a running while loop... To do this can the opn/create file and close file functions even be used (as they will need to be inside a while loop)?
    I think I am ok with the coding... Just the some help to clarify which direction I should go and the pros and cons for each...
    Regards,
    Jack

    One thing you have not mentioned is how you are consuming the data after you save it.  Your solution should be compatible with whatever software you are using at both ends.
    Your data rate (40kS/s) is relatively slow.  You can achieve it using just about any format from ASCII, to raw binary and TDMS, provided you keep your file open and close operations out of the write loop.  I would recommend a producer/consumer architecture to decouple the data collection from the data writing.  This may not be necessary at the low rates you are using, but it is good practice and would enable you to scale to hardware limited speeds.
    TDMS was designed for logging and is a safe format (<fullDisclosure> I am a National Instruments employee </fullDisclosure> ).  If you are worried about power failures, you should flush it after every write operation, since TDMS can buffer data and write it in larger chunks to give better performance and smaller file sizes.  This will make it slower, but should not be an issue at your write speeds.  Make sure you read up on the use of TDMS and how and when it buffers data so you can make sure your implementation does what you would like it to do.

  • Best way to write readable code?

    So I'm waist deep in building my GUI by hand and it occurs to me that I'm probably not doing this the best way possible. What I have now is listed below and I was thinking that other possibilities would be to write other methods like initMainFrame() and initSearchPanel() and such that would be called from initComponents() (though I would have to either put the objects outside of those methods, probably declared immediately above the method declaration for readability, or somehow make them class scope that're declared within a method which I think I've seen somewhere, but have been unable to reproduce) or to make new class files that handle this.
    So any comments on my ideas (good/bad/etc) or insight on how you structure your code when making a GUI would be much appreciated.
        public static void initComponents() {
            // main frame
            JFrame mainFrame = new JFrame("CookBook");

  • Best way to write stream to OutputStream?

    Hi, I need to write a string into an OutputStream (socket). I am a little confused how is the best way (most elegant, efficient) to do it.
    Should I use a OutputStreamWriter? Sometimes, I also need to write raw bytes directly.
    Currently, I am using:
    ByteArrayOutputStream output = new ByteArrayOutputStream();
    PrintStream printStream = new PrintStream(output);
    socket.write(output.toByteArray(), 0 , output.size());
    I would appreciate some oppinions.
    Thanks

    Hi, I need to write a string into an OutputStream

    (most elegant, efficient) to do it.
    Should I use a OutputStreamWriter?Yes.
    Sometimes, I also need to write raw bytes directly.But does it happen in the same method? If so, you might need to re-design.
    Currently, I am using:
    ByteArrayOutputStream output = new
    ByteArrayOutputStream();
    PrintStream printStream = new PrintStream(output);
    socket.write(output.toByteArray(), 0 ,
    output.size());What's the BAOS good for? Why not String.getBytes(), if you have to use the bytes?

  • Best way to write specific information to a file

    Hi there,
    I'm looking to write specific information from my program to 2 separate files.
    Before the program runs, it asks the operator for their info (name, password, run ID #, a couple safety checkboxes).
    So, I would like the first file to record log-in information (i.e. The operator's name, the date and time they accessed the program, and the Run ID #) all in a spreadsheet.
    I would like the second file to record data from the different components of the program ( 2 tank levels, a flow meter, and run ID #) in another spreadsheet.
    Any thoughts on the best way to do this? I've looked at using arrays to organize the info/data, and then write to spreadsheet, but I haven't quite figured it out...
    Thanks,
    Daryn

    For the first, you could convert everything to strings, then send an array of strings. For the second, just send an array of numbers.

  • Best way to write entire DVD-R?

    It's come to my attention that certain set top DVD players (Phillips in particular) won't play recordable media with a small amount of information written to the disc. But if you burn more than 4GB to the disc, the player reads the disc just fine. I'm working with a 15-minute program, so I'm obviously not near the 4GB. I'm interested in maximizing functionality and playability on all machines, so I'm wondering if there's a way within DVDSP, Disk Utility or Toast to write the entire disc. I've tested this by inserting video tracks that the user cannot reach from the menus, but the user could easily use the 'chapter forward' function and get lost in the dummy tracks. Thanks in advance for any thoughts.

    Yes, TY media are good, but Memorex? This forum is littered with references to the coasters that they make.
    The media in question here are TY, Verbatim and some leftover Apple brand discs from the old days. DVD-R manufacturer definitely has nothing to do with this. It's definitely an idiosyncrasy of the Phillips player in question. I've never had it happen with any of the other dozen or so players we have around here.
    We maintain many different brands of DVD player in our studios to be able to simulate any situation our products may find themselves in. Our goal is to be able to reach the largest audience possible for our clients, no matter their technological limitations. That is not always easy or even possible, given the amount of old, poor, and poorly maintained computers and DVD players out there. But we try to reach as many as possible. As tempting as it might be to always blame the user's equipment, we have to try to find novel ways of making every project as accessible as possible.
    I'll mark this question as answered, because I've discovered that there is no way to write to the edge of a DVD-R without the requisite amount of QT tracks within the DVDSP project. If anyone ever has any other ideas, please offer them. Thanks to all for contributing.
