Making enum with string cases

I have a case structure with multiple string cases. Would it be possible to use the info from the case structure to make an enum? Is there a script out there that can do that? When I am making a state machine, I like to develop my states first and my my enum later. It is hard for me to make an enum with all the cases first. What's your preference?
Kudos and Accepted as Solution are welcome!

Sorry, I didn't mean to use the word difficult. I do use type-def already, but I just find it troublesome to modify the enum multiple of times. I only want to update it one time.
That sounds like you never will modify the software. In my experience that is just wishful thinking. As soon as the application works you or whoever is using your application will come up with new requirements to include.

How do I use a Case Structure with Strings?

I need to use a string list to set up a set of cases to be performed. Is it possible to tell a single case structure to do "a, b, c, and d, but not e or f" or "do a, c, d, and f, but not b or e" etc... when you use a string containing the cases to be used?

Blackavar,
A case structure will only execute a single case at a time. If you want to have multiple cases execute in parallel, then you would need to have multiple copies of the case structure and split the string apart and wire them to all of the needed case structures.
This could be done with reentrant subVIs to run truely in parallel. Anther method would be to have 6 different case structures, all with 7 cases each. The 7 cases would be "a", "b", "c", "d", "e", "f", and "0". Your input sting will need to be built up so that it will always be 6 characters long and then split up so that each character goes to one of the case structures. You would have your needed code for cases a - f. Case "0" would do nothing.

[solved]Anybody ever had a problem with a case making it difficult to charge?

I purchased a gently used ipod 4g from eBay. I was pretty thrilled with it. It was still new enough to have some limited warranty time left. Dec 23. I experimented with different apps for a couple of days. I had to recharged it once. No problem. I purchased a gel case with a screen protector, so it didn't get it scratched, or beat up. I set it up and it was looking pretty nice. It was a clear gel case so it didn't alter the look at all. I installed some more apps and read some ipod tutorials. I installed mo gv app and found I had an iphone 4 with a free cell phone contract. I needed a second charge. I plugged it into my wall outlet adapter.. After 4 hours nothing. I changed the wall outlet. After 4 hours nothing. I thought I was having a cord problem because my ipod would neither charge nor mount as a flash drive on my computer usb port. I googled ipod trouble shooting and was advised to do the things that I had done & 1)reset it, and if that didn't work 2)buy a new cord. If that didn't work, use the apple limited warranty and get them to fix or replace. I did 1) and 2). Nothing. I was very desperate and getting ready to send it back to apple. Then it struck me that the only thing that had changed physically to the ipod since I last charged was putting on the case. I wondered if the case was interfering in some way. I took it off and put on the cord and plugged into the old wall adapter outlet. This worked, now my ipod is charged. I also found that I could charge with the case on if I pulled the front of it up a little before putting on the cord. Problem fixed.
I guess I am writing this hoping it might save someone else the aggravation of sending an ipod to get if fixed only to be told there is nothing friggen wrong with it. Maybe this should be added to the online troubleshooters?.

Debit Items not getting picked while making payment with F110

HI,
When making payment with F110, items with Debit balance is not getting picked.
Example:
Payment method is assigned in the Maser data.
For a particular vendor one item has a credit balance- posting key 31.
We have posted another JV with F-02 and debited that vendor with Posting key 21. (Payment Method is not entered in the line item)
When we run F110 the credit balance is picked and debit balance is being shown in exception list.
When we got to FB02 and insert payment method in debit line item and then again run the F110 then system pickes all line items and pays the net amount.
The question is why system is not considering Payment Method from Master Data in debit line item, while in credit line item it is picking payment method from the master data.
Do I need to do any setting for it so that it should automatically take payment method from master data even in case of Debit line items.
Regards
Sanjay

Hi All,
Thanks for your quick replies.
But it does not solve my problem.
When I am not assigning any payment method to either Debit or credit line items, system picks (payment method from Master data) for only credit line items and ignores debit line items.
But the problem is that when I assign payment method to debit line item (which is similar to what has been assigned to vendor Master Data) system groups both debit and credit line items and makes payment of only net amount.
My question was why system considered the debit line item for making payment if I manually enter payment method in the line item, if system has been designed only for out going payment. In my opinion It should have reacted similarly irrespective of whether payment method entered in the line item or not.
Regards
Sanjay

Little problem with Strings.

          I have an little problem with Strings, i make one comparision like this.
          String nombre="Javier";
          if( nombre.equalsIgnoreCase(output.getStringValue("CN_NOMBRESf",null)) )
          Wich output.getStringValue("CN_NOMBRESf",null) is "Javier" too, because I display
          this before and are equals.
          What I do wrong?.


You are actually making your users key in things like
"\026"? Not very user-friendly, I would say. But
assuming that is the best way for you to get your
input, or if it's just you doing the input, the way to
change that 4-character string into the single
character that Java represents by '\026', you would
use a bit of code like this:char encoded =
(char)Integer.parseInt(substring(inputString, 1),
16);
DrClap has the right idea, except '\026' is octal, not hex. So change the radix from 16 to 8. Unicode is usually represented like '\u002A'. So it looks like you want:String s = "\\077";
System.out.println((char)Integer.parseInt(s.substring(1), 8));Now all you have to do is parse through the String and replace them, which I think shouldn't be too hard for you now :)

Java Switch Statement with Strings

Apparently you cant make a switch statement with strings in java. What is the most efficient way to rewrite this code to make it function similar to a swtich statement with strings?
switch (type){
               case "pounds":
                    type = "weight";
                    break;
               case "ounces":
                    type = "weight";
                    break;
               case "grams":
                    type = "weight";
                    break;
               case "fluid ounces":
                    type = "liquid";
                    break;
               case "liters":
                    type = "liquid";
                    break;
               case "gallons":
                    type = "liquid";
                    break;
               case "cups":
                    type = "liquid";
                    break;
               case "teaspoons":
                    type = "liquid";
                    break;
               case "tablespoons":
                    type = "liquid";
                    break;
          }

I'd create a Map somewhere with entries "liquid", "weight", etc.
public class Converter {
    private static Map<String, List<String>> unitMap = new HashMap<String, List<String>>();
    private static String[] LIQUID_UNITS = { "pints", "gallons", "quarts", "millilitres" };
    private static String[] WEIGHT_UNITS = { "pounds", "ounces", "grams" };
    static {
        List<String> liquidUnits = new ArrayList<String>();
        for (int i = 0; i < LIQUID_UNITS.length; i++) liquidUnits.add(LIQUID_UNITS));
unitMap.put("liquid", liquidUnits);
... // other unit types here
public String findUnitType(String unit) {
for (String unitType : unitMap.keySet()) {
List<String> unitList = unitMap.get(unitType);
if (unitList.contains(unit))
return unitType;
return null;
It might not be more "efficient", but it's certainly quite readable, and supports adding new units quite easily. And it's a lot shorter than the series of if/else-ifs that you would have to do otherwise. You'll probably want to include a distinction between imperial/metric units, but maybe you don't need it.

How is it possible to use Index Seek for LIKE %search-string% case?

Hello,
I have the following SP:
CREATE PROCEDURE dbo.USP_SAMPLE_PROCEDURE(@Beginning nvarchar(15))
AS
SELECT * FROM HumanResources.Employee
WHERE NationalIDNumber LIKE @Beginning + N'%';
GO
If I run the sp first time with param: N'94', then the following plan is generated and added to the cache:
SQL Server "sniffs" the input value (94) when compiling the query. So for this param using Index Seek for AK_Employee_NationalIDNumber index will be the best option. On the other hand, the query plan should be generic enough to be able to handle
any values specified in the @Beginning param.
If I call the sp with @Beginning =N'%94':
EXEC dbo.USP_SAMPLE_PROCEDURE N'%94'
I see the same execution plan as above. The question is how is it possible to reuse this execution plan in this case? To be more precise, how
Index Seek can be used in case LIKE %search-string% case. I expected that
ONLY Index Scan operation can be used here.
Alexey

The key is that the index seek operator includes both seek (greater than and less than) and a predicate (LIKE). With the leading wildcard, the seek is effectively returning all rows just like a scan and the filter returns only rows matching
the LIKE expression.
Do you want to say that in case of leading wildcard, expressions Expr1007 and Expr1008 (see image below) calculated such a way that
Seek Predicates retrieve all rows from the index. And only
Predicate does the real job by taking only rows matching the Like expression? If this is the case, then it explains how
Index Seek can be used to resolve such queries: LIKE N'%94'.
However, it leads me to another question: Since
Index Seek in
this particular case scans
all the rows, what is the difference between
Index Seek and Index Scan?
According to
MSDN:
The Index Seek operator uses the seeking ability of indexes to retrieve rows from a nonclustered index.
The storage engine uses the index to process
only those rows that satisfy the SEEK:() predicate. It optionally may include a WHERE:() predicate, which the storage engine will evaluate against all rows that satisfy the SEEK:() predicate (it does not use the indexes to do this).
The Index Scan operator retrieves
all rows from the nonclustered index specified in the Argument column. If an optional WHERE:() predicate appears in the Argument column, only those rows that satisfy the predicate are returned.
It seems like Index Scan is a special case of Index Seek,
which means that when we see Index Seek in the execution plan, it does NOT mean that storage engine does NOT scan all rows. Right?

Help with string object code

Hello,
First off thanks in advance to anyone who helps. I am trying to write a program that using a class string object to convert this kind of "text speech" to english. For example if the user inputs "HowAreYou?", I want the program to output "How are you?" I am having too much trouble with strings for some reason. This is what I have so far and I am not sure where to go from here. Should I use a do loop to check through the input string until it is done seperating the words? And how should I go about doing that?
import java.util.Scanner;
public class P8
public static void main( String args[] )
char choice;
String line = null;
String answer = null;
Scanner scan = new Scanner(System.in);
do
System.out.println();
System.out.print("ENTER TextSpeak sentence(s): ");
line = scan.nextLine();
System.out.print( "Converted to English: \t ");
System.out.print( textSpeaktoEng( line ) );
System.out.println();
System.out.print("Want more TextSpeak?\t\t ");
answer = scan.next();
choice = answer.charAt(0);
if( scan.hasNextLine() )
answer = scan.nextLine();
}while(choice != 'N' && choice != 'n');
public static String textSpeakToEng(String s)
String engStr = null;
if( Character.isUpperCase( s.charAt(j) ) )
engStr += ? ?;
engStr += Character.toLowerCase( s.charAt(j) );
scan.close();
}

I got my program to compile and run but I have a problem. If I input something like "ThisForumIsGreat" it will output just "t f i g" in lower case letters. Any suggestions?
import java.util.Scanner;
public class P8
public static void main( String args[] )
   char     choice;                          // Repeat until n or N
   String line   = null;                     // Sentences to toTextSpeak
   String answer = null;                     // Repeat program scan
   Scanner scan = new Scanner(System.in);    // Read from keyboard
   do
      System.out.println();
      System.out.print("ENTER TextSpeak sentence(s): ");
      line = scan.nextLine();                // Read input line
      System.out.print( "Converted to English: \t    ");
      System.out.print( textSpeakToEng( line ) );
      System.out.println();
      System.out.print("Want more TextSpeak?\t\t ");
      answer = scan.next();                  // Read line, assign to string
      choice = answer.charAt(0);             // Assign 1st character
      if( scan.hasNextLine() )               // <ENTER> character
        answer = scan.nextLine();            // Read line, discard
}while(choice != 'N' && choice != 'n');    // Repeat until input start n or N
public static String textSpeakToEng(String s)
   String engStr = null;
   int i;
   for ( i = 0; i < s.length(); ++i )
   if( Character.isUpperCase( s.charAt(i) ) )
     engStr += " ";                                  // Append 1 blank space
     engStr += Character.toLowerCase( s.charAt(i) ); // Append lowercase
   return( engStr );

Need help with upper case

I'm stuck on my coding when I have to write a function to
detect upper cases has been used in a sentence
For example if my array element has this:
2345
SAINT PAUL
STREET
APT 5
PHILADELPHIA
I need to be able to write a code to let me know that the 2nd
OR 3rd OR 5th element is written in upper case letter
Or if I set the variable not as array, 2345 SAINT PAUL STREET
APT 5 PHILADELPHIA
I need to be able to detect that at least one of the section
on that street name is written with upper case
Can anyone help please?

compare() cf function performs a case-sensitive comparison of
2 strings
and returns 0 is the strings are the same. so you can compare
an
uppercase version of the string to the original string, and
if the
comparison returns 0 then your string is in uppercase:
<cfif compare(ucase(myarray[2]), myarray[2]) is 0>

<cfelse>

</cfif>
the above code compares the value of the second array element
converted
to uppercase to the original value of the second array
element. if the
result is 0, i.e. the uppercase and original strings are the
same, then
you know the original string is in uppercase.
if you are dealing with a single string (which is equivalent
to a
space-delimited list), then use appropriate list function to
get
required list element, i.e. listfirst(), listlast(),
listgetat()...
<cfif compare(ucase(listlast(mylist, " ")),
listlast(mylist, " ")) is 0>

<cfelse>

</cfif>

Enums with constant-specific method implementation

Just faced the following problem. I have a persistent class with one of the fields of it is enum with constant-specific method implementation:
@Persistent
public class Message
   static public enum Type
       DEFAULT
           @Override
           public String getDescription() { return "Some description"; }
       public abstract String getDescription();
   private Type type;
}When I try to store the record, I get the exception:
java.lang.IllegalArgumentException: Class could not be loaded or is not persistent: messages.Message$Type$1The problem seem to be in that compiler creates a separate class, namely Message$Type$1.class for the DEFAULT instance and this class is not known by BDB..
If I remove the constant-specific method from enum, everything's working fine (as the ..$1.class is not created by compiler).. Except the fact that I'd like to have constant-specific methods there..
Any ideas on this? Maybe it's a bad idea to create constant-specific methods if it means that each constant would get own class file (and they would bloat the storage routines)?

Hi Mikhail,
I recreated the problem here and you're right, constant-specific methods aren't working. This isn't something we thought about, to be honest, or tested.
Just based on an initial quick look I see that for the compiler generated class, the Class.isEnum method returns false, which is why we don't recognize this as an enum and eventually why we throw the exception you're seeing. But assuming that we can identify the class as an enum (that shouldn't be too difficult) I don't know what other problems we will run into in trying to support this.
For now I think the best thing is to avoid using the constant-specific methods. I have opened a ticket (#18357) so that we'll remember to look into this in more detail and see whether it can be supported in the future.
If we are able to support it, then I'm hoping that we won't to store extra metadata for constants that have methods. In other words, I'm hoping that we won't have to add any extra storage or processing overhead.

Ring with string value

I would like to know if there is a way to make a single control (either a ring or otherwise) where a string that is displayed to the user has a string as its output value.
For instance, I have a power laser with a serial communication port and the command to turn on the laser diodes is LASER1;
I want to display the string "DIODES ON" to the user, but have the control provide the value "LASER1;" when selected.
This is easy to do with two controls, for example, I can have an enum with the user display strings and a matching enum with the laser command strings, but then I have to ensure that any change affects both controls.
If it is a single control, it is less likely to have an error when a change is made.
Any help is greatly appreciated.
I am using LabView 2009
Solved!
Go to Solution.

Perhaps I should have been more clear.
There are approximately 20 commands to be sent to the laser from which the user can select.
Each string to the user has a corresponding command.
Since this is programmatic for automatic operation; as well as single commands for manual operation, I would like to have a single control with 20 strings and corresponding commands.
For example:
User                 Laser
Diodes On         Laser1;
Diodes Off         Laser;
Mode Current    Opmode0;
Mode Power      Opmode1;
Gate Open        Gate1;
Gate Closed      Gate0;
A single button or a caption string is not adequate.

Skype not for Making friends with Strangers?

As opposed to before the Microsoft ownership, now you can only do like 20 or anywhere from (20-30) skype friend requests to strangers( that you find in friendship sites boards) before your account gets suspended.
Which doesn't make sense at all.
prior to the microsoft ownership, i had 100s of skype international friends because i could try and try and sure some would block me but still they didn't report me as SPAM and end my account. Now all you want is to try to make friends and they can simply report you as spam with no reason and your a ccount will be suspended.
I've had like 5 accounts suspended recently including 1 today. and i just made this account like yesterday and did like 20 skype friend requests.
So is skype only for making friends with people you know in real life who you know will accept your request?
So it's no longer to make friends with strangers in Skype friend sites..where people look for friends and give out their IDs? In case you don't know there's many of these sites ou there because people want to make friends internationally etc.

I took over as the I.T. Manager (now Director) a couple of years ago. I had a great working relationship with our CFO and saw many high-priority projects funded without much difficulty.
Alas, our beloved CFO has moved on and we have a new one starting in the next few days. I have had a chance to meet her, and she seems really great. She even mentioned she is driven towards new tech.
The IT Director / Manager relationship with the governing bodies is crucial to the success of an organization. Do any of you in IT Management have tips on building good working relationships with the new executives?

Array access notation with strings?

I may be confused, but I thought you could use array access
notation with strings. Can someone tell me why this code doesn't
work (or suggest new code):
the code is meant to rewrite the block of text in tText at a
rate of one character per frame... (when the function is called
once per frame) but it doesn't work.

DZ-015,
> I may be confused, but I thought you could use
> array access notation with strings.
It's made for objects, actually. The array access operator,
[], allows
you to access elements from an Array instance and also lets
you access
properties from any sort of object. The "trick" it provides,
in this latter
case, is that you can refer to these properties -- within the
brackets --
with strings, so it's often used to reference objects
dynamically.
> var sWorkingText:String = tText.text;
Here you've declared a String variable and set it to the
TextField.text
property of some textfield. So far, so good.
> var sNewText:String = oPhotoText[sPageFocus];
Here, you've declared a String variable, but it seems that
you're
setting it to a property of the oPhotoText object. That's now
how this
works.
The array access operator allows you to *use* strings to get
at an
object's properties:
// functionally equivalent
someObject.property1
someObject["property" + 1];
var x:Number = 1;
someObject["property" + x];
Does that help?

Mixing Ram with different CAS latencies in K7n2 Delta-L?

I have been using 512mb Kingston Value Ram in my computer, pc3200, with CAS latency of 3.0. I just purchased some Corsair value select 512mb ram pc3200 with CAS latency of 2.5. I know you are not supposed to mix ram with different speeds (like 400 vs. 333) but does it matter if the CAS latencies are different?
I'm running an AMD XP 1800+, K7n2 delta-L, nforce2 motherboard from MSI. Someone at a computer shop told me they tried mixing Kingston 3.0 CAS with Corsair 2.5 CAS, and said his computer wouldn't even post. So I'm wondering if this is an isolated problem, or you will always run into this problem if you mix ram with different CAS latencies.
If anyone has experience with this issue, please share with the board. Thanks!
Chris

The age old question, will the components I bought be compatible ? There are those that have bought identical matching memory that didn't work. In my case, I had an ECS K7S5A that used PC2100 Crucial memory, the sticks neither matched (at one time they did, but one stick died and they sent me the closest thing they had.). Neither of these Crucial sticks was identified by a configurator as being compatible with the K7N2 Delta L that I decided to buy. In the end, not only did both sticks work, but I put them in as single channel mode (ram slots 1 & 2), but later changed the configuration to dual channel mode (ram slots 1 & 3, even 2 & 3). It worked flawlessly in all three configurations. Sorry for the long answer, but in essence, there are no guarantees and your worries will drive you crazy. When memory is mixed, you reduce the likelihood of compatibility, even when you go beyond the recommended products that were specifically identified.
That guy at the computer shop, did he ever indicate or isolate the true reason why the memory wouldn't work ? Maybe, maybe not. I would think with a disparity in memory, the bios is the key to setting the settings for the worst stick of the bunch. Then again, the products you get might overclock to what the better sticks run at. My assumption is that mixed sticks, the bios retards settings to this in "auto" mode. When you force it manually, it may work or it may fail. One thing you oughta know, each and every stick has the manufacturers id encoded onto them at the very least, just like the firmware on other items indicates a manufacturer code and other data that allows these things to be compatible. So know you face that battle going in with any of them. If the bios programming doesn't allow it to work, from that perspective, there'll be problems.
