• vector expression evaluation

  Hello world
  
  Can someone tell me the following expression evaluation.
  
  int i = 0;
  System.out.println (i ++ + ++ I + ++ i);
  
  
  Please help me...

  Ok.. Thanks for this knowledge...

  If the operands are evaluated, left right then exit this expression must be of 6 but is 5? How?

  No, it must be exactly what it is. If such was not the case, it would mean that there is a HUGE mistake in a very basic part of Java a beginner like you could find, but who somehow don't get it fixed, despite Java used in thousands of existing applications.

  int i=0;
  System.out.println( i++ + ++i + ++i); 
  

  When we reached the first term (i ++), the value of i is 0. The value of this expression is the value of i, before the increment, if we determine that the value of this expression is 0. Then, we increment I 1. Running so our total is 0 and the value of i is 1.

  When we reached the second term (++ i), we increment all first I between 1 to 2. Then, we determine the value of this expression, which is the new value of i is 2. We have therefore 0 + 2 = 2 for our running total, and the value of i is now 2.

  When we reached the third mandate (++ i once again), we increment all first I have 2-3. Then, we determine the value of this expression, which is the new value of i is 3. So we have 0 + 2 + 3 = 5 for our total and the value of i is 3.

  It's as if we have:

  int i = 0;
  int j = i++; // j  = 0; i = 1;
  int k = ++i; // i = 2; k = 2;
  int m = ++i; // i = 3; m = 3;
  System.out.println(j + k + m); // 0 + 2 + 3

• simple expression evaluator

  Hi all
  
  need help with an expression evaluation:
  user enters a string like "x * x + dx * dy" or 'x * dx - dy * y' and I Flash on hidden that in an actionscriptline in the code, it looks like:
  
  x = 3;
  DX = 0.6;
  DY = 0.1;
  AA = x * x + dx * dy;
  trace (AA);
  
  and the result would be: 9.06
  
  Now my problem is to convert the operator.
  Anyone for a solution for this newbie?

• Do in Expression evaluation

  Do everything in
  ((

  Val (locals. ((DailySelfCalTimeMsgBoxInputHours)<0&& val(locals.dailyselfcaltimemsgboxinputhours)="">23)). ((Val (Locals.DailySelfCalTimeMsgBoxInputMinutes)<0&& val(locals.dailyselfcaltimemsgboxinputminutes)="">59)). RunState.Sequence.Main ["Message Popup"]. Result.ButtonHit! = "2"

  MSG Box to read at the time of user input
  }

  I have this logic, but do so while the loop was never released.  If I press the button cancel the do while loop is exited.  However, Locals.DailySelfCalTimeMsgBoxInputHours Locals.DailySelfCalTimeMsgBoxInputMinutes meet the requirements above in the Do While expression, the loop never ends.  In the framework of the Expression of Post of Message box, I converted the above string variables of numeric type and display values as expected.  So, I'm not sure why when I try to use Val (String) in the Do While expression, the evaluation does not work as expected.  Can someone shed light on this problem?

  Pseudocode:

  While

  hours < 0="" and="" hours=""> 23

  Or

  minutes < 0="" and="" minutes=""> 59

  Or

  buttonhit <> 2

  end while

  Ok. Hours is never negative and more than 23. Minutes will be never greater than 59 both negative. buttonhit could not be 2. Thus, it seems that you will never get a real on buttonhit.

  I think that either you have you a larger and less reverse, or you need to replace your ANDS by RHA.

  Good luck

• Is VirtualCenter 2.5 SQL 2005 Express Database limitted to 5 guests

  I heard that when VirtualCenter 2.5 use SQL SERVER 2005 Express, it is limited to only 5 guests and 50 virtual machines.

  Is this fair?

  Wee using SQL SERVER 2005 Express and have 4 hosts (esx servers) and nearly 50 virtual machines.

  Now we need to install 2 guests most, witch would require us to install a new SQL Server, if it is limited to 5 hostsL

  Hello

  Yes, you heard right. The database delivered with VC, i.e. Microsoft SQL Server 2005 Express database allows you to configure a limited number of hosts and virtual (5 guests and 50 virtual machines).

  Please go through page 14 of this doc: http://www.vmware.com/pdf/vi3_35/esx_3/r35u2/vi3_35_25_u2_installation_guide.pdf

  I suggest you to upgrade SQL Server 2005 Express to SQL Server 2005.

  Thank you.

• Boolean expression evaluation

  Hello

  Flex, 4.0.x

  I came across a strange behavior, by evaluating the following expressions (function):

  public function calculateIsNext():void
  {
       if ( _currentState == "FirstPage" )
       {
            isNext = ((StoreManufacturerCode!='') && hasSelectedProducts);
            dispatchEvent( new Event( "ChangeValidation" ) );
       }
  }
  
  

  the problem lies on the line where the proximity is calculated, whenever I stop here during debugging, the two part of the expression are real and just leave this function after this line, dispatchEvent is not managed.

  I got this line also with if else statements, where proximity = true, never evaluated even the two parts of the expression are ture

  Anyone encountered similar behavior?

  r. sandor

  Sometimes, you will see this, if you are using the old code.  Try to delete the contents of bin-debug and then goes to the project > Clean and the cleaning of your project.  You can also see this in functions that may be related, if the underlying code generated decides that the value has not changed.

• bind variables and expression evaluation

  Hi friends,

  I was looking at a query that uses a bad plan. DB is 11.2.0.3 with active user bind peeking. It is a simplified version showing the problem:

  Select egp.bsn

  , egp.klantnummer as 'Persoonsnummer '.

  , egp.samengesteldenaam as 'Samengesteldenaam '.

  , egp.geboortedatum as 'Geboortedatum.

  of pr_eigenschappen2 egp

  where

  (egp.bsn =: b1 or: b2 is null)

  and rownum < 51

  EGP. BSN is varchar2 (10) and has a high selectivity (almost unique) and is indexed btree. table and index have adequate statistics.

  When it is run with b1: = 928818 and b2: = 928818 (linked both as varchar2 (10)) a full table scan + filter is used on pr_eigenschappen2.

  If the query is changed to

  Select egp.bsn

  , egp.klantnummer as 'Persoonsnummer '.

  , egp.samengesteldenaam as 'Samengesteldenaam '.

  , egp.geboortedatum as 'Geboortedatum.

  of pr_eigenschappen2 egp

  where

  (= egp.bsn: b1 or 928818 a null value)

  and rownum < 51

  
  

  the index on the bsn is used, and the query does not 3.9 seconds but 1 millisecond.
  

  
  

  If I had a choice, the query would be different. I don't want to talk about the reason for the request, I would like to know why the optimizer does not use the index in the first case.
  

  
  

  
  

  Jan-marten,

  as Hoek wrote: "the optimizer must take into account the fact that the bind peut var be null, and then a full crawl is required...". ». For the bsn = part: b1 a systematic index scan range would be a good idea, but for: b1 is null, there is only one relevant case producing a result: NULL IS NULL and this condition the CBO only a full table scan or a full scan of the index taking into account (after all a complete analysis of the index may also be called 'index range scan across the table' - but that would be contrary to the 'Beach' in its name).

  By the way: I think that the trick of gather_plan_statistics is not very useful in the test case since you do not use display_cursor with allstats format. He might even have a negative impact on performance since statistical rowsource are quite expensive - depending on the timing of your OS routine. I think that Mr. Lewis has written something on this effect, in his notebook.

• Export multiple property of a digital test limits as an expression

  I am able to import and export the limits of the digital with expressions and several digital tests with expressions.

  What about using the charger of property for expressions within limits for multiple digital tests?

• Description Expression step

  Hello

  I add a few features to a custom step type. One of the features is showing the data some of the step in the description field.

  But some data in an array of dynamic size.

  Is there a way to browse the tables in the field of expression?

  This issue is not limited to the Expression of Description step. You can use it in each Expression.

  Hello

  -Did you change your computer, after which the question began?

  There are two causes:

  Anti-malware tools:

  The most common cause of repeated items dating back to your real e-mail program is probably anti-malware tools that try to sweep the outgoing email, or interfere with the correct functioning of the mail program. It is a common cause of repeated downloads (or failures) of e-mail, and when the feature is activated to parse messages, it can interfere here as well.

  According to the type of intervention, the e-mail program responds by saying: "well, that didn't work, I'll try to send again"- and again and again.

  Step 1:

  The solution here is pretty simple: locate this function in your suite antivirus or security and turn it off. You will need to close and restart your e-mail program or even restart your machine for the change to take effect.

  Note: Activate the anti-malware after the test.

  Outlook Express mailbox limits:

  Outlook Express apparently has a size limit of 2 GB file for the mailboxes.

  Normally, this does not affect the majority of people, but I've certainly seen reports to do exactly what you described, as the sent items folder approach 2 gigabytes. Small mails could do for a while, but a greater commitment could be enough to exceed this size limit and therefore cause the problem.

  Step 2:

  My recommendation is to create a new folder - call it what you like; Maybe, something like "SentArchive" and move all messages in your sent items in the Archive folder file sent. Who should;

  (a) keep all your messages if you need to refer to them.
  (b) empty the sent items folder so that this problem does not happen.

  Step 3:

  a. your Outlook Express, learned to tools > accounts > mail tab.
  b. double-click the account name > Advanced tab.
  c. only uncheck the box marked "Break apart messages.

• The Apple AirPort Express Base Station is a good solution?

  I'm moving so leaving the wifi station that Verizon gave me. I think I have the Apple AirPort Express Base Station by station WiFi. I connected an iMac (main computer) MacBook Pro, iPad, iPhone.

  My main question is how this used for the WiFi base station compares to others on the market.

  Thank you!

  Johnny

  The AirPort Express has limited the ability of speed due to its slow and limited capacity wireless Ethernet port due to its very small built in WiFi antennas.

  However, if the plan of your new Internet Service Provider (ISP) is limited to about 50 Mbit/s, then the Express would probably be OK if most wireless devices will be located near the AirPort Express Terminal.

  If the budget allows, an AirPort Extreme is a much better product... up to 10 times the speed of the Express... with additional WiFi antennas located just above the 'tour' to improve performance.

  If your new ISP plan is 100 Mbps or higher, then AirPort Extreme would be a better match.

  If you are considering other routers from other manufacturers... we cannot comment at all on their performance without knowing the number of brand and model of the device you are considering.

• Airport Extreme router's Express is connected by wire, East of 1 Gbps ports on switch it extreme on 100Bt now?

  Hi all

  In my house, the extreme is connected to a fiber modem 250 / 250 MB/s and I plugged a time Machine as an Express via CAT6 UTP. All serve as a router and provide 2.4 and 5 GHz wifi on the different floors of the House. Just a question: Express has 2 ports ethernet 100BT, Extreme and Time Machine have 3 1000BT Ethernet ports. The extreme switch mode back all 100BT because of the Express ports?  Because that would explain the downgrade in the port on the extreme speed after that the PS3 has been used connected to the Express.

  

  The extreme switch mode back all 100BT because of the Express ports?

  No.... but any device connected to the Terminal AirPort Express will have a maximum speed of 100 Mbps. So, if you connect a 1 000 compatible device to the Ethernet port on the Express, it would appear as a device of 100 Mbps on the network as the Express is limiting speeds.

  So, if you want a device that is capable of 1 000 Mbit/s to have 1 000 Mbit/s speed on your network, it will have to connect to AirPort Extreme or time Capsule.

• evaluate the expression error

  Hello

  TestStand 4.1, I'm trying to copy a container of FileGlobals to StationGlobals, based on a name.

  The following works, even if the browser of Expression says that it will cause a runtime error because "error in the call for expression int 'Evaluate'. Unexpected token:... »

  Locals.Name = "Name1"

  StationGlobals.TargetContainer = evaluate ("FileGlobals" + Locals.Name + ".") SourceContainer")

  where StationGlobals.TargetContainer and FileGlobals.Name1.SourceContainer are of the same named type.

  I tried to use EvaluateEx(), but found no construction to make it work. What would be the syntactically correct way to do this?

  Thank you

  Peter

  Peter,

  the reason for the 'mistake' the evaluation of the expression at development time, it's that he is a "stacked" expression

  First, you set Locals.Name a new value. I think in your sequence Locals.Name is by default an empty string. Then use this value in another part of the expression.

  Since there is no SequenceContext (no performance), the value of Locals.Name is not actually modified by the first part of the expression leaving the Evaluate() to search for a "FileGlobals" property... SourceContainer. Since two '.' one after another are illegal for search strings, the entire expression evaluation fails.

  This error does not occur during execution, because the first part of the expression does not actually change Locals.Name (for the SequenceContext) to be "Name1", while the second part will result in Evaluate ("FileGlobals.Name1.SourceContainer").

  hope this helps,

  Norbert

• Change step description

  In the main sequence I copied/pasted a case statement. Has been able to change the name of the step of the sequence in the new case, but can't find out how to change its description.

  Thank you

  JVH

  Dennis Knutson says:
  The description is the value to compare with the statement. What do you want it to be? To change it, you will need to rename to something else, the step to copy and modify the Expression of Description step

  Thanks for posting. I copied and renamed but hard to find how to change the Expression of Description step. I can see, but it is grayed out, cannot be changed.
