Multiple Expressions

I'm trying to wrap my brain around some XPATH. I have two variables in a switch statement that I want to compare and take one of three paths..
Path1: Both Are presnet
Path 2/3: Either is present, but not the other.
Here's my XPATH - my question is how do I evaluate BOTH of these statements in one expression?
bpws:getVariableData('InvokePersonTokenOutVariable','payload','/ns6:getPersonTokenProcessResponse/ns6:personToken')!=''
and
bpws:getVariableData('InvokeCaseTokenOutputVariable','payload','/ns2:GetCaseTokenProcessResponse/ns2:CaseToken') !=''
I tried using the AND operator and () in different ways, but it still breaks. Any ideas?
thanks

Hi Brian,
If I understand correctly, you are trying to evaluate NULL strings in your XPATH. If my assumtion is correct, then I must share that in my experience, evaluating NULL strings by - bpws:getVariableData('InvokePersonTokenOutVariable','payload','/ns6:getPersonTokenProcessResponse/ns6:personToken')!='' does not work properly.
An alternative can be using the "string-length()" function and base your XPATH on the string length and not on the content when it comes to NULL String handling.
If my assumption is not correct, then please ignore this post:)

Multiple speakers without multiple expresses

Is there a way to have a mac-mini control many speakers with iTunes without the hardware burden and radiation burden of many airport expresses?
I wired up my house with lots of speakers all over the place, and the wires all go to one location. Ideally, I could buy a 12-channel amp, and have a mac mini run all 6 locations, with various iphone and ipod-touches able to control music selection and which zones are on or off.
Is that possible without buying 6 airport expresses? (and they would all be on the same power-brick... kind of a waste of plastic and radiation)
Thanks!

Not if you want each zone/speaker set to run separately - different music to each zone - no. A Mac mini has only a single stereo out, as does an Airport express, so neither could supply different audio programs to different amplifiers. I don't believe that you could do that even with multiple Airport Express units; I don't think iTunes can stream different streams to different Airports, though I could easily be wrong. If you want multiple zones with each one controllable separately, you'll probably need a much more sophisticated software/hardware setup like the Sonos systems, none of which are probably going to be cheap.

Call executable argument with multiple expressions

I'm using the "call executable" step type in TS 4.2. My normal command line works with windows [sflashldr com1 w 0 config.cfg binary.bin] where the bin file flashes my chip according to the cfg. I think that this is a multiple argument expression... TestStand returns "cannot open file".
How should the argument expression be configured?

Hi mcnearymw,
Is that the whole error message? If not it would be useful for us to see the entire error message.
Also have you seen this White Paper? It might give you a better idea of how the Call Executable step works in TestStand. http://www.ni.com/tutorial/8847/en/

Multiple Expressions -- how to?

I have both keyframes and a wiggle expression on the position property of a layer.
Can I stack expressions like wiggle(n1,n2) and loop_out("cycle",0) on the same property?

A little background for you, Navarro: You'll notice that wiggle() and loopOut() don't take any properties as parameters (loopOut(position, ... ), for example). That is because they are both member functions of the property class, meaning each must be called as a child object of a particular property (e.g. transform.position.loopOut()). When you call loopOut() without appending it to a layer's property, you are actually implicitly appending it to the property "this", which is the object-oriented-programming-speak for "the object I'm currently operating inside" (in your case, the position property to which you are applying the expression).
Hopefully this will help you understand why you can't use code such as "loopOut().wiggle()" or "wiggle().loopOut()". The reason is that loopOut() and wiggle() don't return properties, they return values in whatever form their parent property dictates (single numerical values for most properties, arrays for multi-dimensional values like position, etc.). Neither function is a member of the return value of the other function. This is why using the two in conjunction requires that each be applied to a different property.
That said, it wouldn't be terribly hard to do the looping yourself. Here's an expression that loops the transform and its wiggle:
>newTime = time;
>if(numKeys > 0 && time > key(numKeys).time){
> loopDuration = key(numKeys).time - key(1).time;
> newTime = time % loopDuration;
>}
>wiggle(10, 50, octaves = 1, amp_mult = .5, t = newTime)
Wiggling the loop (i.e. each loop having its own distinct randomness) would be tougher, I think, and combining the results of expressions on multiple properties would probably be the way to go for that.

XL Reporter multiple expressions in selection

Trying to do something simple. I created two paramter expressions for the GlAccount. One CostCenter and Second expression Divison. When I select the selection tab on my report and use either a row expansion or summary - I enter the natural account with the selection with an And for costcenter and an And for divison from the parameter expression field. When I accept the result xlreporter is returning only first paramater expression I entered. I am on 2007 SP01 A with Patch 10. What am I missing?

Gordon,
I have two parmaters setup as an expression. One based on GlAccount Segment_2 named @DIV the second based on GLaccounts Segment_1 named @ISL. On my row I select GLAccounts Sement_0 begins with 5 And @DIV And @ISL when I press ok it only diplays @DIV in the selection box. If I mannuly try to enter the selection it give me an error.

Airport Extreme and Multiple Expresses with iTunes

I have an airport extreme base station running a bgn network and six airport expresses connected (three wired and three wireless) to stereo systems throughout the house. They seem to stumble all over themselves with an IP address distribution or something that makes them cut in and out after playing for about 20 minutes. I've tried assigning IP addresses but it doesn't seem to work. I'm guessing that one of the wireless expresses loses signal for a second and that causes all the issues. Any thoughts?

So the airport extreme is setup and the wireless is going. But when I hook up the airport express, I've plugged it in and when I use airport utility through the desktop which is hardwired connected to the airport extreme, the express does not show up the devices list.
Can somebody explain to me how the airport express is used to boost the signal of the airport extreme using airport utility within windows vista? thanks!

Multiple expressions on the grep command

I am trying to grep for an IP and result code (TCP_DENIED), but I'm not having any luck. My command line is as follws:
grep -e x.x.x.x*TCP_DENIED -i -t accesslogs
I've tried different variations such as leaving a space between the IP and TCP_DENIED and adding an * between the variables, but nu lick.
Can someone please provide the correct command for this?
Thx,
Jeff

Grep is "menuy"....
Just type "grep", hit enter, follow the prompts... I have seen reference to escaping out the periods in an IP address in the regex... (eg 192\.168\.0\.10)
Enter the number of the log you wish to grep.
[]> 1
Enter the regular expression to grep.
[]> 172.168.151.1
Do you want this search to be case insensitive? [Y]>
Do you want to search for non-matching lines? [N]>
Do you want to tail the logs? [N]> y
Do you want to paginate the output? [N]> y
Hope that helps.

How do I return a true value for multiple expressions?

Hi, I hope this question makes sense...
In, for example, cell A1, I would like to return a True value when:
C1>B1, and
C2>B2, and
C3>B3, and
C4>B4, and
C5>B5
That is, if all column C values are greater than all corresponding column B values, then I would like to return a True value in cell A1.
If one or more C values are less than or equal to their corresponding B values, e.g. B4<=C4, then I would like to return a False value in cell A1.
Can this be achieved using a single formula in cell A1? If so what would that formula be?
Thanks

In column D I will insert the formula:
=IF(OR(ISBLANK(B),ISBLANK(C)),"",IF(C>B,"",1))
In A1 I will insert:
=SUM(D)<0
or
in column D
=IF(OR(ISBLANK(B),ISBLANK(C)),"",C>B)
in A1
=COUNTIF(D,FALSE)=0

Adobe After Effects: Keep "Expression-Relations" when duplicating multiple layers

Hi there!
Just wanted to ask, whether there is a way to keep the relations of expressions going when duplicating layers. E.g. I have two layers, "LayerA" and "LayerB". Now I have an expression going on in "LayerB" saying, that its position always equals the position of "LayerA". Now when I duplicate those two and get "LayerA 2" and "LayerB 2" I want the expression in "LayerB 2" to reference to "LayerA 2"'s position rather than "LayerA"'s position!
While it is no problem to simply change the expression when there is only one of them, it gets quite hard when you have multiple expressions going on ...
Thx in advance

Unix Log Monitoring regular expression not picking up alerts

Hi,
We are moving our unix monitoring to SCOM 2012 SP1 rollup 4.
What I have got working is indvidual alert logging of Unix Log alerts by exporting the MP and changing the <IndividualAlerts> value to true and removing the suppression xml section then reimporting the MP.
What I am trying to do is use the regular expression to peform the suppression of specific event (such as event codes).
The expression is:
((?i:warning)(?!(.*1222)|(.*1001)))
ie Search the log for "warning" (not case sensitive) then check if events 1222 or 1001 exist if so return no match, if they dont exist then return true.
I use the built in test function in SCOM when creating the rule and the tests come back as expected but when I inject test lines into the unix log, no alerts get generted.
I suspect it could be the syntax not being accepted on the system (its running RedHat 6 )
I have tested this with regex tools and works.
When I try and test it on the server i get:
[root@bld02 ~]# grep ((?i:Warning)(?!(.*1222)|(.*1001))) /var/log/messages
-bash: !: event not found
[root@bld02 ~]# tail /var/log/messages
Nov 13 15:07:26 bld02 root: SCOM Test Warning Event ID 1001 Round 18
Nov 13 15:07:29 bld02 root: SCOM Test Warning Event ID 1000 Round 18
Nov 13 15:07:35 bld02 root: SCOM Test Warning Event ID 1002 Round 18
So I am expecting 2 alerts to be generated.
SCOM tests to show expression working:
Test 1 Matching
Test 2 to exclude
Need some help with this, Thankyou in advance :)

Hello,
Here's an example of modifying the MP to exclude particular events. Firstly, I created a log file rule using the MP template that is fairly inclusive - matching the string Warning (with either a lower or upper case W).
I then exported the MP, and modified the rule. I set the IndividualAlerts = true and removed the AlertSuppression element, so that every matched line will fire a unique alert. You don't have to remove the AlertSuppression, but you should use
Individual alerts so that the exclusion logic doesn't exclude concurrent events that you actually want to match.
Implementing the exclusion logic involves the addition of a System.ExpressionFilter definition in the rule. This will use a conditional evaluation of the //row element of the data item. Here's an example of a dataitem matching an individual row:
<DataItem type="System.Event.Data"time="2013-11-15T10:33:14.8839662-08:00"sourceHealthServiceId="667FF365-70DD-6607-5B66-F9F95253B29F">
<EventOriginId>{86AB962D-2F44-29FD-A909-B99FF6FEB2C5}</EventOriginId>
<PublisherId>{EC7EA4B1-0EA5-7E8E-701F-82FEF3367BC4}</PublisherId>
<PublisherName>WSManEventProvider</PublisherName>
<EventSourceName>WSManEventProvider</EventSourceName>
<Channel>WSManEventProvider</Channel>
<LoggingComputer/>
<EventNumber>0</EventNumber>
<EventCategory>3</EventCategory>
<EventLevel>0</EventLevel>
<UserName/>
<RawDescription>Detected Entry: warning 1002</RawDescription>
<CollectDescription Type="Boolean">true</CollectDescription>
<EventData>
<DataItem type="SCXLogProviderDataSourceData"time="2013-11-15T10:33:14.8839662-08:00"sourceHealthServiceId="667FF365-70DD-6607-5B66-F9F95253B29F">
<SCXLogProviderDataSourceData>
<row>warning 1002</row>
</SCXLogProviderDataSourceData>
</DataItem>
</EventData>
<EventDisplayNumber>0</EventDisplayNumber>
<EventDescription>Detected Entry: warning 1002</EventDescription>
</DataItem>
Here is the rule in the MP XML. The <ConditionDetection>...</ConditionDetection> content was what I added to do the exclusion filtering:
<Rule ID="LogFileTemplate_66b86eaded094c309ffd2631b8367a32.Alert" Enabled="false" Target="Unix!Microsoft.Unix.Computer" ConfirmDelivery="false" Remotable="true" Priority="Normal" DiscardLevel="100">

<LogFile>/tmp/test</LogFile>
<UserName>$RunAs[Name="Unix!Microsoft.Unix.ActionAccount"]/UserName$</UserName>
<Password>$RunAs[Name="Unix!Microsoft.Unix.ActionAccount"]/Password$</Password>
<RegExpFilter>warning</RegExpFilter>
<IndividualAlerts>true</IndividualAlerts>
</DataSource>
</DataSources>
<ConditionDetection TypeID="System!System.ExpressionFilter" ID="Filter">
<Expression>
<RegExExpression>
<ValueExpression>
<XPathQuery Type="String">//row</XPathQuery>
</ValueExpression>
<Operator>DoesNotContainSubstring</Operator>
<Pattern>1001</Pattern>
</RegExExpression>
</Expression>
</ConditionDetection>
<WriteActions>
<WriteAction ID="GenerateAlert" TypeID="Health!System.Health.GenerateAlert">
<Priority>1</Priority>
<Severity>2</Severity>
<AlertName>Log File Alert: ExclusionExample</AlertName>
<AlertDescription>$Data/EventDescription$</AlertDescription>
</WriteAction>
</WriteActions>
</Rule>
I traced this with the Workflow Analyzer as I tested, which shows the logic being applied. Here is the exclusion happening:
Here's more info on the definition of an ExpressionFilter:
http://msdn.microsoft.com/en-us/library/ee692979.aspx
And more information on Regular Expressions in MPs:
http://support.microsoft.com/kb/2702651/en-us
You can also have multiple Expressions in the ExpressionFilter joined by OR or AND operators.
Also, if you are comfortable with the MP authoring, you can just skip the step of creating the rules in the MP template and just author your own MP with the VSAE tool:

Using multiple PC's as remote speakers?

I have a few PC's on my network at home. I also have a couple of airport expresses. I run I-tunes on each PC, sharing music throughout the house. From each PC I can stream music to multiple rooms using the airport express(es) as remote speakers.
What I want to do is also stream to other PC's as if they were remote speakers. I want other PC's in my network to show up as remote speakers so I can stream synchronous music to any room with a PC AND any room with an airport express.
Can this be done??

Hello.
Any feature requests can be submitted to the following links below
http://www.apple.com/feedback/itunesapp.html
http://www.apple.com/feedback/airportexpress.html
*With Airtunes you are able to stream music to multiple speakers meaning
1. Multiple Airport Expresses connected to Multiple speakers
2. Multiple Expresses connected to Speakers & also hearing the audio from the computer it is broadcasting from.
Now the bigger question I believe you are asking is can other computers pickup on this broadcast of sound?
Never tried it myself. I am not aware of iTunes being able to pickup the broadcast from the speaker selection in the bottom right hand corner. I am aware of it being able to broadcast it's sound to other speakers on the network though.
Hopefully other users can post their thoughts and how they got this to work. At this current time I know you can connect multiple expresses, and have it broadcast throughout the house based on where each express it is and the speakers they are connected to.

Can't connect to Airport Express speakers in iTunes

Hi,
I have a Time Capsule and an AX (802.11n).
The AX is connected to a stereo and speakers, and is configured to Join my existing wi
iTunes sees the remote speakers, but when I select them I get an error message and cannot connect.
Also, Airport Utility (6.0) is not allowing me to change the speaker settings (name, password). These options are greyed out, despite the Enable AirPlay option being checked.
Thanks!

OK, I just solved this same (or similar) problem for myself...
My iTunes on MacMini has been connecting to multiple Expresses for years. Every once in a while, iTunes will "forget" that it is to play through the Expresses and reverts to Computer only. So I would just pop open the Airplay menu and select Multlple Speaker and turn them all on again. Weird, but solvable.
Tonight, no go. I could not select any of the Airport Expresses in this Airplay "speaker chooser." I am running OSX 10.6.8 and iTunes 10.6.1. Was it the recent 10.6.1 update? Not sure, but it points to that.
(By the way, are you saying Airport Utility software update, or do you really mean the Express firmware update?)
Anyway, I tried various normal things, restarting this and that. No luck. Googled this and that, etc. Finally took the plunge and updated the firmware in the Expresses and Time Capsule, which restarts the units. This DID NOT solve the problem (not right away, at least).
I notice that my MacBook Pro's iTunes could connect to all my Expresses (even befoe the Express' firmware updates). This was my first troubleshooting check. This got me to think that this was an Airport vs Ethernet issue. (My Mini and all Expresses are hardwired with Ethernet).
So I turned off Ethernet on the Mini and connected it to my LAN with Airport. Sure enough, now the Mini's iTunes could select all the Expresses!
Weirder still, I turned off the Mini's Airport and reconnected it to my LAN using Ethernet. Voila! The speaker settings in iTunes stuck and now everything is fine. (For now!)
Computers... errrrr......

Connecting to multiple speakers in itunes

I have two airport express units. Athough I can select either, or, in itunes how do I stream too both simultaneously as the 'bezel' will only let me select one station. Any ideas gratefully received. Thanks

One possible reason is firmware for the expresses. Multiple speakers option dictates the expresses have firmware V6.3. You also have to be running iTunes V6.02 or 6.03 to stream to multiple expresses.

How to format dates in SQLExec query

I am trying to archive Lookout data to an Oracle database using SQLExec. I started with existing SQLExec code that put data into Access. Following is that code:
"Insert into wind_temp (Rdate,Wind,Temp) values ("&text(now(Timer3),"0.00000000")&",
"&text(\\SCADA1\Server\Drivers\Corral\ROCSouth.Wind,"0.000")&",
"&text(\\SCADA1\Server\Drivers\Corral\ROCSouth.Temp,"0.000")&")", 8, no);
The Rdate column in wind_temp table is date type. If I change the type to varchar2 (string) this works, so my ODBC connection is good. The problem is that for date fields Oracle needs a string in DD-MON-YYYY (i.e. 01-JAN-2002) format or string data converted to a date (i.e. to_date('01-JAN-2002 12:00:00','DD-MON-YYYY HH24:MIS')). Is there a way
using the now() or other function to build a "to_date" string like above to pass to Oracle?

Here you go:
text(now(),"dd/mm/yyyy hh:mm:ss")
This will give you slashes and not dashes and a number for the month and not the abbreviated name.
Here is the expansion that does what you need:
left(text(now(),"dd/mm/yyyy hh:mm:ss"),2)&"-"&if(mid(text(now(),"dd/mm/yyyy hh:mm:ss"),4,2)="01","JAN",if(mid(text(now(),"dd/mm/yyyy hh:mm:ss"),4,2)="02","FEB",if(mid(text(now(),"dd/mm/yyyy hh:mm:ss"),4,2)="03","MAR",if(mid(text(now(),"dd/mm/yyyy hh:mm:ss"),4,2)="04","APR",if(mid(text(now(),"dd/mm/yyyy hh:mm:ss"),4,2)="05","MAY",if(mid(text(now(),"dd/mm/yyyy hh:mm:ss"),4,2)="06","JUN",if(mid(text(now(),"dd/mm/yyyy hh:mm:ss"),4,2)="07","JUL",if(mid(text(now(),"dd/mm/yyyy hh:mm:ss"),4,2)="08","AUG",if(mid(text(now(),"dd/mm/yyyy hh:mm:ss"),4,2)="09","SEP",if(m
id(text(now(),"dd/mm/yyyy hh:mm:ss"),4,2)="10","OCT",if(mid(text(now(),"dd/mm/yyyy hh:mm:ss"),4,2)="11","NOV",if(mid(text(now(),"dd/mm/yyyy hh:mm:ss"),4,2)="12","DEC","ERROR"))))))))))))&"-"&mid(text(now(),"dd/mm/yyyy hh:mm:ss"),7,15)
The date I got from this was:
11-APR-2002 11:54:35
I would recommend using multiple expression objects to simplify reading the code. I included it here, all in one expression, so you could copy and paste it for testing.
I tested it on Lookout 5.0. It works.
Study the text() function and the general text manipulation functions. You can do just about anything with a little creativity.

Custom tag - setProperties() not called

Hi all,
I've created my first custom tag with it's own component class, Tag Class, Renderer and TLD. However, when the JSP first loads, the encode() method fails in trying to get the attribute values from the attribute Map - the Map is empty. Upon further debugging I can see that the Tag class is called and the setter methods are called for each attribute but the setProperties() method is never called before release(), so the attributes are never stored in the UIComponent's attribute Map.
Anybody know what I'm doing wrong?
Some code:
Tag Class...
public class ListShuttleTag extends UIComponentTag
public void setProperites(UIComponent component)
super.setProperties(component);
ComponentTagHelper.setString(component, "sourceValue", sourceValue);
ComponentTagHelper.setString(component, "targetValue", targetValue);
ComponentTagHelper.setInteger(component, "size", size);
ComponentTagHelper.setInteger(component, "targetListWidth", targetListWidth);

Gotcha........
First, this is what the jsp spec has to say in sec 1.14.1
When using scriptlet expressions, the expression must
appear by itself (multiple expressions, and mixing of expressions and string
constants are not permitted). Multiple operations must be performed within the
expression.Simple, isnt it ? All you have to is evaluate the expression as a whole.
