Basic levels questions

1.) When moving the the dark or light value sliders, why does it also move the midrange slider? Aren't midrange values independent of light or dark values?
2.) I understand that every histogram is different and there is no right histogram. With that said, it does show if an image is too dark or too light and if I am just aiming for a good balance I am dragging the white slider to the left to lighten it up, and I am dragging it to where the histogram is just touching the bottom. Is there also some guideline to follow for the midrange slider where I can look at the histogram and determine which way to drag the slider?
Thanks.

The middle slider, the gamma control, doesn't specify an actual midrange value. It specifies a gamma adjustment according to its position relative to the low and high sliders, not its absolute location along the x axis. Its default position is midway between the low and high sliders, which has a value of 1.0 and will result in no gamma adjustment. When the low or high input control is moved, the gamma slider will move to maintain its position relative to the low and high slider as its value is maintained.
Move the gamma control left to stretch the histogram, opening up the shadows and compressing the highlights to brighten the image without clipping the highlights. Move it right for the opposite stretching and darkening effect.

Basic iPhoto questions:

I have some Basic iPhoto questions before I start using the program:
- does iPhoto apply any compression or change images in any way when they
are imported?
- after images are imported, can the original source folder of images be deleted off of the mac?
- can Quicktime files exported from iPhoto be viewed on a Windows computer?
- can iPhoto handle large resolution images that might be as large as 8-15mb each? does it display them quick? are there any known file size issues?
Thanks!!!!

kat.
Is there a way to use iPhoto on a network so other users can read and possibly write to an iPhoto library on a networked mac?
iPhoto is a consumer level photo organiser, not a server. It's possible to share photos but libraries are very difficult and fraught with the danger of database corruption. Some have reported success.
Is it possible to password protect or secure certain images in the library so they can not be seen by anyone?
No. The best I can suggest there is to create a second library and store it in a secure area like a protected dmg. But remember, you can only have one library open at a time.
After photos are deleted from iPhoto, are there any remaining traces or cached files anywhere other than the trash
If you delete photos from iPhoto and empty the iPhoto trash then the pics are removed from the Finder as well. They remain as findable as any other deleted file from that point, which is, very, if the searcher in knowledgeable.

SRM 7.0 RFx: Supplier not able to reply to Header level questions

Hi Gurus
I am currently working on SRM 7.0. I am facing a strange issue.
While creating an RFX I am able to create questions as both item level and header level and able to assign weights to the same. I am also able to see questions along with weights at the supplier's end however when I try to create bid it shows weights at header level questions as zero and the supplier response to the question is also not accepted.
For questions at item level it is just working fine.
Please suggest what could be wrong. waiting for your replies.
Sohil

Daniele,
it could be due to multiple purchasing org. assignment to the suppliers.

Object class deployment - Basic form question

OK, I subclass calendar object from Oracle provided standard
object class. What do I need to deploy to use this form now
apart from calendar.pll and my fmx. What about the object class
from which I sub-class. Do I need to compile and deploy that
also? How will form resolve this on run time the parent object
class as I really did not copy, just sub class and we do not
deploy original class? Basic form question. Thanks.

You can set the "help" property on the field (which gives you the little "information" icon link beside the field).
You could also try adding another field of another class above or below:
<Display class='InlineAlert'/>
<Display class='ErrorMessage'/>

Very basic waveform questions

Hi - for whatever reason, I have never been able to get my hands around graphs and their data. Currently I have a parallel loop running, which aquires the present reading from a piece of lab equipment . Obviously this output is not an array, but single points. What is the proper way of charting this onto a waveform chart? Should I be shifting the data out of the while loop, and then appending the new data to an array? Currently I use the 'build array' on the output, and send this to the chart.
By surface appearance this looks to work. However my timebase is off. Because the sample time is not always consistent, what is the best way to configure the dT/d0? Should I actively be measuring the time to aquire the signal, and piping this into the chart?
Thanks for entertaining my entry level questions!

v2009 devel. w/RT

Hi - thank you for your response and explaination. I have attached a VI, which works exactly as I need. :-)
My next question is how do I combine the data to stack these two plots (vs overlay). In the past I have clustered the two 'arrays' of data, but I can not cluster the two waveforms. I tried to bundle the two waveforms, as well as build waveform (from output of two waveforms).
Getting there,
Jamie

Basic Level Trigger Detection

Hi..
I am new to LabVIEW so please bear with me.. I am trying to measure the RPM of my motor which has an optical pick up tachometer attached to it.. The signal is analog and has two states
1. 0 (here the output is in the order of millivolts and is very low)
2. 1 (Here the outout is a steady 10V)
i need to find the time between the two leading edges of the high state so that i can convert it to an RPM. but my basic level trigger detection always outputs a FALSE value even if the signal is above the set LEVEL. hence i am not able to get a time stamp differnce at all..
i dont know if there is a better way to do this. its basically just measring the pulses of my signal. Can anyone suggest a way
Attached is the VI
Solved!
Go to Solution.

Hi Shankar,
If you use the timestamp of the trigger location, it should be more accurate.

Basic level trigger reset

Hi,
Can Anyone explain to me about the "Basic Level trigger detection.vi". I tried using that and it works fine but i cant seem to reset the trigger... What does resetting the trigger do? What is hysteresis for?
Thanks,
Sebastian

Hello Sebastian,
Hyteresis is used to avoid problems due to noise during the electrical interpretation of an input signal level. The following link tells you a bit more about the Schmitt Trigger that uses hysteresis. Regarding the hysteresis input of the "Basic Level trigger detection.vi" this is the way it works:
hysteresis specifies the amount above and below level through which signal in must pass before a trigger level crossing is detected. Trigger hysteresis is used to prevent noise from causing a false trigger. For a rising edge slope, the signal must pass below level – hysteresis before a trigger level crossing is detected. For a falling edge slope, the signal must pass above level + hysteresis before a trigger level crossing is detected
The reset signal is used to force the reset of the input signal on the next call of the VI. If such a reset is inactive, the VI stores the last input signal value and will use it as the initial value the next time the VI is called. Please note that this input is defined as FALSE by default
Hope this helps you.
Best regards

Basic level trigger

anyone pls help
i am using labview 7.1
with the vi 'basic level trigger', i need to determine the location of signal with the threshold level. for what i know, the vi can only detect once within one sampled block of data. if within one sampled block of data, it consists of many curves?with the same threshold level value, i need to determine many location(time/index), how m i going to do?
thanks for enlightening me

Very High-Level Question on Approach (PI ccBPM or CE7.1?)

All -
I have a very high-level question. I am not current on what would be the appropriate tool for my scenario.
My scenario...
Transitioning business to use new sales order system.
This will be a phased roll-out, not Big Bang.
Company ordering website needs to send orders to one of two systems (new and old).
Assume order has a flag or some other value that is an indicator to which backend application it should be sent.
Each recieving application has an order insert web service, which would be in PI 7.1's ESR.
What we "envision" is that there would be some kind of fronting web/enterpise service that would read the "flag", then pass the message to the appropriate web service (and on to the appropriate application).
But I really am not clear how to architect this, if any rules "engines" (ccBPM or in CE 7.1) would be or should be used.
You opinions are welcome...
Thank you for your time...

Hi Eric,
It would be more elegant , if you can classify this orders logically and provide two user interfaces one for each type.
But coming back to your question , if you are planning to implement the process in BPM , you could utilize the capabilities of BRM for this purpose . BRM comes with CE 7.1 and works in conjunction with BPM.
[BRM Help|https://www.sdn.sap.com/irj/sdn/nw-rules-management]
Once you want a complete roll out , you can remove the BRM decision making.Logically this would solve the purpose. ccBPM is not really positioned for this approach. It can be used when you need to interact with multiple systems using different protocols.
Caveat : The use of BPM will restrict your UI to WebDynpro Java (atleast for now). The whole process needs to be built around webservices or RFCs.

Adding Date/Time Field + X Number of Days - Basic Calculation Question

I am assuming this is a basic calculation question. New to Adobe LiveCycle Forms.
I have a simple form containing a table. The table appears as such:
Text
Formatted as Date/Time Fields
Header 3
Monday
user wil choose the beginning date (Date/Time) this is DateTimeField1
Tuesday
this should calculate DateTimeField1 + 1
Wednesday
this should calculate DateTimeField1 + 2
Thursday
this should calculate DateTimeField1 + 3
Friday
this should calculate DateTimeField1 + 4
Saturday
this should calculate DateTimeField1 + 5
Sunday
this should calculate DateTimeField1 + 6
Calculations are performed after the date is chosen for Monday. My mind tells me the simple calculation of DateTimeField1 + 1 is not going to work (and in fact doesn't!) as it needs to change Monday to a number first. I saw on another thread the following:
Num2Date(Date2Num(Date(DateTimeField1), "DD.MM.YYYY")+7, "DD.MM.YYYY")
Thought this was going to get me close. No cigars though!
Any quick help is greatly appreciated. And since I am new to this, details about what needs to be changed would be great too!
Thanks

Here an addition for you date field.
This FormCalc script in the exit:Event will check it the selected date is on a monday.
If not it will go the days back until the last monday.
var Selection = Date2Num($.formattedValue, DateFmt(2))
var WeekDay = Num2Date(Selection, "E")
var NewDate
if (WeekDay eq 1) then
          NewDate = Selection - 6
elseif (WeekDay eq 3) then
          NewDate = Selection - 1
elseif (WeekDay eq 4) then
          NewDate = Selection - 2
elseif (WeekDay eq 5) then
          NewDate = Selection - 3
elseif (WeekDay eq 6) then
          NewDate = Selection - 4
elseif (WeekDay eq 7) then
          NewDate = Selection - 5
else
          NewDate = Selection
endif
$ = Num2Date(NewDate, "EEE DD.MM.YYYY")
Hope this helps, too.

Basic Exporting Question

My main question is a very basic exporting question, but here is a super-condensed explanation of my big-picture goal for context:
Large (~450 MB) aiff on CD --> trim w/ Quicktime --> small (~16 MB) MP3 in iTunes
I would like to take an audio file (aiff) that is approximately 450 MB and export it from Quicktime and in doing so, reduce the file size and convert it to MP3. When I simply try to export it, it doesn't ask me about what size I want, nor does it give the option of MP3 formatting.
I have figured out how to reach my goal, but it's a mess. After I make my trims in QT, I have to:
1. select "share" instead of "export".
2. It asks me what size I want and I select small.
3. The file is then exported as a Quicktime movie into Mail and the size is reduced from 450 MB to about 20 MB.
4. I then have to "right-click" on the attachment in the email that is created,
5. save the attachment,
6. discard the email,
7. import the file into iTunes, and
8. create an MP3 in iTunes to finally arrive at my goal.
This seems like a ridiculously convoluted process to change a large aiff to a small MP3 and put it in iTunes. Any suggestions?

Thanks. I guess the basic answer to my question is that it can't be done in one or two fell swoops. The problem is that it starts on a burned disc, and I need to make edits to it before it ends up in iTunes (to be eventually used in iWeb). I was hoping to avoid juggling back and forth between iTunes and QT. I either would have to send it back to QT to do the edits after -->iTunes-->mp3, or import the large file from the CD to QT, make the edits, save changes, import large file to iTunes, convert to mp3.

Need example in basic level of java..

can anyone give me an example of how to count the frequency of numbers occur and how to sort the numbers in ascending order?
output:
Numbers before sort: 1,3,2,1,1,1,3,4
Numbers after sort: 1,2,3,4
Frequency: 4,1,2
p/s: i'm a beginner to java programming.. all i want is a very simple example to guide me.. the example must be in basic level of java that a beginner can understand..
anyway.. thanks a lots..

public static void main(String[] args)
int[] ints =
{ 1, 3, 2, 1, 1, 1, 3, 4 };
Arrays.sort( ints );
TreeMap tm = new TreeMap();
for ( int i = 0; i < ints.length; i++ )
if ( !tm.containsKey( ints[i] ) )
tm.put( ints, 1 );
else
tm.put( ints[i], ((Integer) tm.get(
ints[i] )) + 1 );
Collection c = tm.keySet();
Iterator i = c.iterator();
while ( i.hasNext() )
int num = (Integer) i.next();
System.out.println( num + " - " + tm.get( num ) );
Would be even easier (and prettier) with generics...

ASA 5505 Interface Security Level Question

I am wondering if someone can shed some light on this for me. I have a new ASA 5505 with a somewhat simple config. I want to set up a guest VLAN on it for a guest wireless connection.
I set up the ASA with the VLAN, made a trunk port, set up DHCP (on the ASA) on the guest VLAN, configured NAT, etc. Everything seem to be working with that. Guests are getting address on the correct subnet, etc.
The only issue I have is that the Guest VLAN (192.168.22.0) can get to the secure (VLAN1 - 172.16.0.0). I set up the guest VLAN (VLAN 5) with a security level of 10, the secure with a level of 100. I figured that would be enough. To stop the guest from accessing the secure, I had to throw on an ACL (access-list Guest-VLAN_access_in line 1 extended deny ip any 172.16.0.0 255.255.255.0)
Can someone show me what I did wrong?
Thank you for any help!
To create the VLAN, I did the following:
int vlan5
nameif Guest-VLAN
security-level 10
ip address 192.168.22.1 255.255.255.0
no shutdown
int Ethernet0/1
switchport trunk allowed vlan 1 5
switchport trunk native vlan 1
switchport mode trunk
no shutdown

Hi,
To my understanding they should not be able to connect to the more secure network IF you DONT have an interface ACL configured.
One very important thing to notice and which I think is the most likely reason this happened is the fact that as soon as you attach an interface ACL to an interface then the "security-level" looses its meaning. The "security-level" has meaning as long as the interface is without an ACL. This makes the "security-level" only usable in very simple setups.
What I think happend is that you have "permit ip any any" ACL on the interface that allowed all the traffic.
Your option is to either remove the interface ACL completely or have the ACL configured like you have now. I mean first block traffic to your secure LAN and then allow all other traffic which would allow the traffic to Internet
Hope this helps

Basic swing question

I just started looking at swing yesterday because I want to provide a GUI to replace a command line utility we use. I've basically finished it but have a quick question about form - I will get some literature later but would like to get a feel from the people here. If you have a JFrame with a few JPanels each which contain some other components, what is the best practice for variable declaration? Should I just declare the variables locally or should I make them instance variables? The reason I ask is that I have a button that submits a message but that message is dependant on check boxes, etc. from from the frame. If I declare them at the method level I then have to start passing them around whereas if I declare them as instance variables I can access them very easily BUT this may not be good form.
For example:
my class is SendMessageToo so in the main method I have a line like:
final SendMessageToo smt = new SendMessageToo();
now all the instance variables that I have can be accessed my the methods simply using smt.methodOne(), etc. Does that seem OK or is it just pure crap? :-)

Thanks, that was something that crossed my mind before I just made eveything an instance variable. It was during that process that I thought, do these all need to be instance variables? Then I thought, SHOULD they all be instance variables. At that point my brain imploded so I came here. :)

4 basic java questions..

ok so I already learned Java last year (in grade 11), but my teacher didn't really teach anything, we learnt everything by ourselves from the API... so theres a lot of things I actually don't understand, but for now I want to ask 4 basic questions:
1. What does static mean?
2. Why would u "final" a constant variable? ie. If you have a variable called SIZE which is set to 5, so if u want it to be a constant, just never change its value. But what does the keyword final do to it?
3. What's super? I see it sometimes, and my teacher showed us in the applet exampls to use super.paint(g) or somethign like that for the paint method, but I never use that because I noticed it works fine without it..
4. Whats a question mark? I saw a game that was made in java and it had a lot of places where it had a question mark , which was part of the syntax. For example,
int j1 = i != 0 ? i - 1 : 199;
OR
JUMPVEL = (fSuperSlime) ? 65 : 31;
I really don't understand these lines...
feel free to answer any of these questions...

wow cool...thanks.. that question mark thing is nice
saves a few lines..
now, about super, so u mean u can access the parent
class's variables?Variables, methods, constructors, if the access level is such that it's allowed.
