Newbie Question: Control DO on Exit

Hello,
I am brand new to LabVIEW and need to get a small project done quickly. I have only really used Express VI's...
I do, however, have a DAQ and control system up and running (I'm sure it could be done much more efficiently, and I plan to refine as I learn)...
What I really need to know are two things:
1) How to ensure a pair of digital outputs are off on start-up (I have them default to off on power-up in DAQmx) but I mean on start-up of my VI.
2) How to ensure they're off on exit of the VI (no matter what the state of the toggle in the on screen, if they stop it, I need the outputs to go off).
Please can anyone give me some help, or an example?
-Jeff

Might I recommend taking some tutorials:
LabVIEW Basics
LabVIEW 101

Newbie question- Controlling computer over internet

I have ARD 2.2, running on ibook G3 using OSX 10.39.
My mom, who lives quite far away just bought a mac (her first) and I'm trying to use ARD to take control of her computer so as to set it up for her.
She's using a new Intel Imac running OS 10.4x Should I be able to control her despite our differences in OS?
The added problem is that her computer is connected through a router, so her IP address starts with a 192, which is usually a locally assigned IP I think.
Anyway, should I be able to take control of her with this setup? If not, would I be able to if she connected directly to the internet (no router)?
Thanks

Don't worry about doing anything to your AirPort Station; nothing there needs to be configured. It's the other router (probably a Linksys or DLink?) that requires configuring as well as yur mom's Mac. You'll need to know the current IP, mask, and router information from the Network System Prefs (TCP/IP). You'll also need to know the DNS server addresses (although sometimes you can just use the router # and be okay).
Setup the Mac (her Mac) with a static IP out of the DHCP range; if her current address is 192.168.1.100, then use 192.168.1.151 as most of the router default to handing out no more than 50 DHCP addresses. Whatever mask has been assigned by DHCP is what you'll want to use for the static setting. The router will be the same thing (whatever it is through DHCP). DNS can be found by logging into the router and checking its "status" page. Alternatively you can call the ISP.
Log into the router, go to the "Port Forwarding" or "Gaming" page, set it forward traffic (both TCP and UDP) on port 3823 and port 5900 to 192.168.1.152 (which is the new address you're using for your mom's Mac). Save the config settings.
Check the router's status page for the DNS and public IP address (the one assigned by the ISP that the router is using "on the outside"). Note this as you'll need it later.
Now you (on your Mac, use the ARD admin app to capture the public IP (mentioned in the previous paragraph). Use the password you (or your mom) set when configuring ARD sharing in the Sharing systems prefs. You're done.

RV042G Newbie Questions

I have the new Cisco RV042G router, and I have just a few "newbie questions" about it as I get started using it:
The firmware on board is v4.2.1.02. Since this is a brand new router, is that the latest firmware?
Under Time>DST Dates, what do I need to configure in there? I'm in the US, Central Time.
I want to use Back to My Mac from iCloud (formerly MobileMe). Under the iCloud preferances pane on my Mac, it's saying: "Back to My Mac may be slow because NAT Port Mapping (NAT-PMP) or Universal Plug and Play (UPnP) is turned off on your router. Turn on NAT-PMP or UPnP." What should I enable on my router in order for Back to My Mac to better function?
I'm using a VOIP phone on the network (only 1 device with a couple phones). Are there any QoS settings I should tweak for better performance of my VOIP phone? I did change the port the VOIP phone is connected to to High (instead of Normal) under Port Settings. Will this help boost performance?
I also want to setup a VLAN on a port for guests to access the Internet, but not have any access to my personal network. Here's the steps I've done so far. Is this sufficient or is there anything else I need to do?
I went to Setup>Network, enabled Multiple Subnets.
I added 192.168.254.1/255.255.255.0 as a subnet.
I went to Port Management>Port Setup, set the port I wanted to use (Port 4) to VLAN2.
I went to Firewall>Access Rules, added two rules:
Deny All Traffic from 192.168.254.0 to 192.168.1.0.
Deny All Traffic from 192.168.1.0 to 192.168.1.0.
Thanks everyone for your help!

Easy. just goto the DHCP field and fill in the Static DHCP fields.
Assigning static IP addresses by adding devices from a list
Click Show unknown MAC addresses. The IP & MAC binding list appears. If the web browser displays a message about the pop-up window, allow the blocked content.
The devices are listed by the IP address and the MAC address. (Typically the MAC address appears on a label on the bottom panel or back panel of a device.) If needed, you can clickRefresh to update the data.To select a device, first enter a descriptive Name. Then check the Enable box. Alternatively, select all devices in the list by clicking the check box at the top of the Enable column.
Click OK to add the devices to the Static IP list, or click Close to close the pop-up window without adding the selected devices. After you click OK, a message appears. The message includes important information. Read it before clicking OK. Keep the browser open and wait until the selected MAC addresses appear in the Static IP list.
Modify or remove list entries, as needed:
To modify the settings: Click a device in the list. The information appears in the text fields. Make the changes, and then click Update. If you do not need to make changes, you can click Add New to de-select the entry and clear the text fields.
To delete an entry from the list: Click the entry that you want to delete, and then clickDelete. To select a block of entries, click the first entry, hold down the Shift key, and then click the final entry in the block. To select individual entries, press the Ctrl key while clicking each entry. To de-select an entry, press the Ctrl key while clicking the entry.
Assigning static IP addresses by entering devices manuallyIn the Static IP Address section, add or edit entries as needed. Remember that the settings are not saved until you click the Save button.
To add a new device to the list: Enter the following information, and then click Add to list.
Static IP Address: Enter the static IP address. You can enter 0.0.0.0 if you want the router to assign a static IP address to the device.
MAC Address: Enter the MAC address of the device. (Typically the MAC address appears on a label on the bottom panel or the back panel of a device.) Enter the address without punctuation.
Name: Enter a descriptive name for the device.
Enable: Check this box to assign the static IP address to this device.
To add another new entry: Enter the information, and then click Add to list.
To modify the settings: Click a device in the list. The information appears in the text fields. Make the changes, and then click Update. If you do not need to make changes, you can clickAdd New to de-select the entry and clear the text fields.
To delete an entry from the list: Click the entry that you want to delete, and then click Delete. To select a block of entries, click the first entry, hold down the Shift key, and then click the final entry in the block. To select individual entries, press the Ctrl key while clicking each entry. To de-select an entry, press the Ctrl key while clicking the entry.
Using the Static IP List to Block Devices
You can use the Static IP list to control access to your network. You can block access by devices that are not on the list or do not have the correct IP address.
Add devices to the Static IP list as described in Static IP Addresses.
Enable or disable the following features:
Block MAC address on the list with wrong IP address: Check this box to prevent a computer from accessing your network if its IP address has been changed. For example, if you previously assigned a static IP address of 192.168.1.100 and someone configures the device to use 192.168.149, the device will not be allowed to connect to your network. This feature discourages users from changing their device IP addresses without your permission. Uncheck the box to allow access regardless of the current IP address assignment.
Block MAC address not on the list: Check this box to block access from devices that are not included in the Static IP list. This feature prevents unknown devices from accessing your network. Uncheck the box to allow access by any connected device that is configured with an IP address in the correct range.
Hope that helps.

[SOLVED] cool'n'quiet & modprobe newbie question

This is probably very newbie question, but I have no idea what to do.
I want to have cool'n'quiet working on my amd64. I turned it on in bios, and downloaded powernowd.
When I type:
> modprobe powernow-k8
> powernowd
it works. I added powernowd to demons in my /etc/rc.conf but after restarting computer it doesn't work - I have to type both commands above again.
How to make my system not forget loaded module after restart?
Last edited by senjin (2007-08-24 19:49:31)

Use either /etc/modprobe.conf or the MODULES= array in /etc/rc.conf. I would have thought powersaved provided a config file from where you could pick a module to load though... sure there isn't one in /etc/ ?
Personally i would opt for powersaved, since i think it's more full featured (it's more a _power_ than a _cpu_ manager), but then again you may not care for anything other than controlling the cpu stepping/speed.

Total Newbie Question ... Sorry :-(

I know it's a windows thing, and I am now converted to Mac but I gotta know this because it's doing my head in. It's a complete stupid green gilled newbie question.
When installing new programs on a Mac can you create shortcuts to the programs on the Dock? I did what I THOUGHT it would be, i.e I made an Alias and stuck it in the dock, but on rebooting my Mac later on, in place of the shortcuts where 3 question marks which when clicked on did absolutely nothing???
Help?

You aren't installing something from a dmg file are you? The dmg is a disk image – kind of a virtual CD. So when you double click the dmg and then get the little disk/hardrive/custom icon on your desktop that is the same as if you had mounted a CD. You then need to drag the application off of that "CD" into your application folder. Then it is truly installed.
You can then "eject" the icon your your desktop. This is what happens when you shutdown and without remounting the image your dock shortcut can't find the original.
Just a thought.

Newbie Question. just installed IE7.. how do I set up a local host to preview sites?

Just define your site in DW as always. For a static site, that's all you need to do.

Newbie Question about FM 8 and Acrobat Pro 9

Hello:
I have some dcouments that I've written in FM v8.0p277. I print them to PDF so that I can have a copy to include on a CD and I also print some hard copies.
My newbie question is whether there is a way to create a PDF for hard copy where I mainitain the colors in photos and figures but that the text that is hyperlinked doesn't appear as blue. I want to keep the links live within the soft copy. Is there something I can change within Frame or with Acrobat?
TIA,
Kimberly

Kimberly,
How comes the text is blue in the first place? I guess the cross-reference formats use some character format which makes them blue? There are many options:
Temporarily change the color definition for the color used in the cross-reference format to black.
Temporarily change the character format to not use that color.
Temporarily change the cross-reference definition to not used that character format.
Whichever method you choose, I would create a separate document with the changed format setting and import those format into your book, create the PDF and then import the same format from the official template.

Domain name settings - Newbie question

Sorry for a newbie question!
I am already pointing a domain name to web hosting for email account. Now, I need an application server to run ERP software and Oracle, and installing Solaris and Oracle need a domain name.
If I point my domain name to the server, how do I receive emails from web hosting???
Install an email server to the application server instead? What can I do if I want the same domain name? Any option?

Setting up a mailserver and making sure it doesn't suddenly turn into a spambox is not something you do with the use of a few commands. I suggest to dive into the Solaris admin guide on docs.sun.com and read up on e-mail and network services.
If that is asking too much of your time you'll be better off getting your ISP to handle all this for you.

Domain Name settings in Solaris - Newbie question

Your questions are completely off-topic for the forum.
These SunOS forums are for questions on "how do I install my OS"
You particular question is in the "how can I install Solaris while using the CD drive" forum.
So, if you had a question on how to edit the /etc/inet/hosts file to establish a FQDN on the computer, then it might be appropriate for the forum.
Unfortunately, I don't have a clue on where to redirect you, except perhaps to the Sun Java Enterprise System suite of applications?

Newbie Question: How much computer do I need?

Newbie Question:
I would like to use MainStage 3 in a live performance environment to play bars, parties, etc. I'm not looping, using it to playback recordings, processing outboard equipment or vocal processing. I want to stop carrying Rolands, Nords, Korgs, etc and get to a controller and a rack with a Mac Mini in it.
I tested a download of Mainstage 3 on my home Mac Mini (late 2012, 3.5 Ghz i5, 4GB RAM, 500GB drive) and it seemed to run fairly well. $30 well invested so I trekked forward... I purchased a Mac Mini (late 2009, 2.52GHz Core 2 Duo, 6GB RAM, 128GB SSD) for $200. I started to do more elaborate keyboard setups to see how the CPU would hold up. It typically runs from 30% to 50% of capacity (CPU and Memory) It actually boots and runs better than the i5. I hear the occasion gitch, but it actually seems to be getting better in time (or I'm rock and roll deaf.
I got a rack, an Airport Express, a Radial USB interface and a Nektar Panorama P6. It's starting to get expensive, but I'm emboldened by the actual quality for the sound and the flexibility of arranging for live performance. What used to take me two and three keyboards to play, I can now fit on one performance patch.
OK, now the question... am I at the limits of this little Core 2 Duo? Should I upgrade the i5 with more RAM and a bigger SSD and use that? Should I get a new(er) i7 and bite the $1,500 bullet for the additional RAM and SSD?
I see that most of you are running pretty nice Macbook Pros with i7 and lots of everything. My needs are modest; am I OK?
BTW, I want to run a Mac Mini in a box because I don't want to carry a laptop out in the open. If I was doing bigger shows I wouldn't care but I play some rowdy bars and constantly have folks hanging off me while I'm playing. It's fun, but hard on gear. If you can't drop it or dip it in beer, it won't last long where I work.
Matt Donnelly

Rule of thumb: newer and faster is better. But, depending the complexity of your needs you may be OK with an older Mac. Some glitches that happen in a live performance are due to loss of communication with USB or Firewire inputs, so make sure they're secure. I recently upgraded from a 2010 Mac Mini 2.6 dual core with 16 GB RAM, which was used live for nearly four years, to the latest Mac Mini 3.0 i7 with 16 GB RAM and a 500 GB SSD. I was getting an occasional stuck note with the older one. The new one is rock solid. Some of my patches may have up to a dozen channel strips mapped to three keyboards. The Mini is mounted in a rack next to a MOTU Ultralite Hybrid. It is a good idea to map a panic button on your keyboard to controller # 123(all notes off). Also, you might want to invest in a battery backup power supply(APC, Cyberpower, etc.-$40-$60) to protect your Mac against power loss, which can damage you hard drive.

Multiple version of JRE in company..How to manage? (newbie question)

Greetings..this is a newbie question
We have 48 versions of JRE running in on XP IE6 in our company.
Some version beat up other JAVA applications.
It's a mess.
How can anyone manage this many versions?
Can we consolidate down to a few versions?
I saw some posts on changing the JRE dynamically or perhaps using a wrapper with a product from "sourceforge".
Are these viable?
Thanks in advance

How can anyone manage this many versions?you don't, each computer should periodically upgrade (IMO) but you shouldn't care. if you do, tell your users to load the latest version

Newbie question - XML version, searching by artist

Probably quite a common problems - apologies for newbie questions.
I've changed the URL of my MP3s in my XML to a new location and refreshed my feed. Is there a way of seeing what version of the XML iTunes is using? (it takes around 24 housr to refresh, right?)
Also, when I'm searching for my podcast by author it's not coming up (<channel><itunes:author>) - is there a reason for this or a way to get it to show up when people search for the artist, other than doubling it in the title? (This works by the way, but I'd prefer not to!)
Thanks.

you can do it in just one loop, going through all the image
tags in index_content and for each tag fill the values of all four
arrays
for (i...) {
get the appropriate child of index_content
first_array[ i ] = value of first tag
second_array[ i ] = value of second tag
no need for multiple loops.
flash has functionality for xml files, but it helps to write
a little wrapper around it, to simplify programming, especially if
you work with xml a lot.. I wrote my for work, so I can't show it
to you, but it's not very complicated to do

Transfer of custom control property one exit to another exit

Hi expert
    I have created one custom control in the exit EXIT_SAPLCOKO_005 for entering long text (TCODE : COR2) and I want to transfer
    the same custom control propert to exit EXIT_SAPLCOKO_006 .How can i transfer this.In this case the scope of custom control
   in that exit only.I want the scope of the custom control inthis exit also EXIT_SAPLCOKO_006.How can I solve this issue.

Hi,
Now we can use the soa mapping badi /sapsrm/bd_soa_mapping method
map_backend_to_xi to resolve the scenario.
If SOA is used to transfer PR, I am afraid that we have to use SOA mapping badi /sapsrm/bd_soa_mapping method MAP_BACKEND_TO_XI to realize your requirement.

Newbie question: ""dynamic"" casting

Hello all,
 
I have a quite newbie question. I have this class hierarcy:
 
A
|_A1
|_A2
|_A3
|_A4
|_A5
|_.....
 
in some part of my code I have this:
 
if (object1 instanceof A){
if (object1 instanceof A1) {A1 object2 = (A1) e;}
 if (object1 instanceof A2) {A2 object2 = (A2) e;}
 if (object1 instanceof A3) {A3 object2 = (A3) e;}
 if (object1 instanceof A4) {A4 object2 = (A4) e;}
 if (object1 instanceof A5) {A5 object2 = (A5) e;}
object2.callMethod();
 
Is there any way to do this type of casting just in one line? I mean, I just want to cast object1 to the class it is instanceof. If it is instance of A1, I want to be casted to A1, if it is A2 to A2, etc...
 
Thanks you in advance.

In fact I know what object1 is on execution time,Which doesn't help your compiler at all, when it's task to link and verify method calls.
because the code posted at the top is working well, i just want to avoid repeating that if's for all the new classes Ax I will create. Big "code smell" here.
In other words if i had from A1 to A200 i dont want to have 200 if's to cast it to the class it is and then execute it's method.You could call the method "doMagic()" and make it abstract in A. Then you can implement it in all Ax classes and would never have to worry about casting in the first place, because A.doMagic() would automagically do the right thing. Polymorphism.

Variable accessibility: newbie question

My next newbie question:
The following two classes are in two separate files in the same a folder testClass2:
package JavaDemos.testClass2;
import java.awt.*;
public class Sketcher {
    static SketchFrame window;
    static int widthXXX;
    public static int getwidthXXX() {
        return widthXXX;
    public static void main(String[] args) {
        window = new SketchFrame("Sketcher");
        widthXXX=1000;
        System.out.println("output: width = " + widthXXX);
        window.setVisible(true);
        window.specialReport();
package JavaDemos.testClass2;
import javax.swing.*;
public class SketchFrame extends JFrame {
    public SketchFrame(String title) {
        setTitle(title);
        setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE);
    public void specialReport(){
        System.out.println("number " + widthXXX);
        //     System.out.println("number " + Sketcher.getwidthXXX());
}They don't compile.
I get the following error message:
JavaDemos/testClass2/SketchFrame.java [23:1] cannot resolve symbol
symbol : variable widthXXX
location: class JavaDemos.testClass2.SketchFrame
System.out.println("number " + widthXXX);
^
1 error
Why isn't widthXXX directly accessible from SketchFrame?
Thank you again in advance for any help.

Why isn't widthXXX directly accessible from
SketchFrame?Because it's a class variable of another class. You have to refer to it as Sketcher.widthXXX.
