Some DSC developing relating questions

Hi,
I am new with DSC and have some questions relating to building the custom periodic I/O DSC server:
1. After building the custom VI and implementing it as an I/O DSC server, I found there are some mistakes inside the custom VI. I would like to modify it and rebuild it. But all of the shared variables are bound to this server. What I did is I deleted and removed these variables and rebuild them again. It takes a lot of time when I want to modify this custom VI. Is there anyway to avoid it?
2. To communicate with the custom VI, I use some controls and indicators. But to program a VI sometime I need to initialize or change the value of controls. But the guidelines for creatin a data access VI, I cannot use the local variables, property nodes, or control references for those controls need to be public. I would like to know if there is any solution to program effectively in my situations?
Thank you,
Thang

Hi - I'd like to clarify the issue you are having in question #1.
Here's what I think you are doing:
1. You write a VI with some controls and indicators wired to the VI's connector pane.
2. You use the DSC "create periodic I/O wizard" to create the server VIs.
3. You open an empty project and right-click "My Computer" and select "New->I/O Server". You then select "Custom VI - Periodic" from the list and click "Continue".
4. You see the name of the VI you created in step 2 under "configuration name" pulldown and click "OK". A new library appears in the Project Explorer called "Untitled Library 1".
5. You click the "plus" and see a globe on a hand icon with the name "Custom VI - Periodic1" or something similar related to your VI name.
6. You right-click on "Untitled Library 1" and select "create bound variables". You then navigate down through the tree structure to your server inputs and outputs and select them and add them and then click OK.
7. The Multiple Variable Editor pops up showing the new variables. You click "done" and see the new variables listed in your project explorer window.
8. You use these variables on your Client front panel by dragging them from project explorer onto your VI front panel where they work ok.
9. You want to make changes to the VI server, and rebuild it, and update your Client VI. Rebuilding the VI server is no problem. I don't think you will have any problems as long as you haven't added or changed any variable names. If this is what your question #1 is about, then there are several different ways to deal with this using the multiple variable editor, or the front panel mass binding editor.

Considering buying time capsule have some Mac address related questions

Hi,
as mentioned above I'm considering buying a time capsule for backup and wifi purposes.
My internet providers connection depends upon a set Mac address from the first computer you register with, the system works with any router which then clones the MAC address and issues a wifi signal to all computers. I don't have access to the origional computer which we registered our connection on, it went to the great computer graveyard in the sky and I have no record of the Mac address.
I Would like to use the time capsule system as a router and remove my existing router. my questions
can the time capsule spoof or clone a Mac address ?
I Don't want to be offline while we deal with technical support as they are quite inept sometimes.
Is it in this case really plug and play ? Can I just plug it in set it up on my Mac and away it goes where other non Apple devices can use the wifi.
Without the existing router the cable that comes into the house connect directly to the ' original ' computer and the Internet only works on that computer
hope someone can help me I would like to purchase this device

I want to check all functions of PCI 6534.I have read the user manual..I have some memory related questions.Please help me for that.

I want to check all functions of PCI 6534.I have read the user manual..I have some memory related questions.Please help me for that.
1.)If i am using the continuous output mode.and the size of generated data is less than 32 MB.If i want to preload the memory,what should i do?I want that first of all i load all my data to onboard memory & then i want to make start the transfer between 6534 & peripheral.Is it possible?As per me it should be.Plz tell me how should i do this?I think that in normal procedure the transfer between 6534-peripheral & outputting data from pc buffer to onboard memory works parallely.But i don't want this.Is it poss
ible?
(2).Similarly in finite input operation(pattern I/O) is it possible to preload the memory and then i read it?Because i think that the PC memory will be loaded automatically when 6534 acquires the data and then when we use DIO read vi the pc buffer data will be transferred to application buffer.If this is true,i do not want this.Is it possible?
(3) One more question is there if i am using normal operation onboard memory will be used bydefault right?Now if i want to use DMA and if i have data of 512 bytes to acquire.How will it work and how should i do it?Please tell me the sequence of operations.As per my knowledge in normal DMA operation we have 32 Bytes FIFO is there so after acquisition of 32 bytes only i can read it.How it will known to me that 32 bytes acquisition is complete?Next,If i want to acquire each byte separately using DMA interrupts what should i do?Provide me the name of sourse from which i can get details about onboard memory & DMA process of 6534 specifically
(4).In 6534 pattern Input mode,if i want to but only 10 bits of data.and i don't want to waste any data line what should i do?

Hi Vishal,
I'll try to answer your questions as best I can.
1) It is definitely possible to preload data to the 32MB memory (per group) and start the acquisition after you have preloaded the memory. There are example programs on ni.com/support under Example Code for pattern generation and the 6534 that demonstrate which functions to use for this. Also, if your PC memory buffer is less than 32MB, it will automatically be loaded to the card. If you are in continuous mode however, you can choose to loop using the on-board memory or you can constantly be reading the PC memory buffer as you update it with your application environment.
2) Yes, your data will automatically be loaded into the card's onboard memory. It will however be transferred as quickly as possible to the DMA FIFO on the card and then transferred to the PC memory buffer through DMA. It is not going to wait until the whole onboard memory is filled before it transfers. It will transfer throughout the acquisition process.
3) Vishal, searching the example programs will give you many of the details of programming this type of application. I don't know you application software so I can't give you the exact functions but it is easiest to look at the examples on the net (or the shipping examples with your software). Now if you are acquiring 512 bytes of data, you will start to fill your onboard memory and at the same time, data will be sent to the DMA FIFO. When the FIFO is ready to send data to the PC memory buffer, it will (the exact algorithm is dependent on many things regarding how large the DMA packet is etc.).
4) If I understand you correctly, you want to know if you waste the other 6 bits if you only need to acquire on 10 lines. The answer to this is Yes. Although you are only acquiring 10 bits, it is acquired as a complete word (16bits) and packed and sent using DMA. You application software (NI-DAQ driver) will filter out the last 6 bits of non-data.
Hope that answers your questions. Once again, the example code on the NI site is a great place to start this type of project. Have a good day.

IOS developer program question

I'm sorry if i'm in the wrong area of this forum to ask this question. I would like to register to the iOS developer program. If I'd like to unregister how would I do so? Would the easiest way be just not to renew the membership?

I don't know your situation, exactly, sorry. I don't know of anyone that just wanted to walk away. The dev account is tied to your iTunes account, etc. So to some degree, you'll still be active as long as you interact with Apple.

Actually, we cannot (at least anymore) directly email the team. I tried and got a reject from the mail server. So, I'm going to post here so I can feel better knowing I said something and then I can get back to programming :-)
Ok, I’ve been developing Windows apps since Win 3.1 (yeah, a long time) and have always admired the Microsoft attitude towards Developers and it’s desire to educate and empower R&D.
So, I’m wondering what’s going on? Why am I being asked to have an account to develop anything for MY own PC? Why am I being asked for my Microsoft account password, repeatedly, when I’m just looking up documentation on UserControl or C3 keywords…
repeatedly? This is nothing short of annoying and it gives me pause and concern about the ecosystem. Is the plan to lock down programmer’s capabilities, knowledge and tools?
I’m involved in the TAP program for Windows 10 and have voiced concerns in the same category with regard to installation and deployment of Universal Apps. Security is not a reasonable excuse. Some of us love to program and actually
control their PCs. We are not planning to sell everything we write on the Windows Store. What happened to programming something cool for your home network or just for friends? We need, and used to have, Microsoft’s support in doing
this sort of thing. Documentation and tools are more important now than ever. I’m saddened to see the direction things are heading…
If there is a sane reason I’m being badgered to ‘log in’ to read .NET documentation every hour, please share. If not, please consider lobbying to get things back on track.
Thanks

HT201272 I have recently picked up an Apple TV. When I go to the movies tab, there are less movies available there than there are in my i-Tunes account. I've done some looking around at questions from others, but haven't found an answer that works for me.

I have recently picked up an Apple TV. When I go to the movies tab, there less movies available there than what is available in my i-Tunes library. I have 38 movies showing in my library but only 23 are showing in the Movies tab on the Apple TV. After researching this a little, there are only 23 movies showing under Purchased in the Quicklinks of my i-Tunes account. The majority of my collection are digital copy downloads that came from DVD purchases. Some of the missing movies were added in the past couple of months, the rest are a year-or-so old. I have done some looking around at questions from others, but I have not found an answer that will fix my situation. How do I update my library to get ALL of my movies to reflect that they were "Purchased"(as it says they were in their Properties)?

The pros and cons of to CC or not to CC have been done to death
Its a fact the CC model will work for some, especially newbies and small businesses.
The risks associated with the CC model have been well documented.
For long term users of CS perpetuals its generally a large hike up in cost compared to the upgrade system.
Then there are the....... Adobe can rot it hell...... group who will never subscribe
To each their own, you do the math to suit your cashflow whatever that is and then make an informed decision
To those on the CC model, I'd like to offer some practical advice.........do not allow automatic updates.........make regular backups............develop an exit strategy of alternatives for when you can no longer afford the subscription costs............never ever assume that the Adobe update is bug free
Enjoy your cloud

Thank you for that post, and the advice. I just happen to be one of those who it does work for. I've been around long enough to know that CC isn't going to work for everyone(the large publishing/radio/web company I work for isn't upgrading to CC because of the costs involved). But it does for me as I potentially venture out into the full-time freelancing world and away from the more structured big office environment. I can't make decisions based on what is best for anyone else, or what will hurt or help Adobe. Just what affects me, and that's all.

Some very "newbie" networking questions -- trying to get started

Hello all. Since this forum is so friendly for issues related to Arch, I thought I'd post my semi-arch related question.
I'm trying to create a network for my house, consisting of about 3 computers. I have a book reference, TCP/IP Network Administration from O'reilly, but I think I need a bit of a "kick-start" in order to get to a level in which I can comfortably understand the book (if that makes sense).
I've got internet access working by connecting to a router and having everything configured by DHCP (ie, in rc.conf, eth0="dhcp"). What's bothering me (and I don't even know if it should) is that the other computers on the physical network are not visible to me.
IE, when I try to connect to them with their host name, it doesn't recognise them. My understanding of that is that either I need to manually set the hostnames of the other computers on the network in /etc/hosts, or use something like a DNS server on one of the computers in the network in order to recognize the others.
My other doubt is that I think I've got a dynamic IP address (though it might be static, I'm not quite sure). Does that change things?
I don't expect you guys to completely run through me setting up the network (that's what the book is for!) but some basic advice on either my misconceptions (I'm sure I have plenty) or related in general to my situation would be awsome and highly appreciated. I'd also be happy to provide any additional info that would be helpful.
Thanks in advance.

My set up is simple.
I have a Linux router running on an old Pentium machine. It has two cards, one configured for the private network (with an address like 192.168.1.1) and the second card set up to take addresses from DHCP ( since that's how Rogers sends you the public address).
In that machine I run my firewall, SmoothWall (smoothwall.org) and have enabled NAT so the machines in the inside network can go to the Internet.
I have Samba set up in another machine to share files (that's an Arch system) with static IP, my daughter's machine (another Arch system), my system (obviously another Arch with static IP) and my wife's machine with Windows XP system (static IP too).
So, the key concept here are:
1. Use static IPs for the private network
2. Use DHCP for Rogers
3. Use NAT in your router so all the machines can go to the Internet but no one from the Internet can get to them.
Hope this helps.
R
p.s. feel free to contact me off the list if you need further details/help.
Aha! So, for example, the network 192.168.0.0 where mask is 255.255.255.0 is a private network set up by my router, right?
So the addresses in 192.168.0.0 never change, but the public IP address of the hosts do change?
Does that mean that if, for example, I have a host called 192.168.0.32 that its address never changes? Can I simply add that to all the other hosts' /etc/hosts file and it won't change?
All I was ever concerned about was allowing hosts in the network to contact each other via hostname. If that never changes then I'm all set.
BTW, thanks for your continuing help!

Why do some graphics only have question marks on my iPad?

Why do some graphics only have question marks on my iPad?

On web pages and in the ap store. In place of the graphic there's a little box with a question mark in it.
I can't even connect to a web page right now. I've got three bars on the wifi icon but safari just keeps trying until it says it can't connect to the server. Same with the ap store, I've been trying all afternoon to download a new ap with no success. It came right through on my iphone on the same wifi network. Had the same problem on my home network. I'm new to apple and I've only had the iphone and the ipad for a little over a week, but all this seems to have started after the most recent software update.
Is this all related?

Deafult search engine on a new tab-this thread was closed but I have a related question. Once you put the new url in, what then? Close? When tried, did not work

"deafult search engine on a new tab" - this thread was closed but I have a related question. [the word “default” is spelled as it on the thread] Once you put the new url in, what then? Close it? When tried, it did not work. The closest answer is noted here. Instructing to go to about:fig. Specifically, I installed the accuweather add=on and it took over my tab home page - the one that comes up when you click for a new tab. I didn't like it so I clicked the button to remove it and the page went blank. I searched to see out to restore the tab page, tired the reply at this page :

But it did not work. Can some on help me? Just want to know how to make google or some page open on a new tab.
Many thanks

Thanks so much for your support. As I said I am not a professional, so I by chance saw a friend who is and this is what he suggested and it worked.
We googled for an answer and found this site: http://www.guidingtech.com/8004/have-new-tab-page-open-specific-website-firefox-chrome/
It says to Download and install Download and install''' NewTabURL''' and gives instructions on how to. Now when I open the tab it goes to my preferred search page!

PM/EAM related questions posted in PLM forum

Hi,
I was going through some of the threads available in PLM forum, but to my surprise, most of the threads posted are related to PM, which should have been posted in EAM forum. It was clearly mentioned by the moderator in one of the sticky thread [PLM-Forumsplit - Please ensure you are using the right forum|PLM-Forumsplit - Please ensure you are using the right forum;
Questions regarding Plant Maintenance (PM) or Customer Service (CS) are discussed in the Enterprise Asset Management (EAM) forum
forums - posts will be moved to the right forum.
Please ensure your are opening a new thread in the right forum
Despite the clear instructions given my the moderator, PM related questions are still posted to PLM forum and some of the active participant of EAM forum answers these questions in PLM forum. It would be nice if those threads are moved to appropriate forum, so that the relevant informations are available under one forum, also, PLM forum should be monitored regularly and inappropriate threads are to be moved to their respective forum.

I had used abuse reports for some, but numbers of such posts are many.

I hate to say this, but I often see the same thing, and I've never been able to figure out exactly what triggers selectability vs. non-selectability, but I suspect some of it has to do with tranparency flattening in particular, and possibly text wrap in cases where that comes into play. ID optimizes the PDF it creates, I think, and that might cause text, or even images, to be broken into chunks in funny ways. It occurs to me that turning off optimzing for fast web view might help in this regard.

Bug in SQL Developer relating to handling of XMLTYPE columns

Hi,
I have found a bug in SQL Developer relating to its handling of XMLTYPE columns.
Given a table with the following data:
ID, XML_DATA
1, <xml here>
2, <xml here>
3, <xml here>
And the following SQL to extract a value from the XML and also an XML fragment as an XMLTYPE:
SELECT
EXTRACTVALUE(t.column_value,'/*/USER_ID/text()')user_id
, t.column_value user_data
FROM dbuser.mytable m
, TABLE(XMLSEQUENCE(EXTRACT(m.xml_data, '/*/USER_LIST/USER'))) t
I get the following:
user_id, user_data
jsmith26, (XMLTYPE)
mjones45, (XMLTYPE)
sborga31, (XMLTYPE)
Note that the user_id is correctly extracted, however the XMLTYPE column (user_data) is empty in SQL Developer.
The same query returns the correct XML data in TOAD.

Steve,
So your example is slightly more complex than the one documented for a table in the standard OE schema here:
http://docs.oracle.com/cd/B19306_01/server.102/b14200/functions052.htm
That example works fine on an 11.2.0.1 database with SQL Developer 3.2.20.09.87. Please try the following with your case:
Tools -> Preferences -> Database -> Advanced -> Display Struct Value In Grid (check it off if not already)If that still does not work for Run Statement (query result displayed in the grid, not as script output using Run Script), then please provide a test case based on the Warehouse table in the OE schema (or your case with DDL and DML scripts including the xml data) and I will log a bug.
Thanks,
Gary
