hey, i need to get started on labview. i have to make an interface in which i have to make a program to send a voltage to a machine

well you could start by telling us what the name of the machine is. What type of interfacing does it have. does it already have ready made drivers.
These are just a few things we need to know.

Problems getting started with LabVIEW FPGA

Two (probably) related questions:
1. I am trying to get started with LabVIEW FPGA, and I am having trouble using a host VI to test my FPGA VI. I started with a basic QAM modulator VI, to be run on the FPGA, and I have reached the point where I need to verify the logic and timing with this VI running on the development computer with simulated IO. I have tried various combinations of putting the code inside single-cycle timed loops vs not; putting the modulator block directly into the host VI, and using the "FPGA reference" block. When neither the host VI nor the modulator VI use a single-cycle timed loop, I see correct behavior. In every other case, the output of the VI is either absent or incorrect. I need to use a single-cycle timed loop in the FPGA VI to properly verify timing behavior (as far as I know), so the one functioning case is not enough for me.
I'm sure there is a key step I'm missing or misunderstanding, but I have not been able to figure it out myself yet. I've attached my modulator diagram as well as two different attempts at host VIs. I can share other information, but I'm not sure what is most relevant.
2. I am also trying to test a simple wrapper VI for the Xilinx FFT block, and I am having trouble accessing FIFOs inside the host VI. I thought this would be relatively straightforward, but when I tried to change the "method" on an "invoke method" block, there were no options for accessing FIFOs, as I understood there should be. This is a total roadblock for me. These two diagrams are also attached, the test diagram shows the options available to me for the "invoke method" block.
Labview 2013, PXIe-7965R, PXIe-8133 controller.
I had to combine the diagram images; in case they are hard to follow this way, see the individual images here: http://imgur.com/a/oB6OD .
Thanks in advance for any suggestions.

Hello Monguin61
If you are having problems reading from DMA FIFO's you should test them using a very simple code to understand their behavior. First, you could start taking a look to the linked documents:
Reading DMA FIFOs from Host VIs (FPGA Interface)
Using DMA FIFO to Develop High-Speed Data Acquisition Applications for Reconfigurable I/O Devices
FIFO.Read (Invoke Method)
Then you could test and analyze a simple example to understand how it works, for example this one: Simple DMA FIFO Example for FPGA.
Check the references when you are using DMA FIFO's, I noticed you did not connect them in the second picture attached.

Error, in Getting started with Labview. Chapter 3, part 4.

Hi.
Still struggling on, trying to find the time to work through the "Getting Started with LabVIEW" document.
Only 19 days left to go, and I'm still only in chapter 3!...
Right. In the "Saving Data When Prompted by a User" exersise, part 4...
4.   Right-click the Signals input of the Write To Measurement File
      Express VI and select Insert Input/Output from the shortcut menu to
      insert the Comment input.
Problem is, that option is greyed out, so not available!...
I did what the instructions said, I right clicked on the "Signals" input, and it doesnt do what it says on the tin!
Any pointers?   Please don't mention search the help, I've crashed the entire LV environment 3 times now, trying to search for something in there. It's OK if it finds someting, but it seems to bomb at times, when there is some ambiguity when searching.
Also, I won't be able to do anyting with any replies for a day or two, as I have to go up country to a customer, and mess about with hot oil, high volts, and lots of RF. It never ends.   (I've still got the day job to do, while trying to fight my way through this "evaluation". 30 days of "Use" would be better, than 30 calendar days for some of us.)

OK... Who let the smoke out?

Hi Dennis, and everyone else..
That is not how it looks when first dropped on the BD. On my machine, it is partialy expanded by default, after you clear the Configure dialog that pops up ocupying most of the screen.
Again, if it makes a difference to the way the Right Click shortcut menu works, it should be documented in the Getting Started document, especialy as it seems to be a critical point.
OK, explain this...
I've just rubbed out the save to file VI, cleaned up the broken wires etc, and then planted a new one on the BD. Once I cleared the Configure dialog that covers up most of the screen before you see it the first time, the VI was partialy expanded. I forget the exact list, but "Signals" was not at the top.
I did *EXACTLY* the same again, deleted it, cleaned up, and then planted a fresh new one. That DID appear that time with nothing but the "Signals" item showing, and two down caretts below that, indicating more items.
So......
Why the different behaviour each time, on the same BD, in the same session. Some underlying working data not being correctly initialised when invoked? Of course, that never happens, right? ('C' programmes eh?)
Trying some more, it seems the behaviour loosley depends on just how close to the edge of the While loop grey border you place it.   Odd.   I have a 1280x800 screen to play with, and a 1280x1024 second screen I use for the Getting Started document. That is the absolute maximum I can have, due to hardware limits.
I also find, that if you fully expand the "Write to Measurement File" VI block, then fully collapse it, then expand it again, all the items in that list have changed places! Why?
I had noticed earlier that there is no uniformity in the layout of even the items common to many if not all VI blocks (error in, and error out to name but two) Sometimes one is above the other, sometimes the other way round, sometimes they are not even ajacent to each other. Has that been done as a source of minor ammusement or something?
Talking to another colegue here, who just wandered in to see how I was getting on with this. Seems he also has tried the introductory entry into LV (V8.something) in the past. But he too, found too many things that behaved differently from one time to another, so abandoned it as a lost cause, then decided to learn how to use Visual Basic with NI-GPIB IO instead.   Not without issues either he said, but at least it all behaves exactly the same, each and every time.
End of the day now...
Regards.

What software do I need to get started with GIS development

Hello, I'm a Oracle RDBMS specialist but interested in getting into GIS development. I want to set up a local environment and play around with it. Could someone advise me as to what software I need to install/download? Is all of it free?
1.) I'm assumming I need ORACLE with SPATIAL (was looking into 10g) Is this download free?
2.) I also looked into MAP VIEWER as an extension of the Oracle Application Server.
Are these 2 products all I need to get started?
I also read alot about arcGIS? Can this product be downloaded for free or is it a licensed product?
Does anyone have any other suggestions about some software/documentation that may help me get started in this technology.
Thanks,

Hello!!
Actually, you need Oracle Spatial or Oracle Locator. Oracle Locator is free on Oracle Express, and you could start with it. Otherwise, if you want to know more, Oracle Spatial comes with Oracle Enterprise, and Oracle 10g gives you a schema that allow you to store, manage and query spatial data through Oracle functions, etc.
To start using MapViewer, considering that you already have some spatial data stored on the database, you could download the MapViewer kit at http://www.oracle.com/technology/products/spatial/index.html.
You could buy the Pro Oracle Spatial book. It´s very good.
Good Luck!

Welcome back. Do not overlook the Finder and individual application Help menu support. The links provided above are great starter references. With tongue in cheek, they also may not be as current as the OS X release on your mini, so expect some differences.
Here are a litany of keyboard short-cuts, last updated in June 2012, that may prove selectively beneficial.
For actions like copy(c), paste(v), cut(x), print(p), and select-all(a), substitute the command key instead of control key.
If you right click on a file, this menu will seem familiar. Press the option key and notice the menu changes. If you copy a file(s) from this menu, change to the destination and then press option with the right button menu to see copy file(s) changed to move file(s).
To quickly view a file's contents, left click on the file icon, then press the space bar.
The native file format for OS X is PDF. Thus, when you choose to print, you also have the option to save as PDF with web links preserved.
Enjoy your mini.

In response to below------Thank you Lynn-----Yes, there is a main panel--I will attach----and if you have any further suggestions please let me know--Thanks again
How are you running this program? Is there a top level vi which calls the ones you posted? The Display image on screen.vi will display two images in succession, but according to the note on the block diagram the second image is blank. It seems as though this would intentionally create a flicker.
The sequence structure is unnecessary. Dataflow will determine the order of execution. The only exception is the time delay in the third frame. Since it has no data dependency, a single frame sequence may be useful to assure that the delay occurs before the picture is updated. A simple state machine might be a more versatile architecture for what you may be trying to do.
It is not necessary to write the FR.PanelBounds property immediately after reading it, nor is it necessary to read it a second time in the second frame. Just wire from the first read.

Need help getting started -Editing software

Hello everyone
I need to get started with video editing on a Mac -
I didn't touch an editing software since 1998 , it was premiere 4.2 on a PC !
And didn't keep up with what's new but i'm now using a Mac!
I assume now most software allow realtime rendering, and have great tools !
So, I'd like to put together a holiday movie I shot on a DV camera-
once finished , it would either play from the computer connected to a Video projector AND / OR burned on a DVD .
I'd like to make something a bit creative : Split frames / moving Titles accross the screen etc...
my questions :
-If possible, I'd like to minimize the rendering process ( realtime?) What is a good editing software Imovie / Final cut ( which one?) / Premiere ?
-What can I use to create split frame ( video)
-What can I use to create moving titles ? ( important)
-Can this be achievable on a Macbook 1,83GHZ / 2GB of RAM/ 250GB EXT. Harddrive FW.?
Thanks for you inputs ( Open subject )
David

You don't need timecode to make frame accurate cuts.
You simply play or drag the playhead to roughly where you want it and then use the left and right arrow keys to move frame by frame to the exact frame you want.
Incidentally if you hold down the Shift key, each touch of the arrow key will jump 10 frames.
iMovie has a tremendous amount of potential which may be hidden away at first sight.
Take a look at those fantastic and easy to produce titles - the hardest part is typing the letters!
Incidentally, even FCE does not display the original tape timecode natively.
Ian.
P.S. The best way to unlock most of its secrets is to get a book. Most good libraries usually stock them or can get them for you.

Depending on the age of your machine and the version of iPhoto, you may be able to download it from the App Store - but you'll need her account details to do so.
Other than that you'll need to purchase it on the App Store.

You need a valid payment method even for free items. If you know the payment method is valid then contact iTunes.

Help Needed with getting Started With Office 365 Development C# Rest API

We have a O365 Tenant Setup with a Federated Active Directory Setip we want to be able to right code that will connect to our tenant and perform basic CRUD operations against it (ex. Creating mail boxes)
The problem is we want this to be contained in a CLR trigger In SQL so say if a new user is added to our user table then we would create a new AD account for that user and also create a mailbox.
But I cannot find and example on how to connect to Office 365 using the REST API (Not the SDK because you can not add the connected service to a class library) and before the required actions that we need to do. All the example I have found are with the
SDK API and/or require window 8 and that is also not an option.
Please help I do not know where to start, and I would love to see some examples done in c# and not using the SDK.
Thanks,
Andrew Day

Hi,
>> Instead of SharePoint URLs I would use the O365 API URL?
Yes, in my sample code, I was accessing the File resource by using the O365 File API. In your case, you need to acquire the token to access the Mail resource and use O365 Mail API.
By the way, I think the article
Understand Office 365 app authentication concepts will help you to understand the authentication process in Office 365 Development.
>> Why can I not use the SDK API with a class Library?
Actually, you are able to reference the Office 365 .NET SDK in the class Library. But the class library project type was not supported by Visual Studio Office 365 Development Tool. As a workaround,
you can reference the SDK manually in your project.
Since your original question is about “getting started with Office 365 Development C# Rest API”, if you have more questions about the Office 365 SDK, I will suggest you posting a new thread
to discuss the Office 365 SDK. It will involve more other community members to share their ideas and experience on a specific a question and for others who had a similar question could also find the valuable information quickly.

New to CF: What do I need to get started to update a website developed in CF?

Hi. I have been asked to update a website that was developed in Coldfusion and I am not sure how to get started. I'm very familiar with HTML and I've been studying CFML. What I need to know now is how to get started. The website is not live yet and I need to make some changes to the content. I have Dreamweaver and I know I can download Coldfusion. Can someone please explain to me what needs to be done next? After I download CF then what? How do I make changes and save them on a site that isn't live yet? Do I need to go live with the site before I make changes? Is it possible to connect to a ftp server of a site that's not live yet? The site has a domain name that's registered.

BagelBites wrote:
How do I get my changes to appear on a site that has already been developed but hasn't gone live yet?
Publish your changes to that site.
How you do that depends on what connection types you have to that site. This might be done with FTP, WebDAV, Network File access or other methods.
How you view the changed content will also depend on what you mean by 'gone live'. Is there a Domain name that points to the content? Do you know the IP address? Is there some temporary Domain Name? I have used all these methods and others in the past, depending on what I was working and how it was being hosted.
These questions are most likely more definitively answered by talking to the system operators of whom ever is maintaining this web server for you. If this is a hosting company, they may have common answers to these types of questions in a FAQ or other documentation. If not, directing the questions at their customer support channels should yield appropriate results.
If this is not true, then my strongest suggestion would be to find a better hosting solution!

Need help getting started - I am a newbie and am royally confused

I have Crystal Reports XI and VB.Net 2005 with CR functionality built in. I created reports directly in CRXI and now need to be able to use them in .Net.
Here is where I get lost. When I created my RPT file it had me connect to a database (Access 2002) and then add a table and fields. It works great except now that I am porting to my .Net app the database it needs to connect to will always be changing (dynamic). The table and field names will always be the same. It is just the file name that changes, based on user inputs.
So are there any tutorials, literature, help that anyone can point me to so I can get on with my steep learning curve? I started programming in VB.net and developing CR's just a short time ago and would appreciate a 'dumbed' down explanation so I can get a handle on this.
Thanks for any help or advice offered.
