Beginner needs help with SimpleReadWrite

After reviewing the NI-488.2\Examples\DotNet3.5\SimpleReadWrite\vb (which works fine) in "step" mode I can not yet discover the command which

sends information on the device string. If I declare: BoardID As String = "0" Dim, Dim PrimaryAddress As String = "13", Dim SecondaryAddress As String =

'0', Command1 dim As String = "* IDN?" what comes after?. Is this the right approach? What else do I need to know, and where and how I can find it?

You did not add the assemblies to your project references list, as I have indicated in my note at the end of my answer lat. This is done through the project-> add a reference... menu item. Be sure to select the assemblies that are located in the folder of VS2008, where you have installed the support for multiple versions of .NET. This is distinct from the required Imports instructions. The Imports statement allows to simply do not have to write the full name of the class. So, having a NationalInstruments.NI4882 import you can declare a variable as

GpibDevice private as a device

instead of the full name

Private GpibDevice As NationalInstruments.NI4882.Device

What about the ReplaceCommonEscapeSequences error, well, you actually have this function in your form. This copy of the SimpleReadWrite example function.

You should check that your device is expected for the command. Require a carriage return after the order? Require a line break? If so, you must change the definition of Cmd1 to include these characters, as is done in the SimpleReadWrite example.

It's just to make life 100 x harder for you. The above errors would have been clear, if you knew how to program in VB.NET.

  • Flash beginner needs help with Movie Clips/Action script

    HI -.

    I'm having a problem with my video clips playing simultaneously and cannot, for the life of me, know what I did wrong. I'm new to flash so I can I have created something wrong but this is what I have so far:

    11 layers, total: 1 layer with 10 buttons, each button with the following actionscript code:


    on (release) {}
    gotoAndPlay (85);
    }


    When the number changes with regard to keyframes, the next film is about.

    I have 10 films, total, but they are only video clips, mainly photo slideshow with audio, does everything in the library.

    The problem occurs when I click on the second or third button. Not only the movie I selected starts to play, but all previous clips are as well, he has completely blurred all the sounds. I don't know what Miss me in action script, as my Action layer has a stop command to this topic at each keyframe where there is a new clip to play.

    I tried to add a stopAllSounds command, but I'm afraid that does nothing because it is not an "audio file" in itself playing in the timeline panel.

    I'm at the end of my rope and really need help to understand this one. My project is hanging in the balance on this point, I wrote everything correctly and it works beautifully.

    Help, please!

    Thank you

    Start your sounds in frame 2 and place stopAllSounds() on each keyframe where begins a movieclip.

  • Flash CS5 beginner - need help with Add URL link animated banner

    I apologize if this is a very basic question, but I am a newbie in Flash design. I created a basic animation in Flash CS5 and I need to add a clickable URL link. I tried a few tutorials that seemed promising, but none of them solved my problem. I tried a number of things, including the conversion to parts or all of the simple images buttons or movies and linking them this way as well as type in the code ActionScript 2 and 3, which none was successful. The animation plays correctly in my browser, but when I click it, the link does not work. I wish that the entire banner clickable to take viewers to the website linked instead to use the text of the hyperlink. Also, when I open the Code snippets window, it is empty, any image or image I selected. Do I need to import snippets of code somewhere or just will I things the wrong way? Any help is greatly appreciated!

    go to your help section and search the reference Guide of Action Script 3.  It is the repository of all the possibilities of ActionScript with Flash and Flex.  You can consult the alphabetical index URLRequest and navigateToUrl.  There could even be code samples included.  I haven't looked right, but you'll probably get before doing so.

  • Beginner needs help with Aironet 1131 G Wireless Access Point

    I have a new Cisco Aironet 1131 G wireless access point.  It takes an IP address and I can ping this address.  However, I can't access it via the graphical user interface based on the web or the CLI.  I preformed reset.  Any suggestions would be greatly appreciated.

    Thank you.

    Hello

    I can't access that means? you are not able to go to the CONFIG T of the CLI prompt? and if you are in the same subnet as the AP, are you not able to open to the top of the GUI? If you are not able to then, with the command 'show version' on the AP CLI and see if your image is "RCVKW8". If so you will need to convert the same IOS using the method below.

  • Beginner, need help with ActionScript 3.0

    Hi all
    I am a newbie to flash and have little experience with OBJECT oriented programming (and therefore of action script), so I apologize in advance for my lack of knowledge. I think it is easy enough to fix, just don't know the syntax or if there is a better way to do it. Here's my problem:

    I created a flash file which has a card (like a layer of the base image) with 4 quadrants, I created separate layer (converted to a button) which corresponds to the limit of 1 of the 4 quadrants, and added a simple script, I copied and modified since a tutorial Adobe (see syntax). Instead of a new webpage to appear and the text output "I clicked" I want a new window appears with the plan of each quadrant (which is another image, jpg).

    I don't know what is the syntax to call this new image upward once your mouse over individual quadrant.

    Thank you

    Try this code. It should simplify what you want to do. Just replace the real names of new html documents that you want to open.

  • I'm suddenly needing help with my browser Firefox (6.0.2)

    Hello
    I'm suddenly needing help with my browser Firefox (6.0.2)

    (OS: I use Windows XP).

    When I open the browser, I don't see is a totally white screen of white, with all the toolbars at the top.

    I know that my physical connections are very good: I have tested the modem, turned the pc market etc and I can also receive/send emails.

    This problem started today, September 8, 2011 and has never happened before.

    Is it a coincidence that Firefox itself to day before I disconnected yesterday evening? Could this be something to do with this particular new update?

    I also noticed that just before I "opened" Firefox, I now get a small box indicating:

    [JAVASCRIPT APPLICATION]
    Handl exc in Ev: TypeError: this oRoot.enable is not a function

    This never appeared before - I hope that it offers a clue has what is wrong.

    The browser not be stuck in Mode safe, said by the way.

    Of course, I can't find solutions to the problem on the internet, I don't physically see all Web sites!
    (A friend sends this request in my name from their pc)

    Any light you can throw on this problem of confusion would be much appreciated. I'd rather not have to uninstall and reinstall Firefox if possible.

    If the only option is to uninstall Firefox and reinstall from your site, I'm also in trouble (I can not see the internet or download).
    In this case, would you be able to send the .exe file as an attachment to my e-mail address? In the affirmative, please let me know and I'll give you more details.

    Thanks in advance.

    One possible cause is security software (firewall) that blocks or limits Firefox or plugin-container process without informing you, possibly after the detection of changes (update) for the Firefox program.

    Delete all rules for Firefox in the list of permissions in the firewall and leave your firewall again ask permission to get full unlimited access to the internet for Firefox and the plugin-container and the update process.

    See:

    Start Firefox in Firefox to solve the issues in Safe Mode to check if one of the extensions of the origin of the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > appearance/themes).

    The link below is a guige to install a video card in your Pc.  In particular, it seems that you will have to perhaps specify the location of the new card in the bios and save this change before you install the new card - see step 4 in the guide on the link below.  If your new card fits into the PCI Express x 16 slot, you will need to define PCI Express in the bios and save the changes.

  • I need help with an installation failure to interpret and troubleshoot a Setup log.

    Background: A few years ago, many editors of cinema used Final Cut Pro 6 (also contained in Final Cut Studio 2) for their editing projects.  Shared Apple Final Cut X uses a different format that is not compatible with FCP6.  Sometimes, these editors are called to work on a few historical projects that have been published in FCP6 and need this version to run now.

    Starting with OS X Lion, FCP6 would install not in Lion and thereafter.

    According research by Jeremy Johnston as noted on his blog, he discovered that Apple has inserted a file in the folder CoreServices in the Library folder of the system folder that causes versions the version Final Cut Pro X (and other older Apple programs in the same situation) do not settle.  He suggested changes to this file that would seek to prevent interfering with the installation of FCP6 in Lion, many users of final cut PRO 6 were successful in their efforts to install in Lion and work with it.

    Later in a discussion update on installing FCP6 in Mavericks, HawaiianHippie determined that the simplest way to perform the installation of FCP6 was simply copy this file and remove it from the system folder, install FCP6 and then restore the copied file:

    https://discussions.Apple.com/message/26309669#26309669

    I used this method with success to install FCS2 in Yosemite:

    [click on images to enlarge]

    However, in my attempts to install FCS2 in El Capitan, it fails in the last 5% to install the first DVD:

    First of all, I need advice on how to display an extremely large Setup log in this thread (on MacRumors, it is a method to insert a 'code' in a small box that can be the object of a scrollbar if necessary to read all along).  I am unable to find such a method to post here.

    Then once approved, I need help to determine which component is causing the installation to fail and perhaps this element can be omitted from the installation:

    If this element is not required, then maybe FCP6 can be installed successfully without it.  And if that omitted element is necessary, perhaps a manual method to install it can be determined by pacifists.

    It is my goal to help those who need to install and use FCP6 on their new Macs running El Capitan.

    Here is the post on MacRumors with pre-installed Setup log:

  • Need help with the port forwarding for a XBox remote Streaming

    I have a router R6200v2 and need help with port forwarding.

    I came across this set of instructions for setting up stream port forwarding XBox remotely from anywhere

    http://kinkeadtech.com/2015/07/how-to-stream-Xbox-one-to-Windows-10-from-anywhere-with-Internet/

    I have no idea when it comes to such things and I want to make sure I do it correctly without messing up my existing home network.

    Port Forwarding and triggering Port pages setup look very different from what the guy uses. Can someone walk me through what I do to set up please?

    Hi @varxtis,

    You must enter them in the field for a start external Port and external completion Port. You will need to send individually except for the range of 49000-65000. The steps are as follows.

    1. create a Service name (it could be something else that you cannot use the same service name twice. Ex. XBOX1, XBOX2 and so forth.)

    2. Select the type of service (TCP, UDP or both)

    3 entry 5050 times a start external Port and external endpoints.

    4. Select the IP address of your XBOX.

    5. Select apply.

    6 do the same for other port numbers. To the beach, use 49000 for the external departure Port and for the external completion Port 65000.

    Kind regards

  • Need help with network home using Airport extreme

    I need help with my home network.  I'm not very aware when it comes to all things network.  Here's how my network is currently set up.

    Cable modem to Airport Extreme for Gigabit Switch.  Cables come out of the switch to all areas of the House.  I have 2 other extreme airport connected in other rooms of the House directly on the wall that dates back to the switch.  I hope I am explaining that properly.

    My problem is that this seems to have caused some of my connections cable does not work.  When everything is configured, it has worked well.  All connections in the House worked.  Then we have disconnected one of the extreme airport and moved to another location in the House to have the best wifi coverage.  Since that time, a lot of the ethernet wall plugs are not working.  For example, when I plug in my Macbook Pro in making ethernet in my kitchen, it says connected but it has an assigned ip address and cannot connect to the internet.

    Any help you can provide would be great.

    I would like to get the return tech to help you to...

    But it is likely that something (or someone) has tampered with the settings.

    The layout is fine... but you can cause problems with the network by creating a loop.

    This can happen because the AE you moved is connected wrongly... somewhere in the network it is connected to the switch again.

    Or AE is set to expand wireless... It's FAKE... It will loop the network on the back main EI wireless.

    Unplug the two AE you have that function as extensions...

    Turning off everything else... then it works again...

    Do it in this order.

    Modem... Wait 2 min

    AE... Wait 2 min

    Switch.

    Now check that the network is working properly... power of customers in various locations and make sure everything is good.

    If so, then manually reset the two AE of factory and redo their installation.
