Action files

Hello world

Letssaywehave3differentchannelsandwewanttologallthedatafromthosechannelsintoameasurementfile. Itsprettyeasy. (seeattachedvi)

now, I want to add the ability to my vi which gives the user an option to select the channel to which it wants to write to the file of measures. In this case, we want to just channel 1 and 3.

I add a Boolean value to choose what channels I want to but the problem is when it is a case of false I need something assigned to the tunnel which means that he wrote '0' or 'NaN' in my file. For only 3 channels its OK, but if I have 100 channels then I want to get rid of these useless data.

After spending a lot of time, I have almost come to believe what I intend to do, it is almost impossible! (hope im wrong)

Thanks in advance

OK guys, its so funny. the answer is so simple. If you use a DAQMX then nothing will be written to the file, but if you use a random number (like me) its will write NaN or 0 in the file.

So funny!

Kind regards

  • . Action file extension

    I can't open a place of trade .Act file extension.  How can I accomplish this?

    Rick

    Go to start / Default programs / associate a file or Protocol with a program and the list for the .Act file extension (I've never heard of it or those who well before - they usually only 3 digits - then be sure that it really is the extension of the file and is not actually part of the name of the file - go to start / Control Panel / folder Options / View and uncheck the box to hide the extensions of file types) known file).  If you find it should list a default program that is used to open these files.  If it is incorrect, click on modify and check if the correct option is displayed.  Otherwise, click Browse and navigate to the executable for the program that is used to open these files (it must be installed on your system for the extension to show high and so that you can open the type of file).  If it is not then no program has installed on the system to add this extension to the list of file types and their associations, which is why it will not open.  You will have to perhaps download and install place of trade (or something to open their files) on your computer in order to open this file (check with commercial technical support room for further assistance).

    I hope this helps.

    Good luck!

  • iMovie export my video in a file?

    I exported a video on iMovie last night and it worked fine.

    I have just cropped down a minute 17 video, 7 minutes now. I click on click action, file, resolution 1080 p and high quality.
    I then click Next and save on documents. I have no record checked theatre. Usually it takes a few minutes to record a video to my files, but now, it doesn't seem to work at all.

    At the top right of the screen where it shows the circle and the progress that saves your video, the circle is left empty.

    When I click it, it says...

    Theater - name of my video

    Name of my video - Theater (best quality)

    The time beside the circle indicates the time for export can be anywhere more than two hours, but will be replacing meaning it can go up to an hour, then back up to 2 hours.

    I think that iMovie is trying to save my video to the theater when I have not check marked and am simply eager to save a file?

    I notice there is no loading bar that is usually available. Is there something I can do?

    First thing to try when iMovie is not behaving properly is to remove preferences. Open iMovie, hold down the command and option keys and select this option to delete the preferences. Is this cut of the film that is the same as that previously shared ok?

  • Firefox won't open the shockwave flash files because there are 2 types?

    Firefox does not open some swf files when I say that this is the cause. However, http://edmullen.net/test/poopboy.swf works fine.

    I looked in my Options-> Applications menu and found this http://i.imgur.com/kPVOHdE.png

    So it has got 2 different types of SWFs to meet him. I can't tell the top affliate background is the same way.

    I tried to uninstall the plugin. This removed the bottom and meant that the poopboy.swf I also linked didn't work in the same way, however, put it back, I was just back to the drawing board.

    I want to add that these particular .swf files that I'm running worked yesterday so file corruption is not the problem, especially since I went and all the redownloaded.

    These two SWF entries are on different MIME types that first one appears to be damaged or at least unusual. and probably the second (application/x-shockwave-flash) should be there.

  • How can I prevent the fact Mozilla a bearing load of all the pages in a several page file at a specific site instead of simply loading the first page?

    The question that follows never used on Mozilla, but now it's the only browser where it happens:

    On the site guess - contact.com, there are a lot of links to pages on file that still go several pages. On all other browsers, you can click on these links on the page and they will be able to open individually, as they should. But on Mozilla, it is impossible to access the information on each page, because the browser will make a 'rolling open', opening at the top of each page of the successive until it reaches the last page of the file - sometimes hundreds of pages later!

    Why the only one still on Mozilla and, more importantly, how can it be stopped?

    Thank you.

  • Firefox keeps asking me to open/download PHP file when she used to be able to display properly.

    I use to be able to view local PHP files normally in Firefox with parts PHP not rendered, HTML elements are. Now he's asking if I want to open or save.

    I tried FF editing options so that it presents a preview in FF, but it does not accept the changes. I cleared my cache and everything. I tried to delete the mimeTypes.rdf file thing, but I can not find the folder, in that it is. I tried deactivating/activating "prompts.tab_modal.enabled" in subject: config then restarting FF.

    All are prohibited.

    Web PHP pages load correctly, this problem only when I am trying to load local PHP files. I don't want to install XAMPP or PHP on my computer just to view the files them that I've never had this problem before.

    In the meantime, I installed Chrome and it loads a local simple PHP file very well while FF asks me to save/download when you open the SAME file. Thanks in advance for any help.
