Writng a dll in microsoft visual c++ and import it into labview

everytime we create a dd project there will always be this prompt which will ask us whether to build an empty dll project or a simple project or complex one.Under what circumstances will i use a simple one and under what will i use the more complex one.Is the two prototype that is provided by microsoft enviroment be sufficient on most apllication? will there be a case where we will have to build our dll main?

The best place to find information regarding dlls is from the technology creators themselves. Go to the following link to view the definitive overview on dlls at the Microsoft Developer Network (MSDN):

  • Writing dll in visual c++ and importing it to labview

    I am writing a Dll using microsoft visual c++. Under the source file i wish to include this header file(#include "extcode.h")sothat i can use the labview library function in c++.However when i try to duild the dll,it will produce a linker problem which say that unable to find this file or no such file exist.
    Another point that i am not clear of is,under microsoft visual c++,can i either choose to add this file by listing it in mysource code(#include extcode.h) or can i just simply add by clicking on the project tab->add file ->indicate the file name?
    when writing a dll, i can either choose to write in "C" or winapi.Which of these method will provide a better soln.
    in lbview when we declar
    ed the type of data say integer, i understand that there is only short integer(16bits) and a long integer(32bits) and achar (8bit integer). However in a c program there is short int,int and a long int so how i am able to declare an int as regard to labview?

    Derek,
    Use the following link :

    I think you will find all you need there. The first link off this page will also give you a table of how labview ints convert to other development enviroment types. There are also links for creating a DLL in C++ and using it in labview like you are trying to do.

  • Export scenarios from XI and import them into PI

    Dear experts
    We are planning to upgrade our exitsting XI 3.0 to PI7.0.
    Due to system requeriments, we need to install PI on new hardware and migrate all the existing scenario's from XI 3.0 PI7.'0
    How to migrate the existing ABAP developements from XI to PI  ?
    It's possible to export scenarios from XI and import them into PI?
    Thanks, in advance
    Carme

    Hi,
    you should go to PI 7.1 and not PI 7.0 otherwise it makes not so much sense.
    And yes it's possible to migrate your scenarios. If you have UDFs you have to check them because the java version has changed.

  • Any value in exporting iPhoto pictures and importing them into Aperture?

    I am moving from iPhoto into Aperture (moving my library again actually) and I know that iPhoto and Aperture can share the iPhoto library once it has been updated but I am wondering if there is any value (or even if it is possible) to export all of the iPhoto pictures and import them into a new Aperture library?  The reason that I'm asking this is that I know there are a lot of duplicates in my iPhoto library and I know that Aperture keeps only the original.  A couple of weeks ago I moved my iPhoto library onto an external LaCie SSD disk to use with my MacBook Pro but unfortunately corrupted that library and have to make the move again.  If there is any value in changing how I'm managing my library I should do it now.
    The library corruption was caused by me needing to leave for work and disconnecting the LaCie before Aperture was done sync'ing with my Flickr account.  When I tried to use Aperture the next day it was not able to repair/rebuild or use the iPhoto library at all.  I was unfortunately not backing up the external disk so I lost everything that I had done to clean up the library after the move.  One lesson that I learned was do not automatically sync with Flickr because doing this on an MBP via wireless with an external disk library can add a lot of delay to shutting down Aperture after an MBP wakeup.

    Just in case you have not come across these:
    Aperture 3.3: Using a unified photo library with iPhoto and Aperture
    Aperture 3.3: How to use Aperture to merge iPhoto libraries
    but I am wondering if there is any value (or even if it is possible) to export all of the iPhoto pictures and import them into a new Aperture library?
    You can - an it will depend on what you want to achieve, if that will usefull. The way to do this would be by imprting your iPhoto library into an Aperture library using Aperture. But Aperture libraries and iPhoto libraries are now interchangable - both are photo libraries, and you could simply use your iPhoto library in Aperture and be done now.
    Some reasons why you would want to turn your iPhoto library into a library recognized as Aperture library by importing it into a new, empty Aperture Library:
    As long as the photo library will have the "Kind: iPhoto library", you will have to upgrade both iPhoto and Aperture always to the newest versions, or you will not be able to upgrade to a new library format, when a new release of Aperture comes - say (iPhoto '12 and Aperture 4); you will probably have to buy both new releases to continue working with your iPhoto Library in Aperture.
    If the kind of your library is "Kind: iPhoto library", it will appear in the Media Browser in the iPhoto section, not in the Aperture section, even if you are using it as your Aperture library. And before syncing with iTunes you will always have to open the Aperture library in iPhoto to point iTunes to it.
    Also, in Aperture you have more control about what will be included in your library - In iPhoto there is no way to specify the size and quality of previews. If you do not want or need previews, or you want smaller previews, or no Faces, it would make sense to recreate your iPhoto library by importing it into a new, empty Aperture Library.
    If you have more than one iPhoto Library, you can merge them into one big Aperture library to be able to browse all your images without having to switch between libraries. Aperture works very well with really big libraries. There is no need to split libraries.
    The reason that I'm asking this is that I know there are a lot of duplicates in my iPhoto library and I know that Aperture keeps only the original.
    That is what I meant by having more control on what will be stored. iPhoto will always store a very high quality preview of your edited version; in Aperture you can decide what the preview size and quality will be. But Previews and originals are not duplicates; they are not the same image.

    If you're trying to import it into FCE, it needs to be DV/(HDV), not AVI or MPEG4. Try using MPEG Streamclip + the QT MPEG2 Playback Component. Handbrake isn't going to get you where you need to go.

  • PSE12 Organizer - can you copy photo from one folder to another and import copy into Organizer and still have original in other folder

    I have been using folders to organize all my pictures and I will copy photos from folder to folder, often having them in 2 or 3 folders based on use.  I tried to copy a photo in Organizer PSE12 from one folder to another and you can only move it, that means I can only have one copy of the photo.  That is fine if I am using tags and want to search for it, but I want to have mult copies in mult folders. Organizer will recognize that it is there but it won't import it into the new folder. Until I move it, it stays in the original folder.  I can drag it out of Organizer and drop (copy) it into a new folder fine, but it won't show in organizer in the new folder.  Is there any way to copy and have multiple copies show up in multiple folders?

    Hi,
    The organizer works on the principle of not having multiple copies of the same photo.
    If you have multiple copies spread in different folders, then making changes to one doesn't affect the others. The use of tags and albums are there to give different views of your photos.
    You can't have multiple copies with exactly the same name even if they are in different folders. You could select a photo and duplicate it (File -> Duplicate) and then move the copy into a different folder but the name will be different.
    If you want different folders for a specific reason, it is possible to use albums to collect the group of photos and then export them to a new folder outside of the organizer. You can also rename on export which is useful if you want to arrange the photos in a specific order.
    Hope that helps a bit.

  • I purchased CDs and imported them into my iTunes and when the artists has other artists featured on the tracks it separates these tracks into a different album. How can I consolidate these back into one album?

    I have CDs that I've purchased from music stores (ie. Best Buy) and have imported them into my itunes library. The problem is that iTunes has separated all the tracks that feature another artist into a separate album. I want all the songs filed under the same album, so that when I play the whole album, I can hear all the songs. Also when the album work is not showing up on some of these CDs. How can I fix this?

    The sort fields should generally be empty unless you've putting in custom values to sort solo artists by their surnames. You can apply common changes to thousands of tracks at once, just don't apply the wrong change because there is no undo.
    It is a good idea to backup before undertaking large scale changes. See this backup tip for a suggested approach.

  • Cut parts from song and import them into the sampler on ipad

    How do I cut parts of my song in garageband (ipad) and put them into the sampler to fix the pitch on specific parts of my pre-recorded vocals?
    For example, I already have a song I recorded, and I would like to simply cut a few seconds of the vocals, go into the sampler, fix the pitch, and then re-insert the editied piece back into my song.
    Is this possible on the ipad? I know that the "autotune" option isn't available on the ipad, but I simply want to fix the pitch on a few notes and I was wondering if there's any way to do that.
    If there's not, do you have any suggestions or any app reccomendations that might help me achieve this? I can't afford a macbook pro so that's out of the question.
    Sorry if my explination isn't clear! And thanks for any help :]
