Why CVI have functions that duplicate the functions of ANSI C file handling (ex: Openfile)?

Why CVI have of file manipulation functions that seem to reproduce the functionality of the ANSI C functions?

Is there an advantage to using the CVI functions?

As the CVI was released (1987), until the ANSI-C standard is released (1989) maybe the question should be the other way around!

In those early days, CVI was supposed to be cross-platform, so it was logical to develop a set of libraries that operate in the same way across the different computers it was targeted at. These days, the focus seems to be primarily under Windows, so this philosophy at the beginning is a bit redundant, especially, as you say, with the widespread adoption of ANSI-C.

Personally, if there are similar functions in CVI, and ANSI, I'll go for the ANSI, whenever for portability of the reasons, but yet I write code in a number of different programming environments.

  • Why I have to click on the green arrow in the location bar instead of pressing ENTER to invite the new Web page to load?

    When you enter a web page (for example, www.aol.com) I would normally hit the ENTER button on my keyboard and opens the Web page of aol.

    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).

  • I looked at my report system and have several that say "the system resumed stand-by", what happens almost every day. My computer worked fine, what is all this history?

    I use Uniblue to clean my mistakes, if he had a year now and didn't have not encountered any problems. But what is all the stuff 'recovery from sleep mode? Thanks for any help.

    I thought that you said in your first post that you have no problem.

    The release of the standby mode is the computer to wake. Normal.

    With EventIDs you need the source it's EventID + Source. There may be hundreds of EventID 302. And as there is no complete list, we also have the text. This is a partial list - http://www.eventid.net/display.asp?eventid=302

    Registry cleaners tend not to do much (if they are safe to use) or try things that the programmer does not understand and are not safe. Problems may not be noticed for long periods.

    If you plug device USB 2 (or 1) USB 3 (or 2), you will get the message to plug it into a faster port. My computer has USB 1 and 2 USB ports.

  • BlackBerry Smartphones SMS MESSAGES ARE NOT SENT, they HAVE DEMONSTRATED THAT in the WAITING for HELP

    My BB Bold 9000 doesn't send text messages.  I had no problem sending texts to the end of last week.  Now in my Outbox SMS all my text messages are displayed with a red box with a small tail to the 12:00 position and another small line to the position of 03:00, on the left side of the text msg.  When I select the message it shows it is "PENDING". Nothing happens when I select send it back.  The display on my phone is now a symbol like: o_o circles are not separated from underscore.  What does this symbol mean.  I don't think it was until I started having trouble with my text message sent.

    First of all, do this: with the BlackBerry device powered on, remove the battery a few seconds and then reinsert the battery to restart.

    the symbol o_o on the home screen indicates that you have a voice message waiting.

  • Why my version 'phone' that fill the new model?

    Why my version 'Phone' complete as a model?  My website voterengagement.org is a redirected domain from godaddy.  It is hosted on BusinessCatalyst.  He fills fine on computers desktop and iPads, but returned to the model I used the opening on a phone.  I use a Macbook to build sites.  Please notify.

    Thank you!

    Hello Civicbridge,

    It seems that your muse site has a model of phone already created that causes this problem. There are 2 solutions you can try.

    1 remove the phone provision and re-upload the site. To delete it go to the Plan view and right-click on the phone and select "remove phone Layout '.

    OR

    2. turn off phone redirect temporarily until you update the configuration of the phone. To turn off the redirect go to file > Site Properties > provision > phone > uncheck "desktop redirection.

    After publishing the site.

    Kind regards

  • I want to make a checkbox control that duplicates the data

    You know these forms online, you click "mark as shipped" and when you do, it copies the data from the shipping info to the billing fields... I want to do... is this a custom script?

    Fields of shipping

    "stname' (name)

    "stadd" (address)

    "stcsz" (city province postal code)

    CheckBox name = "even".

    Fields of billing

    'stname1 '.

    'stadd1 '.

    'stcsz1 '.

    Yes, you will need to use JavaScript. For example, in the event MouseUp the checkbox you can use:

    (function () {}

    If (event.target.value! == 'Off') {}

    getField("stname1").value = getField("stname").valueAsString;

    getField("stadd1").value = getField("stadd").valueAsString;

    getField("stcsz1").value = getField("stcsz").valueAsString;

    }

    })();

    This will copy the values in the field of shipping to the fields of billing, but if there is a change in all areas of maritime transport, the values not automatically updated.

  • Why Firefox check the compatibility of the additional modules every time I open it? Why am I so directed to the home page of Mozilla? Why not answer you that question the last time that I asked it?

    It's embarrassing. IWant to start using a less troublesome browser, but I like Firefox otherwise.

    Have you tried to Reset Firefox preferences to troubleshoot and solve problems and remove the extensions. <>* (extensions.sqlite, extensions.ini, etc) files in the Firefox profile folder as cor - el suggested?

    If you want to try "dynamite", try the steps 7 and 8 of the troubleshoot and diagnose problems of Firefox article: a clean reinstall of Firefox (remove the Firefox.app from the Applications folder and download (with Safari or another browser and install the latest version of Firefox from www.mozilla.com ) and finally create a new Firefox profile .) If a new profile-Firefox fix it, you can transfer your old profile data to the new profile.
