custom RefNum - what is underlying numeric type of refnums and how to respect the subtype

Specific RefNum, I intend to help is based on the byte stream file refnum - and will have an impact in and out of a DLL through knots of interface code - would it be U32 or I32 underlying type or something else?

I based the concept of subtype on the following online reference:

http://labviewwiki.org/RefNum

Is to correct the above and the way in which the 8-bit values are encoded in the type digital refnum (ESM or other?)

The subtype is not at stake here, nor do anything in the external code to change. The refnum itself is a MagicCookie (definition extcode.h) and an opaque value that, together with the type of refnum, which is implicit, determines resource for LabVIEW.

Include extcode.h in your /cintools directory , declare it as MagicCookie or LVRefNum, which is an alias for a MagicCookie. There is no C interface function to work directly with a LVRefNum for a datalog file, or a bytestream file, but for the bytestream file you can use the FRefNumToFD() function to get the underlying file descriptor and then use FM * () functions that use a data type of file to read and write to this file.

  • What does this mean and how to fix: the router address you entered is not compatible with your WAN IP address.

    I connect to an access provider via Airport Extreme, which is extended through two Airport Express.  When I try to edit anything in one of these devices, even a name, I get this message: "you have entered the address of the router is not compatible with your WAN IP address.  My connection seems to work, but there is clearly something wrong with her.  The Express has no DNS and will not update without the same message.  I have no idea what this is all about and will greatly appreciate the ideas.

    This means that WAN Setup does not or does not install across the network.

    The best way to solve this problem is beginning on...

    Reset all three at the factory and reconfigure each in turn. Do the extreme first and make sure it works... Then add the express.

    If you need help with that we will need to know which modem or modem router to your ISP gave you and possibly the type of services to wide band... and who is the provider.

    Give us screenshots of each installer as you do.

  • BlackBerry Smartphones do you know what are my problems with my camera and how to solve?

    Mine is Curve 3 G running OS 6. I have 3 years now.

    Never installed any themes. I removed all languages, except for English and mandarin. Obtained third-party applications, which are whatsapp and screen grabber. I also youtube, twitter and yahoo messenger but I think that they are developed by rim. I uninstalled the default games from the early days, owner of the device and never install others. I also removed the maps and the world of blackberry. In any case, they are useless.

    I don't store a lot of pictures and the ones I did on my ram external 2gigs. I have not all media files. Just the default values.

    I join 1 group and it's not active. I don't have multiple conversations. I end conversations as soon as they are finished. BBM contacts grow about 1-2 monthly and phone books from 3 to 5 every week. I am a seller.

    I delete e-mails from the unit as soon as I finished reading the. Never navigation because the browser kills each front page loaded completely, making me unable to use youtube.

    I remember regular cleaning to run hourly.

    I do battery pull everyday because I'm tired of waiting for the clock or the gel to disappear, which could take more than half an hour if I let them which of course eventually crashing.

    Never have data backup because the device freezes the second I connect it to the PC with desktop blackberry on.

    So the question is do you know what are my problems and how to solve? Because I did not.

    Hello

    Well... We must memory cleaner is enabled, this feature is known to cause many problems!

    Try a battery pull reboot and let us know.

    I have a simple test form that contains a cftree and some fields of seizure/hidden. Whenever a tree node is selected, I want to change the values of the fields of entry/hidden to some node is selected. Pretty simple, but I can not understand how to change the values of the hidden fields.

    Load the form, select "ItemA" and click on submit. Do not change the values of the hidden form fields. They are always "not defined". What is the correct syntax to change the value of the hidden field?


    The correct syntax is

    My system is Vista.  Game camera is a Bushnell HD and I can download from an SD card or a direct cable to the photo gallery.  However when I play the video all that can be seen is the same type of screen saver of colors and of protections in motion seen when playing music.  The sound of the segment can be heard clearly, but you don't see nothing recorded.

  • PCoIP and how to increase the capacity of a sweet view customer image decoder

    We see a huge difference in this capacity between a zero client and sweet and I was wondering if anyone knew if it is possible to change this functionality on the soft client?  We find that the zero clients have 10 x vs the soft client capacity.  Basically, in a network scenario EXTENDED, we see that zero clients perform slightly better than the soft client and made the difference in ability of the decoder picture wondering.  The soft client is a ThinOS (Stratodesk) running on an I5 gen 4 processors and 2 GB of ram.

  • What is GUI and how to get the latest edition of the FLASH to download

    I said trying to download the latest edition of the FLASH and an error message came and said that he couldn't download a GUI

    GUI stands for graphical user Interface.

    I appreciate that you try to download and install Adobe Flash Player on this site: http://get.adobe.com/flashplayer/ or maybe some other website? What exactly was the message?

    What browser do you use? Adobe Flash Player can be installed only to the 32-bit version of the web browser. If you have Windows 7 x 64 it is very possible that you have started IE x 64 and you can't install Adobe Flash Player. You can find IE 32bits version by typing in the search box of the start 'Internet Explorer' menu and launching the appropriate version (not x 64).

    ...

    You can try to uninstall Adobe Flash Player using the uninstaller of this site: http://kb2.adobe.com/cps/141/tn_14157.html and then install if from scratch.

    ...

    You can also install another browser such as Firefox , Opera or Google Chrome and see does the problem also occurs in their case.

  • Windows XP - what is this BSOD code meaning? And how to solve?

    BAD_POOL_CALLER * STOP: 0X000000C2 (0X00000CD4, 0X8175A2E8, 0 X 0000007, 0XB8A6B448)

    The details of the error checking (double free) suggest memory corruption occurs.  This may be due to a hardware failure (defective RAM, for example), or a bad/buggy driver or a driver that is not designed for the version of Windows you are using. Consider using driver verifier as described below, to determine which driver is corrupting the memory.

    General to deal with the bluescreens indications:

    Consider running chkdsk on all partitions.  Leave complete chkdsk on each partition and see if that helps.

    It may be useful to use the driver verifier.  To activate the... Driver Verifier start-> verifier.exe-> OK-> create standard settings-> next-> driver select the names to a list-> next-> sort by provider-> select all other Microsoft drivers-> finish and OK your way out of the dialog box.

    Then restart and use the system as you normally and wait for a problem.  In case the system does not completely start after activation of the Verifier, boot mode safe and run driver verifier and tell him to remove the changes.

    Wait for an error checking to happen after you have enabled the auditor as described and then download the dump on your SkyDriveand provide a link.

    Also consider running SFC/scannow.

    If you start in safe mode, do you still feel bugs? What if you do a clean boot, or boot device?

    Consider the memory with memtest86 or Windows Memory Diagnostic test. Note that memory that pass the tests isn't necessarily good memory - he not only failed a review.  Examine systematically to eliminate the system RAM - run with a few modules for awhile and see how things are going. Then try the other modules.

    Other common suggestions include ensuring drivers are up to date, but also to ensure that you use the latest version of the BIOS.
