Idiom to initialize one VI?
Idiom to initialize one VI?
I want to have a code that is executed only once on the first call to a sub VI.
My idea is to run a for loop once (N = 1) on the first call and then zero time (N = 0). An example is shown in the attached code snippet.
When I use a loop for with a tunnel of the loop, it is for me an unexpected result. The tunnel of the loop does NOT have its last value. See the attached picture.
My questions are:
(1) is there a better way to do this?
(2) what are the disadvantages with this idiom?
(3) where it is established that a tunnel loop output is reset to a default value when the loop starts to run?
Best regards

Cannot configure the Pop of Hotmail on Mail account under macOS Sierra
Hello.
I'm on a MacBook Air - end of 2014 with macOS Sierra installed.
I decided to perform a new installation of the latest version of Mac OS. As I did this, of course, I've erased completely any configuration, I had: this has the Mail app.
I want to create access to two accounts different Hotmail via Mail App. Apple unfortunately, it's automatically my IMAP accounts - something I really don't like / want - and I want to create POP accounts!
I check online on how to do it (because Yosemite, holding the Option key during the initial installation, no longer works.) I write a bad e-Mail and after trying to access it, I get an error message and automatically mail gives me the possibility to choose between an account IMAP or pop. Also, it requires me to give the outgoing server and receiving code «»
MY QUESTION IS: What are the current codes for Hotmail? Because I searched online and after typing the (I assume) good, Mail tells me that it does not recognize my email address and/or password. (Be aware that during the execution of this, I also write my e-Mail address correctly!).
I really need my accounts connected to Apple Mail, BUT I really need to make sure that it doesn't copy emails and not delete them from the server!
Thanks in advance for any information you can give me.
Ask Microsoft about the configuration necessary to initialize one of their products to access pop.

using LVOOP with several instrument drivers
I created 3 classes SigGen.lvclass, HP8657B.lvclass and HP8648B.lvclass. The second 2 classes inherit from SigGen is simply the address of the instrument and virtual functions. I created a VI that initializes a class according to the configuration in a file. This VI emits a SigGen.lvclass. This seems to work fairly well with dynamic distribution. So, I created another set of classes for power meters. However, in the VI which initializes one of objects and the fate as a base class, I get a constraint point while on the SigGen I get none. I am new to LVOOP so I don't know that I'm doing this correctly. Can someone take a look?
LabVIEW 8.5 Professional
Nothing to worry about. This is because the cast can't until it hits the indicator so you don't have to only one type of power to the output meter. With the SigGens casting goes to the Terminal output of the case structure (which does not show a point constraint).
LabVIEW should probably be more dynamically in the question about if it shows a constraint when dot LVOOP ascending cast objects.

Problems running code on another PC, the executable runs on two computers
We recently uploaded a LV 2010 licence from one workstation to another and tried running a few global code 2010 LV LV and executable made from the code to the "new" code development station
The executable runs without problem. The code will not initialize one of both devices on a MIL-STD-1553 of the SBS NIC is installed in the workstation.
Why the executable work so perfectly while code originating the executable has problems? Seems there must be something to do with the new position and/or SBS card.
Experience with these types of problems during the migration to a new development computer (mine is running Win XP and LV2010) are very much appreciated.
Thank you
My guess would be a device driver missing for the card of the SBS.
Of course, GE did not the memo specifying the product support materials should be easy to access
I guess you have to beg for support from GE.

If this event occurs frequently, it may be useful to follow the guilty program (start with a clean boot programs and initialize one by one until the message begins to reproduce), but for the most part, it's way to Windows 7 is to tell you it has detected a problem and fixes it so I don't think that more action on your part is absolutely necessary.

When I first tried to install CS5.5, it was fine until the complete step. It would not be complete unless I closed Safari and SafariHistory (whatever that is), but to my knowledge, the Safari is not running. He wouldn't let me move forward without leaving the program, so I finally decided to cancel the completion/installation and started during the installation. But the next time I tried to install it, he gave me the message that it could not initialize. I uninstalled CS5.5, but it's always me that is not the message. I don't have another version of the Creative Suite in my computer. What can I do? Help, please.
Sorry to hear that
You can try to install the SafeBoot mode or via another user once account applications:
https://helpx.Adobe.com/x-productkb/global/start-safe-boot-mode-Mac.html
Or try again with the root account: connect to your Mac as a root user and try to install.
Activation and use of the user 'root' on OS X - Apple support
or if you still get the same error, I suggest that it is better to perform the manual complete removal of files Adobe and start over with the resettlement process.

I changed to Firefox because I was pushed to the madness of insignificant and frankly childish animated startup and the home screens. As far as I am concerned (and I know I'm not the only one), so that they can be some developers personal 'wet dream', they are nothing other than a total loss of pixels.
Now, someone decided unilaterally that Firefox must throw it of simple but elegant homescreen Fox/Globe and join the modern idiom of animation pretty, colorful things to attract the attention of God knows who.
Can anyone provide a simple walk-through of how do to remove or hide these garbage for those of us without qualification degree level in the computer... Please?
The best way to get around that is just to create your own home page and do not use the 'default' on: homepage.
See - How to set the home page
That you have already rejected.You can use this UserStyle - https://userstyles.org/styles/104673/about-home-hide-snippets-and-hide-brand-logo - to hide the two sections of the about: home page House that Mozilla sends messages and videos when they feel the "need".
Many of us have disabled the changes made to the top [brandLogo part] of the Start Page of Firefox and off advertising "excerpts" [under the reservoir of research] that Mozilla uses all the time now, so we don't see this "thing".
If you feel adventurous, here's how to 'fix '.
Type of topic: config in the address bar and press ENTER. Accept the message of 'dragons' to see the Advanced preferences screen. Use the search box at the top to enter the below pref.You can assign an empty string to stop your Firefox to retrieve "extracts" and brandLogo changes the browser.aboutHomeSnippets.updateUrl pref. Right-click this pref and select Edit then clear the value as pref in the box that appears, and then click OK. Who will also disable "snippets" that appear under the container of the research on the default home page.
Then you must open the folder of your profile, via help > Troubleshooting Information > profile folder > > folder view button. Then close Firefox.
Your profile file open with Firefox closed (Firefox '3-bar' menu key > exit/Quit), wait two minutes, then remove the storage\moz-safe-about + House folder in the profile folder of Firefox to remove the brandLogo and stored in IndexedDB code snippets to make Firefox use the default brandLogo and a defined default code snippet.Restart Firefox for these changes to take effect.
If you later change your mind about these changes, you can reset the pref browser.aboutHomeSnippets.updateUrl via the context menu and Reset to retrieve the default to start to use the storage\moz-chest-fort-about + House record once again.

Slow to initialize at startup Ethernet
Lately, at the start, my mac connects to the network. It is wired for good than ethernet, but for some reason it takes a long time for the internet initialize; Sometimes the minutes. No problems one after the connection is established and AHT has not revealed internal hardware problems. Below are the specs for my machine. I use a modem arris and an Airport Extreme. Don't know if the problem is in the router and do not know how to test that. The delay seems to increase over time. Advice?
Network Utility.app (included on your Mac) can show you the speed and meter real connection to any network connection error.
If this is not present in
/ Applications/utilities
It is located in:
/ System/Library/CoreServices/Applications
Your connection should be at the expected speed and there should be no more than a handful of initial errors and no reason continues to errors.

Printer ink system failure message all-in-one HP 6180
I can't print because of the error message following on my all-in-one HP 6180 printer screen:
Ink system failure. Refer to the documentation of the printer Oxc18a0201. I followed all the recommendations on documentation of the printer, such as: installation later HP updates, turn off the printer and remove the power cord, remove all the ink cartridges and then putting back in when prompted. Also, I rebooted my computer. None of these recommendations have worked. I need help! Thank you.
Hello Kah524,
I met your questions and we have a solution for this and you can try it, but that would apply only on starting with '0xC18A' and not '0xc19a error codes.
Try the following steps for Photosmart C7280:
A. - Press and hold the "*" key.
B. - Press the "#" and release both buttons.
Display should say "enter special key Combo".
C. - Press and release in sequence the buttons '1', '2' and '3 '.
Display should say "Support" and display the FW rev (something like R0631R)
Press and release the right arrow button until the display shows "Menu of the System Configuration'.
Press and release the OK"" button.
Display should say "hardware failure status. If it isn't there already, arrow above for "Hardware failure status"
Press and release the OK"" button.
Display should say "hardware failure status: clear." Press OK to erase.
Press and release the OK"" button. Message becomes "hardware failure (breakdowns) resolved state. Press Cancel to continue.
Press and release the "CANCEL" button as many times as necessary, so that, either the "Welcome to Photosmart Express" screen appears, or, the 'ink system failure' is displayed. DON'T TRY TO PRINT AT THIS STAGE.
Using the power button, turn the power off and unplug the power cable from the back of the printer output and the wall.
Wait 30 seconds for the power to get discharged and then plug the power cable into the wall outlet first, and then to the back of the printer
Switch on the device. The printer may display message "USE POWER BUTTON CLOSING the PRINTER" followed by "Press OK TO CONTINUE". Press OK.
If the printer has already initialized, then go to the next step. If this isn't the case, the printer will start the "ONE TIME INK initialization PROCESS". Allow this process to do and not to interrupt. Once the initialization is completed, the printer print a Diagnostic page.
To check, features of the printer print a PAGE of TEST car. If SELF TEST prints, then printer is ready for use or installation of the software.
If the error is still there, or reoccurs replace the unit.
-----------------------------------------------------
0XC19a error messages, the printer can be retrieved.
Good luck and if that fixes the problem please click on Bravo...

Satellite L300-29V - failed to initialize for the logon process
Hello
Trying to upgrade my Satellite L300 - 29V Vista Home Premium to the Toshiba provided Win 7 Home premium with the help of the upgrade DVD Toshiba. I tried this many times now with no success. On each attempt, I get the message "* logon process initialization failed - the Interactive logon process initialization has failed. For more details, please see the event log. "*.
At this point, the mouse is active, but none of the keyboard keys control apart from the pointer appears only on the area of the event, enter and esc. Pressure on one of them or by clicking on the OK button or Cancel will be empty of the screen. A minute later, the blue screen of death will be appear and disappear quickly, after that, I have the option load Win 7 or return to Win Vista. Do go back to Vista (which I did several times that I care to remember) is not a problem and the laptop runs without problem later. At any time I am able to view the event log.
I followed the instructions given by the upgrade DVD, IE. removing the drivers and continued on the upgrade to Windows 7. I've updated the mobile site to download drivers/software Toshiba in order to have the machine as much upto date possible - everything to nothing is outside having more drivers to remove using the upgrade DVD.
The only thing I did is to back up my data and recover Vista to factory settings and load on top of Vista in this way.
But before that I'm looking for the Forum of Toshiba for any useful advice - someone else has had this problem or does anyone know a way around this - if so I would appreciate your help.
See you soon
