Tab control only allows two page selections

I am having a hard time understanding why my VI only allows two specific tab clicks every time I run it.
Should I be using shift registers with the "initializing" Tab Controls on the left of the VI before it enters the loop?
No matter what I do, it will allow me to change the tab controlled pane two times and then it will not react to anything.
Once I have reached my maximum alloted, two clicks, then the main Cycle abort button will not react either.
Kind of stumped... Any help would be greatly appreciated.

WOW,
you realize that two of your event structures are running in parallel with the while loop- and they will only execute once? One event- one event execution event. The construct "finishes" done! it won't look for another event.
Take a look at the shipping examples or the P-C QSM (events) template.
Your efforts are not bad, but, show a lack of LabVIEW basics- Dataflow is a different Paradigm- (AND REALLY POWERFUL) but you do need to understand what happens when you use constructs that "break data flow" like locals, globals, and event structures and read the caveats in the LabVIEW help file to get grounded in "best practices"
CAVEAT:
I've probably "broken" most of the "best practices" guidelines- Intentionally! but I wanted specific things from LabVIEW that I knew would happen without race conditions. 99.995% of my code does not violate the "best practice" rules. I write a lot of LabVIEW- It gives me room in that 0.005% to do "interesting" things.

Printer only printing two pages, any application

I have a Samsung ml-4600 laser printer connected via USB to an Ibook. It worked great for years, but now, no matter which application I'm using (TextEdit, Word, Powerpoint, Safari), the printer only prints two pages. Even if I print using the printer as a shared device, it'll only print TWO pages!
I've tried:
- printing ranges instead of just selecting 'all'
- tried different applications
- switched USB ports and cable
- uninstall and reinstalled driver from Samsung
- removed and re-added printer to printer list
- removed the printpref preference files from library/prefs
- repair disk permissions
- update all OS X software
Now, I can print from a different powerbook using a direct cable connection and it'll print no problem, so the problem is limited to this 800 mhz g4 ibook.
This just started happening, any ideas?
thanks
Kevin

Make sure you are using the 1.2.0.224 version of the driver. If you already are, you can try using the gutenprint driver.

If my phone service is disconnected, can I still use the number to iMessage? Under my setting in iMessages it only allows me to select my linked emails and the telephone number is there but grayed out and i can't seletect it !

Under my setting in iMessages it only allows me to select my linked emails and the telephone number is there but grayed out and i can't seletect it ! It wont activate. I just recentely got AT&T. When I had verizon before and my phone got disconnected it allowed me to still iMessage off my number.

If your phone service is disconnected, it's not your number any more.
If you "just got AT&T", how can it be disconnected?

Using Mac OSX Install Disc 1, I am not able to get any further than the Partition tab. It allows me to select my hard drive selection, but will not allow me to make any other selections. Does anyone know their way around this obstacle? Thanks!

Hello, The Hatter, I read about the 'trick' of backing up, erasing, and restoring too, but I figured it would take longer than defragmenting the disk.
But the defragmentation process has just finished! so I'm gonna try to run Boot Camp again soon!
Thanks for your helpfulness, anyway.
And P.S. I didn't clone my system onto the external drive, I just inserted the Mac OS X Install CD, rebooted holding down the "C" key, and installed a fresh Snow Leopard system onto the predetermined partition. I will use that in cases of emergency, when my main/internal system becomes unusable.

Try ejecting your iphone from iTunes and then close iTunes. Now retry. Hope this helps.

I want to set up Firefox to only allow certain pages to load - how do I do this?

My children are having my old laptop and I dont want them to be able to 'stumble' across anything unsuitable.
How can I set up Firefox so that it only allows pages to load from websites I choose?
Thanx!

Tab control shows wrong display for selected tab

My computer crashed when I tried to post this earlier, so I apologize if the first post actually shows up.
I have seen this for years so it is nothing new, but I don't remember seeing it in any release notes (sorry if I missed it).
Upon loading the .vi (or as an executable), the .vi shows the wrong page for the selected tab. After selecting a different tab, the control works fine. Also, if you create a property node to read the tab value, it matches the displayed page....just the selected tab seems to be incorrect.
A work around is to select the default tab before saving the .vi, but why is this happening in the first place?

Hi Stephen,
The erroneous tab display is something I see on most of not all of my code that uses a tab control (each is a typedef).
What change would I make the the typedef? If I disconnect the tab from the typedef then I will loose the advantages of using the typederf...I will stick with the workaround like I have for the past 3+ years.
Isn't this a LabVIEW bug since the displayed tab is not equal to the value read from the control? I have not tried it on this example I posted but in the past, writing to the control does not fix the displayed tab (writing the control may not work since I wrote the same value that LabVIEW thinks is the current value, but the displayed!=actual).
Thanks,
Todd

Four pages of apps in iTunes, but only first two pages visible on iPhone!

If I connect my iPhone 4 to my notebook and launch iTunes, I can see four pages of apps on my phone - two pages, then a blank page, then a further two pages.
However, looking at the phone itself, only the first two pages are visible (and only two little dots at the bottom of the home page).
I can shuffle the apps around in iTunes without any difficulty, but when I press 'apply' the sync ends with everything back as it was in the first place.
iOS and iTunes both up-to-date, rebooting and soft reset doesn't fix.
Hope someone can help!
Thanks

We are having the same problem. Any updates?

I have 9 tabs, but when I try to make a tab group, only the current page shows up as a thumbnail, not all the tabs. I can't get them to work for me. All the tabs are listed on the right side of the tab groups box. What am I doing wrong?

There's no thumbnails to drag around except one on the left side of the page (the one that's open). The right side of the page lists every tab I have created.

Perhaps your problem is that '''you must save your browsing history''' in order to use app-tabs that would apply to groups as well but I did not test.

I would suggest that if you do not save that stuff in bookmarks, that you will probably have a serious problem soon and lose your tabs, so if you count on them you could lose them. They should stand up to repeated restarts but I would not count of them as app-tabs myself, for one thing it is new, the other is I have to frequently wipe them out and restart, because I actively open new content into them and go back to the beginning of the tab history, and sometimes I can't, and sometimes I lose them by accidentally closing them -- and I must be able to close them in all manners that I close other tabs or I wouldn't be using them.
There are people who keep 200 tabs open through restarting, that is not for me, I try to clear out the tabs frequently.
That is what app-tabs are for as opposed to home pages, but I did have a problem when I tested with 120 since as app-tabs only about 65 can be seen at once even though I did reduce the width of app-tabs to about 2/3 the size that they were.. Problem I had when I restarted was that the window enlarged a bit beyond the screen, and my tab counter disappeared until I reduced the count to about 65. I do not allow tabs to scroll so you probably wouldn't have that problem.
I forgot to test home page with 60 tabs. I do have something set to 75 though have to check that. I tested with 60 pages as home page. Brought firefox down and backup with the 1 app-tab and 60 home pages the app-tab is the same size as the 60 normal tabs from home page.
Never used group-tabs by choice, since they messed me up I stay clear of them, I don't like them or anything large panoramic type of large thumbnails.

I have three airports connected to my computer but when i ask for multiple speakes on the streaming section it only allows two of them at a time.. is there a way to have all airports streaming at the same time to different speakers.

Lost all my thumbnails - new tabs open only a blank page. How do I get them back?

The support topic on this question says to look for a "pin" icon in the upper left corner of the browser. I do not show one. Firefox used to just automatically populate my new tabs page with the thumbnails, but it is no longer doing that, and I don't know how to fix it.
I downloaded some freeware that changed a number of browsing options (default browser, added Bing bar without my full knowledge, etc.). Got that all removed but then Firefox wasn't working well, so I had to uninstall/reinstall the program. Now my thumbnails are gone and I can neither get them back nor create new ones.
Help!
Cheers, Dolly

MOST EXCELLENT. Not only did this work, but I was able to do it all very easily AND it brought back all my previously set up thumbnails in the order I had them arranged on the new tab pages! Wonderful.
I will definitely keep these instructions for future reference, but I had already gone in and deleted all apps and extensions that I did not recognize as from Firefox or that I hadn't added myself. So I'm pretty sure I got rid of the pesky malware that caused the problem already. Great links for that task however.
Thank you SO much!!
Cheers, Dolly

Blurb Books ONLY ALLOW 240 Pages. Please Help

I use the Blurb software to create Yearbooks, but ALL of our Yearbooks that we create in Blurb are over 240 Pages. We sell Hundreds of yearbooks created by Blurb every Year and this year it will be over in the 1,000's of Yearbooks. I would LOVE to use the LR features to create the Yearbooks, but I need more than 240 Pages. We normally average about 320 pages per book, with well over 1,500 images. How can we do this in LR4?

You are correct, that is a Blurb limitation for all papers except for the Lustre. So I now see what the issue is. Adobe should allow the STANDARD Paper as an Option for Printing. I only use the Standard for large yearbooks and Standard Paper has up to 440 pages. I know on the LR Beta Adobe Video it was stated that Adobe customers would not want the Standard Paper, but that is not correct. Blurb is one of the few companies that allow such high page counts and this is with the Standard Paper.
This is a HUGE issue for us, as we had over $30,000 in Yearbook orders between this year and last year. And I would love to intergrate to creating the yearbook with LR4.

HT202213 I have only allowed two playlists to be home shared but my whole library is being shared? Help?

I am setting up Home Sharing on my kids computers and on my computer have selected to only share their playlists. However on one of my kids computers it is showing the entire library.
Can anyone help?

The way home sharing works is your entire library is shared. You can consider Windows sharing options If you put music in your public folder on Windows, your kids will access those files and be able to drag those over and import in itunes.

Scrolling only allows one page spread to be visible?

Hi,
I have run into this on other files, but for the life of me can't figure out how to go back to the original setting of being able to scroll through all the spreeads using the wheel or the scroll bar and seeing the next spread -- currently when I attempt to scroll there is nothing visible below the the current page -- but if I use the alt+pgdwn or pgup that will take me to the next spread.
Any ideas?
Thanks!
Carol

Scrolling has been pretty reliable in CS4. Could be bad prefs, or a bad video driver. to repalce your prefs, I'd use the manual method here: Replace Your Preferences
To test the video driver, trun off vido hardware acceleration in the display properties.

How to hide controls/indicators for different user selection?

I am trying to simulate time interval analyzer using labview tools but I have a problem in making identical screen as it is on HP 5371A. The only problem is when you choose different arming mode, text pops up on the bottom with different parameters for every mode. So I am trying to build my front panel so that I will have identical features as on HP screen but how can I make some controls/variables (such as delay in secs) dissappear from F.P. for particular arming modes and then again appear for other cases (modes). Thanks in advance for help

What you'll need to do is to use a while loop to monitor the state of the control. Based on that, you can make other controls visible or invisible, change the strings of a single control, or make controls enabled or disabled. I've attached a simple VI that shows how to make multiple controls visible and invisible. I've only done a few of the arming mode options. For a complete solution, you're going to have a lot of property nodes and I would look at using control references inside of a sbVI. Another way to do it is to forget about emulating the instrument's panel altogether and use the versatility of a computer screen. You've got a lot more real estate than most instruments and have things like tab controls that a user can select.
