Possible bug with Tab Control and Context Help?

I created Description and Tip text for each Tab of a tab control I am using on my front panel. I have a subVI that is called by selecting a menu item from my main front panel. The subVI's front panel also has a menu system and a Tab Control. I have Description and Tip text written for each of the tabs on the subVI's front panel.
When I enable context help from the menu of my main VI, the proper help text shows up for the tabs on the main vi and, when I bring up the subVI's front panel, for its tabs as well.
So far so good...
Now I builld the application and run it as an executable. For ALL of my panel tab descriptions, I get the tab's label in bold text, but no description (just a blank area).
Is this a bug in LabVIEW?

I'm still seeing this behavior in LV8.2.1. Does anyone know if/when it was fixed? Also, my tip strips show up in the corner of the monitor when I mouse over a tab (in both the executable and the development version).
I see it still even in 8.5.
The Help part of the bug is still NOT fixeed by NI.
But I dont get the tool tip appearing in the corner of the monitor, it is showing up as usual.

Possible bug with Pick flag and Collections

Odd behaviours in v3.3 (Windows) with pick flags in Collections:
Create (or use) a Collection Set which contains a number of different collections
Assign Pick plag to one photo in each collection
Bug 1: Highlight Collection Set and note that none of the images shows the Pick Flag in the thumbnail view. Also Filtering this view with Pick flag fails to pick up the Flagged images
Now return to one of the Collections within the Set and create a Virtual Copy of one of the images that has a Pick flag. (Note virtual copy does not have a flag - which seems logical). Return to Collection Set and (Bug 2) note that Pick flag has disappeared from original image and now appears on Virtual copy.
Something wrong here somewhere I suspect.

I could partially repeat bug 2.
I have Collection Set (Test) which contain to collections: "Collection 1" and "Collection 2". Both Collections contain 4 images.
I selected "Collection 1" and applied Pick flag to all those images. When I select Test (Collection Set) I got 8 images shown, which none had flags. Ok, this works as expected. I selected "Collection 1" and then selected 1 image and made Virtual copy from it. Lr show me now 4 images with Flag and 1 virtual copy without. Again, works as expected. I now select Test (Collection Set) and I get 9 images (as expected), but one of them, the virtual copy, has pick flag applied. Not as expected. If I go back to "Collection 1" I get four images with Pick flags and one virtual copy without. (as expected.)

Possible bug with HTML emails and attachments from Mail.app

I'm trying to send an attachment with an HTML email from Mail.app and getting unexpected results. I've been messing around with the order that things get added to the new e-mail and it seems that I can have either an attachment or I can have HTML email, not both.
The code... (of course simplified)
tell application "Mail"
set new_message to make new outgoing message with properties {subject:"A subject", sender:"[email protected]"}
tell new_message
set visible to true
make new to recipient at end of to recipients with properties {address:"[email protected]"}
tell content to make new attachment with properties {file name:alias "Path to your file as string"} at after the last paragraph
set html content to "<head><body>Some HTML here...</body></head>"
end tell
send new_message
end tell

The problem is that there is no such thing as HTML email.
Well, I wonder what I have been generating for over three years now. RTF ? Because it sure looks like HTML. I must agree that HTML is not documented or even mentionned in the Mail AS dictionnary, but it does work, though you must specify visible to false so that it does. Here's my sub:
tell application "Mail"
set DMF to default message format
set default message format to plain text
set newMessage to make new outgoing message with properties {subject:theSubject}
tell newMessage
set visible to false
set sender to theSender

set html content to "<html><head><title>" & theSubject & "</title></head><body>" & "This is an automated response." & theSource & "Find your personnal planning on the web: " & thelink & "
</body></html>"
end tell
send newMessage

"Tab" control and Tab order of controls inside the tab

Hello everybody,
I have created the tab control with 6 'tabs', inside every tab I have some controls, like edit fields etc. I wanted to make an order of controls for every tab, so I have selected the option "Tab-order settings" from menu "Edit" (sorry for translation, I use non-English version of LabView), and tried to set the order. After saving it with "OK" button it turned out that the order is not changed. Simple it seems that the option doesn't work for controls in tabs. Is this a bug or do you have a solution for this?
TIA,
Yazilim.

Sorry LabviewGuru, but I haven't found anything concerning Tab control and tab order inside it. Of course, I have found the topic "tabbing through front panel objects", but it simply describes how to change order for standard controls, not for controls which are inside the Tab control. But maybe you have another, extended help? So can you please copy and paste to discussion forum message this part of your help which concerns the Tab control and tab order, and then send the message?
TIA,
Yazilim.

Bug in Tab Control when inserted into SubPanel

Just would like to report about pretty old bug, which is still present in latest LabVIEW 2013 SP1 13.0.1f1.
I would like to insert SubVI with Tab Control into SubPanel, something like this:
When SubVI executed, then I will set it to Page 2:
Now what I've got in my SubPanel:
Page 2 is active, but selector is not actualized - still show me active Page 1. Fully inconsistent.
Not sure if it was reported already or not, but needs to be fixed from my point of view.

But yet another problem with tab controls...
Seriously though, if you are already using a subpanel why complicate matters with a tab control?
Dynamically swap VIs in and out of the subpanels to present the same user experience as there was with the tabs.
You're right - there are many ways to workaround about this bug. For example, if I will use Property Node instead of terminal or local variable, then it will working properly.
This contstruction with tab control in subpanel used in my settings dialog. I have modular plugin architecture, and some plugins may have settings, so they organised in the same way as LabVIEW Options dialog - listbox with installed plugins and subpanel, where according subvi from plugin is inserted. Mostly all plugins fit into my dialog (which is not resizible at this moment), but some modules have lot of settings - then they splitted into groups and the tab control is used (NI does this with vertical scrollbar, which is also not perfect).
When user made changes in settings, then last opened page is saved - when this dialog opened next time, then user should see last page - this is why I need to set page programmatically.
Really, I don't like to change whole architecture for workarounding bug in LabVIEW just for few modules. At this moment I using property node and it works for me.

Bug? Tab control breaks graph autoscale (+workaround)

I had this really annoying problem where two of my graphs did autoscale and the other two didn't... Although all the code and graph properties were exactly the same.
I finally figured it out... The graphs are in a tab control. And only the graphs that are on top get autoscaling. Labview 'forgets' to autoscale the other graphs when you show those other tabs. Even when I use a property node, I can't force the graphs to autoscale, unless they are on the showing tab.
Feels like a bug to me.... I can understand that graphs aren't updated/autoscaled when they're not shown for performance reasons... but I think the axis should then be updated/autoscaled as soon as the corresponding tab is shown. And it certainly would be nice if the axis does autoscale when I explicitely ask for it using the property node...
Now that I understood the problem, I could also make a work-around. I made a 'value changed' event for the tab control, and put the property node autoscale code in it. That way, I ask for an autoscale right after showing the new tab page. (See attached vi for example of the problem and work-around.)
The workaround works fine... but I think that this should be default built-in behaviour for graphs in tabs that have the autoscale enabled.

Hi Anthony,
This is a known issue that was partially fixed in LabVIEW 8, which you appear to be using. By partially, I mean that the behavior only persists when you update the value of your graph using a property node (either Value or Value Signaling). If you update the value using a direct wire connection to the graph terminal, or using a local variable, then the problem goes away. I would recommend using either of these methods, because they will fix your issue. Also, in general a direct wire connection or a local variable will greatly improve LabVIEW's efficiency in terms of updating the front panel. The only situation where this fails is if you need to update your graphs from inside a subVI using control references.
Because that last note is a very real situation, we will notify R&D of this matter so that they can investigate this further. Thanks for bringing this to our attention.

Can someone confirm a possible bug with Universal Access?

Can someone confirm a possible bug with Universal Access?
I have a Mac Pro 3,1, 10.7.1 but if you could confirm or not this possible bug with any model.
In Energy Saver preference pane:
Set Mac to never sleep.
Set Display Sleep to ~2 minutes.
In Desktop & Screen Saver:
Set screen saver to start at ~1 minutes.
In Universal Access:
Check Enable access for assistive devices.
Check radio button Zoom to On.
Zoom in window not checked.
Confirm that Zoom works by pressing:
⌥⌘= (option, command, =).
Set screen back to normal by pressing ⌥⌘-.
Let screen sleep after screen saver starts.
Wake screen and see if ⌥⌘= still works.
Thanks … Ken

Other than the time intervals (smallest Screen Saver kick-in is 3 minutes), it works fine for me - at least I can still zoom in/out after waking the display.
Tested on two different MacBook Pro models in 10.7.1

Dynamic event registration wont work with Tab control

In LTR volume 11 No1 we find the "Dynamic Event Handling.vi".
I had placed the controls on a Tab control and now this example wont work.
Is there a solution to this problem?
Scientia est potentia!
Attachments:
Dynamic_Event_Registration.vi ‏51 KB
Dynamic_Event_Registration(controls_on_Tab).vi ‏64 KB

Yes. The first stage of the code registers mouse down events for all the controls. When you added a tab control that meant that a mouse down event was registered for the tab as well. So now when you click on an object on the tab LabVIEW must decide whether to fire the mouse down on the tab-event, or the mouse down on the object on the tab event...It goes for the first but since there is no description for the tab no dialog will be displayed. If you add a description for the tab you'll see that it fires the event with the tab and you get a dialog with the tab description.
So - how to fix. Well, it's not that simple, one might think that to exclude the reference to the tab when you register the events would do the trick, but it rather seems that LV will always t
hink mouse clicks are on the tab and not on the objects on the tab.
The solution though is to get the references to the objects by reading the controls on page property of the tab control. So instead of reading the controls array from the front panel read the pages references of the tab and then the controls on page array from that and then register mouse down events on that array.

Tab control and content

on my main page i have a five tab control, and each tab has its own content. below the tab control and external to it is another region containing a dynamic page portlet. this region faithfully shows its contents when 4 of the 5 tabs are displayed. when the 5th tab is displayed, it is empty. i've cleared the cache numerous time with no effect.
if anybody has any ideas please pass them on.
thanks,

Whats a good mac to use for a home flight simulator with flight controls and foot pedals?

whats a good mac to use for a home flight simulator with flight controls and foot pedals?
My old 6100 AV worked great on A10 ATTACK, back in 1993.
whats a good set up now a days?
I havent seen any MAC set ups as a lot of the after market accessories are on Windows platform.
Is there a way or should I get a dedicated simulator on PC?

The fact that USB flight input devices appear to Windows only is not a limitation; for Mac most are programmed through the sim itself. I know X-Plane does that.
I've simmed a lot and know that good sims need a lot of processor and video hardware horsepower, and you'll also need a lot of RAM. They also run up the internal temps. A Mac Pro has better cooling than an iMac. You can get a program like SMCFanControl to manually set up the fans speeds before starting the sim.
I know of no sims today that will still run on a PowerPC Mac (2005 and earlier) so you need to look to an Intel Mac with top specs. If looking at iMacs, start by looking for the quad-core i7 processor. Those models usually came with an up-rated video card. Thing 12 to 16GB RAM.
My 2010 iMac has the 2.93gHz i7 processor, video hardware (ATI 5750) with 1TB VRAM, and 12 GB of RAM. It runs the x-Plane 10 demo fine but I've not bought the full version because v10 seems to make foot pedals darned near mandatory, and I don't want $100 worth of pedals under my regular work desk at the moment.

TS3474 I purchaed the earpods with mic & controls and they don't work with 6th generation nano. Are the features supposed to be compatible with this model of nano?

I purchased the earpods with mic & controls and the features don't work with 6th generation nano--is this normal?

Hi there,
According to the product page:
The remote and mic are supported by all models of iPod, iPhone, and iPad (not all models support volume up/down functions). Audio is supported by all iPod models.
Your iPod Nano may be one of the models that does not support the volume up/down function. Take a look at the page below for more information.

Possible Bug with Drag-and-Drop Being Published via HTML5 - Getting "Undefined" Error When Dragging Object

Hello,
I came up with a way to use drag-and-drop interactions that will take advantage of file input so that I may create a drag-and-drop interaction that uses one draggable object over and over allowing multiple scoring/tracking possibilities. Example use...is having the draggable object be dynamic in that it randomly changes its text so that a learner can drag a term it's possible classification.........thus allowing the possibility of having many terms easily loaded without having to redo a drag-and-drop interaction for each needed terms/classifications updates/changes.
My Issue: When using a variable to represent the text for a draggable Smart Shape object, I'm getting the error message "undefined" when, clicking/pressing on the object, as well as during the drag of the object. This issue occurs when publishing the project in an HTML5 format. Flash interestingly enough seems to work perfect...but we are not interested in publishing via Flash any longer.
To better help you explore this error message, I've set up a test project so that you can see when and how the "undefined" message shows up during a drag-and-drop interaction. I've also included the Captivate 8 project file used to make the exploration project I'm sharing in this post.
Link to Captivate project I created for you all to explore "undefined" error message": http://iti.cscc.edu/drag_and_drop_bug/
Link to this Captivate 8 Project file: http://iti.cscc.edu/drag_and_drop_bug.cptx
It's pretty interesting how things react in this demo, please try the following actions to see some interesting happenings:
Drag the Yellow (or variable drag box) to the drag target.
Drag Black Hello square to Drag target and click undo or reset - watch the undefined message come up on the Yellow (or variable drag box).
Drag the Yellow (or variable drag box) to the drag target and then use the undo or reset.
Move both draggable boxes to the drag target and use the undo and reset buttons...
Anyhow, I know you all are sharp and will run the demo through its paces.
I'd really be very honored if anyone help me figure out how I could (when publishing out to HTML5) no longer have the "undefined" error message show up when using drag-and-drop with a variable for shape text. This technique has been well received at the college I work at...and I have many future project requests for using such an idea on a variety of similar interactions. I'd love see a solution or see if this might be a bug Adobe may be able to fix!
I tried to find a solution to the issue documented here for quite some time, but I was not able to find anyone with this problem much less attempting the idea I'm sharing in the help request - save the darn "undefined" message that comes up!
Many thanks in advance for any help and/or direction that you all may be able to provide,
Paul

Hello,
I just wanted to supply a minor update related to my drag-and-drop question/issue stated above:
I did another test using Captivate 7, and found that the undefined error (publishing as HTML5) does not appear and the variable data remains visible - except the variable data turns very small and does not honor any font size related settings.
I did go ahead and submit this to Adobe as a possible bug today.
Thanks again for any help related to this issue. If the issued documented above is solved, it will allow many amazing things to be done using Captivate's drag-and-drop for both regular type projects as well as interaction development for iBooks!
Matter of fact if this issue gets fixed, I'll publish a Blog entry (or video) on way's I've used Captivate's drag-and-drop to create dynamic learning activities for Higher Ed. and for use in iBooks.

Possible bug with Triggers tab

Hi there,
I'm using 1.0.0.12.15 and think there is a bug with the triggers tab. When I navigate to my table (which has one trigger on it), and then click on the Triggers tab, the trigger shows up multiple times. It's probably not a coincidence that it shows up the same number of times that there are columns :)
Looks like a missing join condition somewhere.
Hope this helps

Tracked this one down too...
SQL Developer is getting the triggers like this:
Select dt.trigger_NAME, dt.trigger_type, dt.triggering_Event, dt.status, do.object_id , do.owner sdev_link_owner, dt.trigger_NAME sdev_link_name,'TRIGGER' sdev_link_type
from all_triggers dt, all_objects do
where do.owner = :OBJECT_OWNER
and dt.owner = :OBJECT_OWNER
and dt.trigger_name = do.object_name
and dt.table_name = :OBJECT_NAME
However, we got other objects (mainly tables) with the same name as the trigger. Not specifying the object type will identify them the same way as the trigger, resulting them all to be included in the select!
Adding "and do.object_type = 'TRIGGER'" will solve the problem.

2. If I call the dbms_job.run a second time I dont see it, its only when I flush the shared pool which simulates the first time I could be calling the proc which is how I found it initially
3. If I call the dbms_job.run outside of a proc I do see it.
4. Watch your IO and CPU if you generate it. Huge spike to coincide with the figures in the trace.
5. 4294967293 is very close 2^32, is also the size of my shared pool so looks like entire pool is being dumped.
6. Have reproduced on 3 instances on 3 separate servers. all same version 11.2.0.2.0 and patch level which is 2012 Q2.
7. change the proc to have the variable commented out and we dont see the dump.
8. I have a call open with support a while now but havent been able to reproduce on their side. Interested to see if someone has OEL 5, 11.2.0.2 instance, can generate it and also an 11.2.0.3 instance and can show its not in that.
thanks.
