What did you expect to happen? You have a case structure as the outermost structure on your BD with the tab as the selector! You only read the tab once and execute only 1 case dependant on which tab is selected when you press run.
Try initializing both VISA sessions and chose which one to communicate with based on the val change event of the tab

Tab control problems

I made a peogram to look at the file name back and forth. seefile.vi works great. I also need to do further work after seefile.vi. I created TAB control with two pages. Simply I duplicated seefile.vi (page 1) as page 2, which is seefile1.vi as attached. Now I can not run it right. The problem is Next Buttorn can be used once and then it is running for ever.
If I delete all content in page 2, it works great again. My question is what in page 2 can cause Next Button in page 1 frozen??? Or I did not figure TAB control right.

I don't see any Tab control, I don't see page 1 or page 2, I don't see a Next button, and I don't know what you're talking about. You will have to do a better job at explaining what it is that you want. Also, in one of your block diagrams, you have a loop condition with a False wired to the Stop sign. This will cause your vi to run forever.

Tab control does not show up

Hello, I am still using Labview V8.21 on XP. I know, I know, should be using my 8.6 but do not have a DVD drive.
Anyway, I am trying to do some support on a VI originally written in V6.1 and updated to V7.1 The problem is, there is a tab control on the front panel that will not show up, it is on the block diagram, labview will not really find it, but thinks it is still there, the front panel is just blank and really big. Looked all over, nothing on the front panel. Any ideas why this would happen or how to get around rewritting the whole VI? I doubt a rewrite will occur, as a company we have moved to .NET and the product will probably be either discontinued or redone in .NET if I cannot get a work around here.
thanks.

cannot color the control or the VI to make it show up. Here is a post, this is a big VI and alot of error will show up as I am not posting the whole thing, just the TL vi that has the tab control problem.
This is one thing that made me leave Labview, all eggs are in the VI basket, if it fails, you are done, unlike .NET that you can open the source with a text editor if you have to.

When I resize the font for the Page Labels on the tab control in LabVIEW 7, the Increment/Decrement size gets messed up. Is there a solution to this problem or is this a bug?

I have noticed in LabVIEW 7.0 and 7.1 that when the text in the page labels display is enlarged, that the arrows enlarge but the top arrow enlarges more then the small arrow but then when you decrease the text size, the arrows stay remain large. This is not a problem in 6.1 because the arrows aren't available. Is there a work around for this bug or do I have to use small text for these page label arrows to look right?

I must admit that I've never used the page labels display and it does look like a bug. You can fix it however. Select the tab control and choose Advanced>Customize. In the control editor, select the page label control and do the same thing. You should be in the control editor for the numeric control and then you can go to edit mode and enlarge the decrement arrow to make it the same size as the increment.

Graph range problem with tab control

Hello.
I am using LabVIEW 8.2.1
I have five XY-graphs in a tab control, with five tabs. One graph in each tab. When running, theese graphs is constantly written to, but the user is only allowed to watch one at a time.
The program also contain a maximum&minimum chart, containg the maximum and minimum value for every plot in the viewable part of the graphs. The user can zoom in on a graph, and then watch the max&min values in this picture. The values are calculated by taking the range to each graph, and use theese ranges to cut out the viewable part from the input data to the graphs.
The problem is, that the program only see the last viewed range. If I view a graph in a tab, the max&min values for this graph is correct, but the four other graphs dont get the correct values. The graphs data is written correctly. It seems like the ranges from the "hidden" graphs dont get updated when not viewed. Does anybody know how to fix this problem?
I have uploaded an example to this problem. See how the range just freezes on the not viewed graph, even the two graphs is exactly the same.
Thanks
Fredrik, Norway

Frederik,
the reason for your issue is autoscaling. If the graph is not drawn, autoscaling will not take place, so you will not get any correct values, you will get the last autoscale-values.
The behaviour therefore is "works as intended" since it reduces CPU usage.
So the best way to work around is something like seen in the attached VI: you should compute the scaling for each graph on your own and use this to update the scales as well as the indicators (which i left out in my VI).
hope this helps,

Tab control page Setting problem?

Why I am not able to change the page Label name programmatically. Why the page Label Name property is only readable?

Hello.
If using Labview 7, you must be able to change tab labels programmatically. There is an example called "tab control properties.vi" that shows how to do that.
If using Labview 6 , this link has an example, too.

Make the tab control a control and not an indicator. If you want to write
to it you need to create a local variable.

How to hide a tab in a Tab Control by Property Node?

Hi,
I have a Tab Control in my Front Panel. So, using a array of LEDs, I would like to hide some tabs, probably using Property Node functions, but I can't find what option do it. Is it possible?

Thanks Macro! I came to the forum to find a solution for this exact problem, it's nice to find it already laid out for me so clearly.

Tab control background color matching

I have a system style tab control. I realized the when the program runs in exe mode, the background color of my label on the tab control doesn't match the backgound color of the tab control. The background color of the tab control is different between exe mode and development mode. Anyone help? How do I match the color? Thanks!

Text Tool on Tab Control Bug?

I'm trying to create some free labels on a tab control with the text tool and I've found the postion of the text insertion point is off. When I click anywhere on the tab the text appears a few inches above the point that I clicked on. The tool is working fine off the tabs and when I go to select the previously written text with it that works too. I've noticed the insertion point jumps around and is often in a new place when I open a new VI and drop a tab control down. I have free text on tabs I created last week so I know it wasn't doing it then. Has anyone else seen this behaviour?

Scaling of Tab-Control do not work correct

When I use the option "rescale objects on the front panel when resizing" in the "window size" category inside the VI properties, then my tab control has a wrong behavior. When I increase my window size, the tab control increases correctly. When I decrease it again, the tab control do not decrease and overlays the other controls.
Also a horizontal decoration line becomes a transversal line and my string control seems to scale different from the other controls so I get overlay effects again.
Does anybody know some hints how I can fix this ? If not this feature is not usable and I get some problems with customers with different monitor resolutions.
Many thanks for any idea
Thomas

Yes, there is a known issue with the scaling of tab controls with the window size. This will be fixed in the next release of LabVIEW. For now there is a workaround that might help:
Only scale the tab control as the panel resizes. Leave the "Scale all Objects on front panel as the window resizes" unchecked. Select the tab-control and go to edit->Scale Object with panel. This will not scale the objects within the pages.
In general please refer to this document for further information about misplacements that may occurr with the rescale option.

Export image EMF from tab control, help!!

Hello,
I am trying to get a good resolution report. I got use export image to EMF file so the graphs look very good resolution. When I appended the image control like png it looked poor quality. Now is ok, now I export image of graphs to emf and then use 'append image to report' using the path of file emf.
But I have a problem in this case. I am trying to get EMF file from Tab control. I have 8 graphs inside of each page of tab control. I would like to get each page exporting to EMF file and later append the image to report from path of file. The problem is I cant export to emf. I tried the solution in this treads.
http://forums.ni.com/t5/LabVIEW/send-control-image-programmatically-to-clipboard/td-p/180921/page/2
But it uses get image and it is bmp, so no good solution.
I attached pdf file. IT shows the tab control with append control to report (it is like capture in png file) and one graph append control to report png and emf file of another graph and use the path to input in word report. You can see the diference.
I would like to know if i could export the tab control to emf or any onther vectorial image and later use the path. SInce it will take several pages and i will need sometimes 300-400 graphs...
Any idea would be great.
Best Regards.

Hi Mike,
Thanks for your reply!.
Well, it was only one example. Check the attached file. It works ok. I split in dataset of 8sec and save the emf files.
The problem is the report. If I enable it doestnt works fine, since you will be the both parts working in the same time.
That's why the sequence structure would be ok, one time all the graphs are saved then I could append to report.
I have another question. I used transparent graph and it works ok. I remove all the scales Y values or labels and customized the graph adding one horinzontal line for X scale (like capture), but in the file emf saved didnt appear. Do you know why?.
Best Regards, Fred.

Tab Control/Display Data

Hello All,
I have an issue with displaying large amounts of data. What my program does is calculate INL/DNL errors on analog to digital converters, when the program runs it generates 3 graphs and a couple of numbers. The idea is to be able to run the program a couple of times and be able to compare data from run to run. My idea was to use the property nodes of a "TAB CONTROL" and create a new tab each run through and store the new graphs and data there. Is this possible? I have not yet figured out how to do so. If anyone has a solution to this or advice on how best arrange such items so they can be easily accessed I'm open for suggestions. Thank you for your time.
Regards,
Kenneth Miller

OK, I spend a few minutes to wire up an example showing my idea above (LabVIEW 7.1). It can be easily adapted for more complex problems such as yours. (E.g. add timestamps, add events for printing, saving, etc. ...)
I think it is a better solution than layers of tabs. Enjoy!
