Re: Password Protect a Single Tab in Dialog Tab Control

I just wanted to comment on the use of passwords at start up.  I have a program in which I password protect the setup variables with the property nodes using a sub vi to enable / disable the 'visibility' of the controls.  the reason for this is that the program is running a system in line with a production facility providing data on QC.  Therefore it is never shut down or re-started.  For me I have to control access while the software is running and LabView does a great job letting you do this by hiding and enabling certain controls.
BTW, I do all of this without the use of local variables.
 
Another method to do this is to use the vi ini file vi's.  LabView allows you to write custom setup files with custom tags etc for all of your setup variables.  Your program can read this file when it starts up.  You can then have another vi dedicated to the changing of the parameters in the file.  Then just password protect this vi.  Your main program can be signaled to re-load the configuration file if the config vi. changes it.  I have done it this way before and it works very well too.  Don't try it with a program that requires precise timing as disk access in LabView can be slow.

Tab control in one of the tabs of another tab control
One of my colleagues is working with a tab control. He has several tabs. He is trying to embed another tab control inside one of the tabs of the first tab control. He had placed the second tab control inside one of the tabs of the first tab control. But the problem is that the second tab control does not show up (unless one goes to the block diagram and double clicks the second tab control, only then does it shows up; when the vi is closed and reopened its again not there). I told him that I had never seen such functionality (a tab control inside another tab control) in any application but is it somehow possible. All this is required while the VI is not running and is being developed (of course it should work at run time, but this functionality must show while the VI is not running, i.e., this functionality should be non-programmatic. Is it possible. Thanks for your time. Hi rashid, yes it is possible. See the attached example. I see no problems with it.Hope it helps.Mike Untitled_LV71.vi: http://forums.ni.com/attachments/ni/170/323165/1/Untitled_LV71.vi Thanks <a href="../view_profile?user.id=88992" class="auth_text" style="font-weight: bold;" target="_blank"> MikeS81</a>!

Getting XP look with tabbed dialog control and tab strip control
I know how to use a manifest file to get the XP look for the Windows Common Controls 6 group of controls but I also have both the tabbed dialog and tab strip controls in my app and I want those to take on the XP look as well. Does anyone know how? Also, while I am able to get the XP look through a manifest file in my app's folder I should be able to do this without the file having to be in the app's folder. I've read it has to do with compiling with a resource file but I don't know how to do that. Can anyone offer any assistance? Thanks! ...

Re: tabbing order in tab controls
Is there a way to change the tabbing order without having the order on a list or local change also? I didn't take that into account when making the program, should have ordered all the control before wiring it all up :-/ Hi leachdor,When you change the tab order of a specific control in LabVIEW, it must then re-order the other controls in order to ensure that each tab order value is only applied to one control, and that there are only as many tab stops as there are controls.&nbsp; As such, there is no way to simply re-order a single control without modifying other controls. Hi and thanks for the response. I think I may have explained the behavior i'm seeing wrong.&nbsp; Changing the tab order, you have those two little boxes the first showing the changed order number, and the black background one that shows what it was previously.&nbsp; Each time you change one, yep you have to change the order of the rest otherwise you might tab and select two fields at once!The behavior I'm not sure about though, is when I change them to the proper order on the front page, it changes my block diagram.&nbsp; For example if I have a cluster with 3 items in it, and I change the tab order of the items inside that cluster.&nbsp; Then if I had previously used an "unbundle" function prior to the tab order change, and it was all wired up with item 1 at the top, item 2 in the middle output, and item 3 as the bottom output - AFTER the change, those controls...

tab control inside another tab control
Hi. Is it possible to put a tab control inside another tab control. I tried it several times, but for some reason this doesn't seem to work. Can someone confirm this, or tell me what the trick is. Thanks. -- Georges The only way I know to do this is to put a subform on the first tab control. Then you can put your second tab control on the subform. If you do this repeatedly, however, you will find the form loading rather slowly.

working with a tab control with no tabs in design view
I'm using a tab control in Access 2000, and the user requested to have buttons in the form header, instead of the built-in tabs (so that when they scroll down, they can still switch tabs). Now, this works fine. However, when I'm in Design View, I can't access the tabs without changing the tab control's Style back to Tabs. But I want to be able to place controls in that space at the top where the tabs used to be. But if I need to turn the tabs back on when I need to make design changes, then I can't do that. So the result is wasted space at the top of the tab control,...
