How to lock block diagram alone from editing leaving front panel for editing?

i want to lock block diagram from editing but front panel can be edited for creating controls, moving controls editing properties...

executables will be delivered to customer and they can create new vi and edit frontpanel and link tag through databinding. but i dont want them to open block diagram...
Natasftw is right - you seem confused about the difference.
If the customer can "create a new VI and edit frontpanel" then they have to have LabVIEW Development System.
If you give them an EXE, and they don't have the DevSys, then they can use your VIs, but not edit them or look at the code.
If they have the DevSys, then they can edit your VI and look at the code, UNLESS you protect it.
If you save a VI with protection (VI PROPERTIES - PROTECTION ) then you can LOCK it (user has to explicitly unlock it with an extra step), or you can PASSWORD PROTECT it (user has to explicitly unlock it by giving a password).  Either way requires the DevSys.
There is no situtation where one can edit the front panel without being able to edit the block diagram.

  • How do I get the Label for a Front Panel Control to appear in the Block Diagram but not on the Front Panel?

    How do I get the Label for a Front Panel Control to appear in the Block Diagram but not on the Front Panel? On the Front Panel I am making a complex control that consists of a Slider and a Numerical Input box. Both Controls display the same information and either can be used for Input. When one changs, the other is made to display the same value.
     But I only want the Slider to display the Label on the Front Panel, to avoid confusion. On the Block Diagram however, I want both controls to display their Labels so that I know what they are. How do I display the Label for a Control on the Block diagram, but not display its Label on the Front Panel?

    No.  The Label Visible property is separate for the front panel control label and the block diagram terminal label.
    How did you start out with the block diagram's label not being visible?  Whenever I drop a control or indicator, the label is always visible on both the FP and BD by default.  Maybe there is a LabVIEW option that causes new controls/indicators not to have their labels visible by default, but I have yet to find it.  I don't think an item should ever be dropped without the label visible, good LabVIEW coding practice demands that the labels for control terminals on the block diagram be visible so that you know what control or indicator a wire is going to.
    That being said, I have seen a lot of VI's posted where the label for the terminal on the BD is not shown (against good programming practice.)  I've gone to the BD and right clicked to show the label.  Sometimes, the people have an empty label (which will turn off the visibility for both the FP and BD) and I'm forced to add some text of my own into the label so I can figure out what their code is doing.  When I add some text to the label, at that time, I find both the BD and FP labels become visible.
    Are you dealing with controls that have empty labels to start?
    Good programming practices:
    1.  Always have a name for all of your controls, never use and empty label by deleting the text in the label.
    2.  Make the labels unique.  For example, don't have two controls both called Stop.  How do you know quickly know which terminal relates to which control?
    3.  Always show the labels on the block diagram, so you know the function of a control's terminal.  If you want to hide the label on the FP, that's okay.
    4.  If you want a different label to appear on the FP than whatever you actually called the control, then use the caption.  You can hide the label and show the caption.  This is useful if you need to programmatically change what the "label" is on the front panel such if you are making an application that needs to change its user interface such as for a foreign language.

  • HOW CAN I BLOCK SMS MESSAGES FROM AN SPECIFIC PHONE NUMBER ON MY IPHONE 5

    HOW CAN I BLOCK SMS MESAGES FROM AN SPECIFIC PHONE NUMBER ON MY I PHONE5, THANKS

    You can't. Contact your carrier and ask them if they provide such a service. Most carriers do not, unless the text messages are threatening or harassing, but you can ask.

  • How do I block this msg from always popping up "iTunes requires Safari 4.0.3 or later to be installed to use the iTunes Store within iTunes. Use Software Update to download and install the latest version of Safari" bc I can't download the latest software?

    How do I block this msg from always popping up "iTunes requires Safari 4.0.3 or later to be installed to use the iTunes Store within iTunes. Use Software Update to download and install the latest version of Safari". I cannot download this software bc my lap top is to old. The msg literally pops up everytime I make any moves on itunes and is VERY annoying.

    I have a 2006 MacBook with an Mac OS X version 10.5.
    In that case, try downloading a Safari 5.0.5 for leopard from the following location:

  • How do I move a file from "Recents" in Adobe Reader for Android to a folder in "Documents"?

    How do I move a file from "Recents" in Adobe Reader for Android to a folder in "Documents"?
    Files from Google Drive are appearing in "Recents" where I cannot organize them hierarchically.
    I cannot find a user manual for Adobe Reader for Android with this level of detail.

    Hi John,
    Files opened via Google Drive are not listed in ‘Documents' section of Adobe Reader, because they are read only files. If you really want to save these files to ’Documents' then please follow below steps -
    Open the file from Google drive in Adobe Reader.
    Tap on the Comment icon placed at top toolbar(Second icon from the beginning)
    You would encounter a 'Read-Only document’ dialog, tap on Save button.
    Once you performed above steps , your file will be saved in /Download/Adobe Reader/ folder.
    Hope this will solve your problem.
    Thanks,
    Adobe Reader Team
