How to make current value to default to all controls at once

Choosing "Data Operation" -> "Make Current Value Default" to multiple controls requires a lot of clicking. Is it possible to do this with one click?
Solved!
Go to Solution.

Yes. If you select no controls, it says "Make current values default", and it does all the controls at once. If you have a control selected, then it does only the selected controls.
Reinitialize current values to default works the same way. Select nothing, it does all the controls at once.

HI sridhar,
this can be done with SHD0
enter shd0 , enter cj34 in transaction code ,zcj34 in transaction variant, click create this wil take u to cj34 screen .... here u tick the overall values and press enter this wil pop up screen variant of cj34 here u mark w.content and output only against overallvalues and click exit and save and save the transaction variant as local object to $tmp package and test that and assign the same to one user group.....

Make current value default - Undo action

Hi,
A simple question - when selecting with the right mouse button a control and pressing "Data Operations/Make Current Value default" how I can undo this operation? Imagine I set some control default value to something and after some time I changed my mind and I want to return the control to its initial value (as it comes when you place the control from the pallete - "Set to factory value"). I was not able to figure out how to do this. Cntr - Z is not an option since it works only in the close vicinity of the operation (you can't Cntr-Z this operation after 2-3 hours of intensive work over the VI).
For example I set numeric control default value to 22, after some time I want to return it to initial state (in this particular case the "factory value" is 0). Well, I can reinitialize the value to 0 but it's different from setting it to "factory" settings.
Thank you

I disagree with the idea that the default value is not a valuable tool.
One example is let's say you have a subVI that had a hardcoded constant, but in new applications, this value is to be fed in from the outside - i.e., the constant is to become a control connected to the connector pane. This subVI is in a common library so it needs to maintain compatibility with older applications.
So you right-click on the constant to make it a control with the default value already set to the original constant value, connect it to the connector pane and set the connector to anything but required. Now the new software has a connector to hook up to while, even though the old code will have to be recompiled, it won't break because, even though there is nothing wired to the control, the default value works just fine.
I can think lots of other things, but that is among the most useful thing I've done with default values.

Make current values default

Hello ng,
Can anyone tell me how to programatically make
the current values of all controls on a panel the
default values?
Furthermore, can I set all controls back to their
default state programatically?
Thanks!

Are we talking about LabVIEW 5 here? If so check out the VI Server
functionality.
In the Functions palatte under Application Control you can open a VI
reference to
a VI with Open VI Reference and then using the Invoke Node you have both
"Make Current Values Default" as well as "Reinitialize All to Default
available".
These functions match exactly the same commands in the Operate menu.

Invoke Node - Make current values default

I have an issue similar to many postings regarding the use of an invoke node to set control values and then to make those values default in that I get an error message: "Error 1000 ( The VI is not in a state compatible with this operation)."
The catch is that it is not all the time.
I am trying to set up a configuration utility which allows configuration or modification of settings of channels and serial ports. This top level VI pulls values from a configuration file using a mid-level VI which, in addition to loading the configuration file, also calls a further sub VI which initialises and sets as default front panel objects on a number of VI's using Invoke Nodes. Thus there is a heirachy of three VI's
with the lowest level VI doing the Invoking.
The only time I get the Error 1000 is when I try to run everything from the top level VI. From any lower level the VI's run with no problems and the defaults are set as desired.
Any suggestions as to the origin of the problem?
Ross.

To complement the other answer that explains why it not always works, I would again and again stress that !! make current values default !! is not the way to go when you want initial values to be changed.
For changing startup values you should use .ini files !

VI to make current values default

Hi, I've used this website:
http://www.originalcode.com/SavDef.htm to create a method that
will call the "Make current values default" at the end of my program.
Here are my Save defaults.vi and Save defaults core.vi
The latter works but the former gives me a bad input error... I admit I
am not advanced enough in Labview to fully understand these two
programs so I just built them both visually from the website, as I need
my larger program to save the current defaults when it's done running.
Thanks for any help!

It's difficult to explain (and unfortunately I don't have much time).. but the 'Set Control Value' methods in the Save Defaults.VI are actually setting the values for the controls in the Save Defaults Core VI. You instead had constants. I changed these to Controls and named them accordingly (i.e., "occurrence" and "VI to save"). See attachments.
I am guessing "Relative position.vi" is your VI where you wants the defaults to be saved. So, you will add the Save Defaults VI as a sub VI in this VI. You do not have to explicitly give its path anywhere as that is obtained from the call chain.
I have not tested this.. but it should work now. You will have to rename these to the original names, including spaces, etc. (or change the names on the diagrams).
Hope this helps.

Reversing the Make Current Values Default command

Hi,
I was working with a labview program this evening and had been using the 'Reinitialize all to default' command under the operate menu to clear all of the waveforms on my screen. However, I accidentally chose the 'Make current values default' command and cannot erase what shows up in the waveforms. I am sure there is a simple fix to my problem but I couldn't figure it out. I tried rewiring parts of my block diagram do exclude the waveform graphs with the hope that the waveforms would go away but realized that the graphs weren't wired so nothing was going to change. Any help would be appreciated.
Thank You,
bsteinma
Solved!
Go to Solution.

There are a few simpler ways than closing and reopening the VI.
If you realized the mistake right (or soon) after you did it, a ctrl+z will undo the operation and you have your old defaults back.
If you are past that stage, a simple "menu...file...revert" will revert the VI to the last saved version. No need to exit and reload.
If you accidentally saved it with the new defaults, "right-click the graph...data operations...clear graph", make default, save VI again.
Good luck!

Setting Current Values as Default in Stand-Alone Application ?

Hi
I have a stand-alone application using LabVIEW run-time and I want the user to be able to make the choice if he wants to retain the default values or modify them ? I know you can't use the invoke node and set the current values to default because that works only in EDIT mode. I saw some postings where there was a talk about using configuration VIs. I am not sure how to use them. Also is there some other way I can accomplish this ?
Thanks
Sridhar
P.S: I use LabVIEW 7.0
Kudos always welcome for helpful posts

I would use a configuration file to hold default values for my controls. When the vi starts, prompt the user to select default values or to modify. You can use a two button dialog to do this. Wire the output to a case structure. If the user selects default, read the config file and use the values to set your controls values. If the user selects modify, call a subvi that gives the user an interface to modify the values. You can start with the old default values. This subvi would have a loop, waiting for the user to press either a cancel button or a change button. If the user makes changes and presses the change button, exit the loop and write these new values to the config file. If cancel is selected, exit the loop and do not write to the config file. Upon returning to the main, read the config file and set the control values accordingly. You can even go a step further and create a "factory default" file. This file would be read only. The user can be given a choice to select this file in case he made changes and saved them to the config file, and the new changes were all screwed up.
Config files are nothing more than a file containing keys which represents controls, and the data values for those controls. There are examples located at \examples\file\config.llb.

How to set current data as default when stop VI automatically?

Each time, when I finish a VI, I want it remember all current value so that I can reuse it next time. I want this can be done by program itself.
Any idea, thanks

Hello,
If you are using LV 8, there is a built in function to perform a "make current value default" at end of you VI.
If LV 7 and older there are some tricks, that have been explained and re-explained on the forum, so do a search with "make current value default" and you'll find all you need.
Hope this helps.

How to make visible value attributes of a Search Node

Hi All,
We have a requirement to enhance the search context node SEARCH ( Dynamic Query Object SVYQ ) of component SVY_S.
But the enhancement category of Attribute Structure CRMST_QUERY_SVYIL is 'Can't be enhanced'.
So we are adding value attributes to this context node. How to make this value attributes available in view configuration tab?
Please suggest a better approach if there is any.
Thanks in adv.

Hi Suchindra,
You assign these enhanced attributes to design layer. so you can see these fields in Config tab.
How to do:
IMG->Customer Relationship Management -> UI Framework -> UI Framework definition -> Maintain
design layer
Here include the enhanced attributes and then go to component work bench and in context attributes right click assign the desing layer, selct your attribute and in the bottom click on SAVE button.
Then check it in configuration tab your attributes will available in show available fields.
I hope this will solve your problem
