Silver style other style subVI

When I create a control for a subVI it will always use the style used in the subVI. I want to create all my controls in Silver style, but now I am stuck between part silver style and part modern style. Is there a way to bypass the style of the subVI? If not, is there a way to create literally any control without using right-click create control on the subVI?
PS. the last question is my problem mainly with DAQmx VI's. I don't know how to make a physical channel of the exact right type, for instance one that only recognises counters. If I create a physical channel in Silver style in the front panel, I will only be able to select analog inputs, regardless of whether I am connecting to a counter physical channel, analog output or analog input.
I am using Labview 14.01 (64-bit)

Hi Bob,
Thanks very much for your answers. We're not really on the same page yet, I hope my answers to your answers will clarify this. Hope you find the time to reply again.

I'm not sure I understand your question. If you are creating a control on the Front Panel, and your default Palette is the Silver Controls, then any Control/Indicator you place down should be Silver. If you want to convert a Front Panel Control to its Silver counterpart, and Silver is the default palette, you can use Quick Drop. Left-click the Control/Indicator, type Ctrl-Space to bring up Quick Drop, type the name of the Control (e.g. Error In), then type Ctrl-R (Replace). Voilà.
Thanks for the reply. altenbach underston the first question. The subVI's style determines the style of the control you make, the built in functions of LabView do follow what you're stating. Indeed, replacing is an option which I don't mind too much, but I want people who use and adapt the code after me to not have to go through such a tedious and indirect process. I would like to find a way to bypass this feature where controls are automatically in the subVI's style.
An I/O Channel is the same, regardless of the Style of the Control. The value will differ depending on whether the device is Analog or Digital, Input or Output, but you should be able to put a Silver Physical Channel Control on your Front Panel and wire it to any DAQmx function (in the upper left corner, of course). Just "adjust" the content of the Control as appropriate.
I'm afraid you misunderstood my question. I am unable too choose anything else but analog inputs when I connect the physical I/O channel to any "Create Virtual Channel", whether it's a counter, analog output or analog input. The options I can select are limited only to the inputs that actually fit the channel (if I use modern controls), and in the Silver case where I make a physical channel on the front panel I am limited only to the analog output. Indeed, I can make modern controls, select the input I want, convert them to Silver controls and it works. However, I am then unable to change the physical channel without first changing back to modern and selecting the channel I want (for instance I cannot change my counter from Dev1/ctr1 to Dev1/ctr0 without doing this).
I am using Labview 14.01 (64-bit) Why? Do you really need the Address Space, and are you willing to give up the relative lack of 64-bit LabVIEW drivers and other support? Most of us run LabVIEW 32-bit on Windows 64-bit
I have no real reason to run the 64-bit version of LabView. The computer I am using now is not a research computer (just my office computer with an old DAQ board), I'll be sure to think about this regarding the choice of LabView version on the lab computer. Judging from the national instruments link I found it's probably better if I keep to the 32-bit version in the end.

Cosmetic Glitch when Replacing a Silver Style Combo Box by a String

As the title says, if you replace a Silver Style Combo Box by a String (same data type), things turn ugly:
Nothing of the sort happens with the other styles as can be seen above too.

Hi X
Yea I get the same behavior in 2012 and 2013. A workaround for this would be to replace the original control or indicator with a non-silver version of the control and then replace that control with the desired silver style control. This seems to work for me.

Odd Silver Style String Replacement Behavior

I have got a Typedef Cluster built using the Silver Style:
Later, I decided to create a new Typedef String (also using the Silver Style):
Then I decided: let me replace the first element of my Typedef Cluster by the (better looking) Typedef String I just created.
I am not doing anything fancy here. I am just right-clicking the string in the cluster and choose: Replace>> navigate to the folder where my "Burst Statistics Definition" Typedef String is located and click OK.
Here's the result:
For some reason the string has been squeezed to a ridiculously small height, which I suspect is that of the original string minus the decoration of the silver style.
Worse, if I expand said string to the next largest size, it snaps to the following:
Notice how the background has absolutely nothing to do with the default Silver String.
The only way to get out of this nightmare is to first replace the String in the Typedef Cluster by a non-Typedef Silver String and THEN ONLY, replace the Sivler String by the Typedef Silver String I wanted to use in the first place.

I think "intended" is the word. It is certainly not the user-expected behavior. I doubt anybody doing what I was doing would expect the squeezed string result. Instead, I think it is fair to say that most would expect a frame to be added around the frameless string (therefore expanding the footprint of the string control). Think about frameles glasses versus glasses with frame.
I must correct my statement above: I think the original string control might have been a frameless silver string.
If I drop a simple frameless silver string on the FP and replace it by a standard silver string (with frame), the squeezed aspect and dark background is evident (no need to go through typedefs).
Tested in LV 2012 12.0f3 (Windows XP 32bits).

Silver style array

I kind of like the new silver style but I do not like the new array style.
For instance here is the default layout for a 1D DBL array:
What is that void around the numeric control? It looks like it is floating above the array object...
Wouldn't have been easy to use a style similar to the matrix object? (but limited to 1D):
Solved!
Go to Solution.

I am adding this remark, which belongs to the gray area between a stylistic feature and a design bug:
There is a 2-PIXEL SHIFT between the index display and the silver style array frame:
Of course, this is easily corrected by Edit>> Customize Control and shifting the index:
but why do we have to do that?

Why do the LabVIEW examples that use the queue design have one loop in the top level and all the others as subvis?

Specifically the Weather Monitor example under connectivity/Web Services and the FPGA design examples.
There are several parallel loops. One of the parallel loops will be in the top level VI. The others are all in sub-VIs. After the third example I was looking at it seemed obvious this was being done as a standard, but I don't know why it matters.
Why not all of them as SubVIs? Why not all of them as top level loops? (Well OK maybe not that one.)

For me, it depends on what is happening in the parallel loops. When I have modules that just need to run in parallel with the main loop, it helps reusability to have it a a subVI call. I can then just copy that library to another project and use it.

Silver Combo Box Display Style Bug

[LV2011, Windows XP]
There appears to be a small bug with the Silver-style Combo Box control when you right-click and select Visible Items->Display Style. For the string control a glyph appears properly, but for the combo box the glyph appears in the wrong place, and the colours are wrong. In fact, the glyph only appears properly if you click on it, or do something else to force a redraw of the control.
This combo box is a bit confusing, since it has no "Radix Shadow" part like the string control does, and in fact only the Silver-style combo box lets you display the "Display Type" glyph. The other styles of combo box have no "Display Type" feature in the "Visible Items" menu, but the "Display Style Visible" checkbox does appear on the "Appearance" tab of the Properties dialog box (though checking it has no effect, and it appears unchecked if you re-launch the dialog box".
I've attached a new version of the control which is close to fixing the bug, but the glyph region is 1 pixel skinnier than the string version. Copy this to your "..\vi.lib\silver_ctls\String" folder if you want it to replace the version in the palettes.

Good catch, there is now a Corrective Action Request filed for this issue. It is correct that this property is
not supported by the Combo Box found in the Modern Palette. However, this should at least be documented in the
"Display Style Visible" property documentation if this is case, which it is not.
Thanks for alerting us to this error and if you would like to follow the CAR, look for CAR# 312717 listed in

ok so, getting everything in place/revised per you suggestion resulted in the "tiling" of the images in all 3 browser
When I remove the "<div> from the individual images.... tiling goes away for (chrome/Firefox) not for IE... and no functionality for any.
HOWEVER... I get proper preview, with functionality using the following (code below) but ONLY in DW preview mode. If I preview in any browser... tiling. Could it by any be a matter of when I preview it in a browser that the "src=" paths are not correct for the scripts? Hence DW is able to preview it (pulling from localdisk) and browser preview does not have the correct paths? I've ran into that befoure [src="js/script.js"   compared to   src="/js/script.js"]

Silver numeric controls

Hi,
I noticed a small bug while converting some front panels to silver style in LV 2014.
If you replace a numeric control of another style, which has display increment/decrement buttons turned off, with a silver numeric control then the silver control appears with the buttons missing but the thicker boarder where they would be in place. If you cycle the increment/decrement buttons on then off the thick boarder vanishes
e.g replace this modern control (with buttons turned off)

I thought I had but lets try again
Replace this modern control with buttons off

Cycle buttons on then off to get

Is there a Silver (palette) Variant control?

I've been (consistently) using Modern controls, but for a new Project (and a spiffier-looking Front Panel), I started using controls and indicators from the Silver palette. So that my sub-VIs have some visual consistency, I wanted to use Silver there, as well (I especially like not having to change the names of the default Error In and Error Out to "Error In" and "Error Out", which has been my own "style" with the Modern controls).
I can't find the Variant control (which I want to put inside a Silver Cluster). Is it simply "not there" (and are there plans to create it, given that this is no longer the Silver Anniversary of LabVIEW?). If so, are there hints on how I could "build my own"? If not, where is it?
Bob Schor

The Silver controls were designed for user interfaces, not as a general replacement for Modern controls, so there are some controls that do not have Silver versions. (There are also some Silver controls that we want but haven't gotten staffed to implement yet, e.g. tab controls and radio buttons).
However, someone inside NI wanted a Silver Variant recently and made the attached version. It looks pretty good without the scrollbar visible, but unfortunately the scrollbar is drawing at the wrong size and I don't think I can fix it without making changes to the LabVIEW executable itself.
It is possible to "make your own" Silver style controls using the Control Editor - you can copy/paste the decorations from the Silver controls into the parts of other controls. There are limitations, however, such as not being able to edit some things (such as scrollbar style) in the Control Editor.

LabVIEW new "Silver" error cluster and TestStand

I have some new VI's that use the new "Silver" style error controls and indicators. I started calling the VI's from TestStand and noticed that the new VI's were not auto populating the TestStand error to the VI's error out. Not sure how this mechanism works but it doesn't work with the default "Silver" controls. I think it is name based case sensitive and I just have to rename the "Error Out" cluster to be lower case "error out".

Paul -
Can you confirm that the problem you're describing is that because the name of the Silver error cluster is "Error Out", when you configure a LabVIEW step to call a VI that has the Silver error cluster wired to the connect pane, TestStand does not automatically assign Step.Result.Error to that parameter? If so, we have reproduced this behavior and yes, you are correct that it is due to case sensitivity. We have taken note of this in order to fix the problem in a future version of TestStand.
I also just wanted to confirm that the problem is not that the error information is not correctly passed from LabVIEW to TestStand, when you assign Step.Result.Error to a Silver error cluster parameter.
Please let me know.

Round Color Box (Silver): Slows VI Server Access

Continued from here:
Christina (et al),
I've attached two examples demonstrating the obervation. I first ran into this because I use a simple flags framework in some of my applications. If the flag name input is unwired, I auto-name the flag based on the calling VI name. So, I get a reference to the calling VI and determine a flag name respectively as you can see in the attachment.
The "Wait for Flag" primitive can be called in a loop as quickly as you like (limited by how long it takes to access the calling VI reference of course). So, I had an application where the consumer loop had to run in the 100+ Hz range and because the Round Color Box (Silver) was on the panel, I couldn't get this kind of performance. Switching to the Round Color Box (Modern) solved the issue (but doesn't look nearly as nice).
The "test color boxes_Rapidly Access VI Refnum" example below is a simplified version illustrating the problem. The "test color boxes_Wait for Flag" example better represents what I'm actually doing. Just unzip and run the "test color boxes_Rapidly Access VI Refnum" VI and follow the instructions on the panel.
Then, unzip and run the "test color boxes_Wait for Flag" VI for an actual use case.
Thanks for taking a look. Do you see what I'm seeing?

The problem here is that the "Silver" style frame draws relatively slowly. In most cases, this isn't noticeable because LabVIEW doesn't need to redraw the frame when the value of a control or indicator changes. But, when the control is an element of an array, LabVIEW does redraw the entire control for each element value change.
So, for the time being, I'm afraid it's not advisable to use Silver controls (other than the "frameless" ones) as array elements.
You can see that it's the frames that are causing the slowdown by coloring them transparent so that they're invisible.
I'm embarrassed to mention this, but the coloring trick also shows that there's a workaround where you take a picture of the array of Silver color boxes, put it in the background, and then color the frames of the actual color boxes transparent. I'm not saying it to recommend it, just to say that it does get you something that looks the same without the performance problem.

SubVI

I am opening three subVI's in the subpanel in my main VI depending upon the menu chosen. Then, I need to enter a filename and some numeric values in one of the subVI, open that binary file and perform some operations with the data depending upon the numeric values entered in the subVI and display some results in the other two subVI's. Right now I am able to just open the subVI but not able to close them using the close button of the subVI's . I am also not able to read the filename and numeric data entered in teh subVI. Can anyone please help me to read the data from subVI?

Hi,
To obtain the values of your controls in the subVIs, you'll need to wire the reference to your VI by an invoke node "Get Control Value [variant]". Then you can use "set control value" to pass the values to the next subVI.
Close button in your subVI will not remove it from the subpanel. You can try using the get control value property node to obtain the status of the stop button, and use subpanel's Remove VI invoke node to remove it from the subpanel.
You can start by checking the examples in the NI Example Finder. Look under Build User Interfaces/General/
simple.vi, templates.vi and viewer.vi
Hope this helps,
Dan

Ipad mini space gray or silver?

I really don't know what kind of Ipad mini I am going buy. Space gray is ok for me and so is the silver color. I dont know what kind of color will hide the scratches, dirt, dust and grime. So what color is good and okay??

I'd go with the silver but either color is OK. More important get the black bezel, it frames the screen better and goes good with the silver.

How is the new keyboard?

I was planning to pick up a new MBP today but when I took a look at it in the store, I wasn't impressed with the feel of the keyboard. I've got a first-gen MBP and I do a LOT of typing so I'm pretty used to the keyboard on it.
The keys on the new one felt smoother than my MBP does, almost like there was no texture at all. And the spacing felt a little different as well.
I realize it's hard to judge from 10 minutes of use, so I'm curious how other people have found the switch, especially if you do a lot of typing. Do you like the new style keyboard? And did it take long to get used to the change?
Thanks,
John

I was used to and comfortable with the older style keyboard and the newer one did feel a little strange to start with - doesn't everything? Now I prefer the new style keyboard to the old.
As for grease, oily finger marks - I personally don't have an issue with this. Indeed, the smooth black finish might show certain marks a little easier, but the older silver-style keyboard was far from perfect in this department either. On my old G4 PowerBook, after a few months of what I would classify 'normal' use, I would start to see a grayish grime around the edges of the more well used keys and would need to wipe them clean.
