How to init numeric display

In my vi i have a numeric display and a button. when button is pressed, some arithmetic calculation will happen (takes abt two seconds) and then result shown on the numeric display. if the result is less than a certain value the text bg will be red, otherwise grey.
I have no problem writing the above vi.
But what i don't know how is, before the result is calculated (before the two seconds is up), i want the numeric display to show empty and green color. how can i do this? overtime the button is pressed, the display should be cleared and grey, until the calculation is done.
Solved!
Go to Solution.

Numeric indicators are always going to show some value. The default value is zero.
But if you want to make it appear to be blank, you could make the font color the same as the background color. Then when the time is up, programmatically set the font color back to the original color to make it visible.

How can I edit text labels in a numeric display?

I have this numeric display, type U16, that displays specific messages, for example 'PASS' when the input is 1. I need to add another message.
I added a placeholder, for input = 3 (verified by the digital display) for the new message by rightclicking/'Add After' but I'm not able to add the new message. I can't edit the text (can't select it) for the existing messages either so I know I'm on the wrong track.
The G programming reference for LV 5.1 (page 9-17) says to use the labeling tool so I tried the 'Edit Text' tool on the tools palette. Is there another labeling tool? Any help is appreciated.
Thanks,
Jeff Bledsoe

Jeff,
It sounds to me as if your U16 ring control is, or is linked to, a typdef (Type Definition), which LabVIEW programmers can employ to impose sharp constraints on the way a control looks or behaves. This would explain why you can't edit the text items, or add one. The bit about adding an item for '3' is confusing, but maybe it has to do with the ring being set to allow undefined values.
I can't recall how to manage these things under LabVIEW 5.1, but in 7.x, I would right-click on the control and see if "Open Type Def" was one of my options; if so, this diagnosis is correct, and you can make your changes only be editing the actual type def. The changes would then automatically be applied to any other control or indicator that is linked to the same type def, which is a very powerful programming technique.
Your best move might be to read up on Type Definitions in your LabVIEW User Manual, or in Application Note 159, and then proceed.
Hope this helps,
John

How to format numeric result in a datatable?

I have a View Object (not tied to an Entity Object) that is displaying a read-only table that includes numeric values.
I'm not able to figure out how to control the display formatting so that only 1 decimal place is shown - right now the numbers are showing more than 10 decimal places.
Is there anyway to control the display format for numerics using either the View Object Editor Properties, or, through using attributes of the <af:outputText> tag on the .jspx page?
Here is what I have defined currently:
In the View Object Editor, the numeric columns are defined as:
View Attribute Tab: Type=Big Decimal
Control Hints Tab: Format Type=Number; Format = ####.## (question does this formatting only apply when editing the field, or also should it apply when I'm reading/displaying from the database?)
In .jspx page:
<af:column headerText="#{bindings.ZipCodeTestView1.labels.Latitude}"
sortProperty="Latitude" sortable="true">
<af:outputText value="#{row.Latitude}"/>
</af:column>
thanks
Tom

hmmm.. I had tried that. What I'm noticing now is that if I test the VO in the BC4J tester within Jdev the format mask is applied. However, when I add the table (as readonly) to a .jspx page and deploy to Tomcat, the format mask is not used when I view the page in Firefox 1.5.0.3 (or Internet Explorer 6.0)? Any ideas?
here's a snippet for one of the columns from the .jspx page:
<af:column headerText="#{bindings.ZipCodeTestView1.labels.Latitude}"
sortProperty="Latitude" sortable="true">
<af:outputText value="#{row.Latitude}"/>
</af:column>

Convert a TTL to RPM numeric display.

Hardware
cDAQ NI 9172
Module: NI 9401
Monarch Instrument’s Remote Optical Sensor (for measuring RPM/pulse counts)
Software
NI Sound & Vibration Assistant
NI Signal Express
LabView
Experience Level
Beginner
My objective is to read and record accelerometer and engine speed data together so they are time stamped the same. Setting the accelerometer up was easy… the RPM, not so easy.
I have been trying to convert a 5v TTL signal from an optical sensor, which is used to measure RPM, in NI Sound & Vibration Assistant. The optical sensor is a stand alone, self powered system with a output signal of “TTL compatible pulse (0 to 5VDC)”.
I’ve started a project in NI Sound & Vibration Assistant, “Add Step”, “Acquire Signal”, “Digital Input” and “Line Input”. On the Step Setup Tab/Configuration Tab, I’ve selected my channel, Acquisition Mode set to Continuous Samples, Rate set to 1.3kHz. Then on the Step Setup Tab/Advanced Timing I had to select “On Demand” for Sample Clock Type due to error message(s). “On Demand” is the only way to get the signal to appear on the Step Setup Tab’s graph. The signal is a square wave represented by 0 and 1 (0s and 1s are overlaid on the graph). When I block the optical sensor view, the signal goes flat represented by 1.
I’ve also messed around “Acquire Signal”, “Counter Input” and “Edge Count” with the same results.
Question: How do I convent this TTL signal to a RPM output… either as a numeric display?
Thank you in advance for any help.

Ferzo,
Great example! I am able to get a RPM numerical value… however when my rotating component slows to a stop, the processed data (logging) stops updating around 500 RPM. I was expecting the value to drop to zero as my source reached zero. Plus some of my speeds, that I need to measure, can be a low as 1 to 100 RPM.
Please note that your screen shot of the formula page is different than mine. Mine is missing the “Input and Output Scalars” window… any ideas?
Thanks,
Team Stoney

6714 init PCI display first problem

I have a MSI 6714 V1 mainboard, that has integrated graphics. Now i want to install a PCI graphics card with TV-out, but no matter how i adjust the BIOS settings, the computer does not want to use the PCI-card. I have tried to disable the onboard graphics card and enable init PCI display first, but it does not work. I have read that others have had the same problem with this mainboard. I have the newest BIOS version and there is nothing wrong with the PCI card. (Powercolor 9200SE PCI).
Any hints?

Well I dont really know... I was just thinking maybe you should read ur manual... Because some motherboards have PCI ports that are previewed for certain PCI cards...
For example: I had a friend.. he couldnt get his soundcard working so then i told him to read his MB manual.. and in the manual it said: "for sound cards use PCI slot 2"... or something like that.... And it worked for him...
I dont know why they do that... I think it has to do with the IRQ's...
As i said.. its just an Idea.. I dont know your motherboard...
sorry

good luck

How to change external display resolution WITHOUT clicking "CONFIRM"?

I have a somewhat unusual situation. My MacBook laptop is actually now a ModBook (a pen-tablet computer), and as such I no longer have a trackpad attached to it. All of my inputs are via the stylus, tapping directly on the built-in display.
This works perfectly fine, except when I need to give presentations on an LCD projector (which is quite often lately). I like to use the projector as an external monitor, so that I can run the Keynote presentation on it while using my laptop screen as the presenter's display, with the upcoming slide, etc. If the projector doesn't give me an ideal native display option (sometimes, the aspect ratio for the 3 or 4 resolutions available in the Displays drop-down in the menubar turn out to be stretched or squeezed), then I, naturally, have to open the Display System Preferences and try out different resolutions.
The problem is, since my stylus only interacts by clicking directly on the built-in-display, I have no way of moving the cursor over to the external display when the dialog box with the "Click here to confirm change/You have 15 seconds..." message appears. So I can never click it ... so I can never confirm the new settings.
The workarounds I've used so far are:
- Mirror displays (not ideal, as I need the presenter preview of the next slide)
- borrow a mouse from someone (usually from a Windows desktop, frankly) and plug that in to briefly mouse over and click the confirm button
I'd love to find a software workaround that allows me to NOT mirror displays and also doesn't require me to carry around a mouse all the time (my laptop bag is already overstuffed...).
Thanks.

How can I just display the selected value of a listbox in a report without the reverse display and selection buttons?

I am using a table which contains a text field with a lookup. I want to use the selected value of this field in a form which is acting as a selection form. No editing of the field's value is permitted. How do I just display the value of the field (which
is considered a listbox on the form) without the reverse display and the up and down selection buttons.
I can provide an illustration of the condition I am trying to overcome, but this system doesn't accept it.
Thank you for any suggestions or clarification you can provide.
Marj Weir

Thank you. I'll try that approach.
I found, after much experimentation, on a similar problem involving a multiselect lookup field, that if I make the field invisible, and add a textbox that displays the fieldname plus .column(0), it displays all the selected entries.
E.g.: staff.Column(0)
Staff is the field containing the last names of selected staff members.
staff.Value only shows the first name in the lookup list whether it is checked or not, so this is useless.
staff.column(0), however, (inexplicably) shows all the selected names, e.g. Jones, Smith, Wiggins.

How to load and display a byte array (jpeg) image file dynamically in Flex?

My web service client (servlet) received a binary jpeg data from an Image Server. The Flex application invokes the
servlet via HttpService and receives the binary jpeg data as byte array. How could it be displayed dynamically
without writing the byte array to a jpeg file? Please help (some sample code is very much appreciated).

JPEGEncoder is only useful for converting BitmapData to ByteArray, not the other way around.
By the way JPEGEncoder and PNGEncoder are part of the Flex SDK now, so no need to use AS3Lib (alltough it's a good library to have around).
To display/use a ByteArray as image, use a Loader instance with the loadBytes method.
    Loader.loadBytes(bytes:ByteArray, context:LoaderContext = null);
Listen for the complete event on the Loader.contentLoaderInfo and get the BitmapData in the event handler.
private function loadJpeg():void {
    var loader:Loader = new Loader();
    loader.contentLoaderInfo.addEventListener(Event.COMPLETE, loaderCompleteHandler);
    //jpgBA is the ByteArray loaded from webservice
    loader.loadBytes(jpgBA);
private function loaderCompleteHandler(evt:Event):void {
    var t:LoaderInfo = evt.currentTarget as LoaderInfo;
    // display the jpeg in an Image component
    img.source = t.content;
<mx:Image id="img" scaleContent="false" />

How to restrict the display of report variants

Hello All,
I want t know how to restrict the display of report variants.
I mean, when a user saves a variant for his/her purpuse on some report program, only he/she can refer the variant while other users cannot.
I know that by setting the attribute of the variant ("Protect Variant ", "Only Display in Catalog"), this would be possible, but I want to know another way, without this setting.
Thank you for your help in advance.
