Is it possible to let Labview create displays himself dynamically?

the number of displays can´t be fixed right now.
i want to create a huge number of display by using a menu "create a new display". everyone should show another value from a global variable (Array).
So i don´t want to use static elements - if i would do so, i had to create about 80 digital displays, 20 analog display and a few graphs. But i don´t need them every time - sometimes i need 3 digital and 15 analog displays, another time i need 60 digital an no analog displays. i only want to create 3 foundamental dislays and use them very often with different properties and pointers to the global variable!
Is this possible?
Thanks a lot...

I have in many applications done this by using the picture control. Jean-Pierre first suggested an excellent approach to this in this link.
http://exchange.ni.com/servlet/ProcessRequest?RHIVEID=101&RPAGEID=135&HOID=506500000008000000A33B0000&UCATEGORY_0=_49_%24_6_&UCATEGORY_S=0&USEARCHCONTEXT_INCLUDE_0=Ben+picture&USEARCHCONTEXT_INCLUDE_S=0&UPostedFromTimeSearchArg_0=8&UPostedFromTimeSearchArg_1=3&UPostedFromTimeSearchArg_2=2000&UPostedFromTimeSearchArg_S=4&UPostedToTimeSearchArg_0=4&UPostedToTimeSearchArg_1=9&UPostedToTimeSearchArg_2=2004&UPostedToTimeSearchArg_S=4&USEARCHCONTEXT_TIER_0=2&USEARCHCONTEXT_TIER_S=0
You can use the "Invoke Node" to get the image of a control. If you combine this method with events configured for the picture control, you can simul
ate normal LV objects.
This method takes a bit bit of work, but it does allow the GUI to be taylored as your end user requires.
You do not have to re-code all of the normal behaviour of your control elements. When a clcik is detected on a simulated device, a real LV FP object can be made visable and moved from its off-screen location to where the user clicked, and key-focus transfered. The user then interacts with the LV object that is on top of the the picture if it.
It is not easy, but it works great!
So as to:

Tdms-files: Is it possible to prevent LabVIEW and DIAdem from creating .tdms_index files?

Hello,
is it possible to prevent LabVIEW and DIAdem from creating .tdms_index files when opening/creating/editing a .tdms file?
I think I have no benefit from the .tdms_index files because our applications create a lot of little .tdms-files (repeat measurements). With the additional .tdms_index files we have unnecessary memory consumption and it takes longer for Windows to open the containing folder. Also it´s confusing when searching for a certain file.
Best Regards
Daniel
Solved!
Go to Solution.

Hi Baui,
I'm afraid there's a direct way to disable creating .tdms_index file now from LabVIEW and DIAdem. You can use TDMS Advacend API in LabVIEW, which doesn't create any index file, or you can just make some simple programming and delete the .tdms_index file after closing the TDMS file.
This is a request for a long time, we'll consider to add this feature for TDMS in future releases.

Is it possible to run Labview ver 6.5 with PowerPC as the target CPU and VxWorks as the target operating system? If version 6.5 does not support this configuration, do any of the later versions support it?

I have an Ada executable that's creating a buffer of data that's being fed to a Labview executable that's displaying the data in a GUI. We're re-architecting some legacy system hardware and I'm just trying to figure out if this configuration is even possible.
Thanks

Bug (possibly?): SelectManyShuttle fails to display selected items

Bug (possibly?): SelectManyShuttle fails to display selected items when valuePassThru="true" in ADF 10g
Hello all,
When run, the example below shows a Select Many Shuttle with four choices in the leading list. When items are shuttled to the training list and the page is submitted the trailing list is rendered with no items selected. Is this a bug?
Configuration
This example was constructed using jDeveloper 10.1.3.5.0.
A new application was created using the Web Application [JSF, ADF BC] template although no business components are used.
Steps to Reproduce
1. Create the following backing bean class.
package com.fmcna.adf.test.view;
import java.util.ArrayList;
import java.util.List;
import javax.faces.model.SelectItem;
public class ShuttleBean {
    public ShuttleBean() {
    private List availableItems;
    private List selectedItems;
    public void setAvailableItems(List availableItems) {
        this.availableItems = availableItems;
    public List getAvailableItems() {
        //populate with a List of SelectItem instances on the inital call to this method
        if(this.availableItems==null) {
            this.availableItems=generateSelectItemsList();
        return availableItems;
    public void setSelectedItems(List selectedItems) {
        this.selectedItems = selectedItems;
    public List getSelectedItems() {
        return selectedItems;
     * Build a List of SelectItem instances to be used by an af:selectManyShuttle
     * @return A List containing SelectItems instances
    private List generateSelectItemsList() {
        List initialItems = new ArrayList();
        initialItems.add(new SelectItem(new Integer(11),"First Choice"));
        initialItems.add(new SelectItem(new Integer(22),"Second Choice"));
        initialItems.add(new SelectItem(new Integer(33),"Third Choice"));
        initialItems.add(new SelectItem(new Integer(44),"Fourth Choice"));
        return initialItems;
}2. Configure the ShuttleBean class as a session scoped managed bean as in the following faces-config.xml file.
<?xml version="1.0" encoding="windows-1252"?>
<!DOCTYPE faces-config PUBLIC
"-//Sun Microsystems, Inc.//DTD JavaServer Faces Config 1.1//EN"
"http://java.sun.com/dtd/web-facesconfig_1_1.dtd">
<faces-config xmlns="http://java.sun.com/JSF/Configuration">
<managed-bean>
    <managed-bean-name>ShuttleBean</managed-bean-name>
    <managed-bean-class>com.fmcna.adf.test.view.ShuttleBean</managed-bean-class>
    <managed-bean-scope>session</managed-bean-scope>
</managed-bean>
<application>
    <default-render-kit-id>oracle.adf.core</default-render-kit-id>
</application>
</faces-config>3. Create a JSP page containing an af:selectManyShuttle with a nested f:selectItems component. Wire the values for these components to the properties in the managed bean.
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<%@ page contentType="text/html;charset=windows-1252"%>

<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f"%>
<%@ taglib uri="http://xmlns.oracle.com/adf/faces" prefix="af"%>
<f:view>
<html>
    <head>
      <meta http-equiv="Content-Type"
            content="text/html; charset=windows-1252"/>
      <title>testShuttle</title>
    </head>
    <body><h:form>
        <af:selectManyShuttle value="#{ShuttleBean.selectedItems}" valuePassThru="true">
            <f:selectItems value="#{ShuttleBean.availableItems}"/>
        </af:selectManyShuttle>
        <af:commandLink text="Postback"/>
    </h:form></body>
</html>
</f:view>4. Run the JSP. Validate that the trailing list is initially empty.
5. Shuttle one or more items to the trailing list and click the Postback button. Validate that when the page refreshes the trailing list is again empty.
Thanks for any input you might be able to provide.

I'm holding my Nano in my hot little hands with ALL of the things you listed, but here's the sad, simple truth: you CAN'T use iTunes to sync everything. It works well for:
1) Music
2) Videos (except sometimes in Vista)
3) Photos (as long as they're not too large)
but is terrible for:
1) calendar
2) contacts
3) To-Do lists
For the latter use something like "iGadget" (www.ipodsoft.com). I also edit/store notes w/iGadget plus it allows you to export files, etc.
I gave up on syncing iTunes w/Outlook long ago. Good luck.

In Address Book, why does Apple let you create custom fields in the Template cards but not have them available for importing?

I open Address Book, go into Preferences, select Template and under the Names field (friend, assistant, father, etc) I add a custom field called "Principal".
I also add two more custom fields in the Email area.
Quit Address Book then relaunch. Add a new contact and the new custom fields, Principal, etc. are there. All good so far.
I have a Now Contact file with about 200 contacts in it. I export all fields as a Text file, Tab delimited. No problems there. With Address Book launched, select Import, pick the text file, leave Text Encoding on Automatic and click Open.
The window that shows the fields for Address Book and fields for the text file side by side opens. This is where you match up the correct fields for importing. If I go to one of the fields from the text file that I created a custom field for, click under the Address Book heading on the Do not import, scroll thru the Apple choices of fields, none of the custom fields show up. Only the original Apple ones are there. Why does Apple let you create them in the Template area but not have them available for importing? Does anyone have suggestions on getting around this?

While most likely not of interest to you, Spotlight can also tell you where the files it finds are located
Hover the mouse pointer over the name, and press Command-Option and the path to the file will be displayed.
As for opening a terminal session in the directory where a file is located, there is Applescripts that do just that as well as specific features in Lion/Mountain Lion terminal:

Let's create a walkthrough for booting ppc's from usb2 drives!

What started as a personal project has now evolved into a call for a community collaboration. I think there's a new trick here that should be more available to the ppc using public. Let's create a walkthrough for the public that is complete, concise, and fool-proof.
I have been trying for days to figure out how I can create a bootable drive with what i've got;
PowerMac G5 quad, 500gig drive, 350gigs used, over 200 gigs of unimportant stuff.
Seagate external USB2 drive, 150 gigs, let's beta this puppy out til we get this
bondi blue, 80 gigs, no attachment, no remorse
History:
I have been trying to use my 150gig usb2 external drive to create a bootable drive. The general theory WAS, apparently, that ppc's cannot boot from usb, only firewire - but now intels can boot from either. I've read in many, many posts that USB drives CAN be booted from using a ppc, by either using SuperDuper to do a complete cloning, or booting from Open Firmware and using some scripts.
I can't get either of these to work, and it's probably because i did something wrong or there isn't a solid resource out there on this topic. I think it's because my internal hard drive is bigger than my external, so any cloning i do has to omit folders (movies, pictures, music only) and just isn't a 'complete backup'.
Posts have said that SuperDuper does something that has allowed USB2 drives to be bootable on a ppc without Open Firmware, even appear in the startup disk preference panel!
I just can't get it right, somehow, although plenty of others posted positive results with the same architecture. Is there a way of getting a good install on the usb drive? Can you give me a good walkthrough of the way to go about booting to it?
Next idea:
I have an old Bondi Blue, with 80gigs in it. Perhaps i can use this as a workaround to overcome the size issue (my internal drive being larger than my available external drive).
There's nothing important on the Bondi's hard drive, I just keep it around for OS 9, in case I need that (haven't since I was fourteen years old, though). So I thought, perhaps I can ethernet it to my powermac, reformat the drive and use it as an external drive. Then I bet I could use the install dvd to put 10.4 on it (though it won't run with anything past 10.3.1, just using it as a hard drive i could, right?). So I'd have to boot the bondi blue in some particular fashion; what would that be? As a 'slave drive' or something? Will I be able to boot from this over the ethernet cable?
If this is succesful (or first of all possible) then I could mount both the bondi (as an external/network/some kind of drive) and my usb2 hard drive to the PowerMac. With disk utility or SuperDuper, I could restore/clone the bondi to the USB2 drive, and Blam! the USB2 would have a clean install of os 10.4 that i could (maybe?) boot from with Open firmware. Then I could reinstall OS 9 on the bondi (i've been wanting to give it a fresh start anyway).
here's what i've been reading, and it's confusing, contradictory, and without solid answers:

Why does Labview create a .vi for each global variables?

Hello,
I wrote an Labview application which use several global variables (almost 30 variables). All the variables are of variable type "single process". For each of these variables, Labview creates a vi.
For example, for the variable "_TS.Measures.channes", Labview creates a vi named "TS_'_TS.Measures.channels'.vi". Which means, I have almost 30 "name of variable".vi files: this is confusing!
All my VI are inside library (.llb). When I try to put the VI of a global variable in a library, Labview can't find them anymore.
May be can somebody explain me, why LabVIEW does create these VI and how is it possible to put them in a library.
Cheers,
Risotto

Hi everybody,
Thank you for your answers, I get a lot of informations.
Yes, I use the new shared variables in LabVIEW8, which I am using like sort of global constants. Now I am understanding what guys are telling me all this about global variables in LabVIEW7.1. Sorry, I forgot to say I was using LabvVIEW8.
I will have a look on the tutorial too.
But yet one point about the library collecting all the shared variables in the windows explorer and in the project explorer: When I create a shared variable in my LabVIEW project - for example "test1" as double/single process - the variable doesn't appear in my file directory, but it appears in the project explorer in a library (.lvlib).
When I drag/paste my shared variable on the block diagramm of my VI, then a file "Math_test1.vi" appears in my file directory. There is no extra .llb created to contain my shared variable vi.
If I drag/paste the file "Math_test1.vi" in the Math.llb (see picture), then the file is moved in the llb and disapeared from the directory.
If I created another shared variable "test2" as double/single process and put it on the VI, then LabVIEW creates2 files in the directory: "Math_test1.vi" and "Math_test2.vi". So that I get 2 vi for the "test1" variable now (one in the llb and one in the directory).
I use several library in the project explorer. But the library in the project explorer seems to create file with other extension (.lvlib) than the sdtandard LabVIEW library (.llb).
Cheers,
Risotto

Supplier Registration - Is it possible to push new created vendor in SRM?

Hi SRM / SUS experts,
We are defining Supplier Registration processes and had a question with regards to it. After getting supplier information through forms and questionnaire, let's say I approved it and then converted it to Vendor in SRM. Then, is it possible to push newly created vendor back to ECC? I see (database) icon to push vendors to ECC in monitor Business partners transaction, but it is disabled. I am thinking since I have not set up XI integration with ECC, the icon is disabled.
Will you please share your experience with this functionality?
If it can be pushed, then which account group will it take when it is created inECC and which views are created (General data views?)? Is it created under same number as SRM business partner?
Your inpur is highly appreciated.
Thanks,
Chandra

please refer to the following SAP help for more details on the Montior Business Partners --> and what can be done there
http://help.sap.com/saphelp_srm50/helpdata/en/e6/4b4b3c99c53c33e10000000a11405a/frameset.htm
--> you have to open the tree --> Business Partner Monitor..
and for the option --> to be enabled --> to transfer to backend -> it is looking for two flags
1) Xi should be active in your system
and please refer to the following code --> which decides wether the backend transfer should be enabled (or) disbaled...
technically i know where it happens

Is it possible to display only dynamically selected fields in the out put?

Is it possible to display only dynamically selected fields in the out put? i need to display set of columns in the selection criteria, but in the output i have display only input given fields. because i need to convert it into .csv file. So i have to display selected fields from internal table. In oracle they are using"execute immediate". is there any equivalent in SAP?
thanks in advance.

Hi Remya,
Are you talking about dynamic programming in ABAP ?
If yes, there are concepts like RTTS which facilitates it.
Yes, the select query also supports dynamic selection of fields. ( Please care about ( ) in dynamic sql ).
Do more research on Field Symbols and statements like ASSIGN COMPONENT OF.

Philip.

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.

Is it possible to change what is displayed in the GAL in Exchange 2013

We have always used [email protected] for our primary email addresses, and to facilitate this someone back in the days of Exchange 2003 decided it would be sensible to use the firstname.lastname
format for our alias. This means our primary email does not match our UPN. Now, we are moving to Exchange 2013 and want to use autodiscover we find we need to change this so primary email and UPN are the same while still retaining the original email
addresses. Easy enough change, powershell script to modify the alias, new address policy on the 2013 server and migrate your users, changes made for you.
However, this has caused some concern amongst the senior management because it changes what is displayed in the GAL, so instead of the friendly first.last name listed under alias and the just as friendly
[email protected] listed under email address it will now show the UPN as alias and
[email protected] for email.
I have now been asked to see if it is possible to modify the details displayed in the GAL, I know you could in previous versions of Exchange using things like EMC, but I don't see any way of doing this in 2013.
Is this possible, and if so how?

I'm using a PC to convert pagemaker files to PDF to send to the newspaper printer exactly as I have done for years. Suddenly Acrobat distiller will not let me create the pdf. Can anyone help me?@@

I did think about that and if I have to I will do that, however there are about 50 songs. I have closed and reopened iTunes several times and I am sure that I have the latest version. It fails right away but I can click on the cloud download icon and download the song that it failed on ... therefore it is not that song "or any one song" causing the issue. Any ideas?

I've created a fillable PDF document in XI Pro. I need to change the body of the document and create a new fillable PDF document. When I do that it won't let me create a new PDF. It keeps saying "no new fields recognized. What can I do to redo my document with the changes in the text, but no changes in the fillable fields?

You start with a source / authoring file for the "static" content (e.g., Name, Last:). Say this is an MS Word file.
You master the "static" content..
You keep this authoring file and have a backup of this file.
You output a PDF and use Acrobat to build and fine tune the "form" (form = the form fields, not the "static" content).
The authoring file and output PDF (with form fields) gives you "rev 00".
Now, you must change something in the "static" content.
Open the authoring file and save as to a new version (e.g., "wordfile_v00" becomes "wordfile_v01).
Output this to "pdffile_v01".
Use Acrobat to open the PDF form file "pdffile_v00". Save As to a new file name ("pdffile_v00update").
Using Acrobat XI Pro the click-path Tools - Pages - Replace lets you replace a page or pages of "pdffile_v00update" with a page or pages from "pdffile_v01".
This replaces the "static" PDF page content and does not affect the form fields on the page.
(you may have to adjust position of form fields)
Save "pdffile_v00update" to "pdffile_v01" to reflect the revised status of the PDF form file.
Be well...

How do I call a LabVIEW created DLL from within Microsoft Excel (VBA)?

Hi,
I'm trying to get Microsoft Excel 2003 to call a function stored in a dll that I created using LabVIEW 7.1. The function is very simple and is called "binary_file_to_ascii". Basically it just reads a LabVIEW created binary spreadsheet file and outputs the columns as float arrays.
The function arguments are as follows:
INPUT : String that contains the path to the binary spreadsheet file
OUTPUT : Number of rows in the spreadsheet
OUTPUT : Number of columns in the spreadsheet
OUTPUT : Float array containing the elements in column 1
OUTPUT : Float array containing the elements in column 2..
OUTPUT : Float array containing the elements in column 11
However, for some reason there is something wrong with my VBA code and/or the way I created the DLL in LabVIEW because Excel crashes when it loads my DLL.
What do I need to change in my VBA code or my LabVIEW DLL build settings to fix this?
I've attached to this post a ZIP file that contains all my code and a sample binary file.
Your help with this will be much appreciated. Thanks!
Richard
P.S. Here is the VBA code I'm using:
Private Declare Function binary_file_to_ascii Lib "C:\temp\binary_file_to_ascii\binary_to_ascii.dll" _
(ByVal binaryFile As String, ByVal nrows As Long, ByVal ncols As Long, ByVal column1 As Variant, _
ByVal column2 As Variant, ByVal column3 As Variant, _
ByVal column4 As Variant, ByVal column5 As Variant, _
ByVal column6 As Variant, ByVal column7 As Variant, _
ByVal column8 As Variant, ByVal column9 As Variant, _
ByVal column10 As Variant, ByVal column11 As Variant)
Private Sub load_binary_spectra()
Dim nrows, ncols As Long
Dim col1(), col2(), col3(), col4(), col5(), col6(), _
      col7(), col8(), col9(), col10(), col11() As Variant
Dim lRetVal As Long
Dim spectra_path As String
    spectra_path = "C:\temp\binary_file_to_ascii\sample_binary_file\sample_binary_file.dat"
    lRetVal = binary_file_to_ascii(spectra_path, nrows, ncols, _
              col1(), col2(), col3(), col4(), col5(), col6(), _
              col7(), col8(), col9(), col10(), col11())
    MsgBox (spectra_path)
End Sub

Hi,
I don't know anything about Visual Basic, but here's my guess.
When you load the DLL with this line of code
Private Declare Function binary_file_to_ascii Lib "C:\temp\binary_file_to_ascii\binary_to_ascii.dll" _
(ByVal binaryFile As String, ByVal nrows As Long, ByVal ncols As Long, ByVal column1 As Variant, _
You are defining how the parameters are sent. It seems that all are sent by value (ByVal), but in the DLL header, some of the function's
parameters are defined as pointers(see the function prototype below, look for asterisk(*))
void __stdcall binary_file_to_ascii(PStr binaryFile,
                                                long *numberOfRows,
                                                long *numberOfColumns,
                                                float column1[],
                                                float column2[],
                                                float column3[],
                                              float column4[],
                                                float column5[],
                                                float column6[],
                                                float column7[],
                                                float column8[],
                                                float column9[],
                                                float column10[],
                                                float column11[]);
Can you define in VBA that you want to use pointer instead? Maybe by using ByRef (as by reference).
Hope this helps.

Is it possible to let Labview create displays himself dynamically?
