Create console output from LabView

Hi all.
Is there any way of creating a console string output when calling a dll from LabView?
I have to call a C++ program from LabView and I'm using a dll. I need to debug this program, and I think that using "cout" is the fastest and simplest way.
Thanks in advance.

Francisco

No, there is no console output when calling a DLL. You could have your DLL simply write debug information to a log file.

Can I create a dll from labview with more that one function name

I know that when I create a dll from C and then call it in labview using the call library function node I can see the different functions on the configuration screen. Is there a way to create a dll in labview to have more than one function name? No matter how many functions happen in my VI it seems to build into a dll under the same function name requiring inputs for every function, can this be avoided somehow?
Thanks,
Dave

Each function corresponds to a separate VI. When creating the dll, on the Source Files tab of the app builder, click the Add Exported VI for each VI that you want. SubVIs of a main are not automatically exported and will not be available as separate function calls.

Writing console output from numerous classes to JTextArea?

I have written a GUI for several classs and I was wondering if it is possible to have the output from these classes written to something like a JTextArea or equivalent.
I know I could store the output (instead of System.out.print) and then setup a JTextArea and set the text equal to the stored output. I was hoping there was another way to do this that'd be more aesthetic.
Thanks in advance.

Create PDF output from Web Layout Report

Is there a way I can create a PDF output from a Web Layout Report? (NOT from a Paper Layout). The reason I ask because editing on the .jsp Web Layout is very easy and flexible while editing on the Payer Layout is very difficult. Thanks.

Hi Todd,
Please refer to this link:
paper layout & web layout
As for your second statement, it is a matter of opinion and I beg to differ that .... "Web Layout is very easy and flexible while editing on the Payer Layout is very difficult."

Synchronize waveform output from labview to bnc 2110

Hi,
I'm new to LabView and I would appreciate examples on how to output a waveform graph from LabView to a BNC2110.
Eventually we would need several graphs, both analog and digital outputting to a BNC2110 synchronized with a clock.
Thanks. Appreciate any help.
Grace

You can't output anything to a BNC 2110. The BNC 2110 is a dumb terminal block. You can however, output signals (not graphs which are visual elements) from a DAQ card that you control with LabVIEW. You would then connect the DAQ card to the BNC 2110. If you have an NI DAQ card, then there are a large number of example programs that show you how it could be used.

Create Billing Output from VA01

Hi everyone!
I wonder is it possible to create an invoice with billing output immediately?
I usually use create sales order VA01, create billing due list VF04, create billing output VF31;
I'd prefer to be able to key on an invocie and for it to create a billing document in my spool right away without having to wait on the overnight process or manually pushing it using VF04 & VF31.
Any ideas?
Many many thanks!!!
Ciara

Hi,
For this change to appear we have to go for some seetings.They are mentioned below.
1.Goto the T.Code "NACE".
Select the application as "V3(Billing)".
Click on "Output types".
Select your output type.
Click on "Details" or Press "CtrlShiftF2".
Maintain the value as "4(Send Immediately(when saving the application))" for the field "Despatch time".
Check the value for transmission meduim.Ithink it is "1(Print output)".
Save.
2.Goto the T.Code "VV31".
Enter your output type.
Press Enter.Select your valid condition table if multiple tables exists.
Enter.
Maintain the valid values.Select that maintained entry.
Click on "Communication".
Maintain the output device as "LOCL".
And also check the box "Print Immediately".
Save.
If you create the invoice by using VF01,then the out put will be triggered automatically.
Or Goto T.Code VA02/VA01.After entering al the values,Click on "Sales document" in th emenu bar and then click on "Billing".
Even in this case also output will be triggered automatically.
If you want,then you can reprocess this output by using the T.Code "VF01",by selecting the processing mode as "2".

Krishna.

Console app from labview VI

Hi,
I have a VI which I have turned into an EXE and it works fine (as a dialog-based app). I now want to use this EXE as a console app -- be able to give the input AND receive the resulting output on the command prompt. How can I do this?
I know how to pass in arguments to my EXE from command line. The problem is how do I output the result (bunch of strings) back to the command prompt?
One solution I guess is to build a DLL from my VI and then create a console app in VC++ calling this dll in it.
Any other ideas? examples?
TiA!
Khalid

Hi,
For the output...
Use GetStdHandle, kernel32 to get a handle, (handle GetStdHandle(long
param), use -11 for parameter);
Use WriteFile, kernel32 to write a string (long WriteFile(long handle, CStr
message, long length, long *written, long overlapped));
It actually works!
Regards,
Wiebe.

How can I programatically control the names of files output from Labview into .pdf format (ie with Adobe PDF Writer or Distiller)?

I would like to save some data forms for a standard test controlled with labview in a pdf format. Due to the large number of forms and test reports, I would like to have Labview automatically assign the .pdf file name based on test number already contained in the labview code. How can I do this.
Note: This question is very similar to:
"Labview and Adobe Acrobat output" posted by John Balone on 1/26/2000. The reponses offered good suggestions but it is not clear to me how to implement them.

This information is essential if you plan to use the Acrobat Distiller printer driver and any of the examples listed here:

Missing functionality if storing TDSM from LabVIEW

In DIAdem File Browser window is selected a file from DIAdem 11.0 Examples directory. File FFT_Expl_1 has icon with „tree pictogram“ and „tree pictogram“ can be expanded to see content of file (Time, Oscillation), bellow of File Browser is displayed many file properties. Anyway these properties are not displayed in DataPortal area?!? See picture 1.
Pict. 1
If I click on the file content in tree hiearchy channel Oscillation I can see properties for this channel and small graph with the signal preview. See picture 2.
Pict. 2
To make my own data I have used examples from LabVIEW 8.6. One of these is on the picture 3 TDMS - Express write data (time and frequency domain).vi.
Pict. 3
Every time I create TDMS data from LabVIEW 8.6 (it doesn’t matter which example I use) I see in DIAdem File Browser instead of tree icon the question mark icon?!? The question mark icon cannot be expanded by clicking on it?!? Also the amount of Shown properties is significantly lower in comparison with DIADem example files. Also no signal preview is displayed?!? How to proceed with LabVIEW and TDMS function to have possibilities of DIAdem example files?
Screenshots are in attached DOC file.
Please help

Hello bilik,
Thank you for the great description of your problem, the Word document with the screen shots really helps with the troubleshooting.
It looks to me as if you haven't indexed the directory where your TDMS files are stored. The "?" icon indicates that the file is not indexed. If a file is not indexed, only a subset of the properties are shown in the dialogs.
The easiest way to solve this issue is to index the directory that contains you data files (your directory icons are grey, they should be yellow). This can be done by going to the directory (or subdirectory) in the DIAdem NAVIGATOR window, and right clocking on the directory name. From the context menu, select the function "Add Search Area ..." - your directory will then be transferred to the Search Areas part of the NAVIGATOR and all the TDMS files will be indexed. At the point the files will show all the properties and the "?" will disappear.
Let me know if that helped,
Otmar

Creating a DLL in LabVIEW containing a function using pointer to pointer

Hi!
I´m facing the problem to create a DLL from LabVIEW containing the following C-function:
functionF(structS** arrayA) ,
where:
structS is a struct of various data-types (e.g. int)
arrayA is an C-array of structS
How can this be done? Any ideas?
Thank you in advance for your support

This cannot be done in LabVIEW. LV doesn't have the data type "Pointer" as C has.
The only workaround I can think of is to use an array of strings in LV and in the interface define the parameter as "by reference". In LV you have to typecast the wire with the string to a cluster withthe layout of structS.
As far as I know an array of strings is represented as an array of pointer to strings. This is because strings are variable in length and therefore LV uses this method storing the pointers to the strings in the array and not the elements as usual.
You have to read the document about memory and data types of LabVIEW. In elder versions this was in the LabVIEW Bookshelf but I haven't found it in short in the newer version.

How do you create a program in Labview that can be run as a Windows Service?

I would like to create a Labview program that can be run as a Windows service. I have read the following Knowlegebase articles and have done what they say.
Creating a Windows NT Service Using LabVIEW http://www.ni.com/white-paper/3185/en
Running a LabVIEW Application as a Windows NT/2000/XP/Server 2008/7 User-Defined Service http://digital.ni.com/public.nsf/allkb/21BA0F671A63A60386256CB4004DF99B
When trying to start the service I get an error that says the program didn't respond to the start in a timely manner. I also set the "run when opened" parameter in the VI. I am programming in Labivew 2010, proffesional version. The server is running Windows Server 2008. Can anyone help? Is the ini file important in Windows Server 2008?

I haven't looked through all those links. But I have created Windows Services from LabVIEW executables way back when WinXP came on the market.
The problem with services is that they have no UI. So you can't really see what is going on. Your EXE might be failing or hanging due to some kind of error (most liklely a security/permissions error), but you can't see the error. So my advice is to either:
1. Have your EXE write lots of info to a log file. Write info that log every step in the application. If an error ocurrs, have it write the error info to the log file. That is a very useful debugging tool.
2. Use VI Server functions to monitor the service to see what is going on.

Create dll from labview

Hi all:
I am using labview 8.5 , i want to create dll for spacific vi , to use its output in another program like C++,
can any one help me to learn the steps to create dll from labview
thanks

You need the application builder (which is part of the professional distro).
In general you should every VI that you want as a function set to 'top-level'
If you right click on the builds in your project you have an option to build a DLL (if you have the application builder), from there on the help is available.

How to create a dll from vi in Labview 7.0 ?

Hello,
I want to create a dll from a vi in Labview 7.0.
I've found the url: http://zone.ni.com/devzone/conceptd.nsf/webmain/003A3E6A5E9CCCEC8625691F0072B2C5
explaining how to create DLLs from LabVIEW in Labview 6.0i but this method is not available in my Labview 7.0.
How is it possible to create a dll from a vi or from vi's (stored in llb-files) ?
With thanks,
best regards,
Geert

You can only create DLLs and Standalone Applications if you have LabVIEW professional or higher.
If you only have LabVIEW Base of Full, you need to purchase the Application builder seperately.
(Check under "Deployment tools" in the LabVIEW comparison matrix. What level do you have?)
