Problem with building a dll in labview

Hello,
I want to be able to run a LabView vi from Java and found that the best way to do this is to create a DLL in LabView and then call it in Java using JNI. I did a dummy program in LabView to test, but the problem is that the instructions I found don't seem to exist! For example, one tutorial I was following said to: "Open a new VI and select Tools»Build Application or Shared Library (DLL).". But I don't have that under tools, just Build Application (EXE) from vi, which gives a project file. In another place it said to "Expand My Computer. Right-click Build Specifications and select New»Shared Library from the shortcut menu to display the Shared Library Properties dialog box" but I have no idea what that means.
I have the LabView 2009 trial version, could that possibly be making a difference? If not, what am I doing wrong? Or is there a better way to run a LabView program from Java?
Thanks a lot!
Hugh

Actually, the second one is from LabView help. I tried looking up Application Builder like you said but again it begins with the instructions "Expand My Computer. Right-click Build Specifications and select New»Application from the shortcut menu to display the Application Properties dialog box" and I have no idea what this means What do they mean by My Computer? And Build Specifications? I don't have any of that... I'm sorry but I'm new to all of this, I've never worked with DLLs before in any language, and all I want to do is run my LabView program when I press a button on my Java interface!! If there is a better way to do it, that would be great!
Thanks at any rate,
Hugh

Problem with building a dll

Hello! I am trying to learn how to build a DLL with Labview. I have made a simple VI that concatenates 2 numbers into an array. Then a indexes that array and puts that number to an indicator. This works fine.
But, if I instead invokes the sub-vi Mean to calculate the mean of the array nothing happens. No results at all comes out from the dll.
WHY?
I have seen that the sub-vi Mean is a DLL, do I have to add that in the builder?

Hello Thomas!
Could you send your program for further investigations?
cheers

How to remove the "int len" of my return string on the DLLS header when building a DLL on LabVIEW 8.5

Hi all.
I'm building a DLL on LabVIEW and I choose a string as an output on the terminals connectors.
But LabVIEW creates another output, the lenght of the return string.
This is a problem because I have other DLLs and I need them to be compatible.
How do I remove this length from the header? What is the difference between Pascal String and C string and String Handle Pointer?
String Handle Pointer removes the length from the header but I don't know the difference between this data types.
Thanks in advance for the help.

C string pointer is a pointer to a memory location whose string information is terminated by a 0 byte. Pascal String Pointer is a pointer to a memory location where the first byte specifies the number of bytes to follow. This obviously allows only for strings up to 255 character length.
LabVIEW String Handle is a pointer to a pointer to a memory location where the first 4 bytes are an int32 value indicating the number of characters to follow. You can read such a String handle in a function without many problems, but you can only create, resize and delete such a handle by using LabVIEW memory manager functions. So this makes only sense if the caller of such a DLL is LabVIEW too as another caller would have to go through several hoops and tricks in order to gain access to the correct LabVIEW kernel that could provide the memory manager functions to deal with such handles.
Last but not least output strings whose allocated length is not passed to the funciton as additional parameter are a huge secerity risk (talk about buffer overrun errors). LabVIEW DLL Builder does not support the creation of DLLs with output string (or array parameters) without the explicit passing of an additional parameter telling the DLL function how large the allocated size is (so that the DLL function can make sure to never write over the end of the buffer).
The additional length parameter only disappears for String Handles because LabVIEW will simply resize them to whatever length is necessary and that is also the reason why those handles need to be allocated by the same memory manager instance that is also going to execute the DLL function.
Resizing of memory pointers is non-standardized and in normal circumstances not suited for passed function parameters at all.

Build a DLL in LabVIEW & Use the DLL in LabVIEW

I am trying to build a DLL for the simple vi with LabVIEW and want to use the DLL in LabVIEW. is it impossible?
I wrote a vi and it have 2 terminals. one is the input for numeric dbl data type and one another is the output for numeric dbl 1D array data type.
It was built with the Application builder for LabVIEW 8.0 and DLL was created successfully.
I want to use this DLL in new vi with LabVIEW.
Call library function used. I wrote a new vi to use that DLL.
In config dialog I config each parameter for dll and connected terminals. but it doesn't work
pleas refer to the attatched file and let me know what I missed.

At first I kept scratching my head wondering why someone would want to do this. Create a DLL in LabVIEW to call it from LabVIEW. Seems redundant. But, perhaps it's an exercise or perhaps it's for testing the DLL...
In any event, calling the DLL worked for me in 8.2. How are you configuring your Call LIbrary Function node? I have it set up as follows:
return type: void
iteration: Numeric, Signed 32-bit Integer, pass by value
array1D2: array type, Signed 32-bit Integer, 1 dimension, "Array Data Pointer" format
len: Numeric, Signed 32-bit Integer, pass by value
Then I called the DLL like this:

Problems with a waking up a labview executable after computer hibernation?

I am just wondering if anyone has had any problems with waking up a labview executable after hibernating a computer. The executable was running before the computer was hibernated and it seems to have frozen not crashed after the computer was woken up. I am using Windows 7 and Labview 2009.
Thanks for your time.

What is the application doing? (if that even matters)
If it were performing a data-acquisition hardward process then that might matter..
I haven't experienced this problem.

Problems with building blueprints catalog

Hi,
I've got some problems building bp-catalog v 0.8 on a windows 7 machine, GlassFish 3.0.1.
I've properly changed build.properties file and executed "ant setup" but when I issues the "ant run" command, the compiler can't find packages (JSF packages mainly).
Why it cannot find jars? The ant script should include glassfish jee jars into classpath...right?
I've got the same problem with Petstore but since it's a netbeans ready project, I easily imported it and configured the runtime to GlassFish, and this solved the problem.
With the bp catalog, it could be pretty handy to build and deploy all the projects, without to import one by one in netbeans and manually solve the missing references problems.
Many thanks in advance:

Problem with build file

Hi All,
I have an unique problem.
I have a build file which is runnin successfully on a local but not on the server.The error is class not found, so definitely problem with classpath.
but acc. to my knowledge the build file is setting up the classpath in the file only, so its independent of my classpath settings in the system.
Please help
the snippet fo build file
<project
    name = "SqlcSamples"
    default = "bundle"
    basedir = ".">
    <property file = "build-sqlc-eu.properties"/>
    <taskdef name = "sqlc" classname = "com.pavelvlasov.sqlc.StatementCompilerTask">

        </classpath>
    </taskdef>

its saying 'com.pavelvlasov.sqlc.StatementCompilerTask' class not able to found

Best is to use the ant documentation; I often need it.
ant without options will use build.xml, as "makefile".
In the build.xml you define your default target.

Problem with building array inside a case statement

I have a problem with my build array.
Iam trying to construct a build array when ever I see a new element in my parent array during run time.
Using shift registers, search array and If- case structure, inside a while loop. Iam implementing this logic (I dont want to use Event structure).
Iam able to achieve most part of it, but have a problem with the first element. Except the first element of my parrent array, every thing is appending in to the build array. Can any one look at my vi and suggest me what Iam doing wrong here.
Thank you

I think you need to replace the tunnels (carrying the array) in the for loop with a shift register.

Problem with building web service control

Hi i am using a web service control for invoking a web service. the application builds correctly from workshop and i am able to talk to web service. However, when i exported the ant build file from workshop and tried to build the application from prompt using ant, it gives me follwoing wrror -
[wlwBuild] [Build] Errors found in D:\crmwork\weboss\esb\ESBPrj\com\covad\esb\controls\BillingServiceSBControl.jcx:

[wlwBuild] [Build] Error at line 9 column 18:
Has anybody encountered this error? What could be the problem cause the workshop build works fine.

I solved the problem :-)
it happened due to JAVA_HOME env var. It has to point to jdk that comes along with wl812. mine was pointing to sun jdk 1.4.2. However, this is a bug, because, for wlwlbuild task , i was setting the proper bea java home, still it was failing due to system java_home var. And i did not face this problem with WL813. After facing lot of issues with 812, now i feel, 812 is not a stable production version.
Anyways, now the prob;em is solved.

Problems with build in wifi card in DV6-2190us.

Hi am trying to see if someone can help me out with a problem am having with my WIFI and also LAN on my laptop.
The problems am having is with connectivity and speed on WIFI and also problems connecting to a network with a Ethernet cable.
The problem am having with my wifi is when trying to connect to a network it takes me about 5 to 10 minutes just to try to connect to the network and once connected it will continue to say unidentified network and it will take 5 to 10 minutes to connect to the internet. Once connected to the network and the internet the connection will start fast and slow down to a crawl even do am 10 to 20 feet away from the wireless router and I have full bars. After the connection slows down I will get disconnected from the network and it will take me 10 to 20 minutes to get back on it.
Also when I try to connect to the network using a Ethernet cable I will get connected but if I unplug the cable and try to connected again I won't be able to connect to the network or the internet and I would have to restart the laptop with the cable plugged in.
All of the drivers on the laptop are up to date and also windows is up to date I really don't know what's going on.
I have formatted and installed Widows 7 done all of the updates I have also updated all of the drivers for the laptop but the problem continues to come up.
After talking to some of my IT friends we removed the build in wifi card from the inside of the laptop and changed it with a wifi card of a same model laptop to rule out problems with the card, but the problem continues to happen with the new card installed on the laptop. The card that came out of the laptop with the wifi problems was installed to the second laptop and the wifi problems came up but after installing the original wifi card the problems went away.
The thing that trying to figure out is why the card that came out of the working laptop won't work correctly on the laptop that's having problem with.
If anyone has any ideas on what maybe causing the problems please reply to this post I really need to have this problem fix before I start taking online classes.
Thank you for taking the time to read this post.

You are posting on an iMac forum. I'd recommend posting a MBA forum, however I think you best bet is taking it into your local Apple store or AASP to determine if the Wi-Fi adapter is damaged and if it is then checking to see what options you have.

Problem with building conditional display items

Dear All,
Please help as I am using APEX for the first time.
This my requirement during form dispaly in tabular format. There is one display item QA_TIER(not a database item). This item value is computed based on the condition below.
I created a display item with :
Source Used : Always, replacing any existing value in the session state
Source Type: PL/SQL Expression or Function
Source value or expression:
begin
if 2<=(select decode(&Leg_Req,'Y',1,0)+decode(&maj_funct_chg,'Y',1,0)+
decode(&maj_tech_chg,'Y',1,0)+decode(&maj_ui_chg,'Y',1,0)+
decode(&maj_def_met,'Y',1,0) from dual) then
if &Customer_Priority = 1 then
return 1;
else
return &Customer_Priority-1;
end if;
ELSE return &Customer_Priority; end if;
end;
Note : All reference with '&' are the actual field name.
When running the page i get the following error message:
ORA-06550: line 2, column 23: PLS-00103: Encountered the symbol "&" when expecting one of the following: ( ) - + case mod new not null others select table avg count current exists max m ORA-06550: line 2, column 48: PLS-00103: Encountered the symbol "&" when expecting one of the following: ( ) - + case mod new not null others table avg count
     Error      ERR-1020 Error in PLSQL item processing (function).
Can anybody help me with building the display item with conditions as show above.
Thanks in advance

hi thanks for the help.
I tried this time source type SQL Query:
with both suggestions
1.
select (case when
2<=to_number((select decode(v(Leg_Req),'Y',1,0)+decode(v(maj_funct_chg),'Y',1,0)+
decode(v(maj_tech_chg),'Y',1,0)+decode(v(maj_ui_chg),'Y',1,0)+
decode(v(maj_def_met),'Y',1,0) from dual)) then
(select decode(v(Customer_Priority),1,1,v(Customer_Priority)-1) from dual)
ELSE v(Customer_Priority) end) from dual
Result:
ORA-00904: "CUSTOMER_PRIORITY": invalid identifier
     Error      ERR-1019 Error computing item default value: page=2 name=QA_TIER.
2.
select (case when
2<=to_number((select decode(:Leg_Req,'Y',1,0)+decode(:maj_funct_chg,'Y',1,0)+
decode(:maj_tech_chg,'Y',1,0)+decode(:maj_ui_chg,'Y',1,0)+
decode(:maj_def_met,'Y',1,0) from dual)) then

Result:
ORA-00932: inconsistent datatypes: expected NUMBER got CHAR
     Error      ERR-1019 Error computing item default value: page=2 name=QA_TIER.
Both didn't work.

How to build a dll for labview pda, which uses the intel ipp primitives in it

Hi all,
For my application, I need to call a c dll from Labview PDA, and in the c function i need to use intel IPP function. When i call my dll, i get an error saying the ippfunction i use, say "ippsCopy_16s missing c or vi file". Can someone tell me what I might be doing wrong?

Hi Vani,
When using a DLL in a PDA there are some special considerations you have to take. Please take a look at the following knowledgebase describing the process.

Problem with running a program under Labview 8.6

Hello,
I am writing you this to ask for your technical support to fix the problem I am facing at our Lab at University of California, Irvine.
Ms. Vanessa Trujillo has kindly come to our lab a couple of times and tried different things to resolve the issue, but unfortunately the issue is not resolved yet. Here is a summary of the problem:
We used to use Labview 6.1 for our fatigue testing and data acquisition.
Our
program worked just fine under the 6.1 version We recently upgraded our software to Labview 8.6. We have also purchased a new computer that has higher capacity than what your website requires for Labview 8.6. The new computer has Windows Vista We transferred our old program/subprograms from the old computer under Labview
6.1 to the new computer with labview 8.6. However our program that worked fine with the 6.1 version is not working with the updated version (ver 8.6).
There
are 6 errors in the error list. It appears there are six files of my program missing under the new version, even though we transferred all files.
The software searches for those files but can't find them.
        For example one the box pops up indicates:
        loading:
                    <vlib>:\Daq\lvdaq.dll
        searching:
                    C:\Program Files\National Instrument\LabVIEW 8.6\instr.lib\Agilent34401\public\utility
        I get several message like this. I have to cancel/ignore them all to be able to open the program.
When we go to VI's under Measurement I/O there is nothing (empty).
We use a PCI-MIO-16XE-50 for our data acquisition During Labview installation on the new computer, I was asked if I wanted to install the device drivers. I had two options, "Now" or "Later", I picked Now but I didn't have the DVD's/CD's for the device drivers. Therefore I had to select later to complete my software installation Later after Labview 8.6 installation, we installed the device drivers (traditional Ni DAQ and Ni DAQmx) from the two old CD's we had in our lab from a couple of years ago (the CD's were Ni DAQ 7). after installation, the PCI board on the computer was recognized by the device driver. However we still could not run our program under the new version of Labview (same situation and the same messages) I called 1-866-275-6964 on 9/2/08 and talked to Grant (service number:
1228841). He recommended that I download and install the updated version of device drivers.
Since I didn't have the DVD/CD for updated device drivers, I contacted Vanessa Trujillo. She gave me the DVD for the updated Ni DAQ (Traditional and mx).
But
when I tried to install the updated device drivers I got a message something like "some unsupported filed have been detected,..." so the updated device
drivers were not installed. It should be noted that up to here we still had the Ni DAQ (traditional and mx) installed on the computer from our old CD's (Ni DAQ 7).
Vanessa and I talked to Tom at the technical support department. He recommended that we download and install the Beta xx version for Ni DAQ since we were using Windows Vista. Mike put the Beta software on the Ni website/outgoing so I could download and install it. He asked me to uninstall the traditional Ni DAQ that we had on our computer from the older CD's. He
asked me not to un-install the Ni DAQmx (that we had installed from the old
CD). I was able to download the Beta software, however I could not install it since I got a similar message that some unsupported files were detected.
Right now we don't have any version of traditional Ni DAQ installed on the
computer but the NI DAQmx (from old Ni DAQ 7) is still installed on the computer. Vanessa let me borrow her new Ni DAQ DVD but as I explained I am not able to install the device drivers.
Vanessa - Did I miss anything?
Please advise. My cell number is 619-778-2033. I will be at our lab at UC,
Irvine at 2:00pm (CA/Pacific time). Please call if you have any questions.
Thank you

To me, it looks like you are missing some of the drivers and subVI's used in your program.
Whatever device you are using to measure fatigue or any other device probably came with a driver.
You need all of these drivers installed on this new computer.
Also, any subVI's and libraries you use in the program must also be installed on the new computer.
Whenever you get a message that says you are missing some component (the ones that you said you press 'ignore'),
see if you can find that library or subVI on the older computer. If so, save it to something so you can transfer them to the new computer.
