Looking for lab view example

My application consists of collecting data from a bank of sensors as pressures and tempratures vary. I would like to run a lab view VI that tests the sensors, varies the environment and keeps track of all results, sorting them into good and bad. Each sensor needs to be tested in different pressures, then the temprature increases and the pressure test begins again. If there is a lab view example that might be able to get me started, I really need to find it. Thanks for any and all help.

There are a number of examples that ship with LabVIEW and their usefulness will depend on information not specified in your questions - such as what version of LabVIEW you have, what type of DAQ card(s) you have, and if you are using any SCXI hardware. If you open LabVIEW and go to Help >> Find Examples, you can search through a number of different examples.
For the application it sounds like a good place to start would be with an Acquire to Spreadsheet type of file that reads, graphs, and logs data. From there, depending on what you mean my using the card to vary the environment, you can find other examples of AO and DIO to perform these type of functions. These examples will give you a good starting place as to how a LabVIEW program works and the general flow
that you will need to follow.
Also, depending on your other needs, you might considering looking into examples with triggering to enable you to control when your program starts.

Looking for a 'view link target source' context menu item

I'm looking for a 'view link target source' context menu item.
I often open listings of servers' directories; they can include direct links to code files (*.py , *.pl, etc). When I click them directly, I'm asked to open them with an external editor which is not what I want to do; I want to view those files source inside of Firefox. I currently have to
# right-click those links,
# copy link location,
# type "view-source:" in the Location bar,
# paste the copied URL,
# click Go.
This gets time-consuming with the large amount of URLs I need to open.
It's not a native feature for Firefox and a search at [http://addons.mozilla.org AMO] didn't come up with anything useful, for me at least.

Hello,
particularly, I performed the following steps:
1. I created a SC in the local repository, which matches the SC of the track.
2. I moved the exisiting DCs to the SC created in step 1.
3. Now, I created new DCs in the SC in the track.
4. I deleted all .project files from the local DCs.
5. I copied all source files from the local DCs to the new track DCs.
6. I checked-in these changes to the track.
Kind regards

How to develop simple time based ramp driver for lab view VI

how do I develop simple time based ramp driver for lab view VI

Here it is converted to LabVIEW 2010. However it is missing the AO and AI read and write vis since I don't have that package.

Looking for simple search example using SELECT

Can anyone link me to an example of how to create a basic search page where the search criteria is selected in a drop-down list (<SELECT> in HTML)?
Here's where I'm coming from so you have a better idea of what I'm trying to do. I've created a search page by creating a method in my App Module java class using setWhereClause(), then dropped my view onto my web page as a read-only table, and finally dropped the method and parameter as a command button and input text field, respectively. This works fine, but I'd like to replace the input text field with a select box so that the users will not have to type in their search criteria. I'd like to populate the drop-down with data from a table, which will then be sent as the argument for the method.
I can create a ViewObject that contains the data I need, but I'm not sure where to go from there. I don't know how to create the drop-down list or connect the command button to the list. (Ultimately, I'd like to have the search text submitted when the drop-down changes, but I'll settle for pressing the button for now). I've fooled with using the LOV component, but without any luck.
Step-by-step would be great, but if you can point me to an example, some documentation, etc., that would be great too.
Thanks,
Andy

Excellent - Thanks for the link to the sample code page. I thought I had seen all the tutorials, etc. but for some reason never came across this page. The example you cited looks like it's just what I'm looking for.

Best type of NOx Analyze for Lab View.

My company is looking to buy a NOx Analyzer. What type of Analyzer would be best to use with Lab View.
It need to read CO, CO2, NO, NO2, and NOx.
It would also help to get an idea on the set up also.

Measure is an add-on for Excel and not a board for generic questions. You should repost to someplace more appropriate (i.e. LabVIEW or Instrument Control).

Looking for Simple JSTL Example

The distribution contains a "standard.jar" file and a "jstl.jar" file (among other things). The "standard.jar" file is included in my WAR (see above) and I have copied the "jstl.jar" file to:

Error: Attribute: items is not a valid attribute nameThanks (for reading),
Avi.

Thanks Qiang.
Yes, when I copy file "index.jsp" to directory "%J2EE_HOME%\default-web-app\testJstl.jsp" it works.
I use the following URL:
http://localhost:8888/testJstl.jspAnd this is the output I get:
[Format modified to be more suitable to post on this forum.]
Simplest JSTL
CONNECTION = [Ljava.lang.String;@7348e

ACCEPT-ENCODING = [Ljava.lang.String;@10a8143
ACCEPT = [Ljava.lang.String;@ac8360 HOST = [Ljava.lang.String;@1e534cb
[/pre]
But I guess, since the JSTL related JAR files are part of the default Web application, there is no reason it shouldn't work.
That's why you said:
Let us do a sanity test first.So now what?
(And, by the way, thanks for your help.)
Cheers,
Avi.

Application builder for Lab View 8.6.1 , 2009 SP1 and 2010 SP1

All 3 Versions seem to have huge flaws. With 8.6.1 When trying to build and application I get a duplicate name error and the application won't work. With 2009 SP1 I get Error 1003 broken VI when I have no broken VI's. Again Application won't work! With 2010 SP1 After the application is built for some reason lab view can no longer find the Excel sub VI's no matter how I place them in the build. And again application doesn't work. With all 3 versions the Vi's and over all programs work perfectly in the development environment. The application builder seems extremely flawed.
I would currently like assistance with 2009 SP1 problem the Error 1003 broken VI. I have reinstalled and rebooted my machine several times , tried including as much as possible in the build and still get the error about a broken VI. That works perfectly in the development environment. Please HELP?
Thank You

Looking for NIDAQ Functions/Examples for 'Analog I/O DMA' and 'Digital I/O DMA'. (I am using 6024,6503 boards and VC++ in my project)

I am using 6024,6503 boards. I need to implement AnalogInputDMA /AnalogOutputDMA,DigitalInputDMA and DigitalOutputDMA blocks for another software. Why there are no NIDAQ functions used with 'DMA' ?

Alan;
The NI-DAQ doesn;t have any functions to specifically access the DMA transfers, because that is done automatically for you. Once you set the data transfer to use the DMA channels, all the rest is handled by the driver.
Once you set up an Analog input task, and select the data transfer to use the DMA channels, you won't have access to the DMA channels but to the datapoints after the transfer.
Regarding the digital side of the application, I think that what you are looking for is a pattern input/output type of application, that will use DMAs for data transfer.
The 6503 doesn't offer that functionality. To accomplish that application, you will need one of the board of the 653x family.
Hope this helps.

Looking for lab zip

I am trying out Elipse package with Weblogic Server 10.3.6 (this is the version we have at work). I am working through a Web services lab. It refers to OEPE11gLabs.zip file containing assets required for lab excercises. I tried to search for it on OTN but get the current version. Is there an archive place where I can download this particular file. If someone have it, I will appreciate if they can send it to me.

Looking for a simple example of the Minimax algorithm in java

Hey everyone,
I'm currently working on a Gameboy emulator program as a pet project, and for one of the game's I'd like for the enemy AI to use the Minimax algorithm, but I don't have any experience with it (or recursion in general, for that matter). Could anyone maybe post a simple example of how this algorithm works?

WTF? I'm sure you can find plenty of examples on google. It's on you to take the time to go through them, study them, and, if you still don't understand something, post a clear, concrete question that indicates what you read and what you didn't understand about it.
As is, you're essentially treating folks here as your research flunkies and saying, "Give me an example that's better than all the ones already easily available to me. Read my mind to know why I didn't like them."

Looking for a simple example of how to query all the accounts

I'm new to the web service model in oracle crm and have been trying to just get a list of the accounts in the system. I generated a .cs class from the account wsdl and added it to my asp.net project. I'm able to get a handle on the account class but not sure the right syntax to make a call out.. As a fyi - i also have been able to login thru the service and obtain a session id.. so I'm that far..
Are they any existing code examples on how to query this? This is what I have so far but i throws an exception -
Account act = new Account();
act.Url = "https://"+dbcon.serverName+"/Services/Integration;jsessionid="+ sID;
AccountWS_AccountQueryPage_Input qbe = new AccountWS_AccountQueryPage_Input();
AccountWS_AccountQueryPage_Output qRet;
qbe.ListOfAccount = new Account1[1];
qbe.ListOfAccount[0] = new Account1();
qbe.PageSize = "20";
qbe.StartRowNum = "0";
qbe.ListOfAccount[0].AccountId = "";
qbe.ListOfAccount[0].Description = "";
//act.CookieContainer = .... is this line needed?
qRet = act.AccountQueryPage(qbe);
return qRet.ToString();
Thanks in advance for your help - Todd
Edited by: user11139473 on May 6, 2009 6:33 PM

Hi,
I am doing the same thing but I am not sure what is Account1 in your case. Can you show me the implementation of Account1 class?
Account act = new Account();
act.Url = "https://"dbcon.serverName"/Services/Integration;jsessionid="+ sID;
AccountWS_AccountQueryPage_Input qbe = new AccountWS_AccountQueryPage_Input();
AccountWS_AccountQueryPage_Output qRet;
qbe.ListOfAccount = new Account1[1]; <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< qbe.ListOfAccount = new ListOfAccountQuery();
qbe.ListOfAccount[0] = new Account1(); <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
qbe.PageSize = "20";
qbe.StartRowNum = "0";
qbe.ListOfAccount[0].AccountId = ""; <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
qbe.ListOfAccount[0].Description = ""; <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
//act.CookieContainer = .... is this line needed?
qRet = act.AccountQueryPage(qbe);
return qRet.ToString();
On the right is my line of code. The ListOfAccount member of AccountQueryPage_Input has datatype ListOfAccountQuery. In my case, a NULL is returned after the call.
Did you code work in the end?
Thanks
