In search of Projects based on Lab view.

Hi,
Iam Chaitanya, pursuing M.tech.. Iam using Lab VIEW,it is a good platform to work in realistic so I interested to do Lab VIEW projects. Can you please suggest projects based on Real-time applications or electronics.

Hi Chaitanya,
In real time application you can go for the projects like dataloggers which having communications. Here all the operations on datalogger can be done using labview. You can plot the graphs, show the RTC, download and process flash & eeprom memory and so on.
Or you can go for TCP like projects where some equipments are sending data using TCP and you are reading that data using TCP tools in labview and write to database,excel and plot it later.
Its all depends on you what you want.
Thanks
Kudos are always welcome if you got solution to some extent.
I need my difficulties because they are necessary to enjoy my success.

I need any IN LAB View FPGA Engineer,I'm tired of searching

Dear
I have work on vhdl language for more than 2 year on xilinx FPGA using xilinx ISE
I now work on labview FPGA due to its fast programming
I have main problem with LABVIEW FPGA and not solved until know which it as follow
when I need to build system in FPGA in xilinx ISE their a single clock and depend on this clock I will synchroniz the adder and multiplier and other elements using vhdl code so depend on my code this clock will have maximum frequency value and during simulation their is an single clock I can see the change.
But when I work on LAB VIEW FPGA no single clock appear and many clock source appear
for example
in compilation result you can see two clock
And in xlinx log you can see two clock
And from this http://www.ni.com/white-paper/12942/en
you can see three source
please expain to us what is happen !!!!

I nead to find some Lab View driveres for some instruments

Hello to you all
I need to find Lab View drivers for some instruments,I tried to look for them in the ni site and hp site and in every place I could think of but with no luck,
Does anyone know were can I find more Lab View drivers?
The instruments List is add as a word file
hoping to hear from you all soon

The instruments List .doc ‏23 KB

Some of these instruments do have drivers or ones for very similar instruments. They are the 8920,4416,8657,8901,8560,TDS540. I haven't gone to any of the vendors sites to see if there were any more you might have missed. You should also know that drivers labeled as 'plug and play' but not LabVIEW, can be converted to a LabVIEW driver.
If your search still comes up short, you have a few options. At http://www.ni.com/devzone/idnet/default.htm you can make a request for a driver. NI does drivers based on demand and there is no guarantee when or if they will develop one. You can develop them yourself. The above page has links that will help you with this. Developing a driver is not an especially difficult task. You can use the Instrument I/O Assistant or just regular VISA Read/Write to control the instrument. You can hire someone to write the drivers for you. NI has the Alliance Program at http://www.ni.com/alliance/. Some members specialize in driver development. You can choose one of them or someone local.

How to configure a shell and tube heat exchanger with Lab VIew to get data

HiI
In our undergraduate chemical engineering labboratory we want to configure our shell and tube heat exchanger with a DAq and Lab VIEW to get information about the temperaure (of the cold fluid stream being heated), the pressure (of the steam on the shell side of the heat exchanger) and the flowrate (of the water being heated).
Can anyone suggest thermocouples, pressure transducers and flowmeters to fit between the heat exchanger and the DAq?
P.S. the heat exchanger is already fitted with thermometers, a pressure gauge and a rotameter but we don't know how to connect these hardware to the DAq
Solved!
Go to Solution.

It sounds like you have enough information to pick out appropriate sensors, you just need to do the research. I would start looking through the Omega catalog, or give them a call - they're usually helpful. I can't take the time to spec out parts for you - that would be a lot of time spent on someone else's project. Most pressure sensors put out either a 4-20mA or 0-5V signal, either of which you can read through an analog input on a DAQ; measuring a 4-20mA signal requires a resistor to convert to voltage. Most of the NI DAQ boards can read a thermocouple on an analog input, but make sure that your hardware does support reading thermocouples. For accurate readings, use a device that has built-in cold junction compensation - for example, the SCB-68 connector block - and for the most accurate readings, get a board specifically designed for temperature measurement.
For the flow measurement, a standard, simple solution is an orifice plate. You put a differential pressure transducer across it, look up the appropriate equations, and use them to calculate the flow rate given the density of the fluid (which you'll be able to calculate from the pressure and temperature, since steam tables are widely available). There are other differential pressure devices available as well - at a previous job we used a V-Cone from McCrometer. If you call them they'll spec one for you - but get an approximate cost first to make sure it's within your budget.

How to create ADF UI based on polymorphic view objects

Hi,
I'm using JDeveloper build JDEVADF_11.1.1.3.PS2_GENERIC_100408.2356.5660. I created a simple application based on Steve's example #10 [url http://blogs.oracle.com/smuenchadf/examples/]ViewRow and EntityObject Polymorphism.
I added a men-only attribute "Age" to the "Men" VO and filled it with an arbitrary value in MenRowImpl.java:
public String getAge() {
return (String) "45";//getAttributeInternal(AGE);
}Running the TestModule works perfectly - a row of type "Men" displays the "Age" attribute whereas a row of type "Women" doesn't.
Afterwards, I setup an ADF ViewController Project and created a JSPX with a read-only form based on the "People" datacontrol with navigation buttons. Running that page always shows the same set of attributes independent of the row type. That's expected behaviour because the binding is defined at design time.
So my question is: can I somehow achieve the same behaviour for polymorphic VOs as the business component tester shows?
Kind regards,
Markus

Andrejus' example shows how to calculate different values for the same attribute based on overridden view objects. That's not exactly what I'm looking for. I need to display a (at least partly) different set of attributes that changes while the user scrolls through the records of the result set.

Is it possible to delete data from a block based on a view?

I have a data block based on a view. I have set the delete allowed property to 'yes' using the object navigator, have set the database permission to allow delete, done a search through all the code to see where the delete_allowed property on the block may be reset in some trigger yet cannot delete records from the block.
Any ideas?

There are at least two/three ways to do this...
Put an on-delete trigger on the block of the view with code something like this...
delete from mytable where mytable_id = :myblock.mytable_id;
...or...
dont do the above and add an instead of trigger to the view in the database. The instead of trigger intercepts the delete statement that would fail and executes code that you write in the trigger to go delete in mytable "instead of" the view.
... or...
if you want to base a block on a procedure.. See this thread... Notice the metalink id in the thread..

Thanks,

What I suggest is go into EM and undeploy this composite and all versions. (Only if you don't want the existing ones). Then redeploy your process. This will avoid the version conflict and create a new version. 1.0. Then the next time you try and deploy you need to either specify a new version or check the box to say the version can be over written.
cheers

Program associated with the creation of a virtual instrument of Lab View. Please help me

I have a question with program associated with the creation of a virtual instrument of Lab View. 1.Create of virtual instrument based on the NI 9401 module fitted to the chassis NI Compaq DAQ (Ni-cDAQ-9172). Creating a virtual tool needed to implement the following counting impulses in impulse series, visualization of data through a digital indicator, comparing the number of impusite with pre-set value, that value can be assigned by the user. Indicator light when reaching in reaching the set number of pulses, the opportunity to reset the meter of a button on the front panel. Switch to digital output in reaching the set number. I hope someone can help me.

What is your question? You've described what the program is supposed to do, but it's not clear what you're asking about. Do you need help getting started? If so, have you gone through the LabVIEW tutorials? You and look over the material in the NI Developer Zone's Learning Center which provides links to other materials and other tutorials. You can also take the online courses for free. Have you looked through the many examples that ship with LabVIEW for data acquisition?

Versions of lab view

Hi:
Just a few days ago i put this message:
Hi:
Im trying, to find a way to search, a file stored in different subfolders of a main folder, and copy, i mean i have a VI which makes a folder everyday (the name istoday date, or yesterday date), and inside that folder is a serial1.txt log file, but yesterday (for axample) the same log file (serial1.txt) was generated, how can i search in lab view all of those serial1.txt files?? By putting just in the search field, the main folder name???
And I want to copy each of these serial1.txt, to different paths???
So in this days, i ve working and the file is ready, but this archive just search like this: main directory /2nd directory/ 3rd directory/Files.... I mean if the files is deeper in more subdirectorys, does not work well works for me.
Im working in lab view 8.5 but, when i tried to put the .exe file in the computers where i have to look for my files, sorprise!!! the computers have the version 7 express or somethig like that so i cant use my file. IT Is possible change the version of my file to version 7?????

I don't know if you are still asking the same question in this thread or not. If you are, don't start a new thread.
As far as the exe, all you have to do is install the 8.5 run-time engine on the other PCs. If you had created an installer (something you should always do), the run-time would have been included.

How do I sort searches by project?

I am evaluating Aperture at its new lower price and really like it apart from one thing. When I do a search in iPhoto, or create a smart album, I have the option of displaying the results organised by event. This is great as I can, for example, search for San Francisco and get the results split by the trip I took them in. Nice.
As far as I can see, this is not possible in Aperture. A search of photos or a smart album just gives me a load of photos. I can set metadata to show the project name for each photo but that isn't the same. You have to look closely where one project starts and the next ends. The closest I can get is to search in projects and sort by folder. Now assuming that all my project are in folders (which they aren't and don't otherwise need to be) I get a nice view of projects (events in iPhoto speak) sorted by folder. However, this gives a preview of each project not each picture. In iPhoto I get the actual pictures in the events.
I'm amazed that I can't find a way to do this. Surely, when doing a search, its likely that the person is going to want to easily see where/when they took the shots.
Although Aperture has some great advanced organisational capabilities, it doesn't seem so advanced at the basics.
Does anyone know a clever way to do what I need?

Hi Andy. Welcome to the user-to-user forum.
Afaik, this is not possible with Aperture. I agree that it would be useful, and seems to a missing feature. Projects view appears to me to be added on to the side of Aperture, and not yet fully integrated with it. The collapsible Events in iPhoto would be a most welcome feature in Aperture (for Projects).
The lack of full integration of Projects -- with expanded metadata for Projects, a fully expandable/collapsable hierarchical Projects view, and the ability to show Projects view in one browser and images in another -- is one of my top criticisms of the current version of Aperture.
You can make feature requests to Apple via the Aperture menu. Select "Feedback".
While in Projects view you can skim Projects to see individual images.
You might be able to get a good bit of what you want by rigorous use of a Project-naming convention. (The search field in Projects view searches the Project name and description, and is different from the search field in Image view. +I think+ the search field in Projects view is the same as the search field at the top of the Library Inspector.)
You can also use the Project description field for tagging Projects. "{Shift}+i" brings up the Project description HUD.
You can go from a Project search to images. Double-clicking the Project in Project view search results is similar to clicking the disclosure triangle in iPhoto's search results view.
You can go from an image search to a Project. Right-click an image and select "Show in Project". When you return to the container you searched, your search is still applied. (There is no automatic way to go back.)
These last two deliver much of the functionality of the integrated iPhoto view you miss. In practice, it is useful -- but never elegant.

How to create LOV not based on a View Object attribute?

Hi,
I am creating a handed-made search form and I want to create an af:inputListOfValues.
I have :
- a read-only-view-object to get the LOV values from BD.
- af:inputListOfValues tag (droped from Component Palette).
How can I create the listOfValuesModel in Bindings layer? (the inputListOfValues is not based on a View Object attribute).

Sorry, I think I am not very clear in my posts.
My requirement is to create a LOV but I have no ViewObject. I just want an input (not based on a view object attribute), alone, but with a LOV (where lov's datas are get from a view object).
In a "normal" LOV I would have something like this :
in jsff :
<af:inputListOfValues id="departmentIdId"
                            popupTitle="Search and Select: #{bindings.DepartmentId.hints.label}"
                            value="#{bindings.DepartmentId.inputValue}"
                            label="#{bindings.DepartmentId.hints.label}"
                            model="#{bindings.DepartmentId.listOfValuesModel}"
                            required="#{bindings.DepartmentId.hints.mandatory}"
                            columns="#{bindings.DepartmentId.hints.displayWidth}"
                            shortDesc="#{bindings.DepartmentId.hints.tooltip}">
        <f:validator binding="#{bindings.DepartmentId.validator}"/>
        <af:convertNumber groupingUsed="false"
                          pattern="#{bindings.DepartmentId.format}"/>
      </af:inputListOfValues>in pageDef :
<listOfValues StaticList="false" IterBinding="EmployeesView1Iterator"
                  Uses="LOV_DepartmentId" id="DepartmentId"/>in model layer : a view object (EmployeeView) with view accessor and LOV based attribute, and a read only view object (DepartmentRVO) to get datas for the LOV.
But in my case I have no ViewObject, so I don't know how to create the listOfValuesModel in fragment pageDef.
I have :
<af:inputListOfValues label="Label 1"
                                popupTitle="Search and Result Dialog"
                                id="ilov1" model="here I want to point to a listOfValuesModel but I don't know how to create it"/>in pageDef : the listOfValuesModel but I don't know how to create it.
in model layer : just a read only view object (like DepartmentRVO), to get the datas for the LOV.

Searching for flash based forums, or a way to load forums into flash ?

Im searching for flash based forums, or a way to load forums into flash ? i found this
http://activeden.net/item/flash-forum/52576?page=1
Any ideas or recommendations would be greatly appreciated

You can load the raw html - if flash is told (e.g. via
flashvars) the url of the page that you want (its available in
flash as what you would think of as the browser's 'view source'
style plain text) with either as2 or as3.
But you can't do full browser-style rendering of the content
because flash just can't do all that. You could parse the raw html
(probably a custom parser as I think the internal xml parser might
choke on some of the tags in html that are not closed such as
<br> etc) and just pick out bits of text or images that you
could display but you can't achieve an embedded browser.
Adobe's AIR might be more what you want - it has embedded
browser support- but it doesn't run inside a browser like flash.

Business components based on Oracle views

I am trying to create business component objects in a master-detail relationship based on Oracle views rather than on the underlying tables. The wizard does not create associations or links since the views have no foreign keys. I created the associations and links myself, but I am unable to add them to the data model. I am using the beta v5.0, but I had the same problem in v3.23. Can anyone help?
Thanx in advance

[*]SQLPLUS SCOTT/TIGER
[*]CREATE VIEW DEPT_VIEW AS SELECT * FROM DEPT;
[*]CREATE VIEW EMP_VIEW AS SELECT * FROM EMP
[*]On my workspace: Right-mouse / New / Empty Project
[*]On my new project: Right-mouse / New Business Components...
[*]Next, to the connection panel
[*]Set the connection, and next
[*]Pick a package name and next
[*]Tick the [x] Views checkbox, and select EMP_VIEW and DEPT_VIEW
[*]Uncheck the "View Objects and View Links" box, since we don't want these created automatically.
[*]Click (Finish)
[*]In navigator, select my "DeptView" entity and edit it (the view is called "DeptViewView").
[*]Click on the "Attributes" tab
[*]Select "Rowid" in the attribute list
[*]Click the (Remove) button
[*]Select the "Attribute Settings" tab, and select the "Deptno" attribute.
[*]Check the [x] Primary Key checkbox for "Deptno"
[*]Click (Ok).
[*]Repeat steps above on "EmpView" entity to remove Rowid attribute and make "Empno" attribute the primary key. (NOTE: Since views don't have constraints, we couldn't detect the primary key constraint, so we default the ROWID to be the primary key in the wizard).
[*]In navigator, select my "DeptView" entity, and right-mouse / New Association...
[*]Using the wizard I create a association based on the "Deptno" attribute, and with a 1 to many cardinality.
[*]I right-mouse on "DeptView" entity and select New Default View Object... to create the "DeptViewView" view object.
[*]I right-mouse on "EmpView" entity and select New Default View Object... to create the "EmpViewView" view object.
[*]I right-mouse on the DeptViewView view object and select New View Link...
[*]I create a new view link between DeptViewView and EmpViewView
[*]On the "Source Attributes" panel, I select the "Dept2Emp" association I created above, and click the ">" to shuttle it to the selected list.
[*]Click next and notice that by selecting the association, it automatically picked the right attributes for both sides for the view link automatically.
[*]click next, then (Finish)
[*]I right-mouse on my package and select New Application Module...
[*]On the datamodel panel, I see a tree view of "Available View Objects like this:
