Using input demo for PDA

Hi,
i´m trying to develop an app that will have to work with the camera in my PDA (model: Qtek 2020).
My app has to be able to use the camera button, not to open the default camera application but open my own camera application.
I have already found a camera API that will allow me to work with the camera using .NET.
My problem is working with the camera button. I have tried LabVIEW
example (...\National Instruments\LabVIEW 7.1\examples\PDA\input\input
demo.vi and also attached) but it doesn´t
returns the value of the camera button. Also, the default camera application doesn´t open when i press it.
Because the default camera application doesn´t open, LabVIEW knows that the button exists, so why doesn´t it returns it value?
If anyone has any suggestion for using the camera on a PDA with LabVIEW PDA Module, i would appreciate.
Thanks,

  • Do I need to use DAQmx Base for PDA module or DAQmx will work just fine?

    Hi All,
    Does PDA module work only with DAQmx Base or DAQmx as well?
    hellolv

    Hi hellolv,
    The PDA module currently only works with DAQmx Base.  If you've never used DAQmx Base before, it is actually very similar to DAQmx, and there are lots of examples out there to get you started.  I recommend searching through our Example Code Library.

  • Dropdown funda using input field

    Hi
    I wanted to do something as follows
    in drop down u have options rite so i wanted those drop down options in a inputfield
    meaning when the user clicks on some button besides the input field then i want to open a drop down kinda box where all the options are displayed in the form of a tree and the user selects it it should be populated in the input text field ( i know that we can use a pop up window and a table with all the options inside it but i want this in a tree view and that to the dropdown like box should be xactly below the input field) any help will b appreciated.
    regards
    sudheer

    Hi manoj
    there is some reason behind why i am using input field for achieving this drop down functionality
    i have achieved what i want by doing the following way
    i have changed my layout to row layout and in the first row i have created the input filed and a button
    and in the second row i have created the tree structure i wanted and made it as invisible ok
    when the user clicks the button the tree will open up and the according to what the user selects i have set to the context from which the input field is set ( so the selected thing has ben displaying)
    the problem in this method is
    all the contents which are after the row 3 are moving down when i am making the tree visible which i dont want
    so i am searching for the alternatives. i know that EVS or SVS will help but according to my need i want a tree with options rather than table with options( as the case with EVS or SVS )
    any ideas will help me alot
    thanks and regards

  • WebI 4.0 using BEx Query - #TOREFRESH when using input control

    Once I refresh my webI report for certain month range and then I use input control for analysing my data within that month range. It always ask for refresh "#TOREFRESH".
    The above happens also if I have lot of formula variables in my report then it always ask for refresh when I use input controls on different member.
    Please let me know if this is a known issue.
    I posted this in Ideas too - >  https://cw.sdn.sap.com/cw/ideas/9226?back=false
    Thanks

    #TOREFRESH normally indicates that the returned data have dependencies for which you need to manually refresh again to pull the correct data however this would incorrectly appear under some circumstances.
    Please see [Using Functions, Formulas and Calculations in SAP BusinessObjects Web Intelligence|http://help.sap.com/businessobject/product_guides/boexir31SP5/en/xi31_sp5_webi_ffc_en.pdf] for additional information.
    If you are below SP3 FP3.7 we suggest to upgrade to that patch level or better to SP4 FP4.1 or SP5

  • Can I use a MIDI keyboard as an input device for a software instrument?

    I have a Casio CTK-2100 that I am currently playing around with in Logic Pro 9. It can record and playback the different instruments fine using MIDI tracks. But I was wondering if it is possible to use the keyboard as an input device for a software instrument instead of the "Step Input Keyboard".
    Is it? If so, how do I set it up?

    Yes, the terminology can be a bear, many, many years ago when I started using Logic the manuals were written completely by the programmers, while they were quite humorous in places the were also really hard to understand so I learned/realized.. you can't really do anything so wrong it's going to destroy your computer so why not go ahead and experiment. I learned the basics of Logic without a manual, months later when I went back to find some some details I could figure out the manual made a lot more sense.
    Logic has been somewhat Appleized but it's not really an Apple program, it was purchased almost as developed as it is now... a lot of the additions a fluff to make it easier to understand for new users while at the same time there are some real improvements.
    This is personal opinion: With all of the forums/online tutorials...etc...etc. It seems users are learning (but not understanding) the same things, plus everyone wants to use it right away so nobody takes a deep breath and investigates on their own. Logic is a deep, deep program, while learning don't be afraid to go off on a tangent and explore the program without any other input, it can actually be inspirational. One other thing good about the manual or "Online Help", in looking up a function you will invariably come across a related concept that will provide further insight.
    And..... have fun.

  • Date Format on OWB 11.1.0.7 to use for input parameter for a mapping

    Thanks,

    Hello Shaun,
    The function wb_rt_conversions.from_date is (at least in OWB10.2) overloaded and can with input-types as
    date, timestamp_unconstrained, timestamp_tz_unconstrained, timestamp_ltz_unconstrained or varchar2.
    If it doesn't work with varchar2 I would try Date:
    For example: to_date('2010-01-01','YYYY-MM-DD')
    I also found this thread:

  • Is it save to use digital output as a digital input signal for another channel

    Hi all,
    I know this is a stupid question, but I do not have other signal generator by hand. So what I want to know is, can I use the digital output signal of my USB-6001 as an input signal for the same device but on other digital port? I did not try out directly because I do not want to burn the device down......
    Thanks
    Solved!
    Go to Solution.

    I do loop backs all the time, especially in my test systems as a way of making sure my signal is making it to the UUT pin.  I typically throw in a 10k resistor just in case, but I have never had an issue.
    There are only two ways to tell somebody thanks: Kudos and Marked Solutions

  • Curiosity: How to use a table for input when testing a functionmodule?

    actually I am sick of writing test programs for every function I want to test using ABAP.
    So why it is (made) impossible to generate input data for a table as input parameter of a functionmodule?
    Has really nobody ever tested this stuff when the test function was implemented in SE37 or was this bug implemented on purpose to generate work?

    Andreas,
    You can input data into the internal table by:
    Test FM
    > Testing initial screen --- click on the table icon against your table parameter
    > Input your input data in the fields
    > to Input more lines in the table.. press Insert Line (icon with plus sign)
    After this press back button.
    Now, you will have your test data in the tables.

  • How can i write a vi in using parallel port for digital inputs

    Dear all,
    i am a beginner user of LabVIEW and i want to write a vi in using parallel port for digital I/O. After reading the article "Using the Parallel Port in LabVIEW
    " and download the parallel.zip, i know how to write the vi for output, but i still don't know how to write the input one.i've try to use a Inport.vi to test, but nothing change when i set pin2-9 to high. (my computer:win2K & LabVIEW 6.1)
    Can anybody teach me how to write it?
    Can anyone write the vi for me too?
    Thanks all!
    p.s.i've already install the "accessHW.exe"

    Are you using VISA or the accessHW VIs? You may need to goto the bios and set the parallel port to run in spp mode or standard mode. This is the simpliest configuration and where you should start.
    As far as writing the VI goes, just copy the diagram out of the tutorial you mentioned.

  • Using the Formula Node for PDA

    I get a compile error when I use C code inside the formula node. Is it possible to use C Code inside the formula node for PDA applications? Do I have to include any file while building the executable for the PDA

    Ok, I was able to successfully build an executable file without error. I attached the screen shots of your program in execution. Does this look like the desired result?
    I'm confused as to why I can build and run the program on my machine. I have LabVIEW 7.0 and Windows XP. What version of Windows and LabVIEW are you using? Also, are you getting the error window when you try to build an executable or when you attempt to run the VIs within LabVIEW?

  • How to get default input values when using promt user for input

    I use "promt user for input" to input some values. The messageboard appears with blank boxes then I will input  new values. I want to make some default values in this blank boxes so that I needn't to enter new values. Is it possible ?

    Right click on he Express Vi terminal and choose open Front panel to convert it into a standard vi. Then open it. Enter a default value for each control, then right-click on the controls and go to data operation > make current value default.

  • Use RT Communication Wizard to build application for PDA

    Hi,
    I am wondering if the RT Communication Wizard can be used to build the Host, NPL and TCL VIs for PDA touch screen pocket PC model NP 606S.
    I am familiar with using RT Communication Wizard to build RT set of VIs for communication between PC and cFP-2020 field point.
    Now I need to go step further and develop the similar VIs, one VI (NPL along TCL) that will run on the RT Target (my field point) and Host VI that I will compile and run from PDA (NP 606S). I am using cross-over Ethernet cable (TCP communication).
    If this is possible to do, are there any special instructions (rules) to complete the process properly.
    Thanks in advance,
    Peja

    I don't use the RT comm wizard, but after generating a small sample program, my answer would be yes. The RT part is only on the RT side. Programs written using the PDA module use the TCP VIs just like regular programs and I have used them to talk with a FP, so it should work. You should keep in mind that the display on PDAs is limited (no clusters, no arrays and so on). Since, according to this, the NP 606s isn't a PDA, it's possible it will be able to display them (although I doubt it).
    Try to take over the world!
