Good answer. I despise the hall monitors in these forums. (Relax, cut back on the caffeine, go outside there's this big ball of file in the sky you might find interesting). I might understand if someone is abusing the forums with repeated and unnecessary cross posts. But come on... this person, for example, has a sincere question that may be better served because the question is posted on a couple of different forums.

  • JDev TP4 DVT:Map Component: How to send a command to Mapviewer Server?

    How to send a command to Mapviewer Server programmatically using a DVT:Map component? ( for example : To capture a Theme info when i clicking in the a map theme position?
    Juan C LLanes

    Hi Juan,
    Are you trying to click on a point in the map and update another control on the page?
    This is available today, if you create a master-detail binding and bind the master to your map theme, and detail to another view e.g. a table, and check the checkbox "Enable row selection" when you create the map theme binding, then you will get this behavior automatically.
    If this is not what you are looking for, please clarify.
    Thanks

  • How to send a command from a vc++.exe to LABVIEW.exe in order to control the button on the LABVIEW.exe

    Hello, everyone. Using VC++, I have gotten the handle of a *.exe(built by Labview), but I cannot get the button handle. I want to get the button handle and post the message to control the button. How can I do that? When I use the SPY++, the *.exe(built by Labview) have not any child windows which is very different from the *.exe(built by VC++). In SPY++, what is the LVDChild class? How can I send the message to control the button on *.exe(built by Labview)???

    Checkout the LabVIEW ActiveX server interface in the User Manual in Chapter 20, Windows Connectivity and the VI Server Reference in Chapter 17, Programmatically Controlling VIs.
    There is a sample for Visual Basic under examples/comm/VBtoLV.frm, which should be quite simple to translate to Visual C as long as you can figure out the basics of ActiveX programming in VC (I have never done anything with ActiveX in VC). For those basics I would recommend some text book or MSDN.

    Hi,
        for the      Points.
    The Sending computer does not have to be in the United States (It used to with older versions of iChat)
    However I would think you meant the phone is not in the United States either.
    iMessages is still going to need to know where in the world a iPhone number is so the pic as a Contact number that looks too small.
    It is possible that Yosemite may only do SMS in certain areas of the world to start with.

  • How to send SCPI commands to a VXI instrument

    I am using a VXI Interface tech SR2510 LVDS card with teststand and keep getting the following error when the intial diagnostics test trys to run. "Device I/O Driver error" I tried to use the Visa Interface and the interactive control in NI MAX but was not able to send SCPI commands. What can I use to communicate with this card. The resource manager does successfully execute and I see my instrument in the devices list so I am confident it is not a VXI problem.

    Hello DF1963,
    Can you communicate with the card through its driver/interface? Also, please review the following NI-VISA Help topic: Introduction to Programming VXI Devices in VISA to ensure that correct commands are being sent. If your device is correctly configured in MAX, I would also recommend verifying with the card manufacturer as well.

  • How to send a command in Hex to serial port

    I need to send the following command to serial port
    [SS] [1] [CR] to serial port , how do i do that in Hex

    Norman,
    Learn to write a single commands and get back a valid replies first, before
    you try to develop an app to continuously communicate with the instrument.
    Once you get the command set down, you can plug them into your state
    machine.
    Attached is a VI about ASCII to HEX and Carriage Returns.

  • How to send this command to RS232 Port

    I want to use LV to control a label printer to print what I need. Following info is from printer user manual.
    From RS232 port:
    If Codex has been used with the controller then the simple serial protocol will need to be enabled by sending ESC Z SWITCH ON <CR> (without spaces). Codex automatically disables the simple protocol for security reasons, so it is a good idea to start all sessions with this command.
    ESC Z S W I T C H O N <CR>
    à From BASIC the first line would be CHR$(27)+”ZSWITCHON”+CHR$(13)
    Send the following ASCII data to the RS232 port:
    ESC J 0 C H R I S T M A S <CR>
    ESC J 1 A N D   S E A S O N S <CR>
    ESC J 2 G R E E T I N G S <CR>
    ESC J 3 T O   M Y   H E L P E R S <CR>
    ESC J 4 0 9 8 7 6 5 4 3 2 1 2 1 <CR>
    à From BASIC the first line would be CHR$(27)+”J0CHRISTMAS”+CHR$(13). Etc.
    In VB I can use this command to control the printer. But In LV how can I do?
    I'd appreciate it if anybody give me a simple sample.

    A string control or constant in LabVIEW can be set for normal, hex, or '\' code display by just right clicking on the control constant. CHR$(27) is the the ESC character and the hex equivalent of 27 is 1B. The CR is hex  0D. So, a simple way to do this would be to have a hex display constants for the ESC and CR character and a normal display for the the command. Use the concantanate string function to build one string.

  • How to send multiple commands throught the Instrument I/O Assistant

        I am using the Instrument I/O Assistant to set up an instrument driver.  I am only using two rs 232 commands. The way I have the Instrument I/O Assistant setup is: first I have a default instrument setup step then I use a write step with the first command, then I read and parse, then I do a write command again with the second command and finally I read and parse again.  All of this works fine inside the window but  when I run it in my program  only the first  command's response it outputed . The second command's response is not outputted it just sends a null. Can the Instrument I/O Assistant only handle one read and write, or is my logic wrong?
    Thanks for your help
    Ian

    Hi Ian,
    You should be able to perform multiple reads/writes with the Instrument IO Assistant.  What termination character are you using?  I have seen cases where different termination results in different parsing, which may explain why you're only receiving a null character on your second read.  Thanks!

  • How to send AT commands with JAVA?

    Hi,
    to get the cell id on a mobile phone I would like to send "AT+CREG=2" as an AT command to the mobile phone.
    Is there an API for getting network registration things like the cell identification of a gsm mobile phone or is there a possibility to access the mobile phone with AT commands?
    In MIDP 2.0, there is the possibility to access serial ports of a mobile phone. Probably this will work?
    I would be glad, if anyone could give me an idea. I'm investigation since weeks.
    greetings,
    Ralf.

    Hi
    i really don't know, but when i read your posting i thought that this may not be possible because it would break the java security concept.
    I guess, if you'd like to get any plattform/device related information you would need to have a vendor/device specific api.....
    but as i said, i don't know, i just guess...
