How to determine the length of the string when the string using LabVIEW MoveBlock pointer dereference

Hello!

Calling a DLL that returns a pointer to a structure consisting of a pointer to a string, a 32-bit integer and a pointer to another string.

I managed to MoveBlock to return a consolidation of these three things, and which works very well.

But now I need to read the two strings I have pointers to which are not fixed length. MoveBlock has a size of entry, but how to know how long channels are?

Try this:

...\vi.lib\Utility\importsl\GetValueByPointer\GetValueByPointer.XNode

Wire just a constant string to the Type of entry.  If I remember correctly, the draw of endpoint (assuming that the C strings) will be included.

Sometimes I have just MoveBlock a byte at a time until I get to a null value or has specified maximum size.

    Hello

    I am new to LabVIEW, and I need help with the configuration between LabVIEW and the controller. My PLC is Omron CJ1M-CPU11-ETN21. I have the DSC Module and I have an OPC server as well. I create tags or even used the shared variables to try to write to the output of the PLC, but it does not work. The configuration for the ethernet Powerline had done, and I can control the PLC using CX-program via the Ethernet module. May I know what are the problems?

  • How to determine the number of highlight ' to write ' for DAQmx generate analog output?

    On the configuration of the stage for DAQmx generate analog output, there is a field "value to write.  I can't find any explanation for what it is, how it determines the value to enter, nor what he writes.  I am trying to go through the tutorials and it cling.

    Someone would give an explanation?

    Hello

    To write value specifies the value to write in the channels, lines or ports selected in string parameters. In other words, this value will be the value of your DC output (for example if you enter 5, your output will be 5V). To get information on different fields in SignalExpress, access help"context-sensitive help. A pane will appear in your work environment that displays the coordinates of the field when you place your pointer over them.

    For new users of SignalExpress:

    Generation of DC signals with NI DAQmx devices: step in the DAQmx build, select 1 sample (on request) in the generation Mode dropdown. You can select a programmatic input to generate, or you can remove the check mark from the check box use programmatic input and specify a value for generating in the field of value to write . NOR-DAQmx help also provides additional information about the data generation.

  • How to determine the amount of memory shipped on the PXI-5114

    How to determine the amount of memory onboard, I have on my PXI-5114?

    Thanks in advance.

    Hello

    I'm sorry I didn't know you already had the map.  There is a property for NO-Scope node to determine the total amount of available memory that we can then divide down to get the memory available per channel.  Please see the vi and help below:

    This gives a shot, just drop it in a VI that you use and if it should return your memory cards.  If you don't have a LabVIEW I can probably retrieve the purchased version by querying your serial number.

    Kind regards

    There are two ways that windows can determine the location of the computer.  The most common is through the ip address.  The Ip address is assigned to the netwrok by the ISP.  You can determine the location of his similiarly IP network how to determine the place of a phone number of his area code.

    Also what you do online can casue of many sites infer you the location.  For example, if you use goolge to search a lot of things in Minneapolis, they deduce that you live in this area will serve as announcements concerning this area.

  • How to determine the ROWNUM in a Master detail form

    Hello

    I work in a master detail form with controls and information in order of points; I have created a process that allows users to select a product on a tabular presentation ID and the next column is filled automatically with the Product Description.

    To achieve this, I followed some instructions by Denes Kubicek (http://apex.oracle.com/pls/otn/f?p=31517:241), but my case is slightly different:

    < ul > I use a form tabular-created by Wizard, instead of manual tabular form; and < /ul >
    < ul > instead of using another page as a Popup to pass the parameter of the ROWNUM, I use a plugin called "tabular form Super LOV" which is a modified version of Super LOV the SkillBuilders who works on tabular forms. < /ul >

    The product ID is returned in the line by the plug-in; but in the case of the Description of the product, it is always returned in the first row; and my problem is that I don't know how to determine the line where the user clicked to call the plugin.

    I created an example in apex.oracle.com in case someone wants to look at:
    Workspace: ediazjorge
    User name: test
    Password: test
    App name: Sample App
    The app number: 1550

    BTW, I use Apex 4.1.1.00.23 and Oracle DB 10.3.2.

    Thanks in advance,
