Visual basic and series

status = viOpenDefaultRM (defaultRM)
status = viStatusDesc (defaultRM, State, response)
readingslist. AddItem "viOpenDefaultRM" & Hex (status) response

' status = viOpen (defaultRM, "GPIB0::6:INSTR", 0, 0, vinstr)' good work with gpib
status = viOpen (defaultRM, "ASLR1::INSTR", 0, 0, vinstr) "does not when you use series

Might some understand why I'm not able to open the COM1 port using the visa above in visual basic command. I'm not having any problem when you use the GPIB0, I need to use both type of communication.

I have visa32 and visatype loaded into modules.

Well, I feel so stupid, I did not write "ASRL1" by "ASLR1".

It's working now.

Thanks for your help

  • Order to kill Visual Basic and Windows domain Policyies

    We have a program more former that uses files in the folder root (C:\) thus produces a file in there when you use a command to be sent to the screen.  At the end of this programming, it uses a VB Kill command to remove the file that it created.

    In a domain environment, the policy prevents all to allow this file to be killed.  What is the policy for this, so I can assign users and groups to enable them to kill this file.

  • buffer size and sync with the cDAQ 9188 problems and Visual Basic

    Hi all, I have a cDAQ-9188 with 9235 for quarter bridge straing caliber acquisition module.

    I would appreciate help to understand how synchronization and buffer.

    I do not use LabView: I'm developing in Visual Basic, Visual Studio 2010.

    I developed my app of the NI AcqStrainSample example. What I found in the order is:

    -CreateStrainGageChannel

    -ConfigureSampleClock

    -create an AnalogMultiChannelReader

    and

    -Start the task

    There is a timer in the VB application, once the task begun, that triggers the playback feature. This function uses:

    -AnalogMultiChannelReader.ReadWaveform (- 1).

    I have no problem with CreateStrainGageChannel, I put 8 channels and other settings.

    Regarding the ConfigureSampleClock, I have some doubts. I want a continuous acquisition, then I put the internal rate, signal source 1000, continuous sample mode, I set the size buffer using the parameter "sampled by channel.

    What I wonder is:

    (1) can I put any kind of buffer size? That the limited hardware of the module (9235) or DAQ (9188)?

    (2) can I read the buffer, let's say, once per second and read all samples stored in it?

    (3) do I have to implement my own buffer for playback of data acquisition, or it is not necessary?

    (4) because I don't want to lose packets: y at - it a timestamp index or a package, I can use to check for this?

    Thank you very much for the help

    Hi Roberto-

    I will address each of your questions:

    (1) can I put any kind of buffer size? That the limited hardware of the module (9235) or DAQ (9188)?

    The samplesPerChannel parameter has different features according to the synchronization mode, you choose.  If you choose finished samples the parameter samplesPerChannel determines how many sample clocks to generate and also determines the exact size to use.  But if you use streaming samples, the samplesPerChannel and speed settings are used together to determine the size of the buffer, according to this excerpt from the reference help C DAQmx:

    Note that this buffer is a buffer software host-side.  There can be no impact on the material available on the cDAQ-9188 or NI 9235 buffers.  These devices each have relatively small equipment pads and their firmware and the Driver NOR-DAQmx driver software transfer data device to automatically host and the most effective way possible.  The buffer on the host side then holds the data until you call DAQmx Read or otherwise the input stream of service.

    (2) can I read the buffer, let's say, once per second and read all samples stored in it?

    Yes.  You would achieve this by choosing a DAQmx Read size equal to the inverse of the sampling frequency (during 1 second data) or a multiple of that of the other playback times.

    (3) do I have to implement my own buffer for playback of data acquisition, or it is not necessary?

    No, you should not need to implement your own stamp.  The DAQmx buffer on the host side will contain the data until you call the DAQmx Read function.  If you want to read from this buffer less frequently you should consider increasing its size to avoid the overflow of this buffer.  Which brings me to your next question...

    (4) because I don't want to lose packets: y at - it a timestamp index or a package, I can use to check for this?

    DAQmx will meet you if all packets are lost.  The default behavior is to stop the flow of data and present an error if the buffer of the side host DAQmx overflows (if, for example, your application does not pick up samples of this buffer at a rate equal or faster than they are acquired, on average).

    If, for any reason, you want to let DAQmx to ignore the conditions of saturation (perhaps, for example, if you want to sample continuously at a high rate but want only interested in retrieving the most recent subset of samples), you can use the DAQmxSetReadOverWrite property and set it to DAQmx_Val_OverwriteUnreadSamps.

    I hope this helps.

    Gracias por su ayuda y tiempo

    Hi fvega,

    I'm not aware of any binding Berkeley DB written directly in Basic. However, there is a .NET for Berkeley DB written in c# library and the library must be accessible to the other languages in accordance with CLS as well, as a result, Visual Basic .NET included:
    [Berkeley DB for .NET | http://sourceforge.net/projects/libdb-dotnet/]
    Maybe you can use the .NET framework and switch from Visual Basic 6 to Visual Basic .NET (vs 7 or later).

    If the above didn't help not you could start by analyzing our SWIG code (it is in 'db.i', under 'BDB_HOME/libdb_java') and decide what additional SWIG code you need to add for Visual Basic 6 specific API mapping (data flow between Basic and C).
    If you find yourself eventually wrote such a link, please do not hesitate to post here all the details so that others can benefit from.
