Increment once with KeyPress

I have trying to find 'good' to make this concept of basic method to increment a value (in this example) once with KeyPress:

Is there a more efficient (using less cpu and/or less code) to do this?

I am also curious, why you cannot add records to shift to the structure of the case.

He gets not much more effective than that. It is an increment '+ 1' primitive in the digital palette that makes the code a little bit smaller, but I suspect that the compiler is smart enough to spit out the same thing anyway.

It is considered to be best coding style for using a structure of the event to react to orders rather than the election. Who will no doubt save a small CPU drain, although I see that you have an expectation of 50ms in your polling loop to curtail it being too greedy.

Shift registers are meaningful on the structures that implement a loop, a case is not. You can create records to shift on your outside while loop and wire.

  • Customized backup (incremental) Oracle with database control

    Hi all

    I m running on windows server 2008R2 oracle 11 g R2.

    I want to schedule a backup customized with control of the database to plan my backups. (This is the second option of the database-> scheduled backup control)

    I want to have a window of 7 days recovery.

    I'm a little shaky on how to plan properly.

    I need to schedule backup complete everything first (by checking the option use as a base for incremental backups). (This should go once)

    Then schedule incremental backup every day after that?

    Could someone explain how to set up the right then that I would have a window of 7 days recovery?

    Thank you.

    Hemant thanks for your explanation on L0 backup.

    So I go ahead and schedule backup complete once a week! I understand that part. (let's say I plan backup complete Sunday night)

    What about backups of L1?

    Should I plan Monday to Saturday sound? Or can I include it on Sunday as well?

    The reason I ask is, I don't know if the Manager of the company will allow me to schedule backups every day (except a certain day) m.

    I will give this a shot!

    Thank you!!

  • Timed loop runs only once with pulse train?

    It is a VI that attempts to drive a loop timed with a train of pulses 6608 OR map attached.  My timed loop never appears to run more than one cycle.  No error is reported.  I suspect it's because I'm not set up correctly with NOR-DAQ.  Any help would be most appreciated.

    WB

    Hi Wb,

    Take a look near the timed loop, I can see that the value of dt period is set to 1000. This period is used to scale based on synchronization source units. In this case, the clock contains 0.5 second pulses. Change the dt to a value of 2 has allowed me to see the timed structure to go as planned. See the image below for more details:

    I hope this helps. Let me know if this behaves that way even on your system.

    See you soon!

  • How to remove data in three tables at once with the same key.

    I am new to Oracle ADF, I have a requirement like these, I have three tables such as employee salaries, teams of all these have a common EmpNo as common attribute, I have the search form these returns all employees related to this search query, when I click on the button Delete the particular employee data should delete all tables of the three based on the EmpNo.



    Any help is appreciated...

    (1) the easiest way is to mark the constraints of foreign key to WAGES employees and TEAMS of EMPLOYEES like ON DELETE CASCADE. The DB server then removes the necessary lines each time you remove a line from the employee.

    (2) another way is to implement a Before delete e-DB trigger on the EMPLOYEES table, where you can remove the related rows in other tables (have in mind that if you have foreign keys you can get an Exception Table mutation, so this approach is perhaps not very good).

    (3) an ADF is to implement a custom EntityImpl class for the Employee entity and substitute the remove() method where you can find the related entities of TeamMember and salary (via EntityAssoc accessors) and call remove() methods too.

    (4) another way of the ADF is to implement a custom EntityImpl class for the Employee entity and override the doDML() method where you can remove the lines needed in SALARIES and TEAMS through JDBC calls tables whenever a DELETE operation is performed on the Employee of the underlying entity.

  • Trying to record several tracks at once with mixer (two microphones)

    I have an Alesis Multimix 4 and two microphones plugged into the mic 1 and the two mic inputs.  I am trying to record both at the same time, in two separate ways.  I put Device Class on ASIO in the section hardware Audio and delected ASIO4ALL v2 for the device.  My mixing table (I guess) appears as CODEC audio USB in the ASIO4ALL settings.  When I return to my multitrack setting, I gives me four options for the incoming audio signal:

    Audio Front Mic Input 1

    Audio Front Mic Input 2

    USB Audio CODEC 1

    Codec USB Audio 2

    No matter what combination I try, when I record, the two tracks pick up the two microphones.  My goal is to isolate the two, so I can apply different settings to both titles later, adjust the mix etc...   Audio only comes when I take the USB Audio option.  Thanks in advance.

    Brett

    I think you have the right driver selected, otherwise there Wouln't work not at all. The most obvious thing to ask you if (I'm sorry if this is too basic) is where you have the pan value orders? For each microphone to record on one channel, you will need to have a panned far left and the other right hard panned. If you let the two dead panned Center, that's exactly what you get - the two microphones on both channels.

  • Connect with user name more then once

    Hello

    I'm having a problem. I can not connect through auth Web page from a controller 4404, and once with the same user name. I get an error telling me to many connections with the same username, when I try.

    We have our maximum novell connection set to unlimited on my account and on behalf of students 2. LDAP a bridge between the controller and novell.

    Any thoughts on how I could get multipul connections at work?

    Brandon,

    Take a look under Security > Policies(pulling this out of memory, so it may be Management not Security) user.  There is an option for the number of simultaneous connections.  If you set this to 0, it will be unlimited.

    See you soon,.

  • Analog outputs with different time scales

    I use products AO of a card PCI-6731 for an application scan head and I have some difficulties to achieve peak performance, that I need. I am contolling the map with nidaqmx drivers in c ++

    Basically, an output controls scanning in the direction Y (which is a line of scanning and is very fast) and the other in the X (increment once per scan line, so much slower). The complication is that both exits start at an external trigger, because positioning is synchronized to a separate data acquisition card.

    Now, what I do is:

    -write the scanline for 0 output waveform

    -set output 1 to a given position

    -say next Trigger output card

    -hangs at the end and stop tasks

    What I really want to do, it is just tell him to start with on each external trigger output waveform of scanline 0 and output 1 increment to the next position. So I could do a complete 2D scanner with a minimum of control software.

    Any ideas on how I could best achieve this? My understanding of the nidaqmx drivers I don't see an elegant way to do it.

    I could potentially do some operations on the done callback, although it makes me a little nervous because the control PC running windows, it is not a real-time operating system.

    Hmm I do not know exactly but there are a couple of things (it is close)...

    The output frequency of meter in your example 5 MHz (20 MHz, 2 high ticks, weak 2 ticks), which is faster than holders 6731 for a sample clock.  I thought that this would have given a material error... are you looking for errors once the task runs (for example using DAQmxIsTaskDone)?.  There is a DAQmxCreateCOPulseChanFreq if you want to set the clock frequency directly (it will use the appropriate default internal time base).

    The task of counter generates 1000 pulses per trigger, is what determines the number of samples generated by the trigger (I assume that you want it to be 1024 aka "numSamples").

    The analog output task must either use:

    (1) calendar continuous if the output will repeat indefinitely as several triggers are acquired.

    (2) finishes pitch (N * numSamples) samples where N is the number of lines that you want to exit and numSamples is the number of samples per line.  In this case, the task will end once the lines were triggered.

    Best regards
