How to create the TCP non-blocking server?

Hello

I would like to have a TCP server at my request.  It will go about their business as usual, but in the background a TCP server sits waiting for a client connection.  If such a link exists, the normal code will send stuff on this topic otherwise it will just not send.  Currently, I do not see how to stop this blocking while it waits for a client (block waiting on TCP listener).  I looked at the example of client/server TCP, but it remains blocked in the same way.

I would like advice on how I'm framing such a request.  I also want to do the same on the client side.  Go about business as usual and if a connection can be established at a time given, then send stuff on that connection otherwise just not worth it.

LabVIEW parallel code usually runs in parallel. This is true even a wait - if inside a loop, you wait 100ms and other code in parallel, it is not delay execution of other code, rather he runs forward and the other code at the same time. When both have completed, the loop can proceed to the next iteration. So yes, if you have a loop with a 1000ms wait and another with an expectation of 100 ms and waits take longer to execute any parallel code in loops, then the loop of 100ms will last about 10 times as many times as the loop with the 1000ms wait.

I recommend that you put the waiting on the listener in a separate loop and also have another parallel loop that manages the communication when the connection is established. You can then use a timeout (forever) of-1 on waiting on the listener, and this loop will be almost never run or use resources except what is first of all establish a connection. To kill this loop, close the listener somewhere which depends on waiting on execution of the listener. When a new connection is established, put the link in a queue, where the communications loop can pick it up.

    You can:

    (1) in the tool box, set the fill to none;

    (2) in the appearance palette dialog box, click Add new fill;

    (3) with the new fill selected / highlighted in the main window of Apperance palette, apply the gradient.

    In the case shown and similar, you can click the gradient in the Toolbox instead of filling Uni, then change the colors in the palette degraded for each stop end of levels of grey, white and black for the right colors in the color palette (RGB or CMYK), then add stops with intermediate colors. you select / Create to stop clicking in the gradient bar, and you can move the stops in ClickDragging or by setting the percentage values.

    Hello

    can someone explain how to refine the Vmware host windows server edition?

    Hello

    First, you decide what you want to use the VMWARE server.

    If you want to use vmware server for only to keep the plane comments at end of test system administartion, during the installation of VMware server you will need to customize your installation.

    In the Customize installation disable the Modules Perl script which are used for development purposes, after installing the server, go to services & disable services unwanted, assume that you use no DHCP & NAT, then disable these services. In doing so, it will save the memory & performance increase of you host mechine.

    When you create your mechine comments try to reduce unwanted devices, how to remove the floppy drive if you don't want to use in the mechine comments. like this, try to reduce the additional devices you use rarely, if you're runnin server edition comments mechines, then try to reduce you is display resolution, which will give a good performance.

  • Satellite P750 PSAY1A: how to create the recovery Toshiba on the new HARD drive partition

    Hello

    I have an old Toshiba Satellite P750 (PSAY1A-01Y022). I just upgraded my memory from 4 GB to 8 GB and am preparing to take my 500 GB HARD drive 1 TB. I had to order the disk online and wait to happen.

    I always try to understand how to create the arrival of my new HARD drive Toshiba Recovery Partition. I do the same thing for an old book, I handled based on something similar to it's original factory State.

    I have reflected on the recovery partition, but does not know how it was created. It is not NTFS. Does anyone have experience in the creation of a Toshiba Recovery on a new HARD drive Partition?

    And the help is very appreciated.

    Thanks and regards,
    Dinesh

    Recovery partition can be created when you use the original Toshiba Recovery disk and install recovery image. Before the partitions to boot OS install will be automatically created, recovery image copied on a recovery and then partition as last step recovery image installation starts.

    A sort of migration of files from one to the other HARD disk is not solution.

    Only for laptop with factory will work and the usable recovery partition.

  • How to create the scroll to the menu icon click event bar

    How to create the scroll to the menu icon click event bar

    (as the "field of scrolling image")

    In my opinion, it is better for you to try something to help implementation of your solution to ask for the code.

    For example, create a few BitmapFields with icons that act as buttons.  There is source for this sort of thing on the forum if you look at, I think, looking FRO Image button, icon or Bitmap button.

    Once you have these buttons work, add these in a HorizontalFieldManager.
