  1. VS 2019 Re: [RESOLVED] Sending Live Data Out of Serial Port (Data is not Updated by itself)

    Agree 100%. My assumption was those labels are also visible somewhere so you can still see the data.
  2. VS 2017 Re: Print specific data from data grid view, and auto print from scan gun-

    I would guess that you would add an action of Insert ASCII character for each of those characters so your prefix rule would be 30 actions long assuming you used that filename.
  3. VS 2019 Re: [RESOLVED] Sending Live Data Out of Serial Port (Data is not Updated by itself)

    Since I don't see another thread from you yet, normally you "self-update" was is received on a SerialPort by handling the DataReceived event, which will fire as soon as a character comes in unless...
  4. VS 2017 Re: VS 2017 how can i loop in richtextbox and get the desired word ot number?

    What have you tried? You don't know how to search a String for another string after 5000 posts???
  5. VS 2017 Re: Print specific data from data grid view, and auto print from scan gun-

    OK, yes, I have used that section of software before. That is where you append CR or whatever or replace a character. I am not sure how you would get it to parse out your fields and print a label for...
  6. VS 2017 Re: Print specific data from data grid view, and auto print from scan gun-

    Not sure what you are referring to by the "modify data" section. I think you must be referring to something in Zebra scanner software so, no, I haven't used that before. Can you take a screen shot...
  7. VS 2019 Re: Sending Live Data Out of Serial Port (Data is not Updated by itself)

    Of course you do since that is how you programmed it. Is there anywhere else other than SendBtn.Click that you do SerialPort1.WriteLine?

    If you wanted something to happen on a defined interval,...
  8. VS 2017 Re: How to alter VB.Net Naming Standards

    The reason I do it i00's way also is so all controls of similar type are grouped together in the IDE drop downs so I can find the one I want faster. The main exception is labels that are only for GUI...
  9. VS 2017 Re: Print specific data from data grid view, and auto print from scan gun-

    If the scanner and printer are both being run through your program this should be quite easy. As jdc2000 mentioned, you can append a suffix if needed to know when you receive a complete scan, and si...

    VS 2017 Re: Execution Timeout Expired

    Is your program really just sitting there for 30 seconds until timing out with that error? Once you get the error, does your program eventually recover or stay locked up? I would suspect something...

    You won't learn as much if you don't engage further.

  17. VS 2017 Re: Paint datagridview cell value based on value

    FWIW, you should have Trimmed the value. You'll note it was complaining about a single space (" "), but you were testing for an empty string (""), which is clearly not the same value. Glad you got it...

  20. VS 2017 Re: Use form as message box and then continue with code when it close

    Agree with John that you have no issue. The code in your routine will stop once you call ShowDialog and continue once frmSelection has been closed. Of course, if it is relevant, be sure to code for...
  21. Re: microSD card error message about how the disk is write protected fixes ?

    If you are using an adapter with a lock switch then turn the switch off. If a mobile device locked it, you'll need to put it back in that mobile device and unlock it first.

    Are you by some chance using an adapter that has a lock switch on it? Did this card come from a mobile device that may have locked it?
  26. Re: Why do I set a static IP in my computer without network ?

    Sounds like there must either be conflicting IPs that just aren't being reported or the networking stack on those PCs is corrupted somehow.
