A button dialog box appears intermittently

Has anyone encountered any instance where they ran of code that contains a call to a Dialog.vi button and didn't do not display dialog box?

I write the code at present which is to launch a "Sample Communication Controller.lvclass" player. I tried to make calls for dialogue in instances overridden "Pre launch Init.vi" and "Core.vi actor". In both cases, whenever I run the actor often the dialog box does not appear. The code below illustrates my second attempt, when I tried to put the call on "Example of Communication Controller.lvclass:Actor Core.vi" (not done as an extract VI because the extract VI feature is buggy).

I rolled my own logging system and use I think 'Example Communication controller begins!' is recorded systematically whenever the player is launched, if yes or no dialog box appears.

Flat sequence structure is temporary and just an attempt to see if the data dependencies change has an effect.

Just a long shot, but the dialog box button requires root loop. If something else is hogging the loop of the root, I could see what is happening, although I expect the code to hang.

A simple test would be to replace the dialog box a button with a dialog of three buttons (see link for details).

    bastyav,
    We use the exact and some error message in more detail on the issue.  This problem occurs with any file on the disk or only some of them?  You are logged as administrator?  Has anything changed recently (hardware or software)?

    The first thing I would say to run a Virus scan and malware.  If you do not have an antivirus program, then you can get one here: http://www.microsoft.com/Security_essentials/

    If there are no problems found then not try the following steps:
    Run the following commands.

    Chkdsk /r

    .. .all dialog box appears on screen is covered in "' so I can't put passwords or addresses of sites and if the sound is on a morse codes like noise appears with the comma...

    The character you are evidence is a single quotation mark or tick rather than a comma, but the character you see in reality is probably an asterisk in a mask the password text box. In both cases, the problem remains the same.

    You have a key stuck on your keyboard which instantly fills any box entry with the typed characters, they are ticks or asterisks. The only audible ringer is a normal computer error indicating that the keyboard buffer is full, but entry continues, once again an indication of a stuck keyboard key.

    Try another keyboard. It may be possible to launch a key by a sharp tap, but the problem will probably persist in the future. I hope that you don't talk about your laptop.

    I got the last part of what you wanted, which was simply not the message

    The key is that you have to allow this program through your windows firewall.

    Go to your look for the windows Firewall Control Panel,

    There should be a list to allow a program through windows firewall, look at the top left.

    If you feel safe doing this, vlc is not one that I would feel safe with, but to you, it has a function to browse to find the program to be added to your trusted list or access through your firewall.

    Still, it may give you a warning but could release the message?

  • Prompt dialog box appears only not on BBOS 10, work on OS2.1

    Basically, my application after initialization all BPS lib and screen context, etc., creates a prompt dialog box, then goes into the loop of the main application.

    It works very well with OS2.1 on the PlayBook. Dialog box appears and gets the user to enter an IP address. Close on cancel and continue on "Connect".

    This does not at all with BBOS 10. App opens and is here. Dialog box does not appear. Changed to appear on swipe_down. Swipe_down of event triggers, but the dialog box does not appear.

    Is there something that has changed between OS10 and 2.1? It might have something to do with the dialogue group?

    Tried to place a dialog_group_id, but did nothing else. just makes work less in 2.1.

    During the installation of the screen, you must create a group of windows with screen_create_window_group() immediately after creating the window with screen_create_window().

  • Dialog boxes appear off the screen

    Hello, I have problems with dialog boxes in Illustrator CS6.

    Dialog boxes are appearing in various different locations rather than a central location on the screen...

    For example: the Save dialog box appears half off the screen towards the lower right section of the screen. Various other boxes appear at the top left, top right. All dialogs are mobile, so I can reposition in the Middle, but the next time I used appear where they were not at the Center.

    I work on both a 13 "macook pro separately and with and 27" apple screen attached. Dialog boxes are visiable on 27 "screen, but often in odd places.

    Is there a way I can reset their position?

    I tried reseting all the dialogues, trashed the preferences in the preferences in the folder of the library on the computer but no luck. I'm puzzled.

    Any help would be appreciated...

    Thank you

    nosbornf,

    It is important that Illy is closed when you reset the preferences.

    Try the following (you may have tried / some of them already) and see if it helps:

    (1) close Illy and open again.

    (2) restart the computer;

    (3) close Illy and press Ctrl + Alt + Shift / Cmd + Option + shift at startup.

    4) move the folder with Illy closed;

    (5) browse and try the relevant among other options;

    Even worse, you can (if all else fails and no best answer appears):

    (6) uninstall, run the cleanup tool and reinstall.

    What version of the game you are using, retail disk, steam or other?

    Latest games will automatically install .NET if they require it, but if you have not updated to

    Microsoft .NET Framework version 4.5, try installing that.

    Restart after the installation.

    Download Microsoft .NET Framework 4.5 of the official Microsoft Download Center

    Also, there may be some Windows updates .NET security updates installed.

    Installation folder of many games that use of .NET will have an installer, dotnetfx in a subfolder in the games, and you can also install from that.

  • When I connect my Nikon camera to my PC no AutoPlay dialog box appears?

    When I connect my Nikon camera to my Pc via the USB, nothing DO if POSTER?  Windows help suggests the AutoPlay dialog box sn will appear automatically, it doesn't!

    I tried to make a connection by default, but still nothing appears on the screen that I can work then of?

    Personally, I think that autoplay should be abolished, but that's just me! Have you checked to see if your camera is projected in 'Computer'? If so, you can copy and paste or cut and paste the files where you want them to be. The SIM card in the device should appear as any other folder.

    I hope this helps.
