Hi everyone,
I am sending a lot of small data packets via USB and everytime LabView reads or writes something, the I/O windows pops up. This is annoying me, is there any way to turn it off?
Regards,
Pedro

I have no idea what you mean by I/O window. Attach your code.

Good morning,
The standard input/output window of LabView. The 'X' in the top right corner is greyed out, so one can't close it, only minimize. But everytime data is sent or received, it jumps right back to its prior position.
Attachinng code isn't possible, because I call an external dll to communicate via USB. Maybe this is the problem?

Sounds to me like your VI settings are incorrect. For your IO Popup, Change the Window Appearance settings so that Show Front Panel When Called is unchecked. For your grayed out "X", make sure allow user to close window is checked.

What "standard" input/output window of LabVIEW? I've never heard of such a thing. Are you sure the DLL you're calling isn't doing this? Especially since you said it happens when you send/receive data, which you do with the DLL.

Please post a jpg image of the "standard input/output window ".
I, like Saverio have never seen the "standard input/output window ".

As far as I know there is no "standard input/output window" in Labview.
Probably the pop-up is due to the DLL.
What's the USB device you are writing/reading from? And the DLL?
As already pointed out, a screenshot would be helpful.

Hey everyone,
thanks for your efforts so far. Sadly, it did not help. Through customize window appearance, I can only change the VI itself, which already is set to being closeable.
I attached a screenshot of this I/O-window and am almost certainly sure that is has something to do with that DLL I am invoking, since nobody of you has experienced similar occurences.

Pedro
EDIT: The device is a HID in developement, can't say more about that, since it is not on the market yet, sorry. The DLL is a HID api, with a wrapper made by a colleague of mine.

Talk to your buddy about that.
That looks like the standard I/O window for C where things like "printf" show-up durring trouble shooting.
I don't think it can be killed in a straight forward manner from LV without having to resort to using Window system calls to get a handle to the window and hiding same.

Thanks for all the input. I'll have a talk with him and see, if we/he can fix that.
