Monthly Bugs, November 2012

Continued from the October 2012 bugs thread

 The posting rules are as always:

• Each post here should only contain a brief description of a bug, together with a link to the thread where it is being discussed.
• One post/bug!
• One bug/post!
• No discussion of bugs. All discussions of a bug must take place in the original linked thread.

I haven't reported anywhere and I don't have a proof either.

In LabVIEW 2011 initially the quick launch and search was very quick ( Compared to earlier versions) but now it is taking more than 20 seconds to launch.
 My PC doesn't have anyother big software and only LabVIEW is running. Is there any patch on this or anybody else has faced this problem can share.

P@anand,

The established procedure for this board is to start a new message in a regular forum.  Once there is a discussion and there is some consensus that you have a bug (a CAR# assigned by an NI employee certainly qualifies) then you post a message here with a brief description and a link to your original message thread.

What you have posted here is an anecdote, and even you say you have no proof.  You haven't established there is any bug.  Actually, 20 seconds to load LabVIEW doesn't seem that long in my experience.

If you have any more comments, please start a new message thread in the LabVIEW forum.

Serial Bug:

When reading binary data the property node "Serial Settings:Number of Bytes at Serial Port" shows a wrong number of bytes when one or more bytes has the value of xFF. For each byte on the bus containing xFF the #bytes is incremented by one.
So when the bytes 10,20,30,255,112 are sent to the computer, LabVIEW's #bytes shows 6 bytes. So reading 6 bytes will time-out after which 5 bytes are received with the values as sent. When the bytes 10,20,30,254,112 were sent,  everything is OK.

This was done on MacBookPro MacOsX10.7.5 and VISA5.2.0 LabVIEW2009SP1/2012

Scott Hannahs was able to reproduce it with Mac OS X 10.6.8 / LabVIEW 8.5.1 / VISA 5.20

seems to be a VISA bug/feature

Regards,
Paul

Paul,

Did you read the message immediately above the one you just posted?  Did you read the message at the top of the message thread?

This thread is for providing a repository of links to confirmed bugs.  It is not here to report new bugs.  You need to post your message in the LabVIEW forum.  Give people a chance to discuss it.  More often then you might imagine, people will claim they found a LabVIEW bug and it turns out they were just doing something stupid, or didn't read the help files for a function correctly.  For all we know, that might be your situation.

Spoiler

Why is it that after months and years of having very few problems with the bug threads, two different people on the same day decide to not bother reading the rules of the thread?

[PaulRijk]

Sorry. You're right.

Listbox property "Top Row" only excepting values smaller than 32768 but there can be more entries in a listbox and the data type of the property is I32. Can be found here.
