Hi,
I have just started working on the NI labview...i had a problem that when i changed the bitrate using CAN interface create-->CAN SDO create-->CAN write.after that i am not able to communicate with the device with the new bitrate....i have seen a few similiar forums, which talks about object and port handles as an solution of the problems..
As
forums.ni.com/ni/board/message?board.id=30&thread.id=3405......
So i want ask that is this object and port handles....

Thanks your code.
I try the code you posted, It still no work, I found you has improved the "Get data.vi",It works better,but the second frame still no shown.
I used the NI CAN monitor in MAX to monitor the CAN bus,there is no second frame shown in the monitor,See attach pictures.but It shown in the Vector CAN monitor and the code call the Vector DLL.
Have a great day.

What are SERIALLY_REUSABLE and RESTRICT_REFERENCES pragmas, when can used?

Hi everyone,
I have recently joined in Discussion forums and feeling very excited to read blogs.
My question is about SERIALLY_REUSABLE and RESTRICT_REFERENCES pragmas.
what are these pragmas and when can we use them?
It would be greatly appreciated if anyone can answer this.
Regards,
Sachin Jaiswal

Go to http://tahiti.oracle.com, type in your searchwords, choose the database versions you are using and read the results.
e.g.
serially_reusable version 11.2
restrict_references version 11.2
Also this is not really related to forms, so for this type of question the SQL and PL/SQL forum might be more apropriate:
PL/SQL
but as you can see looking up in the documentation brings you answers to your questions in no time ;)
cheers

You have a Puerto Rico address on your account ? From a quick search I've found one site from somebody in Puerto Rico that includes a screenshot for an app receipt showing tax of 7 cents added to a 99 cent purchase. Are you able to view the purchase history on the account that you've been using, and see what prices show on them (e.g. if the store's listed price or price plus tax) : Store > View Account menu option on a computer's iTunes, then 'see all' link next to the Purchase History section.

0.41GB of my iPod Touh 4G' is taken up by something called 'Others'. What are 'Others' and can they be deleted or are they an essential part of the iPod and embedded in it? If not essential how do I go about deleting it to enable me to add other pictures

0.41GB of my iPod Touch 4G's capacity is taken up by something callked 'Others'. What are 'Others' and will it be o.k to delete them? If so how do I go about doing it as there is no trace of a file on either iTunes or my iPod?

Other content is typically miscellaneous data used by applications you have installed - could be save data (e.g. for games), or documents you've created. There's no easy way to determine precisely what it is, but the only way to clear it is to either delete it from within the respective application, or remove the associated application altogether - neither of which are typically practical.

What are the different ports required to Deploy(Run) an application in NWDS

Hi all,
We have a issue here in deploying our application in NWDS. As we are accessing our servers(from another country) thru firewalls in between, most of the ports are blocked for security reasons,henceforth, we are unable to deploy our application in NWDS.
Initially port 3601 was blocked, now its open.when i try to deploy my application , it prompts for a SDM password, after i enter it , it gives me error saying it can't process thru 50018 port.
So my query is , to build,deploy and run or debug a application in NWDS what are the different ports that needs to be accessable ?( so that i can tell my basis guys that all this specific ports need to be opened )
(Note: will the SDM port, debug port,Http port be enough to deploy and run an application)
Need your help on this
Regards,
Vijay

Hi Arun,
Thanks for your reply, as you told port 3601, its already opened. I didnt understand about the 3200,3300,3299. Can u be more clear about why each of this port is used for? ( bcoz i need to give a reason to my Basis guys,what each port is for)
Hope this Log details of the error that I get here helps you:-
Settings
SDM host : "ServerName"
SDM port : 50018
URL to deploy : file:/C:/DOCUME1/abap1/LOCALS1/Temp/temp22390Welcome.ear
Deployment exception : Server "srvName" did not accept login request as admin on port 50018. Details: ERROR: Could not establish connection to server "srvName" at port 50018: "srvName"
Inner exception was :
Server "srvName" did not accept login request as admin on port 50018. Details: ERROR: Could not establish connection to server "srvName" at port 50018: "srvName"
appreciate your valuable inputs.

What are valid and invalid email address characters

What are valid and invalid email address characters in Exchange 2010, for example can you have Conan.O'[email protected] is there a document that shows the valid and invalid sysmbols?

Hi
The format of email addresses is
local-part@domain where the local-part may be up to 64 characters long and the
domain name may have a
maximum of 253 characters - but the maximum 256 characters length of a forward or reverse path restricts the entire email address to be no more than 254 characters.[1]
The formal definitions are in RFC 5322 (sections 3.2.3
and 3.4.1) and RFC 5321 - with a more readable form given in
the informational RFC 3696[2]
and the associated errata.
Local part
The local-part of the email address may use any of these
ASCII characters
RFC 5322 Section
3.2.3:
Uppercase and lowercase English letters (a–z, A–Z) (ASCII: 65-90, 97-122)
Digits
0 to
9 (ASCII: 48-57)
Characters
!#$%&'*+-/=?^_`{|}~ (ASCII: 33, 35-39, 42, 43, 45, 47, 61, 63, 94-96, 123-126)
Character
. (dot, period, full stop) (ASCII: 46) provided that it is not the first or last character, and
provided also that it does not appear two or more times consecutively (e.g. [email protected] is not allowed.).
Special characters are allowed with restrictions. They are:
o
Space and
"(),:;<>@[\] (ASCII: 32, 34, 40, 41, 44, 58, 59, 60, 62, 64, 91-93)
The restrictions for special characters are that they must only be used when contained between quotation marks, and that 3 of them (The
space, backslash \ and
quotation mark " (ASCII: 32, 92, 34)) must also be preceded by a backslash
\ (e.g.
A quoted string may exist as a dot separated entity within the local-part, or it may exist when the outermost quotes are the outermost characters of the local-part
(e.g. abc."defghi"[email protected] or
"abcdefghixyz"@example.com are allowed. Conversely,
abc"defghi"[email protected] is not; neither is
abc\"def\"[email protected]). Quoted strings and characters however, are not commonly used.
RFC 5321 also
warns that "a host that expects to receive mail SHOULD avoid defining mailboxes where the Local-part requires (or uses) the Quoted-string form".
The local-part "postmaster" is treated specially - it is case-insensitive, and should be forwarded to the server's administrator. Technically all other local-parts
are case sensitive, therefore [email protected] and [email protected] specify different mailboxes. However most organizations treat uppercase and lowercase letters as equivalent, and also do not allow use of the technically valid characters
(space, ? and ^). Organizations are free to restrict the forms of their own email addresses as desired, e.g.,
Windows Live Hotmail,
for example, only allows creation of email addresses using alphanumerics, dot (.), underscore (_)
and hyphen (-).[3]
Systems that send mail must be capable of handling outgoing mail for all valid addresses. Contrary to the relevant standards, some defective systems treat certain
legitimate addresses as invalid and fail to handle mail to these addresses. Hotmail, for example, refuses to send mail to any address containing any of the following standards-permissible characters:
!#$%*/?^`{|}~
Domain part
The domain name part of an email address has to conform to strict guidelines: it must match the requirements for a
hostname,
consisting of letters, digits, hyphens and dots. In addition, the domain part may be an
IP address
literal, surrounded by square braces, such as jsmith@[192.168.2.1], although this is rarely seen except
in email spam.
Examples
Valid email addresses
<tt>[email protected]</tt>
<tt>[email protected]</tt>
<tt>[email protected]</tt>
<tt>much."more\ unusual"@example.com</tt>
<tt>very.unusual."@"[email protected]</tt>
<tt>very."(),:;<>[]".VERY."very@\\\ \"very"[email protected]</tt>
Invalid email addresses
<tt>Abc.example.com</tt> (an @ character must separate the local and domain parts)
<tt>[email protected]</tt> (character dot(.) is last in local part)
<tt>[email protected]</tt> (character dot(.) is double)
<tt>A@b@[email protected]</tt> (only one @ is allowed outside quotation marks)
<tt>a"b(c)d,e:f;g<h>i[j\k][email protected]</tt> (none of the special characters in this local part
is allowed outside quotation marks)
<tt>just"not"[email protected]</tt> (quoted strings must be dot separated, or the only element making
up the local-part)
<tt>this is"not\[email protected]</tt> (spaces, quotes, and backslashes may only exist when within
quoted strings and preceded by a slash)
<tt>this\ still\"not\\[email protected]</tt> (even if escaped (preceded by a backslash), spaces, quotes,
and backslashes must still be contained by quotes)

What are ROWID and ROWNUM? Are they stored in database and where?

Hi All,
can anybody please answer this question
What are ROWID and ROWNUM? Are they stored in database and where?
Thanks,
Srini

ROWID can be thought of as a pointer to the physical location (on disk) of the (table) row.
From a ROWID value, Oracle can extract the file, block-within-that-file and offset-of-the-row-within-that-block. Using these, Oracle can directly access a disk block to retrieve a row.
ROWNUM is a just sequence number of a row within a result set of a query.
As said by other repliers, both are not stored. They are 'constructed' when you reference them inside a query.

What are high and low values in sharepoint 2013 user permissions?

So I hit this api:
http://win-a3q7ml82p8f/sharepoint_site/_api/web/roledefinitions/
And got the different high and low values. But I am not clear with what they mean:
For eg:
High: 176, Low: 138612833
and
High: 176, Low: 138612801
So for different values of Low how does it change the permissions?
For 176 its binary is 10110000. So looking at this table here: http://www.dctmcontent.com/sharepoint/Articles/Permissions%20and%20Mask%20Values.aspx
I can understand that 176 would mean the following set of permissions:
DeleteVersions
OpenItems
ApproveItems
But what's confusing me is, that user has OpenItems permissions but not ViewListItems permission? Am I wrong in understanding this?
Also how does the value of Low change the overall user permissions?
Note: I looked at this answer: http://social.msdn.microsoft.com/Forums/sharepoint/en-US/9d6df168-e8f5-4323-8c34-0646c03eff68/rest-api-what-are-high-and-low-in-effectivebasepermissions-and-getusereffectivepermissions?forum=sharepointdevelopment
But honestly I cant understand what that means. Can someone help please?
