How can I retrieve the col data size and Null information from table using labview connectivity toolset

Hi, there,
I am wondering how to get the table information by labview database
connectivity toolset. The table list vi comes with the toolset can get
only col name, data type and data size. And I found the the data size
always gives back -1, even though it is a string type. Do somebody has
some idea about it?
Thanks.
JJ

JJ,
Go into the diagrams of the DBTools List Columns and DBTools Get Properties respectively. When you inspect this diagram, you will see the raw ActiveX properties and methods called to get the size information. The value of -1 means the requested recordset is already closed. This is the sort of thing that is controled by the driver (ODBC, OLE DB, Jet, etc) you are using. Notice that you can right click on the property and invoke nodes and get more information about these specific items directly from the ADO online help.

How can I check the expiration date of a Certificate Keychain from terminal?

Hello, I am writing a bash script to alert me when my corporate certificates are about to expire. How can I check the expiration date of a certificate in keychain? I'm running Mac OS 10.6.8 on a newer MacBook pro with full admin rights.
Specifically I will be checking three certs: a Root Authority, Issuing Authority, and a user cert (Identity).
I was exploring the Security and Openssl command line tools. But I can't seem to get the info I need.
Any recommendations would be appreciated.
Thank you!

Anyone?

How can I change the legend of a plot in an excel chart using LabView?

Hi,
My question is:
I create a chart in Excel with LabView7 using ActiveX. There are 4 plots in one chart. How can I rename the legend (the name) of each plot with LabView?
Thanks.

Use the SeriesCollection(1).Name function. In LV, wire up the following:
_Chart into Method SeriesCollection (index = 1 to 4)
Cascade into Variant to Data (wire type Excel.Series)
Wire Series into Property Name, Write the string

How can I remove the "Show Data in Single Pane" button from ui:table?

All I have is paginate selected in table properties.

Hi,
Thank you for explaining it so clearly. After enabling the pagination, go to the properties sheet for the table. Under the Appearance section there is a property called paginateButton. Uncheck this property and you will have pagination enabled but not the Show data in a single pane button.

How can I hide the tool data box?

How can I hide the tool data box that reads out the loction in Photoshop CS6?
It appears when I move a layer or change the size.
It is very distracting and totally useless for me (I'm an artist - not an engineer).
I can't find a setting to remove that black box. I hope there is a way to make it go away...
Thanks!

It sounds like your talking about the transformation values.
In the photoshop preferences under Interface you can set Show Transformation Values to Never

I lost my macbook pro and i just got a new one. how can i retrieve the pictures taken with photo booth(old laptop) to my new laptop?

i lost my macbook pro and i just got a new one. how can i retrieve the pictures taken with photo booth(old laptop) to my new laptop?

Well if you don't have the laptop to get the storage drive out of it, and you don't have any previous backups how do you expect to get the photo's?
PhotoBooth is just a program, it stores the files on the computers storage drive, if the computer is lost so are your photo's.
There is nothing you can do to delete or retrieve them using your new computer unless you stored them online someplace.
DId you save them online? iDisk or something else?
I don't use such services because my data is mine and not theirs to snoop through, so if your looking for that sort of help I can't assist you any.

How can i get the meta data from database?

Hi, all java and db experts,
I need to write a tool to generate java file which will be used to hold the resultset of a stored procedure of Oracle. Is there any API call or tools to connect to db and then get the meta data of the return cursor instead of reading stored procedure definition on my own?
Please help, thanks a lot.
Hanna

if i execute a Oracle stored procedure, the resultset of a cursor is returned. It's easy to know the meta data at the runtime.
However, could i get the meta data about the resultset of a cursor before runtime? Such as by connecting to the database and ask it about meta data of a specified stored procedure?
Is it feasible?
DatabaseMetaData dbmd = conn.getMetaData();
ResultSet rs = dbmd.getProcedureColumns("", "%", "SP_NAME", "%");
while (rs.next()) {
String colName = rs.getString(4);
int colType = rs.getInt(5);
int colDataType = rs.getInt(6);
int colPrecision = rs.getInt(8);
int colLen = rs.getInt(9);
int colScale = rs.getInt(10);
long defaultValue = rs.getLong(11);
But what i get is a list of stored procedure parameters. In oracle, cursor is IN OUT parameter . How can i get the meta data about the resultset of cursor?

How can we retrieve the Payload information from B2B

Hello,
We are trying to send the payload information back to the client for a failed BPEL Transaction from B2B's b2b_instancemessage view. We are enqueing messages to IP_OUT_QUEUE using BPEL. We see the payload coming correctly in the B2B Business Message Reports. But we don't see the payload coming in the b2b_instancemessage view for failed B2B transactions. How can we see the payload in b2b_instancemessage view for failed B2B transactions as well? or How can we retrieve the Payload information from B2B?
Any help is greatly appreciated! Thanks. - Sam.

I am not sure about the PDK API to get the group name. But using LDAP API its easy to get the User Group.
If you find the answer to get the group name using PDK API, Please update in forum. It will really help others.

I have made a burn folder with photos exported from I-photo. It now shows in information, that the date is created and modified is different from the original digitized date. How can I get the original date to show in the info from Finder?

The Finder reports File information. The date and time of the photo are in the Photo's Exif metadata. The Finder has no awareness of this. All photos apps on any system do.

i have deleted all contacts in icloud but still have them on my iphone (which is backed up as well to iTunes) how can i restore the iphone data to the iCloud so it will resend it to my mac book and iPad? I have switched my iphone to airplane mode so it is not connected to the internet and so icloud can not wipe it at the moment.
thanks roy

There's a menu choice (I think under "Files") that lets you sync purchased items on a device back to itunes. Look for that.
iCloud does not store music. If you want to do that you'd have to subscribe to itunes Match, but to get music to the match servers, you need the music in the itunes library on your computer.

How can I set the insert date to auto update in Pages 5.2.2

how can I set the insert date to auto update in Pages 5.2.2
I am attempting to have the date in header auto update in a Pages file.
I can insert it, but where is the AUTO UPDATE selection
OS10.9.4
thank you

Apple never included the auto-update feature for dates in Pages v5.2.2. You would have to single-click the date, and deliberately update it.
If you have Pages ’09 v4.3 in /Applications/iWork '09, then it will allow you to configure auto-update of the date field. Right-click on the date, set the format, and click the selection for automatically update on open.

When importing a CD, the CD Lookup Results dialogue box came up and I choose the wrong CD title. Now iTunes is importing a different song list than the one on my CD. How can I retrieve the CD Lookup Results to choose the correct title?

When importing a CD, the "CD Lookup Results" dialogue box came up and I choose the wrong CD title. Now iTunes is wanting to import a different song list than the one on my CD. I've shut down my computer and opened iTunes from the hard drive Program Files and tried to import the CD again with the same problem. How can I retrieve the "CD Looup Results" diaglogue box to choose the correct CD title to fit the song list on my original CD?

You might also be able to do it without importing the songs again I think. Just highlight the tracks, right click them and choose "Get Track Names". This feature only works on CDs that were imported via iTunes.

Hi,
You can use SimpleDateFormat class under java.text package.
SimpleDateFormat formatter = new SimpleDateFormat("dd-MMM-yy h:mm a z", new Locale());
//formatter.setTimeZone(timezone);
String dateTime = formatter.format(new Date());
