Hi Experts,

How to read the date and time information of a file by labview

how to read the date and time information of a file by labview? for example, created time and modified time.
Solved!
Go to Solution.

if you need to know the last modification date of file:-
"Functions->File I/O->Advanced File Functions->File/Directory Info.vi"
This vi returns the value of file's last modification date. This is returned as U32 number. To see it in MM/DD/YY format you must create the indicator, right-click on it and select "Format & Precision" item from drop-down menu. Then select "Time and Date" format there.
Thanks as kudos only

How to read the data from an internal table,when column names are known

Hi All
I have a specific requirement. I got an internal table with many fields (let it be my_tab). Some of the fieldnames (column names in internal table my_tab) are stored in separate internal table(let it be my_fields).
I need to store/read data corresponding to the fields (whose name is stored in my_fields) from my_tab.
I am able to build dynamic table (referred by field-symbol) with respect to the given field names in my_fields.
But i am unable to read the data corresponding to the fieldnames from my_tab.
Please provide me some pointer in this regard.

The problem is in the delimiters in your text file. By default, Read From Spreadsheet File.vi expects a tab delimited file. You can specify a delimiter (like a space), but Read From Spreadsheet File.vi has a problem with repeated delimiters: if you specify a single space as a delimiter and Read From Spreadsheet File.vi finds two spaces back-to-back, it stops reading that line. Your file (as I got it from your earlier post) is delimited by 4 spaces.
Here are some of your choices to fix your problem.
1. Change the source file to a tab delimited file. Your VI will then run as is.
2. Change the source file to be delimited by a single space (rather than 4), then wire a string constant containing one space to the delimiter input of Read From Spreadsheet File.vi.
3. Wire a string constant containing 4 spaces to the delimiter input of Read From Spreadsheet File.vi. Then your text file will run as is.
Depending on where your text file comes from (see more comments below), I'd vote for choice 1: a tab delimited text file. It's the most common text output of spreadsheet programs.
Comments for choices 1 and 2: Where does the text file come from? Is it automatically generated or manually generated? Will it be generated multiple times or just once? If it's manually generated or generated just once, you can use any text editor to change 4 spaces to a tab or to a single space. Note: if you want to change it to a tab delimited file, you can't enter a tab directly into a box in the search & replace dialog of many programs like notepad, but you can do a cut and paste. Before you start your search and replace (just in the text window of the editor), press tab. A tab character will be entered. Press Shift-LeftArrow (not Backspace) to highlight the tab character. Press Ctrl-X to cut the tab character. Start your search and replace (Ctrl-H in notepad in Windows 2000). Click into the Find What box. Enter four spaces. Click into the Replace With box. Press Ctrl-V to paste the tab character. And another thing: older versions of notepad don't have search and replace. Use any editor or word processor that does.

FCP error message: Unable to read the data on your source tape!

Hey,
So I have been editing on the MacPro now for over a year and I have never seen this message before...the message reads:
_*"Capture encountered a problem reading the data on your source tape. This could be due to a problem with the tape."*_
Has anyone got this message and could help me out please? I need to edit these tapes A.S.A.P.
Thank You,
Erick

why would it start a month later giving me problems instead of when it was updated?
That is a good point. Anything change since the time it worked to when it didn't? How about trying another firewire cable. Those can go south without notice, might cause this.

How to read the data in excel sheet

Dear sir,
How to read the data in excel sheet when i recieve a data serial communication... ie i have store a data in excel such that
Cell A Cell B
A Apple
B Ball
C Cat
D Doll
when i recieve A from serial communication i have to display Apple, and when i recieve B i have to display Ball and so on..

Hi,
I would recommend you to have a look at the VI attached. It makes use of a VI named 'Read from Spreadsheet' to read the row and column data from the tab delimited excel file. The read data is then searched for the Alphabet specified and finally returns you the corresponding string. The test file used to validate the operation of the VI is also attached.
Trust this would help you solve the issue.

ITunes cannot read the data on my iPod touch

Just three weeks or so ago, I was able to use iTunes without any problems to put a few songs on my iPod Touch 2nd Gen. Recently, however, whenever I try to connect my iPod to iTunes via USB, I get an error message that says something along the lines of: "iTunes cannot read the data on xxx's iPod Touch. Go to the Summary tab and choose Restore to restore this iPod to it's original factory settings.". I don't know why it says this since my iPod is functioning normally. My iPod shows up on the left hand side of the iTunes window as "iPod" instead of "xxx's iPod Touch" like it used to. The only options I have are Check for Update (disabled) and Restore. Is there any way to fix this without restoring my iPod? And if I have to restore, can I do so without losing (or having to re-transfer) any of my data that hasn't been or can't be backed up? Please help and thanks in advance!
P.S. My iPod is in its genuine state: it hasn't been jailbroken or anything like that.

Unfortunately, I've already tried that. Also, here is a list of other things I've tried, but have taken no effect:
-Recharging, Restarting, Resetting, and Reconnecting my iPod Touch to my computer
-Restarting my computer
-Reinstalling iTunes
-Reinstalling all iTunes, Apple, and iPod USB drivers
-Updating the same drivers (but no updates were found)
-Using a different USB port
-Connecting to a different computer (doesn't work on my Toshiba laptop either, which is running the same OS and the same version of iTunes as my PC)
My backup plan was to copy the new songs to my iPod by pasting them through Windows Explorer. My iPod shows up as a portable device under My Computer - as always - but the only thing I can access is a folder full of the photos on my iPod. I think this is normal, but I can't do what I want to do! Do you (or anyone else) have any other good ideas? Remember, I really don't want to do a restore unless I absolutely have to.

How to read the data from a column that is in clob data type (but XMLdata)

Hi ,
I have a table XYZ which has a column RESPONSE_XML in clob datatype format.we can convert it to XMLTYPE(RESPONSE_XML) to read the data in XML format.
Now this is the DynamicXML schema file. Here I want to see all the COMMONNAME, ResourceDescribedby_VALUE into column_A, ResourceDescribedby_ResourceSpecCharacteristic_Name tags into column_B
How can I do that .. any suggestions please ..
Here is a sample XML:

you don't appear to have posted valid XML, so I can't reproduce using your example, but you will need to look at something like this:
select xtab.common_name
from your_table yt
      ,xmltable('/SearchResourceResponse'
          passing xmltype(yt.response_xml)
          columns
              common_name varchar2(20) path 'SearchResponseDetails/CommonName'
      ) xtab
;

How can I read the data type of a field in an MS Access database

I need to be able to determine if a field in an Access database is of a certain data type, and if it isn't, to change it to what it should be.
I can't seem to find any way of reading the data type of any field in any table - can anyone give me a metod of getting this info?
Thanks

Does <cfdbinfo> work for Access DBs?
You might be better off asking this on a MS Access forum. It's more of an Access issue than a CF one.
