Delta t do not update using write in the measurement file
I write data to a file that is collected with a dt = 0.005 sampling interval (but no hardware DAC. I would like to save the data in a file LVM with a column, the timestamp and the second data column, and I use the Express VI 'Write in a file measure' in the following Labview code snippet:
The value of the local variable dt is 0.005. The delta T is saved in the saved file, but the timestamps don't change the initial value of o, o:
What Miss me?
Thank you

I wouldn't really call it a workaround solution. This is the expected behavior.
Build and write like a table and your waveform will be saved correctly.
If you are going to write a point at a time, all you have to do is to keep track of what you want to use when you build your unique point to t0 and wiring waveform.
EDIT: Is the column name 'Untitled' bug your client at all? It would have upset me. You can fix it by set the attribute of waveform for "NI_ChannelName."

"Not able to write to the configuration file" when config editor in the admin tab
Hi guys,.
I have install OBIEE 10.3.3.4 on a GNU / linux RH (with OS user obiee) and Oracle Application Server 10.1.3.1 on the same box (with OS user oraias).
When I want to change some settings in the admin tab of BI publisher (administrator/administrator under the name of login/pass) and click "apply."
I get the error "could not write to the configuration file. Once I changed the configuration to 777 properties, the error is still there. And I also try to change the SECURITY MODEL to the MEO, but still no use.
I did a test, for example, when I change something in the admin - JDBC - Oracle BIEE and apply then I got the error. If I update xmlp/DataSource/datasources.xml manually, the change can be seen after that I opened the admin of page - JDBC - Oracle BIEE. That means I have find the right file and the file access properties is ok.
Other parameters such as the Scheduler Configuration, I had the same error when apply. But the "Test connection" and "Installation diagram" function.
Can someone give me some advice on this? Thank you
Scott
Published by: Typhoon on March 20, 2009 12:59 AMIn what way is your xmlp? You are absolutely sure that the user of the OAS (oraias) can write to this file? If you have used another user for OBIEE then your will need to change the owner of the file or put them in the same group, and change the file permissions.

list box given to the .csv file using write on the worksheet File.vi
Hi, I use the write on the worksheet File.vi to write data multicolumn ListBox to the .csv file. If I do record from Excel, the pop-up window shows as an attachment. And data listbox are too different. I want the data displayed in the first line not the second row (third photo).
Thank you for your help.
Before making your Save As in Excel, change the cell formatting of number. This should avoid the scientific notation conversion before you re-register.
Or just use Notepad to display the file instead of Excel.

usefulness of reading the measurement file express vi
Hello
I found reading file express vi measure in LV7.1 does not read from the beginning of the file when you run it the second time. Instead, it resume from where it left off last time. Usually, the user would read the entire file measure each time. So when you try to read the second time, it will show an error window saying that it has reached the end of the file (because he was reading the entire file first).
I wonder how useful to resume from the last stopping point is? Is there a way to start over each time that the VI excute it?
I'm sure that's how reading file measure works 90%. Whenever she is called in a single run of the application, it will start off the coast where it was stopped. You will need to work with the low level screw to get what you want to do.
This Express VI works in a similar way the screws and the following functions:
Open/create/replace file
Read text file
Read binary file
Read the spreadsheet file
File dialog box
Scan to fileAnd, you can always use the node to set the file Position to set the position at the beginning of the file.

What can be?
Well, you very probably not a lot of space on the left under/Home.
You can move to another location that is located on/home/oracle/orInventory the / partitioning of the partition where you probably have more space left if you used the default value.
For example, as a root user:
mkdir/U01
MV/home/oracle/oraInventory/U01
Update /etc/oraInst.loc and replace
inventory_loc = / home/oracle/oraInventory
with
inventory_loc = / u01/oraInventory

Write to the spreadsheet file (how to start new lines)
I'm reading signals from a hardware device and try to write it in several columns using Scripture in the spreadsheet file every few seconds.
My problem is every time a new signal comes in, my program seems to overwrite the previous signal when writing to file, when (say after 2 minutes), I go to check the written file, it shows only 1 row of information. How can I fix?
Part of my VI and the output file is attached.
If the program segment shown in your picture is inside a loop, then the section header write overwrites the file each iteration of the loop. So, you see only the data for the last iteration. Solution: Move portions header to write and write the names of channel out of the loop or put them in the case of structures that run only when you want a new file or new channels.

I created a zip of a directory tree file using "send to...". "'Compressed (zipped) folder '. When I try to "extract all...". ", he asks me a password for some (not all) of the files in the zip file. I does not have a password for the zip file. I didn't even know it was possible to have a password on a specific file in a zip! Needless to say, I can not give the password because I don't know what it is.
I tried the following:
(1) created with "send to...". "Excerpt from" compressed (zipped) folder ', with 'extract all... '. ». Result: request password.
(2) created with "send to...". "" Compressed (zipped) folder ", extract with 7 - zip. Result: No password query. All the files extracted intact.
(3) created with 7 - zip, extract with "extract all...". ». Result: request password.
(4) created with 7-zip, extract with 7 - zip. Result: No password query. All the files extracted intact.What I find most interesting is (3).
Does anyone have an idea of what's going on? Is there some kind of security on the files meta-data that could / should cause this behavior?
