How to write UDL file in Labview for Database connection

Hi
I am using SQL Server database. I am making connection with SQL by using UDL file. If I create Normal UDL file in windows and make connection it happens. I want to change or add some parameter Like database name. If I am changing this value by using labview, the file gets corrupted, and not able to make connection with SQL.
I want to create database by program. User should not create the database.
Kindly suggest me the proper solution.

It may look like a text file, but it's not a text file that uses plain-old ASCII. If you open it in Notepad you won't see anything obvious. You actually have to open the UDL file with a hex editor, and you will see the differences. Specifically:
The file starts with the header FF FE. This indicates Unicode. LabVIEW does not support Unicode.
Each characters is actually 2 bytes. Thus, the first character you see in Notepad is "[" (for the section start). In hex this is 05 for plain-old ASCII, but 05 00 for Unicode (which is what's actually in the file).
Thus, if you absolutely must write out the file using LabVIEW you will need to write it out in binary mode, inserting the 0x00 bytes, and the FF FE at the start.

Hi Dilpreet,
reading wav files is easy using the functions from the sounds palette...
For your other tasks you could use a seperate toolkit or do some programming on your own!

Why are you wasting your time coding from scratch using the PL/SQL Web Toolkit instead of the APEX framework?
From Re: how to write a file using mod pl/sql it appears that you are not using APEX, so a number of the approaches APEX offers are not relevant. You appear to be looking for a file download solution using the <tt>wpg_docload.download_file</tt> method, such as:
create or replace procedure download_file (
 p_filename in varchar2
, p_mimetype in varchar2
, p_content in out nocopy blob)
is
begin
-- Set up HTTP header.
-- Use "application/octet" as default MIME type.
owa_util.mime_header(nvl(p_mimetype, 'application/octet'), false);
-- Set the size so the browser knows how much to download.
htp.p('Content-length: ' || dbms_lob.getlength(p_content));
-- Filename will be used as default by the browser in "Save as..."
htp.p('Content-Disposition: attachment; filename="' || p_filename || '"');
-- Close header.
owa_util.http_header_close();
-- Stream the file content to the browser.
wpg_docload.download_file(p_content);
end download_file;

How to write text file in Shockwave?

Does anybody know how to write text file in Shockwave to
user's disk?
Thanks in advance.

Those Xtras can wreak to much havoc when used with the wrong
intent.
What you can do is write with setpref and store a list of
saves and the
saves itself seperatly. Then you'd have to build your own
save/open
dialog to let the user:
* pick a previously saved file to load or overwrite
* have the user type the name of a new file to save.
Only thing that remains is that the user cannot decide where
the files
are saved.

How to create backup file on itunes for ipod touch 4g game apps data? Is there a way to do it? I want to try an app on my friend's computer, but you can't add apps on another computer without having your own ipod's data being deleted. Thx for any help!

How to create backup file on itunes for ipod touch 4g game apps data? Is there a way to do it? I want to try an app on my friend's computer, but you can't add apps on another computer without having your own ipod's data being deleted. Thx for any help!
I want to know how to create a backup file (because I'm pretty new with itunes, and it's hard to use it for me still), how to store my app data/media/videos, etc. And how I can retrieve them back when I'm done with the app I tried on my friend's computer.
If anyone can help, it'd be great! Thank you so much!

Sure-glad to help you. You will not lose any data by changing synching to MacBook Pro from imac. You have set up Time Machine, right? that's how you'd do your backup, so I was told, and how I do my backup on my mac. You should be able to set a password for it. Save it. Your stuff should be saved there. So if you want to make your MacBook Pro your primary computer, I suppose, back up your stuff with Time machine, turn off Time machine on the iMac, turn it on on the new MacBook Pro, select the hard drive in your Time Capsule, enter your password, and do a backup from there. It might work, and it might take a while, but it should go. As for clogging the hard drive, I can't say. Depends how much stuff you have, and the hard drive's capacity. As for moving syncing from your iMac to your macbook pro, should be the same. Your phone uses iTunes to sync and so that data should be in the cloud. You can move your iTunes Library to your new Macbook pro
you should be able to sync your phone on your new MacBook Pro. Don't know if you can move the older backups yet-maybe try someone else, anyways,
This handy article from Apple explains how
How to move your iTunes library to a new computer - Apple Support''
don't forget to de-authorize your iMac if you don't want to play purchased stuff there
and re-authorize your new macBook Pro
time machine is an application, and should be found in the Applications folder. it is built in to OS X, so there is nothing else to buy. double click on it, get it going, choose the Hard drive in your Time capsule/Airport as your backup Time Machine and go for it. You should see a circle with an arrow on the top right hand of your screen (the Desktop), next to the bluetooth icon, and just after the wifi and eject key (looks sorta like a clock face). This will do automatic backups of your stuff.

How to load text file data to Oracle Database table?

By using Oracle Forms, how to load text file data to Oracle Database table?

Metalink note 33247.1 explains how to use text_io as suggested by Robin to read the file into a Multi-Row block. However, that article was written for forms 4.5 and uses CREATE_RECORD in a loop. There was another article, 91513.1 describing the more elegant method of 'querying' the file into the block by transactional triggers. Unfortunately this more recent article has disappeared without trace and Oracle deny its existence. I know it existed as I have a printed copy in front of me, and very useful it is too.

How to use UDL file in Powershell script?

Hello Scripting Guys,
I have a VBScript that works great for connecting to an Oracle DB using a .UDL file. Here is the important part of the script:
Set dataconnect = CreateObject("ADODB.Connection")
Path= "File name=C:\UDLs\TEST.udl"
dataconnect.ConnectionString = Path
dataconnect.open
Set oCmd = CreateObject("ADODB.Command")
oCmd.ActiveConnection = dataconnect
oCmd.CommandText = "SYSTEM.JOB.INSERT_JOB"
oCmd.CommandType = 4
set oParam = oCmd.CreateParameter("job_name_val")
oParam.type = 200
oParam.direction = 1
oParam.size = 255
oParam.value = job_name
oCmd.Parameters.Append oParam
set oParam = oCmd.CreateParameter("description")
oParam.type = 200
oParam.direction = 1
oParam.size = 4000
oParam.value = descrip
oCmd.Parameters.Append oParam
set oParam = oCmd.CreateParameter("status_val")
oParam.type = 200
oParam.direction = 1
oParam.size = 50
oParam.value = status
oCmd.Parameters.Append oParam
oCmd.Execute
As you can see, it creates "ADODB.Connection" and "ADODB.Command" objects. Everything works as intended here.
Now, I'm trying to convert this VBScript to a Powershell script.
Here's what I have so far with my PowerShell Script (non-working, but no errors):
$job_name = $args[0]
$status = $args[1]
$descrip = $args[2]
write-host "Job Name = " $job_name
write-host "Status = " $status
write-host "Description = " $descrip
#Create an object of type: ADODB class: Connection
$objConn = New-Object -com "ADODB.Connection"
#Create Connection String
$connString = "File name=C:\UDLs\TEST.udl"
#Open the connection
$objConn.open($connString)
#Command Object
$oCmd = New-Object -com "ADODB.Command"
#Assign DB connection To Command
$oCmd.ActiveConnection = $objConn
#Set Command text
$oCmd.CommandText = "SYSTEM.JOB.INSERT_JOB"
#Set Command Type
$oCmd.CommandType = 4
#Create parameter list For Command
#Job name Parameter
$oParam1 = $oCmd.CreateParameter("job_name_val")
$oParam1.type = 200
$oParam1.direction = 1
$oParam1.size = 255
$oParam1.value = $job_name
#Append parameter list
$oCmd.Parameters.Append($oParam1)
#Description Parameter
$oParam2 = $oCmd.CreateParameter("description")
$oParam2.type = 200
$oParam2.direction = 1
$oParam2.size = 4000
$oParam2.value = $descrip
#Append parameter list
$oCmd.Parameters.Append($oParam2)
#Status Parameter
$oParam3 = $oCmd.CreateParameter("status_val")
$oParam3.type = 200
$oParam3.direction = 1
$oParam3.size = 50
$oParam3.value = $status
#Append parameter list
$oCmd.Parameters.Append($oParam3)
#Command Execution
$oCmdX = $oCmd.Execute
write-host $oCmdX
#Cleanup
#Set parameters = To NULL
$oParam1 = $null
$oParam2 = $null
$oParam3 = $null
#Set Command = To NULL
$oCmd = $null
#Close DB object
$objConn.Close()
So, not too many changes with the syntax, but it doesn't actually send the ADODB Command to the Database. I have also tried hardcoding the connection string, but no luck there either. Am I not using the right syntax with the Command object? I am fairly new
to both of these languages, so I appreciate any help/suggestions you can offer!
Thank you,
Brian

Thanks JRV.
I am now getting this error (at least some feedback from Powershell now):
Exception calling "Open" with "1" argument(s): "[Microsoft][ODBC Driver Manager
] Data source name not found and no default driver specified"
At C:\temp\JobMon.ps1:21 char:14
+ $objConn.open <<<< ($connString)
+ CategoryInfo : NotSpecified: (:) [], MethodInvocationException
+ FullyQualifiedErrorId : ComMethodTargetInvocation
The thing is, it shouldn't be using a Microsoft driver. It should be using the Oracle Client driver (which I have installed and tested successfully using TNSPing).
Do I need to declare some sort of "using System.Data.OracleClient namespace" like in C++? How would I do that in Powershell?
Thanks again,
Brian

Read/Write text files in LabVIEW

We have developed an instrument control and data acquisition system for a mass spectrometer using LabVIEW FPGA. Currently we have 6 counters on the FPGA, counting for 1 second intervals and transferring data to the host using a FIFO.
The data, as a local variable, is used in several different parallel loops on the host. One of these is coded to write the data to a text file. Unfortunately everything we have tried has failed. It is proving impossible using either the write to file VI provided with labVIEW, or to use the Open file, write and close file utilities. Each attempt has failed. Yet when running a dummy code we can write to files. The dummy code consists of 6 random number generators running in one loop and the write to file VI in a second loop. The random numbers are transferred across the loops as local variables.
Can anyone offer any advice as to what we might be doing wrong. We're beginning to feel as though we are banging our heads against a brick wall and getting very frustrated.
Many thanks in advance for any suggestions.

Hi Paul,
you neither say, what is failing nor do you show any code... How should we help then?
"impossible using ... the write to file VI"
Well, usually they work just fine.
"Each attempt has failed."
In which way? Error number given? Did you use the debuging tools, like probing, breakpoints and highlighting?
"as local variables."
It seems you're not properly do program "real" LabVIEW code
