Labview using access database

"I need to use labview in order to read and write to an access database (8 columns per entry). I'm not too familiar with the program, but i know that we have the database connectivity toolset and the sql toolset installed. Does anyone have any simple examples laying around for someone who isn't labview savvy?"

I did a search of the examples on the web site and found 100s of examples on LabVIEW and an access database. Do a search at this link for "microsoft access database labview" Example Code Library
The top example I found is titled "Write Table in Columns to an Access Database" which sounds pretty close to what you are looking for.
Hope these help.

How to use access database

is it possible to use access database in visual basic 2012

Hello,
There are two main methods for working with MS-Access databases in Visual Studio with VB.NET. One method you go through several steps which the IDE data wizard creates strong typed classes and assist with binding fields in the database table to controls
such as a DataGridView, ListBox, TextBoxes etc. The second method you actually write all the code which can go in two different directions.
Which one to pick is dependent on your expertise in general with VB.NET. Both have advantages and disadvantages.
The following shows the beginnings of working with data wizards in the IDE while
this page is an index for the link just provided with a mixture of examples.
If open to suggestion and dependent on your needs please consider looking at using SQL-Server since there is an Express version of SQL-Server installed with Visual Studio. SQL-Server is overall and better choice but does not mean it's best for you at this
time but worth considering.

Mac's ability to use Access database

I am considering buying an apple mac after many years using a PC. I currently use Access database and will need to continue to review access databases and support colleagues in offices where PC is the norm. Am I on a Mac able to view and use Microsoft Access. On the Mac site I can only find reference to Word, Exell and Powerpoint being compatible. Thanks for any help offered.

Welcome to Apple Discussions
Microsoft does not make a Mac version of Access. You could use Boot Camp to create a Windows partition & install Windows & a PC version of Office. This would require restarting in Windows whenever you want to use Windows. Or use Parallels or VMWare Fusion to create a virtual PC & again install Windows & PC Office. I prefer using Crossover Mac which does not involve installing Windows. I have Office 2007 installed in Crossover to run Publisher when someone sends me a Publisher file. Unlike Boot Camp, Parallels or VMWare Fusion, Crossover doesn't support all Windows programs, but it definitely supports Office.

What is the best way to use TestStand/Labview to access database?

Is it best to use the TestStand database step types or use existing Labview database connectivity code to access database?
The database will contain configuration data and results data. I am also not using the standard results collection feature. (Test procedure will possibly last days so I think it is inappropriate to use results collection feature.)
I'm just trying to make my code "future proof".
Thanks

tbob wrote:
I have used both and I find that it is easier to use the Labview Database Connectivity Toolset. One step in a TestStand sequence can call the Labview vi. If done in TestStand, it takes many steps which I find harder to read and understand compared to Labview code. If it is just a simple one time access, TestStand may be a little easier, depends on one's preference.
Thanks.
I was thinking it would be easier to use the Labview code. I was just trying to sense if the community thought it was old hat and I should be using the TestStand code.

USING ACCESS DATABASE AS BACKEND

I need to use the form applications need to use MS ACCESS database as backend rather than ORACLE. How to reach it. Kindly help me to reslove it.
Can you please tell me the steps involved in this process.

I'm going to guess that you have a good reason for wanting to use MS-Access as the back-end database, but why use Forms as the front-end? Why not just use Access's UI?
Now to your question. You can connect to MS-Access using ODBC. Here is a [link to a good discussion|http://forums.oracle.com/forums/click.jspa?searchID=-1&messageID=3763074] on using ODBC. Hope this helps.

Using access database

I would like to use the data I have in an access database.
I can't get it right, the only idea is that I have a page
where there are 15 thumbnails, with text from the database.
Clicking the thumb would open a page with more information
and photo's from that object.
How can I do this?

How to reference MS Access database in ColdFusion MX 7 on 64-bit Windows

I am migrating customers from:
Windows 2000 Server (fully patched)
Internet Information Services (IIS) 5
ColdFusion 5
to:
Windows Server 2003 Standard x64 Edition (fully patched)
Internet Information Services (IIS) 6 (running in 32-bit
mode)
ColdFusion MX 7 (7.0.2) Standard
Unfortunately, some of these existing customers are still
using Microsoft Access databases instead of SQL Server. Having all
of these existing customers migrate to SQL Server is not yet
practical. On the old Windows 2000 / ColdFusion 5 server, they are
using OLE DB data sources to reference the MS Access databases
using the "Microsoft.Jet.OLEDB.4.0" provider. None are configured
to use ODBC drivers when referencing MS Access or SQL Server.
I have yet to figure out how to get ColdFusion MX 7 to:
- Create a data source that references MS Access databases on
64-bit Windows.
- Reference an existing MS Access data source created with
the 32-bit version of the ODBC Data Source Manager on 64-bit
Windows.
A bit of background information regarding MS Access on 64-bit
Windows:
- At the time of this writing, Microsoft has not
created/released 64-bit drivers for Microsoft Access and it's
unlikely they ever will, for understandable reasons.
- Contrary to seemingly popular belief, the Microsoft Jet 4.0
Database Engine does exist on 64-bit Windows. See the following
regarding version and file location information:
How to obtain the latest service pack for the Microsoft Jet
4.0 Database Engine
http://support.microsoft.com/kb/239114
- You CAN create MS Access based data sources within 64-bit
Windows, but they have to be made using the 32-bit version of "ODBC
Data Source Manager". I'm assuming these DSNs may only be used by
32-bit applications, but I have not tested that theory.
32-bit data sources:
ODBC Data Source Manager:
%SystemRoot%\SysWOW64\odbcad32.exe
Registry location:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ODBC
Default file DSN directory:
C:\Program Files (x86)\Common Files\ODBC\Data Sources
64-bit data sources:
ODBC Data Source Manager:
%SystemRoot%\system32\odbcad32.exe
Registry location:
HKEY_LOCAL_MACHINE\SOFTWARE\ODBC
Default file DSN directory:
C:\Program Files\Common Files\ODBC\Data Sources
The 64-bit version of "ODBC Data Source Manager" (under
Administrative Tools) only show "SQL Server" and/or "SQL Native
Client" as options when creating new data sources, unless
third-party software is installed that supplies additional drivers.
The 32-bit version of "ODBC Data Source Manager" (by default,
there is no shortcut for this in the Start menu) shows the typical
drivers seen on 32-bit versions of Windows, including SQL Server,
SQL Native Client, Microsoft Access, Excel, FoxPro, Paradox, etc.
When using ColdFusion Administrator in ColdFusion MX 7.0.2 in
64-bit Windows 2003 (IIS is running in 32-bit mode to allow
ColdFusion MX 7 to function at all), two problems are encountered
when dealing with MS Access (and presumably other 32-bit drivers).
In both cases, ColdFusion is trying to reference the registry
location for 64-bit data sources instead of 32-bit:
1. Creating a new data source within ColdFusion
Administrator:
Data Source Name: whatever
Driver: Microsoft Access
CF Data Source Name: whatever
Database file: (physical path to whatever.mdb)
(other settings are irrelvant for this example)
Error generated when submitting:
Unable to update the NT registry.
Cannot open HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBC.INI\ODBC
Data Sources: Windows error number 5 occurred.Access is denied.
ColdFusion stores the data source, however a "verify"
generates the following error:
Connection verification failed for data source: whatever
java.sql.SQLException: [Macromedia][SequeLink JDBC
Driver][ODBC Socket]internal error: Data source name not found and
no default driver specified
The root cause was that: java.sql.SQLException:
[Macromedia][SequeLink JDBC Driver][ODBC Socket]internal error:
Data source name not found and no default driver specified
2. Creating the data source using the 32-bit version of "ODBC
Data Source Manager" then trying to reference it with ColdFusion:
ODBC Data Source Manager:
System DSN or File DSN:
Name: whatever
Driver: Microsoft Access Driver (.mdb)
Database: (physical path to whatever.mdb)
(creation is successful within ODBC Data Source Manager)
Reference the above DSN within ColdFusion Administrator:
Data Source Name: whatever
Driver: ODBC Socket
Error generated when submitting:
Error accessing available odbc datasources. - Cannot open
HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBC.INI\ODBC Data Sources:
Windows error 2 occurred.The system cannot find the file specified.
ColdFusion MX 7 can't find the 32-bit data source on 64-bit
Windows because it's looking for it in the wrong registry location.
Can ColdFusion MX 7 be configured to look in
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ODBC
instead of
HKEY_LOCAL_MACHINE\SOFTWARE\ODBC
on a 64-bit Windows machine?

Paul,
Thanks for the insight on this. Regarding the initial problem
I ran into with creating Access based DSNs, very early-on, I
noticed there were two different driver options for Access
displayed within ColdFusion MX 7 Administrator:
Microsoft Access
Microsoft Access with Unicode
For reasons I'm am still baffled over, I somehow completely
forgot about and through the wonders of apparent tunnel vision,
completely overlooked the "Microsoft Access with Unicode" driver
option when I was running through my tests.
At your seemingly-obvious suggestion, I created a data source
using the Microsoft Access with Unicode driver and it worked
perfectly fine with the one customer's web site I'm using for
testing (of course, this is a copy--the production site is still
housed on the old ColdFusion 5 server). This obviously doesn't
actually fix the underlying issue with ColdFusion looking in the
wrong part of the registry on 64-bit Windows, but at least when it
comes to dealing with Access databases, your suggestion of using
the Microsoft Access with Unicode driver appears to be a functional
work-around. So long as there aren't any surprises waiting for me,
hopefully this will also work for the remaining ColdFusion sites I
have to migrate that are using Access databases.
Since you mentioned JDBC drivers in comparison with ODBC, I'm
pointing out a couple of references in case they're helpful to
anyone following this thread:
ColdFusion MX 7 - About JDBC
http://livedocs.adobe.com/coldfusion/7/htmldocs/00001736.htm
Types of JDBC technology drivers
http://java.sun.com/products/jdbc/driverdesc.html
http://java.sun.com/products/jdbc/
I don't actually develop anything in ColdFusion, so I'm
dealing with all of this from a server administration standpoint
since we do have some domain hosting customers that do develop or
at least have existing ColdFusion based sites. I am all
too-familiar with the caveats of using Access in any kind of
production or heavily used environment and have spent years keeping
users away from ODBC. For ColdFusion users, that meant creating OLE
DB DSNs and often having to fix poorly written SQL statements and
fixing ColdFusion date-related values and boolean values (the
common problems encountered when switching CF / MS Access users
from ODBC to OLE DB). I can only recall running into problems with
a single SQL Server based ColdFusion site when migrating from ODBC
to OLE DB. That customer never did get their many coding problems
fixed, so they're the only ones still using ODBC in CF. I have no
idea what'll happen when that one site gets migrated over--if it'll
even work. Obviously a lot of things have changed between
ColdFusion 5 and the MX versions that have come along afterward.
Thanks again for the Access with Unicode driver tip and JDBC
info. It looks like I can finally start moving forward again with
the site migration process.

We are looking to deploy Forte to Win 3.11 and Win95 users. We are
using Access database tables to hold data cache locally, rather than
pull it across the wire.
We have ODBC drivers for Win95 but are going to get 16bit 3.11 drivers
from VB v4.
Has anyone else tried this and if so, are there any pitfalls or helpfull

Hi Askok. This exception usually means that the weblogic server's environment
doesn't have all it needs to make the jdbc connection you want. You should
ensure that the OS environment variable PATH has all the libraries you need
for making a jdbc-odbc connection, and that it's classpath also contains the
driver you want.
What DBMS are you connecting to? The reason I ask is because if there is a
pure JDBC driver for it, that will be preferable, because the jdbc-odbc bridge
from Sun is not threadsafe, so it can corrupt Weblogic.

Connection to ODBC access database failure

I have made several sites using ACCESS databases via ODBC DSN
name. But suddenly it does not work any more. I can not use the
Database wizards in DM 8.02. When I have made a connection, tested
it OK and I try to se the tables/views. I only got the word "none".
If I in the advanced recordset wizard write the SQL command, the
data is showen correctly!!???
There is something wrong with DM's abillitry to connect to
the ODBC DNS name...Everything is updateted to the latest version.
Is there anybody who have any clue to what could be wrong. It
is the same story on an old 2000 Server, a new 2003 small busines
server and from DM installed on two different clientmaschines and
on the two servers.

Hi!
You could try this It worked for me on all my connections.
I found a extension called SP2DBFix1.0.2.mxp
Down load here,
http://download.macromedia.com/pub/dreamweaver/extensions/SP2DBFix1.0.2.mxp
to fix a XP pro service pack2 connections.
To fix: I went to Sites/Advanced/Remove connection Scripts,
ran that removed
my
connection scripts. I then shut down Dreamweaver 8 installed
the extension
then opened dreamweaver 8 made a new connection and it works
now Great! Im
happy.
You have to run this same routine on every site you have
setup with
connection scripts
Good Luck.

How to create a table in MS Access from Labview using ActiveX?

I want to transfer datas from Labview to Access using activeX method. My only problem is to find out how to create a new table (array) in Access from the Labview program.
Remarks: I use Labview 6i and MS Access 2000.
For the moment I can write and read datas of Access from Labview.
If someone could help me... that would be grate!

This is off the Microsoft MSDN site "creating an external table". I think you can drop the last step.:
Open the database you want to create the table in. If it is the current database, use the CurrentDb function to return an object variable that represents the current database. If it isn�t the current database, use the OpenDatabase method to open the database you want.
Use the CurrentDb function to create a Database object that points to the current database.
Use the CreateTableDef method of the Database object to create a table definition for the Microsoft Access table.
Use the CreateField method of the TableDef object to create one or more fields in the Microsoft Access table.
Use the Append method of the Fields collection to add the new field or fields t
o the Microsoft Access table.
Use the Append method of the TableDefs collection to create the Microsoft Access table.
Use the TransferDatabase method to create the external table in the specified folder.
Use the Delete method of the TableDefs collection to delete the Microsoft Access table definition.

Transferring a lot of data from Access Database to Labview

I need to transfer 500000 -> 1000000 values in a Access database table to Labview. The values are selected using a query which is very fast if run in Access itself, but from Labview it's very slow. Obviously the connection between Labview and Access is the slow point.
Im using the NI Database connectivity toolset and a UDL file defines the connection. Microsoft Jet 4.0 OLE DB Provider is used.
To be honest i dont know what that really means, just that it normally works but now its stupidly slow for so much data.
Thanks for any help.
Rob

One of my continual gripes with the DBCT is it's poor behavior on large data sets. See NI's response here:
http://digital.ni.com/public.nsf/3efedde4322fef19862567740067f3cc/862567530005f0a186256a33006b917a?OpenDocument
Actually, I wouldn't find it nearly so annoying but for the part that says "In most database books you are told not to return large recordsets...". I prefer the freedom to make a mess of things myself, thanks.
On the plus side, the VI referenced in the article is fairly efficient, you just have to deal with type conversion once things have been moved into LabVIEW.
