Read from database (Access) and update fields using MS ADODB
Hello,
I am trying to get records from database using MS ADODB._connection & ADODB._Recordset objects (from LabVIEW 6)
I can:
1. open connection (with ADODB._connection)
2. write into tables (with ADODB._command)
I can not: gets records and update fields using ADODB._connection & ADODB._Recordset.
I do not know:
1. how to connect between the connection that was opened and the recordset object
2. where I can write the SQL text as input to the recordset
Attached is DataBase.llb with DB_read.vi that display my steps.
Thanks.

Try this one, after updating the names for database and the table you want.
Let me know if it's working.
p.s.: if you have problems, it could be a different adodb version ... but the sequence of methods is the same

Reading from XML file and updating the table ????
Hi
I have package which reads the hier.XML file and does Update inserts into the 5 tables
i have table called MAIN_tbl with the column cur_date.
The package kicks if this cur_date is one day less than the hier.XML file DT.
Currently i m manually checking this date's to make sure the Main_tbl cur_date is n sync with
hier.XML file DT.
for example :- hier.xml file DT is "20091020" then main_table cur_date should be 10/19/2009
in order to kicks of the pakage.
what i m looking to do ??
compare the hier.xml DT with the main_table cur_date,
if cur_date is -1(Preivous day) of hier.xml DT then run hier_pkg(Package)
if not then update main_table cur_date to -1(previous day) of the hier.xml DATE
Then later write the above logic to update the main_table in a procedure, and
then call the package from the procedure.
below are the top few lines of the hier.XML file which is relevant to the one which we are trying to do
<?xml version = '1.0'?>
<HIER_POSTING num ="111" HIER_TYP="CD" DT="20091020" Global="Y">
FYI : The hier.XML file is located in UNIX space.
How do i accomplish this. any idea ????
Thank you so much in advance. For giving a thought on this problem!!!Any thought on this guys ???

Add fields to maintenance view and update then using events
Hi experts:
I've created a table with 4 fields, one of them is userid. Also, there is a maintenance view to add new entries.
I want to display user name when typing userid using events (1 or 21). I know how to do it if username is one of the fields of the table, but there is a requirement to not store username in the table, just userid.
My question is: is possible to add a field into the maintenance view and update it using events but not store the value in DB?.
Thanks in advance for your help.
Regards,
Carlos.In the save event just clear the entries of the field(user name) in the internal table.

ImageIcons read from database don't appear
Hi,
I create a JavaBean to show images from filesystem and database (oracle9i) in a JTable.
The ImageIcons loaded from filesystem appear fine whith my defined DefaultTabelModel.
The ImageIcons read from database (jdbc2) with the same DefaultTabelModel appear in the correct count, but the fields or placeholders of the Images, saved as blob, are blank.
The partcode of my resultset is
BLOB myblob = null;
int bufsize = 0;
while(result.next())
myblob = ((OracleResultSet)result).getBLOB("image_container");
bufsize = myblob.getChunkSize();
byte[] buffer = new byte[bufsize];
ImageIcon icon = new ImageIcon(buffer);
Object [] row = {icon};
model1.addRow(row);
model1.fireTableDataChanged();
I don't get any errors.
Thanks
KlausHi,
I changed the datatype from BLOB to 'LONG RAW' for the image in the database.
while(result.next())
byte[] bytes = result.getBytes(1);
String jd = String.valueOf(bytes);
System.out.println(jd);
//get:[B@153 [B@154
//or [B@155 [B@156 for the 2.result
String name = result.getString(2);
System.out.println(name);
//get the correct result
FileOutputStream file = null;
file = new FileOutputStream ("c:\\"+name+".jpg");
file.write(bytes);
//it works fine !!!
ImageIcon icon = new ImageIcon(bytes); //it is correct ?
String ls = String.valueOf(icon.getImageLoadStatus());
String h = String.valueOf(icon.getIconHeight());
String w = String.valueOf(icon.getIconWidth());
System.out.println(h+" : "+w);
//get: -1 : -1
System.out.println(ls);
//get: 4
Object [] row = {icon,name};
//icon is blank, name appears correct in jtable
//but when I need:
//ImageIcon icon = new ImageIcon(AW_Frame.class.getResource("images/emac.jpg"));
//icon and name appears correct in jtable
model1.addRow(row);
model1.fireTableDataChanged();
any ideas ?

Hey,
I'want to make connection from my laptop(xxx.xxx.xxx.xxx = A) to a fixed computer(SQL server xxx.xxx.xxx.xxx =B). My connection string = "Provider=SQLNCLI11; Data source:name-pc/SQLEXPRESS; Integrated circuit=SSPI;Intial Catalog=Database name for visual
studio C#.
Laptop -> PC1 : Eror
It works when i use localhost or 127.0.0.1 and i can read my database without any problems if i install SQL server on my laptop. Know i install it to PC1 and uninstall on my laptop. When i change the name-pc by an ip-adress i get this error: Login failed.
The login is from untrusted domain and cannot be used with windows authentification. I did some research on multiple forums where they say about Local security policy(secpol.exe) but i don't have this file.
PC2-> PC3: work fine but i want to work with my laptop and i don't understand why it isn't working with my Laptop.
Can someone help me?
Thx a lot and sry about my english(its a disaster)
ThibautHello,
Yes, for the Windows Authentication to work you should be using the same Windows account and password.
Are you willing to create SQL logins inside SQL Server and allow your users to connect to SQL Server using SQL Authentication
instead of Windows Authentication? That could be a solution on a workgroup network.
Hope this helps.

Trouble reading from serial instrument and DAq simultaneously.
Greetings,
I am having some trouble getting my VI to read from my DAq and a serial instrument at the same time. If I run the subVI's simultaneously (i.e. subANG is running in one window and subVEL is running in a second window) both return the proper values and behave as I would expect. However, if I call the subVI's into a parent VI and try to run them both in the same loop structure subANG gets stuck and will not resond with a change in signal.
I have also tried to use a stacked or flat sequence to separate out the execution of subVEL and subANG, but I still get the no response from subANG.
The most confusing thing is that if I run Parent.VI in one window and then create a copy of subANG (call it '....-copy' or whatever) and run it in a second window, Parent.VI behaves properly and will refresh the readings as they appear in '...-copy'.
I have attached 3 files.
(1) subANG.VI -This reads an RS232 signal from an inclinometer. The signal is refreshed every 10ms or so.
(2) subVEL.VI -This reads raw voltage from one channel on the DAq, calculates the mean then converts that into a pressure differential and finally a velocity based on the pressure and temperature inputs.
(3) ParentVI.VI -This simply calls and displays the subVI's
My guess is that it is a buffer issue, but I am stumped. Does anybody out there in Labview land know why this might be happening? All suggestions welcom.
Solved!
Go to Solution.I am noticing it is not an NI DAQ card. How are you communicating with the DAQ? If it is using a serial port, that could be your problem.
I also highly recommend using the VISA drivers for serial communications instead of the serial.llb VIs.
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

Create Custom list form and validate fields using sharepoint designer 2010
Hi All,
I have a requirement to create a custom job application form which will be filled and submitted by anonymous users. I have a an option to create custom user control web part but I wanted to
create it using custom list form using SharePoint designer. My requirement is below
Date of birth (user age should be above 22yrs )
Email Validation
Phone validation
Resume attachment (should attach only word documents or PDF)
Qualification (If other is selected then show textbox else hide)
Can above validations be done using SharePoint designer (JavaScript or validation controls)? Or do I have to create custom control web part?
MercuryManHello,
I think jquery/javascript can be used to put validations on those fields. Fortunately some of validation can be done via sharepoint itself like: email, phone, age. For Attachment and Qualification fields use jquery/JS.
See below link for column validations:

http://sharepointsolutions.com/sharepoint-help/blog/2011/12/how-to-validate-an-email-address-using-column-validation-in-sharepoint-2010/

I purchased (and have now deleted) Aperture from my computer and want to use only iPhoto. (Aperture was simply too much program for me.) How do I delete Aperture albums but keep the pics in iPhoto? Please accept my apologies in advance if this is a dumber than dumb question. I simply want all vestiges of Aperture to go away with losing all my albums. Any help would be appreciated!
Aperture added a second view to your library.
You now have an additional section in your Source list , called events. But this section lists exactly the same events that you are seeing in the "Events" view. Don't delete anything from there, or you will delete your photos. But you can press the "Hide" button to collaps that section. But someday you may want to use this list. It makes it very easy to move photos between events. -
i am trying to sync iphone 5 to itunes but it says "iTunes could not connect to the iphone as an error occured while reading from the device " and the iphone is not seen on itunes........
First thing to try is to reset your device. Press and hold the Home and Sleep buttons simultaneously ignoring the red slider should one appear until the Apple logo appears. Let go of the buttons and let the device restart. And then reboot your computer.
See if that fixes your problem. -
How to Access and Update Existing DW site using DW 5.5 on new laptop?
We already use InDesign and have recently upgraded to 5.5. At the same time my partner bought a new laptop and decided to upgrade his version of DW. This was an early version, with no upgrade path, so he bit the bullet and bought DW 5.5 No problems installing it on his new laptop. His site is extensive but very basic - no addons. He has a good basic grasp of html.
What he would now like to do, is to download the remote site onto his laptop from its host and in future update it from his laptop.(He travels a lot.) As I said it is an early version of DW, predates CS versions but is just basic html. Is there a generally accepted way of doing this? If so is it in the tutorials etc? He can't find it in theHelp for 5.5?
Just to add, the new laptop would be the only location on which the website wouldbe stored. This is so he can update it from the road and keep to a single version to update.If you could bear with me a bit longer. My partner has an old version of DW and so some of the interfaces have changed.
Am I correct, he must open the local site on his old pc, using the orignal software on there, and then using Sites/Manage Site options export it in .ste format? (I am assuming his orignal DW version has these options.) Does he create the new export .ste version with the same name?
At this stage he should then have a .ste version of his site on his old computer. You say he should then" send" this file to the new laptop. Do you meant copy it onto a memory stick and import it to the new laptop as though it were a new file? Then go to the remote server to access the file there and update it?
One last question, my partner cannot find the command to access his remote site, in DW CS 5.5 - He says it is not where it is on his version. Where is the remote site access command in DW CS 5.5 please?
