How to Read barcode using Gige camera qith vison software

Hi ,
I have a Gige vision camera, I need to use this to read the barcode and save it in a file. Is there a way to read a barcode directly from the camera using labview vison software.Please do let me know if there is a way.
Thanks,
Ankit G

Hi Ankit
I dont know if you have NI's Vision Builder for Automated Inspection, it has a function to do Barcode reading, it is very convenient tool to use with lot of good examples.
Kudos are welcomed
Thanks & Regards,
Kunal Raithatha.

How to read 'Barcode' in Adobe PDF Forms?

Hi Everybody,
I have a scanned pdf of 20 pages. There is a barcode in every page in a serial order like in first page it is 545001 in second page it is 545002 and in third page it is 545003 and so on. I want to automate a process sothat i can know that all the barcodes are in serial order or not. Or, I could know whether it is tempered or not.
Please tell me. How i can do this using Adobe Acrobat or Adobe LiveCycle?
Is there any features in acrobat or livecycle?
Thanks,
Manjeet

It is an offline form.
We are consuming the web service in Form to create a PR.
However we also need the user to attach some documents before it actually clicks on the "Create PR" button.
User can attach the file through "Attachments" facility provided on Adobe Reader.
Our problem is how to check whether user has attached the documents or not. If the documents are attcahed then how to read them using JavaScript?

How to read OVD using java

Hi all,
how to access OVD using Java?
Thanks,
Kumar.P

Hi,
You can just normal LDAP API codes to connect to OVD the same way you connect to other LDAP servers.
PFB sample code for connecting to OVD.
Properties props = new Properties();
try {
props.load(new FileInputStream("LdapCredentials.Properties"));
} catch (IOException e) {
// TODO
ldapurl = "ldap://hostname:390";
ldapUser = "cn=orcladmin,ou=Org12,dc=ovid,dc=com";
userPassword = "welcome1"; //"Killtheking123456";
userContext = "ou=Join1,dc=ovid,dc=com";
Now, you have to get Directory Context as shown below.
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,
"com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, ldapurl);
env.put(Context.SECURITY_AUTHENTICATION, "simple");
env.put(Context.SECURITY_PRINCIPAL, username);
env.put(Context.SECURITY_CREDENTIALS, password);
//Initialize the Directory context
DirContext dCtx = new InitialDirContext(env);
Then you can perform search operations or new user creation etc., as you wish.
Does this help?

How to read barcode?

Hi,
In my application, we have a requirement of reading barcodes and generating barcodes for shipping lables. Do you have any idea about how to do this in a web application?
Thanks in advance
Regards,
Challa.

Hi rayudu,
We have a custom transaction in SAP to read a barcode tag, but we don´t have any configuration or code to get it. The software of reader makes all work.
You only have to configurate the reading device to simulate the entry of data in SAP, and then execute the wished process.

Alejandro.

How to read data using SQLGetData from a block, forward-only cursor (ODBC)

Hi there. I am trying to read data a small number of rows of data from either a Microsoft Access or Microsoft SQL Server (whichever is being used) as quickly as possible. I have connected to the database using the ODBC API's and have run a select
statement using a forward-only, read-only cursor. I can use either SQLFetch or SQLExtendedFetch (with a rowset size of 1) to retrieve each successive row and then use SQLGetData to retrieve the data from each column into my local variables. This
all works fine.
My goal is to see if I can improve performance incrementally by using SQLExtendedFetch with a rowset size greater than 1 (block cursor). However, I cannot figure out how to move to the first of the rowset returned so that I can call SQLGetData to retrieve
each column. If I were using a cursor type that was not forward-only, I would use SQLSetPos to do this. However, using those other cursor types are slower and the whole point of the exercise is to see how fast I can read this data. I can
successfully read the data using a block forward only cursor if I bind each column to an array in advance of the call to SQLExtendedFetch. However, that has several drawbacks and is documented to be slower for small numbers of rows. I really
want to see what kind of speed I can achieve using a block, forward-only, read-only cursor using SQLGetData to get each column.
Here is the test stub that I created:
' Create a SELECT statement to retrieve the entire collection.
selectString = "SELECT [Year] FROM REAssessmentRolls"
' Create a result set using the existing read/write connection. The read/write connection is used rather than
' the read-only connection because it will reflect the most recent changes made to the database by this running
' instance of the application without having to call RefreshReadCache.
If (clsODBCDatabase.HandleDbcError(SQLAllocStmt(gDatabase.ReadWriteDbc, selectStmt), gDatabase.ReadWriteDbc, errorBoxTitle) <> enumODBCSQLAPIResult.SQL_SUCCESS) Then
GoTo LoadExit
End If
Call clsODBCDatabase.HandleStmtError(SQLSetStmtOption(selectStmt, SQL_CONCURRENCY, SQL_CONCUR_READ_ONLY), selectStmt, errorBoxTitle)
Call clsODBCDatabase.HandleStmtError(SQLSetStmtOption(selectStmt, SQL_CURSOR_TYPE, SQL_CURSOR_FORWARD_ONLY), selectStmt, errorBoxTitle)
Call clsODBCDatabase.HandleStmtError(SQLSetStmtOption(selectStmt, SQL_ROWSET_SIZE, MAX_ROWSET_SIZE), selectStmt, errorBoxTitle)
If (clsODBCDatabase.HandleStmtError(SQLExecDirect(selectStmt, selectString, Len(selectString)), selectStmt, errorBoxTitle) <> enumODBCSQLAPIResult.SQL_SUCCESS) Then
GoTo LoadExit
End If
' Cursor through result set. Each time we fetch data we get a SET of rows.
sqlResult = clsODBCDatabase.HandleStmtError(SQLExtendedFetch(selectStmt, SQL_FETCH_NEXT, 0, rowsFetched, rowStatus(0)), selectStmt, errorBoxTitle)
Do While (sqlResult = enumODBCSQLAPIResult.SQL_SUCCESS)
' Read all rows in the row set
For row = 1 To rowsFetched
If rowStatus(row - 1) = SQL_ROW_SUCCESS Then
sqlResult = clsODBCDatabase.HandleStmtError(SQLSetPos(selectStmt, row, SQL_POSITION, SQL_LOCK_NO_CHANGE), selectStmt, errorBoxTitle)
Call clsODBCDatabase.SQLGetShortField(selectStmt, 1, assessmentRollYear(row - 1))
Console.WriteLine(assessmentRollYear(row - 1).ToString)
End If
Next
' If the rowset we just retrieved contains the maximum number of rows allowed, there could be more data.
If rowsFetched = MAX_ROWSET_SIZE Then ' there could be more data
sqlResult = clsODBCDatabase.HandleStmtError(SQLExtendedFetch(selectStmt, SQL_FETCH_NEXT, 0, rowsFetched, rowStatus(0)), selectStmt, errorBoxTitle)
Else
Exit Do ' no more rowsets
End If
Loop ' Do While (sqlResult = enumODBCSQLAPIResult.SQL_SUCCESS)
The test fails on the call to SQLSetPos. The error message I get is "Invalid cursor position; no keyset defined". I have tried passing SET_POSITION and also SET_REFRESH. Same error. There has to be a way to do this!
Thank you for your help!
Thank You! - Andy

How to read and use an API ?

Hi all,
In the Java Tutorial - Nested Classes chapter, one of the questions at the end is like this:
Q2. Use the Java API documentation for the Box class (in the javax.swing package) to help you answer the following questions.
a. What +{color:#3366ff}static nested class{color}+ does Box define?
b. What +{color:#993366}inner class{color}+ does Box define?
c. What is the +{color:#ff6600}superclass{color}+ of Box’s inner class?
d. Which of Box’s {color:#003300}+nested classes+{color} can you use from any class?
e. How do you create +{color:#ff0000}an instance of Box’s Filler class?+
+{color}+
{color:#000000}I can figure out the answers from a - d. But I don't understand the answers for e.
{color}{color:#008000}
Answer 2e: {color}new Box.Filler(minDimension, prefDimension, maxDimension)
Where do we find the answers for (minDimension, prefDimension, maxDimension)? Is it written in the API? We can't actually see the programming codes in an API, right?
Thank you for your reply.
{color:#ffff00}
Cheers~

If you look at the JavaDoc for the [Box.Filler constructor|http://java.sun.com/javase/6/docs/api/javax/swing/Box.Filler.html#Box.Filler(java.awt.Dimension,%20java.awt.Dimension,%20java.awt.Dimension)], then you'll see that it takes 3 Dimension objects.
Thank you! I was looking at the constructor of the wrong class - 'Class Box' instead of 'Class Box.Filler', no wonder I couldn't find it. :p Thx. :-)

Dimension minDimension = ...

Box.Filler filler = new Box.Filler(minDimension, prefDimension, maxDimension);That's it. Nothing more involved or mysterious.Thanks a lot for the code, I can visualize it better now.
P/S: Well, it was pretty mysterious for a while. 'Twas the very first time I've ever seen an API. ;-)

How to achieve image using digital camera of USB-type interface through IMAQ PCI-1424 board.

1.Is it doable?
2.How to connect USB-type interface with IMAQ PCI-1424 board.
Thanks!

See the Developer's Zone (www.ni.com/zone) for specifics on USB (search for "USB").
"1.Is it doable?"
- In short "no".
- USB is similar to FireWire (IEEE 1394), and no framegrabber is required. We offer an IEEE 1394 IMAQ driver to interface FireWire cameras with LabVIEW & CVI.
"2.How to connect USB-type interface with IMAQ PCI-1424 board."
- You will need a USB driver for the camera. The 1424 is not required.

for example : In above XML the code line : <item> SAPGUI ( FB01_120_STEP_3 ).</item> it doesn't have any comment line means this code don't have any comment. So vbscript should find such line numbers and code text and show error message.
3) Each code had its own comment just above line of code.
4) In <PARAMETER> node we have to check <PNAME> is staring with letter "I" or not.. If its staring with letter "I" then its <PTYPE> and <PGROUP> staring letter should be "I". We have to check this condition
for every child node of <PARAMETER> node using vbscript.
Please help me and Thank You so much in advance.
My Vb Script is as follows :
filename = "D:\Automation\o.txt"
Set fso = CreateObject("Scripting.FileSystemObject")
Set f = fso.OpenTextFile(filename)
fl=0
Do Until f.AtEndOfStream
strLine = f.ReadLine
if (strLine ="MESSAGE ( MSG_1 ).") then
  Document.write("<br>Inside MESSAGE ")
   Do until f.AtEndOfStream
strLine = f.ReadLine
if((Left(strLine,1)="*"))
Then
if((Right(strLine,1)="."))
then
Document.write("<br>ERROR Found at Line No :" & f.line-1&" "& strLine)
end if
   fl=1
else
if((Right(strLine,1)=".")
and (fl=1))Then
fl=0
  else
Document.write("<br>ERROR Found at Line No :" & f.line-1&" "& strLine)
end if
end if
Loop
end if
And the following code for <PARAMETER> tag :
Const XMLDataFile = "D:\Automation\imp\p.xml"
Set xmlDoc = CreateObject("Microsoft.XMLDOM")
xmlDoc.Async = False
xmlDoc.Load(XMLDataFile)
xmlDoc.validateOnParse = True
If xmlDoc.Load(XMLDataFile) Then
   Document.write "SUCCESS loading XML File"
Else
Document.write "ERROR loading XML File"
  End If
counter=0
Set root = xmlDoc.documentElement
Set items = root.childNodes
for each item in items
myPNAME = xmlDoc.getElementsByTagName("PNAME").item(counter).text
myPTYP = xmlDoc.getElementsByTagName("PTYP").item(counter).text
myPGROUP = xmlDoc.getElementsByTagName("PGROUP").item(counter).text
If (Left(myPNAME, 1) = "I") Then
'Document.write("myPNAME Starts with I")
IsValid = True
'Innocent until proven guilty
If (Left(myPTYP, 1) <> "I") Then
IsValid = False
End If
If (Left(myPGROUP, 1) <> "I" )Then
IsValid = False
End If
If IsValid = False Then
Document.write(myPNAME & " is not valid.")
End If
IsValid = True
End If
If (Left(myPNAME, 1) = "V") Then
'Document.write("myPNAME Starts with I")
IsValid = True
'Innocent until proven guilty
If (Left(myPTYP, 1) <> "V") Then
IsValid = False
End If
If (Left(myPGROUP, 1) <> "V" )Then
IsValid = False
End If
If IsValid = False Then
Document.write(myPNAME & " is not valid.")
End If
IsValid = True
End If
If (Left(myPNAME, 1) = "E") Then
'Document.write("myPNAME Starts with I")
IsValid = True
'Innocent until proven guilty
If (Left(myPTYP, 1) <> "E") Then
IsValid = False
End If
If (Left(myPGROUP, 1) <> "E" )Then
IsValid = False
End If
If IsValid = False Then
Document.write(myPNAME & " is not valid.")
End If
IsValid = True
End If
counter=counter+1
next


Here is a better example of how to pull all of the text.
strXmlFile = "D:\Automation\imp\p.xml"
Set xmlDoc = CreateObject("Microsoft.XMLDOM")
xmlDoc.Async = False
If xmlDoc.Load(strXmlFile) Then
WScript.Echo "SUCCESS loading XML File"
Else
WScript.Echo "ERROR loading XML File"
End If
Set items = xmlDoc.SelectNodes("//SCRIPT/ETXML_LINE_TABTYPE/item")
For Each item In items
WScript.Echo item.Text
Next

How to Read DVD using ioctl call

I used the ioctl call DKIOCCDREAD to read the CD content. Is any ioctl call to read the DVD content?
If not, How can I read the DVD content in the MAC 10.5.8?
