How to view images which resides in the database using JFrame.

Hello defts,
Im developing an application using swings. I need to display a image in a JFrame during an button click event. where that image resides in the database.

the image shouldn't be in the db, just the path to the image location.
so, open the db, get the location, close the db, get the image from the location,
then either add the image to the frame via a JLabel or a JPanel (and its paintComponent()).
when you add/remove components to the frame you will need to call
frame.validate();, and possibly also
frame.repaint();

How To display a table that resides in the database via JFrame.

Hi,
I need to display the contents that present in the table that resides in my database.
Scenario:
Im having Main frame window, in that im having a button, while clicking that button a new JFrame should be opened & it should display all the rows & cols of dat table that resides in my DB.
I have no prob in opening a new JFrame during a button click, but i dont knw how to display table in the table format.
I tried JTable but i dont know how to pass the data into the JTable.
Kindly help me out!!!

JTable relies on a TableModel to deliver data. You have several ways of providing this data:
- Read it into either a Vector of Vectors (list of rows containing list of columns) or an Object[][] and create the JTable while passing the data.
- Create a javax.swing.table.DefaultTableModel, pass it to the JTable as a model, configure it and call addRow() in order to add rows.
- Create a custom table model class; see javax.swing.table.AbstractTableModel for a convenient base class

How To Insert List of Record To the Database Using Linq

Good day every one, Please i need little help, I have a list of record like this
lblID.Text = string.Join(" ", numbers);
gives the Numbers below...
6131
5241
3978
6824
3842//To Save to the database
int pin = int.parse(lblID.Text);
Now i want to insert those Numbers to the database
Persons ps = new Persons();
ps.Number = pin;
cdc.Persons.AddObject(ps);
cdc.SaveChanges();
it throws up error...
what i want to achieve on button insert
all Numbers will be inserted but before inserting the number it will check if those numbers exist first on the database
it should be like this on the database
ID Number
1 6131
2 5241
3 3978
4 6824
5 3842
thanks.. I do appreciate your time and effort

Hello,
>>Now i want to insert those Numbers to the database
For inserting a list of items to database, a loop statement is needed. I do not how you get these numbers, I assume they are stored in a collection and you could check below demo sample to insert these numbers and I assume your person table is identified:
using (DFDBEntities db = new DFDBEntities())
List<int> numbers = new List<int>() { 6131, 5241, 3978, 6824, 3842 };
for (int i = 0; i < numbers.Count; i++)
int number = numbers[i];
//Check if the local and database already contains this number
bool isRecordExist = db.Tables.Any(t => t.Number == number) || db.Tables.Local.Any(t => t.Number == number);
if (!isRecordExist)
Table t = new Table();
t.Number = number;
db.Tables.Add(t);
db.SaveChanges();

I am using a servlet that retrieves the BLOB from the database, sets the MIME type and puts it in a stream. The code is :
package TestQueryITM;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.*;
import java.net.*;
import java.sql.*;
import oracle.sql.*;
import oracle.jdbc.driver.OracleDriver;

public class MIMEServlet extends HttpServlet {
DbConnect myDbBean = new DbConnect();
int Id=6;
String MIME ="plain/text";
public void init(ServletConfig config) throws ServletException
super.init(config);
public void doGet(HttpServletRequest req,HttpServletResponse res)
throws ServletException, IOException
try
String content_type = new String();
String filename = new String();
// Load the Oracle JDBC driver:
Class.forName("oracle.jdbc.driver.OracleDriver");
// Connect to the database:
Connection conn = DriverManager.getConnection
("jdbc:oracle:thin:@ORAVISION:1521:DEV","[username]", "[password]");
// It's faster when auto commit is off:
conn.setAutoCommit (false);
// Create a Statement:
Statement stmt = conn.createStatement ();
try
BLOB lob_loc = null;
java.io.InputStream in = null;
int pos = 0;
int length = 0;
OracleResultSet rset = (OracleResultSet) stmt.executeQuery (
"SELECT text FROM test WHERE ID = "+Id);
if (rset.next())
lob_loc = ((OracleResultSet)rset).getBLOB(1);
MIME=rset.getString(2);
// File binaryFile = new File("C:/aantekeningen.doc");
// FileInputStream in = new FileInputStream(binaryFile);
in = lob_loc.getBinaryStream();
// This loop fills the buf iteratively, retrieving data // from the InputStream:
res.setContentType (application/pdf);
res.setHeader ("Content-Disposition","attachement;filename=test.doc");
ServletOutputStream op = res.getOutputStream ();
byte[] buffer = new byte[32000];
while ((in != null) && ((length = in.read(buffer)) != -1))
// the data has already been read into buf
System.out.println("Bytes read in: " +
Integer.toString(length));
op.write(buffer,0,length);
op.flush();
op.close ();
in.close();
stmt.close();
conn.commit();
conn.close();
}catch (SQLException e)
e.printStackTrace();
}catch(Exception e)
System.out.println(" ");
e.printStackTrace();
System.out.println(" ");
public String getServletInfo() {
return "TestQueryITM.MIMEServlet Information";

How to remove only one row from the database using labview6.1

using labview 6.1 I create a table with various rows and columns and store bulk of data's in them.,, what procedure should I follow to remove only one paticular row from the database? Help me out with an example please,,
Thanking you in advance!

Hi,
If you have the database toolkit you can delete a row using just a SQL Query to "DB Tools Execute Query.VI"
Example:
DELETE FROM Table name Where SerialNum='Value' And Date='Value' And Time='Value'
See also attached VI

How will I know which Scenario is my message using?

I have a problem figuring which scenario is my message using. We have this interface which has 2 similar scenarios. The scenarios are actually the same-everything inside it-the only difference is the scenario name. How would I know which scenario is the message using? I tried looking into the trace but I cannot find it there.

Mary,
As replied in the above posts, U can not create two sender comm channel or receiver determination for same interface from same source. As told, ur objects might have been copied to two scenrios which you have also confirmed.
Scenario name can be treated just as a container to hold the objects logically which belong to one process. It doesnt have any role in the execution of ur process.
You can try to change ur objects in any one scenario & same will be replicatd in other scenario also. So if I m nt wrong, I will conclude that scenario name is jst to combine the objects & doest have ny role in execution of process in XI.

I am using referenced images, saved on an external hard drive. It would be most helpful to transfer the new captions (version name) to the referenced images which still have the camera code on them. How can this be done? Thanks so much!

I am using referenced images, saved on an external hard drive. It would be most helpful to transfer the new captions (version name) to the referenced images which still have the camera code on them. How can this be done? Thanks so much!

You're question is hard to follow. Are you looking to rename your master files to the version name? Or are you looking to do something with IPTC caption field and the masters?

Adobe Cloud has 2 different Muse programs.... how do I know which one is the newer better version?

So I am new to Muse, and my Adobe Cloud has 2 different programs from Muse... how do I know which one is the newer better version?
One Must program (Muse CC 2014.2) has a black background when working on it... it looks like other Adobe programs such as Photoshop.
The other one is light color (Muse CC) very similar to the black color Muse on functions.....
One of the difference I notice is that the light color Muse has a few widgets in the library, while the black background Muse seems to have an empty library
So... why are there 2 different Muse programs in my Adobe Cloud?

Hi
The latest version of Muse is 2014.2, so you need to uninstall another version of Muse manually.
regarding the items in Library, you can add items in your library manually, as shown in this article
Adobe Muse Help | Organizing and reusing design elements using Library panel
Please let me know if you have any other query.

How to find out which type of the driver is used in our application?

Hi all,
can anyone tell me how to find out which type of the driver is used in our application?
Thanks in advance,
Phoeniox

Hi,
Check out this...
Class.forName("com.mysql.jdbc.Driver"); //if u r using MySql
List drivers = Collections.list(DriverManager.getDrivers());
 for(int i=0;i<drivers.size();i++)
 Driver driver = (Driver)drivers.get(i);
 String driverName = driver.getClass().getName();
 System.out.println("Driver "+i+":::"+driverName);
you need to load the driver and display in the same program.
Then only you'l get the required result.

How to edit bitmap which is imported in flash using xml and save the edited bitmap back to xml in flash.

hi all
It would be appreciated if any one let me know how to edit
bitmap which is imported in flash using xml and save the edited
bitmap back to xml in flash.
Is it posible to save the bitmap data in flash?
thanks in advance

Yes you can... but like I said before you need to upload the
data from the changes you make to a server.
In terms of the solution... its unlikely that you'll find one
specifically for your needs. You will have to learn whatever you
don't know how already and maybe adapt some existing examples to
your needs.
To change the visual state of a movie clip... you just do all
the regular things that you want to do to it using flash... scale,
rotation, drawing API , textfields etc in actionscript. If you
don't know how to how to do that stuff, then you need to learn that
first. That's basic actionscript.
You can capture the visual state of a movieclip using the
BitmapData class. That includes a loaded jpeg. You can also
manipulate bimatp data using the same class. You should read up on
that if you don't know how to use it or check out the examples
below for uploading info.
For uploading to the server:
Here's an as2 solution that took 15 secs to find using
google:
http://www.quasimondo.com/archives/000645.php
If you're using as3, google search for "jpeg encoder as3" and
look through that info. There are also historical answers in the
forums here related to this type of thing that might help as
well.
