Hi Thomas,
You need to create an image field and in the source choose 'graphic content ; give the name of the variable which has the binary data . and give the type as 'MIME/image'.

How to add the fields into combo ?

Hi,
I want to add the table fields into combo box. Now I am able to getting the columns from table but I don�t know how to add that columns in combo box.
My jsp getting the columns from table.

     try {
     Connection con = null;
     Class.forName("oracle.jdbc.driver.OracleDriver") ;
     con = DriverManager.getConnection("jdbc:oracle:thin:@10.60.4.25:1521:clopaydb","scott","tiger");
     String query = "SELECT * FROM emp";
         DatabaseMetaData dma = con.getMetaData ();
         Statement stmt = con.createStatement ();
          ResultSet rs = stmt.executeQuery (query);
          ResultSetMetaData rsmd = rs.getMetaData ();
          int i;
          int numCols = rsmd.getColumnCount ();
          for (i=1; i<=numCols; i++) {
          if (i > 1) System.out.print(",");
          System.out.print("\nThe Table Column list "+rsmd.getColumnLabel(i));

          catch (Exception ex) {
          ex.printStackTrace ();
     }Please give me a sample code for add these items into combo. (I need JSP sample code )
Thanks & Regards,
Merlin Roshina

function metadata(){
try {??
Are you sure on this ? Dont mix javascript function with a java method.
Make a java bean and your method may return an ArrayList.
In your JSP ..
<select name="yourComboBox">
<%
// Make a For Loop for the arraylist
String columnLabel = (String ) arrayList.get(i);
<option value="<%=columnLabel%>"><%=columnLabel%></option>
<%
} // end bracing of for loop
%>
</select>
Post your code based on the directions above then we can help you more on this if reqd.
Probably you should look up into sample JSP ..JDBC sample codes on google.

How to add an image file to Oracle db?

Wanneer een request.getInputStream wordt geconferteerd naar een "String" (zie later) dan ziet de output in tekstformaat er als volgt uit:
-----------------------------7d280152604f4 Content-Disposition: form-data; name="oploadfile"; filename="C:\WINNT\Profiles\mvo\Desktop\boodschap.txt" Content-Type: text/plain Deze boodschap dient te worden ge-insert in de database. -----------------------------7d280152604f4 Content-Disposition: form-data; name="StadID" 1234 -----------------------------7d280152604f4 Content-Disposition: form-data; name="SuccessPage" /forum/error.jsp -----------------------------7d280152604f4--

How to add an image in multiple pages?

Hi,
First be aware that before posting this, I digged into Google but could not find a solution.
How to add an image in the footer section of a PDF document of size, say, 500pages? I am not going to add it one by one in very page, it's too time consuming.
Is there a way to add it in the footer section or any other alternative, so that I end up with the same image in an exact position in all 500 pages?
Thanks for your reply
Best,

How to add an image to a JPanel ?

hi,
do you now how to add an image to a JPanel ?
thanks a lot !

You can either use the Graphics method drawImage from the panel's paintComponent(Graphics g) method, or you can create an ImageIcon, with your Image in its constructor. And then create a JLabel, passing that ImageIcon in its constructor. Then, you can simple use the panel.add() method to add that JLabel.
For using the paintComponent method, check out the thread already posted above (I'll type it in again just in case)
http://forum.java.sun.com/thread.jsp?forum=31&thread=288769
If you want to use a JLabel, you can do something like this:
Image img;
JLabel label = new JLabel(new ImageIcon(img));
JPanel panel = new JPanel();
panel.setLayout(new FlowLayout());
panel.add(label);Val

How to get value of html combo box (i.e select) in jsp?

Hello,
I was just wondering how to get value of html combo box in jsp page. My code for combo box is:
<select name="combo" size="1">
<%
List<Project> projects = mgr.getProjects();
for(Project project : projects){
%>
<option value="<%= project.getId()%>"><%= project.getName()%></option>
<%
%>
</select>
I thought combo.value might give me the value, but it throws exception.
Any help is appreciated.
Thanks.

The combo does not exists in Java, but only in HTML. You have to submit the form containing the combo and then use request.getParameter("combo") to get it's value ;-)

How to add external images onto a control and still be able to resize

Hello,
I'm a LabVIEW newbie. I'm trying to customize the appearance of my VIs, and one of the things I like to do is to import external image and paste it onto the faceplate of the gauge indicator. I've followed the instruction in the Labview application note using the control editor and was able to paste the picture into indicator. But when I use it in the front panel and resize the gauge indicator, the image (added as a decoration) doesn't resize together with the indicator. My questions are:
1. How to add external images onto a control/indicator and still be able to resize the image automatically when I resize the control/indicator?
2. How to "add" a new part to an existing control/indicator? It looks like I can only customize/modify the existing parts of the control/indicator in the control editor.
Any help is appreciated. Thanks.

1/ Do not use the image as an added decoration. Instead replace part of the control with the image. Tis is illustrated in the attached vi : the arrow was pasted as a decoration, and also used to replace the slide cursor. Changing the control size do not affect the decoration, but changes the cursor.
2/ What do you mean by adding new parts to a control. We have just seen that it was possible to modify a control. Now, if you want to include additionnal functionnality, that's another story. You can replace parts of the control, and this can give interesting results. You can edit a slide control, and replace the numeric indicator by another control, including a numeric indicator, that you can replace with etc...
But there, it still the same info displayed under different forms. If you want to have several independant functions on the same control, such as a string display and a boolean and a numeric indicator, then that's a job for a cluster...
