Populating Image Item from 9i Database

Hi All,
I could store images into 9i database using Forms 6i Application. But I could not populate the stored images using Forms 6i application.
I appreciate very much for any help.
Thanks in Advance,
Umasankar.

Hi John,
Sorry for not explaining the problem completely.
Here is the details.
We are using Forms 6i and Oracle 8i. We are also planning to upgrade the database to 9i. I have application developed in Forms 6i. Using that application to connect 9i database, I could store images (from client system) into the 9i database (Using read_image_file). When I execute the query from Forms 6i application, I could not see the image from database. I was working OK with images on Oracle 8i database.
Thanks for your help.
Umasankar.

Problem Populating Image Item From Database

Hi All,
I am using Oracle 9i & Forms 6i on Windows platform & working in client/server model. I created a form in which, I am reading an image file from the file system & then saving it into the database. In the Databse, i created the column as BLOB. But, when I query, this does not retrive the saved image in Image Item. But image is actually saved. When I tried, changing the database column to LONG RAW, it is working. I mean its reading the image in the image item from the database.
Can anyone pls tell me, is there any problem like this, as we can retrive from LONG RAW but not from BLOB, or I am missin something here.
Regards

Hi,
I use Forms 6i to save and retrieve image in BLOB column without problems.
Some weeks ago, my column was long raw and I update it without problems. Nothing to do in Forms and juste modifiy query and recompile in Reports.

Populating menu items from the database...is it possible?

hi
using :forms 10g
we have a requirement in forms where we need to populate the menu items from the database.first we used hiearchial tree where it was possible.but since the requirement changed i am not sure that whether the menu items can be populated by data from the database...will be glad if someone could throw some light on this issue...
thanks

You could always do it but would need to put a fix limit on the number of menu items.
For example you could create a set of menu items at design time with the visible property set to False.
While reading the database, you then set them to True while setting the label to whatever you require.
But it all depends also on what you want your menu items to do when selected.

is it possible to populate the menu items from the database using procedure?since our project is multilingual we have such a requirement..could someone throw some light on this?

Hi ,
Here is what you asked for.....

Bean to load image item from URL?

Can someone point me to a bean that will allow the loading of an image item from a URL?
Cheers,
Gary

Here is the material:
<p>
the screen shot is here : http://sheikyerbouti.developpez.com/forms-pjc-bean/handleimage/getimage.png</p>
<p>Get the jar file and the form module sample (9.0.2)</p>
Notice that you could also download the image with the File_Transfert.URL_To_Client() Webutil function then load it with the Client_Read_Image_File() built-in.

Show image item from table into form's item.

Hi Friends,
My problem is:
I have 1 table with 2 cols:
eid number
e_pict blob.
I created a form (block based on this table). I'm able to show any valid image file stored in disk into e_pict (declared as image item) using the built_in READ_IMAGE_FILE. and also able to save it in the table test. But if I want to do the reverse process I mean retrieve the image from table's field to the image item of form, it creates problem. I even cannot compile the post_text_item trigger of eid:
select e_pict into :test.e_pict
from test
where rtrim(eid)=rtrim(:eid);
It is giving error:
bad bind variable 'test.e_pict'
Pls help me.
Regards,
Pragati.

If I declare the image field as long raw instead of blob then also the same problem.
I can save the image from file to database through a form but cannot retrieve an image from database to form.
Pls help.
Thanks in advance,
Pragati.

Problem with dimension of an image loaded from a database

Hi,
I succeed in saving image in a MSAccess database with this code:
Image img;
image = new ImageIcon("d:\\prova\\comore.jpg");
img=image.getImage();
try{
int[] pix = new int[img.getWidth(null) * img.getHeight(null)];
PixelGrabber pg = new PixelGrabber(img, 0, 0, img.getWidth(this), img.getHeight(this), pix, 0, img.getWidth(this));
pg.grabPixels();
System.out.println(pix.length);
byte[] pixels = new byte[img.getWidth(this) * img.getHeight(this)*4];
for(int j=0;j<pix.length;j++){
pixels[j] = new Integer(pix[j]).byteValue();
String sql="insert into Immagini values ('1',?)";
PreparedStatement ps = con.prepareStatement(sql);
ps.setBytes(1,pix);
ps.executeUpdate();
}catch(Exception except){
except.printStackTrace();
then, I've load the image with this code:
try{
String query = "select * from Immagini where IDprog = 1";
Statement s = con.createStatement();
s.executeQuery(sql);
ResultSet rs=s.getResultSet();
rs.next();
Viaggio vi = new Viaggio(rs.getInt(1),rs.getBytes(2));
byte[] b=vi.getBytesImage();
int[] intImage = new int[b.length];
for(int j=0;j<b.length;j++){
intImage[j]=(int)b[j];
Image img = createImage(new MemoryImageSource(124,100,intImage,0,124));
ImageIcon imgic = new ImageIcon(img);
jLabel3.setIcon(imgic);
}catch(Exception tps){
tps.printStackTrace();
All works correctly;
but I've two problems:
How do I do to take the dimension of the image from the byte array?
infact in the code up written I've used 124 and 100 as image dimension;
but I can have images of different dimension.
The other problem is:
Why in the image that is loaded are not the same number of colors of the image saved, but only a few, so that the image seems to be out of focus?
Thank and excuse me for my english.
I'm Italian.

Noone can help me?
Thank

Is it possible to write an image data from unix database to windows client?

Hello Sir/Madam,
My database Oracle 11g resides in UNIX. I'm trying to find out if it is possible to pull binary data from unix database and write to a file on windows7 client ?
if so, please share that insight?

Hi,
if you use Oracle forms 10g+ you can use the webutil to do whatever you want between db server and client pc. There are numerous examples on the net, for example:

Sir,
The exception is probably in here.
for ( int i = 1; i <= numberOfColumns; i++ ){
results[i] = resultSet.getObject(i);
System.out.print(resultSet.getString(i) + " | " );
}ResultSet counting begins with 1 but array indexing begins with 0 your code should look more like.
for ( int i = 0; i <= numberOfColumns; i++ ){
results[i] = resultSet.getObject(i+1);
System.out.print(resultSet.getString(i+1) + " | " );
}Sincerely,
Slappy

Populating Drop down from Oracle Database

How do i set the transparency of an image retrieved from a database? (image was stored as blob)

I had stored a png image into a database, when i retrieve it and display it the background is no longer transparent?
I am loading the blob returned from the select statement by using the "loadBytes" method of the "UILoader" class.
Thanx in advance

If you want to stick with adjusting the scale you can do this two ways. Edit the value graph or edit the speed graph.
The problem is that a camera move, a zoom or a dolly in, is not linear and scale is. This means the graphs are not a good representation of what you'll see visually. This makes them hard to use. At a constant rate for scale the appearance is that the increase in size slows down to closer you get to the final value. In other words, as you scale an object up at a constant rate, the visual appearance is a gradual slowing.
A speed graph edited to look like this gives the appearance of a constant rate scale of the layer when you expect an acceleration at the end. There's just not enough granularity in the graph editor or enough control to predictably achieve the results you want.
You'll have better luck editing the value graph to look something like this:
While this looks extreme, you will get closer to achieving the results you want using the value graph. Once again, the amount of control and the resolution of the graph combined with the visual tomfoolery that scaling an object brings with it makes this a difficult way to achieve predictable results.
You select the graph you'll edit by clicking on the second icon from the left.
As I said before, you'll have much better luck getting the look you want if you make the layer 3D and move a camera toward it.

Populating List Item From View

I have two data blocks in my form, one named USERS which contains updateable fields to a table from the view and another data block called CONTROL which are all list items that currently populate on a WHEN-MOUSE-CLICK trigger. The list items work as expected for the WHEN-MOUSE-CLICK trigger. However, my problem is trying to populate the list items based on a selection previously chosen and saved to the table (yes, the values are in the table and are selectable through the view). I have a seperate population for this occurrance in the WHEN-NEW-FORM-INSTANCE at the form level, as well as on KEY-SCRUP, KEY-SCRDOWN, WHEN-NEW-RECORD-INSTANCE, and POST-QUERY at the USERS data block level. The only way the list items populate on a previously chosen and saved value is if you choose (WHEN-MOUSE-CLICK trigger) the list of values and save. From then on, as I scroll through the data retrieved in the USERS data block the corresponding data in the users view shows up in the CONTROL block list items. How do I get my form to initially show the corresponding list item data on form load when it is already in a WHEN-NEW-FORM-INSTANCE and POST-QUERY trigger on form load?
Thanks in advance for any clue to point me in the right direction.

The form is for editing a current student information system user who we will be extracting data for an OBIEE IDM import. All of the fields displayed in the OBIEE_USERS data block can be edited. For the CONTROL block list items I would like them to display the current value chosen for the user displayed in the OBIEE_USERS data block. When the CONTROL block list items are clicked on then a list of values are displayed in which the logged in form user can chose another value which ultimately changes the choice for the user displayed in the OBIEE_USERS data block. This all works fine in my current form except the list items do not display the current user selected in the OBIEE_USERS data block's saved value until the list item is selected, a value chosen, and a save is committed to the table tied to the OBIEE_USERS data block. From that point I can scroll through the OBIEE_USERS block and the list item displays the correct value for the selected user, if there are values (some users have NULL values). I have currently worked around this issue by displaying the fields in the OBIEE_USERS block and only use the list items for the changing selection. I did this because I needed a proof of concept for the pilot roll-out and could no longer wait to figure this issue out (it should be more simple it seems). I am still interested in resolving this as I feel it is a great functionality for the form.

Can I extract images/items from a pdf?

I lost my hard drive! (D'oh!)
But I do have some hi-res pdf files made from the original files (InDesign).
Is it possible to extract discrete components from pdfs? Such as images, text blocks, etc?
It seems like it should be possible, but I'm wondering if one must be a PostScript coder or somesuch.
Cheers!
~Ben

Excellent! Thank you both, George and Steve.
I have CS3, so v8.3.1 or Acrobat. So that process is Advanced > Document Processing > Export all images.
Oddly, it tells me that it can't extract/export vector images. I suppose that means AS SUCH, since it managed to export JPEG versions of images that I know were .eps format. Strange, but true!
Thanks again!
Ben
