i am migrating from forms 6i to forms 10g but i am facing a problem. when i enter to my new form and i try to navigate thru the items with my mouse the validation of the item doesn't work properly. the cursor change position but the functionality works like it is still in the first item. the validation work when you use enter or tab.the same thing when you try to fetch the LOV, the LOV of the first item is populated not where the cursor is positioned.

how to know when a user was navigating away from the current open form (and I wanted to prevent the navigation with a dialog box) because they had entered a new URL in the address bar and were trying to navigate to it? I've seen a reference to it from an ADF perspective -> [URL]
but was wondering how to do it within Forms?
The reason for this is that i would want to prompt the user to confirm that they wanted to exit the form as potentially they would have a record (in the form) flagged as being updated and as such no other user (including themselves) could susbequently access it. So, I'm basically wanting to know if there is a way to catch the fact that the user is about to navigate to another web page.
Is it by using javascript and if so, how would it be implemented?

I have a folder "c:Images" which has around 5 image files they all are Tiff Images. now from forms i want to open this images one by one.
example:
file 1: SIGN.TIFF
file 2: FORM.TIFF
file 3: FORM_1.TIFF
File 4: FORM_2.TIFF
File 5: PHOTO.TIFF
I have the form and in that I have only one Image Item and two buttons with name "Previous" & "Next"
Action to be Done:
-> Initially when i start form SIGN.TIFF has to open.
-> when i press next FORM.TIFF has to be replaced with SIGN.TIFF
so on...
Note: There is a chance of keeping 10 more files.
How can this be achieved in forms.

I have seen many times that people are confused for how to save and retrieve images in Oracle Database from forms. Here I have created a sample form. All the coding is there. And also required scripts are also written in this post. Please download the form create the scripts and run the form.
Here we go:
Database : 9i
Forms : 6i
Create Scripts:
CREATE TABLE DOCS_COMP_DOCUMENTS
(
DOC_ID VARCHAR2(10),
DOC_NAME VARCHAR2(100),
DOC_SCANNED_COPY LONG RAW,
FILE_NAME VARCHAR2(50),
FILE_EXTENSION VARCHAR2(3)
)
[code].......
Note: This Procedure is to find the file name and extension and store it as well in database. Create this procedure in database.
To retrieve images just press F7 & F8 in forms
Download the attached .fmb module and run it.

I am trying to retrieve images from the file system, but the open dialog box is not popping up for me to choose which file i want. It does nothing gives no error. Just says record 1/1 on the message bar at runtime.
I have two blocks on the module. One is the lobs_table block and the other is the control block. On the control block i have a when-button-pressed trigger on an item. And here is the code below.
Declare
jpg_image_dir VARCHAR2(100) := 'C:UsersajayiaDesktopMe_pics';
photo_filename VARCHAR2(100);
BEGIN
:System.Message_Level := '25';
[code]......
I don't know the code to use to get forms to bring up the open dialog box.

I have an issue with an OLE-Container (ITreeView).
I have already a form with the treeview (database no necessary) with some nodes added manually.
All this nodes have checkbox and style properties, drag and drop (drag automatic and drop manual).
I added also to the form an OLE-Container for the listImage and put into the container the images that i need.
I put checked the father and when it is true then a variable into the declaration of the check of the childrens change and the child nodes are checked too, but when i do it manually nothing happened.
What I want to do is the next thing: I want to be able to drag and drop in every place of my tree to change the positition between the nodes of the node father and to change it also with childnodes of other parent. To Put an Image next to each node (how to call the images that are inside of my imagelist) When I checked the parent then check all the child nodes of it.

Can a Oracle Function return Images? I have been getting and able to read lot of solutions but still unconfirmed. As in certain forums it has been mentioned that the difference between procedure and function is that. With procedures you are able to return images but not with function.

We have a report that is using a blob and in that blob is a text string that is in base64. The text string is converted into an image via a function that is a java class. The function works well when executed from SQL Developer, PL/SQL Developer, and other tools either good or bad image.
The problem is that in the reports it crash if the image is bad (no error message). In the report how do I make an exemption if the image is bad to just return null? This way the report does not crash.

We are re-designing our App and we have a critical question, what's the best way (in terms of performance) of using TIFF images (about 20K size) with Oracle.
Currently we have a Windows shared file server and we create the tiff images there under a huge directory structure (like /images/ddddmmyy/aa/bb/001, then /images/ddddmmyy/aa/bb/002, etc, etc). Our database is usually in LINUX version 10, 11 or 12. We create about 200,000 images per day, keep them for 60 days and then remove that structure.
Our Web app (developed with .NET) reads those images just to display them on a Web Session (IE).As you can see, what we are doing now works fine. But network sometimes is an issue and also it's hard to keep synchronization with our DR server, backups, etc.
Are we taking the correct approach? It would be better to have the images in CLOB or BLOBS for better performance? If so, As I mentioned, performance is the KEY FACTOR and the most important item to consider in this design.

i have to update the blob column in a table with new image.
we have a table with 10 columns in which one column is 'image' as BLOB data type, and one more column with "image_name " and has more than 1000 rows.
I have a 300 images which I need to update in "image" column .
I need to match the given images name with "image_name" column, if row is present in the table than update the "image" column with the given image.
I search and found almost same code to insert the image in new table with a procedure, I mean code is to call the procedure, ( by passing image name and image directory)
Is there any way that we will check all the image given in the directory, if that image_name is present in the table then update the image provide me a sample code for this

I was having a play with an icon menu system on apex mobile using a list template as described by Peter Raganitsch.Improve the APEX mobile Theme – Part 3 | get along with Oracle and APEX Though instead of using images from /i/, I wanted to source images from the database using apex_util.get_blob_file_src
However the rendered output begins
<img src="/i/apex_util.get_blob_file? If I run the following on page load
$('img').each(function() {
$(this).attr('src', $(this).attr('src').substr(3));
});
I get the output I want but the console is still full of errors and I feel very dirty.of displaying icon images from a report in the mobile interface?ie - similar to an iconic interactive report.

I have a web page written by pl/sql and html which some jpg files are published. Currently they are linked by html from a directory source. There are almost 70000 files which makes 1.15 gb. I want to store them in our oracle database but I have never done this before.
What I want to learn is how will be the performance for selecting from many jpg files with select statement and how much space would they keep in the database?

I have recently upgraded our test APEX environment from 3.2.1 to 4.1.1.00.23. Everything went smoothly - I have only one small but annoying problem. In both administration and administration services some background graphics are not displayed. This issue occurs only under Mozilla Firefox (in MS IE it OK). The application frontend is OK in both browsers.
Under Firefox, I inspected the sourcecode in Firebug and the relative links to images. e.g.
background: url("../apex/builder/bg-region-darkblue-r.gif") no-repeat scroll
show message "Failed to load the given URL".
somehow related to the fact that our application is accessed via apache proxy. Because when I open the administration and/or administration services page in FF directly on the server, it displays correctly (incl. images).
But the network (Apache proxy) configuration is exactly the same as in the previous version of APEX where we had no problem. Something must have changed in the sourcecode of the new version.

I have an Oracle 10g database, on the App Serv I have an image file that has 20,000 .jpg files that has an id number as each image name.I have successfully queryed the image file and posted one image to my web page matching the image id number.
sample:
select substr(spriden_last_name,1,20)||', '||
substr(spriden_first_name,1,20)||' '||
substr(spriden_mi,1,1) stname,
'<img src = "/images/&1..JPG" width="400" height="400"/>' pic
from spriden
where spriden_id = '&1'
/
the &1 is the matching id number that is input from the user.My task now is to select multiple images using a department field in the spriden table to pull the needed id numbers.I have not been successful in the proper format to pass the id number to the <img src field.

We are planning to move BLOB images in our DB to BFILE to reduce the time and size of backup.
So when we have a physical dataguard setup, can we configure data guard to copy the OS level BFILE's to the DR site?
