Images: displaying from the file system

I have the instructions for loading images into a database column. However, for my prototype, I want to read leave the images in the file system and store the filenames in the database. Then I want to create a form to display the images in an 'art gallery' kind of format, like a column for the picture, a column for a description, and column for a checkbox, so the user could say 'I want this one, this one, and this one.' What's the best approach for this kind of thing?

Have you looked at the sample application? I think it has a table just like that, I don't have it installed anywhere anymore, so don't know off the top of my head.
One way is
your pictures table would have a format like:
ID, PICTURE_NAME, DESCRIPTION
your report is then:
select htmldb_item.display_and_save(1, id) id,
'< img src = "/i/your_directory "'|| picture_name ||' " < /img > ' picture,
htmldb_item.checkbox...

Strategy and Process on how to best enqueue from the file system

I have a single database that must accept BFILES from one location via a directory folder, http text documents via proxy server, and unstructured XMLTYPE CLOB from another database.
I have created an ANYDATA queue, and will try to transform the dequeued output to XMLTYPE payloads for a pl/sql callback.
My problem is how to monitor both the file system BFILE folder, and the XMLTYPE CLOBS, to automatically begin then enqueue process. The queue would have to accept from (1) to anynumber of files, and given that requirement the use of an array batch is what I would like to use, but need to populate the array.
Any help would be most appreciated.
David

Thank you for the quick reply.
The database version is 10.2.0.3.
There are three sources of documents coming into the system.
Source 1: Outside entity (in-front of a secure firewall) who must place their XML (XSD compliant) files on a shared file system server (the BFILES).
Source 2: Internal entity (behind firewall) who publishes their XML files to a defined database directory on the database server.
Source 3: Enterprise Intranet contributors submitting their individual files via url.
On entry for each file they must be validated for XSD compliance then if passed submitted to the main enqueue for propagation to 5 additional process queues with separate callback procedures.
If reasonably possible, separate agents of some sort would "listen" at each folder location, then begin the enqueue process when either a batch of files or a single file is placed in the directory folder.
AQ itself has no such mechanism to monitor locations, and a scheduled job makes sense - however the job would have to continuously run given the very short processing requirement. However, using DBMS_SCHEDULER may be the best solution given ALL rhe requirements.
Thank you for your professionalism - I appreciate the assistance.

How to retrieve images from the file system in Portal Forms?

Portal 3.0.9.8.0
In a Portal form , there is a field named ID wherein a value is entered. Say the value entered is 5 , how can we get the image named 5.jpg
from C:/images/ folder and get it displayed in the form ? The images are not stored in the database . Depending on the ID field value , we
have to retrieve the image.
Thanks .
Neeti.

Hi Neeti,
This is what I did :-
Steps:-
1> I created a procedure named get_image in the application schema as :-
create or replace procedure get_image
p_id in integer default 1
is
begin
htp.p('Image Id='||nvl(to_char(p_id),'No Image Id'));
htp.br;
if p_id is not null then
htp.p('<img src="C:\images\'||p_id||'.jpg">');
end if;
end get_image;
2> Created a form on the procedure get_image.
3> Run the form and for p_id field, enter the image id, and click on Submit - the image will be displayed.
Hope this helps.

My prog's work fine. How to call from the file system?

Hi,
I currently have an application that works great. Its all javabeans and its called from a JSP page. My question is, I call like this:

OK...This is an example. If I can get this to work, Im good to go.
I call this via:

Image: display from local drive, upload to server file system, and display from server

Hello,
I am using jdev 11.1.2.4.0...
The requirement is that users would like to upload images from their local drive to server drive and they would like display images from server drive later.
We don't want to keep images in database. I am not sure what the solution should be; however, I plan to ....
1. create a table to keep an information of images -- image_id, image_location (server drive), image_filename
2. create a page where users can enter image information and specific filename from a local drive (I think I will use inputFile component) and provide the preview button to display an image on screen before save it. To save data is to save information to the database and copy an image file to the server drive (the destination location for image files is predefined.)
3. create another page where users can browse information from the database and display an image for a selected record by getting from the server.
I need suggestions on...
1. how to display an image on page from the local drive?
2. how to copy a file from a local drive to a server?
3. how to display an image on page from the server drive?
Thank you.

Where Timo saves images to the database, you save it to the file system (examples on how to do this from Java are available plenty if you just Google for it). Similar to Timo you then use the image tag to display images. The difference is that you can directly add the URL from the database table.
The benefit of using a database to host images is that you are not dependent on file server structures though

Me again,
A friend suggested that I do a system restore.
I did a search for system restore in Windows 7 and got a very intuitive menu.
I selected an earlier system restore point and executed the restore.
After the computer restart I reloaded Firefox 5.0 and the Ask.com problem was corrected.
My friend says this approach may work about 25% of the time to fix this kind of problem. In my case it worked and I am happy.
Thanks all.

If I secure my browser using CISecurity's baseline for Firefox, can I copy all the ".js" files from the hardened system to another?

I own multiple systems. I have hardened one browser following the guideline provided by CISecurity. Instead of repeating all the configurations performed on that one system, can I just copy all the ".js" files from the secured system to my other systems?
The ".js" files can be modified using a text editor. Is there a way to lock down these files to prevent modification?

Dear Joel
i know two ways to prevent browser from caching your files
First : The Hard way
just add ? +Math.random() in the end of your file
Like this :
in HTML :
<script type="text/javascript">
(function(){
     var e = document.getElementsByTagName("script")[0];
     var d = document.createElement("script");
     d.src = "index_edgePreload.js?"+Math.random()+"";
     d.type = "application/javascript";
     d.async = true;
     d.defer = true;
     e.parentNode.insertBefore(d,e);
</script>
instead of this Line in HTML that created by EA :
<script type="application/javascript" src="index_edgePreload.js></script>
Disadvantage : you should do this for all of files you want to prevent from caching
===================================================
Second : The easyest way
You Should have Access to .htaccess file in your Server
Open your .htaccess file and paste these codes in it :
ExpiresActive On
ExpiresByType application/json "access plus 1 seconds"
ExpiresByType text/json "access plus 1 seconds"
ExpiresByType text/plain "access plus 1 seconds"
ExpiresDefault "access plus 1 month"
you can type what ever type of file you want to prevent from caching in browser
Advantage : after do this in your .htaccess file all files with the type you want will not Cache in your browser
Easy is'nt it ?

Linux Mint 17, migrated from Win7: Verify that you have enough disk space, and that you have write privileges to the file system, then try again.

I get this error message (The messages could not be filtered to folder 'Generic Folder' because writing to folder failed. Verify that you have enough disk space, and that you have write privileges to the file system, then try again.) popping up on many, though not all of my incoming filters. I recently migrated from a Windows 7 installation to a Linux Mint 17 system.

I did give it time to run through everything when I initially migrated, and it frequently will sit open for 3 to 4 hours while I'm working on other projects.
The 'Generic Folder' represents sorting folders in my main mail account in Thunderbird. For example, my mail which is listed to filter into my 'Amazon' folder is sorted there with no problem, while any mail designated to be filtered into my 'Games' folder prompts the above error massage.

Why does moving the mouse over an IMAQ image display slow the GUI down so much?

I have a large application with several vi's running simultaneously under labview 8.6.1. When I mouse over an image display control in one of the vi's, everything slows down a shocking amount in all the other vi's. The windows task manager does not show a large increase in CPU use. My pc is has a quad cpu with 4GB of RAM, and the CPU and memory loads do not appear to be terribly taxing to the system. However, many of my vi's apparently come almost to a standstill if I just move the mouse in a circle around my image control.
This looks like it is largely a GUI display issue. If I make a new vi and put a while loop in it that only displays the iteration loop number to an indicator, I can see the iterating occurring, then stopping totally when I mouse inside the image display control. When I stop moving the mouse inside the control, or when I move it outside the control, the interation loop number jumps up, as if it had been incrementing behind the scenes the whole time. So only display of the interating was halted.
This problem occurs even if the vi with the image control is not executing. If the vi with the image control is open but not running, and I mouse over the image on it, the other guis all come to a screeching halt.
Does mousing in the image display control really utterly crush all other guis in all other labview windows? Is this an issue inherent to the image display control? If so, is there anything I can do about this?
Also, this issue is not entirely limited to display. I started looking at it in greater detail because this issue also exposed what I think is a race condition in my code. I have a vi that acquires an image from a ccd and puts it into an IMAQ image.ctl. This image then gets passed up to a vi up the call chain, and is put on a queue and sent over to be de-queued by a vi that has the image display control. Here's the kicker: when I mouse over the image display control, the image successfully gets acquired inside the subvi, and if I probe the wire leading to the output IMAQ image display.ctl, I see the image. If I simultaneously probe the wire coming out of the subvi one level up the call chain, the image gets lost about half the time. This only happens if I am mousing in the image display control IN A TOTALLY DIFFERENT AND SEPARATE VI. If I bump up the priority of the ccd image acquisition vi to 'highest priority', the problem only happens about 1% of the time, and I really have to mouse around to make it happen. Still, it's disturbing that mousing in the GUI in one window results in a failure of a separate subvi to simply pass an image up the call chain. I understand that IMAQ images are referenced rather than passed by value, but I don't see why there should be a failure to pass the image up the call chain. I've looked for a race condition, but can't find one.
Eric

I have finally been able to replicate the behavior that you are seeing on another computer once the image was large enough. Here are a few notes about this behavior:
First. The UI only slows down when the images are large, 16 bit images. The reason why this is unique to 16 bit images is that they can only be displayed on the front panel as 8 bit images. The workaround that Weiyuan suggested to change the 16 bit display mapping hints towards the root of the problem...that any time a mouse runs over the indicator, Windows asks the entire image to re-draw (having a separate indicator overlapping the image will create the same behavior). With a 16 bit image, not only does the image have to re-draw on the screen but the 16 bit pixels need to be mapped to 8 bits. When setting the 16 bit display mapping to Full Dynamic, this requires mor computation/pixel than 90% dynamic or one of the other mapping schemes.
This is expected behavior if your program is running and you're trying to display a large 16 bit image. To fix this behavior there are a couple options:
Change the 16 bit display mapping to something other than full dynamic. You can choose which 8 bits to display or if you want to map the bits.
Resize the image just for viewing purposes on your front panel (since you aren't going to view every single pixel of you image on the screen). You can use the IMAQ Resample.vi to do this. This will allow you to take your 1500x1500 pixel image and only display a 500x500 pixel version.
If you are interested in viewing small details of the large image, consider just displaying a smaller region of interest at a time.
Let me know if any of these solutions work for you. Good luck on your application.

Error 64 is being returned which is simply "the network name is no longer available".
There can be a number of reasons for this from SMB compatibility issues (2003 servers wont support SMB2), to the expected and actual computer name of the boxes don't match (tries to authenticate with server.tld.com when the actual name is srv-01.tld.com and
you just put a C-name in). I'd start from the top: Try opening said share from the Primary Site server as that's the box doing the work. Verify the IP and computer name is legit and that no one has played ACL games between the two systems (remember
RPC only initiates/listens on port 135 but established connections are up in the dynamic port range).
At the end of the day it's an issues "underneath" SCCM, and not an SCCM problem specifically.

IPhoto9: "library could not be opened because the file system of the library's volume is unsupported."

Can please anyone help me with this issue.
After upgrading from iPhoto8 to iPhoto9 my library won't open anymore. I have stored all my pictures on a NAS (Buffalo Link Station Duo). It all worked fine but since upgrading to iPhoto9 I do have the following problem:
When opening iPhoto I receive a message that the library needs to be updated. I assume that iPhoto should just do this sort of automatically in order to upgrade to iPhoto9.However, next message I receive then is
"The library could not be opened because the file system of the library's volume is unsupported."
Apple support so far does not seem to be able to solve my issue. Anyone else having had the same issue and having a solution to this?
Thanks a lot for your help.

There is no solution.
IPhoto needs to have the Library sitting on disk formatted Mac OS Extended (Journaled). Users with the Library sitting on disks otherwise formatted regularly report issues including, but not limited to, importing, saving edits and sharing the photos.While you have been lucky to date, many folks with a library on a NAS found that it worked for a while and then the problems started.
Workaround: Put the Library on a Disk Image formatted Mac OS Extended (Journaled) and store that on the NAS. But the real solution is to use a properly formatted disk for the Library.

Autodetection failed on your first image, in both your previous kernel installs:
[2011-07-04 16:14] find: `/sys/devices': No such file or directory
Which means that sysfs was not mounted. You should be able to boot from the fallback image, which does not use autodetect. Figure out why /sys isn't mounted, as well, and fix that.
This is also a somewhat crappy bug in mkinitcpio that lets you create an autodetect image that's useless. It'll be fixed in the next version of mkinitcpio that makes it to core.

Gif - file help: i don't want to read the gif each time from the file.....

Hello there guys,
i'm making a game and therefor i need to read a gif file like 20 times.
i don't want my program to read the gif each time from the file, but only once.
so i load it into an image or something?
cuz opening the gif 20 times from my hard disk is a lot of time loss....
opening it once and store it is much more efficient
thx in advance
plz help me out, cuz i don't really know how to do it.
(in Delphi it's easy, but Java......)

          JLabel label = new JLabel();
          label.setIcon(image);
          this.getContentPane().add(label);
          label.setBounds(10,10,100,100);
and there i see my image :-)
but 1 more thing, should i display all those blocks (images) on an applet, or should i use something else? (like what??)
a sort of frame?
because later on i have the field where all the blocks are in, and i have an area surrounding it, displaying all kinda information about the game, like how many lives remaining....
can i put 2 applets in eachother? like applet1 is the parent of applet2?
or should i use something else?
plz help me, cuz java is kinda new to me i see....
in delphi i just used 2 forms, form 1 with the blocks, form2 with the rest of info, and also being the parent of form1
thx again, soon i can help ya guys too, i hope..
