Image: poster of local disk, download server and display the server file system
Hello
I use jdev 11.1.2.4.0...
The requirement is that users want to upload images to their local drive for the drive on the server and they would like display of server disk images later.
We do not want to save the images in the database. I'm not sure what should be the solution; However, I intend to...
1 create a table to keep information from images - image_id, image_location (server drive), image_filename
2. create a page where users can enter image information and specific file on a local disk name (I think I'll use inputFile component) and provide the Preview button to display an image on the screen before saving. To record data is to save the information in the database and copy an image file on the disk on server (the location for image files is predefined.)
3. create another page where users can browse the database information and display an image for a selected record getting from the server.
I need suggestions on...
1. how to display an image on the page of the local drive?
2. how to copy a file on a local disk to a server?
3. how to display an image on the page of the drive on the server?
Thank you.

When Timo records the images in the database, you save it in the file system (examples on how to do this Java are available much if you just Google for it). Similar to Timo you then use the tag image to display pictures. The difference is that you can directly add the URL of the database table.
The advantage of using a database to host images, it's that you're not although dependent on files server structures

How to read and display the .ai file in CS4 SDK?
Hi all
I drew an own and saved the socument as file traingle.ai.
Now, I want to read/open the traingle.ai file in the plugin.
[Lets say, I want to read this file based on GoFilter ()]
Is there an API to read file .ai in CS4 SDK? and display as well?
If you mean autonomous (outside Illustrator) the answer is no. The SDK is reserved for the plugins loaded into Illustrator. If you want to open a file from Illustrator that is perfectly doable if. I think that AIDocumentList:: open() that will handle.

Search a directory of data and display the data that is within the range of dates
Hello
I have a full idrectory of data from overtime, and I think of search in the directory and display the data files for specific dates. I only started this encoding yet but I figure I'll take the brain of some SMEs here labview and start in the right direction. My goal is to go through a comprehensive directory of data taken for a month or MORE csv files and select the data to process and display office files the date of its registration. If I take the data of last week, last month or last minute, it should just treat as an exact or more.
Please help me get started on the right foot
End date will be probably greater than the start date, right? So, end date must connect at the entrance to the upper limit. Then wire in the range? to the conditional terminal of a tunnel of conditional indexation.

Remove temporary files from the local disk c/documents and settings/user/localsettings/temp name
By definition, this folder should contain only the elements you don't need. If I understand correctly, this temporary folder is a place where temporary files are stored during program facilities and the facilities. However, I have seen references other sites to help saying some programs can store folders and files.
I do my own temporary file elsewhere, name it accordingly and move all the files in the temp folder to the new folder. Use your computer normally for a while, and if nothing complains about missing files, you have a good indication that none of the moved files are important and should be safe to delete.

When I download compressed files, they go to the local level > temp location, when I extracted all the files, they are sent to the My Documents folder. Can I go to local > temp location and delete the zip file? Knowing that I still have the data in the My Documents folder.
Once they are checked, of course. If you want to keep a backup, you can move the zip file in your documents folder.
In fact, you can delete everything in the temporary folder that is not currently in use. Best time to do this removal is immediately after the start, before launching other applications.

With previous versions, I could press control (mac) and click on a layer, and he would choose this graph, what form it was. Then I could go to image-culture and reframe the entire file down to that size. Now, this feature is missing. What is the new way to do this?
This is the command key, not the control key for a Mac that you use on the layer.

To download PDF files, you have nothing else except a web browser.
However, to open the pdf file that is downloaded, you certainly need to download Acrobat Reader: Adobe - Adobe Acrobat Reader DC DistributionKind regards

How to download files from the database file system.
Hello everyone.
I m trying to do a procedure to download a PDF file that is stored in the file system of the server of the database and not inside the database. The established procedure is the following:
create or replace
PROCEDURE PRT_PR_DOWNLOAD_FICH (v_file_name VARCHAR2
)
AS
V_LENGTH number;
Lob_loc Bfile;
BEGIN
Lob_loc: = bfilename ('DIR_OBJ', v_file_name);
V_LENGTH: = dbms_lob.getlength (Lob_loc);
owa_util.mime_header ("application/octet ', False");
HTP.p ("Content-length: ' |") v_length);
HTP.p ('Content-Disposition: attachment; filename = "" | ") SUBSTR (v_file_name, INSTR (v_file_name, ' /') + 1) | '"');
owa_util.http_header_close;
wpg_docload.download_file (Lob_loc);
END PRT_PR_DOWNLOAD_FICH;
This procedure receive the name of the file to download and use the wpg_docload.download_file () function. The DIR_OBJ is a directory with path from the server to the folder that contains the files I want to download.
When I run this procedure I get the error: "Internal Server Error".
Can someone tell me what I am doing wrong and if it is the best way to download a file directly from the database server file system?Hello Pedro,
Just out of curiosity, I tried your example ;-) It works very well in my environment! (Oracle 10g with OSH and Apex 3.1.2
But: I had to grant READ permissions on my directory object to APEX_PUBLIC_USER!(1) I created a "test.txt" document in the directory corresponding with my EXPDIR directory object. 'Oracle' user needs read on the file & document permissions!
(2) give APEX_PUBLIC_USER necessary READ rights on the directory object:
grant read on the directory expdir to apex_public_user;
(3) create the procedure:
CREATE OR REPLACE PROCEDURE MATTHIASH. PRT_PR_DOWNLOAD_FICH (v_file_name VARCHAR2)
AS
V_LENGTH number;
Lob_loc Bfile;
BEGIN
Lob_loc: = bfilename ('EXPDIR', v_file_name);
V_LENGTH: = dbms_lob.getlength (Lob_loc);owa_util.mime_header ("application/octet ', False");
HTP.p ("Content-length: ' |") v_length);
HTP.p ('Content-Disposition: attachment; filename = "" | ") SUBSTR (v_file_name, INSTR (v_file_name, ' /') + 1) | '"');
owa_util.http_header_close;
wpg_docload.download_file (Lob_loc);EXCEPTION
WHILE OTHERS THEN
HTP.p (substr (dbms_utility.format_error_stack (): dbms_utility.format_error_backtrace (), 1, 4000));
END PRT_PR_DOWNLOAD_FICH;
/(4) Grant execute rights on APEX_PUBLIC_USER of this procedure:
GRANT EXECUTE ON MATTHIASH. PRT_PR_DOWNLOAD_FICH TO APEX_PUBLIC_USER;
(5) Finally, try if download document works well:
http://
: 7777, pls, apex, MATTHIASH. PRT_PR_DOWNLOAD_FICH? v_file_name = test.txt I would like to know if it works!

Want to access a SOAP service and display the data in the external list
Hello
I could see a WCF Service via the type of external content successfully. Now I want to access a SOAP Service and display the data in an external list in Sharepoint 2010. I am able to create a data source with success with the SOAP service, but how to display the data in the external list as external list uses only as data sources for external content types.
Also with WCF as external content type, it is only on WCF services or any kind of web services can be added as an external content type.
Any help would be appreciated.
Thanks in advance
