Getting BLOB content in C#

Folks,
I've an image file in BLOB container and I need to download the file on client devices. I've both container, file name and image URL as well. Which one gives better performance to get the data from Azure storage by following mechanism.
1. Access BLOB container directly by container and file name with help of WindowsAzure.Storage Library
2. Download the content from URL by using WebClient().DownloadData method
Suggestion please...
Thanks
hibrise

Hi hibrise,
Based on my understanding, there is no difference about performance between two methods.
In Azure Storage Library, You can use first retrieve a blob reference and then call the
DownloadToStream method. While in the WebClient, Call the DownloadData method,it get he array bytes from the URI specificed

Display blob content as pdf file

Dear Expert,
Currently i'm using oracle apex 3.0.1.
I'm having a problem on displaying blob content (from database table) as pdf file on oracle application express but i'm able to save to download the pdf.
Below is the procedure that i used to display blob content,
PROCEDURE lf_html_pdf (pv_image IN VARCHAR2, pv_index IN NUMBER) is
l_mime VARCHAR2 (255);
l_length NUMBER;
l_file_name VARCHAR2 (2000);
lob_loc BLOB;
BEGIN
begin
selecT OI_BLOB,DBMS_LOB.getlength (OI_BLOB)
into lob_loc,l_length
from ord_img
where oi_tno= pv_image
and oi_ti='PDF'
and oi_idx=pv_index;
exception
when others then
null;
end;
OWA_UTIL.mime_header (NVL (l_mime, 'application/pdf'), FALSE);
HTP.p ('Content-length: ' || l_length);
OWA_UTIL.http_header_close;
WPG_DOCLOAD.download_file (lob_loc);
END lf_html_pdf;
I get the error message as below when i execute the procedure above;
Error report:
ORA-06502: PL/SQL: numeric or value error

I'm appreciated if expert can have me on the problem above?

If you're not actually going to use the <tt>l_mime</tt> and <tt>l_file_name</tt> variables then remove these as well. (Although I really think you should set a filename.)

Possible to take a blob content out of table

Hi,
i have a table in which the image is getting storing in the table in blob content.
Whether it is possible to copy that image which is stored in the table to outside, so that i can edit the photo in paint.
It is possible to take that blobcontent of the image out of the table.
If so, how to achieve it.
Regards,
Saro.

Hi Saubhik,
Thanks for the reply, but i get the following error while compiling the code after altered to my requirement.
DECLARE
b             BLOB;
file_handle   UTL_FILE.FILE_TYPE;
file_dir      varchar2(100) := '\ebiz1\proddb\apeximages';
l_blob_len    INTEGER;
BEGIN
SELECT   blob_content
INTO   b
FROM   a_images2
WHERE   employee_number = '048';
file_handle := UTL_FILE.FOPEN (file_dir, 'prasad.png', 'wb')
l_blob_len := DBMS_LOB.getlength (b);
UTL_FILE.FCLOSE (file_handle);
end;This is the error message
ORA-29280: invalid directory path
ORA-06512: at "SYS.UTL_FILE", line 41
ORA-06512: at "SYS.UTL_FILE", line 478

Since i have referred the oracle path only, then also it is throwing the error.

Discoverer portlet error: blob content is empty.

I created 6 disco reports and some are giving error, Failed to retrieve an entry from the cache in the Discoverer Portlet Repository. The BLOB content is empty.
This error only happens with certain users. The users can log directly into discoveer viewer and see the reports. Just not in portal. It also gives me this error randomly and I have to delete the portlet and recreate it. Has anyone else experienced this problem.
BH

I copied and pasted the above code to my jsp. It works fine for me . I get the content correctly. Tried on a ps 7.1
hope the additional character "/>" is not intended
<td>city</td><td><input name="city"value="city"/>/></td>

See BLOB contents on Oracle FORMS

Is there anyway that I can see the BLOB object contents in Oracle Forms? For example, if I have a word document in BLOB, I should be able to open it in Oracle forms. I've already posted this today, but just for clarification, I'm reposting this with exact requirements. My client wishes to see data from a table and in that a BLOB object is one of the columns. For each row, there is a word document, which should also be displayed (or at least a link) on Form. If clicked on the link, the BLOB content, i.e., the word document should get opened. Please let me know if there is any way. Francois was trying to help me, I think this explanation makes it clear for him and also others. I don't have webutil library and my Forms version is 6.0.8.18.3. Please help me soon. I'm in an urgent realease this weekend and need this deliberately. It is not possible to upgrade to newer version for me.
Thanks
Sarma.

In fact, I just had to do this today. It works as expected using an image item on the BLOB column. I am at 10.1.2.0.2, if that makes any difference. Are you positive you have data in the BLOB column? I noticed that after loading a table with image items, I used SQL Developer to look at the table to ensure there was data in the rows. After that, the images no longer appeared in the form. I had to reload the table, then all was well again.

How to get blob image width with ordimage?

Hello,
I have trouble getting image width with ordimage. I have quite the same program for processing images as here: http://spendolini.blogspot.com/2005/10/manipulating-images-with-database.html
so I have declared image files as BLOB files. How can I get the width for the them?
There is a sample from ordimage reference:
DECLARE
image ORDSYS.ORDImage;
width INTEGER;
BEGIN
SELECT p.product_photo INTO image FROM pm.online_media p
WHERE p.product_id = 3515;
-- Get the image width:
width := image.getWidth();
DBMS_OUTPUT.PUT_LINE('Width is ' || width);
COMMIT;
END;
the ORDSYS.ORDIMAGE is used instead of BLOB here. when i do the same then i can't select BLOB content into the ORDSYS.ORDIMAGE variable. And otherwise I can't use the getWidth with the BLOB variable.
Can anybody help please?

Hi,
the column blob_content is not suitable for storing into v_image2 because variable v_image2 is of type ORDSYS.ORDIMAGE and the column is BLOB.
I used the following method instead:
declare
image blob;
attributes clob;
img_mimeType varchar2(32);
img_width integer;
img_height integer;
img_contentLength integer;
fileFormat varchar2(32);
contentFormat varchar2(32);
compressionFormat varchar2(32);
begin
DBMS_LOB.CREATETEMPORARY(attributes, TRUE, DBMS_LOB.CALL);
select img
into image
from image_repository
where id = 0;
ORDSYS.ORDImage.getProperties(image,
attributes,
img_mimeType,
img_width,
img_height,
fileFormat,
compressionFormat,
contentFormat,
img_contentLength);
dbms_output.put_line(img_mimeType);
dbms_output.put_line(img_width);
dbms_output.put_line(img_height);
dbms_output.put_line(fileFormat);
dbms_output.put_line(compressionFormat);
dbms_output.put_line(contentFormat);
dbms_output.put_line(img_contentLength);
DBMS_LOB.FREETEMPORARY(attributes);
end;
try adapting this code and think about the possibility of "caching" image properties, because it takes some time to retrieve them every time.
Bye,
Flavio

Get all content from iTouch to a new computer.

My problem is very simple to explain, but I find no solution.
My old computer is damaged and I cant use it anymore. So I bought a new one and I want to get all my stuff from the iTouch to iTunes on me new computer. After installing iTunes I actived in iTunes my iTouch for iTunes. In iTunes I get the massage that now two computers are actived (5 are possible).
So I connect my iTouch with the wire to my computer and I get the massage that my iTouch is logical connected with an other iTunes libary. I get the only possibility to delete my iTouch and syncronize it with the content of the new iTunes libary.
*My question is how can I get my content from the iPod touch to iTunes on my new computer?*

Hi,
Welcome to Apple discussions.
So, in a perfect world, you would restore your library of valuable music from *your backed up files* to the library on your new PC, you know, the ones burnt to DVD/CD or on an external HD.
This is the way iTunes works, it makes it perfectly clear and actively encourages users to *back up your music*.
The iPod touch is not a back up device (nor is it advertised as one) it is a music player with a volatile memory that could actually disappear at anytime so it should not be trusted as a store for valuable files.
To salvage your music you will have to use some 3rd party application on your PC/Mac (you fail to say) such as [Touch Copy|http://www.wideanglesoftware.com/touchcopy/index.html], Google for other options. This is not guaranteed to work but hopefully you will get your music back.
Then back up.
Good luck,
Dud.

The songs that you downloaded on the iPad can be transferred to the computer when you sync with iTunes. For the music from your cousins computer - if they were purchased with his Apple ID - you can't sync them to your iTunes account.

I am thinking of buying a MacBook Air and am wondering how to get the content of my iPad into iTunes.

I have iTunes on an old pc and am thinking of buying a MacBook Air. I am wondering how to get the content of my iPad on to the Mac as I know that sync only happens in one direction, from pc to device. I assume therefore that when I attach my pad to the new Mac it will sync to an empty iTunes and I will have lost all the content of my pad. I know I can restore purchases, but what about contacts, calendar, photos and music not purchased from apple. I have a fairly recent backup on a pen drive but it is a usb2 device and is formatted for a pc. Any advice would be appreciated.

Do I copy my media library or from a backup. I have a backup on my pc and on an external drive. This drive is usb2 and formatted for windows so I can't connect it to a MacBook Air to make the transfer. Equally I don't think there is a way to connect the 2 computers via a cable ie usb2 one end and usb3 the other. Will the computers talk to each other via wifi if I enable home share although I think this is only for music which still leaves contacts, mail etc.
I am sorry to be such an ignoramus but any further help would be appreciated.
