I have a very large array of floating point numbers which I am trying
to
store in an image type field. I am using the dataset class to
directly enter the data but am having trouble trying to get this type
into the image field. I guess the question is how do I get a large
floating point array into an image (byte)field of a database using the
dataset class for new row entry.
I am using the 3-tiered architecture design (presentation, business laws, and data acess layers). I am stuck on how to send the image the user selects in the upload file control to the BLL and then to the DAL because the DAL does all the inserts into the database. I would like to be able to check the file type in the BLL to make sure the file being uploaded is indeed a picture. Is there a way I can send the location of the file to the BLL, check the filetype, then upload the file and have the DAL insert the image into the database? I have seen examples where people use streams to upload the file directly from their presentation layer, but I would like to keep everything seperated in the three classes if possible. I also wasn't sure what variable type the image would be in the function in the BLL that receive the image from the PL. If there are any examples or tips anyone can give me that would be appreciated.
I am using an image datatype to store multiple filetypes includeing plaintext data. it works except for pdf Data. When I retrieve the the filecouldn't be opened in acrobat reader and the file was 3KB bigger than theoriginal.Any suggestions would be helpful.
I'm storing thumbnails in SQL CE and accessing them from my WPF application. The save seems to take place ok and there's binary data in the image field however when it comes back out it appears to be corrupted somehow. Can someone have a look at the code below and verify I'm doing the conversion correctly before storing in my image field? Thanks!
Just starting to investigate this. I need to store digital pictures in my database for use in claims and disputes. I have played a bit with the image datatype but notice that one picture takes up 1Mb as a TIFF and 3Mb as a JPEG. Does anybody work with this stuff and if you do what is the best picture format to use in regards to keeping clarity but minimizing size used in the db. Is there any load conversion routines that would shrink the size of the file.
Any suggestions or comments on this topic are appreciated.

Hi,This is driving me nuts, I have a table that stores notes regarding anoperation in an IMAGE data type field in MS SQL Server 2000.I can read and write no problem using Access using the StrConv function andI can Update the field correctly in T-SQL using:DECLARE @ptrval varbinary(16)SELECT @ptrval = TEXTPTR(BITS_data)FROM mytable_BINARY WHERE ID = 'RB215'WRITETEXT OPERATION_BINARY.BITS @ptrval 'My notes for this operation'However, I just can not seem to be able to convert back to text theinformation once it is stored using T-SQL.My selects keep returning bin data.How to do this! Thanks for your help.SD
I am storing my upoaded images in sql server. However, if the user does not upload an image, a broken link is shown in the page. All that shows up in the DB field is <Binary>.
Can we set this field to a default value? Is it possible to view this binary data.
I would like a default blank gif to be returned if no image is uploaded.
I have .wav file data stored in an Image field in sql server 2005. Do you know of any sample code to play the sound in a windows forms app (C#)? (This post is just a lame effort to avoid about week of experiments.)
Hi I am currently working on an application that uses a stored procedure to retrieve data from a database and then display it in a web page. My problem is that some of the data in the database will be images, I am currently putting in test data to test my code/procedures my problem is how do I put in test data for images, when I am finished I am going to add an admin section that will allow me to add images that way but how do I go about adding them to the database until then? I have set the field to the image data type but have no idea how to relate this to an image on my server? Thanks, Adam
1. How can I upload new pictures into the database through the browser. 2. Can you describe how the new picture of the product would be uploaded into the database. 3. How do you handle different formats that pictures come in gif, tif, jpeg, etc.
4. How can you say that SQL server does support images well, because on microsoft site they loaded up the satellite data of the earth into sqlserver which is only picture data
What are the negatives, challenges and issues going to be if we choose to store 300-1000 GB worth of image, xml and PDF files (avg size 1 mb) in SQL server 2005 db.

I did some quick Googling and didn't find the article of my dreams here. Any experience with storing files in the db in 2005? Any opinions?
Here's the deal. We have our new 'Enterprise' software being designed and written in St. Petersburg (not FL) and I'm reviewing the design for dealing with letters and forms that are generated as hard copy from our business (by the thousands per month) and sent to clients for review, signature etc. Then they are returned by fax or snail mail.
The current design has all of these being stored in image data type columns in the database--storing saved files of the actual outgoing stuff and saved files of the stuff that comes in (scanned copies or the files from our fax server).
This screams 'BAD IDEA' based on our experience doing this in SQL Server 2000. We get things like 23 page faxes from Dr's offices, large packets of FMLA forms returned, etc. In 2000 they tended to get rather large when stored in the DB and caused us all kinds of headaches when Microsoft changed how it recognized and displayed certain types of files, e.g. tiffs.
Further, the outgoing stuff is largely boilerplate with added fields from the db--name, address, a few dates. My proposed design for outbound notifications and forms was to keep only references to the template used, the date created, and an id to link it to the personal info of the schmoe to whom it was sent--essentially, store which document template and then just enough data to map to the variable content that is pulled from the db. Then you can recreate the file that was printed and mailed at any time in the future, but you don't actually save the .doc (or Word .xml) anywhere, not in the file system, not in the db.
The current developers feel this is way too much work to design--and it is certainly more effort than just generating .docs/.xml files via a merge with Word and then stuffing those into the database. They also argue that having them in the db makes them 'more secure' and more 'accessible' to users around the globe.
Does anyone know if the image storage is any better in 2005 than 2000? The .docs & .tifs we used to store just about tripled in size when we put them in the db in 2000. Plus there were the defrag issues and generally it was an unsatisfying experience.
Does anyone know what the advantages/disadvantages of generating Word .xml files might be? Can they be stored as xml data type in SQL Server? Perhaps this is a better option?
If anyone has the time to digest this, please send opinions.
I am using FileUpload control in ASP.net 2.0 to upload files and store them into SQL server database as an image. I am fine with MS office files, image files and etc. We have Product Center (Proe) engineering software to configure parts and the files generated through this software have PLT extension when I store these files, the file type is Plian/text. I am using Fileupload.PostedFile.Content to get the file type. How can I store PLT, TIF files in SQL server? Please help.
Hello there,I just want to ask if storing data in dbase is much better than storing it in the file system? Because for one, i am currenlty developing my thesis which uploads a blob.doc file to a web server (currently i'm using the localhost of ASP.NET) then retrieves it from the local hostAlso i want to know if im right at this, the localhost of ASP.NET is the same as the one of a natural web server on the net? Because i'm just thinking of uploading and downloading the files from a web server. Although our thesis defense didn't require us to really upload it on the net, we were advised to use a localhost on our PC's. I'll be just using my local server Is it ok to just use a web server for storing files than a database?
Hi, I have a concern about adding a new field to a table with image field - which is huge. Will there be a problem with some databases, where they have a hard time locating data correctly after such a large field? Previously this happened to me, and what was advised to put all the big fields at the end of the table. Thanks.
I am storing xml in an xml datatype field in a table. But when I am generating physical file from the xml field, '&' in the xml field is getting converted into '&' in the physical file. But I want '&' to be intact.

DTS is not properly exporting a database between the servers when a table is containing a image fieldReason it gives as ::Error::Transfer Status: Transferring Data: (Table '[dbo].[Here comes the table name used ]') Data truncation occurred in table [dbo].[Here comes the table name used ], column 1. any workaround or solutions would be more appericated
Hi,Tasks in a MS Project SQL Server database have an image field calledTASK_RTF_NOTES. It contains text in RTF format. We would like to convertthis within a standard SQL statement into plain text.I suspect this is not possible without some sort of bolt-on, or at the veryleast using T-SQL in some way.Any ideas?Thanks,Gareth
