Hi,
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.
Regards,
JB

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

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 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.

Hi,
I was wondering if someone can help me with is problem.
I have uploaded word docs to the db which is fine. The problem is viewing. I can view then as word documents but the boss does not want the files opened in word.
Is it possable to retrieve the file from from the db and put into say a textbox or lable.
I can see the letter P using this code
Dim Doc() As Byte = New Byte(Convert.ToInt32(0)) {}
Dim bytesReceived As Long = DBContent.GetBytes(0, 0, Doc, 0, Doc.Length)
Dim encoding As ASCIIEncoding = New ASCIIEncoding
lblTest.Text = encoding.GetString(Doc, 0, Convert.ToInt32(bytesReceived)).ToString
Can any help
Thanks
Hi,
does anyone know a way, using native SQL, to store a result of a query in an image field of a certain table.
The case is we have a selfmade replication to communicate with several SQL servers in stores, this replication is over a telephone line. So we collect all the data using SQL statements and store them in a separate table as an image field. This is done know through a Delphi application that streams the resultset to a image field.
Thanks in advance,
I try with textcopy but I did'n do nothing. Please help me

View 2 Replies View RelatedI am creating a document management systems using asp. I have beenresearching the different ways of handling the documents such as using thefile system and storing the path in the db, and actually storing thedocument in the db. I like the idea of storing it in the database muchbetter because I can allow users to manage documents themselves (I alreadyhave the code in place to do it if I decide), having a central system withthe ability to add my own document properties by adding fields to the table,security, and backups. I have found that most think it is better to storethe path due to performance issues and the rate the db can grow. I havelooked at our current system in access and we have a total of 4400 documents(of which probably 25% are in the database but don't actually exist anymorein the file system, one hangup about the file system) since 1988. Thiscomes to about 300 documents added each year. The other thing is the issuewith the size of the db. I don't see a whole lot of difference with thisissue because it is going to take up space in your file system too, althoughthe file system may be more efficient at storing them. I would say that 95%of our docs are under 1 mb in size and done in ms word.The last thing is using full-text search capabilities in SQL Server. I needto be able to search the contents of the field.Is there other issues around storing documents in the db to consider besidesthe above?

Hi everyone.
I have a field that is image datatype. That table is included in a snapshot replication. When I try to update that field - on the publication server, which is the same as distributor server - if the image is too big (in size), an error message appears. When I try to update with images that has less size it works. If I take out the subscriptions, it works for every image size.
Any ideas?
hi can anyone tell how to use the image field and add an image in a database. i'm using visual studio web developer express edition 2008 and i want people who visit my website to be able to see the table and the images associated with some of the rows in the table

I want to be able to load and unload, byte-for-byte, a file to and from a field of data type IMAGE in a SQL Server CE database. The files are larger than 8000 bytes so IMAGE appears to be the way to go data type wise.
I'm using VB 2008 but pseudocode for any VS language would be awesome.
I was able to do this without much effort using ADODB and its stream object, fetching a recordset object and updating the appropriate data field one "chunk" of bytes at a time. I cannot for the life of me find a way of doing this using, for example, a SqlCeResultSet.
I've tried using ADODB to connect to a SqlCe SDF database file, using a connection string that I found online, and am able to write action and select queries successfully against the database... but when I try and return a recordset that is updatable, it returns an error. So no help there.
I've searched other threads in the forums, and online in general, and I've found information on loading/unloading graphic files using a memoryStream and the toArray method thereof, but this will not work as many of the files I want to load and unload as BLOBs are not graphical in nature. FileStreams do not implement the toArray method, so I can't just stream an arbitrary file's worth of bytes that way. I also do not want to change the original file in any fashion--e.g., a hash of the source file should be identical to the file after it has been loaded into the data field and then unloaded into a new file.
Any thoughts? Your help is MUCH appreciated!
I have to access a web service where I pass in a product number and it produces an XML result with an /image section where it has a long string (base64?) I am trying to call the web service and save the image to the OS.

The ERP manufacturer used an image data type to store large text data fields. I am trying to move these data types from one database to another database using either Sql Queries or MS Access. I can cast them as an 8000 char varchar to read them directly but have no luck importing into these image data fields.
Access and Crystal are not able to read these fields directly.
Any suggestions? Most information about these fields has to do with loading files but I am just moving data.
Thanks,
