View 3 RepliesIn of my application I am using the database to store and retrive images. The table stores the documents and the datatype of the field is IMage.
Now with Sql Server 2008, i would like to upgrade this to use this new feature. WHat changes do I have to make in terms of code and also in the database.
I've got a vb.net page that when a user clicks a button in a gridview, it copys the file (row seleted) in the gridview as "Label2" from the webserver to the users pc. (We had to setup a lot of security to get it so the webserver could copy to the users pc). I have that all working fine, but now, I'm trying to see if FileStream will then open the file that was just downloaded on the users PC. I'm not familiar with FileStream, and could use a little push in the right direction. (Disclaimer, yes I know downloading the file directly to the pc is a crazy thing to do, but it's a really long story. :-)
For the FileStream portion, I found this sample, but don't quite understand if I can incorporate it into my button click event. Here's the sample [URL]

View 6 RepliesI'm using Cute Editor for ASP.NET for the first time, and it's occasionally refusing to insert or update a record. Basically the records are just composed of a bunch of HTML and text. So far I can't detect a pattern to the problem and I'm wondering about my data type.
I tried VARCHAR(MAX), NVARCHAR(MAX), and NTEXT, doesn't seem to fix it.
So what is the best SQL data type for HTML?
And could that be causing CuteEditor to refuse to insert/update records? Or something else?

i need to save multiple documents stored in SQL server as Image type to disk.
What i want to do is "backup" all files in a table (column) to disk, zip them and Response.TransmitFile(FilePath) to client.
I could use C# ot VB but that would require a lot of connections to database or a lot of server memory and i don't want that, becauze there are a lot of files to be saved Since SQL can write files to disk i was thinking about saving those files to disk directly from sql. Something like when u're doing a backup
