Uploading Image To Database
Nov 4, 2006
I'm trying to upload an image to a database along with some other info. I have a form to get all the info from the user that I want to put in the database. Everything's getting into the database except for the actual image data. When I do a "select * from table" query on the database, the Image field reads "err", however I have an imagetype field in the db and it reads "image/jpeg". I have the following code to get the image into the database:

I have a directory of files that I would like to upload with some datato a table so that I can store the files in the db. I'm not trying toparse files into rows, I want to stick the actual file in the column.Is there some kind of insert script, or bulk copy that I can use?I have about 150 docs and I would rather not go through the whole app,pick the file, upload it. etc.thx,M@

hi,my sql database works fine from my desktophowever when uploading it to my web server it does not work.i considered this could be the connection path to the database.in visual web developer i attempted to modify the connection for the actual web address on the server pc like this:C:Inetpubvhostsarcvillage.comhttpdocsApp_Datavillagers.mdf this is the actual path on the server.However visual web developer will not allow this because it says that this connection is not available ON MY PC.... so i cant save this new connection in order to upload it.any suggestions please.... or am i barking up the wrong tree!

I was following an example from the book "ASP.net unleashed" in Chapter 14, where it describes how to upload a file directly into the database.
I got it to insert the file into my database as described, and with changes created a master and detail form to select the file and display it.. (which I assume had worked).
Except, when attempting to access the file it gives two different errors. For a ppt file it gives:
The XML page cannot be displayed
Cannot view XML input using style sheet. Please correct the error and then click the Refresh button, or try again later.
An invalid character was found in text content. Error processing resource 'http://localhost:3870/SeminarOrganiser/view_file...
and for a simple txt file:
The XML page cannot be displayed
Cannot view XML input using style sheet. Please correct the error and then click the Refresh button, or try again later.
Invalid at the top level of the document. Error processing resource 'http://localhost:3870/SeminarOrganiser/view_file.aspx?...SELECT suggestEvent.suggestID, suggestEvent.uID, users.uFirstName, users.uLastName, users.uEmail, suggestEvent.suggestTitle,...From these two errors, I cannot really make sense of what has gone wrong or even why XML has even been mentioned. Looking around on the net has not allowed me any further progress.In any case, would anyone be able to explain to me what might have gone wrong?Alternatively, any links that may help would be greatly appreciated.Thank you very much in advance.

hi,
From my ealier post I learned that a MDF file can be read and written to even if I did not attach the database in the SQL Sever Management Studio.
Is that behavior because of the connection string where is has
AttachDBFilename=|DataDirectory|DNN12_24_07.mdf ,
Is that what "attaches" the database? This runs on SQL Express2005.
Should I change the connection string to:
name="SiteSqlServer" connectionString="Server=(local);Database=ASPNET;uid=;pwd=;" providerName="System.Data.SqlClient" />
?
Is there a statment in the XML of web.config that defines |DataDirectory| of the original connection string that points to APP_DATA where the mdf file physically resides?
Thanks in advance?

hello,
After I FTP a ASP.NET website to a webserver, APP_DATA directory and all, I then use the SQL publishing wizard to create a script on the local machine and run the script on the webserver/SQL server, it builds ok. But I get an error "another database with the same name". Duplicate of the database in APP_DATA directory that is already attached by the connection string. So this isn't correct.
Second attempt: I FTP an ASP.NET website up to a server. Then I open the SQL management studio and attach the database in the website's APP_DATA folder. (never running a .sql script)The database attaches. The name of the database is the complete path to the database in the APP_DATA directory by default. The website functions. But if I try to look at a table I get an errors. It gets to the point the database will not even expand. Then I start getting errors in the browser that NETWORK SERVICE can not open it's default database. So the website fails also. So this doesn't work either....
So I guess my question is, should I remapped the path of |DataDirectory| before I FTP it? To a path where the other common system databases reside, (I don't think that would be necessary.) Then FTP the website without the contents of the app folder(no database). Then use the script built with the SQL Publishing wizard to build the database, and attach the database in SQL Management Studio? ( I'm afraid of over playing and corrupting the server).
If I attach the database to manage it and the connection string attaches the database to run it, will I always get errors? What am I missing here?
Thanks jamesqua for your help so far, I understood the blog you sent me too. But how do I modify it so I can use SQL Management studio to manage the database?

This is probably a very simple question but i am having problems with inserting information into database
The function takes the values "FirstName" And "LastName" from A table Called "Customer" and the value "ProductID" from a table called "Products" and inserts them into a table called " NewOrder".
Everything compiles ok but when I press the button the information is not uploaded to thedatabase. ( There is no error message)
This is the stored procedure
CREATE PROCEDURE SP_NewOrder(@CartID char (36), @CustomerID Varchar (50))AS
INSERT INTO NewOrder (FirstName, LastName, ProductID)
SELECT Customer.FirstName, Customer.LastName, Products.ProductID
From Customer,Products Join ShoppingCart ON Products.ProductID =ShoppingCart.ProductIDWHERE ShoppingCart.CartID = @CartID AND Customer.CustomerID = @CustomerIDGO
This is the Function
Public Shared Function CreateOrder() AS String Dim customerID As integer Dim connection as New SqlConnection(connectionString) Dim command as New SqlCommand("SP_NewOrder",connection) command.CommandType = CommandType.StoredProcedure command.Parameters.Add("@CartID", SqlDbType.Char,36) command.Parameters("@CartID").Value = shoppingCartID command.Parameters.Add("@CustomerID", SqlDbType.Varchar,36) command.Parameters("@CustomerID").Value = customerID Try
connection.Open() command.ExecuteNonQuery() Finally connection.Close()
End TryEnd Function
This is the page code
Sub btn3_Click(sender As Object, e As EventArgs)Dim cart as New ShoppingCart()Dim shoppingCartID As IntegerDim customerID As Integer = Context.Session("worldshop_CustomerID")cart.CreateOrder()End Sub
Can Anyone see where I am going wrong
Many thanks

Does anyone know how to upload (bulk) data from a client (written in Excel VBA) to a remote SQL2000 database? Of coarse I tried "INSERT INTO" and rst.addnew but I noticed this is much, much slower as downloading from the same remote database.

Hi, I'm developing a website using VWD 2005 Express, which needs a Membership system and a products database. Using the VWD inherent Web Site Administration tool makes the membership set up easy but by default it creates a 'Local' SQL database in a folder named 'Apps_Data' in the VWD project. My question is: considering I will need to upload my web site to a Hosting Service, would it be better to change the default so that the membership systems, and the product database I need, are created in an SQL 'Server' database instead of a 'Local' database?
The hosting service I am considering using is having a bit of a problem understanding this question, I hope it makes sense to someone or am I asking a stupid question?
Regards
Sean.

Hello,
I would like some help in uploading a database from my harddrive to a server using sql server management studio express.
If I try to attach it to the server, this program only looks at the files on this server and not on my harddrive. So how can I copy a sql database to my folder on the server.
I am sure it must be a simple problem, but I've been bizzy with it for about a day now. So, please advice.
Rgds,

Hi,
I needed to recreate/publish a DDL and data file(of a database) that was produced using Database Publishing Wizard. The size of the file is 4G. I receive the following error when I try to open it up in the new query window of sql server 2005 (sp2)for execution.
"The operation could not be completed. Not enough storage is available to complete this operation."
I know my server has 829G of free storage space available. i receive no errors when I open up a smaller file also created by database publishing wizard.
What possibly is causing this?
Thanks in advance

I am new with Visual Web Developer SQL Express and for a start I have been using the VWDHosting.net (Trial hosting for VWD 2005 Express) with a test website using login and membership controls. I followed the excellent instruction in the User Guide (for transferring data and adapting the connectionstring) and it worked succesfully. However, I have problems getting the same test website installed with my hosting provider.The VWDhosting.net has a special functionality for uploading the contents of a local database to a database created on the server. In the Restore database section is a field the "Restore database from SQL Server 2005 mdf file". After selecting in that field your local database, you can click the "Attach"-button and then the contents of the local database are transferred to the database on the server. With my hosting provider (using SQL Server 2000) I have to use the same procedure: creating a MS SQL database on the server and then transfer the contents of my local database. How can I do this? (My hosting provider does not offer me a similar "Attach" button).Do I have to use SQL Server Management Studio?Kees

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 want to store an image hyperlink in a sql database but don't seem to be able to do it..is this do-able?
I can store a hyperlink in text format, no problem, but how do I do the same with an image?
I want to use images in my images folder. I can create an image field and set the required options to display images all that is pretty straight forward but trying to display the image as a hyperlink ( actually it's a mailto: link I want to use) seems not to be an option.
The purpose of this is to allow users to upload an image together with their email address and when other users click on the image it fires up their email app. I do not want to have to use a text link.
Thanks

Ok, again, I'm reasonably new to this. I've been trying to display an image stored in SQL in a ASP.NET page. Pretty simple stuff I would have thought. I've read countless examples of how to do this online, and many of them use the same method of displaying the image, but none seem to work for me. The problem seems to lie in the following line of code:
Dim imageData As Byte() = CByte(command.ExecuteScalar())Which always returns the error: Value of type 'Byte' cannot be converted to '1-dimensional array of Byte'.Here's the rest of my code, hope someone can help. It's doing my head in!
Imports System.Data.SqlClient
Imports System.Data
Imports System.Drawing
Imports System.IOPartial Class _ProfileEditor
Inherits System.Web.UI.PageProtected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
'Get the UserID of the currently logged on user Dim NTUserID As String = HttpContext.Current.User.Identity.Name.ToString
Session("UserID") = NTUserID
Dim Photo As Image = NothingDim connection As New SqlConnection(ConfigurationManager.ConnectionStrings("MyConnectionString").ConnectionString)
Dim command As SqlCommand = connection.CreateCommand()
command.CommandText = "SELECT Photograph, ImageType FROM Users WHERE UserID = @UserID"command.Parameters.AddWithValue("@UserID", NTUserID)
connection.Open()Dim imageData As Byte() = CByte(command.ExecuteScalar())Dim memStream As New MemoryStream(Buffer)
Photo = Image.FromStream(memStream)
End Sub

Dear Friends,
I have read many solution over the net, but since I am unable to utilize anyone according to my needs I am seeking help from you people.
I have a table imagedata in sql server 2005 having fields name and imageperson. Name is string and imageperson is Image field. I have successfully stored name of the person and his image in database.
I have populated the dataset from codebehind and bind it to the repeater.
By writing <%# DataBinder.Eval(Container.DataItem, "name")%>I am a able to retrieve the name of the person. But when I pass photodata as
<%#photogen((DataBinder.Eval(Container.DataItem, "imageperson")))%>
where photogen is function in code behind having structure
public void photogen(byte[] dataretrieved)
{
Response.BinaryWrite(datarerieved)
}
But it is giving error at <%#photogen((DataBinder.Eval(Container.DataItem, "imageperson")))%>
The best overloaded method match for '_Default.photogen(byte[])' has some invalid arguments
AND
Cannot convert object to byte[].
Can anyone please provide me working solution with code for aspx page and code behind.
Thanks and regards
