View 6 Replies View RelatedUpload Image To SQL Database
Apr 3, 2006I am creating a update, delete, edit form for my web database. The form works in everyway except that when I try to upload the image to the database it does not go into the database. (I know the pros and cons of storing images in a database. In this instance it is what makes the most since. )
I have to admit I have never uploaded anything to my server or database before (other than plain text). I have read through several articles and have a high level of understanding.
I found an example on a website that used the OnInserting/OnUpdating command. But it is not working. I tried to find another similar example so that I could better understand it and try to fix what must be wrong. I can't find a similar example.
I am posting the code I have below. Any help would be most appreciated.

Image Upload Problem Into Database
May 3, 2007Hi guys,I'm currently trying to insert image into my SQL db. I have tried a number of methods that were posted online, and so far with no luck.My current code reads: Dim conn As New Data.SqlClient.SqlConnection() conn.ConnectionString = ConfigurationManager.ConnectionStrings("MainDBConnection").ToString conn.Open() Dim cmd As New Data.SqlClient.SqlCommand("SP_SAVEImage", conn) cmd.CommandType = Data.CommandType.StoredProcedure Dim nUserID As New Data.SqlClient.SqlParameter("@nUserID", Data.SqlDbType.Int) nUserID.Value = "1" Dim nAlbumID As New Data.SqlClient.SqlParameter("@nAlbumID", Data.SqlDbType.Int) nAlbumID.Value = "1" Dim sDescription As New Data.SqlClient.SqlParameter("@sDescription", Data.SqlDbType.VarChar, 50) sDescription.Value = "image1" Dim sImageName As New Data.SqlClient.SqlParameter("@sImageName", Data.SqlDbType.VarChar, 50) sImageName.Value = sImageName Dim sImageType As New Data.SqlClient.SqlParameter("@sImageType", Data.SqlDbType.VarChar, 50) sImageType.Value = fileType Dim sImageData As New Data.SqlClient.SqlParameter("@sImageData", Data.SqlDbType.Image, uploadedFile.Length) sImageData.Value = uploadedFile cmd.Parameters.Add(nUserID) cmd.Parameters.Add(nAlbumID) cmd.Parameters.Add(sDescription) cmd.Parameters.Add(sImageName) cmd.Parameters.Add(sImageType) cmd.Parameters.Add(sImageData) Dim reader1 As Data.SqlClient.SqlDataReader reader1 = cmd.ExecuteReaderRunning through debug, everything runs up until the last line, where an error is caught saying : Failed to convert parameter value from a SqlParameter to a String I reckon it's to do with the input sImageData being input as a byte array - but I can't seem to find a way around it. Any help greatly appreciated!!

How To Upload An Image Into SQL Server 2000 Per T-SQL
Feb 11, 2008Hi,
SQL Server 2008 on its way. 2005 should be standard. But sometimes you have SQL Server 2000.
How can I upload an image into the SQL Server 2000 with an T-SQL Statement?
In SQL Server 2005 I would write something like this:
Code Snippet
INSERT INTO ReportingImages
(Name, Img)
SELECT 'UploadTest',
BulkColumn FROM OPENROWSET(
Bulk 'C:ds9.png', SINGLE_BLOB) AS BLOB
That doesnt work under 2000.
What about uploading to the SQL Server 2000 and an Image-Datatype?
Is it even possible in T-SQL without a Web-Service or C#/VB-written tool?
-------------------------------
Update: Thank you all for your answers. We'll use a tool then.

strFileName = Mid(strLongFilePath, (Len(strLongFilePath) - intFileNameLength) + 2)
Select Case fileupload1.PostedFile.ContentType
Case "image/pjpeg", "image/jpeg" 'Make sure we are getting a valid JPG image

Sql Image Upload And Retrieval?
Apr 9, 2006Hi all, I dont know if anyone here can help me...I am using ASP.NEt with VB.Net and SQL Sever...What I am trying to do is create a system whereby it allows users to upload images into sql server, and thereon later retireve this image.I used a book called The Ultimate VB.Net and ASP.Net Code Book, and it basically gave me the code below to upload and retrieve images. I seem to have managed to allow the uploading of images, with them being stored as <byte> in my database, thought I have no idea how to retrieve them...Does anyone have any ideas???Here is the code I followed.. :"Storing Uploaded Files in Your Database First, a few tips on storing files inside your SQL Server database.For convenience, you’ll really need to store at least three bits of information about your file to get it out in the same shape as you put it in. I’d suggest “data� (a field that will hold your actual file as a byte array, data type “image�), “type� (a field to hold details of the type of file it is, data type “varchar�), and “length� (a field to hold the length in bytes of your file, data type “int�). I’d also recommend “downloadName�, a field to hold the name that the file had when it was uploaded, data type “varchar�. This helps suggest a name should the file be downloaded again via the Web.The problem you have is translating the information from the File Field control into an acceptable format for your database. For a start, you need to get your file into a byte array to store it in an image field. You also need to extract the file type, length, and the download name. Once you have this, set your fields to these values using regular ADO.NET code.So, how do you get this information? It’s simple: just use the following ready-to-run code snippets, passing in your File Field control as an argument. Each function will return just the information you want to feed straight into your database, from a byte array for the image field to a string for the file type.Public Function GetByteArrayFromFileField( _ ByVal FileField As System.Web.UI.HtmlControls.HtmlInputFile) _ As Byte() ' Returns a byte array from the passed ' file field controls file Dim intFileLength As Integer, bytData() As Byte Dim objStream As System.IO.Stream If FileFieldSelected(FileField) Then intFileLength = FileField.PostedFile.ContentLength ReDim bytData(intFileLength) objStream = FileField.PostedFile.InputStream objStream.Read(bytData, 0, intFileLength) Return bytData End If End Function Public Function FileFieldType(ByVal FileField As _ System.Web.UI.HtmlControls.HtmlInputFile) As String ' Returns the type of the posted file If Not FileField.PostedFile Is Nothing Then _ Return FileField.PostedFile.ContentType End Function Public Function FileFieldLength(ByVal FileField As _ System.Web.UI.HtmlControls.HtmlInputFile) As Integer ' Returns the length of the posted file If Not FileField.PostedFile Is Nothing Then _ Return FileField.PostedFile.ContentLength End Function Public Function FileFieldFilename(ByVal FileField As _ System.Web.UI.HtmlControls.HtmlInputFile) As String ' Returns the core filename of the posted file If Not FileField.PostedFile Is Nothing Then _ Return Replace(FileField.PostedFile.FileName, _ StrReverse(Mid(StrReverse(FileField.PostedFile.FileName), _ InStr(1, StrReverse(FileField.PostedFile.FileName), ""))), "") End Function Sorted! One question remains, however. Once you’ve got a file inside a database, how do you serve it back up to a user? First, get the data back out of SQL Server using regular ADO.NET code. After that? Well, here’s a handy function that’ll do all the hard work for you. Simply pass the data from your table fields and hey presto:Public Sub DeliverFile(ByVal Page As System.Web.UI.Page, _ ByVal Data() As Byte, ByVal Type As String, _ ByVal Length As Integer, _ Optional ByVal DownloadFileName As String = "") ' Delivers a file, such as an image or PDF file, ' back through the Response object ' Sample usage from within an ASP.NET page: ' - DeliverFile(Me, bytFile(), strType, intLength, "MyImage.bmp") With Page.Response .Clear() .ContentType = Type If DownloadFileName <> "" Then Page.Response.AddHeader("content-disposition", _ "filename=" & DownloadFileName) End If .OutputStream.Write(Data, 0, Length) .End() End With End Sub Simply pass your byte array, file type, and length, and it’ll send it straight down to your surfer. If it’s an image, it’ll be displayed in the browser window. If it’s a regular file, you’ll be prompted for download.If it’s made available for download, this function also allows you to specify a suggested download file name, a technique that many ASP.NET developers spend weeks trying to figure out. Easy! Working with Uploaded Images Whether you’re building the simplest of photo album Web sites or a fully fledged content management system, the ability to work with uploaded images is a vital one, and with ASP.NET, it’s a real doddle.The following code snippet shows you how, by example. It takes a data stream from the File Field control and converts it into an image object, adding simple error handling should the uploaded file not actually be an image. The code then uses this image object to extract a few core details about the file, from its dimensions to file type:' Get data into image format Dim objStream As System.IO.Stream = _ MyFileField.PostedFile.InputStream Dim objImage As System.Drawing.Image Try ' Get the image stream objImage = System.Drawing.Image.FromStream(objStream) Catch ' This is not an image, exit the method (presuming code is in one!) Exit Sub End Try ' Filename Dim strOriginalFilename As String = MyFileField.PostedFile.FileName ' Type of image Dim strImageType If objImage.RawFormat.Equals(objImage.RawFormat.Gif) Then strImageType = "This is a GIF image" ElseIf objImage.RawFormat.Equals(objImage.RawFormat.Bmp) Then strImageType = "This is a Bitmap image" ElseIf objImage.RawFormat.Equals(objImage.RawFormat.Jpeg) Then strImageType = "This is a JPEG image" ElseIf objImage.RawFormat.Equals(objImage.RawFormat.Icon) Then strImageType = "This is an icon file" ElseIf objImage.RawFormat.Equals(objImage.RawFormat.Tiff) Then strImageType = "This is a TIFF file" Else strImageType = "Other" End If ' Dimensions Dim strDimensions As String strDimensions = "Width in pixels: " & objImage.Width & _ ", Height in pixels: " & objImage.Height ' Send raw output to browser Response.Clear() Response.Write(strOriginalFilename & "<p>" & strImageType & _ "<p>" & strDimensions) Response.End() "For some reason the retrieval code isnt working for me..Can anyone provide any help? even if it means using another method?

Upload SQL Database To Server
Sep 19, 2006Okay, I am still really new at this so nobody laugh if this seems simple stupid. I created a little web page and while working on the project created a new database by right clicking on my app and clicking "Add New item" then choosing SQL Database. I added tables and everything was working just dandy on my machine. I FTP'd the files up to my web server and am now getting an error. SQL is installed on the server, but I have a couple of questions.1. Does SQL have to be installed on the server if you create one of these databases by doing the Add New Item button?2. After Uploading it to a server with SQL installed, the database shows in my App Data folder, but gives me an error. What needs done to move this database to the server besides uploading it?Here is my error:An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)

I've got a simple yet concerning problem. How do I get the MSDE database I've created off my PC and onto the web server? I've thought of doing a "BACKUP DATABASE dbname TO DISK = 'blah,blah'", then upload it and hope I have permissions to execute a DATABASE RESTORE... Any other methods?
Upload Database To Remote Server
May 12, 2006I have a database on my local system and I use Sql Server 2005 express. Now I need to upload the database in the hosting server. I have tried Management Studio Express.
View 1 Replies View RelatedHow Do I Upload To And Download From A Shared SQL Server 2005 Database?
Dec 13, 2006My hosting gives me ASP.NET 2.0 and a shared SQL Server 2005 package.
I have Visual Studio 2005 on my machine - which installs SQL Server 2005 Express. I have also installed SQL Server 2005 Management Studio Express.
I wish to develop my database locally (mdf file) as I won't always have internet access (and therefore can't always work directly with the remote shared database).
My question is, how do I upload my database info from my local machine to my remote shared database?
Also I shall wish to download my remote database to my local machine in order to work on the database (and then be able to re-upload it) sometimes.
Please can somebody tell me how I can do this?
Will SQL Server 2005 Management Studio Express permit me to do this and if so how?
If I need the full version of SQL Server 2005 Management Studio then I do have SQL Server 2005 and this install with it (but it all looks a bit complicated to install for me).
Many thanks for all help given,

View 2 Replies View RelatedSending Uploaded Image To Data Access Class When Storing Image In SQL Server 2005
Apr 20, 2007I 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.
