HOW To Retrieve An Image From Sql Server And Display It In ASP.net Using Imagemap Or Image ?
Jul 6, 2006Ok, the problem is that , i have a field called "Attach" in sql of type image, when selecting it , the field is getting data of type BYTE(). which am being unable to display them on an Image on the panel.
using the following vb.net code:
'Dim sel2 As String
'Dim myCom As SqlCommand
'Dim conn As New SqlConnection
'Dim drr As SqlDataReader
'Dim image As System.Drawing.Image
'sel2 = "select * from attach where att_desc = '" & DropDownList1.SelectedItem().Text & "' and doc_code = " & w_doc_code & " and subcode = " & w_doc_subcode & " and doc_num= " & w_doc_num & " "
'conn.ConnectionString = ("server=developer01;uid=sa;password=aims;database=DVPSOC;timeout=45")
'myCom = New SqlCommand(sel2, conn)
'conn.Open()
'drr = myCom.ExecuteReader()
'If drr.Read Then
' Me.ImageMap1.ImageUrl = drr.Item("attach")
'End If
'conn.Close()
Am getting an exeption on the following line Me.ImageMap1.ImageUrl = drr.Item("attach")
saying: Conversion from type 'Byte()' to type 'String' is not valid.
knowing that i tried converting using ToString but it's not getting any output then.
thanks for your help.

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.

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?

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.

Any idea way is that?
Thanks in advanced.
Display Image Stored In SQL
Sep 9, 2004Hello group
Is there a way to display an image stored in SQL without using a datagrid? I am using vb, the very few examples I do find open the image in a window by its self. Also is there a way find the height and width of an image stored in the database and the ability to change the image size? Example – when an image is uploaded to the database I would like a thumbnail to be created and also stored in the database. Any ideas please help.

Image Does Not Display On Report
Apr 17, 2007I have a simple report that has nothing but an image. The image is part of the project. The image displays in the VS 2005 dev environment when report is previewed. But when deployed and run on the report server website, it does not display. If the report is print previewed or exported to Excel, the image displays. I've set my browser to have the least security as possible but still to no avail (made the website trusted as well). The server is running SQL Server 2005 SP2. My browser is IE7. Can anyone please help? Thanks.

Direct Display Of SQL Image Field
Aug 3, 2004Hi
I have a SQL 2000 table in which pictures are stored as an Image column. I want to display then onto a c# aspx webpage without storing them to disk.
What is the best way to read and display the pictures?
In classic ASP I used to do this:
Response.ContentType = "image/jpeg"
Response.BinaryWrite rs.fields("ThisImage")
but I can't get this to work in c#.

SQL CONNECTION - INSERT - RETRIEVE ID - Rename File - UPLOAD FILE
Sep 15, 2007Hi there,
I have inherited a databse and am building a new website to go wiht it.
There is a file upload page which will upload images to a directory. I need to insert into the database retrieve the id just added then upload the image renaming it in the format locID(QueryString)_ImageID(retrieved from database).jpg
The page has a file upload control and a button.
I am trying to write my code behind so that when the button is clicked it inserts location id into the images table retrieves Image id. Renames the file and uploads it to the images folder.
II think i need to call the routine from another routine for the button click but the signatures are different, where am i going wrong? or for that matter have i been pissing into the wind for the last 4 hours?
CODE BEHIND

View 1 Replies View RelatedAdding File Information To SQL Database On File Upload
Apr 18, 2004Hi there :)
I'm in the final stage of my asp.net project and one of the last things I need to do is add the following file information to my SQL server 2000 database when a file is uploaded:
First of all I have a resource table to which I need to add:
- filename
- file_path
- file_size
(the resource_id has a auto increment value)
so that should hopefully be straight forward when the file is uploaded. The next step is to reference the new resource_id in my module_resource table. My module resource table consists of:
- resource_id (foreign key)
- module_id (foreign key)
So, adding the module_id is easy enough as I can just get the value using Request.QueryString["module_id"]. The bit that I am unsure about is how to insert the new resource_id from the resource table into the module_resource table on file upload. How is this done? Using one table would solve the issue but I want one resource to be available to all modules - many to many relationship.
Any ideas?
Many thanks :)
