Hi
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#.

Thank's

Ok, 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.
I have learned lots of informative thing from your forums. I have little problem regarding “Display image from SQL Server on ASP.NET� I have done it and image display on my page from SQL Server. I have cleared you here I have adopt two different methods which are following for displaying picture.
1.Response.BinaryWrite(rd("picture"))
2.image.Save(Response.OutputStream, ImageFormat.Jpeg)
but in both above methods I have faced little problem when image display on my page all other information can not display and I also want to display picture on my specific location on the page. My second question is can use any web control like “Image1� to display image from SQL Server where my pictures are stored.
Hope you will help me.
Thanks and regards

Hello.

I added an image to my report (drag and drop the image from the solution explorer to my report).
When the report first show I can see the image but after I click once on a column arrow to sort it - The image is replace by a small red X.
I checked to see that the image was uploaded to the same directory as my report.
Any idea way is that?
Thanks in advanced.
Hello 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.

I 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.

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 not sure If I can do this with a lookup, but what I would like todo is perhaps use lookup to retrieve a control date from anunassociated table to control what date is entered in another table.For example :the main table , table 1 has many entries with a field called date_enter which is the date the record was entered.table 2 has a control_dateIf the date entered in table 1 is less than or = to the control date wewant to give the user a error message.I am thinking of using display only field and lookup to set itWould need to have the date value from the control table available tothe active table of table 1 when entering the the date_enter.However as there is no join field between the two tables am not surehow to do it. Was thinking might have to add a key field that wasallways null and in the BEFORE EDITADD EDITUPDATE section set it sothat the key would be nullAm using Informix 5 , Any help would be apprecia

DTS is not properly exporting a database between the servers when a table is containing a image fieldReason it gives as ::Error::Transfer Status: Transferring Data: (Table '[dbo].[Here comes the table name used ]') Data truncation occurred in table [dbo].[Here comes the table name used ], column 1. any workaround or solutions would be more appericated

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

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?
