Here is my task I am storing pdf's in sql server. I would like to retrieve the binary data from sql server and write the pdf content into an existing aspx page to the appropriate pageview section. What is the best way to handle this. The code works below but it loads a new browser with the content. I need it to appear in it's tabbed section in the original aspx file. Any assistance you can give me would be greatly appreciated.
Thanks Jerry

Hi Guys,
I've been strugling with this problem all morning today.
Basically I store images in SQL Server 2000 database and then whould like to show them with
<img src="viewImage.aspx?image_id=10" border=1>
My table structure is setup this way
TABLE [userImages] (
[imageFilename] [nvarchar] (128) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
[imageContentType] [nvarchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
[imageFileSize] [bigint] NULL ,
[imageFileImage] [image] NULL )
and in viewImage.aspx I have:
if (dr.Read())
{
Response.ContentType = dr.GetString(dr.GetOrdinal("imageContentType"));
Response.BinaryWrite( (byte[]) dr["imageFileImage"] );
}
I have no prolems retrieving the data from DB. But the image does not display(in IE it shows a broken link image)
What's even more puzzling is I CAN display the same image from HDD like so:
FileStream fs = File.OpenRead("D:\my_image.png");
byte[] buffer = new byte[fs.Length];
fs.Read(buffer, 0, buffer.Length);
fs.Close();
Response.ContentType = "application/octet-stream";
Response.BinaryWrite(buffer);
Am I missing something very obvious. I tried playing around with different ContentType's same result.
In my case I am forced to store images in the DB.
I've seen other examples on the net and theirs work. Please help.
Sincerely,
Vlad Orlovsky
I was wondering if it is possible to read image data from a database in .net compact framework. Since cf does not have image.fromstream(memstream) to work with, I don't know how else to read the image from the database and then place it into a picturebox.
Here is the code I have been trying out:
Dim Img As Image
'
Dim conn As New SqlCeConnection("Data Source = My Documents est2.sdf")
conn.Open()
Dim sql As String = "SELECT * FROM Dater"
Dim cmd As New SqlCeCommand(sql, conn)
Dim reader As SqlCeDataReader = _
cmd.ExecuteReader(System.Data.CommandBehavior.CloseConnection)
While reader.Read()
TextBox1.Text = reader.Item("name")
Dim b(reader.GetBytes(1, 0, Nothing, 0, Integer.MaxValue) - 1) As Byte
reader.GetBytes(1, 0, b, 0, b.Length)
Dim ms As New System.IO.MemoryStream(b)
Dim bmp As New Bitmap(ms) <-Error: Value does not fall within expected range
Img = bmp
End While
PictureBox2.Image = Img
I get an error ,Value does not fall within expected range.
Does this mean the image was not save correctly in the database?
Thanks for any help
This just happened today and I dont know why. I have a database on a SQL server 2005 database, that has a table called photos. It contains image data, but not the column says <Unable to read data>. But before that I get an error when I try to execute the table to retreive the data. The error is below. SQL Execution Error:Executed SQL statement: SELECT ID, AlbumID, Caption, BytesOriginal, BytesFull, BytesThumb FROM PhotosError Source: System.DataError Message: Invalid attempt to Read when reader is closed. This happens with SQL Server Management Studio, and Visual Studio 2005 when I try to access it. I tried two computers so its not that. Any help or insight would be appreciated.
View 2 Replies View RelatedI have been asked to write a piece of code that will insert an image object into a database using a stored procedure and the Microsoft Enterprise Library. Has anyone done this before? Do you have any code examples about how to update a database with an image datatype that needs to be chunked, etc...
In this instance, I need to open up a word document and save the contents as an image in a database.
hi, i'm a student doing my final year project. during the user requirements stage, my client proposed storing all files (.doc, .jpg, .mp3) into the sql database. i found out that the way to do this is to write the files as binary data in order to store them in the database. my concern is will this data storage overload the database server? i read somewhere that the retrieval of data as binary data is the same as retrieving text. but the estimation of users is around 27,000.. if i'm not wrong, the sql database server should be MS SQL Server 2005, or at least 2003.

The ERP manufacturer used an image data type to store large text data fields. I am trying to move these data types from one database to another database using either Sql Queries or MS Access. I can cast them as an 8000 char varchar to read them directly but have no luck importing into these image data fields.
Access and Crystal are not able to read these fields directly.
Any suggestions? Most information about these fields has to do with loading files but I am just moving data.
Thanks,

It is supposed to be able to store up to 2Gb!!! but when I declare the data field image I can't specify the max size for the field and by default is 16 !!
16 bytes!! what can I do with that?
How can I insert a file?

Hi all,
I am working on application maintance. I got a Contains(myField, myString) that used to look into an image data type field (text) for the string, but right now it's not responding they way it's supposed to do.
Recently really big files have been introduced in the DB, could this related to the issue?
Anyone can help regarding this?
Many thanks,

I'm using ODBC to interface a Microsoft SQL Server 2000. One of theoperations involves placing files within BLOBs. I'm using the imagedata type for this purpose. Most of the time this works okey, but whentrying to add a 21,3 MB file I get an error. The error code is 22001,which means "String right-truncation". But why? Does this mean thatthe field cannot accepts BLOBs with this size?

Hi all,
I have a column in SQL server which is of type ntext. Selecting the specific column to view it in report builder, an error message appears with the following description:
- Cannot run this report. The grouping expression 'nameofcolumn' returns the datatype binary. The Grouping Expression cannot return binary data.
Report Builder recognises this as if it was an image...
Thanks in advance!

I am currently working on an application that uses a stored procedure to retrieve data from a database and then display it in a web page. My problem is that some of the data in the database will be images, I am currently putting in test data to test my code/procedures my problem is how do I put in test data for images, when I am finished I am going to add an admin section that will allow me to add images that way but how do I go about adding them to the database until then? I have set the field to the image data type but have no idea how to relate this to an image on my server?
Thanks, Adam
Hey all,
Just starting to investigate this. I need to store digital pictures in my database for use in claims and disputes. I have played a bit with the image datatype but notice that one picture takes up 1Mb as a TIFF and 3Mb as a JPEG. Does anybody work with this stuff and if you do what is the best picture format to use in regards to keeping clarity but minimizing size used in the db. Is there any load conversion routines that would shrink the size of the file.
Any suggestions or comments on this topic are appreciated.
Thx. Kelsey

Hello, I am trying to store pictures in an Image data type column of my MsSQL table from PHP, or even SQL Query Analyzer for that matter. In PHP I use the bin2hex() function to get the HEX equivilent of the picture, I'm sure everyone knows that when you convert a Binary file to HEX, the file size is doubled. When I try to insert the HEX file into my table with a query like:
INSERT INTO PicTable (fileType, fileData) VALUES ('jpg', 0x47494638396164014100f70000000000ffffff2f2f2fe800020c0c0ce....)
MsSQL will store EXACTLY HALF of the file. The byte count of the stored HEX data and original Binary data is exactly the same, so when I try to extract the file and display it, in a browser window for instance, I can see exactly half of the image. I have tried everything I can think of to fix this, but I am at a loss. Does anyone know of anything that would cause this strange behavior. I have no problems at all doing this with MySQL's BLOB data type. Thanks in advance for any help.
Hi,
I've a column col1 of image data type in table1. I would like to copy the data from col1 to another image column col2 in table2. Before moving the value, checking has to be done to specify which col1 data from table1 is needed and the destination has to be checked too.
Example: insert into col2
(select col1 from table1 where table1_id =5)
where table2_id =6
Hence bcp wouldn't work. Can anyone suggest me a way to do it. I tried using writetext but then, i've to get data from col1 in a variable, which is not possible. Any suggestions would be very helpful.
Thanks in advance.
