Sending 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.

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 & " "

'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.

Is it a known restriction? Is it a restriction from ADO.NET or from the database server?
Is it documented somewhere?

Can Not Update A Replicated Image Datatype Field
Nov 30, 2007Hi everyone.
I have a field that is image datatype. That table is included in a snapshot replication. When I try to update that field - on the publication server, which is the same as distributor server - if the image is too big (in size), an error message appears. When I try to update with images that has less size it works. If I take out the subscriptions, it works for every image size.
Any ideas?

Jan 30, 2007In my asp.net application I have a local report with an image control in thedetail row of the table and the Value attribute set as="File://" & Fields!FQPhotoFileName.ValueThe first row in the table always shows the wrong image and it's always thesame wrong image. The problem is there even when I change the sort order orthe criteria for the underlying dataset. For example, I ran a small testthat populated the dataset with 2 rows and 2 images. When I sort by anycolumn (e.g. ID) in ascending ascending order the ID=1 row (the 1st row)shows the wrong image and the ID=2 row shows the correct image. When I rerunthe report sorting in descending order the ID=2 row (which is now the 1strow) shows the wrong image and the ID=1 shows the correct image.Any suggestions?

Inserting Image Data Type From SQL Server CE To SQL Server 2000.
Oct 23, 2006Hi All,
I am manually replicating parts of a SQL Server CE database (running windows mobile 5.0) to a centralized SQL Server 2000 database.
My program is throwing an exception whenever I try to insert an image data type into the 2000 server from the PDA. I am using parameterized queries.
Error is as follows:
[error]
System.Data.SqlClient.SqlConnection.OnError()
at
System.Data.SqlClient.SqlInternalConnection.OnError()
at
System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning()
at
System.Data.SqlClient.TdsParser.Run()
at
System.Data.SqlClient.ExecuteReader()
at
System.Data.SqlClient.ExecuteNonQuery()
at
PDASync.Database.ExecuteIDRemote()
[/error]
The code for my ExecuteIDRemote method works fine for other queries. It also works if I remove the image column from the offending query.
Does anyone have any suggestions? Thanks.

Image Problem In Sql Server & Asp.net
Sep 8, 2007Hi friends,
I am using ASP.NET (with C#) and SQL Server 2005 Express Edition.
I have to store images in database.
When I download the image from SQL, it gives exception 'Parameter is not valid.'
I check the size of the byte array and it is really not valid.
I store an image that has a size of 4991 bytes(as a byte array). But when I download it, it has only 13 bytes(byte array again).
This is my upload code :
MemoryStream ms = new MemoryStream();
System.Drawing.Image im = System.Drawing.Image.FromFile(Server.MapPath("Image\example.gif"));
Byte[] byteArray;
im.Save(ms, ImageFormat.Gif);
byteArray = ms.ToArray();
Here ms.Length is 4983 bytes not 4991! example.gif is 4991 bytes.
My SQL sentence :
"update reklamlar set Resim=" + byteArray + " where ReklamID=1;"
My download code :
byteArray = new byte[reader.GetBytes(4,0,null,0,int.MaxValue)];
mstream.Write(byteArray, 0, byteArray.Length);
System.Drawing.Image im = System.Drawing.Image.FromStream(mstream);
Here byteArray.Lenght is only 13!!!
Please help me what is wrong with this code?
Thanks a lot..
Note : In SQL management studio express, in the image area this text is written : <binary data>
It is 13 characters you see. May be there a relationship???
