I'm having a problem reading images from a sql table to a datalist... The end result is a small custom photo gallery, nothing intense. If there is a better way than I'm trying, please let me know. Keep in mind, I'm a Jr. Level Programmer, so I'm not quite as technical as some on asp.net... Thanks for your help in advance:
Presentation Layer:
<asp:DataList id="dlImages" style="Z-INDEX: 101; LEFT: 32px; POSITION: absolute; TOP: 24px" runat="server"
RepeatColumns="3" RepeatDirection="Horizonta
<ItemTemplate>
<%# LoadImage(Container.DataIt
</ItemTemplate>
</asp:DataList>
Code-Behind:
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
dlImages.DataSource = LoadDataList()
dlImages.DataBind()
End Sub
Public Function LoadDataList()
Dim SQLConn As New SqlConnection(Configuratio
Dim SQLCmd As New SqlCommand("GetImages", SQLConn)
SQLCmd.CommandType = CommandType.StoredProcedur
SQLCmd.Parameters.Add(New SqlParameter("@GID", 1))
Dim DA As New SqlDataAdapter(SQLCmd)
Dim DS As New DataSet
DA.Fill(DS)
Return DS
End Function
Public Function LoadImage(ByVal img As Byte()) As System.Drawing.Image
Dim objStream As Stream = File.Open(img(), FileMode.Open)
Dim Buffer(objStream.Length) As Byte
objStream.Read(Buffer, 0, objStream.Length)
objStream.Close()
Response.BinaryWrite(Buffe
End Function
Error:
Number of indices is less than the number of deminsions of the indexed array (underlines the img() tag from the Function LoadImage)
Again, any help would be greatly appreciated... I think I am close, but maybe not?? Thanks again!

The example above that you gave - is for a sqldatareader...
Would you do that code you gave above, in the while statment, before you bind it to a datalist?
I think the problem is me understanding... I don't mind switching from a dataset to a datareader, but I need bind it to a datalist somehow... Thanks!
heres another helpful example:

Well, I know how to display one image.. the problem is, I need to display multiple images in the same datalist.. each image is in it's own sql table record...
so in each datalist column, it will show a new image from a new record in the table...
The end results will be a datalist that looks like this....
img1 img2 img3
img4 img5 etc..
I hope this helps...

try something like this:
While myReader.Read
objWriter.Write(myReader("
bmpFile = New Bitmap(stmFile)
Dim b As Array = stmFile.ToArray()
Response.ContentType = myReader("LG_img_contentty
Response.BinaryWrite(b)
'Dim thisformat = bmpFile.RawFormat
'bmpFile.Save(Response.Out
End While
