I am having conflicting results with two pieces of identical code. One
is an insert, the other is an update to a db.
The first code, which works, is this:
Sub Add3_Click(sender As Object, e As EventArgs)
Dim imgStream as Stream = Add3Image.PostedFile.InputStream
Dim imgLen as Integer = Add3Image.PostedFile.ContentLength
Dim imgType as String = Add3Image.PostedFile.ContentType
If Not imgStream Is Nothing And imgLen > 0 And (imgType =
"image/jpeg" Or imgType = "image/pjpeg") Then
Dim imgBin() as Byte
imgBin = createThumbnail(imgStream, 200, 200)
Dim myConn as New
OleDbConnection(ConfigurationSettings.AppSettings( "strConn"))
Dim myCmd as New OleDbCommand("INSERT INTO tblNews ([Date], [Name],
[Image], [Comment]) VALUES (@Date, @Name, @Image, @Comment)", myConn)
myConn.Open()
myCmd.CommandType = CommandType.Text
myCmd.Parameters.Add("@Date", OleDbType.Date).Value =
request.form("Add3Date")
myCmd.Parameters.Add("@Name", OleDbType.VarWChar).Value =
RepChar(request.form("Add3Title"))
myCmd.Parameters.Add("@Image", OleDbType.LongVarBinary).Value = imgBin
myCmd.Parameters.Add("@Comment", OleDbType.LongVarWChar).Value =
RepChar(request.form("Add3Comment"))
myCmd.ExecuteNonQuery()
myConn.Close()
Else
Dim myConn as New
OleDbConnection(ConfigurationSettings.AppSettings( "strConn"))

The first one works, but the second one doesn't seem to work no matter
WHAT I try to do. As you can see, the code is nearly identical (with the
major exception of the SQL statements).
One major problem with the second one is an "Edit3Image is not defined"
error, even though it exists in the form. When I checked out the form,
however (view source in my browser), I saw that all of the ID tags had
changed dramatically - to the value plus a nonsensical string. Not only
did that ensure that "Edit3Image" couldn't be found, but that also
prevented the JavaScript (a popup calendar) from allowing the date to be
changed in "Edit3Date". How do I make both the JS and the form work
together???
BTW, the second is inside a repeater because I *need* it to be filled
with content from the database. It is the update/delete page, whereas
the first one was the add page.

(a) too much code, it hurts my eyes
(b) don't use bad language!
(c) I believe the problem to be simple
Edit3Image is defined in a repeater. As such you cannot simply refer to it
as Edit3Image as there are multiple versions (one for each "row" of data
bound to the repeater). How does .NET know which Edit3Image you want to
manipulate/access? If you want it to work in your javascript, you need to do
something like inputField : '<%# Edit3Date.ClientId %>' which I think will
work.
To make it work in your button click, as there are multiple rows, you'll
need to figure out which Edit3Image you want. If you want each one, you need
to loop through the items of the Repeater, if you want a specific one, you
need to jump to that index:
dim Edit3Date as HtmlInput =
ctype(myRepeater.Items[1].FindControl("Edit3Date"), HtmlInput)
