Definitely you are missing something. Post your uploading code. Will try to find out the problem.

Any ideas would be really helpful.

When you are trying to save image on the server then this error causes. I am sure your code looks like this

FileName.PostedFile.SaveAs(FileName.PostedFile.FileName)

You need to Map Server path and save file there. Like this

FileName.PostedFile.SaveAs(Server.MapPath(Path.GetFileName(FileName.PostedFile.FileName)))

This line of code will save image on root folder

please don't forget to vote on the post that helped you.

That's what I was trying to tell him 1. Create one folder (suppose: image) in your portal, 2. save that file using Server.MapPath("\\image\\" + Path.GetFileName (FileName.PostedFile.FileName)) 3. Save that path ("\image\..filename.jpeg") into database 4. Now when u want to access that file, just retrive that path from database (eg. str), and write image.URL = Server.MapPath(str). 5. That's all!!!!!!!!!! right???

Ok Firstly I'll give you all a quick runthrough of what I'm doing. Essentially I'm Identifing the file, loading and resizing it in memory and producing a System.Data.Linq.Binary object that is uploaded to my database. All this works when I'm running the website on my local machine. The live version can't find the file. Here Goes:

'----------------------------------------------------------------------------------
' Name : btnAddPhoto_Click
' Purpose : This event handles the Conversion of the uploaded image files to System Data Linq Binary.
'----------------------------------------------------------------------------------

Protected Sub btnAddPhoto\_Click(ByVal sender As Object, ByVal e As System.EventArgs) 'Handles btnAddPhoto.Click

    Dim photoFileUpload As FileUpload = CType(dvCrops.FindControl("photoFileUpload"), FileUpload)


    If photoFileUpload.PostedFile Is Nothing Then

        lblMessage.Text = "No file specified."

        Exit Sub

    Else

        Dim FileName As String = photoFileUpload.PostedFile.FileName


        Dim ext As String = FileName.Substring(FileName.LastIndexOf("."))

        ext = ext.ToLower


        If ext = ".jpg" Then

        ElseIf ext = ".bmp" Then

        ElseIf ext = ".gif" Then

        ElseIf ext = "jpg" Then

        ElseIf ext = "bmp" Then

        ElseIf ext = "gif" Then

        Else

            lblMessage.Text = "Only gif, bmp, or jpg format files supported."

            Exit Sub

        End If

        ' convert the fileupload.postedfile to system.data.linq.binary
        Dim source As FileInfo = New FileInfo(FileName)
        Dim buffer() As Byte = New Byte(photoFileUpload.PostedFile.ContentLength - 1) {}
        source.OpenRead.Read(buffer, 0, photoFileUpload.PostedFile.ContentLength)


        buffer = ResizeImageFile(buffer, 200)
        crpImage1 = New System.Data.Linq.Binary(buffer)
        lblMessage.Text = "Image Successfully Uploaded."
    End If

End Sub

ResizeImageFile refers to this:

Public Shared Function ResizeImageFile(ByVal imageFile() As Byte, ByVal targetSize As Integer) As Byte()
Using oldImage As System.Drawing.Image = System.Drawing.Image.FromStream(New MemoryStream(imageFile))
Dim newSize As Size = CalculateDimensions(oldImage.Size, targetSize)
Using newImage As Bitmap

This is very wrong way of getting the bytes of uploaded file. What you are trying is, you are getting the filename and trying to get the bytes of invalid file in the server.

Dim FileSize As Integer = 0
FileSize = fileUpload.PostedFile.ContentLength
Dim FileData(FileSize) As Byte
fileUpload.PostedFile.InputStream.Read(buffer, 0, FileSize)

Now you will get the bytes of the selected file.

My fingers were well and truly crossed then. Sadly no luck.

Dim source As FileInfo = New FileInfo(FileName

) I wasn't happy with that part of the code. I'm pretty much a beginner so I'm sure there are a few more bits in there that could do with an overhaul. Could there be a problem with the way the stream is read from my computer from the server e.g should "\" be "/"?? Thanks so far!

As I told you before you are trying to get the bytes of a file from the user's machine in the server's location. Rather, FileUpload control automatically provides the bytes using a simple function call like fileUpload1.PostedFile.InputStream.Read(arg1, arg2, arg3) (refer my previous post for the code).

Ok this is what I have done so far. It's still giving me the same error. Thanks for staying with me so far.

Dim photoFileUpload As FileUpload = CType(dvCrops.FindControl("photoFileUpload"), FileUpload)

Dim myfile As HttpPostedFile = photoFileUpload.PostedFile

Dim FileSize As Integer = 0

FileSize = myfile.ContentLength

Dim FileData(FileSize) As Byte

myfile.InputStream.Read(FileData, 0, FileSize)

FileData = ResizeImageFile(FileData, 200)

crpImage1 = New System.Data.Linq.Binary(FileData)

What am i doing wrong?

That is it. Now it should be all set, I believe.

Thanks for your help. I forgot to upload the new dll file for my site so the changes were not being implemented. Thankyou again
