Please help with uploading a file to server

Posted By:      Posted Date: October 12, 2010    Points: 0   Category :ASP.Net

I am using VB to upload image files to my server but am having problems. How can I use the ContentType to filter only image files? This is my code for my upload button which does not seem to be working. I can only upload bmp files:

Protected Sub btnSave_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSave.Click
        If txtFileUpload.PostedFile.ContentLength = 0 Then
            lblMessage.Text = "No file to upload"

            'if the upload does not contain an image...error
            If txtSaveAs.Text Is Nothing OrElse txtSaveAs.Text.Trim() = "" Then
                txtSaveAs.Text = txtFileUpload.FileName
                txtSaveAs.Text = txtSaveAs.Text.Trim()
            End If

                Dim path As String = Server.MapPath("~/images")
                Dim fileType As String = txtFileUpload.PostedFile.ContentType

                If fileType = "image/bmp" Or fileType = "image/jpg" Then
                    txtFileUpload.PostedFile.SaveAs(path & "\" & txtSaveAs.Text)
                    lblMessage.Text = "file sucessfully uploaded to: "
                    lblPath.Text = path & "/" & txtSaveAs.Text

                    hlImageView.Visible =

scripts file not found on server - 404


Fiddler is showing a 404 error when my published web application runs. the jquery.js file in
/scripts is highlighted in red by fiddler as not found. ( IIS log also shows the 404 error ).
I run the web app from visual studio, on local host - no problems. The publish is successful.
All the files are in the scripts folder of the web app on the server.

In the site.master I have:
<script src="../../Scripts/jquery-1.4.1.min.js" type="text/javascript"></script>

Visual studio does not complain about this. ( which indicates the file is found. )

Oddly, when I fully qualify the path, VS says file not found, but after I publish and run, fiddler
shows the jquery file being found and sent to the browser.
<script src="/MvcApplication1/Scripts/jquery-1.4.1.min.js" type="text/javascript"></script>

when the <script> path is "../../Scripts/jquery-1.4.1.min.js", the fiddler error is
404: /Scripts/jquery-1.4.1.min.js .

when the <script> path is "/MvcApplication1/Scripts/jquery-1.4.1.min.js", fiddler shows the file
being sent to the browser from that /MvcApplication1/Scripts path.
