I would think you would have to use an html file upload input control. (You cannot create common dialog boxs on a web app). You should be able to grab the selected filename from it???
<INPUT id="File1" type="file" name="fileInput" runat="server">
pseduo code to upload a file, modify accordingly:
If Not File1.PostedFile Is Nothing AndAlso Not File1.PostedFile.FileName = String.Empty Then
Try
fileName = Server.MapPath("~\uploads\") & Path.GetFileName(File1.PostedFile.FileName.ToStrin g)
File1.PostedFile.SaveAs(fileName)
fileSize = CType(File1.PostedFile.InputStream.Length, Integer)
contentType = File1.PostedFile.ContentType()
Dim fs As FileStream = New FileStream(fileName, FileMode.Open, FileAccess.Read)
imagefile = New Byte(CType(fs.Length, Integer)) {}
fs.Read(imagefile, 0, CType(fs.Length, Integer))
fs.Close()
FileFound = True
Catch ex As System.IO.FileNotFoundException
Trace.Warn("file not found", ex.ToString)
Catch ex As Exception
Trace.Warn("upload", ex.ToString)
End Try
End If

Hi All,
Can anyone help me out with this one. I have a basic aspx page with an image placeholder on it. I want to be able to click a button on the page and have a dialog window appear where I can navigate the Client's PC and select a file (a JPG of GIF). I then want to change the image placeholder to display the selected image.
The problem I have is that I just can't work out how to browse the clients hard-disk. I have tried "
commonDialog1 = CreateObject("UserAccounts.CommonDialog")" and
"MyFolder = New System.Windows.Forms.FolderBrowserDialog"
but both give me a dialog window 'ghost' that is, the appear as a frame without any contents. The only way I know they are there is if I drag another application window over them. The screen tries to redraw them without any luck.
TIA,
Peter Wallington
