Hi

I'm trying to use SoftArtisans.FileUp to upload a text file to the server.  I've used similar code for ASP, but am getting the following error using ASP.NET.  I'm new to this and do not understand the error.  Can someone shed some light?  

The source error points to this line of code...

Line 22: objUpload.Form("file").Save()

The error I'm getting is

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Runtime.InteropServices.COMException: The server threw an exception.


Stack Trace:

put a try/catch block around it and catch the exception that is being thrown.

Try
   objUpload.Form("file").Save()
Catch e As Exception
   Response.Write(e.ToString())
End Try

why not just use regular asp.net upload?

Interesting point AerosSaga.  I read a little about asp.net upload and just might have to give that a try.

I've spent a little time on this current problem and feel like I just need to get to the bottom of it because its driving me nuts.    trevorhartman, thanks for the try/catch block.  here's what I got:

System.Runtime.InteropServices.COMException (0x80010105): The server threw an exception. at Microsoft.VisualBasic.CompilerServices.LateBinding.LateGet(Object o, Type objType, String name, Object[] args, String[] paramnames, Boolean[] CopyBack) at ASP.process_aspx.Local_Page_Load() in C:\Inetpub\wwwroot\test.trends.fusionmedia.com\process.aspx:line 24

Any sense?

just drag the ASP.NET file browser control onto the page and modify this Sub to do what you need it to, save yourself a lot of trouble. I denoted the file saving processes with *****'s

 Private Sub AddProduct_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles AddProduct.Click
        If Not Page.IsPostBack Then Return

        ProductNameValidator.Enabled = True
        Tier1Validator.Enabled = True
        QueryValidator.Enabled = False
        Validate()

        If Not IsValid Then Return

        Dim cnn As New OleDb.OleDbConnection(ConfigurationSettings.AppSettings("SiteDB"))
        Dim cmd As New OleDb.OleDbCommand
        Dim IncomingFile As IO.FileInfo****
        Dim PriceValue As String
   

        If ImageSrc.PostedFile.ContentLength <> 0 Then
            IncomingFile = New IO.FileInfo(Request.Files(0).FileName)***
            IncomingFile = New IO.FileInfo(Server.MapPath("~/Pictures/Products/") & IncomingFile.Name)****
            Request.Files(0).SaveAs(IncomingFile.FullName)*******
         
        End If


        If Price.Text = "" Then
            PriceValue = "0"
        Else
            PriceValue = Price.Text
        End If

        cmd.CommandType = CommandType.Text
        cmd.CommandText = "INSERT INTO Products (Tier1ID, Tier2ID, Tier3ID, Name, " & _
            "Description, ImageSrc, Price, Weight, Size1, Size2, Size3, Size4, Size5, Size6, Size7, Size8, Size9, Size10) VALUES (" & Tier1.SelectedValue & ", " & _
            Tier2.SelectedValue & ", " & Tier3.SelectedValue & ", '" & ProductName.Text & _
            "', '" & Description.Text & "', '" & ImageSource & "', '" & PriceValue & "', " & Me.txtWeight.Text & _
            ", '" & Me.txtSize1.Text & "', '" & Me.txtSize2.Text & "', '" & Me.txtSize3.Text & "', '" & Me.txtSize4.Text & _

            "', '" & Me.txtSize8.Text & "', '" & Me.txtSize9.Text & "', '" & Me.txtSize10.Text & "')"
        cmd.Connection = cnn
        cnn.Open()
        cmd.ExecuteNonQuery()
        cnn.Close()
        cmd.Dispose()
        cnn.Dispose()
        LoadProductData()
