Inbuilt Upload?

**Kings** · Apr 29th, 2002, 11:30 AM

I heard that uploading is already in ASP.NET?

Anyone else know this? And knows how to do it?

Modified(C# to VB) code sample I **believe** I got from www.aspalliance.com. Only allows GIF or JPG but can be easily modified. Allows upto 5 files to be uploaded at one time. Obviously, the paths for saving the image must be changed to your configuration.

Code:

<%@ Page Language="vb" %>
<script runat="server">
  Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        If (Me.IsPostBack) Then Me.SaveImages()
    End Sub

Private Function SaveImages() As System.Boolean
        '//loop through the files uploaded
        Dim _files As System.Web.HttpFileCollection = System.Web.HttpContext.Current.Request.Files

        '//Message to the user
        Dim _message As New System.Text.StringBuilder("Files Uploaded:<br><br>")
        Dim _iFile As System.Int32
        Try

            For _iFile = 0 To _files.Count - 1

                '// Check to make sure the uploaded file is a jpg or gif

                Dim _postedFile As System.Web.HttpPostedFile = _files(_iFile)
                Dim _fileName, _fileExtension As System.String

                _fileName = System.IO.Path.GetFileName(_postedFile.FileName)

                If _fileName <> "" Then 

                    _fileExtension = System.IO.Path.GetExtension(_fileName)

                    If (_fileExtension = ".gif") Then

                        '//Save File to the proper directory
                        _postedFile.SaveAs("\images\GIF\" + _fileName)

                        _message.Append(_fileName + " successfully uploaded.<BR>")

                    ElseIf (_fileExtension = ".jpg") Then

                        '//Save File to the proper directory				
                        _postedFile.SaveAs("\images\JPG\" + _fileName)

                        _message.Append(_fileName + " successfully uploaded.<BR>")

                    Else
                        _message.Append(_fileName & " <font color=""red"">failed!! Only .gif and .jpg images allowed!</font> <BR>")
                    End If
                End If 
            Next

            Label1.Text = _message.ToString()
            Return True
        Catch Ex As System.Exception
            Label1.Text = Ex.Message
            Return False

        End Try

    End Function

Nice example,

I have done a similar thing on a site we use, but also allows you to navigate a directory tree to select the upload folder (limited of course) required, create sub folders, and upload other non executable file formats. Once the upload has succeeded then the file properties are displayed in a status area of the screen.

what am I doing wrong? I can't get it to work. All I ever get is a 0 count on the ofiles.Count line.

Code:

Public Class upload
    Inherits System.Web.UI.Page
    Protected WithEvents File1 As System.Web.UI.HtmlControls.HtmlInputFile
    Protected WithEvents Button1 As System.Web.UI.WebControls.Button

    Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        'Put user code to initialize the page here
        If IsPostBack = True Then Upload_File()

    End Sub

    Sub Upload_File()

        Dim ofiles As System.Web.HttpFileCollection = System.Web.HttpContext.Current.Request.Files
        If ofiles.Count > 0 Then
            Dim HPFpostedFile As System.Web.HttpPostedFile = ofiles(1)
            Dim sfileName As String

            sfileName = System.IO.Path.GetFileName(HPFpostedFile.FileName)

            '//Save File to the proper directory				
            HPFpostedFile.SaveAs("\reg\" + sfileName)

            Response.Write("IT FREAKING WORKED!")
        Else
            Response.Write("Not working")
        End If

    End Sub

End Class

I figured it out..

Code:

<form id="UPLOAD" method="post" runat="server" enctype="multipart/form-data">

was missing the enctype thing..

**Dmyze** · Aug 27th, 2002, 07:04 PM

Now that i have it figued out, here is a real simple way to do it:

Code:

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        fSend.PostedFile.SaveAs("C:\" & System.IO.Path.GetFileName(fSend.PostedFile.FileName))

    End Sub

<%@ Page Language="vb" AutoEventWireup="false" Codebehind="upload.aspx.vb" Inherits="DartS.upload"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">

	<HEAD>

	<body MS_POSITIONING="GridLayout">

			&nbsp;
			<asp:button id="Button1" style="Z-INDEX: 101; LEFT: 36px; POSITION: absolute; TOP: 271px" 
			runat="server" Text="Button"></asp:button>
			<INPUT id="fSend" style="Z-INDEX: 103; LEFT: 30px; POSITION: absolute; TOP: 218px" 
			type="file" name="File1" runat="server">
		</form>
	</body>
