HTML "FileField" control

[wsyeager]

I'm using the HTML "FileField" control to browse to a file. Once it's selected, I then use a linkbutton to try and upload the file to the app.

 

This works fine if the webserver is local to my machine. However, once the app is on another webserver instead of my local machine, it can't find the file.

 

I tried putting a file on our development web server to access. When I browse to the exact same filename on my local machine, it finds the file only because it exists on the webserver. This means that the "Browse" button of the control is looking on the webserver, not the users' local machine.

 

Therefore, how do I update the pathname of the file to get the correct file from the users' machine and not the webserver?

I've tried implementing the code you supplied, but this just reads data inside the actual file being uploaded. I just want to get the pathname of the file?

 

I'm using the following code:

<code>

Dim filecontrol As HtmlControls.HtmlInputFile

filecontrol = DirectCast(Me.FindControl("ffRequestDoc"), HtmlControls.HtmlInputFile)

Dim strReqFrmDoc As String = filecontrol.PostedFile.FileName

</code>

 

However, like I said before, it's giving me problems accessing the correct path when I access my app from a web server other than my local machine.

 

How can I resolve this?

Like I said in the other thread, a web server cannot access files on a client's machine. The .FileName property will give you the path of the file on the client - this can be useful if you need to store the posted file somewhere on the web server and wish to give it a name, but it will not allow the server to access the file on the client.

I got it now...

 

After browsing to the file with the input control, I then use a linkbutton to actually add the document to a collection and eventually add it to SQL Server as follows:

 

<code>

Dim filecontrol As HtmlControls.HtmlInputFile

filecontrol = DirectCast(Me.FindControl("ffRequestDoc"), HtmlControls.HtmlInputFile)

Dim txtDetailedDescr As TextBox = DirectCast(Me.FindControl("txtDetailedDescr"), TextBox)

Dim sr As New StreamReader(filecontrol.PostedFile.InputStream)

.

.

.

'Add attachments to collection

Dim drAttachments As dstRequests.AttachmentsRow = DstRequests1.Attachments.NewAttachmentsRow

drAttachments.AttachmentName = strAttachmentName

drAttachments.AttachmentDescription = txtDetailedDescr.Text.Trim

drAttachments.FileType = filecontrol.PostedFile.ContentType

drAttachments.PathName = filecontrol.PostedFile.FileName

drAttachments.FileLength = filecontrol.PostedFile.ContentLength

drAttachments.UserLastModified = HttpContext.Current.User.Identity.Name

drAttachments.DateLastModified = Convert.ToDateTime(ViewState.Item("PresentDate"))

Dim content() As [byte] = New Byte(filecontrol.PostedFile.ContentLength) {}

drAttachments.FileData = content

DstRequests1.Attachments.AddAttachmentsRow(drAttachments)

</code>

 

I know there is a way in the web.config file to increase the size limit of the file attachment. Do you happen to know what it is?

 

Thanks much.......
