Scenario: I have HtmlInputFile ctrls File_1 to File_5
In the Button_Click method with Script language as VB and runat =server i
have to upload the files.
I want to loop through these controls and want to access the properties and
methods of the htmlinputfile objects..
How do i go about this ?

Is there any method like there was "eval" in javascript ??

Thanks

Maybe this will help. The following code runs through text box controls on
an aspx page and fills them with data from SQL:

/* Find the ContentPane TD tag, access Control zero
* which will be this control, cast appropriately,
* and run though all the controls inside the 'container'
* (i.e., TextBox, ListBox, Label).
* To check if control is a web control textbox,
* attempt cast via as keyword. TextBox IDs match
* DB fields. Load the value.                        */

UserControl container =
(UserControl)Page.FindControl("ContentPane").Controls[0];

foreach ( Control ct in container.Controls )
{
    TextBox t = ct as TextBox;
    if ( t != null )
        t.Text = rc[0][t.ID].ToString();
}

Sorry it's C#. I don't know if there's an eval keyword, but I doubt it.

Good luck.

Michael

Hi,

I've done this before in VB (by accident) and never thought it'd come in handy, so here you go:

'' First grab the posted file collection from request
Dim _files As System.Web.HttpFileCollection = System.Web.HttpContext.Current.Request.Files

Try
Dim _iFile As Integer = 0
uData.WordCount = 0

''' now loop through them
For _iFile = 0 To (_files.Count - 1)

'' Access the individual posted file
Dim _postedFile As System.Web.HttpPostedFile = _files(_iFile)

'' Now we can fiddle around with it
Dim _fileName As String = System.IO.Path.GetFileName(_postedFile.FileName)
Dim _fileExtension As String = System.IO.Path.GetExtension(_fileName)
Next
Catch ex as System.Exception
Me.Response.Write(ex.ToString)
End Try

Hope this helps.
