    Hi,

    I am getting the following error when i am trying to create the file.

    The code is falling over on the following line

    Dim s As New StreamWriter(Server.MapPath(strFileName))

    Invalid path for MapPath 'e:\inetpub\wwwroot\internet site\quotes\clikpayorders\771001843-000011.ord'. A virtual path is expected

    Can someone help me please
    Private CLICK_PAY_F As String = esConfig.getSetting("ClickPayF")
Private MERCHANT_ID As String = esConfig.getSetting("MerchantID")
Dim f As File
Dim strFileName As String
Dim strOrderDetail As String

strFileName = CLICK_PAY_F & MERCHANT_ID & "-" & strHexNumber & ".ord"

Dim s As New StreamWriter(Server.MapPath(strFileName))

s.Write(strOrderDetail)

    if you have the full path (e:\inetpub\wwwroot\internet site\quotes\clikpayorders\771001843-000011.ord) you don't need to use server.mappath

    server.mappath should get you (e:\inetpub\wwwroot\internet site\quotes\clikpayorders\771001843-000011.ord)

    you could do server.mappath("771001843-000011.ord") if it is the same folder as the code that is running or something like server.mappath("/site/quotes/clikpayorders/771001843-000011.ord")

    or alternatively you can get rid of server.mappath and just have the filename in there.

    As far as I am aware, Server.MapPath can only be used to reference locations on that server - and not on an external one.

    What exactly are you trying to do?

    Try using the ~

    I had simialr problems trying to upload images at one stage.


    Absolute and relative path references in a server control have the following disadvantages:

    Absolute paths are not portable between applications. If you move the application that the absolute path points to, the links will break.

    Relative paths in the style of client elements can be difficult to maintain if you move resources or pages to different folders.



    ASP.NET includes the Web application root operator (~), which you can use when specifying a path in server controls. ASP.NET resolves the ~ operator to the root of the current application. You can use the ~ operator in conjunction with folders to specify a path that is based on the current root.
