view source

[John A Grandy]

In VB.NET / ASP.NET, I am trying to provide a "view source" button on my
..aspx page which, when pressed, would cause the browser to show the
underlying html/aspx source code for the current page

ASP.NET *dynamically* creates the actual .aspx pages which are delivered to
the client. The delivered pages may differ from the initial static .aspx
pages which are located at (for example) :

c:\inetpub\wwwroot\webapplication1\webform1.aspx

On the client side, the page viewed will exist as a local file located on
the client machine at (for example):

c:\documents and settings\<user name>\local settings\temporary internet
files\webform1.aspx

(w2k, ie6)

On the server side, I don't know where the **dynamically** generated file is
located.

If I knew where the dynamic file was located, potentially I could somehow
use Response.WriteFile() to send the contents across ... ?

Interesting Phil. But I'd like to do it using ASP WebControls ... I want to
get away from editing HTML. Plus, I tried interspersing that code into the
design view of the aspx page and it's tough to figure out how to place it.

What I've been doing is trying a LinkButton with this code behind it:

Dim fsCurrentPage As FileStream

Dim strFullPathCurrentPage As String

strFullPathCurrentPage =
Server.MapPath(Request.ServerVariables("PATH_INFO"))

fsCurrentPage = New FileStream(strFullPathCurrentPage, FileMode.Open)

Response.Write(Server.HtmlEncode(fsCurrentPage.ToString()))

but I got a security error; strangely, the {machinename}\ASP.NET process
does not have rights directly access the aspx files in

c:\inetpub\wwwroot\<app name>

I wonder if there was some way to use a virtual path to grab a file, then
the security error would go away

John: Try this:

Private Sub Page_Load(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles MyBase.Load

Dim script As String = "<script language=""javascript"">" & _
"function viewSource() { window.location = " & _
"'view-source:' + window.location.href }</script>"
RegisterClientScriptBlock("ViewSource", script)

End Sub

Then set your HyperLink's .NavigateURL property to
"javascript:viewSource()".
