Server-Side Include "Failed to map the path"

Problem
In a VS2005 web site solution, the following server-side include:


throws the following error:
Failed to map the path '/MyIncludeFile.inc'.

Web site must be set up in solution as a "Local IIS" or with a Location of "HTTP" rather than "File System".

See quote from "Using IIS with VS 2005 and the new Web Project system - ScottGu's Blog":

The file-system tab option is great if you are working on a self-contained web project that requires no knowledge of the directory or URL structure of content outside its structure.

However, if you are using multiple nested IIS applications or special IIS virtual directory rules on your web server to coordinate multiple applications, then you should avoid opening up these projects using the file-system web option – and instead open them using the “Local IIS” or “Remote Site” tab options. The reason for this is because these nesting and relationship rules are stored in the IIS metabase, and for your application to properly run you will want/need these IIS bindings and semantics to be handled both at runtime and inside VS 2005.

Solution

DTE.ActiveDocument.Selection Missing Inellisense in Macro

Problem
Can not access properties of Selection object through intellisense in VS macro using Visual Studio Automation and Extensibility.

Solution
To use the Selection property of a text file such as program source code, it must first be cast to a TextSelection:

VB.NET
Dim selection As TextSelection = CType(DTE.ActiveDocument.Selection, TextSelection)

C#.NET
TextSelection selection = (TextSelection)DTE.ActiveDocument.Selection;

File vwd.webinfo containing StartupServices with Service ID of {967B4E0D-AD0C-4609-AB67-0FA40C0206D8} keeps adding itself to ASP.NET 2.0 web site.

This was related to a past reference to Crystal Reports.

If you delete this within Visual Studio 2005, it is regenerated after closing solution.

Solution
1) Close Visual Studio
2) Open Windows Explorer
3) Delete vwd.webinfo

DataFormatString Not Working

Problem
GridView BoundField DataFormatString not working.

Solution
Specify HtmlEncode="false".

<asp:boundfield datafield="MyDataColumn" headertext="Col Hdr" DataFormatString="{0:p}" HtmlEncode="false"/>

See Microsoft note:

When the HtmlEncode property is true, the value of the field is HTML encoded to its string representation before the formatting string is applied. For some objects, such as dates, you might want to control how the object is displayed with a formatting string. In those cases, you must set the HtmlEncode property to false.
