Hi All,
(As an aside I'm new to this list)
We've been working with a VS.NET solution that includes an ASP.NET project
and we've been using Nant to create an automated build and test environment.
We had some problems getting a nant build script for the solution and ended
up just exec-ing the devenv.exe.
I found 2 issues:
1. Using the <slingshot> command through nant always gives a error about
build.basedir. I've tried a couple of combinations but with no luck. the
failing script looks like:
<target name="Slingshot" description="Use Slingshot">
<slingshot solution="C:\projects\WebSolution.sln" format="nant"
output="Slingshot.build">
<parameters>
<option name="build.basedir" value="."/>
</parameters>
</slingshot>
</target>
if anyone can give me any pointers it would be appreciated.
2. After failing with that we took a look at the Slingshot.exe itself and
this gave an error when compiling project references for the ASP.NET project
within the solution.
We had structured our solution as outlined by the Microsoft roadmap for Team
development of .NET solutions. This meant not allowing VS.NET to
automatically create IIS web directories, under c;\inetpub\wwwroot\, for the
ASP.NET application but instead manually creating a Blank Solution first and
then adding the directory structure beneath it, to give something like;
c:\project\MyNewApp\MyNewAppSolution\MyNewWebApp
and then manually mapping the MyNewWebApp directory to be a virtual
directory under IIS and then adding a new ASP.NET project into the blank
solution using http://localhost/MyNewWebApp as its location.
To cut an increasingly long story short this structure seemed to confuse
Slingshot when it tried to build up the correct path to referenced dlls,
producing the following error:
Unhandled Exception: System.NotSupportedException: The given path's format
is not supported.

Boolean needFullPath)

textWriter, String sln, Hashtable parameters, Hashtable uriMap)

A bit of investigation showed the error to be at around line 300 in
driver.cs:
path = Path.GetFullPath( solution.SolutionDirectory + "\\"
+ project.RelativePath + "\\" + path );
For our ASP.NET project structure project.RelativePath is not a RelativePath
it is absolute.
Adding the following test seems to have fixed it:
if(Path.IsPathRooted(project.RelativePath))
path = GetWebProjectReferencePath(project.RelativePath, path);
else
path = Path.GetFullPath( solution.SolutionDirectory + "\\"
+ project.RelativePath + "\\" + path );

private static string GetWebProjectReferencePath(string ProjectPath, string

{
string Delimiters = "\\";
char [] DelimiterArray = Delimiters.ToCharArray();
string [] Directories = null;

int MaxDirCount = 100;
Directories = ProjectPath.Split(DelimiterArray, MaxDirCount);

//so only count the zero-based GetUpperBound value
int ProjectDirLevelCount = Directories.GetUpperBound(0);
string ProjectDrive = Directories[0];
//get ".." count
Directories = ReferencePath.Split(DelimiterArray, MaxDirCount);
string ReferenceAbsolutePath = "";
int ReferenceDirLevelCount = 0;
for(int i=0;i<=Directories.GetUpperBound(0);i++)
{
if(Directories[i] == "..")
ReferenceDirLevelCount++;
else
ReferenceAbsolutePath = ReferenceAbsolutePath + "\\"
+ Directories[i];
}
ReferenceAbsolutePath = ProjectDrive + ReferenceAbsolutePath;
/* if we have no directories it must be a local copy - Case 1.
* if the directory counts match then do the standard path building -
Case 2.
* otherwise take a view and use one constrcuted using the following

* b. The relative path is always taking us back to the root
directory first.
* ... Case 3.
* */
//Case 3.
if(ReferenceDirLevelCount==0)
return Path.GetFullPath( ProjectPath + "\\" + ReferencePath
);
//Case 2.
else if(ProjectDirLevelCount == ReferenceDirLevelCount)
return Path.GetFullPath( ProjectPath + "\\" + ReferencePath
);
//Case 1.
else
return ReferenceAbsolutePath;
}
I don't know if this is a known problem, or one that has already been fixed,
but looking at line 140 of source.cs it loks like this would be common to
all ASP.NET projects, but I could easily be wrong about that?
string relativeProjectPath = Path.GetDirectoryName(path);
project.RelativePath = relativeProjectPath;
Being new to the sourceforge/open source world I wouldn't have the foggiest
about how to get this change approved, tested, etc and into the actual
slingshot code rather than my local version.

Mike
