Thanks for sharing, Harley.

Yes, this is an interesting issue. Particularly in the project I’m working on now. The .Net objects are instantiated from a Windows service written in C++. The executable’s location may not really have anything to do with the .Net locations. And to further complicate things, the deployment/installation environment may be different than the debug/development environment. And sometimes Location is relative and sometimes it’s absolute.

I ended up having to search multiple locations:
private static IEnumerable GetSearchLocations()
{
return new[] { Assembly.GetExecutingAssembly(),
Assembly.GetEntryAssembly(),
Assembly.GetCallingAssembly() }
.Where( a => a != null )
.Select( a => Path.GetDirectoryName( Path.GetFullPath( a.Location ) ) )
.Concat( new[] { GetStartupDirectory() } )
.Distinct();
}

private static string GetStartupDirectory()
{
var argsPointer = GetCommandLine();
var args = Marshal.PtrToStringAuto( argsPointer );
if( string.IsNullOrEmpty( args ) )
return string.Empty;
var parseChar = args[0] == '\"' ? '\"' : ' ';
var parameters = args.Split( parseChar );
return Path.GetDirectoryName( parameters[parseChar == ' ' ? 0 : 1] );
}

Cheers,
Harley

Sir this tutorial is really great.. Very very thanks… I installed Zimbra 7.1 on Centos 5.7 with the help of this ………………. Very very Thanksful 2 u.

I have an older 32-bit Zimbra running on CentOS 5 that is slated for upgrade (read: clean install and copy data), but actually doing it hasn’t made it on to the calendar.
