Not working... about lib-pdf

[GoogleCodeExporter]

No matter what I do....
Could not load file or assembly 'libpdf.dll' or one of its dependencies. The 
specified module could not be found

Hi Folks,

Depending on how/where you're using this you *may* need to load the library 
manually. I've found this was necessary when using it in an ASP.NET project.  
Apparently it is a bit of a bug in how the .NET runtime handles mixed c++ dlls..

// Add this code somewhere BEFORE you use the libpdf code
// Adds a handler to the AssemblyResolve event to manually load the libpdf 
library when the CLR fails to find it
AppDomain.CurrentDomain.AssemblyResolve += new 
ResolveEventHandler(currentDomain_AssemblyResolve);


    // Put this function somewhere else in you're code.. Remember to change the 'Path to libPDF' bit below!!
    // Resolve assemblies the CLR can't find/load
    Assembly currentDomain_AssemblyResolve(object sender, ResolveEventArgs args)
    {
        if (args.Name.StartsWith("libpdf"))
        {
            string libPDFPath = <PATH to libPDF>

            if (File.Exists(libPDFPath))
            {
                try
                {
                    ProxyDomain pd = new ProxyDomain();
                    return pd.LoadAssembly(libPDFPath);
                }
                catch (Exception ex)
                {
                    throw new Exception("Could not load libPDF: " + libPDFPath, ex);
                }
            }
            else throw new FileNotFoundException("Could not find libPDF: " + libPDFPath);
        }
        else return null;
    }

Oops.. forgot definition of ProxyDomain class. Here it is (from 
http://stackoverflow.com/questions/658498/how-to-load-assembly-to-appdomain-with
-all-references-recursively):


using System;
using System.Reflection;

/// <summary>
/// Summary description for ProxyDomain
/// </summary>
public class ProxyDomain : MarshalByRefObject
{
    public Assembly LoadAssembly(string AssemblyPath)
    {
        try
        {
            return Assembly.LoadFrom(AssemblyPath);
        }
        catch (Exception ex)
        {
            throw new InvalidOperationException("Failed to load assembly", ex);
        }
    }
}

This fix does not work, I still get the same error.
It appears that the zip file may be missing .dlls that are dependencies.
