Problem with CultureInfo

[todorov-fkt]

Hello,

I have packed a few images into resources files and compiled those files
into a resource dll. The dll has a static function that returns all of the
images. When I try to use the function in an application I get the following
exception (in translation from German):

"A not handled exception of type
'System.Resources.MissingManifestResourceException ' occured in mscorlib.dll

Additional information: For the given culture or the neutral culture no
resource was found in the assembly. Make sure that
'CountryFlagsBevelSmall.resources' is correctly embeded in the assemby.
baseName: CountryFlagsBevelSmall locationInfo: <null> resource file
name: CountryFlagsBevelSmall.resources assembly: MedLibIcons,
Version=1.0.1736.29728, Culture=neutral, PublicKeyToken=fb80360726c11ad7"

The resource file exists and ILDASM shows in the manifest of the dll:
..mresource public MedLibIcons.CountryFlagsBevelSmall.resources
{
}

The function that return the image is the following:
public static Hashtable GetImage(string imgName)
{
ResourceManager rm = new ResourceManager("CountryFlagsBevelSmall",

Assembly.GetExecutingAssembly));
IDictionaryEumerator ide =
rm.GetResourceSet(new CultureInfo(""), false,
true).GetEnumerator();
Hashtable table = new Hashtable();
while (ide.MoveNext())
{
table.Add(ide.Key as string, ide.Value as Image);
}
return table;
}

The docs say that CiltureInfo("") returns the invariant culture which should
work anywhere, where no comparison depending on localization is needed, and
since I do no localized stuff it is good enough for me. And yet I get this
execption?

Additional information: my Windows is German, Visual Studio as well. The
localization of my app is set to "(Standard)".

Any hints please?
