Reading Windows Registry

[emferrari]

Hi all

I need to make a program that will loop inside the HKEY_CLASSES_ROOT
and find the name of the DLL associated with a ClassID.

I want to know how can I possible loop inside the classes id ?

I tried to look into the documentation of the RegistryKey class but I
didn't find something useful.

Thanks!

using (RegistryKey keyClsid =
Registry.ClassesRoot.OpenSubKey("CLSID"))
{
foreach (string subKeyName in keyClsid.GetSubKeyNames())
{
using (RegistryKey subkey = keyClsid.OpenSubKey(subKeyName))
{
// do something
}
}
}

I suspect that RegistryKey.GetSubKeyNames() is what you're after.

Eduardo,

You will want to look for the following path:

HKEY_CLASSES_ROOT\CLSID\<clsid>\InProcServer32

Then, you want to get the default value, which should be the path to the
assembly.

<clsid> is the clsid of the component in registry format (with curly
braces).

Hope this helps.

Hi

This was very helpful. But what I should do in this case ?

I'm looking for the assemble name for the MSI.DLL, and the only thing I
can find by the class id is in:

HKEY_CLASSES_ROOT\TypeLib\{000C1092-0000-0000-C000-000000000046}

Thanks!
