Hi All,
Is there a way to determine if a Dll is a Com Dll or a .Net Dll ?
Any pointers are greatly appreciated.
Thanks,

why not just point ILDASM at the DLL. If it's not .NET, you will find out
quickly.

Hi
I too got around with this same problem, but i've the solution only if it is
a VB5 or VB6 COM Dll. In the above two, the Dll Binary file will have a text
called MSVBVM (Microsoft Visual Basic Virtual Machine). So what you could do
is, in the Search->Files, goto the containing text and type "MSVBVM", so it
would list all the VB -COM Dlls

Look for the CLR header, this is documented in the ECMA spec.
DOS header starts at 0x0, the DWORD at 0x3c contains a pointer to the PE
signature (usually 0x80) which is 4 bytes, the next 20 bytes is the COFF
header and then there is the PE header (at 0x98). The PE header is 224 bytes
and contains the data directory (at 96 bytes into the PE header = 0xf8). The
15th entry (at 0x168) is the CLR header descriptor (sometimes called the COM
descriptor, but this does not have anything to do with COM). If this is
empty (ie 0 in the 8 bytes from 0x168 to 0x16f) then the file is not a .NET
assembly. If you want to check if it is a COM DLL then you should look to
see if it exports GetClassObject.
Note that these offsets will be different for 64-bit DLLs.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
