What is a module handle?
The HMODULE, or HINSTANCE is the address within the virtual memory where the particular module is loaded. You can use GetModuleInstance() or LoadLibrary() API calls to get the handles.
How do I handle a DLL?
Implementing DllMain() and saving the hinstDLL argument value is by far the easiest way to get it. GetModuleHandle(“yourdllname”) should work too. Using VirtualQuery() on your DLL function’s address and casting the returned AllocationBase to HMODULE is yet another one.
What is a process module windows?
A module is an executable file or DLL. Each process consists of one or more modules. This function fills an array of HMODULE values with the module handles for the specified process. The first module is the executable file.

What is KERNEL32 DLL used for?
KERNEL32. DLL exposes to applications most of the Win32 base APIs, such as memory management, input/output (I/O) operations, process and thread creation, and synchronization functions. Many of these are implemented within KERNEL32.
What is the process of module?
A Process Module is a set of process elements that can be added to other processes.

In effect, this is the sum of all handles that this process has open.

What to do with the getmodulehandle function?
To work around this problem, you could specify a path, use side-by-side assemblies, or use GetModuleHandleEx to specify a memory location rather than a DLL name. The GetModuleHandle function returns a handle to a mapped module without incrementing its reference count.
