Dumping Process Memory To File

I need to create a way to dump the memory of a process to a file. And I don't mean a crash dump, I mean dumping the memory. In C++ you can use the function MiniDumpWriteDump.

Here is my code so far:
Public Declare Function MiniDumpWriteDump Lib "dbghelp.dll" (ByVal hProcess _
As IntPtr, ByVal ProcessId As Int32, ByVal hFile As IntPtr, ByVal DumpType _
As mydumptypes, ByVal ExceptionParam As IntPtr, ByVal UserStreamParam As _
IntPtr, ByVal CallackParam As IntPtr) As Boolean
Enum mydumptypes
[Code] .....

A file is created, however when I looked inside the file with a hex editor, it was complete garbage. For a test, I opened notepad, typed in "Hello!", and dumped the notepad process. I could not find any strings in it, let alone the "Hello!" string.

mydumptypes.normal =
MiniDumpWithDataSegs= 0x00000001,
in c++. It wasn't what I wanted. Anyways, I fixed it.
