Getting the type by address in WinDbg

Suppose I have an address of some object placed in unmanaged heap. How can I get the C++ type of the object in WinDbg?

This isn't foolproof, but it often works.

  1. Run !heap -x ADDR. This will provide the user pointer.
  2. Run dps USERPOINTER. For a C++ object, this will usually give you a vtable symbol name.
