The best profiler for this aim you can find is you yourself...
Memory leaks are not a problem of the system or of somebody else but only
of your own code (and in addition maybe of some third party code referenced
in your project - where usually you can't do anything to avoid it).
There are some simple rules to avoid memory leaks:
b) Reselect >always< the original objects into e.g. device contexts.
a) Destroy >every< GDI object you have created unless the MSDN
documentation states explicitely that you don't have to do so.
b) Free >all< memory you have allocated unless the MSDN documentation
states explicitely that you don't have to do so.
c) Don't used the VB statement "End"
d) Use global variables only were they really can't be avoided. Often
global variables are the reason for the developer to have lost control of
his code.
For a) and b) it is essentially important that you are tracking the way of
all GDI object handles and allocated memory handles, so that you don't get
lost of a handle before you have destroyed the respective object or freed
the respective memory.
