hello,

i have built and have successfuly installed and used the sample mini filter
keyboard driver from the WDK samples.

i have modified the DriverEntry function to call FltRegisterFilter....and i
get a linker error....'unresolved external symbol _FltRegisterFilter(a)12'.

i am sure this function lives in fltMgr.lib, and i have used dumpbin.exe on
this lib file and i have seen FltRegisterFilter in there.

so, i have tried two things, both of which have had no effect:

1) in the SOURCES file (which is called from the MAKEFILE) i have added the
line:

LIBRARIES=C:\WinDDK\6777\lib\wlh\i386\fltMgr.lib

2) added a pragma in the c file:

#pragma comment(lib, "C:\\WinDDK\\6777\\lib\\wlh\\i386\\fltMgr.lib")

as you can see i have put the full path to the lib just to make sure.

i am using the following command line to build the driver:

build -cewgZ

i have tried with the checked and free build environments.
i am on vista home premium 32 bit.

can anyone please explain what i am doing wrong...if i have not given enough
info let me know...
thanks in advance.

Keyboard filter drivers and file system minifilters are entirely different
beasts. What are you trying to do?
