Hello again :-)...doesnt that only work under win98/95? Because I need it to work under Win95/98/2000/NT4 etc...Thanks

winnt is more secure .
i dont believe you will get code for nt.

okay, well I am gonna reinstall win98 and I will try it out after I do that...I should accept your anwser within a few hours ;] Thanx

reinstall huh- that always a pain

the code works fine on win9* pcs (it did work on earlier versions of nt depended what version of mpr.dll is install ,but most ms products overwrite mpr.dll with new versions so most likely wont work nowadays on any winnt type pcs and certainly not on win2k.

but that is the point in using winnt for networking etc type apps as its has good security ..

well i re-answer becuase i know you wont find any other code for delphi..

Listening...

listenning

Alright I tried it and I always get the error "User not logged in" or whatever it is...why is it doing this??? Helo!

the only way to get  a password with delphi s if a user has loged in .
on most pcs you enter a password to login ytou your pc so you have a username etc ..
if you have no username (or not logged in)you will get that result,it is not an error it just has no cached passwords to read.

rejecting my answer is a bit pitiful as like i already said you wont find any other code for delphi .
you were lucky to get WNetEnumCachedPasswords function as it is certainly not documented anywhere.
other passwords are stored in the *.pwl files which are encrypted.
