Hi guys,
I need access to remote registry of Microsoft Window and get a data,
it's posible with Pascal?
of course it is possible... the question is how are you expecting
to be able
to perform this task...
Somebody can share one code?
no but possibly an idea or two... write a remote "server" that
accesses the
registry for whatever you want... then talk to it via a local
"client"...
in reality, it should be no different than using ssh or rdp into
the remote
host and starting the remote machine's regedit or similar...
capturing that
information and feeding it back across the link...
NOTE: i use the term "server" above because you are wanting to
connect to a
remote system and pull data from it... in the most general terms,
that makes
it a server... the connecting package on the local side is then
considered a
client...
I guess he means this:
http://msdn.microsoft.com/en-us/library/windows/desktop/ms724840%28v=vs.85%29.aspx
Currently this is not supported by FPC.
What needs to be done is implement
function TRegistry.RegistryConnect(const UNCName: string): Boolean;
begin
Result := False;
end;
in packages/fcl-registry/src.
The function indicated by Flavio must be used for this.
So I'd guess that would be something like:
function TRegistry.RegistryConnect(const UNCName: string): Boolean;
Var
Res : HKey;
begin
Result := RegConnectRegistryA(PAnsiChar(UNCName),FRootKey,@HKey);
if Result then
FCurentKey:=Res;
end;
Not entirely. According to the Delphi documentation RootKey needs to
be set instead of CurrentKey and also the key must be closed in the
end. I've already done the implementation and I'm currently testing it.
As a workaround for older FPC versions simply set RootKey to the value
returned by RegConnectRegistry.
Note: The login stuff mentioned on the MSDN page needs to be done
nevertheless.
Implemented in FPC revision 25332.
Attached is an example program that shows how to remotely connect to
another machine (this can also be used for using RegConnectRegistry
directly in case of FPC 2.6.2 and older). The machine name is given as
UNC name as first argument (e.g. "\\SomeComputer") and the username as
second argument. The password will be queried on the command line by
Windows. If the connection is successful the keys of HKEY_USERS of the
remote machine will be enumerated. Tested on a Windows 7 machine
connecting to another Windows 7 machine.
Note: The remote registry service must run on the destination machine.

Sven
