Problems with (anonymous) pipes with Win32

[Gnupg User]

I manage to make GnuPG-keys with "anonymous" pipes and
the --batch stuff, but I have no luck with --import...
This is on M$ NT4 and W2000 (don't flame me, it's for a
customer...).


"Pseudocode" for my sub I coded: (vars by refs)

sub GpgPipe( command, pipeout, pipein, pw )

	CreatePipes 	//

	CreateProcessA	// In PROCESS_INFORMATION StdOut & StdErr have same handle
			// Creationflag = DETACHED_PROCESS
	if( pipein )
		WriteFile( InWritePipe, pipein, ,, )

	if( pw )
		WriteFile( PwWritePipe, pw, ,, )

	ReadFile( OutReadPipe, pipeout, ,, ) // I loop until I read less then the 
bufsize

	WriteFile( InWritePipe, "exit<cr><lf>", ,, ) // Workaround to exit the 
gpg.exe-process

	ClosePipeHandles

	WaitForExitCode( !STILL_ACTIVE )

	CloseProcessHandles

end sub

command = "gpg --yes --batch --gen-key"
batch = "<Some batch lines from doc examples>"
GpgPipe( command, resp, batch, "" ) // Works
DoSomeThingWith( resp )

command = "gpg --fingerprint " + user
GpgPipe( command, resp, "", "" ) // Works
DoSomeThingWith( resp )

command = "gpg --export -a"
GpgPipe( command, resp, "", "" ) // Works
DoSomeThingWith( resp )

// But
public_key = "<some public key text>"
command = "gpg --import"
GpgPipe( command, resp, public_key, "" ) // Does NOT work!!!!
DoSomeThingWith( resp )

"End Pseudo"

I have tried "command-lines" like:
gpg --import
gpg --import -
gpg --no-tty --import
gpg --no-tty --import -
gpg --batch --import
gpg --batch --import -
gpg --batch --no-tty --import
gpg --batch --no-tty --import -

cmd /C gpg --import
cmd /C gpg --import -
cmd /C gpg --no-tty --import
cmd /C gpg --no-tty --import -
cmd /C gpg --batch --import
cmd /C gpg --batch --import -
cmd /C gpg --batch --no-tty --import
cmd /C gpg --batch --no-tty --import -

With no success!!!! :-(

Everything above works from "CMD" like:
type <some armored public key file> | gpg --import


Questions:

Do I need to have the --batch parameter?

Do I need to append some line with "%commit" to
the "pipein-key" to let gpg submit the StdIn?

Or is it only the --gen-key command which allows StidIn/Pipe?

Or maybe it's fixed in >=1.0.6a ?


Best Regards

PS
One more thing, I don't understand why it's not possible to
get the fingerprint/info from an armored public key file
without import it or generate some temp-key?
