internetclosehandle api hangs up my program

Hi!

I hope you can help me

When I issue a InternetCloseHande(lngHndConnection) my progrma hangs up. I use windows 2000 sp4, VB 6 sp6

the sentences are

Private Declare Function InternetOpen Lib "wininet.dll" Alias "InternetOpenA" (ByVal sAgent As String, ByVal lAccessType As Long, ByVal sProxyName As String, ByVal sProxyBypass As String, ByVal lFlags As Long) As Long

Private Declare Function InternetConnect Lib "wininet.dll" Alias "InternetConnectA" (ByVal hInternetSession As Long, ByVal sServerName As String, ByVal nServerPort As Integer, ByVal sUsername As String, ByVal sPassword As String, ByVal lService As Long, ByVal lFlags As Long, ByVal lContext As Long) As Long

Private Declare Function InternetCloseHandle Lib "wininet.dll" (ByVal hInet As Long) As Integer

sub x()

lngHndOpen = InternetOpen(strUserAgent, INTERNET_OPEN_TYPE_DIRECT, vbNullString, vbNullString, 0)
If lngHndOpen <> 0 Then
lngHndConnection = InternetConnect(lngHndOpen, strIpAdd, INTERNET_INVALID_PORT_NUMBER, strUser, strPwd, INTERNET_SERVICE_FTP, 0, 0)
InternetCloseHandle lngHndConnection 'program stops here
InternetCloseHandle lngHndOpen
endif

end sub

I’d really appreciate your help

thank you in advance.
