DUN Rasdial disconnecting issue

Hi experts,

I made an application that uses the RasApi to stablish a Dial-up connection with a local ISP. Everything works like a charm except I can't "cancel" the connection.

While it is dialing and authentificating there is a cancel button in my form, if the user click on it I call rashangup to cancel the connection with a loop to check for the "disconnected" error (6).

This works fine, but the connection never gets disconnected.

I have no clue what the problem might be.

Any ideas?

Thanks,

Esopo.

Ok, I just realized why my code isn't working. It uses RasEnumConnections to get the pending connection but it won't return any. So I can't call RasHangUp on my connection, or can I ?

Of course that's why RasGetConnectStatus return ERROR_INVALID_HANDLE - "The specified port is not connected".



please check out this Q, it has the code I'm using (or if you'd like I can post it here):

Thanks in advanced,

BTW I'm also posting another Q here about this RasEnumConnections issue, this is rather urgent.

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

Delphi is about my weakest language, (except for english)

Your problem with RasEnumConnections (I think)
is that  a RASCONN structure needs to be created, then set dwsize to 412

var
  RasConn  : TRasConn;
  bsize    : DWORD;
  Count    :  DWORD;
begin
  RasConn.dwSize := 412;

I think you have another one of these open... That I am working on, Like I was indicating on the other thread,
Just use rashangup on the RASCONN handle that you got from the connection

Using the handle the Rasdial gave me worked. As I said in the other Q I called RasHangUp with the Handle RasDial returned and seems to be working properly.

I am still wondering why isn't RasEnumConnections returning my pending connection?
Does a conection need to be fully stablish to appear there? It seemed to show the dialing connections in Win98 (not 100% sure but I think so).

Anyway, is there a way to get the handle for the pending connections that RasEnumConnections won't give me?

I htink rasenum isn't returning because the handle your passing it is not configured right..??

try initializing all values to (0) except for dwsize, set that to 412

unlikely, but it maybe possible to guess at the address of a given connection if you can scan the heap?!?

(REALLY DANGEROUS STUFF)

Kavar,
What you posted did not really solve my problem, but hey!, it was a very vague question anyway, thanks for trying. At least I got a new thing to look for when playing with RAS.

Venabili,
Sorry to waist your administrative time, I'll try to see to it that my Q's don't go unatended for so long in the future.
