Hello,
My TSP accesses registry to get the details of the
configuration. To access the proper registry, I am trying to retrieve
the session ID of the user and then retrieve the other details. To get
the session ID, for XP OS, I am enumerating all the processes and
trying to find the "explorer.exe". But when I reboot the PC, the PC
hangs for some time and then starts properly. The issue is with my
TSP, without the TSP everything works fine.
When the PC starts up, telephony services will start
initializing before explorer.exe starts up. Hence my TSP couldnt find
the explorer.exe and behaves wrongly. Is there anyway to solve this
problem?
Please help me to solve this issue.
Regards,
Gomathy |

Gomathy,
a TSP is required to operate correctly even if no user is currently logged on,
e.g. when TAPISRV is starting up at boot time due automatic startup mode for
telephony service.
So making a TSP dependant on a currently logged on user isn't a good idea at
all.
If you absolutely reqire this, then you need to special handle this scenario
within your TSP,
e.g. by deferring the access to HKEY_CURRENT_USER since a user has actually
logged on.
Of course your TSP may not block TAPISRV in any way!
BTW here is a discussion on how to get access to the currently logged on
user's resources:

Andreas and Gomathy,
just at this moment while I'm reading, a much better method comes to
my mind. This is based on the TAPI method for displaying a dialog
within the TAPI application. You can send LINE_CREATEDIALOGINSTANCE
from within your TSP. As a result TAPI will call
TUISPI_providerGenericDialog
in your TSP UI dll, but from within the process of the TAPI
application(!!!).
You do not need to actually create a dialog, you can just use this mechanism
to communicate with something running in the process space of the user.
You can transmit data blocks from your TSP to the UI dll and vice versa
(through TUISPIDLLCALLBACK).
With this mechanism you should be able to discover all information about
the user's session in a supported and safe way.

Hi Andreas and Matthias,
Thank u so much for your response. The API RPCImpersonate
Client returns error 1725. I donno how to implement
ImpersonateLoggedOnUser() function also.
I need to access the current user account in the registry.
I am not able to understand Matthias idea too... :(
Any code snippet available?
Please help me to solve this issue.
Thanks & Regards,
Gomathy |

You should read the TAPI docs on the functions and messages
I posted, first. Then, tell me what exactly you don't understand.

Gomathy, you are welcome.
Here is (simplified) code snippet (without error handling) that works in one
of my TSP:
RpcImpersonateClient(0);
HKEY hHKCUkeyBase = NULL;
RegOpenCurrentUser(KEY_QUERY_VALUE, &hHKCUkeyBase);
HKEY hHKCUkey = NULL;
RegOpenKeyEx(hHKCUkeyBase, "Software\\Gomathy\\TSP", 0, KEY_QUERY_VALUE,
&hHKCUkey);
// now you can RegQueryValueEx() as required
RegCloseKey(hHKCUkey);
RegCloseKey(hHKCUkeyBase);
RpcRevertToSelfEx(0);

Hi Andreas,
I tried calling RpcImpersonateClient(0), but it returns error 1725.
How can I solve this error? :(

Hi Andreas,
Is that possible to call RpcImpersonateClient(0) in Win XP PC?
I dont have any server client mechanism here. If I call the function
to which user will it get impersonated? I m trying to call this when I
start my communication thread. Is that the right place to call. I m
still getting the error 1725.
Thanks & Regards,
Gomathy |

Gomathy,
yes it is.
I've done this successfully in a TSP created with JulMar TSP++ V3 on XP/SP2.

Hi Matthias,
I am trying to send the LINE_CREATEDIALOGINSTANCE message
to the TAPI to handle the event.
I have some doubts in implementing this. My TSP has a UI dll, and I m
trying to use the same for this. The implementation of
TUISPI_providerConfig() contains the Dll call back to the
TSPI_providerGenericDialogData(). As per your explanation, the message
will call the TSPI_providerGenericDialogData() function. While
clicking on the configure button in control panel, the flow is like,
first TUISPI_providerConfig() and then TSPI_providerGenericDialogData
(). Is this the same order when I send this message?
Thanks & Regards,
Gomathy |

No. When you send LINE_CREATEDIALOGINSTANCE in your
TSP, then the
TUISPI_providerGenericDialog
function is called.
TUISPI_providerGenericDialogData
is a completely different thing. It's for exchanging data with the TSP.
