svchost.exe: Unloaded...

[Michael]

Hi,
I have problem with svchost (ro maybe with something else) I’m trying to
make simple TSP fiew days ago in debug window I was receiving such info:

[…]
TSPI_providerUIIdentify rc=0x0, lpszUIDLLName=0x1817204 "MyTSPUI.DLL"
TSPI_lineNegotiateTSPIVersion dwDeviceID=0xffffffff,
dwLoVersion=0x10003, dwHiVersion=0x30001, lpdwTSPIVersion=0x1815c70
TSPI_lineNegotiateTSPIVersion rc=0x0, lpdwTSPIVersion=0x30000
TSPI_providerEnumDevices dwPermanentProviderID=0x68, lpdwNumLines=0x298f3d4,
[...]

And now I’m getting :
'svchost.exe': Unloaded 'C:\WINDOWS\system32\MyTSP.tsp'

I compiled earlier version when it was ok, but now the same hapening.
I’m guessing that is something with system. First I was receiving
svchost errors – Visual Studio debugger was appearing all the time, then
after Windows reinstaling when I’m oppening new folder some Adobe
instalation wants start – Norton Antivirus found nothing. Can I avoid
disk system formating?

Best Regards,
Michael

Where exactly do you get this from?

Issues within TAPISRV are almost always caused by one of the TSPs itself.
Did you try installing your TSP on another PC (maybe a virtual PC)?
How exactly do you install your TSP?

Andreas, thank You for your response.

I’m Using VS 2005 with Debug Tapisrv Add In. I made simple TSP with
Julmar’s wizard, added fiew debug info in service provider and device
constructor, and in VS debugger was receiving (part which was saved):

-- service provider constructor --
TSPI_providerUIIdentify lpszUIDLLName=0x1817204
TSPI_providerUIIdentify rc=0x0, lpszUIDLLName=0x1817204 "SipTSP9UI.DLL"

TSPI_providerInit rc=0x0, lpdwTSPIOptions=0x1815c6c
IntervalTimerThread(0x1a0) starting
LibraryTimerThread(0x65c) starting


And I think I haven’t made others changes after that besides added to
every class debug info like: _TSP_DTRACE(" -- device init -- ");

And after that I’m receiving:

'svchost.exe': Loaded 'C:\WINDOWS\system32\MyTSP.tsp', Symbols loaded.

'svchost.exe': Unloaded 'C:\WINDOWS\system32\MyTSP.tsp'

To install TSP I’m simply putting MyTSP.tsp and MyTSPUI.dll files to
Windows/system32 folder. I tried to instal my TSP on other PC (without
VS2005 but with DBWin32) and looks like the same problem occurring.

Your TSP is telling TAPISRV that it supports 0 line and 0 phone devices.
So it is exposing no device at all.

Do you get the same result if you report at least one device?

Hi,

Sorry for delay of my response but lately I have many things on my head.
I think I had some viruses in my system or other bad stuff, so I recover
it to safety state. Now it looks ok. But still I have problem with my
TSP. I see that I don’t have set line. What I want is to set a line and,
I think, have MakeCall feature to send SIP message: INVITE, but I’ve
got stuck in code.

In debug trace I have: (entries like : "-- device init –" are my
indiwidual for marking whitch class is running):

dwPermanentLineID = 0x0

Michael,
You need to generate a unique dwPermanentLineID.
Usually the upper WORD of the DWORD is filled with dwPermanentProviderID from
TSPI_providerInit(),
i.e. dwPermanentLineID = (dwPermanentProviderID << 16) + (0x0000FFFF &
dwSomething);

Post by Michael
dwAddressModes = 0x1 (ADDRESSID)
dwNumAddresses = 0x0

You need to support at least one address, i.e. dwNumAddresses=1;

Post by Michael
dwMediaModes = 0x0

You need to support at least one media mode, e.g.
LINEMEDIAMODE_INTERACTIVEVOICE

Post by Michael

Post by Michael
TSPI_lineClose hdLine=0x1a26f50

I guess TAPISRV doesn't like either your TSP's line device having no address
in TSPI_lineGetDevCaps() / TSPI_lineGetNumAddressIDs(), and/or supporting no
media mode in TSPI_lineGetDevCaps(), and/or returning LINEERR_INVALDEVICECLASS
from TSPI_lineGetID().
You need to implement TSPI_lineGetAddressCaps() too, if you haven't already.

Andreas, big thanks for Your response.

I was debugging my TSP according Yours advices, and finally found
problem. I was using separated UI in which I didn't include any line and
address handling and TSP wanted use that information. Now I've made
simple TSP without separated UI and I can chose my line in TAPI
applications.
That was painful but didactic process for me ;-)

'svchost.exe': Unloaded 'C:\WINDOWS\system32\MyTSP.tsp'

hi Michael,

I have read this information as well. I don't think that is a problem, IMO,
the svchost can unload your tsp if it is not used, and
if you want use your TSP, it will be loaded again. It only matters if your
TSP is working or not.

regards,

Sheng
