Hello,
I have a dll registered to use virtual channel in mstsc
(HKEY_CURRENT_USER\Software\Microsoft\Terminal Server Client\Default\Addins),
before mstsc released with vista sp1 all works fine, but with the latest
whenever I click on connect in mstsc I will get an access violation.
First-chance exception at 0x6beab2f5 in mstsc.exe: 0xC0000005: Access
violation reading location 0x00000000
Tried to recompile my dll, doing nothing, just returning, and the crash
append too.
If I unregister the dll all works.
Has something related to virtual channel implementation changed? I checked
in many places but I have found nothing.
In the debug session I see following:
1. The sentence:
uRet = gpEntryPoints->pVirtualChannelInit( (LPVOID *)&gphChannel,
(PCHANNEL_DEF)&cd,
1,VIRTUAL_CHANNEL_VERSION_WIN2000,(PCHANNEL_INIT_EVENT_FN)VirtualChannelInitEventProc );
RETURNS uRet == 0 OK
2. Next inside the VirtualChannelInitEventProc, the sentence:
case CHANNEL_EVENT_CONNECTED:
{
if ( OUTPUT_DEBUG_INFO == 1 )
{
OutputDebugString( _T("CHANNEL_EVENT_CONNECTED\n") );
}
// open channel
ui = gpEntryPoints->pVirtualChannelOpen( gphChannel,
&gdwOpenChannel, CHANNELNAME,
(PCHANNEL_OPEN_EVENT_FN)VirtualChannelOpenEvent );
if ( ui == CHANNEL_RC_OK )
{
}
Returns ui == 0 OK, but the call-back function VirtualChannelOpenEvent never
is called and when exit from VirtualChannelInitEventProc, then following
exception is thrown:
First-chance exception at 0x6beab2f5 in mstsc.exe: 0xC0000005: Access
violation reading location 0x00000000.
The error in Event Viewer is following:
