Hi, I'm trying to debug an erratic crash bug in my code that involves URLMoniker.dll and Wininet.dll. I can't get any of the PDB files in the XP SP2 symbols download to work in VC6 and I cannot get URLMoniker.pdb and Wininet.pdb to load in VC7. Any help or advice on how to get this information while debugging would be appreciated. Thanks in advance. sample VC7 call stack: NTDLL.DLL!_KiFastSystemCallRet@0() NTDLL.DLL!_ZwWaitForSingleObject@12() + 0xc MSWSOCK.DLL!_SockWaitForSingleObject@16() + 0x3a MSWSOCK.DLL!_WSPSelect@24() + 0x324f WS2_32.DLL!_select@20() + 0xa7 wininet.dll!771d714f() urlmon.dll!7727a64e() NTDLL.DLL!_NtSetEventBoostPriority@4() + 0xc NTDLL.DLL!_RtlpUnWaitCriticalSection@4() + 0x22 NTDLL.DLL!_RtlLeaveCriticalSection@4() + 0x1d NTDLL.DLL!__LdrpInitialize@12() + 0x10e NTDLL.DLL!__LdrpInitialize@12() + 0x94 NTDLL.DLL!_NtContinue@8() + 0xc urlmon.dll!7727a64e() urlmon.dll!7727a668()
