One annoying thing existing for a long time is an internal _com_error exception in Direct3D shader cache, coming from D3DSCache.dll during execution of innocent API calls like D3D11CreateDevice. Also related storage location for the cache files is %LOCALAPPDATA%\D3DSCache, one can try deleting it completely in the case annoying issue persists. Many of us can afford…
Moving on with LogProcessExceptions tool which externally monitors (debugs, to be more specific) an application of interest and captures its exceptions writing minidump files for further analysis. This updates adds two features: Ability to filter out the exceptions of interest An email notification on exception, with or without minidump file Filter A new property page…
One of the nasty issues with LogProcessExceptions utility was that it was unable to attach to service processes and track them to catch their exceptions. The actual problem was that the processes were not listed in first place, so there was nothing to attach to. Access and security requirements necessary for a process to debug…

LogProcessExceptions utility implements a very basic debugger which attaches (see DebugActiveProcess on MSDN) to a running process and monitors its exceptions. Once exception takes place the utility creates a minidump file for the process (see MiniDumpWriteDump on MSDN) so that exception condition could be investigated off-site using debugger. If you throw C++ exceptions in your…
While playing around with a camera DirectShow video source filter, AMCap, which is widely used sample and which I believed to be very stable, started crashing in an inner call CDeviceMoniker::IsEqual: devenum.dll!CDeviceMoniker::IsEqual() + 0x13 bytes > AmCap.exe!ChooseDevices(IMoniker * pmVideo=0x003e9a38, IMoniker * pmAudio=0x00000000) Line 2672 + 0x2a bytes C++ AmCap.exe!ChooseDevices(wchar_t * szVideo=0x0013f5b8, wchar_t * szAudio=0x0013edb0) Line…
