从dllhost.exe中运行的inproc com dll生成dmp文件

Question

I am writing an inproc com dll that runs in the dllhost.exe surrogate, but I see an issue debugging it.

in exe's that I've written, I have a top level exception handler that creates a .dmp file i can load in windbg and then crashes, and I'm unsure of how to do this from dllhost. Is there another way to generate stack dumps from dllhost.exe on a crash? i've seen this page (http://support.microsoft.com/kb/910904), but it seems to involve the component services program. Is there some registry setting for this? Because it's something that will be installed on other computers.

Thanks

Rather than having the process dump itself, you can set up a just in time debugger to run when the process crashes. For older versions of Windows, Dr.Watson is a good one that can automatically generate dumps for crashing applications: http://en.wikipedia.org/wiki/Dr. Watson (debugger) I believe Windows Vista and later versions have replaced Dr.Watson with Windows Error Reporting ( http://support.microsoft.com/kb/931673 )

A simpler tool to use is Sysinternals procdump (use the -e option to dump on unhandled exceptions): http://technet.microsoft.com/en-us/sysinternals/dd996900
