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…
Automatic Snapshots runs as a background application monitors clipboard. Should a new image be copied there, the utility automatically writes the image into a file. The process does not require any user interaction and is completely automatic so that – per Mike Westen‘s request – user could quickly and easily create snapshots of a multitude…
A really long and annoying troubleshooting of a problem finally ended with a bug found in GetAdaptersInfo/GetAdaptersAddresses API. It may unexpectedly fail under the following conditions: 32-bit application 64-bit operating system or /3GB feature enabled on 32-bit operating system hosting process is linked with /LARGEADDRESSAWARE flag or has otherwise set it in binary header over…
EnumerateVcmCodecs uses ICOpen API to enuerate available codecs and prints out information obtained from enumeration. 32-bit and 64-bit versions respectively enumerate codecs available for the platform (lists may vary because the codecs are actually provided by different DLLs, built for respective platform). szName fccType: 0x63646976 (vidc), fccHandler 0x64697663 (cvid) dwFlags 0 dwVersion 0x0, dwVersionICM 0x104…
RasterizeFont utility takes a font on the input (such as Windows .TTF – True-Type Font) and paints individual characters into bitmaps. Utility output includes separate bitmap (.BMP) files for requested characters and C++ source code of the bimap arrays (this was included into microcontroller project). A configuration .INI file defines rasterizer parameters: [General] Width=48 Height=72…
LogicalProcessorInformation is a fronend GUI around GetLogicalProcessorInformation API and reveals CPU configuration of the system. If you are fine tuning stuff, you might want to know what sort of CPUs are powering the applications: how many? fully featured cores or HyperThreading technology? mutli-processor configuration and how exactly physical processors are distributed over affinity mask API…
Previous post on thread synchronization and context switches used number of thread context switches as one of the performance indicators. One might have hard times getting the number from operating system though. The only well documented access to amount of context switches seems to be accessing corresponding performance counters. Thread performance counter will list available…
