A basic task in thread synchronization is putting something on one thread and getting it out on another thread for further processing. Two or more threads of execution are accessing certain data, and in order to keep data consistent and solid the access is split into atomic operations which are only allowed for one thread…
If you share concept (as I do) that every build should have a unique file version stamp in it, for a simple purpose – at least – to distinguish between different version of the same binary, then a helpful tool of automatic incrementing fourth number in FILEVERSION’s file version is something you cannot live without.…
If you were adding and removing ActiveX controls programmatically with ATL, you might have noticed a nasty memory leak after final release of the control. Control added, removed and a leaky block is left om heap. Tracking simple memory leaks is not a rocket science with Microsoft C++ runtime, by adding _CRTDBG_MAP_ALLOC define, as described…
Windows Vista added new synchronization API, Slim Reader/Writer (SRW) Locks, which is a powerful alternative to critical sections. The detailed description is, as always on MSDN, and what makes it really cool is simple: unlike critical sections, SRW Locks provide reader and writer access synchronization making it possible for 2 and more reader to not…
Because Microsoft C++ Runtime library is distributed as a side-by-side assembly, GetModuleHandle and LoadLibrary is no longer available to locate the library within the process. Both API calls would return NULL handle. HMODULE hModule = GetModuleHandle(_T(“msvcr90.dll”)); HMODULE hModule = LoadLibrary(_T(“msvcr90.dll”)); Still, how to locate the modules in order to, for example, be able to check…
Before attributed ATL was deprecated, it was a convenient way to access databases using attributed classes on top of OLEDB Consumer Templates. Does not it look nice? [ db_command(“SELECT ServerData FROM Server WHERE Server = ?”) ] class CGetServerData { public: [ db_param(1) ] LONG m_nServer; [ db_column(1, length = “m_nDataLength”) ] ISequentialStream* m_pDataStream; DBLENGTH…
ProcessSnapshot is a utility to take a snapshot of process call stacks, and the snapshot taken is written into a human friendly text file. Additionally to this, the utility has been given a capability to create process minidump files, on user request. The minidump files can be used with debugger to analyze the context of…
