How to get my own version?
in [Visual C]
|
From: broznoober on 7 May 2008 12:04 I have a DLL, built using VC6, and I want to programatically get its version number. I have searched the web for how to do this, and have found a bunch of pages saying to use GetFileVersionInfoSize, GetFileVersionInfo, and VerQueryValue. However, all of them seem to be written from the point of view of getting the version of *another* DLL. I want to get the version of a DLL from within that DLL itself. Is there an easier way to do this (e.g. something akin to VB6's App.Major and so forth), or do I have to go the GetFileVersionInfoSize / GetFileVersionInfo / VerQueryValue route? In particular, GetFileVersionInfo and ...Size require the pathname of the DLL in question. So do I seriously have to determine my own pathname in order to get my own version information? Assuming that I really do have to use that stuff, is there an easy way to get the pathname of a DLL from within the DLL itself? Thanks in advance for any help.

Use VirtualQuery, passing the address of something (e.g. a function) declared in your DLL as the 'lpAddress' parameter. After the call, the BaseAddress field of the MEMORY_BASIC_INFORMATION structure that you supplied will be the HMODULE of your DLL. Use GetModuleFileName, passing the HMODULE obtained above to get the full path to your DLL. -cd

GetModuleFileName using HINSTANCE handle passed to your DllMain (HINSTANCE and HMODULE are interchangeable). -- With best wishes, Igor Tandetnik With sufficient thrust, pigs fly just fine. However, this is not necessarily a good idea. It is hard to be sure where they are going to land, and it could be dangerous sitting under them as they fly overhead. -- RFC 1925

Including the header in your .cpp lets get you the version number without having to access the dll/exe e.g. version.h -------------- #define FVERS 2,0,0,1 + the other version strings like PRODUCTVERSION ..rc2 ----- #include "version.h" VS_VERSION_INFO VERSIONINFO FILEVERSION FVERS [...] your .cpp file -------------------- #include "version.h" hth/Anders. -- A: People bitching about top-posting > Q: What's the most annoying thing on USENET?
