c - Is it possible to link against a Windows .dll+.lib file combination using gcc/g++ under Cygwin? -


i know how link against libraries in unix-ish contexts: if i'm working .a or .so files, specify root search directory -l/my/path/to/lib/ , libmylib add -lmylib.

but if have

  • a .dll (e.g. in windows\system32 directory)?
  • a .dll (in windows\system32) , .lib (someplace else)?

these dlls other party; don't have access sources - have access corresponding include files, against manage compile.

if can link against .lib in cygwin or mingw, can (indirectly) link against dll.

in msvc world, not unusual create import library along dll. static library (.lib) loads dll , wraps interface of dll. call wrapper functions in (static) import library , let import library dll-related things.

  • for windows api, there import libraries in windowssdk.
  • for own msvc dlls, msvc can automatically generate import libraries when build dll.
  • for third party dll, can build static wrapper library based on corresponding header files.

linking against .lib file in cygwin or mingw possible. example:

g++ -o myprg myprg.o -lshlwapi

this links against shlwapi.lib. (the library must in local directory or in library path of linker.)

linking against import libraries of dlls works same way.

note 1: keep in mind different abis , name mangeling. however, calling plain c functions in dll or lib files work in cases.

note 2: keep in mind g++ requires libraries specified in correct order.

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
