Instead of defining the whole path, you may also just give the file name. | |||
<pre> | |||
var lib = ctypes.open("user32.dll"); | |||
</pre> | |||
Or even without the extension. | |||
<pre> | |||
var lib = ctypes.open("user32"); | |||
</pre> | |||
If the full path is not given, Windows uses the following search order to locate the DLL: | |||
#The current directory of the task that is using the DLL. | |||
#The \WINNT directory. | |||
#The \WINNT\SYSTEM directory. | |||
#The \WINNT\SYSTEM32 directory. | |||
#The directory of the executable for the task that is using the DLL. | |||
#A directory listed in the PATH environment variable. | |||
