Register a DLL
in [Win32 Kernel]
|
From: Fabio Sobral on 1 Jul 2008 14:41 Hi. I'm working on a dll to be used by a third party program, and my dll makes use of general purpose functions from a second dll also created by me. I thought the program would work fine if both dlls were on the same folder, but it only works if my second dll is placed inside the Windows/System32 folder. I'd like to know if there's a way to register the path to this second dll so it can be correctly loaded. Thanks, Fabio.
From: Kerem G�mr�kc� on 1 Jul 2008 20:38 Hi Fabio, use depends or a debugger to get the loading paths/accesses of all libraries in you application: http://www.dependencywalker.com/ Do a profilling on your application. See depends help on "profilling" for more info,... It would be also very usefull to tell us "what" exactly is not working and what error codes do you get when it fails, whatever fails,...

The DLL search algorithm is well-defined: http://msdn.microsoft.com/en-us/library/7d83bc18.aspx If the app loads the first DLL by name only, then it should be able to find the second in the same directory. But if the app loading the first DLL by using a full path, then that path will not be in the search. -- Tim Roberts, timr(a)probo.com Providenza & Boekelheide, Inc.

If the 3rd party program loads your library explicitly, then it would be worth investigating using LoadLibraryEx with the LOAD_WITH_ALTERED_SEARCH_PATH flag. Regards, Roger.
