DLL header hiding question...

[JulesChrono]

:(( Hi, I was wondering if I am given a DLL with a set of header files to use (of which i don't have the source to). Is there a way to create a new DLL (with a new set of header files) that uses the functions of the old DLL without giving access to the old header files? Is this possible? In short, I want to create a new wrapper DLL with a new set of header files without sharing information of the old headers. I've been looking all over the web and couldn't find anything. Thanks! RCJ

Hi There I don't know if I have understand your question correct, but my answer is, to what I have undertand :-) : I would create a new header file, called DllInterface.h which will declare all the functions/methods that you want to export. Afterwards, create a new class called CreatorDll, which will implement all the original methods. In this class, in your cpp file, only include all the header files you want to hide. In the corresponding header file include the Interface file. If you have some classes which you want to offer users of the dll, make creator functions in your creator class, which returns with instances of the corresponding classes. Then the places where you want to use the dll, only include the headerfile for the creator. This is the way I do, when I want to export some methods of class, which perhaps uses a lot of classes. I hope this gives you an idea, or maybe can help you in the wanted direction. Best regards, Søren Madsen Denmark

I think it can been make: 1.We create a dll project whitch the new header file. 2.at our dll project,we relocate the function to the old function in the old dll,use Loadlibrary("old.dll"); and GetProcAddress(...) can do it. 3.builder our dll project,so we get a new dll. :)
