Including DLL's

This is a discussion on Including DLL's within the C++ Programming forums, part of the General Programming Boards category; I was wondering if there was any way to include a .DLL file WITHOUT having to have the .DLL file ...

    Including DLL's

    I was wondering if there was any way to include a .DLL file WITHOUT having to have the .DLL file in the same directory as the .EXE? Like, I want to have the .DLL inside of the .EXE so other users wont have to worry about having the .DLL on their computer to execute the .EXE. I hope I didnt confuse you. The LoadLibrary functions I found only work if the .DLL is in the same directory as the .EXE so please dont tell me how to load .DLLs with the LoadLibrary functions.

    Thanks for any help. It is much appreciated.

    I'm sorry, but this is the first time I've heard of "static linkage". Would you mind explaining to me how I would include .DLL in a .EXE with this?

    Now that's a good one. From what i recall DLL stands for Dynamic Link Library. I guess that says it all doesn't it? DLL's are supposed to be linked dynamically not statically. Usually for static linking the extension in windows is .lib

    How do I convert a .DLL to a .LIB and then how do I include a .LIB? The .DLL file is libmySQL.DLL. I'm sorry, but I'm not very experienced with C++.

    Thanks for the replies. Its appreciated.

    Have you tried to use the DLL with the import lib which is created from your compiling the DLL? You'll have to include your header file and import lib when you're linking all your objects. Finally, the DLL must be in the PATH or the same directory as the executable. This approach eliminates the need to use LoadLibrary.

    There's no way that i know of to convert a .DLL into a .LIB. Plus, is there any good reason for doing that? or are you just trying to hide the fact that you are using it?

    Thats what I'm trying to eliminate...

    I want to make a program where you only need a .EXE and nothing else. I dont want other people who use this program to have to hassel with the .DLL (hassel = keeping the .DLL in the same directory).

    Hmmm, that's no hassle, you will have to distribute the application won't you? Simply distribute the .DLL with it. Don't take me wrong but to me it just looks like you are trying to hide the fact that you are using that library, for some obscure reason.

    Some libraries come in both static and dynamic flavors so its not realy a stupid sugestion.

    I agree that including dlls in your distribution isn't a big deal, put them all in one zip file. Or you can use one of those freeware installers.

    I say this is something malicious, it's the only logical explanation(forgot how to spell lol)... having to copy a dll along with the virus everywhere would just be gay I guess... It's kindof obvious since he isn't going to be keeping the exe in the same directory and even if it was legit, just moving one more file wouldn't be a "hassle"

    well, i wouldn't go all that far as to state that, i was more thinking about some kind of licensing issues. For instance, if i'm not mistaken using a library under GPL can get a user in trouble if it's a comercial application and the the source code isn't freely available.

    As stated in the Gnu General Public License:
    For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights.

    AFAIK, there is no way create a program that eliminates the DLL unless you have the source code to the DLL. You can recompile the DLL source code into a static library and link this library with your app at compile time thus eliminating the need for a DLL. Bottom line is you need the static lib version of this DLL since I know of no way to convert a binary DLL into a static lib.

    It will lead to the same result, what i posted is not morally correct nor ethical, if it's even legal which i even think it's not.

    Cheers
