You should be able to create a Console Application (Win32) and to change the output type to a dll (Library) in the settings of the project. You should get the WinSDK though as it comes with a DLL template that gives you a better start than the Console Application template and it comes with all the libraries and headers you will need.

Ok now I get it!
Thanks to all of you for your help!

Now I have the problem that I'm too stupid to get the sampledll working (with VC). I've linked the adll.lib and copied all files (adll.h, afuncs.h, atypes.h, avars.h, adll.lib, SampleDll.cpp) into my folder. But when I compile it it says: "fatal error C1010: Unerwartetes Dateiende während der Suche nach dem vorkompilierten Header. Haben Sie möglicherweise vergessen, im Quellcode "#include "stdafx.h"" einzufügen?"
In English: "fatal error C1010: Do you forgot to include "#include "stdafx.h"" into the sourcecode?"

-> I wrote "#include "stdafx.h"" and another error appeared: "Datei (vorkompilierte Headerdatei) kann nicht geöffnet werden: "Debug\test.pch": No such file or directory"
In Enlish: "File (precompiled headerfile) can't get opened: "Debug\test.pch": No such file or directory"

What am I doing wrong? Has anyone a running example?

when im creating a dll i follow this steps, and dont get any errors:

open vc++ 2008 xpress-> click project(next to create)->select win32 from left->select win32 project->Enter a name->ok->click next->chose dll->Click finish

then add other headers/spurces to the project

Ok, I did it like you did it.
What headers do you include and how? Do you only write the includes into the source and copy the files into your folder or do you also include them into your project (left side, project manager)?
And how do you include the adll.lib? Is it correct if I do it like this: [project]->[settings]->[Linker]->[Input]->and then into the first line: "adll.lib"? And of course I copied the adll.lib into the folder.

You should set the project settings to not use precompiled headers.

The following settings work fine for me, but you might want to play around with some of these.

Now try to compile the sample.cpp file. You should find it in the debug-subfolder.
Copy it into your acknex plugin directory.

Thanks for this detailed description, now this thing (compiling a gsdll) works.

I started now to recompile my enet.dll with VC++, but it seems like I don't include the enet things correct. I did it like they said on the webside (enet.bespin.org/Installation.html): I opened the enet project and compiled it -> I got a enet.lib file. I copied this file into the lib folder of VC++, linked it in my dll-project and also linked the ws2_32.lib. But now I have the problem, that when I call one of the enet functions (like enet_initialize) i get an error: "enet_initialize can't found".
Now my question: If I include a static libary, do I also need to include the headers which I compiled into the lib in my dll-project? Does anybody have experiance with using enet in VC++?
And the gag is, that with Dev-C++ it worked after doing that (and some help of nfs42). But in general I did it like that, but in VC++ it don't works like this...

Thanks!

Sure, you have to include the headers (Actually in most cases only the project-name.h, e.g. enet.h).

Ok i included the enet.h, but now I get a lot of new errors: "enet.lib(win32.obj) : error LNK2019: Verweis auf nicht aufgelöstes externes Symbol "__imp__timeBeginPeriod@4" in Funktion "_enet_initialize"."
English: "enet.lib(win32.obj): error LNK2019: reference to a not decomposed extern symbol "__imp__timeBeginPeriod@4" in function "_enet_initialize"."

Maybe I did something wrong at compiling the enet.lib?

Dark_Samurai

Seems that you forgot to include winmm.lib
