VC++调用DLL的演示示例代码，供测试调用的CommonDll.dll已经放在测试源码的根目录下，你下载源码后可运行InvokeDll.dsw编译项目源码，将编译生成在Bin目录中的InvokeDll.exe拷贝至根目录下，双击运行，可看到程序调用DLL后，将输出一条消息，完美演示在VC++环境下如何调用一个已知的DLL实现某些特定功能。-VC++ DLL called demo code for the test call CommonDll.dll has been placed under the test source root directory, you can download the source code after running InvokeDll.dsw compile the project source code, the compiler generates InvokeDll.exe copy in the Bin directory to the root directory, double click to run, you can see the program calls DLL, will output a message perfectly demonstrated in VC++ environment how to call a known DLL achieve certain specific functions.
