Solution from: http://blog.sina.com.cn/s/blog_6a2236590100xbgl.html

1 Static Call Lib
Project | Setting

Link Tab Library Modules office
Add "XXX.lib"
Then include "XXX.h"
Put XXX.lib (inbound file), XXX.DLL (Dynamic library file)
XXX.h (header file)
Put them all in the project directory.
Method Two:
pragma commet (lib, "*****.lib")


2 Dynamic Call DLL
Pass
LoadLibrary
GetProcAddress

FreeLibrary implementation.

Cause: The project supports only Unicode characters

Workaround:

1, project properties, configuration Properties--General---> Character set----> use multibyte Character set 2, that is, the wide character, so the following line of code, should be compiled with errors Hinst=loadlibrary ("InTheHand.Net.Personal.dll"); That is Cannot convert parameter 1 from ' char [+] ' to ' const unsignedshort * ' Landlord will change the code to: Hinst=loadlibrary (L "InTheHand.Net.Personal.dll"); Or Hinst=loadlibrary (_t ("InTheHand.Net.Personal.dll")); Give it a try 。
