where's wrong???

Hi,

I am a beginner and download CWBButton Control to apply it in my own program,
but the following things happened:

MyExamDoc.obj : error LNK2001: unresolved external symbol
"public: virtual __thiscall CWBButton::~CWBButton(void)" (??1CWBButton@@UAE@XZ)

PenDialog.obj : error LNK2001: unresolved external symbol
"public: virtual __thiscall CWBButton::~CWBButton(void)" (??1CWBButton@@UAE@XZ)

PenDialog.obj : error LNK2001: unresolved external symbol
"public: __thiscall CWBButton::CWBButton(void)" (??0CWBButton@@QAE@XZ)

PenDialog.obj : error LNK2001: unresolved external symbol
"public: bool __thiscall CWBButton::LoadBitmaps(unsigned int,int,int,int,int,int)"
(?LoadBitmaps@CWBButton@@QAE_NIHHHHH@Z)

Debug/MyExam.exe : fatal error LNK1120: 3 unresolved externals

Can you tell me what cause them? Thank you! I use visual c++6.0

best regards
eaglee

是不是没有
#include 头文件???

[eaglee]

包括了呀？是不是在PenDialog.h 中#include "WBButton.h"?

[eggplant]

首先，要在WBButton.cpp中#include "WBButton.h"
然后，在PenDialog.cpp或.h 和MyExamDoc.cpp或.h，包含WBButton.h才行。

顺便在MyExamDoc.cpp中
#include "WBButton.h"

用到的地方都要能见到声明才行呢，，，嘿嘿

试过了，还是不行，另外，我是把 WBButton.h and WBButton.cpp 直接放到我的工程目录
下，这样做有问题吗？

你需要把WBButton.lib加入项目中。菜单project\settings,link,页中object/library modules中填入WBButton.lib,并把WBButton.lib和WBButton.dll拷入项目所在目录。
