我幫你做了這個簡易的鉤子，基本實現了你的功能?
這個是dll代碼
#include?"stdafx.h"
#include?"GetMouseMessage.h"
#ifdef?_DEBUG
#define?new?DEBUG_NEW
#undef?THIS_FILE
static?char?THIS_FILE[]?=?__FILE__;
#endif
//
//??Note!
//
//????If?this?DLL?is?dynamically?linked?against?the?MFC
//????DLLs,?any?functions?exported?from?this?DLL?which
//????call?into?MFC?must?have?the?AFX_MANAGE_STATE?macro
//????added?at?the?very?beginning?of?the?function.
//
//????For?example:
//
//????extern?"C"?BOOL?PASCAL?EXPORT?ExportedFunction()
//????{
//??????AFX_MANAGE_STATE(AfxGetStaticModuleState());
//??????//?normal?function?body?here
//????}
//
//????It?is?very?important?that?this?macro?appear?in?each
//????function,?prior?to?any?calls?into?MFC.??This?means?that
//????it?must?appear?as?the?first?statement?within?the?
//????function,?even?before?any?object?variable?declarations
//????as?their?constructors?may?generate?calls?into?the?MFC
//????DLL.
//
//????Please?see?MFC?Technical?Notes?33?and?58?for?additional
//????details.

????}
??}

}
//?安裝鉤子
extern?"C"?_declspec(dllexport)?void?SetHook(void)
{
??g_hook?=?SetWindowsHookEx(
????????????????WH_MOUSE_LL,?????????//?type?of?hook?to?install

??if?(g_hook?==?NULL)
??{

??}
??return?;
}
//?卸載鉤子
extern?"C"?_declspec(dllexport)?void?EndHook(void)
{
??if?(g_hook?!=?NULL)
????UnhookWindowsHookEx(g_hook);
}
注意，您必須在stdAfx.h中加上
#define?_WIN32_WINNT??0x0500
因為在winuser.h中只有定義了上面的才定義的WH_MOUSE_LL
然后您在另外建一對話框工程
加一個按鈕
在工程目錄下加進上面的GetMouseMessage.dll和GetMouseMessage.lib
在按鈕事件中寫
extern?"C"?_declspec(dllimport)?void?SetHook(void);
extern?"C"?_declspec(dllimport)?void?EndHook(void);
void?CTestGetMessageDlg::OnButton1()?
{
??//?TODO:?Add?your?control?notification?handler?code?here
??SetHook();
}
我試過
完全ok
