[ VC(Visual C++) ]-DLL系列(01_DLL共享記憶體)
本篇要分享DLL共享記憶體，有興趣的(C/P)同好，歡迎來http://filemarkets.com/file/jashliao/d3f5c30a/索取，因為我不會上傳檔案分享 哈哈 ^ ^。
主要程式碼 :
// mfcdll.cpp : Defines the initialization routines for the DLL.
//
#include "stdafx.h"
#include "mfcdll.h"
////////////////////////////////////////////////
#pragma data_seg(".SHARDAT")
static HWND ghWndMain = 0;
static HHOOK ghKeyHook = NULL ;
#pragma data_seg()
HINSTANCE ghInstance = 0;
HOOKPROC glpfnHookProc = 0;
/////////////////////////////////////////////////
#ifdef _DEBUG
#definenew DEBUG_NEW
#undef THIS_FILE
staticchar 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.
//
/////////////////////////////////////////////////////////////////////////////
// CMfcdllApp
BEGIN_MESSAGE_MAP(CMfcdllApp, CWinApp)
//{{AFX_MSG_MAP(CMfcdllApp)
// NOTE - the ClassWizard will add and remove mapping macros here.
// DO NOT EDIT what you see in these blocks of generated code!
//}}AFX_MSG_MAP
END_MESSAGE_MAP()
/////////////////////////////////////////////////////////////////////////////
// CMfcdllApp construction
CMfcdllApp::CMfcdllApp()
{
// TODO: add construction code here,
// Place all significant initialization in InitInstance
}
/////////////////////////////////////////////////////////////////////////////
// The one and only CMfcdllApp object
int EXPORTED_DLL_FUNCTION jashGetValue ()
{
return lngtestValue;
}
void EXPORTED_DLL_FUNCTION jashSetValue (int a)
{
lngtestValue=a;
}
int EXPORTED_DLL_FUNCTION KbdHookProc (int a, int b)
{
int r;
r=a+b;
return (r);
}
CMfcdllApp theApp;
BOOL CMfcdllApp::InitInstance()
{
// TODO: Add your specialized code here and/or call the base class
AFX_MANAGE_STATE(AfxGetStaticModuleState());
ghInstance = AfxGetInstanceHandle();
return CWinApp::InitInstance();
}
int CMfcdllApp::ExitInstance()
{
// TODO: Add your specialized code here and/or call the base class
return CWinApp::ExitInstance();
}
