[ VC(Visual C++) ]-DLL系列(03_抓抓圖)
本篇分享抓抓圖DLL，有興趣的(C/P)同好，歡迎來http://filemarkets.com/file/jashliao/753c17ea/索取，因為我不會上傳檔案分享哈哈 ^ ^。
主要程式碼:
// DC2DC.cpp : Defines the initialization routines for the DLL.
//
#include "stdafx.h"
#include "DC2DC.h"
#include "DibSection.h"
#include
#ifdef _DEBUG
#definenew DEBUG_NEW
#undef THIS_FILE
staticchar THIS_FILE[] = __FILE__;
#endif
int n;
char str1[10];
//
// 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.
