WTL环境优化:

修改AppWiz文件夹下setup90x.js 。把第152行 fileDest.WriteLine("Param=\"VC_EXPRESS = 1\""); 这句删除。

WTL向导认为如果是Express版本的VC一定是和psdk2003是的atl配合的，具体和atlthunk相关。如果不删除这句，用向导生成程序是运行不了的

然后在AppWiz\Files\Templates\1033文件夹找到stdafx.h 在32行添加#pragma comment(lib,”atlthunk.lib”)。这样用向导生成的程序就不会有链接错误了。

工程名为WTLTest。

选择Generate .cpp Files是为了产生cpp文件，这样更符合我们的习惯，不然只有.h文件产生.

调试过程后得知，WTL的调用如下：

1、_tWinMain入口

int WINAPI _tWinMain(HINSTANCE hInstance, HINSTANCE /*hPrevInstance*/, LPTSTR lpstrCmdLine, int nCmdShow){ HRESULT hRes = ::CoInitialize(NULL);// If you are running on NT 4.0 or higher you can use the following call instead to // make the EXE free threaded. This means that calls come in on a random RPC thread.// HRESULT hRes = ::CoInitializeEx(NULL, COINIT_MULTITHREADED); ATLASSERT(SUCCEEDED(hRes));
 // this resolves ATL window thunking problem when Microsoft Layer for Unicode (MSLU) is used ::DefWindowProc(NULL, 0, 0, 0L);
 AtlInitCommonControls(ICC_BAR_CLASSES); // add flags to support other controls
 hRes = _Module.Init(NULL, hInstance);  // 初始化 ATLASSERT(SUCCEEDED(hRes));
 int nRet = Run(lpstrCmdLine, nCmdShow);
 _Module.Term();                        // 结束 ::CoUninitialize();
 return nRet;}
2、采用ATL初始化模块.

CAppModule _Module；

_Module.Init(

// Overrides of CComModule::Init and TermHRESULT Init(ATL::_ATL_OBJMAP_ENTRY* pObjMap, HINSTANCE hInstance, const GUID* pLibID = NULL){HRESULT hRet = CComModule::Init(pObjMap, hInstance, pLibID);if(FAILED(hRet))return hRet;m_dwMainThreadID = ::GetCurrentThreadId();typedef ATL::CSimpleMap<DWORD, CMessageLoop*>   _mapClass;m_pMsgLoopMap = NULL;ATLTRY(m_pMsgLoopMap = new _mapClass);if(m_pMsgLoopMap == NULL)return E_OUTOFMEMORY;m_pSettingChangeNotify = NULL;return hRet;}

结束时是_Module.Term();

void Term(){TermSettingChangeNotify();delete m_pMsgLoopMap;CComModule::Term();}

3、创建ATL窗口

int Run(LPTSTR /*lpstrCmdLine*/ = NULL, int nCmdShow = SW_SHOWDEFAULT){CMessageLoop theLoop;_Module.AddMessageLoop(&theLoop);CMainDlg dlgMain;if(dlgMain.Create(NULL) == NULL){ATLTRACE(_T("Main dialog creation failed!\n"));return 0;}dlgMain.ShowWindow(nCmdShow);int nRet = theLoop.Run();_Module.RemoveMessageLoop();return nRet;}
