我想MDI从DLL里加载工具条。
计划如下：
1.在DLL里创建工具条



extern "C" _declspec(dllexport) BOOL FristToolBarAPI (HWND HParentWnd,HWND*  pHFunctionWnd,CBCGPToolBar*& pTool)

{

	AFX_MANAGE_STATE(AfxGetStaticModuleState());

	CWnd* m_parentwnd=CWnd::FromHandle(HParentWnd);



	m_wndToolBar   =   new   CBCGPToolBar;   

	if   (m_wndToolBar   !=   NULL)   

	{   

		//m_wndDialogBar->Create(IDD_ADD1DLG,m_parentwnd); 

		if (!m_wndToolBar->Create (m_parentwnd,

			WS_CHILD|WS_VISIBLE|CBRS_TOP|CBRS_TOOLTIPS|CBRS_FLYBY|

			CBRS_HIDE_INPLACE|CBRS_SIZE_DYNAMIC|

			CBRS_GRIPPER | CBRS_BORDER_3D, IDW_BAR1) ||

			!m_wndToolBar->LoadToolBar(IDR_TOOLBAR1, 0, 0, FALSE, 0, 0, IDB_BITMAP1))

		{

			TRACE0("Failed to create toolbar\n");

			return -1;      // fail to create

		}

		*pHFunctionWnd=m_wndToolBar->m_hWnd; 

		pTool=m_wndToolBar;

	}

	return TRUE;

}

2.在CChildFrame中OnCreate()调用



hToolDll=LoadLibrary(_T("AddBCGDlll.dll"));

	if (hToolDll==NULL)

	{

		AfxMessageBox("LoadDllError");

	}

	else

	{

		ShowPARChildBar * pf1;

		pf1=(ShowPARChildBar *)::GetProcAddress(hToolDll,_T("FristToolBarAPI"));

		if (pf1==NULL)

		{

			AfxMessageBox("LoadProcError");

			FreeLibrary(hToolDll);

			hToolDll=NULL;

		}

		else

		{

			(*pf1)(m_hWnd,&pTool,m_ToolBar1);

			CString strMDIToolbarTitle;

			strMDIToolbarTitle.LoadString(IDW_DIALOGBAR1);

			m_ToolBar1->SetWindowText(strMDIToolbarTitle);

			m_ToolBar1->EnableDocking(CBRS_ALIGN_ANY);

			EnableDocking(CBRS_ALIGN_ANY);					                   DockControlBar (m_ToolBar1, AFX_IDW_DOCKBAR_BOTTOM); //到此句出错



		}

	}

DockControlBar (m_ToolBar1, AFX_IDW_DOCKBAR_BOTTOM); //到此句出错
出错，注释掉此句，工具条不显示，为什么呢？大牛帮帮忙啊？

我把工具条创建放在CChildFrame的OnCreate()正常。放在DLL里调用，到DockControlBar(m_ToolBar1, AFX_IDW_DOCKBAR_BOTTOM); 就出错。

C#中加载dll的问题最近在做C#上进行H264解码的网络摄像头，通过各种折腾，还是没法解决，无奈之下只好使用在C#下加载ffmpeg的动态库进行，在加载的时候说不遇到问题那是不可能的。下面就我遇到的问题和解决方案进行发表： 1.加载方法很多人都想着通过右键引用的方法进行dll的加载，当然那是简便的方法，不过对于用C++编译的动态库貌似这方法行不通，往往会提示“未能添加XXX.dll的引用。请阅读详情

你可以参考一下BCG的多语言切换的DLL

1.应是扩展MFC DLL吧,你如何创建的? DLLMain()中是如何写的?
2.对于模块,线程等state可参考李进久<MFC深入浅出> (注:非侯老师<深入浅出MFC>)

你先试一下非BCG的加载成不成
BCG很多东西加不进去

Sorry,没用过BCG。

AfxSetResourceHandle，把你的handle设置为dll的，工具条处理后再设置成应用程序的

该ToorBar没有GetSafeHandle()，
我直接在DLL中传了一个HWND： *pHFunctionWnd=m_wndToolBar->m_hWnd;
这样可以吗？

个人理解:它们分属不同的module. Window Handle Map 是module相关的.

你可以试试:
(*pf1)(m_hWnd,&pTool,m_ToolBar1);
CString strMDIToolbarTitle;
strMDIToolbarTitle.LoadString(IDW_DIALOGBAR1);
m_ToolBar1->Set……

还是不行
