DLL中导出对话框

DLL中导出对话框

建立Win32工程-->DLL->MFC的支持

加入一个对话框，增加对应类

正常导出一个函数，如下

DLL5_API int fnDll5(void) { AFX_MANAGE_STATE(AfxGetStaticModuleState()); // 这句很关键 CDllDlg5 dlg; dlg.DoModal(); return 0; }  

MSDN说明：

The AFX_MODULE_STATE structure contains global data for the module, that is, the portion of the module state that is pushed or popped. 

By default, MFC uses the resource handle of the main application to load the resource template. If you have an exported function in a DLL, such as one that launches a dialog box in the DLL, this template is actually stored in the DLL module. You need to switch the module state for the correct handle to be used. You can do this by adding the following code to the beginning of the function:

Visual C++  Copy Code 

AFX_MANAGE_STATE(AfxGetStaticModuleState( )); 

This swaps the current module state with the state returned from AfxGetStaticModuleState until the end of the current scope.
