MAPGIS67二次开发学习笔记1. 问题：文件-新建工程，文件-打开工程，实现代码处于DOC下，只是调用了VC的函数OnFileNew()和OnFileOpen()，如何实现打开mapgis工程的呢？ 答案：实现这个的具体操作在string table里面，只需修改参数即可，函数的话用VC的API函数即可。 2. 问题：如何控制一步一步打开程序界面。 答案：主资源文件CPP，初始化组件库，初始化登录对话框，创建模板，add模板，创建窗口，ShowWindow,UpDateWindow。 BOOL CFireMapApp:InitInstance() if (CoInitialize(NULL)!=0) AfxMessageBox(初始化COM支持库失败!); exit(1); denglu deng; deng.DoModal(); / CLogo *dlg = new CLogo(); / dlg-Create(IDD_LOGO); / dlg-ShowWindow(SW_SHOW); / dlg-UpdateWindow(); / Sleep(2000); AfxEnableControlContainer(); / Standard initialization / If you are not using these features and wish to reduce the size / of your final executable, you should remove from the following / the specific initialization routines you do not need. #ifdef _AFXDLL Enable3dControls(); / Call this when using MFC in a shared DLL #else Enable3dControlsStatic(); / Call this when linking to MFC statically #endif / Change the registry key under which our settings are stored. / TODO: You should modify this string to be something appropriate / such as the name of your company or organization.
