Some Q&A about Windows Shell programming...

Q : 高分请教：最简单的方法得到windows文件所关联的执行程序路径

A :如：
txt文件得到 D:\winnt\notepad.exe
dsw文件得到 D:\Program Files\Microsoft Visual Studio\Common\MSDev98\Bin\MSDEV.EXE

ShellExecute就做到了~~ 请问有什么简单方法可以实现吗？
---------------------------------------------------------------

FindExecutable or AssocQueryString

Q : 快捷方式上的小箭头和文件夹共享上的手是怎么放上去的? 想对shell进行扩展,使指定的部分文件和文件夹图标上叠加一个小图标,要实现什么接口

A :
需要实现的接口是 IShellIconOverlayIdentifier

需要注册的位置是
HKEY_LOCAL_MACHINE\Software\Microsoft\
Windows\CurrentVersion\Explorer\ShellIconOverlayIdentifiers\MyOverlay
(Default) = {MyOverlay CLSID GUID}

在MSDN Creating Icon Overlay Handlers 主题上有比较详细的解释

Q : vc中能否调用windows中拷贝文件的那个进度条?

A :
现在要实现拷贝文件的功能,时间较长.不想自己做个进度条,问能不能调用windows中拷贝文件的那个进度条?

Requirements
Version 5.00 and later of Shell32.dll

Windows NT/2000: Requires Windows 2000.
Windows 95/98/Me: Requires Windows Me.

IProgressDialog
The IProgressDialog interface is exported by the progress dialog box object (CLSID_ProgressDialog). This object is a generic way to show a user how an operation is progressing. It is typically used when deleting, uploading, copying, moving, or downloading large numbers of files.

The progress dialog box object creates a modeless dialog box and allows the client to set its title, animation, text lines, and progress bar. The object then handles updating on a background thread and allows the user to cancel the operation. Optionally, it estimates the time remaining until the operation is complete and displays the information as a line of text.

BUG: PROGDLG_NOMINIMIZE Flag in IProgressDialog::StartProgressDialog() Has No Effect

Q : 关于几个常见的SHELL问题

A
最近在CSDN上经常看到有人发问，怎样实现显示查找文件对话框，显示浏览文件夹对话框，显示关闭Windows对话框，一类的问题，所以我整理了几个常用的SHELL实现的方法。如下：

           IShellDispatch*            pShellDispatch = NULL;
           HRESULT hResult = CoInitialize(NULL);
           if(FAILED(hResult))
           {
                       return;
           }

           hResult = CoCreateInstance(CLSID_Shell,NULL,CLSCTX_INPROC_SERVER,
                       IID_IDispatch,(LPVOID*)&pShellDispatch);
           if(FAILED(hResult))
           {
                       return;
           }

//            COleVariant OleVariant("桌面");
//            COleVariant OleTitle("IShellDispatch test");
//            Folder* pFolder = NULL;
//            hResult = pShellDispatch->BrowseForFolder((LONG)GetSafeHwnd(),
//                        OleTitle.bstrVal,BIF_RETURNONLYFSDIRS,OleVariant,&pFolder);
//显示浏览文件夹对话框

//            hResult = pShellDispatch->CascadeWindows();//层叠窗口

//            COleVariant OleVariant("access.cpl");
//            hResult = pShellDispatch->ControlPanelItem(OleVariant.bstrVal);//打开控制面板的程序

//            COleVariant OleVariant("我的电脑");
//            hResult = pShellDispatch->Explore(OleTitle);//用资源管理器打开文件夹

//            hResult = pShellDispatch->FileRun();//显示运行对话框

//            hResult = pShellDispatch->FindComputer();//显示查找电脑对话框

//            hResult = pShellDispatch->FindFiles();//显示查找文件对话框

//            hResult = pShellDispatch->MinimizeAll();//显示桌面

//            COleVariant OleVariant("我的电脑");
//            hResult = pShellDispatch->Open(OleTitle);//打开文件夹

//            hResult = pShellDispatch->ShutdownWindows();//显示关闭Windows对话框

//            hResult = pShellDispatch->TileHorizontally();//横向平铺窗口

//            hResult = pShellDispatch->TileVertically();//纵向平铺窗口

//            hResult = pShellDispatch->TrayProperties();//显示任务栏属性对话框

//            hResult = pShellDispatch->UndoMinimizeALL();//撤销最小化窗口
