发送文件夹重命名命令的Windows资源管理器 [英] Send Folder Rename Command to Windows Explorer

问题描述

我有一个外壳扩展在.NET中提出，创建文件夹（可以把它作为一个上下文菜单中选择New - >新建文件夹选项克隆），并使用一个输入框输入来自用户的文件夹的名称。相反，我要的文件夹发送rename命令到已经打开 Windows资源管理器窗口。应该就像浏览器是如何让我们命名一个新的文件夹：

I have a shell extension made in .NET that creates folders (think of it as a context menu New -> New Folder option clone) and uses a InputBox to input the name of the folder from the user. Instead I want to send the rename command on the folder to the already open Windows Explorer window. It should be just like how Explorer lets us name a new folder:

在搜索，我发现这一点：<一href="http://stackoverflow.com/questions/6258846/windows-explorer-shell-extension-create-file-and-enter-rename-mode">Windows资源管理器外壳扩展：创建文件，并Enter]键，重新命名＆QUOT;模式。它说，使用与 SVSI_EDIT 标志 IShellView ::的SelectItem 功能。我如何做到这一点的。NET？如果是这样的辛苦，有另一种方式做同样的？

On searching, I found this : Windows Explorer Shell Extension: create file and enter "rename" mode. It says to use the IShellView::SelectItem function with the SVSI_EDIT flag. How do I do that with .NET? If that's hard, is there another way to do the same?

推荐答案

下面是一些code，做这样的事情。您可以使用这样的：

Here is some code that does this kind of things. You use it like this:

private void button1_Click(object sender, EventArgs e)
{
    SelectItemInExplorer(Handle, @"d:\temp\new folder", true);
}

而code：

And the code:

public static void SelectItemInExplorer(IntPtr hwnd, string itemPath, bool edit)
{
    if (itemPath == null)
        throw new ArgumentNullException("itemPath");

    IntPtr folder = PathToAbsolutePIDL(hwnd, Path.GetDirectoryName(itemPath));
    IntPtr file = PathToAbsolutePIDL(hwnd, itemPath);
    try
    {
        SHOpenFolderAndSelectItems(folder, 1, new[] { file }, edit ? 1 : 0);
    }
    finally
    {
        ILFree(folder);
        ILFree(file);
    }
}

[DllImport("shell32.dll")]
private static extern int SHOpenFolderAndSelectItems(IntPtr pidlFolder, uint cidl, IntPtr[] apidl, int dwFlags);

[DllImport("shell32.dll")]
private static extern void ILFree(IntPtr pidl);

[DllImport("shell32.dll")]
private static extern int SHGetDesktopFolder(out IShellFolder ppshf);

[DllImport("ole32.dll")]
private static extern int CreateBindCtx(int reserved, out IBindCtx ppbc);

[ComImport, Guid("000214E6-0000-0000-C000-000000000046"), InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]
internal interface IShellFolder
{
    void ParseDisplayName(IntPtr hwnd, IBindCtx pbc, [In, MarshalAs(UnmanagedType.LPWStr)] string pszDisplayName, out uint pchEaten, out IntPtr ppidl, ref uint pdwAttributes);
    // NOTE: we declared only what we needed...
}

private static IntPtr GetShellFolderChildrenRelativePIDL(IntPtr hwnd, IShellFolder parentFolder, string displayName)
{
    IBindCtx bindCtx;
    CreateBindCtx(0, out bindCtx);
    uint pchEaten;
    uint pdwAttributes = 0;
    IntPtr ppidl;
    parentFolder.ParseDisplayName(hwnd, bindCtx, displayName, out pchEaten, out ppidl, ref pdwAttributes);
    return ppidl;
}

private static IntPtr PathToAbsolutePIDL(IntPtr hwnd, string path)
{
    IShellFolder desktopFolder;
    SHGetDesktopFolder(out desktopFolder);
    return GetShellFolderChildrenRelativePIDL(hwnd, desktopFolder, path);
}
