c# - Select a file for renaming in SharpShell context menu -

i'm using sharpshell write tiny new shell context menu item copies selected files new subfolder, prompts user directory's new name.

searching stackoverflow, found this answer. however, i'd same in sharpshell.

i somehow have fire svsi_edit @ it, can find buried deep in sharpshell.interop, i'm not sure how of works. can't find documentation or code samples whatsoever.

(edit: think finding out how pidl file name start, maybe don't need @ all?)

you can start creating project sharpshell register new shell context menu in tutorial.

here, have define class implementing sharpcontextmenu. simplicity create menu filetype , show it:

[comvisible(true)] [comserverassociation(associationtype.allfiles)] public class copyfilesextension : sharpcontextmenu {     protected override bool canshowmenu()     {         return true;     }      protected override contextmenustrip createmenu()     {         var menu = new contextmenustrip();          var copyfiles = new toolstripmenuitem { text = "copy files folder..." };          copyfiles.click += (sender, args) => copyfiles();         menu.items.add(copyfiles);          return menu;     }      private void copyfiles()     {         ...     } }  

but i'm sure you've done this, problem here implement copyfiles() method.

one way showing dialog asking name of folder, this:

then, implement copyfiles() so:

private void copyfiles() {     using (var dialog = new copyfiledialog())     {         if (dialog.showdialog() == dialogresult.ok)         {             var folder = path.getdirectoryname(selecteditempaths.first());             var newfolder = path.combine(folder, dialog.foldername);              directory.createdirectory(newfolder);              foreach (var path in selecteditempaths)             {                 var newpath = path.combine(newfolder, path.getfilename(path));                 file.move(path, newpath);             }         }     } } 

in above code, asked name of folder, create folder , move selected files folder.

however, if want using rename command in windows explorer can start importing needed win32 functions:

class win32 {     [dllimport("shell32.dll", charset = charset.unicode)]     public static extern intptr ilcreatefrompath([in, marshalas(unmanagedtype.lpwstr)] string pszpath);      [dllimport("shell32.dll")]     public static extern int shopenfolderandselectitems(intptr pidlfolder, uint cidl, intptr[] apidl, int dwflags);      [dllimport("shell32.dll")]     public static extern void ilfree(intptr pidl); } 

• ilcreatefrompath allows pidl filename.
• shopenfolderandselectitems allow select file , send rename command.
• ilfree frees unmanaged pidl created.

with these win32 functions can defines copyfiles() follows:

private void copyfiles() {     var folder = path.getdirectoryname(selecteditempaths.first());     var newfolder = path.combine(folder, "new folder");     directory.createdirectory(newfolder);      foreach (var path in selecteditempaths)     {         var newpath = path.combine(newfolder, path.getfilename(path));         file.move(path, newpath);     }      renameinexplorer(newfolder); }   private static void renameinexplorer(string itempath) {     intptr folder = win32.ilcreatefrompath(path.getdirectoryname(itempath));     intptr file = win32.ilcreatefrompath(itempath);      try     {         win32.shopenfolderandselectitems(folder, 1, new[] { file }, 1);     }         {         win32.ilfree(folder);         win32.ilfree(file);     } } 

we can't use sharpshell.interop.shell32 since method available in class shellexecuteex() used launch new processes.
