SHOpenFolderAndSelectItems for explorer replacement program

[MrDoge]

I am making an explorer in ahk, currently, whenever "show in folder", the parent folder is opened, but I can't know which files to select/focus
I think vscode command : file: reveal in file explorer uses SHOpenFolderAndSelectItems,
I went in source code and it uses this I think : shell.showItemInFolder(fullPath) from https://www.electronjs.org/docs/api/shell
chrome : chrome://downloads/, "show in folder", probably does the same thing

I want to do this https://stackoverflow.com/questions/22118653/shopenfolderandselectitems-for-explorer-replacement-program

but i don't know how to do the VARIANT parameter for this IShellWindows::RegisterPending,

here is code
I've got IShellWindows interface

Code: Select all

#NoEnv  ; Recommended for performance and compatibility with future AutoHotkey releases.
#SingleInstance, force
    SendMode Input  ; Recommended for new scripts due to its superior speed and reliability.
SetWorkingDir %A_ScriptDir%  ; Ensures a consistent starting directory.

COM_CoUninitialize()
COM_CoInitialize()

DllCall("Ole32\CoCreateInstance", "Ptr", GUID4String(CLSID_ShellWindows,"{9BA05972-F6A8-11CF-A442-00A0C90A8F39}")
, "int", 0
, "Uint", 23 ;CLSCTX_ALL ;https://altaxo.github.io/AltaxoClassReference/html/T_Altaxo_UnmanagedApi_Ole32_CLSCTX.htm
, "Ptr", GUID4String(IID_IShellWindows,"{85CB6900-4D95-11CF-960C-0080C7F4EE85}")
, "Ptr*", IShellWindows)

threadId:=DllCall("GetCurrentThreadId", UInt)
;IShellWindows::RegisterPending
DllCall(VTable(IShellWindows, 11), "Ptr", IShellWindows
, "Uint", threadId
, "Uint", 0 ;need VARIANT here
, "int", 0 ;null , do I also need a VARIANT here ?
, "Uint", 0x2 ;int ;SWC_3RDPARTY
, "Uint", cookie) ;long

return

f3::
    COM_CoUninitialize()
    Exitapp
    
    COM_CoInitialize()
    {
        Return	DllCall("ole32\CoInitialize", "Uint", 0)
    }
    
    COM_CoUninitialize()
    {
        DllCall("ole32\CoUninitialize")
    }
    VTable(ppv, idx)
    {
        Return   NumGet(NumGet(1*ppv)+A_PtrSize*idx)
    }
    GUID4String(ByRef CLSID, String)
    {
        VarSetCapacity(CLSID, 16,0)
        return DllCall("ole32\CLSIDFromString", "wstr", String, "Ptr", &CLSID) >= 0 ? &CLSID : ""
    }
    GUID(ByRef GUID, sGUID) ; Converts a string to a binary GUID and returns its address.
    {
        VarSetCapacity(GUID, 16, 0)
        return DllCall("ole32\CLSIDFromString", "WStr", sGUID, "Ptr", &GUID) >= 0 ? &GUID : ""
    }

what does this registration do ? and how do I get the files to select/focus after I register ?
is there a function/event that will be called when SHOpenFolderAndSelectItems is called ?

I use this to test SHOpenFolderAndSelectItems, replace folderPath with the parent folder, and files with the names inside you want to focus.

Did you ever figure this out? I'd be really interested in knowing how to do this, thanks!

this open source explorer implemented it
https://github.com/derceg/explorerplusplus/issues/270
this is the commit: (thank derceg)
https://github.com/derceg/explorerplusplus/commit/67c3687f3012330d802d70028f36968788d80aff

@gave92
years later I understand c++ more

this is it:
https://github.com/FuPeiJiang/just_SHOpenFolderAndSelectItems
this can be considered an AHK library port of https://github.com/derceg/explorerplusplus/commit/67c3687f3012330d802d70028f36968788d80aff

___
add for registry (single).ah2 to registry then run test run SHOpenFolderAndSelectItems.ah2 with your directory paths

HKEY_CLASSES_ROOT\Folder\shell -> (default)
AnythingYouWant
HKEY_CLASSES_ROOT\Folder\shell\AnythingYouWant\command -> (default)
"C:\AutoHotkey_2.0-beta.3\AutoHotkey64.exe" "C:\for registry (single).ah2" "%1 "

Thank you so much for completing this. I was about to get my hands dirty.
