Need a VB code in excel to close the windows explorer. My macro performs the following function.
  • Opens the window explorer of the desired path on the basis of excel sheet.
  • Then open the specific excel file from the folder opened at step1.
  • Updates the spreadsheet and then closes it.
  • At this step I need to close the explorer window (opened at step 1).
 

Excel Facts

Enter current date or time
Ctrl+: enters current time. Ctrl+; enters current date. Use Ctrl+: Ctrl+; Enter for current date & time.
Hi and welcome to MrExcel.

Getting a reference to the HWND or PID of a given Explorer Window is for some obscure reason very difficult. I know several methods of doing this with other Processes/Windows but none those methods work for Explorer windows. I would love to see if this can be done. I'll keep trying and if anything comes up i'll post it here.

Regards.

I've done some research and some testing but there doesn't seem to be a simple way of doing this.

One cannot use the PID returned by the Shell command and subsequently terminate the Explorer.exe Process via the TerminateProcess API using the returned PID because all the launched Explorer windows run in the same Process as that of the main System Explorer. In other words all new launched Explorer Windows are just different open windows of the same Explorer Process.

Even walking through all the Top level Windows via the EnumWindows API and even catching the creation of the Explorer Window via a CBT hook didn't work !

So the only remaining option is to try and get the hwnd of our target Explorer Window using the FindWindow Function and try to close it programmatically. However another problem comes up with this because each Explorer Window seems to have a different Class name depending on the desired path !

Try experimenting with the EXPLORER_CLASSNAME Constante in the example code below and see if it works by changing the Const from "CabinetWClass" to "ExploreWClass" or vice versa:

Code:
Option Explicit
 
Private Declare Function SendMessage Lib "user32" _
Alias "SendMessageA" _
(ByVal hwnd As Long, _
ByVal wMsg As Long, _
ByVal wParam As Long, _
ByRef lParam As Any) As Long
 
Private Declare Function FindWindow Lib "user32" _
Alias "FindWindowA" _
(ByVal lpClassName As String, _
ByVal lpWindowName As String) As Long
 
Private Const SC_CLOSE = &HF060&
Private Const WM_SYSCOMMAND = &H112
 
Private Const EXPLORER_CLASSNAME As String = "CabinetWClass"
[COLOR=seagreen]'Private Const EXPLORER_CLASSNAME As String = "ExploreWClass"[/COLOR]
 
Sub Test()
 
    Dim lExplhwnd As Long
    Dim lTimer As Long
 
    Shell "explorer.exe C:\", vbMaximizedFocus
 
    [COLOR=seagreen]'======================================[/COLOR]
   [COLOR=seagreen]'this loop is just for illustration pupose.[/COLOR]
    [COLOR=seagreen]'remove this temporary loop and replace it[/COLOR]
   [COLOR=seagreen]'with your Macro stuff here....[/COLOR]
    lTimer = Timer
    Do
        DoEvents
    Loop Until Timer - lTimer >= 3 [COLOR=seagreen]'wait 3 Secs[/COLOR].
   [COLOR=seagreen]'======================================[/COLOR]
 
    lExplhwnd = FindWindow(EXPLORER_CLASSNAME, vbNullString)
 
    If lExplhwnd Then
        SendMessage lExplhwnd, WM_SYSCOMMAND, SC_CLOSE, ByVal 0&
    End If
 
End Sub

The above worked for me on WIN XP . Not sure if this would work on different platforms.

Regards.
