Open an Explorer Window using VBA

I am trying to develop a document management application that uses an Access Data Project front-end. Data about [construction] projects is stored in a MS-SQL database, and I want to use the front end to link to a directory structure on the file server where project related files can be stored. I am using a form to present the project information to the user, and want to give him a button that will open up the relevant folder in a windows explorer window.
 I am very new to VBA and cannot seem to get Shell or ShellExecute to work. My latest attempt is listed below. It returns `Run time error '53': File not found.'
Private Sub cmdOpenFolder_Click()
   
    Dim strFolder, strCommand As String
    Dim x As Variant
   
    strFolder = "c:\"       'ideally this will be a value from the current record
    strCommand = Chr(34) & "EXPLORER.EXE" & strFolder & Chr(34)
   
    x = Shell(strCommand, vbNormalFocus)
   
End Sub

Or, if you really want to go to town

Use the Windows API.

Supply the OpenFile() function with a path and filename or just a path and it will open the the appropriate application, or just explorer if only a path is specified.

Paste the whole lot into a module and practice with the Tester procedure

Private Declare Function apiShellExecute Lib "shell32.dll" Alias "ShellExecuteA" (ByVal HWnd As Long, _
ByVal lpOperation As String, ByVal lpFile As String, ByVal lpParameters As String, _
ByVal lpDirectory As String, ByVal nShowCmd As Long) As Long

Function OpenFile(fileToOpen As String)

Dim retVal As Long, varTaskID As Variant
Dim retStr As String
        retVal = apiShellExecute(0, vbNullString, fileToOpen, vbNullString, vbNullString, 1)
           
    If retVal > 32 Then
        retStr = vbNullString
        retVal = -1
    Else
        Select Case retVal
            Case 31:
                varTaskID = Shell("rundll32.exe shell32.dll,OpenAs_RunDLL " & fileToOpen, 1)
                retVal = (varTaskID <> 0)
            Case 0:
                retStr = "Error: Out of Memory."
            Case 2:
                retStr = "Error: File not found."
            Case 3:
                retStr = "Error: Path not found."
            Case 11:
                retStr = "Error:  Bad File Format"
            Case Else:
        End Select
    End If
    fHandleFile = retVal & IIf(retStr = "", vbNullString, ", " & retStr)
End Function


Sub Tester()
'Will open the file with registered application
x = OpenFile("C:\Sample Files\Sample.docx")

'Will open Explorer at the path supplied
x = OpenFile("C:\Sample Files")


End Sub

Okay, Chris, that works. However, the big problem for me is that I need to use a variable as the folder. I just put the c:\ constant in there because the rest of my syntax was throwing the error. It's defined in the current record as Folder, and resides on the file server. How do I get it into the Shell command?

Like:

Dim str As String
    str = "c:\delete me"
    shell "explorer " & str, vbNormalFocus

you could drop an active x web browser on a form and have it navigate to your file.

Still not working. Here's my latest attempt:

    Dim strFolder As String
    strFolder = Folder
    Shell "explorer" & strFolder, vbNormalFocus

The value of Folder is \\Server\Jobs\Big Project A, as plain text.
Still getting error 53.
Note that I want to open an Explorer folder, not a specific file.
Thanks

Try typing it in initially as hard data and see if it works ... if it does then I suggets folder is not what you think it is ... i.e. it might have control codes therein.

It worked! I can even use the drive mapping to refer to the folder, instead of giving the absolute address.

Thanks for your help.
