VBA - How to open folder without knowing the full name - excel

Question

I'm trying to open a folder where I don't know the full path.
For example, the parent folder dir is "D:\Documents" and the folder I want to open is called "22.111 - PROJECT_NAME", where I know the code, but don't know the name. I've tried with "*", but no luck.
Sub OpenFolder()
On Error GoTo Err_cmdExplore_Click
Dim Code As String
Code = Range("A1").Value
GoToFolder = "C:\Windows\explorer.exe D:\Documents\" & Code & "*"
Call Shell(GoToFolder, 1)
Exit_cmdExplore_Click:
Exit Sub
Err_cmdExplore_Click:
MsgBox ("Pasta não encontrada")
Resume Exit_cmdExplore_Click
End Sub

Answer 1

Found the answer on another forum (mrexcel.com), leaving it below for anyone that faces the same problem:
Public Sub Find_and_Open_Folder()
Dim Code As String
Dim targetFolder As String
Code = Range("A1").Value
targetFolder = Dir("D:\Documents\" & Code & "*", vbDirectory)
If targetFolder <> vbNullString Then
Shell "explorer.exe """ & "D:\Documents\" & targetFolder & """", vbNormalFocus
Else
MsgBox "Folder matching D:\Documents\" & Code & "* not found"
End If
End Sub

With the parent folder available and the knowledge that the subfolder starts with 22.111, you could loop through all subfolders in the parent folder, and list all the potential matches using InStr. Example of how you might do this:
Sub CodeSnippet()
Dim myFolderName As String
'GetFolders returns array
Dim folderNamesWithPattern As Variant
'searching for "22.111" at 1st pos in string of potential subfolder
folderNamesWithPattern = GetFolders("D:\Documents", "22.111", 1)
If UBound(folderNamesWithPattern) > 0 Then
'more than one folder that meets your pattern:
'decide what to do
Else
'only one entry in array, this is your folder or if "" then ( no such folder | parent folder does not exist )
myFolderName = folderNamesWithPattern(0)
End If
End Sub
Function GetFolders(strDirectory As String, pattern As String, position As Long) As Variant
Dim objFSO As Object
Dim objFolders As Object
Dim objFolder As Object
'create filesystem obj
Set objFSO = CreateObject("Scripting.FileSystemObject")
'create folder obj and access subfolders property
On Error GoTo errorHandler
Set objFolders = objFSO.GetFolder(strDirectory).SubFolders
'dim array for matches
Dim arrFolderNames() As Variant
arrFolderNames = Array()
'loop through all folders
For Each objFolder In objFolders
'InStr() returns 0 if not found | index 1st char in string if found
If InStr(objFolder.Name, pattern) = 1 Then
'add match to array
ReDim Preserve arrFolderNames(UBound(arrFolderNames) + 1)
arrFolderNames(UBound(arrFolderNames)) = objFolder.Name
End If
Next objFolder
'assign array for return
GetFolders = arrFolderNames
errorHandler:
If objFolders Is Nothing Then
'parent folder does not exist
GetFolders = Array("")
ElseIf UBound(arrFolderNames) = -1 Then
'we never found a subfolder that starts with pattern
GetFolders = Array("")
End If
End Function

Explore a Folder Using Workbook.FollowHyperlink
Workbook.FollowHyperlink method (MSDocs)
A Known Worksheet in the Workbook Containing This Code (ThisWorkbook)
Sub ExploreFolder()
Const iFolderPath As String = "D:\Documents\"
Dim wb As Workbook: Set wb = ThisWorkbook ' workbook containing this code
Dim ws As Worksheet: Set ws = wb.Worksheets("Sheet1")
Dim Code As String: Code = CStr(ws.Range("A1").Value)
Dim dFolderPattern As String: dFolderPattern = iFolderPath & Code & "*"
Dim dFolder As String: dFolder = Dir(dFolderPattern, vbDirectory)
If Len(dFolder) > 0 Then
wb.FollowHyperlink iFolderPath & dFolder
Else
MsgBox "A folder matching the pattern '" & dFolderPattern _
& "' was not found.", vbCritical, "Explore Folder"
End If
End Sub
ActiveSheet (not recommended)
Sub ExploreFolderActiveSheet()
Const iFolderPath As String = "D:\Documents\"
Dim ws As Worksheet: Set ws = ActiveSheet
Dim Code As String: Code = CStr(ws.Range("A1").Value)
Dim dFolderPattern As String: dFolderPattern = iFolderPath & Code & "*"
Dim dFolder As String: dFolder = Dir(dFolderPattern, vbDirectory)
If Len(dFolder) > 0 Then
ws.Parent.FollowHyperlink iFolderPath & dFolder
Else
MsgBox "A folder matching the pattern '" & dFolderPattern _
& "' was not found.", vbCritical, "Explore Folder"
End If
End Sub
