Application.GetOpenFileName() question

To All,

I'm trying to get the results of the GetOpenFileName() to filter all
files in the directory so that only those files that begin with the
letters: "ROSTER" are presented as a choice to Select from.
Currently, my code presents all .xls files in the directory and when
the dialog box pops up, I have to type in the 'FileName' box: ROSTER*
(then tab key) - only then do the filtered results of the dialogue
box match what I'm attempting to do through code ...

Any guidance would be greatly appreciated ...

Dim sDir As String
sDir = ThisWorkbook.Path ' Set path = to directory workbook is
stored in
Dim fnROSTER_MASTER As Variant
Dim strFilter As String: Dim strTitle As Variant
strFilter = "Excel (*.xls),*.xls" ' Another Example of filtered
input
strTitle = "SELECT ROSTER file"
ChDrive sDir
ChDir sDir
' Get the CPC file name
fnROSTER_MASTER = Application.GetOpenFilename(strFilter,
Title:=strTitle)
' Did USER abort/cancel the reguest?
If fnROSTER_MASTER = False Then
Exit Function
End If

To the best of my knowledge, as you have discovered, GetOpenFileName does
not support partial name filtering.

You can use APIs to do it.

Create a class module and name it clsGetOpenFilename, and then add the code
at the end.

You can use it like so to get the name, you will still have to open it as
with the VBA function

Sub TestFileOpen()
Dim cGOPF As clsGetOpenFilename
Dim aryFiles

Set cGOPF = New clsGetOpenFilename
With cGOPF
.FileName = "*A&P*.xls"
.FileType = "Excel Files (*.xls)"
.MultiFile = "N"
If .SelectFile Then
MsgBox .SelectedFiles(1)
End If
End With
End Sub
