Further adventures in migrating to 64 bit (1 Viewer)

[LanaR]

I have the following code under a button, which opens the file explorer window, and then moves the selected document to the target file and notes its location in the DB. In 64 bit the file explorer windows does not open and the MsgBox "File selection was canceled.", vbInformation is shown

Private Sub Command115_Click()

On Error GoTo Err_bBrowse_Click
  
'check if tasting note already attached
'if no note then add PDF Location

   If Me.tbFile = "" Or IsNull(Me.tbFile) Then
  
  
    Dim strFilter As String
    Dim lngFlags As Long
    Dim varFileName As Variant

'    & vbNullChar & "All Files (*.*)" & vbNullChar & "*.*"
'    strFilter = "Access Files (*.mdb)" & vbNullChar & "*.mdb*"
    strFilter = "All Files (*.*)" & vbNullChar & "*.*"

    lngFlags = tscFNPathMustExist Or tscFNFileMustExist Or tscFNHideReadOnly

[arnelgp]

you upload your db so someone can convert it to x64 code.

 

[LanaR]

Sorry, it's too big. I suspect the problem lies in this portion of the code;

varFileName = tsGetFileFromUser( _
    fOpenFile:=True, _
    strFilter:=strFilter, _
    rlngflags:=lngFlags, _
    strInitialDir:="C:\Windows\", _
    strDialogTitle:="Find File (Select The File And Click The Open Button)")
    'remove the strInitialDir:="C:\Windows\", _ line if you do not want the Browser to open at a specific location

as varFileName is returning a null value

 

[arnelgp]

i found it on the net.
test and replace your code with this one:
there is a test sub(), run it.

Thank you ever so much @arnelgp works a treat

Just had to insert the PtrSafe attribute in a couple of locations
