[RESOLVED] do these database functions require Access Installed?

if i call for these functions to take place inside the mdb database backend from my VB frontend;

database compact & Repair

do they require that Access be installed on the client machines? if so what is an easy way to code into VB (classic) to check if Access is installed?


Cheers

No, I have a compact and repair routine in one of my apps that works fine with and without Access installed. I've included the code below. Hope this helps :wave:

vb Code:

Sub CompactDatabase()
Dim source_path As String
Dim Target_path As String
 
On Error Resume Next
'Compact Database
source_path = App.Path & "\" & SelectedDatabase
Target_path = App.Path & "\CompactResearch.mdb"
 
If compactDB(source_path, Target_path) = False Then
'Need to check if CompactDatabase.mdb is there because it needs to be deleted
    If Dir$(Target_path) <> "" Then
    Kill "" & Target_path & ""
    End If
    
Else
Kill "" & source_path & ""
Name "" & Target_path & "" As "" & source_path & ""
End If
 
End Sub
 
Public Function compactDB(ByVal SOUR_path As String, ByVal DEST_path As String) As Boolean
 
  On Error GoTo Err_compact
  Dim JRO As New JRO.JetEngine
 
' Source and Destination connection path
  Dim DB_sour As String, DB_dest As String
  
  DB_sour = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
           "Data Source=" & SOUR_path & "; Jet OLEDB:Database Password=XYZ123;"
    
   DB_dest = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
           "Data Source=" & DEST_path & "; Jet OLEDB:Database Password=XYZ123;"
           
DoEvents
'Compact Database
JRO.CompactDatabase DB_sour, DB_dest
  
compactDB = True
Exit Function
  
Err_compact:
  compactDB = False
 
End Function

The only time you would need Access installed is if you were doing something that required the database itself to open such as calling a built in Access Report.

excellent thanks
