To convert a 32-bit Microsoft Access database to a 64-bit version, you need to address compatibility issues, especially with VBA code and ActiveX controls. Below is a step-by-step guide:
Example: Basic Conversion Steps
Open the Database in 64-bit Access: Copy the .accdb file to a system with 64-bit Access installed. Open the file directly in the 64-bit Access application. Most databases will work without modification unless they contain specific 32-bit dependencies.
Update VBA Code: Modify any Declare statements in VBA to include the PtrSafe keyword for compatibility with 64-bit systems. Example: #If VBA7 Then Declare PtrSafe Sub MyFunction Lib "user32" (ByVal hwnd As Long) #Else Declare Sub MyFunction Lib "user32" (ByVal hwnd As Long) #End If
Check for ActiveX Controls: Replace any 32-bit ActiveX controls or third-party libraries with their 64-bit equivalents, as these are not compatible with a 64-bit environment.
