How to edit Windows registry using Access VBA?

#1. How to edit Windows registry using access VBA? To edit the Windows registry using Access VBA, you can use the RegWrite method of the WshShell object. Here’s an example:

vbnetCopy codeDim WshShell As Object
Set WshShell = CreateObject("WScript.Shell")

' Set the registry value
WshShell.RegWrite "HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Access\Security\VBAWarnings", 1, "REG_DWORD"

In this example, we are setting the VBAWarnings value under the Security key in the Windows registry to 1. You can modify this code to set any other registry value you want.

Note: Modifying the Windows registry can have serious consequences. You should always make a backup of the registry before making any changes and be very careful when editing it.

#2 How to edit Windows registry using Access VBA?

To edit the Windows Registry using Access VBA, you can use the RegWrite function from the Microsoft.Win32.Registry namespace. Here’s an example code that shows how to modify a registry key value:

vbnetCopy codeDim regKey As Microsoft.Win32.RegistryKey
Set regKey = Microsoft.Win32.Registry.CurrentUser.OpenSubKey("Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders", True)

' Modify the value of the "Desktop" key
regKey.SetValue("Desktop", "C:\MyNewDesktopFolder")

' Close the registry key
regKey.Close

In this example, we are opening the registry key HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders and modifying the value of the “Desktop” key to the path C:\MyNewDesktopFolder.

Note that the RegWrite the function can be used to add or delete registry keys and values as well. Be careful when modifying the registry as it can cause serious problems if done incorrectly. Always make sure to back up the registry before making any changes.

#3 How to edit Windows registry using access VBA?

Editing the Windows registry using Access VBA requires the use of the Windows API functions. Here’s an example of how you can modify a registry key value using Access VBA:

1. First, add the following API declarations to the top of your VBA module:

vbCopy codePrivate Declare Function RegOpenKeyEx Lib "advapi32.dll" _
    Alias "RegOpenKeyExA" (ByVal hKey As Long, _
    ByVal lpSubKey As String, ByVal ulOptions As Long, _
    ByVal samDesired As Long, ByRef phkResult As Long) As Long

Private Declare Function RegSetValueEx Lib "advapi32.dll" _
    Alias "RegSetValueExA" (ByVal hKey As Long, _
    ByVal lpValueName As String, ByVal Reserved As Long, _
    ByVal dwType As Long, lpData As Any, ByVal cbData As Long) As Long

Private Declare Function RegCloseKey Lib "advapi32.dll" _
    (ByVal hKey As Long) As Long

2. Next, write a function to modify the registry key value. The function should take three arguments: the name of the key to modify, the new value to set, and the registry key location. Here’s an example function that modifies a DWORD value:

vbCopy codeFunction ModifyRegistryValue(ByVal sKeyName As String, _
    ByVal sValue As Long, ByVal sKeyPath As String) As Boolean
    Dim hKey As Long
    Dim lResult As Long
    Dim lValueType As Long
    Dim lDataSize As Long
    Dim lValue As Long
    
    ' Open the registry key
    lResult = RegOpenKeyEx(HKEY_CURRENT_USER, sKeyPath, _
        0, KEY_WRITE, hKey)
    
    If lResult = ERROR_SUCCESS Then
        ' Set the registry value
        lValue = sValue
        lValueType = REG_DWORD
        lDataSize = Len(lValue)
        
        lResult = RegSetValueEx(hKey, sKeyName, 0, _
            lValueType, lValue, lDataSize)
        
        If lResult = ERROR_SUCCESS Then
            ModifyRegistryValue = True
        End If
    End If
    
    ' Close the registry key
    lResult = RegCloseKey(hKey)
End Function

3. Finally, you can call the ModifyRegistryValue function to modify the registry key value. For example, to modify the value of the HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced\HideFileExt registry key to 1 (to hide file extensions), you can use the following code:

vbCopy codeModifyRegistryValue "HideFileExt", 1, "Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced"

#4 How to edit Windows registry using access vba?

To edit Windows Registry using Access VBA, you can use the RegWrite function provided by Microsoft Windows Script Host Object Model. The following steps show how to add a new entry to the Windows Registry using Access VBA:

1. Add a reference to the Windows Script Host Object Model to your Access VBA project.
2. Use the RegWrite function to write the new entry to the Registry. The syntax for the RegWrite function is:RegWrite(hkey, keyname, valuetype, value)where:
   • hkey is the HKEY constant that specifies the root key of the Registry branch you want to write to. For example, HKEY_CURRENT_USER for the current user’s Registry branch.
   • keyname is the name of the Registry key you want to write to. This should be a string value.
   • valuetype is the data type of the value you want to write. This should be a constant value such as REG_SZ for a string value or REG_DWORD for a numeric value.
   • value is the actual value you want to write to the Registry. This should be a string or numeric value, depending on the data type specified in valuetype.
   For example, the following code adds a new entry to the Registry under HKEY_CURRENT_USER\Software\MyApp:vbnetCopy codeDim WSHShell As Object Set WSHShell = CreateObject("WScript.Shell") WSHShell.RegWrite "HKEY_CURRENT_USER\Software\MyApp\MySetting", "MyValue", "REG_SZ"
3. Remember to close the Windows Script Host Object when you are done using it. You can do this by setting the object variable to Nothing. For example:mathematicaCopy codeSet WSHShell = Nothing

Note: Be very careful when editing the Windows registry, as incorrect modifications can cause serious problems with your system. Always back up the registry before making any changes.
