RegDeleteKey error

[Philip Stapleton]

I'm trying to delete a key from the VB settings area with

Sub main()
Dim key As Long
If RegOpenKeyEx(HKEY_CURRENT_USER, "Software\VB and VBA Program
Settings\", 0, KEY_ALL_ACCESS, key) = 0 Then
MsgBox RegDeleteKey(key, "RadarTutor")
End If
End Sub

The Open works OK but the Delete returns an error code of 5 - however,
Regedit shows a Key called HKEY_CURRENT_USER\Software\VB and VBA Program
Settings\RadarTutor

What am I doing wrong?

Hi

I don't know about VB, but for VBScript/WMI you can't delete a key
that has subkeys, you need to create a recursive sub that starts the
deleting at the end of the registry branch, like this:


strComputer = "." ' use "." for local computer

Const HKLM = &H80000002 'HKEY_LOCAL_MACHINE

Set oReg = GetObject _
("winmgmts:{impersonationLevel=impersonate}!\\" _
& strComputer & "\root\default:StdRegProv")

DeleteRegistryKey HKLM, "SOFTWARE\SomeKey"


Sub DeleteRegistryKey(ByVal sHive, ByVal sKey)
Dim aSubKeys, sSubKey, iRC
On Error Resume Next
iRC = oReg.EnumKey(sHive, sKey, aSubKeys)
If iRC = 0 And IsArray(aSubKeys) Then
For Each sSubKey In aSubKeys
If Err.Number <> 0 Then
Err.Clear
Exit Sub
End If
DeleteRegistryKey sHive, sKey & "\" & sSubKey
Next
End If
oReg.DeleteKey sHive, sKey
End Sub

The Mount/\Command ".RegDeleteKey" will completely delete a registry key
including all subkeys from the command line (USE WITH CAUTION!).
