How come no matter what i do, it makes the value 2?

If i set it to &HFFFFFFFF then it makes the value 3, but setting it to -1, brings it back to 2, that's so wierd.

I'm trying to work out how to make this value swap between 1 & 0.

Yes i've look and researched how to set dWords, but nothing has helped.

Try setting "Data As Variant" to a Long. I also think you're missing out a step there. The handle from RegCreateKey refers to the "Subkey", not the "Value Name", which is the handle you actually need. This may give you ideas:

vb Code:

Public Function RegWriteDword(lngHKey As Long, strSubKey As String, strValueName As String, lngDwordDat As Long) As Long
'Create the subkey, value name and respective DWORD value.
   Dim lngRetval     As Long
   Dim lngKeyHandle  As Long
 
'Set the default return value.
   RegWriteDword = ERROR_FAILED '999
'Create the key.
   If RegCreateKeyEx(lngHKey, strSubKey, 0&, 0&, REG_OPTION_NON_VOLATILE, KEY_CREATE_SUB_KEY, ByVal 0&, lngKeyHandle, lngRetval) = ERROR_SUCCESS Then
'Open the new key.
      If RegOpenKeyEx(lngHKey, strSubKey, 0&, KEY_SET_VALUE, lngKeyHandle) = ERROR_SUCCESS Then
'Write it to the registry, and return a code.
         RegWriteDword = RegSetValueEx(lngKeyHandle, strValueName, 0&, REG_DWORD, lngDwordDat, Len(lngDwordDat))
      End If
   End If
'Close any key opened with RegCreateKeyEx.
   Call RegCloseKey(lngKeyHandle)
End Function

Thanks, setting it to a long fixed it. I kept trying integer and all sorts of other types that would fit it, but i never tried long!

Nahh, I'm not, this key will always exist... if it doesn't well... the computer doesn't deserve to run my program =p.
