     Included in this module are several functions to help you in handling with the registry. I have written and tested these as best I can. You may use them at your own risk. I frequently use SetAppKeyValue and GetAppKeyValue without any problems. If you wish to alter or test any of the functions, I strongly advise you to backup your registry first (Start > Run "regedit"). The included functions are: CloseKey, CreateKey, DeleteKey, DeleteKeyStruct, EnumKey, GetAppKeyValue, GetKeyValue, OpenKey, SetAppKeyValue, and SetKeyValue. This code covers: Constants, Functions, GoTo, On Error, Recursion, RegCloseKey API, RegCreateKeyEx API, RegDeleteKey API, RegEnumKeyEx API, RegQueryValueEx API, RegOpenKeyEx API, RegSetValueEx API, and Types.

For my own project I am using some of this code, I was wondering if you could help me! I used the RegDeleteKey to remove Run from the Start menu, and now i cant get it back up. Could you advise me on how to do so,please

I just thought that you should be aware that, when calling on RegSetValueEx, if you pass cbData with the value of zero, it does not copy anything to the registry. That sort of defeats the purpose of calling that function in the first place.
