Hello Bill
Talking to myself again but then no one else seemed to know the answer to my
question.
So if anyone else wants to know how to find out if a particular object os of
a secific type, in this case a BetterString object then see below.

After a bit of delving in headers etc I was able to come up with the
following solution.
======================================
HOOKFUNCTION VOID BetterStringFunc(REG(a0, struct Hook *hook), REG(a2,
Object *obj), REG(a1, ULONG *arg))
{
BOOL betterstringshortcut=FALSE;
Object *activewindow=NULL;
Object *window;
Object *actObj;
struct IClass *clpointer;
// Get Active window
struct Node *node = ((struct List *)
xget(MUI_App,MUIA_Application_WindowList))->lh_Head;
while ((window = NextObject ((Object**)&node)) && (activewindow==NULL))
{
if((BOOL)xget(window,MUIA_Window_Activate)) activewindow=window;
}
if(activewindow!=NULL)
{
// Get window active object here
if(actObj = (Object *)xget(activewindow, MUIA_Window_ActiveObject))
{
//Check if Active Object is a betterstring object
clpointer=OCLASS(actObj);
if(clpointer->cl_ID) if
(!strcmp(clpointer->cl_ID,"BetterString.mcc")) betterstringshortcut=TRUE;
}
}
switch (arg[0])
{
case MENU_CONTROL:
if (betterstringshortcut) DoMethod(actObj,
MUIM_BetterString_DoAction, MUIV_BetterString_DoAction_Copy);
else DoMethod(MUI_App,MUIM_CallHook,&ControlHook);
break;
case MENU_PLANET:
if (betterstringshortcut) DoMethod(actObj,
MUIM_BetterString_DoAction, MUIV_BetterString_DoAction_Cut);
else set(MUI_ChoosePlanetWindow, MUIA_Window_Open, TRUE);
break;
case MENU_FIELD:
if (betterstringshortcut) DoMethod(actObj,
MUIM_BetterString_DoAction, MUIV_BetterString_DoAction_Paste);
else set(MUI_FieldWindow, MUIA_Window_Open, TRUE);
break;
case MENU_DISPLAY:
if (betterstringshortcut) DoMethod(actObj,
MUIM_BetterString_DoAction, MUIV_BetterString_DoAction_DecreaseNum);
else set(MUI_DisplayWindow, MUIA_Window_Open, TRUE);
break;
case MENU_ICONIFY:
if (betterstringshortcut) DoMethod(actObj,
MUIM_BetterString_DoAction, MUIV_BetterString_DoAction_IncreaseNum);
else set(MUI_App,MUIA_Application_Iconified,TRUE);
break;
case MENU_QUIT:
if (betterstringshortcut) DoMethod(actObj,
MUIM_BetterString_DoAction, MUIV_BetterString_DoAction_Revert);
else DoMethod(MUI_App,MUIM_Application_ReturnID,
MUIV_Application_ReturnID_Quit);
break;
};
}
MakeStaticHook(BetterStringHook, BetterStringFunc);
