Is it possible to get a menuitem when I have the name in a variable?

I want to disable/enable certain menus based on which modules the user has access to.

All the menunames is stored in a table with the corresponding module number, and I'm writing a function to enable/disable the menus.

 

Regards,

Bjarne Anker

Hi
I use this recursive function on the menu. To start with I call it from the windows, passing MenuId and the string of the item to be found. This logic can be included/used in a menu function that enables/disables the menu item.

of_FindMenuItem (menu am_current, string as_menuitem);/
******************************************
 Description   : Searches a menu item
 Parameters   : am_current: Current menu, as_menuitem: Menu item Name
 Returns        : menu
 ******************************************/
integer li_Counter, li_Max
menu lm_Item, lm_RetItem
 
li_Max = UpperBound( am_Current.Item )
FOR li_Counter = 1 TO li_Max
  lm_Item = am_Current.Item[li_Counter]
  IF lm_Item.ClassName() = as_menuitem THEN // Found
    RETURN lm_Item
  ELSE
    IF UpperBound( lm_Item.Item ) > 0 THEN
      lm_RetItem = of_FindMenuItem( lm_Item, as_MenuItem )
      IF NOT IsNull( lm_RetItem ) THEN
        RETURN lm_RetItem
      END IF
    END IF
  END IF
NEXT
SetNull( lm_Item )
RETURN lm_Item

Thanks Arthur!



This functions is really helpful in how to understand how the menu is built up.

I can use it both for traversing the menu, and to enable/disable the menus I want.

Nevermind, I found the solution shortly after posting the question.

There is a function in PFC, of_GetMenuReference(ref am_source, string find, ref menu) which returns a menu from the item name.

Works perfectly.
