Get ID of option in dropdown?

#1 Figured it out.

function GuiPopUpMenuCtrl::getID(%this, %string)
{
   for(%count = 0; %count < %highestNumberofIDs; %count++) // In my case %highestNumberofIDs = 96
   {
      $strng = strlwr(%this.getTextById(%count));
      if(strcmp($strng,%string) == 0)
      {
         return %count;
         break;
      }
      else
      {
         
      }
   }
}

#2 Alternatively (although not equivalently)

Quote:
GuiPopupMenuCtrl::findText( string text ) -> integer ID - Returns the position of the first entry containing the specified text.

Or, using another class method:

Quote:
GuiPopupMenuCtrl::size() -> integer size - Get the size of the menu: the number of entries in it.

you can simplify your function, avoiding a magic number, the use of a global variable, and a call to strcmp(), by doing something like:

function GuiPopUpMenuCtrl::getIDByText(%this, %string)
{
   %size   = %this.size() ; 
   %string = strlwr( %string ) ; 
   for( %count = 0; %count < %size; %count++ ) 
   {
      if ( strlwr( %this.getTextById( %count ) ) $= %string ) 
         return
            %count ; 
   }
   return
      -1 ; 
}

where we have added an explicit return value in the case of no hits.
