Suspicious pointer assignment - wallace - 03-24-2006
Code:
TYPE two3tree
root as two3node ptr
size as integer
depth as integer
AddNode as Sub(value as integer)
END TYPE
SUB AddNode(value as integer)
If this.root = 0 then
this.root = NewTwo3Node(value)
else
dim p as Two3Node ptr
p = this.root
end if
this.size = this.size + 1
END SUBNewTwo3Node returns a Two3Node ptr but that like gives me an Implicit conversion warning and p = this.root gives me the suspicious pointer assignement warning. What's going on?

Is this a global variable? Looks like it should be a parameter. ie., there is no implicit this, reference or pointer. You'll have to pass the address - or reference - of an 'object' to it's 'member functions' manually.

Yeah, function pointers are the same as in C - not member functions of classes. Make sure you use Option Explicit to catch undeclared variables.

O, I thought this worked the same was as it did in C++. There is no way to access a subs invoking data type from within the sub?
ie:
Code:
DIM temp as two3tree
temp = NewTwo3Tree
temp.AddNode(6)There is no way to access temp from inside the AddNode sub without passing having it be a parameter?

Correct, it must be a parameter. hopefully fb will move rapidly towards a move to a gcc frontend, which will give us oop and lead basic users once and for all into the promised land...
er.. sorry i got carried away there :o
