标题：Delphi 动态数组I was stuck the whole afternoon in debugging... finally i found something interesting...
Every time Delphi's Dynamic Array , (setLength fun) is extended, the original array cells' addresses may be changed...
Because I use TTreeView to link its Data (Pointer) to a particular cell of a dynamic array.
e.g.
TreeView.Data:=@dynamic_array[i];
and
unfortunately, the program adds one cell to dynamic_array somewhere...
setLength(dynamic_array,length(dynamic_array)+1);
the original cells' address are totally different, which is really confusing....
anyway, i solved this by taking the alternative...
TreeView.Data:=Pointer(i);
when i use it, i go for something like this..
dynamic_array[integer(TreeView.Data)];
Haha, everything works out finally.
