How can I use: "VarIsNull and VarIsEmpty" in Lazarus
«
on:
June 23, 2016, 11:53:05 pm »
I have the following code from Delphi:
if VarIsNull(ovFolder.Items
) or VarIsEmpty(ovFolder.Items
)} then Continue;
In Lazarus this code give me the error: Identifier not found "VarIsNull" and "VarIsEmpy". The rest of the code from delphi works fine.
Help me please!!

It works the same as in non-ancient (D6+) versions of Delphi: add variants to your uses clause
