Today I face some problem: when I try add lines to TMemo on another form:

workingForm.scanLog.Lines.Add('Page ' + link + ' proceed.');

It's returning a error:

What I doing wrong?

Answer 1

Place a breakpoint on that line, and verify that workingForm and scanLog are not nil.

You should either make sure that they are assigned, or you need to check if they are before you use them.
