I have coded my project several months now. And it works fine. Now it has started to give Access Violation error.
It creates Mainform and several other forms in startup. In mainform's on create event it should check and set other forms VISIBLE property. This worked fine, until now. I haven't changed the code, or done any other modifications. Now when i try to read or set forms visible property it gives an error: "Access Violation at address 004499DE in module "program name". Read of address FFFFFFFF."
When i click ok, the program will continue normally.
What causes this and how can i get rid of it ?
Help me !
It's wierd, because i havent changed those routines that affect or read the visible propertys, in several months..
