I suggest that you start somewhere like this topic.
Put a breakpoint in your Form1_Load method somewhere near to where you define ipPort and step through the code. The exception is telling you that you're trying to use that variable before its been assigned.

i put a breakpoint near the 'form1' loading function, but it still did not work. but, IpPort is a part of NUget application for visual studio. also known as "supersimpleTCP." also, one more thing. IpPort i am pretty sure already has a defined value in the package.

Hi @Daniel Shepherd ,
In order to find the cause of the problem more accurately, please provide the code in your Form1_Load to reproduce the problem.
