MFC problem summary (continuous update)

Problems encountered during the use of MFC and Solutions

Question 1: The compilation prompts "The local function definition is invalid"

The button cannot be added. There is no problem with the button itself, and there is no problem with the event response. It is usually because a function of the program is missing braces and you should check carefully.

Question 2: program debugging

The program can run but there are always unexpected problems. When you need to find the problem, you can set a breakpoint and use the VC debugging skills to slowly locate the problem.
