Why a form jams in visual basic 2010 express?

Answer 1

Depends on your code, you may have an infinite loop being run due several reasons:

- You may have used the wrong symbols ("<" or ">", an example shown below;

Dim Var1 as integer = 20

Do

Var1 = Var1+1

Loop Until Var1 >= 19

This is an example of an infinite loop, sometimes crashing the form. But it depends on your program.
