It's an operation on a flag. You need to understand bitoperations (AND, OR, NOT, XOR..) for that. This line deletes the flag WS_MINIMIZE from the intStyle flagmask. More reading: Using Bitwise operators on flags , http://www.codeproject.com/Articles/13740/The-Beginner-s-Guide-to-Using-Enum-Flags.

See this for the & operator.

And this for the ~ operator

They are bitwise operators. The first one is a bitwise AND. The second one performs a bitwise complement operation.

This is a bitwise operation.
