exception

LastInput.time is an Integer and m_idleTime is an Integer too. This line sometimes generates an Overflow exception, I think that this happens when both values are big negative values.

(Environment.TickCount - lastInput.time) > m_idleTime

How can I avoid that? With casting?

(CType(Environment.TickCount,Long) - CType(lastInput.time,Long)) > m_idleTime

Or maybe with this cast?

CType((Environment.TickCount - lastInput.time),Long) > m_idleTime

Thanks in advance.

Cast from Void* to TYPE* using C++ style cast: static_cast or reinterpret_cast

as seen on Stack Overflow - Search for 'Stack Overflow'
So if your converting from Void* to Type* or from Type* to Void* should you use: void func(void *p) { Params *params = static_cast<Params*>(p); } or void func(void *p) { Params *params = reinterpret_cast<Params*>(p); } To me static_cast seems the more correct but I've seen… >>> More

Is there a general way to check for an overflow or an underflow of a given data type (uint32, int etc.)? I am doing something like this: uint32 a,b,c; ... //initialize a,b,c if(b < c) { a -= (c - b) } When I print a after some iterations, it displays a large number like: 4294963846. >>> More
