    Code:
    (int)var;
    int(var);
    static_cast<int>(var);
    It should happen naturally i'd think. Afaik DWORD is only a typedef for an unsigned int.

    unsigned long.
    Good class architecture is not like a Swiss Army Knife; it should be more like a well balanced throwing knife.

    hmmm, what seems the difference between
    Code:
    unsigned int;
    and:
    Code:
    unsigned long;
    . I believe an int is a signed long no?

    Well, sizeof(long) >= sizeof(int)

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.
