Will the destructor be called when the DLL is unloaded? | In a Windows C++ DLL, all global objects (including static members of classes) will be constructed just before the calling of the DllMain with DLL_PROCESS_ATTACH, and they will be destroyed just after the call of the DllMain with DLL_PROCESS_DETACH.

Something like is_int() in PHP is what I am looking for. | I'll assume you want to check a string value. One nice way is the REGEXP operator, matching the string to a regular expression.
