Hi,
You need to disable the error checking by using the SetErrorMode() Win32 function...

Code: Select all
def_err_mode_ = SetErrorMode(SEM_FAILCRITICALERRORS);


Later, you should restore the previous error mode via...

Code: Select all
SetErrorMode(def_err_mode_);


You may be able to get away with calling these functions in response to the OnEnter and OnExit events, respectively.

HTH,
Damon
