Hi everyone

What is the meaning of this ASSERT_VALID

Regards

from the MSDN Library. You really ought to become familiar with it.

ASSERT_VALID
ASSERT_VALID( pObject )

Parameters

pObject

Specifies an object of a class derived from CObject that has an overriding version of the AssertValid member function.

Remarks

Use to test your assumptions about the validity of an object’s internal state. ASSERT_VALID calls the AssertValid member function of the object passed as its argument.

In the Release version of MFC, ASSERT_VALID does nothing. In the Debug version, it validates the pointer, checks against NULL, and calls the object’s own AssertValid member functions. If any of these tests fails, this displays an alert message in the same manner as ASSERT.

Note This function is available only in the Debug version of MFC.
