VERIFY( booleanExpression )
Parameters
booleanExpression
Specifies an expression (including pointer values) that evaluates to nonzero or 0.
Remarks
In the debug version of MFC, the VERIFY macro evaluates its argument. If the result is 0, the macro prints a diagnostic message and halts the program. If the condition is nonzero, it does nothing.
The diagnostic message has the form
assertion failed in file <name> in line <num>
where name is the name of the source file and num is the line number of the assertion that failed in the source file.
In the release version of MFC, VERIFY evaluates the expression but does not print or interrupt the program. For example, if the expression is a function call, the call will be made.
