This function is called during verification immediately before a line is displayed and each time a character in the line has been modified. This allows you to set the level of a rule violation and to flag a line so that DLLMsgLinePhase() is called.
Do not display a dialog or message box within this routine. Also, this routine will be called numerous times per line, so the code must be kept as efficient as possible.
void CUSTOMDLL_API DLLRuleLinePhase
( LPDLLRULESTRUCT lpDllRuleStruct );
