Auto Updating from Excel

Hello,

I need help regarding Amibroker.

1. Has anyone set up DDE link with universal plugin to import data from Excel sheet, if so plaese tell me the datails. Will like to discuss even in a chat


2. What is the method to invoke updation of quotes in Amibroker from ascii file automatically, i mean is there a commend line syntex that can be put in a macro in excel sheet to update quotes in Amibroker. I have seen automatic updation from ascii file in CoolRC and also in Satya's program

Thanks in advance
