Hello All, Please forgive me first of for being vague. It's because I don't have enough knowledge of what it is I'm asking. I have a program that writes "real time" to a .TXT file. Is there a way to do a "real time" thematic for this .TXT file. i.e. every time a new Lat/Long reading is uploaded into the file the point would show up in the map. I have a lot of options like linking this file through a .MDB or the .TXT file itself since it's very (predictably) formatted. The column format looks like this: Lat Long Data Data Data 34.5 -83.6 1 2 3 34.5 -83.6 1 6 2 34.5 -83.6 1 7 1 34.5 -83.6 1 9 3 The MI program needs to look the max value of "Data" for each row and apply the thematic to that value. Any help in this matter would be greatly appreciated. Thank you, Marty Sprenz. ---------------------------------------------------------------------- To unsubscribe from this list, send e-mail to [EMAIL PROTECTED] and put "unsubscribe MAPINFO-L" in the message body, or contact [EMAIL PROTECTED]
