button to open a file in a word processor 1

[xxhockeyplaya311]

i made most of my dialog already and i cant figure out how to make my program open a file wen i click the button
so if i had a file called info.txt under my documents and i have a button called info how would i make the button open that

ShellExecute(NULL, "open", "info.txt", NULL, NULL, SW_SHOW);
