Hello all, I compiled and linked pdcurses with BCC 3.1 under dos and wrote a simple HELLO application just to test if it will work on a symbol handheld computer (a NEC v25 microprocessor based DrDos operating system with a monochorome LCD display(20x8)computer with a build-in barcode scanner mainly used for sales force applications) but it did not work. On symbol, I can use all the stdio functions of Ansi C and if I close the directvideo option of the compiler, can also use conio functions but why pdcurses does not work? My code is something like: win = initscr(); printw("Hello"); wrefresh(); endwin(); Sorry if I wrote the function names wrong. My source is on another computer. After the refresh, the screen goes blank and I see nothing until I type the "cls" dos command. Any suggestions? I am new to curses and pdcurses libraries and all I want is a portable TUI library that I can freely use and pdcurses seems to be the right choice but only if I can step over this problem? -- Best regards, bulent mailto:[EMAIL PROTECTED]
