Thread: Loading animation

Hi,

Again I've searched through faq's, Google and forum but haven't found anything that helped.
What I want to do is overwrite a textline on the same line on screen. So instead of writing on a new line everytime, I want to refresh the existing line. For example I'd like to make a small "reading data indicator" like a "loading indicator"

Here's the output as it is now:

Code:

But I'd like to have this output on the same line so it looks like a loading animation.
In other words, how can I shift back to the beginning of a line (like the home key does) and overwrite the on-screen text?

I've tried with backspace '\b' but that doesn't give the right result (dots still shifting to the right or not 'animating' at all).

Hope it's clear, very difficult to explain :S. Thanks in advance for any advice

You'll need to specify what OS and compiler. What you want is OS/compiler specific functions to manipulate the screen. You can use Borland's gotoxy functions, something like the curses library, ANSI escape codes, etc etc.


Quzah.

My OS is Windows XP and I use the Dev-C++ compiler (so gotoxy() wont work?). clrscr() wont work cos there's more info on the screen and I dont want that to be flashing .

just overwrite characters in the same space with a slight delay.

Sorry, I'm not exactly sure what u mean?

Also I'd like to point out that a delay can't be used in this function cos I use it for displaying when a CAN message is received and I dont want a delay in the reception of messages

>when a CAN message is received and I dont want a delay in the reception of messages

try multi threading then.


>so gotoxy() wont work
and check the faq entry on how to gotoxy in a windows console.
