a simple getch question

I suppose i didnt understand what this means,

Quote:

---

The _getch function reads a single character from the console without echoing. _getche reads a single character from the console and echoes the character read. Neither function can be used to read CTRL+C. When reading a function key or an arrow key, _getch and _getche must be called twice; the first call returns 0 or 0xE0, and the second call returns the actual key code.

how can be call twice? Does not means needs to wait for two press to work? Nevertheless, i can not catch arrow key.

using BC++5.5(commandline free compiler) for dos.

thanks

thank you i will check.

Thanks for this forum and surely people share their experiences.

I am not writing here any code because tried every variation to test.

I tried all experiences in forum i found(c/c++) but no success.

My tests working on win95 but not work on my win98. So, that is not my fault, i think.

My debug resulting only 0xE0 for arrow keys, on my Win98.

I think two options to this,

either win98 keyboard drivers problem, or maybe about my multimedia keyboard. Unfortunately i can not change my keyboard for test now.

Did anybody experienced a problem with catching extended keys(arrows, home, pagedown) in DOS _getch()?

Did anybody experienced such problem?

thanks

Thank you Salem, but as i discussed my last post, i tried all of them in that link too(as others), even i mostly become hopeful in fact.

I am already searching microsoft articles about this situation and find some articles about problems on either updates or config changes on system. But not tried yet.

I am already suspicious on drivers. Because one of the test snippet on the thread which you point me is working on win95(other PC -my friend) but i can not change my keyboard or else. I think i am not the only people experiencing this problem.

Problem is not about programming. That snippet is working in fact, but not on my machine.

Thanks

I suppose my problem about, win98(not SE).

Microsoft Knowledge Base Article - 214408 (Q214408)

is explaining such problem. But is fixed in SE. Maybe somebody looks here in future. Must think this too.
