GetAsyncKeyState() and the Win32 console
Author
Is it possibe to use GetAsyncKeyState() w/ the win32 console? If so, how?

yep...
how do u normally use it? hmm lets see...
#include <windows.h>
void main()
{
if(GetAsyncKeyState(mekey))...
}

Thanks for the sarcasm, but could you explain a little better, because that doesn''t seem to work right, unless I''m not using it in the right context. This doesn''t work:
#include <windows.h>
main()
{
if(GetAsyncKeyState(VK_SPACE))
{
cout <<"nicely done.";
}
or this.
main()
{
while(1)
{
if(GetAsyncKeyState(VK_SPACE))
{
cout <<"nicely done.";
}
}
}
what am I doing wrong?

hmm i could have sworn i used it in console b4...anyways, here is a c++ method to get a key. ....i got this offa a MSDN example, which you should look up if ur goinu do something in console. its called: "console", or at least thats what it is in my msdn examples folder. ( i may have changed it?) if you want i can send u a zip of it.
#include <windows.h>#include <windowsx.h>#include <iostream.h>int main(void){ BOOL bSuccess; HANDLE hStdIn, hStdOut; /* standard input, output handles */ DWORD dwMode; /* array of console input event records */ INPUT_RECORD inputBuffer; DWORD dwInputEvents; /* number of events actually read */ CONSOLE_SCREEN_BUFFER_INFO csbi; /* used to get cursor position */ bSuccess = GetConsoleScreenBufferInfo(GetStdHandle(STD_OUTPUT_HANDLE), &csbi); hStdOut = GetStdHandle(STD_OUTPUT_HANDLE); hStdIn = GetStdHandle(STD_INPUT_HANDLE); bSuccess = GetConsoleMode(hStdIn, &dwMode); bSuccess = SetConsoleMode(hStdIn, (dwMode & ~(ENABLE_LINE_INPUT | ENABLE_ECHO_INPUT)) | ENABLE_WINDOW_INPUT | ENABLE_MOUSE_INPUT); do { bSuccess = ReadConsoleInput(hStdIn, &inputBuffer, 1, &dwInputEvents); switch (inputBuffer.EventType) { case KEY_EVENT: if (inputBuffer.Event.KeyEvent.bKeyDown) { cout << inputBuffer.Event.KeyEvent.wVirtualKeyCode << endl << inputBuffer.Event.KeyEvent.uChar.AsciiChar << endl; } break; } /* switch */ /* when we receive an esc down key, drop out of do loop */ } while (!(inputBuffer.EventType == KEY_EVENT && inputBuffer.Event.KeyEvent.wVirtualKeyCode == VK_ESCAPE && inputBuffer.Event.KeyEvent.bKeyDown)); return(0);}
hmm the source scriptor sure did some funny color stuff on that... just cut and paste, and see if u can figure it out.
wow it sure looks nasty huh.

It’s been a while since I did this but try this:
#include
void main()
{
int oldtime = GetTickCount();
while(!GetAsyncKeyState(65)) // if the letter A is pressed the programe ends
{
if (GetTickCount() – oldtime > 1000) //checks every 1s
{
if(GetAsyncKeyState(“The key you want to check”))
{
cout <<” the key was pressed”;
}
}
#include
void main()
{
int oldtime = GetTickCount();
while(!GetAsyncKeyState(65)) // if the letter A is pressed the programe ends
{
if (GetTickCount() – oldtime > 1000) //checks every 1s
{
if(GetAsyncKeyState(“The key you want to check”))
{
cout <<” the key was pressed”;
}
}
you could always resort to old c stuff.
#include <conio.h>#include <stdio.h>void main(){ char TestForKey(); char k = 0; enum KEYS {KEY_ESCAPE = 27}; while((k = TestForKey()) != KEY_ESCAPE) { if(k != 0) printf("%c",k); }}char TestForKey() { //if key hit, return >0 char k = 0; if(kbhit()) if (!(k = getch())) k = getch(); //test for extended if = 0 return k; }

Strange... the only correct one was based on some MSDN code. Last time I checked it''s all void main() there.
