Anyway here's an alternative way, a bit uglier, but it works for me-

bool GetKeyEvent(unsigned char &Scancode, bool &Pressed)
{
DIDEVICEOBJECTDATA TheEvent;
unsigned long ArrayLen= 1;
HRESULT Result;

Result= Keyboard->GetDeviceData(sizeof(DIDEVICEOBJECTDATA), &TheEvent, &ArrayLen, 0);
if (!SUCCEEDED(Result))
{
return false; // no keys pressed
}

if (ArrayLen == 1)
{
Scancode= (unsigned char) TheEvent.dwOfs;
if (TheEvent.dwData & 0x80)
Pressed= true;
else
Pressed= false;
return true;
}
else
return false;
}

Call this in your main loop:

while (GetKeyEvent(Scancode, Pressed))
register this key as pressed/released

You'll need an array of the keys you want to use in your program, and mark them as down/up in the above loop.

Then after the loop you can check your keyarray for the pressed keys.

This also fixes a problem you might run into later, if you have a shoot key for instance- it's possible to press and release the key inbetween calls to GetDeviceState, in which case the keypress would not be caught.

hope this is somewhat useful

I guess i might need to look into buffered directinput,but dont i have to worry about overflows and things then?

Ok i am using directinput for checking keys in my logic loop. Basicly

Keyboard->GetDeviceState( sizeof(diks), &diks );

int KEY(int key){
return diks[key] & 0x80;}

if (KEY(DIK_ESCAPE)) PostMessage(hwnd, WM_DESTROY,0,0);

Ok this works great so far. Now i come to my problem

if (KEY(DIK_UP) && KEY(DIK_LEFT))player1.y-=1, player1.x-=1, player1.dir = DIR_NORTH_WEST;

Ill tell you a bit more bout what im trying to do so that the above might make a little bit more sence. Im using 8-way graphics and i have bitmaps for each direction. The problem is i can never get the diagonal to work. I mean they work if i hold them down but i can't ever get the direction to stay as a diagonal. I guess it sees that one of the direction keys was down for a millisecond longer than the other so it goes up or left ect. So what i need i think is some type of a delay. Sleep(1) works perfectly but kills my framerate very badly.

Any Thoughts on how to get this working?

DIPROPDWORD Props;
Props.diph.dwSize= sizeof(Props);
Props.diph.dwHeaderSize= sizeof(DIPROPHEADER);
Props.diph.dwObj= 0;
Props.diph.dwHow= DIPH_DEVICE;
Props.dwData= 1024;
Keyboard->SetProperty(DIPROP_BUFFERSIZE, &Props.diph);

The dwData member is the buffersize, as long as you're checking the buffer every so often it should never overflow with a big enough buffer.
If it does overflow, directinput handles it- new data is lost, but it won't crash.
