hallo leute!
gibt es eine möglichkeit direkt von hardwareadressen zu lesen wie mit peek & poke in qbasic?
ich möchte nämlich in einem c++-programm den shift-, numlock- und so abfragen...
in qbasic sieht das so aus:
def seg = 0
a = peek(&H417)
...
gibts sowas in c++???
wenn ja, BITTE schreibt mir wie es geht !
mfg, rotti

direkte hardwarezugriffe sind unter win32 nicht moeglich - zumindest nicht fuer anwendungsprogramme. du _musst_ fuer sowas einen treiber oder ein treiber-aehnliches prgoramm schreiben.
WM_SORRY

schade, da ich noch relativ unvertraut mit c++ bin...

Vielleicht nützt Dir das was:
The GetKeyState function retrieves the status of the specified virtual key. The status specifies whether the key is up, down, or toggled (on, off — alternating each time the key is pressed).
SHORT GetKeyState(
int nVirtKey // virtual-key code
);
Parameter
nVirtKey
Specifies a virtual key. If the desired virtual key is a letter or digit (A through Z, a through z, or 0 through 9), nVirtKey must be set to the ASCII value of that character. For other keys, it must be a virtual-key code.
If a non-English keyboard layout is used, virtual keys with values in the range ASCII A through Z and 0 through 9 are used to specify most of the character keys. For example, for the German keyboard layout, the virtual key of value ASCII O (0x4F) refers to the "o" key, whereas VK_OEM_1 refers to the "o with umlaut" key.
Return Value
If the function succeeds, the return value specifies the status of the given virtual key. If the high-order bit is 1, the key is down; otherwise, it is up. If the low-order bit is 1, the key is toggled. A key, such as the CAPS LOCK key, is toggled if it is turned on. The key is off and untoggled if the low-order bit is 0. A toggle key's indicator light (if any) on the keyboard will be on when the key is toggled, and off when the key is untoggled.
Remarks
The key status returned from this function changes as a given thread reads key messages from its message queue. The status does not reflect the interrupt-level state associated with the hardware. Use the GetAsyncKeyState function to retrieve that information.
An application calls GetKeyState in response to a keyboard-input message. This function retrieves the state of the key when the input message was generated.
To retrieve state information for all the virtual keys, use the GetKeyboardState function.
An application can use the virtual-key code constants VK_SHIFT, VK_CONTROL, and VK_MENU as values for the nVirtKey parameter. This gives the status of the SHIFT, CTRL, or ALT keys without distinguishing between left and right. An application can also use the following virtual-key code constants as values for nVirtKey to distinguish between the left and right instances of those keys:
VK_LSHIFT VK_RSHIFT
VK_LCONTROL VK_RCONTROL
VK_LMENU VK_RMENU
These left- and right-distinguishing constants are available to an application only through the GetKeyboardState, SetKeyboardState, GetAsyncKeyState, GetKeyState, and MapVirtualKey functions.
