Hey!


Ich würde gerne für mein ganze Applikation gültig ein Hotkey für die rechte Strg - Taste einbauen, so dass ich beim Drücken und beim Loslassen eine spezielle Procedure schreiben kann.

Könntet ihr mir diesbezüglich einen Tipp geben, wie ich das realisieren kann?

Willst du die Strg-Taste prinzipiell als Hotkey verwenden oder in Kombination mit anderen Events, wie z.B. OnClick ?

Es gibt übrigends eine globale API-Funktion, mit welcher du den Tastenstatus abfragen kannst , falls du die brauchst:

Zitat:

GetKeyState 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 ); Parameters nVirtKey [in] 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 Values The return value specifies the status of the specified virtual key, as follows: 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 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. Example Code For an example, see Displaying Keyboard Input. Requirements Windows NT/2000/XP: Included in Windows NT 3.1 and later. Windows 95/98/Me: Included in Windows 95 and later. Header: Declared in Winuser.h; include Windows.h. Library: Use User32.lib.

Ach ja ... durch drücken von der Strg-Taste alleine wir keine Windows Message geschickt soweit mir bekannt ist.
