Blocking start menu

[hax0r]

I have created an app that requires the user to only be able to press certain keys on the keyboard, is there a way to block keys like the start meny key?

Thanks in advance.

Yes, it's possible. Please send us an email to support@swfkit.com, we'll send you a sample.

I did and no response.

I found this;

dllimport "user32.dll" stdcall Boolean RegisterHotKey(long, int, unsigned int, unsigned int);
dllimport "user32.dll" stdcall Boolean UnregisterHotKey(long, int);

var IDHOT_SNAPDESKTOP = -2;
var IDHOT_SNAPWINDOW = -1;

var MOD_ALT = 0x0001;
var VK_SNAPSHOT = 0x2c;

var wnd = getMainWnd();
// disable the print screen key
RegisterHotKey(wnd.handle, IDHOT_SNAPDESKTOP, 0, VK_SNAPSHOT);
// disable the alt + printscrn key combine
RegisterHotKey(wnd.handle, IDHOT_SNAPWINDOW, MOD_ALT, VK_SNAPSHOT);

wnd.onClose = function () {
UnregisterHotKey(wnd.handle, IDHOT_SNAPDESKTOP);
UnregisterHotKey(wnd.handle, IDHOT_SNAPWINDOW);
}


How can I modify this for the start button VK_LWIN (0x5B) to be blocked?

Thank you

Can Anyone help?

You can download the following sample:
http://www.swfkit.com/download/swfkit/kiosk.zip

which shows how to use the TrapKeys.dll. The TrapKeys.dll is able to block keys "CTRL+ESC", "ALT+TAB", "ALT+ESC" and "Start Menu", as well as disable the taskbar and the task manager.

The three functions exported by the TrapKeys.dll are

DisableTaskKeys(bDisable): disable "CTRL+ESC", "ALT+TAB", "ALT+ESC" and "Start Menu"
DisableTaskBar(bDisable): disable the task bar
DisableTaskMgr(bDisable): disable the task manager

All of them take one boolean parameter "bDisable". If it is set to be true, they will disable the targets; otherwise, they will enable the targets.
