Help with Keyboard Hook

My requirement is a program which will :

1. Set up a system wide keyboard hook.
2. Launch Internet Explorer in a new process (and have the hook disable some keyboard navigation hotkeys).
3. Wait for IE to finish and remove keyboard hook.

At present, if I :

1. Set up the keyboard hook (using code below).
2. "Manually" start IE from desktop

Then the keyboard hook is in place, all is well.

The problem is that if I programmatically launch ie in a new process from the same program which set the keyboard hook, the hook does not work.

The keyboard hook code is in a dll, which includes the following code :

#pragma comment(linker, "-section:.shared,rws")
#pragma data_seg(".shared")
HHOOK kbHook = NULL;  // Keyboard hook
#pragma data_seg()

LRESULT CALLBACK LowLevelKeyboardProc(int nCode, WPARAM wParam, LPARAM lParam)
{
    PKBDLLHOOKSTRUCT p;
    if (nCode == HC_ACTION)
    {
        p = (PKBDLLHOOKSTRUCT) lParam;
        if (
            // Ctrl-A
            ((p->vkCode == 'A') && ((GetAsyncKeyState(VK_CONTROL) & 0x8000) != 0)))
            return 1;
   }
                   
   return CallNextHookEx(kbHook, nCode, wParam, lParam);
}

int DLL_EXP_IMP WINAPI Set_Keyboard_Hook(BOOL bEnableDisable)
{
     if (!bEnableDisable) {
          if (!kbHook) {
               kbHook  = SetWindowsHookEx(WH_KEYBOARD_LL, LowLevelKeyboardProc, hInst, 0);
               if (!kbHook)
                    return 0;
               }
     } else {
          UnhookWindowsHookEx(kbHook);
          kbHook = NULL;
     }

     return 1;
}


The calling code calls

Set_Keyboard_Hook(flag);

to install or uninstall the hook. I am using

StartProcess("default", "C:\\Program Files\\Internet Explorer\\iexplore.exe");

to launch ie, where the start process code is :
BOOL StartProcess(char *szDesktopName, char *szPath)
{
    STARTUPINFO         si;
    PROCESS_INFORMATION pi;

    // Zero these structs
    ZeroMemory(&si, sizeof(si));
    si.cb = sizeof(si);
    si.lpTitle = szDesktopName;
    si.lpDesktop = szDesktopName;
    ZeroMemory(&pi, sizeof(pi));

    // Start the child process
    if (!CreateProcess(NULL, szPath,  NULL, NULL, FALSE, 0, NULL, NULL, &si, &pi)) {
        return FALSE;
    }

    // Wait until process exits
    WaitForSingleObject(pi.hProcess, INFINITE);

    // Close process and thread handles
    CloseHandle(pi.hProcess);
    CloseHandle(pi.hThread);

    return TRUE;
}

Is what I want to do possible, and if so how do I do it. Thanks in advance.Start Free Trial
