CallWndProc hook not receiving all messages

I am making a little tool like Displayfusion and I need some Hooks to receive messages when Windows move/activate/etc , however I'm stuck..

I am using this project for the CallWndProc hook: http://www.codeproject.com/KB/system/WilsonSystemGlobalHooks.aspx

For pretty much all windows it works great(x86 and x64), however on some windows it seems to can't inject the hook DLL. Currently I am having problems with adobe reader X. No messages are being received from that window. I think it has something to do with the sandbox? Can somebody give me a push in the right direction?

The initialization code for the hook:

bool InitializeCallWndProcHook(int threadID, HWND destination)
{
  if (g_appInstance == NULL)
    return false;

  if (GetProp(GetDesktopWindow(), "WILSON_HOOK_HWND_CALLWNDPROC") != NULL)
    SendNotifyMessage((HWND)GetProp(GetDesktopWindow(), "WILSON_HOOK_HWND_CALLWNDPROC"), RegisterWindowMessage("WILSON_HOOK_CALLWNDPROC_REPLACED"), 0, 0);

 开发者_高级运维 SetProp(GetDesktopWindow(), "WILSON_HOOK_HWND_CALLWNDPROC", destination);
  hookCallWndProc = SetWindowsHookEx(WH_CALLWNDPROC, (HOOKPROC)CallWndProcHookCallback, g_appInstance, threadID);

  return hookCallWndProc != NULL;
}

Hmm, try if Spy++ can catch the messages. If it can, then obviously it's not a problem with security measures. It Spy++ can't however, then it's pretty much impossible.

See if this works: Use both WH_CALLWNDPROC and WH_GETMESSAGE hooks, since apparently, the former only catches sent message, and the latter only catches posted messages.

I have a similar Problem in my application. Visit the following link:

Strange behaviour of windows hooks

My guess ist that an application interrupts the filter function chain by not calling the CallNextHookEx method. Note that is this only possible when you are using WH_CBT hooks.
