What exactly are you trying to accomplish?

I want to capture screen, keys and mouse move and clicks in my and other 
applications.
So, filling a log file.
Thx

Look at SetWindowsHookEx().  You can use WH_MOUSE, WH_KEYBOARD, and 
WH_GETMESSAGE/WH_CALLWNDPROC for that.  You will have to implement your hook 
procedures inside a DLL in order to hook other applications, though.  Go to 
http://www.deja.com and search the newsgroup archives, as examples have been 
posted many times before.

Hi,

Then your code is likely buggy.  Such hooks are very low-level and very 
sensitive.  Even the slightest error in your code could blow them up badly.

Then you did not install the hook globally properly.

Works fine for me.

The deja link redirects to: http://groups.google.com/.

If that is expected, then it works.  If it is not expected, then it does not 
work.  You expected it, but the OP didn't.

That is what it is supposed to do.  Google owns Deja.  The actual archive
and search engine work fine regardless of which URL you use, though.

I've compiled a keyhook applicaton. DLL sends keys pressed to APP using:

LRESULT CALLBACK KeyHookProc(int nCode, WPARAM wParam, LPARAM lParam)
{
 if (nCode<0 || (lParam & 0x80000000) || (lParam & 0x40000000) )
  return CallNextHookEx(KeyHook, nCode, wParam, lParam);

 PostMessage(HWND_BROADCAST, MY_CUSTOM_MESSAGE, wParam, lParam);

 return CallNextHookEx(KeyHook, nCode, wParam, lParam);
}

This is how I get the posted message:

_fastcall TForm2::TForm2(TComponent* Owner) : TForm(Owner)
{
MY_CUSTOM_MESSAGE = NULL;
 FCustomMessage = "MyMessage";
 MY_CUSTOM_MESSAGE = ::RegisterWindowMessage( FCustomMessage.c_str() );
 Application->OnMessage = AppMessage;
}

void __fastcall TForm2::AppMessage( TMsg &Msg, bool &Handled )
{
 if( (Msg.message == MY_CUSTOM_MESSAGE) && (MY_CUSTOM_MESSAGE != 0) )
 {
   Handled = true;
   Label1->Caption = "wParam: " + IntToStr(Msg.wParam);
   Label2->Caption = "lParam: " + IntToStr(Msg.lParam);
   Form2->Show();
 }
}

Everything works fine when my APP is hidden or Form is not in focus, but 
when i try to press a key on my form, in edit box or anywhere, the APP 
freezes. Why is that?
