Whats the most straight forward way to capture and record keystrokes even
when the program does not have focus? Running in system tray as icon for
example.

You need a global keyboard hook for that. Check http://groups.google.com

Thanks Udo for the link. I have searched through all the documentation and
at least understand what I have to have to accomplish the hook, however,
through all the searching I only found examples in Delphi and VB. I have
also found out this appears to be an advanced function, so maybe I am biting
off more than I can chew, but with a decent bcb c++ example I believe I
could fiqure it out. It doesn't look like to much coding. I would need an
example of how to call the hook dll in my exe and since I have never had to
write my own dll, some kind of example of how the hook should be declared in
BCB C++. I have v5 pro. Any help would be appreciated.

And here comes the problem. I'm a Delphi pro but a C++ newbie and
although I can give you some general tips there's no way for me at the
moment to give you a working example of c++ code. Sorry.

lol. I know what ya mean. I even have Delphi v4 but have only fired it up
and looked at it. I would not even know where to start, although I believe
it is very close to c++. Anyway, thanks for your input. In the meen while I
did find some code but I can't get a portion of it to compile. I have never
tried to call a function in an exe out of a dll, but logically speaking, and
the fact it is suppose to be code that works, it looks like it should. For
anybody else out there, heres what I have.

EXE portion. I put this in an OnClick event for now because I really have no
idea what it's going to do at run time.

void __fastcall TConsoleForm::Button1Click(TObject *Sender)
{

  FARPROC  KeylogHookProc;
  HINSTANCE KeylogDLL;
  HHOOK  KeylogHook;

  KeylogDLL=LoadLibrary("Keylog.dll"); /this appears to open the dll to the
exe?
  KeylogHookProc=GetProcAddress(KeylogDLL,"KeyboardHookProc"); /this appears
to access the process I want?
  KeylogHook=SetWindowsHookEx(WH_KEYBOARD,KeyboardHookProc,KeylogDLL,NULL);
/heres where I get the error "Undefined         KeyboardHookProc"

When this compiles it says undefined KeyboardHookProc. Now I know it is not
defined in the EXE, but from the code above, I thought it would go out to
the dll and get the Proc there.

Heres the Dll.

 LRESULT CALLBACK KeyboardHookProc( int code,WPARAM key, LPARAM lParam)
{
    //Your code to log the keys goes here

    return CallNextHookEx(NULL, code, key, lParam);

So as you can see, KeyboardHookProc is defined here but is the code in the
EXE capable of checking this during compile? Do I have to add or include
something to the EXE to get it to find it? I'll keep praying for help. Udo,
maybe from this you can do some C++/Delphi converting? lol.

Actually I started reading some C++ groups, was browsing all groups,
found your subject and replied without noticing I was posting to a C++
group ;) I normally start reading tons of messages of a group before I
post there. Anyway. Glad I could help, at least guide you into the right
direction.

BTW: C++ might be a little more powerful (regarding the ability to write
drivers) but IMHO there's nothing comparable to the RAD IDE of Delphi
(so you should consider using Borland's C++ Builder to have a C++ RAD
IDE. But that's getting OT and it's only my $0.02)
