One of my first Windows programs is to try and encapsulate the Windows code
into reusable objects (using Borland C++). I have studied the various
techniques for passing an object pointer to WndProc() so it can be put into the
cbWndExtra area via GetWindowWord/Long() PutwindowWord/Long(). Compiling the
HELLOW project that comes with BC++ works successfully. However, when I try and
stuff a pointer into the lpParam area when I do CreateWindow() (it's the last
argument) I get an Exception 13 / error 0. I cannot find Windows exceptions
documented in TFBM [where B => Borland and M => manual + online documentation;
however, I have not yet purchased the MS Programmer's Guide to Windows 3.0
yet]. Cany anyone tell me what this means and where to find the reference for
myself? Also, when I substitute NULL for the last argument the call succeeds.
