Use what you want to IRV and I'll use something better than Win32lib.

1. Can you currently write the app I produced using Win32lib?
     * and it be smaller in code
     * faster in executing
     * easier to read

Hell No!

Im running this on Win98 and it doesnt crash with me.

I didnt test this extensively, I put it together in 20 minutes what do you
expect?

I did do this rather fast so there are some obvious errors in the code.
I did find lastnight after I sent the program in to Rob two instances where
atoms were
declared when they should be sequences. The point being I did this in 20
minutes.
Sure most of the code already existed in my arsinal so I just cut and pasted the
code.

I can fix this and make the program much smaller IRV believe me (the code and
the .exe)

consider this, when I use something like (below routine) I can create Windows or
Controls with one line of code
Just like Win32lib, Just like Delphi or even MASM32 which is my prefered ASM,
BTW!

I have control over the code is my point, I dont have to rely on Derek or Matt
all of the time for tips,
tricks or fixes....anyone who is frustrated that Win32lib isnt progressing
fast enough should probably start reading because in the time it takes to read
the SDK, learn API and
program something like what I sent in they will have surpassed Win32lib
capabilties.

global function CreateWindow(atom dwExStyle, object ClassName, object
WindowName, atom dwStyle,
integer x, integer y, integer Width, integer
                             Height, atom Parent, atom Mnu,
                             atom Instance, integer void)

atom classname, windowname, id

  if atom(ClassName) then
  classname = ClassName
  else
  classname = allocate_string(ClassName)
  end if

  if atom(WindowName) then
  windowname = WindowName
  else
  windowname = allocate_string(WindowName)
  end if

id =
  c_func(xCreateWindow,{dwExStyle,classname,windowname,dwStyle,x,y,Width,Height,Parent,Mnu,Instance,void})

  free(classname)
  free(windowname)

  return id
end function


I'll fix the program today when I have time... and add some error checking

Who do you think writes the abstractions to eliminate the tedium? ? ?

I've used win32lib in the past but I became frustrated about bugs and the amount
of code it contains, the speed and just about every aspect of the library.
I drained it, stretched it to it's limits but it just wasnt then and never will
be enough!
