SDK Programming

[Semen Matusovski]

what am I doing wrong
A lot. First of all, dwStyle and dwExstyle fields in CreateWindowEx.

HWND CreateWindowEx(
  DWORD dwExStyle,      // extended window style
  LPCTSTR lpClassName,  // registered class name
  LPCTSTR lpWindowName, // window name
  DWORD dwStyle,        // window style
  int x,                // horizontal position of window
  int y,                // vertical position of window
  int nWidth,           // window width
  int nHeight,          // window height
  HWND hWndParent,      // handle to parent or owner window
  HMENU hMenu,          // menu handle or child identifier
  HINSTANCE hInstance,  // handle to application instance
  LPVOID lpParam        // window-creation data
);

There are nice SDK samples from Petzold's book http://www.powerbasic.com/files/pub/pbwin/petzold.zip

I'm trying to learn SDK programming with PB/DLL 6.0 Can someone
post a very basic example. I'm wanting to do something like this:

Create a form with a button and a listbox and a textbox
when the person clicks on the button it adds the valud of the
textbox to the listbox.

I already know about all the sendmessage values etc, I just
don't know how to set everything up. I took at look at
skelton.bas in the samples directory but it uses a resource
script for the dialog. I'm wanting to make the controls by
hand.

Thanks
