setWindowLong API.....urgent

Hi,

How do I use the SetWindowLong API to retreive my window style???

This is the syntax for the API:

Code:

---

Declare Function SetWindowLong Lib "user32.dll" Alias "SetWindowLongA" (ByVal hWnd As Long, ByVal nIndex As Long, ByVal dwNewLong As Long) As Long

---

hwnd -> handle of the window who's style i need
nIndex ->GWL_STYLE ( to get the window style)

but what about dwNewLong?? what do I pass for that argument??? the site http://www.vbapi.com mentions a callback function, but I don't know how to use it and what its for!

Any help here will be really appreciated.

Thanx.

The SetWindowLong function is only for setting Window Styles. To get Window Styles, you must use the GetWindowLong function. Information on how to use GetWindowLong can be found here: http://www.vbapi.com/ref/g/getwindowlong.html

thanx oetje,

don't now how i overlooked that!
