Do you know how window positions are
defined ?
I need to know the 2 pushes (X and Y)
for window positions. (inverted notation or not ?)

From my course book : on window dimensions :

... The two decimal numbers that define the DIMENSIONS
of our window 64 & 472 translate into 0x40 and Ox1D8
in hexadecimal. These two parameter (40 & 1d8
dimensions) values are pushed on the stack. In
Assembly, no matter which 'higher' language is used,
no matter which compiler is used, a 'long' push is
68xxxxxxxx (with inverted notation for the xxxxxxxx
address) whilst a 'short' push is 6Axx, and therefore
we get : 68D8010000 = push 000001D8 (note the inverted
notation D801!) and 6A40 = push 00000040 ...

But there is nothing on window positions in it.

Assuming you're looking for a createwindowexa struc (the most likely api to be used), here's some info:

HWND CreateWindowEx(

DWORD dwExStyle, // extended window style
LPCTSTR lpClassName, // address of registered class name
LPCTSTR lpWindowName, // address of 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 of parent or owner window
HMENU hMenu, // handle of menu, or child-window identifier
HINSTANCE hInstance, // handle of application instance
LPVOID lpParam // address of window-creation data
);

Given that the pushing order is reversed, you're looking for push # 7 and 8.

Thanks , now I only need to know the X and Y pushes in Hex for window positions.

For window dimensions they are :
Short push (vertical) : 6A
Long push (horizontal): 68 (followed by inverted notation)

Don't really understand what u're looking for but I guess if the position<256 then short push is used, if position=>256 then long push is used.

Never had anything to do with short/long pushes but as U describe it it's just a way to save some bytes if the value of the pushed dword can be stored in one byte.

I just want to customize a child window's position with a Hex editor as is decribed in this tutorial for window dimensions :
http://www.searchlores.org/paris/paris6.htm

In case a want to move (and not resize) a window of an existing application.

If you want to do a search in a hex-editor:
Assume an x-position of 0x0215. This is a 2-byte number so it can't fit in one byte. This shall probably be a Long Push so search for 0x6815020000
Assume an x-position of 0x0020 This is a 1-byte number so it fits in one byte. This may be a short push so search fo 0x6A20

Yes ! That works. Thanks, you're a nice guy.
In fact, my target is the Opera browser that is available for free :
http://www.geocities.com/ccctournament/Opera.zip

It has an ugly black horizontal bevel line, about half the window in length, in the top right corner, next to the toolbar buttons.
Width 472 Height 4
Left 328 Top 43 (standard display settings)
But I can't find it with my Hex editor.
Please have a look at the downloadable target.

Click right on the toolbar, "Off" is disabled.
You can of course do this in the menu >History>Register and then >File>Preferences>Browser Layout.
But it would be wonderful if the whole toolbar were deleted as default. You can do all navigation with the menus and that would save much space.
