Hi,
Can you give me a piece of code which give me the HWND of the current
console window given by default by Adagide in the Gnat environment
with the only add-on called "Win32ADA", please.
Thank you ! Bye !

from the MSDN
<http://support.microsoft.com/default.aspx?scid=kb;en-us;124103>:
"It may be useful to manipulate a window associated with a console
application. The Win32 API provides no direct method for obtaining the
window handle associated with a console application. However, you can
obtain the window handle by calling FindWindow(). This function
retrieves a window handle based on a class name or window name. "
IMHO, the method they describe in the article is risky. i can think of
2 other methods to get the HWND but they are risky as well !
OTOH, i can't see anything useful in retrieving the HWND of a console
application... may we have more information on the purpose of this
request ?

WinBase.GetStdHandle( WinBase.STD_OUTPUT_HANDLE )
Sample code:
PROCEDURE CursorPosnTIF( row, col : Natural ) IS
result : Win32.BOOL;
toRow : Natural := Natural'MAX( row, 1 );
toCol : Natural := Natural'MAX( col, 1 );
BEGIN
result := WinCon.SetConsoleCursorPosition(
WinBase.GetStdHandle( WinBase.STD_OUTPUT_HANDLE ),
WinCon.COORD'( X => Win32.Short( toCol - 1 ),
y => Win32.Short( toRow - 1 ) ) );
END CursorPosnTIF;
Note: This only works for the console window.

this does not return a WINDOW handle (HWND) but a DEVICE handle. the
return value of this function cannot be used in function taking a HWND
as a parameter.

Then try "GetConsoleWindow" defined in Kernel32.lib.
Requires W2K or XP.
In the SDK documentation:
HWND GetConsoleWindow(void);
The GetConsoleWindow function retrieves the window handle used by the
console associated with the calling process.
