2)SetWindowPos

as i know it is a winAPI methods, but it is work fine on c# and VisualBasic. what about as?

What do you want to do that you can't do with my http://www.b4x.com/forum/additional-libraries/5116-windowmessage-library.html#post29872. That uses SetWindowLong to install a new WindowProc and then gives your Basic4ppc code access to window messages which is what installing your own wndproc would do. Also what functionality of SetWindowPos do you need?

 

[Byak@]

GetWindowLong and SetWindowLong i'm need for hide my (and not only my) window from alt+tab.yes,i can use a borderstyle=5 and recreate a window rectangle but i can't get a size of window's border(this value return a null) and using SetWindowLong is more comfortable =)
SetWindowPose i'm need for placing my app on a desctop (it will be visible only on desctop)

You can only use SetWindowLong to change the wndproc of windows belonging to the main thread of your application - not other windows so I would have thought whatever you would do with SetWindowLong you could do with my messages library.

You can get and set the position of a form on the screen using the undocumented Left and Top properties or use the Door library and the Form Left and Top properties.

You can get the actual size of a form using the Door library and the Form Width and Height properties. The Basic4ppc similarly named properties return the size of the client area, subtraction gives you the border width if you need it.

Andrew you don't understand me))
1) witj SetWindowLong a can do

[COLOR=#0000FF]private const int[/COLOR] GWL_EXSTYLE = -20;
[COLOR=#0000FF]private const int[/COLOR] WS_EX_TOOLWINDOW = 0x00000080;

[COLOR=#0000FF]public static void[/COLOR] HideFromAltTab([COLOR=#5F9EA0]IntPtr[/COLOR] Handle)
{
    SetWindowLong(Handle,
                  GWL_EXSTYLE,
                  GetWindowLong(Handle, GWL_EXSTYLE) | WS_EX_TOOLWINDOW);
}

2) i want change parent of window in Z-order

[COLOR=#0000FF]public static extern bool[/COLOR] SetWindowPos([COLOR=#0000FF]int[/COLOR] hWnd, [COLOR=#0000FF]int[/COLOR] hWndInsertAfter, [COLOR=#0000FF]int[/COLOR] X, [COLOR=#0000FF]int[/COLOR] Y,
    [COLOR=#0000FF]int[/COLOR] cx, [COLOR=#0000FF]int[/COLOR] cy, [COLOR=#0000FF]uint[/COLOR] uFlags);

[COLOR=#0000FF]public const int[/COLOR] HWND_BOTTOM = 0x1;
[COLOR=#0000FF]public const uint[/COLOR] SWP_NOSIZE = 0x1;
[COLOR=#0000FF]public const uint[/COLOR] SWP_NOMOVE = 0x2;
[COLOR=#0000FF]public const uint[/COLOR] SWP_SHOWWINDOW = 0x40;

[COLOR=#0000FF]private void[/COLOR] ShoveToBackground()
{
    SetWindowPos(([COLOR=#0000FF]int[/COLOR])[COLOR=#0000FF]this[/COLOR].Handle, HWND_BOTTOM, 0, 0, 0, 0, SWP_NOMOVE |
        SWP_NOSIZE | SWP_SHOWWINDOW);
}

Sorry, I did misunderstand. As you are working on the desktop why don't you install the free Visual C# 2010 Express and write your own libraries. You can build .NET 2.0 libraries with it that will work fine on the desktop with Basic4ppc though you can't build device ibraries.
