We know how to take window to foreground (SetForegroundWindow())
But how can I push the window to background and let the window which is under our application's window cover our application window?

If you known wich window is under your window, that call SetForegroundWindow for that window.

Otherwise, may be minimizing your window with ShowWindow(SW_MINIMIZE) is satisfactory?

use SetWindowPos with wndTop for the background window.

Hello
An idea is to use EnumWindows() to enumerate all top level windows, then push them all forward.

Why would you want to do this? If I am typing in some program and all of a sudden the windows started changing their z-order, that's not going to make me very happy.

how we can convert CWnd* to HWND

19-Jun-06 2:39

Basically what I want is I am copying from background window to my application few text data. WHn I want to cut the data from background window I need to switch to it I want to do it with mouse, if mouse goes to title area immediatly my background application come forward. I will copy the etxt and paste to my application. problem is I can get the effect by ShowWindow(SW_MINIMIZE) but then i can see the window going to left bottom corner visibly. which is irritating on slow machines.

Try this:

CWnd * wnd = ....;
HWND hwnd = *wnd;
// or
HWND hwnd = wnd->m_hWnd;

Yes, it works thanks to a cast operator within CWnd: "operator HWND() const;".

CWnd* pMyCwnd = new CWnd();

pMyCwnd->m_hWnd // This is the HWND of CWnd class

Too many plans make the health badly!!

you can use if you have a CWnd from m_hWnd
---------------
HWND hWnd=this->m_hWnd;

Or you do this

CWnd *pWnd // whatever window your pointing to
HWND MyHandle = (HWND) pWnd

Dear All,
I am a newbie in Visual C++. I have a project to make. That project needs to communicate with the 5 tables in the Microsoft Access. Each table is a reference for the others.
Each record contains 4 fields. I would like to guide me how I could read that tables.
Until now I try to do it with the MFC . I start a new application with database support. The wizard find in a step which give me the option to choose one of the five tables. I do not know what I am doing wrong and I cannot select all of them. May be I made some mistake may be the MFC does not supported.
I am waiting hearing from you as soon as possible.
Thanks in advance for your time.
Best Regards,
Konstantinos.

Dear All,
Thanks for your immediately response. I download the demo and I looked into the MSDN. Could you please advice me where I made the mistake? I attach the I have written. I take an error that CDatabase does not exit or undeclared variable.
Thanks for your time.
