I have used a commandbutton in a main window where OnClick function is written
as ShowWindow(SW_SHOWMAXIMIZED); is used.
The problem is that only the edges of the window increases but i want the tools inside the window also change size to fill the maximized window.

C++

void CDemoDlg::ClickMaximize()
{
ShowWindow(SW_SHOWMAXIMIZED);
}

Solution 1

Create a command handler for the WM_SIZE message. You should be able to do this with the wizard.

In that handler:
1. Check to make sure you have a valid windows handle for at least one of your controls. The first time WM_SIZE is called, you have invalid handles. If this happens, just return.

2. Call GetClientRect() in your dialog to get the dimensions of the inside of the window.

3. Call MoveWindow() for each control to place them in a new size and position.

How you calculate the new positions will depend on how you want them to look.

If you want to position the control relative to existing controls, you can call GetWindowRect(), then ScreenToClient() to get the client based window position of the reference control.

If you get flicker on the controls, you can call LockWindowUpdate() before and after your resizing code to block repaints while the resizing is done.

This will give you a dialog that will adjust the controls dynamically as you resize it.

first step is fine but next steps i am not getting

i want to know what to include in movewindow()

You'll need to calculate where you want the control to appear.

The pass those coordinates to MoveWindow().

I can't tell you where you want the control to appear.

What I do for instance, if I have controls in a column, I'll place each subsequent control's CRect::top member to the previous control's, CRect::bottom + VerticalMargin. The value you set for Vertical margin will be a stylistic decision.

void CDemoDlg::OnLButtonDown(UINT nFlags, CPoint point)
{
// TODO: Add your message handler code here and/or call default

CRect myRect;
GetWindowRect( &myRect);
//save current cursor coordinate
GetCursorPos(&point);
ScreenToClient(&point);
SendMessage(WM_NCLBUTTONDOWN, HTCAPTION, NULL);
//__super::OnLButtonDown(nFlags, point);
}

void CDemoDlg::OnMouseMove(UINT nFlags, CPoint point)
{
// TODO: Add your message handler code here and/or call default

CRect myRect;
GetWindowRect( &myRect);
CPoint curpoint;
GetCursorPos(&curpoint);
{
MoveWindow(curpoint.x - point.x, curpoint.y - point.y,
myRect.right - myRect.left, myRect.bottom - myRect.top, TRUE);
}
}

The above code allows me to move but when its moved more i am not able to see backgrounds What correction is needed for above

I'm not sure why you're using the cursor position. It doesn't really fit you original question.

Repositioning the controls should be done inside the WM_SIZE handler.

If you goal is to move the controls using the mouse, then you may need to call Invalidate and UpdateWindow on the dialog.

I've never seen a problem with the background not getting updated, so maybe the problem is in what handler you're doing this?

sorry i have placed the code for move window above.
I had put background picture using paint then replaced with picturectrl solved the problem of background disappearing.
The proper code is
in solution 2 for move window.

Now I need the solution for maximising window.

chaiein 30-Mar-12 2:38am

I solved the moving window problem. But maximising window is confusing. I have used the method as in link below
but Its not working well because the tools gets disappered.

Please help to solve the above problem or get me new solution

C++

void CDemoDlg::OnLButtonDown(UINT nFlags, CPoint point)
{
	// TODO: Add your message handler code here and/or call default

	 CRect myRect;
	 GetWindowRect(&myRect);
              //save current cursor coordinate
		GetCursorPos(&point);
		//ScreenToClient(&point);
		SendMessage(WM_NCLBUTTONDOWN, HTCAPTION, 0);
	__super::OnLButtonDown(nFlags, point);
}

void CDemoDlg::OnMouseMove(UINT nFlags, CPoint point)
{
	// TODO: Add your message handler code here and/or call default

	CRect myRect;
	 GetWindowRect( &myRect);
	 CPoint curpoint;
	 GetCursorPos(&curpoint);
     {     
           MoveWindow(curpoint.x - point.x, curpoint.y - point.y, 
			myRect.right - myRect.left, myRect.bottom - myRect.top, TRUE);
     }
	
	 __super::OnMouseMove(nFlags, point);
}

This solved my problem of moving window
