how to move button when the dialog is resized?

But not run

Crash or not moving the controls in the good position ? When doing something like that, moving controls around, I play dumb and use the dialog client area rectangle (GetClientRect). Play around with the values to move to the bottom of the rect returned by GetClientRect; Note: be careful with the coordinate being in either relative to the client or window .

Watched code never compiles.

Not moving the controls in the good position. I dont know how to use this function. Maybe on this way:

void CEjemplo::OnSize(UINT nType, int cx, int cy)
{
CDialogEx::OnSize(nType, cx, cy);
CRect myRect;
GetClientRect(&myRect);

    if (GetDlgItem(IDC\_EDIT1))
    {
         m\_Edit.MoveWindow(5,5,cx-55,cy-55); //puedes jugar con estos valores
          m\_Button1.MoveWindow(myRect.right, myRect.bottom,
  myRect.Width(), myRect.Height());

    }

}

But I dont want to change the size, only the position. I'd like to move at the right botton corner.

use SetWindowPos (with the SWP_NOSIZE option, check the documentation ) function instead of MoveWindow. M.

I've tried with this:

void CEjemplo::OnSize(UINT nType, int cx, int cy)
{
CDialogEx::OnSize(nType, cx, cy);
CRect myRect;
const CWnd &p=wndBottom;
GetClientRect(&myRect);

    if (GetDlgItem(IDC\_EDIT1))
    {
        GetDlgItem(IDC\_EDIT1)->MoveWindow(5,5,cx-50,cy-80);  //puedes jugar con estos valores
        m\_Button1.SetWindowPos(&p,5,5,cx-50,cy-75,SWP\_NOSIZE);
    }

}

But when I run the application it crash X|

Exception thrown? Assertion fired? Have you stepped into the code to see what is actually going on?

change this to read:

m_Button1.SetWindowPos(&wndTop, cx - m_Button1.Width - 5, cy - m_Button1.Height - 5, 0, 0, SWP_NOSIZE);

Now, when I maximized the dialog the button dont move itself...

See if the Extras section of this article is of any help. I've updated the code in a newer project but the premise is the same.

I'm sorry , the error wasn't due to the setwindowspos. I solved the error. It run well, but I need know the coordinates of the right bottom corner.

+5. Good bit of code.

I cant change this, becouse CButton don't have some member "width" and "Height"

[Chuck OToole]

The first two arguments to MoveWindow are the new X and Y coordinates of the upper left of the window. You are putting all your things at [5,5], on top of one another. No wonder it doesn't seem to work.

[Chuck OToole]

A CButton is a Window, WIndows have Rect (GetWindowRect() function). Rect gives you height and width. So it's not a straightforward as posted but easily obtainable.

[TheGreatAndPowerfulOz]

Sorry, the other poster is right. Use

CRect rect;
m_Button1.GetWindowRect(&rect)
rect.Width()
rect.Height()

Assuming the coordinate system is correct (Client View, Control View, Screen View), which is a big assumption at this point, the line

m_Button1.MoveWindow(myRect.right, myRect.bottom,

seems to want to put the left edge of the button at the right edge of the main window, therefore, it's not visible since it's off the right side of the main window. Similarly for the y coordinate, you're putting the top of the button starting at the bottom of the window, therefore it's outside the viewing area
