Do not change size of dialog box^ too many problems. Use list control with scroll bars or etc.

Solution 1

For programmatiaclly change the window size you may use CWnd::SetWindowPos[^] method.
The OnSize event handler is called by the framework after the window's size changed. You may use it to accordingly resize dialog child controls.

// Resize the Dialog
Report reportDlg(AfxGetMainWnd()) ;
CRect rect10 ;
CWnd *pWnd1 = reportDlg.GetDlgItem(IDD_REPORT);

// CWnd *pWnd = GetDlgItem(IDD_REPORT) ;
pWnd1->GetWindowRect(&rect10);
ScreenToClient(&rect10);
pWnd1->SetWindowPos(NULL, 0, 0, rect10.Width(), rect8.bottom, SWP_NOMOVE |SWP_NOZORDER | SWP_NOACTIVATE );

I use this code for Dialog for resize as per content, still it not work. Please suggest any idea.

Solution 2

calculate the control position when the application is started.

according to that maintain same length between controls.

for example:
CRect rc;
GetDlgItem(IDC_EDIT)->GetWindowRect(&rc);

height = rc.Height();
width = rc.Width();

rc.top = rcDlg.top ;
rc.bottom = rc.top + height;
rc.left = center_position - width ;
rc.right = rc.left +width;

GetDlgItem(IDC_EDIT)->MoveWindow(rc);
