Well you've got to design a layout manager. Just like the ones you find in Java. ;) The best place to trigger a layout is
WM_SIZE.

There is no need to design a layout manager. You just have to resize the dialog box controls as follows. 1. Get the Client rectangle of the Dialog Box. ( Use: GetClientRect(LPRECT)) 2. Calculate the new size of controls. 4. Validate whether the dialog controls are valid window ( Use; IsWindow( HWND )) 5. Move dialog controls to the new position i they are valid windows. Hope it is useful Thank You Regards, Benoy Bose

Which is what the layout manager will do for you. :|

Layout manager in Java ( Like you said ) will automatically resize the controls in the window. Since we have a very simple method to resize the controls in MFC, designing a layout manager is overhead to the developer. In Java it's depends upon the personel interest since there are both the features are readly available.

Not always. It depends on the way you design it.

Now imagine she want's to change the layout! Imagine the overhead.

That is why you must have a layout manager. When you design, generalize your design. That is what OOP is all about. If you don't want any layout don't call the layout manager. I love the Java layout manager classes. :)

its really depends upon the persnel interest. I respect you interest. I believe Layout can generalize the functionality, but my code do the same in simple and a few lines. While I was working with layout managers in Java, i feel i have only a less freedom to move the control over the window. And I satrted to put NULL in the Java Window layout and moved my controls independently.

How can i resize the dialog box controls when i resize the dialog box??:confused:
you can use WM_SIZE and use functions MoveWindow or SetWindowPos in this event_**

But how can i do this? is there any function for this?? Thanks for reply.

Then that is called a simple layout manager. Don't get overrawed by the term Layout Manager. :)

I worked in Java for sometime. The
LayoutManagerswere cool. Some of them were not that good but then they all had some purpose as indicated by their name. I worked in someMFClayout managers. All of them were real cool. Except for setting them up. Once that pain is over it looks real cool. But as you said it depends. :)

It should be easy to find one. Hey CP has one for sure I think I saw one. :~ Of course WhiteSky has mentioned two. But they work on a single control. But the above mentioned technique can take a bunch of controls and resize them as your specify. I think I saw one or two or three... of those layout managers in Code Project. Please check.

I Even want to increase/decrease the size of the controls based on th ewindow size. How can i do this?? :((

You can either use Layout Managers or simple use MoveWindow or SetWindowPos in OnSize( WM_SIZE )

Layout Managers Found In CP[^]. You should try to search first. :|

I am not getting it. This is what my code is: void CEgAppDlg::OnSize(UINT nType, int cx, int cy) { CDialog::OnSize(nType, cx, cy); // TODO: Add your message handler code here CRect wRect,eRect; GetClientRect(wRect); m_edit.GetClientRect(eRect); POINT * pt; pt->x=eRect.left; pt->y=eRect.top; ::ClientToScreen(m_edit.m_hWnd,pt); eRect.bottom+=30; eRect.right+=30; ::MoveWindow(m_edit.m_hWnd,pt->x,pt->y,eRect.Width(), eRect.Height(),TRUE); } I am getting an Exception:((

Either Subclass the control to handle the Dialog resize or use MoveWindow api!

Hey, just reduce the code lines do as follows void CEgAppDlg::OnSize(UINT nType, int cx, int cy) { CDialog::OnSize(nType, cx, cy); CRect ClientRect( 0, 0, 0, 0 ); GetClientRect( ClientRect ); if( FALSE != IsWindow( m_edit.GetSafeHwnd())) { m_edit.MoveWindow( ClientRect ); } } This code is expected to work only when the Dialog is forcely resize by using Minimize, Maximize, Drag Size etc. To resize the control in Initial state you have to put some similiar code in the OnInitDialog of the dialog class like CRect ClientRect( 0, 0, 0, 0 ); GetClientRect( ClientRect ); m_edit.MoveWindow( ClientRect ); In OnInitDialog you do not have to check the Window handle because OnInitDialog is called after the creation of the Dialog Box and it's control. But you should check the Validity of m_edit window in OnSize because it is called by the framework when the DialogBox alone is created, before the edit is created. OK ? Regards, Benoy Bose
