Hi
yes, before calling the domodal fr any dialog destroy the previous one by using EndDialog.

But I would suggest you implement the child dialog concept. So that when you close the first dialog you will not get he flickering effect. adn there you willnot face problem for closing and switching betwen the dialogs.

   Keep it simple - open both (the 2nd and 3rd) from the 1st dialog. When the second dialog is closed it will return a value indicating what button/command was used to close it.

   So you can, for example, open the third dialog if the second one returned IDOK.

   Peace!

To close a modal dialog, simply call EndDialog().

Can I add a new interface to existing activex control. I want to add new methods and adding them under current interface seems to be dangerous. I want to add then under new interface. Any help on it ?

Add new functionality to an ActiveX control by adding a new interface is the norm.

Can you be more specific? Do you have the source? Is it written with ATL, MFC, straight C/C++ or some other framework?

How to make an owner drwan Picture Box in ATL ( not using MFC support). My aim to make the picture transparent in the dialog.

I am using ATL composite control dialog. But in the Picture Control, there is no Owner draw property listed in Property Window. I manuall modified rc file and add SS_OWNERDRAW, But i am not gettiing the WM_DRAWITEM message....
I did try to set owner draw
::SetWindowLong( ::GetDlgItem( m_hWnd, IDC_STATIC_PIC ), GWL_STYLE, (::GetWindowLong(::GetDlgItem( m_hWnd, IDC_STATIC_PIC ), GWL_STYLE ) )| SS_OWNERDRAW );

also by SendDlgItemMessage()

Since the I am not getting WM_DRAWITEM to my ATL dialog, i cant do anything to make picture box the transparent.

Any suggestion , code are welcome
Thanks

Well, you could start by searching MSDN for the registry functions, or you could search CP for a registry helper/tutorial/library. Then maybe you could start reading what you find and learn how to use the registry.

What you are asking is very easy, a little too easy infact.

You can use RegEnumKeyEx to enumerate subkeys.
Use RegEnumValue to enumerate the values of a specific key.
Use RegNotifyChangeKeyValue for change notification.

Yes I found the answer to my LNK1169 thanks to the help of some better experienced forum users. Though I don't see how this relates to the OP's question.

OK, granted, the question may be a little difficult for some people. After all you need to be a brain surgeon to type in 'registry' to the MSDN search box. I stand by my answer in that the OP should search before posting, which if he had done he could either have tried the function and asked for help with his errors, or simply state that he does not understand them.

If you re-read my LNK1169 thread, I think you will find I had stated exactly what I had coded, how I had tried to fix and that I still couldn't understand why, hence my post. I did not simply write "I have a link error how can I fix it?".

Handle EN_CHANGE message for your edit box in your appplication..for reteriving value from edit box using GetWindowText api, based on it value either append it in location box using GetWindowText and SetWindowText or Disable the Edit Box using EnableWindow(...) if empty value has been entered
