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

Something like:

void CMyDialog::DoDataExchange(CDataExchange* pDX)
{
    CDialog::DoDataExchange(pDX);
    //{{AFX_DATA_MAP(CMyDialog)
    DDX_Control(pDX, IDC_EDIT, m_edit);
    DDX_Control(pDX, IDOK, m_ok);
    //}}AFX_DATA_MAP
}
 
BEGIN_MESSAGE_MAP(CMyDialog, CDialog)
    //{{AFX_MSG_MAP(CMyDialog)
    ON_EN_CHANGE(IDC_EDIT, OnChange)
    //}}AFX_MSG_MAP
END_MESSAGE_MAP()
 
void CMyDialog::OnChange() 
{
    m_ok.EnableWindow(m_edit.GetWindowTextLength() > 0);
}

You should not be using a CString object for an edit control. Use CEdit instead.

I am getting this error "'GetWindowTextLengthA' : is not a member of 'CString'"

u suggested Cedit instead of Cstring for edit box but when i go to class wizard and then to member variable name i only have cstring as variable type option apart from int, bool etc. theres no option Cedit. what should i do?

Change the Category from Value to Control.
