This question was posted by another person on another forum, but it is exactly the issue I'm running into also. I dont know and cant find the answer he got, but someone here at EE helped him out to success and I need the same answers. Thank You.

I'm trying to dynamically subclass a field on a property page.  The code looks like this:

  BOOL CMyPropertyPage::OnInitDialog()
  {
    CPropertyPage::OnInitDialog();
    m_myedithandler.SubclassDlgItem(IDC_TEXT,this);
    return TRUE;  
  }

The SubclassDlgItem fails on an ASSERT in

  BOOL CWnd::Attach(HWND hWndNew)
  {
    ASSERT(m_hWnd == NULL);                       //OK
    ASSERT(FromHandlePermanent(hWndNew) == NULL); //fails
    ...

I used the same override logic on an edit field in a regular dialog
without any problem.  Is there something special about subclassing
on a property page?  Or can someone point me to something else
I am doing wrong?

CrazyLee,
Howdy MS states that you can't assiciate DDX/DV with controls that you wish to subclass. That is your problem. Here is the link to the exact MSDN problem and how to solve it.  http://support.microsoft.com/support/kb/articles/Q113/4/21.asp

No I didn't get the points you have to accept my comment as an answer or I can submit an answer; if you like, so yo can explicitly accept it. Glad to be of help.

Hi,
I thought I had done it correclty, I hit accept as answer
and graded it(A+)and also tried just 'accept' and close, but have seen no feedback that it actually happened...
Be nice if they popped up a 'recieved' dialog or something.
It kept going to your info/stats page and that was it.
Thanks and let me know if it still doesnt go thru,
This is a great forum and your response was quick!

I'll just prospose an answer and see if that fixes it. That way you can just click accepts.  (Seems like we need some debugging with the EE code ;-)
