I need to create a button dynamically in mfc dialog form by using following code..

CButton myButton1, myButton2, myButton3, myButton4;

myButton1.Create(_T("My button"), WS_CHILD|WS_VISIBLE|BS_PUSHBUTTON,
CRect(10,10,100,30), pParentWnd, 1);

In this code i got an error pParentwnd as not a member.. how can i clear this error?

You may just pass this (that is the pointer to the CDialog itself) instead of pParentWnd.

[Update]
Please note myButton shouldn't be a local variable (it should be a class member).
I used the following code in the about dialog of a MFC SDI application:

C++

class CAboutDlg : public CDialog
{
  CButton myButton;
//...

C++

BOOL CAboutDlg::OnInitDialog()
{
  CDialog::OnInitDialog();
  myButton.Create(_T("My button"), WS_CHILD|WS_VISIBLE|BS_PUSHBUTTON,
  CRect(10,10,100,30), this, 1);
  return TRUE;  
}

It is working fine (it shows the button).

That is irrelevant: I used the code inside a dialog, after all. Make sure your button variable is a member of the (dialog) class.
