One possibility could be (calling the function inside your dialog, maybe when showing up):

CSomeDialog::SomeMethod()
{
HANDLE p_Dlg = GetDlgItem((HANDLE)this, IDC_YOURDIALOG);
//...
}

afterwards you can give the handle to be used in other place. Forget it. I choose false example from the net. Thanks for correction Stephen :)

if u have pointer of dialog, then CWnd *pWnd=NULL; HWND hWnd= m_pDlg->GetSafeHwnd(); pWnd=FromHandle(hWnd);

Are you trying to add ToolBar to a CDialog? If yes Check following articles CToolbarDialog - dialog with floating toolbar[^] http://www.codeguru.com/cpp/w-d/dislog/toolbarsandstatusbars/article.php/c1949/[^] If that is not the case please ignore my message. I hope it helps.

This code is flawed:

1. GetDlgItem's first parameter is a HWND, not a HANDLE. Your code will give a compiler error.
2. Even is the code was modified to look like the following, it would still be wrong: HWND p_Dlg = GetDlgItem((HWND)this, IDC_YOURDIALOG); Using what in this case is essentially a reinterpret_cast doesn't make a pointer a HWND. The cast just tells the compiler that although it knows a pointer isn't a HWND and would normally not normally compile code that incorrectly assumes it is, that in this case it should just shut-up and plough on.

GetDlgItem() returns a handle to a sub item within a Dialog, not to a Dialog window. It is much better to do this in the Dialog itself, when you handle the WM_INITDIALOG message.
