I am creating a static text dynamically for tab control
 
BOOL abc::OnInitDialog()
{
m_cTab.Create("live picture",1040,0,180,255,0,30,152); //item id is 1040,tabID is 0
}
In resource.h
#define IDC_IMAGE 1040
I have a button on Dialog box

void abc::bntclick()
{
HWND wnd=::GetDlgItem(m_hWnd, IDC_IMAGE);

What kind of control is m_cTab? Your Create() call parameters does not match for common CWnd derived classes. Also, why did you use the numeric value 1040 in some places and the definition IDC_IMAGE in other places? Finally, if m_cTab is the member variable of your static control, why did not use m_cTab.m_hWnd or m_cTab.GetSafeHwnd()?

viod abc::bntclick()
{
HWND wnd=::GetDlgItem(m_cTab.GetSafeHwnd(), id);
}
