Retrive the handle of Picture Control

Hi,
I have a Picture control,and its ID is IDC_STATIC_SCREEN.
I want to retrive the window Handle of the Picture control.
Using MFC, I know how to do that:

Code:

---

void CLiveVideoDlg::DoDataExchange(CDataExchange* pDX)
{
  CDialog::DoDataExchange(pDX);
  //{{AFX_DATA_MAP(CLiveVideoDlg)
  DDX_Control(pDX, IDC_STATIC_SCREEN, m_staticScreen);
  //}}AFX_DATA_MAP
}
...
CStatic        m_staticScreen;
//Retrive the window Handle of the Video Screen
HWND hWnd = m_staticScreen.GetSafeHwnd() ;
...

---

But what shall do if I want to do the same thing by calling Win32 API ?
HWND hWnd = ?????;
Thank you!

just perform subclassing on this and use

m_wndPicture.SubclassWindow(GetDlgItem(IDC_PIC));

IDC_PIC is the id of your picture control.and m_WndPicture is the object of your Picture Class.

I use Win32 API to write program, not MFC.
What kind of type is m_wndPicture ?
I can't do :
HWND hScreen;
hScreen.SubclassWindow(GetDlgItem(IDC_PIC));

try this to get handle of your control
HWND hWnd = GetDlgItem(IDC_MYPIC);//id of your picture control
if you want to perform some operation extra let me your mail id.i will send you my Files to you.

GetDlgItem API function needs the handle of parent dialog of that control, as for example:

Code:

---

HWND hWnd = GetDlgItem(hWndDialog, IDC_STATIC_SCREEN);

---

BTW. Why do you not take a look in MSDN?

according to MSDN

CWindow::GetDlgItem

This method retrieves the specified child window.

The GetDlgItem method only works for immediate child controls of a dialog box—it does not search through nested dialog boxes.

HWND GetDlgItem(int nID )const;

Thank you for pointing us to CWindow::GetDlgItem, but:

• CWindow is an ATL class.
