Why VK_RETURN not working???

This is my code

Code:

---

WNDPROC oldEditProc;

INT_PTR CALLBACK newEditProc(HWND hEdit, UINT uMsg, WPARAM wParam, LPARAM lParam) {
        switch (uMsg)
        {
        case WM_KEYDOWN:
                {
                        SendMessage(GetParent(hEdit), uMsg, wParam, lParam);
                        break;
                }
        }
        return CallWindowProc(oldEditProc, hEdit, uMsg, wParam, lParam);
}

//...

oldEditProc = (WNDPROC)SetWindowLongPtr(GetDlgItem(hDlg, IDC_EDIT1), GWLP_WNDPROC, (LONG)newEditProc);

// ...

case WM_KEYDOWN:
                {
                        switch (wParam)
                        {
                        case VK_RETURN:
                                {
                                        MessageBox(hDlg, 0, 0, 0); // I can't see this
                                        break;
                                }
                        }
                        return 0;
                }

//...

DialogBoxParam(someInstance, MAKEINTRESOURCE(IDD_DIALOG1), somehwndParent, DlgProc, NULL);

I can't see the messagebox, any ideas???

Does the edit have the ES_WANTRETURN and ES_MULTILINE styles?

Nop, is a single line edit control

I believe that you need to use WM_GETDLGCODE and return DLGC_WANTCHARS, allowing you to receive a WM_CHAR message.

I don't think edits without the ES_MULTILINE and ES_WANTRETURN send VK_RETURN msgs.

from MSDN

"ES_WANTRETURN Specifies that a carriage return be inserted when the user presses the ENTER key while entering text into a multiple-line edit control in a dialog box. Without this style, pressing the ENTER key has the same effect as pressing the dialog box’s default pushbutton. This style has no effect on a single-line edit control. "
