Dock/Anchor alternative in C++ for List Control - winapi

Question

In .NET there are Anchor & Dock properties that can make the controls responsive whenever you resize the window.
I want to do something similar with this C++ List Control. Basically I want to dock it in the dialog, so when I resize the window, it should be resizing.

Answer 1

There is no docking support in the Windows API. You'll have to implement it manually by handling the WM_SIZE message:
case WM_SIZE: {
UINT width = LOWORD(lParam);
UINT height = HIWORD(lParam);
// IDC_LIST1 will occupy the entire client area of its parent.
// Adjust as needed.
MoveWindow(GetDlgItem(hWnd, IDC_LIST1),
0, 0, width, height, TRUE);
return TRUE;
}
