Adding a Window to the Clipboard Viewer Chain

A window adds itself to the clipboard viewer chain by calling the SetClipboardViewer function. The return value is the handle to the next window in the chain. A window must keep track of this value — for example, by saving it in a static variable named hwndNextViewer.

The following example adds a window to the clipboard viewer chain in response to the WM_CREATE message.

case WM_CREATE: 
 
    // Add the window to the clipboard viewer chain. 
 
    hwndNextViewer = SetClipboardViewer(hwnd); 
    break;
