Instructions

In the following C++ code example, the style constant BS_COMMANDLINK specifies the button as a command link button.

HWND hwndCommandLink = CreateWindow(
    L"BUTTON",  // Predefined class; Unicode assumed
    L"",        // Text will be defined later
    WS_TABSTOP | WS_VISIBLE | WS_CHILD | BS_COMMANDLINK,  // Styles
    200,        // x position 
    10,         // y position 
    100,        // Button width
    100,        // Button height
    m_hwnd,     // Parent window
    NULL,       // No menu
    (HINSTANCE)GetWindowLong(m_hwnd, GWL_HINSTANCE), 
    NULL);      // Pointer not needed

Use the SendMessage function to set the command link label and supplementary text via the WM_SETTEXT message and the BCM_SETNOTE message, respectively.

SendMessage(hwndCommandLink, WM_SETTEXT, 0, (LPARAM)L"Command link");
SendMessage(hwndCommandLink, BCM_SETNOTE, 0, (LPARAM)L"with note");
