- wParam [in]
An int that specifies the ID of the button to be clicked.
- lParam [in]
Must be zero.
The return value is ignored.
The button ID specified by wParam is sent to the TaskDialogCallbackProc callback function as part of a TDN_BUTTON_CLICKED notification code. After the callback function returns, the task dialog is closed if S_OK was returned from the callback function. If S_FALSE was returned from the callback function, the task dialog remains active.
