NDI_VALIDATE

NDI_VALIDATE
hwndParent = (HWND)wParam;    // handle of parent dialog window

The NDI_VALIDATE message is sent when Setup sends the DIF_VALIDATECLASSDRIVERS to the network class installers. The driver installer should check that all properties are correctly set or have valid default values; if a required parameter is not known and cannot be defaulted, then the installer should prompt the user for the value.

This message has no parameters.

• The return value is zero (OK) if successful; otherwise it is a nonzero NDI error value. If the user is prompted for a value and selects cancel, it should return ERR_NDI_CANCEL.

A driver installer may call NdiProperties during this message. A driver installer that handles this message must also call NdiDefProc to perform standard validation.
