If appropriate, File Manager will post error messages whenever an error is reported by a network driver function. If the error value is WN_NET_ERROR, the WNetGetError and WNetGetErrorText functions will be called to allow the network driver to return a network specific error. If these two functions fail or are not implemented, a generic message will be used instead. This behavior will be standardized across all File Manager components. Some functions, such as connection dialogs, are allowed to post their own messages as part of processing the dialog box. File Manager never posts error messages if the return value is WN_SUCCESS, WN_CANCEL, or WN_CONTINUE unless otherwise noted.
