+/******************************************************************
+ *  MsiLoadStringW            [MSI.@]
+ *
+ * Loads a string from MSI's string resources.
+ *
+ * PARAMS
+ *
+ *   handle        [I]  only -1 is handled currently
+ *   id            [I]  id of the string to be loaded
+ *   lpBuffer      [O]  buffer for the string to be written to
+ *   nBufferMax    [I]  maximum size of the buffer in characters
+ *   lang          [I]  the prefered language for the string
+ *
+ * RETURNS
+ *
+ *   If successful, this function returns the language id of the string loaded
+ *   If the function fails, the function returns zero.
+ *
+ * NOTES
+ *
+ *   The type of the first parameter is unknown.  LoadString's prototype
+ *  suggests that it might be a module handle.  I have made it an MSI handle
+ *  for starters, as -1 is an invalid MSI handle, but not an invalid module
+ *  handle.  Maybe strings can be stored in an MSI database somehow.
