1042  * PARAMS
1043  *
1044  *   handle        [I]  only -1 is handled currently
1045  *   id            [I]  id of the string to be loaded
1046  *   lpBuffer      [O]  buffer for the string to be written to
1047  *   nBufferMax    [I]  maximum size of the buffer in characters
1048  *   lang          [I]  the preferred language for the string
1049  *
1050  * RETURNS
1051  *
1052  *   If successful, this function returns the language id of the string loaded
1053  *   If the function fails, the function returns zero.
1054  *
1055  * NOTES
1056  *
1057  *   The type of the first parameter is unknown.  LoadString's prototype
1058  *  suggests that it might be a module handle.  I have made it an MSI handle
1059  *  for starters, as -1 is an invalid MSI handle, but not an invalid module
1060  *  handle.  Maybe strings can be stored in an MSI database somehow.
