MeteoTools::LoadAllMSDFiles

time_t LoadAllMSDFiles();

Return Value

    Nonzero if successful; otherwise 0 = no files or error.

Remarks

     
For a selction of exit meteosets you can use the MSDFile list.
    A MSDFile is a CArray-Objekt and is defined in
BMSD_Defs.h
    This is a list of all exist meteo files with the extension .msd in the meteodata directory.
    But before you use these must you load it.

Example

     // resfresh the list of exist files

   // NowDate        = GetCurrentMSDFile()    = set of last selected file
   // ExistDates     = GetMSDFileList()       = the complet file list
   // FirstSynopDate = GetFirstSynopMSDFile() = set of the first synop file
   //
MeteoDataSelection = list count of the last selected meteo view

Note: All synop files will stand above in the list. The first meteo file will come after the last synop file.
