TMapUtils

 
 Constructor initializes Database host
 Database and user name

 Default destructor

 Prints information about Database settings
 HOSTNAME, DATABASE, USERNAME 

  Connecting to a Database on server specified in constructor
  and returning pointer to TSQLServer Structure...

  Connectos to DATBASE on HOSTNAME and Prints out System Names from
  table System. They correcspond to MAP names in old version of MapManager

 Prints out Subsystems and Items for Given System

 
  This function Prints content of ValueDescription table for Given Item
 specified by (System,SubSystem,Item) in Run ranges tMinRun -> tMaxRun

 NOTE. This will print all entries independent of author entry in the database

 Selects Values from Database for given Item , Run Number and author and returns 
 TSQLResult to calling function. Also makes check on type of Item.

 NOTE. If calling this function one must call it from "try"-"catch" block.
 If error accures function will trow an exception. 

  This routine initializes Integer Buffer passed to it and fills it with  
  Values for given Item. There are several advantages using this method.

  1) User does not have to warry about deleting array if it is defined
      as static. For example :
   {
       TIntBuffer  myDC_T0;
       GetMapIntBuff("DC_","t0","value",15678,&myDC_T0);
   }
   after this braket buffer will be delated automaticaly.

   2) Class TIntBuffer has bound check (unlike array of int's).
      if one will ask for non existing element in array it will not 
      couse segmentation falt.

  NOTE: It is recomended to use this function instead of 
  GetMapInt to avoid memory leaks. 
 
 

  This routine initializes Float Buffer passed to it and fills it with  
  Values for given Item. There are several advantages using this method.

  1) User does not have to warry about deleting array if it is defined
      as static. For example :
   {
       TFloatBuffer  myDC_T0;
       GetMapFloatBuff("DC_","t0","value",15678,&myDC_T0);
   }
   after this braket buffer will be delated automaticaly.

      if one will ask for non existing element in array it will not

  NOTE: It is recomended to use this function instead of 
  GetMapFloat to avoid memory leaks. 
 
 

 This routine writes into pSystem_ID system ID for given System_name

 returns 0 if system was found. -1 otherwise

  Checks if Tbale  tblname exists in database 
  returns 0 if table exists throws exception otherwise.

  SubSystem in pSubSystem_ID variable

 Returns SubSystem id from table SubSystem corresponding to given SystemID

  
 This routin finds latest ItemValueId from RunIndex table for given run number
 and returns Record of Runindex entry in tRunIndex variable.
 This is just wrapper for GetRunIndexEx routin which throws exception if 
 ItemValueId is not found. returns 0 on success, -1 otherwise.

 This routin finds latest ItemValueId from RunIndex table for given run number
 and returns Record of Runindex entry in tRunIndex variable.
