Sample Program to Enable Future Data
Using C++
The following lines of code provide a sample program to enable the
ihArchiverAllowFutureDataWrites
option using C++:void SetFutureDataWriteOptions(void)
{
ihChar enable[50];
printf("\n\n Please enter 1/0 for enable/disable future data write per data store: ");
_getws(enable);
ihChar dataStoreName[50];
printf("\n\n Please enter data store name to enable future data writes ");
_getws(dataStoreName);
ihAPIStatus Status;
ihOptionEx option;
option.Option = ihArchiverAllowFutureDataWrites;
option.DataStoreName = dataStoreName;
Status = ihArchiveSetOption(SrvHdl, &option,enable);
}
void GetFutureDataWriteOptions()
{
ihChar dataStoreName[50];
printf("\n\n Please enter the name of the Data Store Future Data write Option: ");
_getws(dataStoreName);
ihAPIStatus Status;
ihChar *Value;
ihOptionEx temp;
temp.Option = ihArchiverAllowFutureDataWrites;
temp.DataStoreName = dataStoreName;
Status = ihArchiveGetOption(SrvHdl,&temp,&Value);
printf("Archive Future Data Write Option ihArchiverAllowFutureDataWrites value is - [%ls] for the Data Store [%ls]\n", (Value ? Value : L"NULL"), dataStoreName);
Pause();
}
Using C#
The following lines of code provide a sample program to enable the
ihArchiverAllowFutureDataWrites
option using C#:static void Main(string[] args)
{

connection = ClientConnect.NewConnection;
do
{
Console.WriteLine("1 Set/Enable Data Store Create Offline Archives Option Value");
Console.WriteLine("2 Set/Enable Data Store Allow Future Data Writes Option Value");
Console.WriteLine("3 Get Data Store Create Offline Archives Option Value");
Console.WriteLine("4 Get Data Store Allow Future Data Writes Option Value");
Console.WriteLine("Enter Option Value");
swtValue = Console.ReadLine();
switch (swtValue)
{
case "1":
Console.WriteLine("Enter Data Store Name");
dsName = Console.ReadLine();
connection.IServer.SetOption(HistorianOption.ServerCreateOfflineArchives, "1", dsName);
Console.WriteLine("Option value set to " + connection.IServer.GetOption(HistorianOption.ServerCreateOfflineArchives, dsName));
Console.ReadKey();
break;
case "2":
Console.WriteLine("Enter Data Store Name");
dsName = Console.ReadLine();
connection.IServer.SetOption(HistorianOption.ArchiverAllowFutureDataWrites, "1", dsName);
Console.WriteLine("Option value set to " + connection.IServer.GetOption(HistorianOption.ArchiverAllowFutureDataWrites, dsName));
Console.ReadKey();

Console.ReadKey();
break;
case "4":
Console.WriteLine("Enter Data Store Name");
dsName = Console.ReadLine();
Console.WriteLine("Option value is: " + connection.IServer.GetOption(HistorianOption.ArchiverAllowFutureDataWrites, dsName));
Console.ReadKey();
