Mechsoft.MFiles.VAF.Workers 3.0.2

Workers for M-Files Background Operations

Manages and simplifies M-Files background operations

Dependencies

• Interop.MFilesAPI

• MFiles.VAF.2.1.0.4

Samples

• Sample for running background worker at specified time once a day

public class TCMBCurrencyRateFetcher : BackgroundWorkerOnceADayWithReturn<VaultApplication, Dictionary<string, double>>
{
 public TCMBCurrencyRateFetcher() : base("TCMB daily currency rate fetcher", 16, 32, 00)
 {
 
 }

 public override Dictionary<string, double> DoWork(VaultApplication application, BackgroundOperation operation)
 {
 var serializer = new XmlSerializer(typeof(CurrenyCollection));

 using (var client = new WebClient())
 {
 using (var stream = client.OpenRead("http://www.tcmb.gov.tr/kurlar/today.xml"))
 {
 var root = (CurrenyCollection)serializer.Deserialize(stream);

 return root.Currencies.ToDictionary(d => d.CurrencyCode, d => double.Parse(d.ForexBuying.Replace('.', ',')));
 }
 }
 }

 [XmlRoot(ElementName = "Currency")]
 public class Currency
 {
 [XmlElement(ElementName = "CurrencyName")]
 public string CurrencyName { get; set; }

 [XmlElement(ElementName = "ForexBuying")]
 public string ForexBuying { get; set; }

 [XmlElement(ElementName = "ForexSelling")]
 public string ForexSelling { get; set; }

 [XmlElement(ElementName = "BanknoteBuying")]
 public string BanknoteBuying { get; set; }

 [XmlElement(ElementName = "BanknoteSelling")]
 public string BanknoteSelling { get; set; }

 [XmlElement(ElementName = "CrossRateUSD")]
 public string CrossRateUSD { get; set; }

 [XmlElement(ElementName = "CrossRateOther")]
 public string CrossRateOther { get; set; }

 [XmlAttribute(AttributeName = "CrossOrder")]
 public string CrossOrder { get; set; }

 [XmlAttribute(AttributeName = "CurrencyCode")]
 public string CurrencyCode { get; set; }
 }

 [XmlRoot(ElementName = "Tarih_Date")]
 public class CurrenyCollection
 {
 [XmlElement(ElementName = "Currency")]
 public List<Currency> Currencies { get; set; }
 }
}

Then use it in VaultApplication class

public class VaultApplication : VaultApplicationBase
{
 protected override void StartApplication()
 {
 var currencyFetcher = new TCMBExchangeRateFetcher();

 currencyFetcher.Successed += (sender, currencies) =>
 {
 var usd = currencies["USD"];

 SysUtils.ReportInfoToEventLog($"USD: {usd}");
 };

 currencyFetcher.ErrorOccured += (sender, exception) =>
 {
 SysUtils.ReportErrorToEventLog("An error occured while fetching currencies. Worker will re-run after specified timespan offset", exception);
 };

 this.StartWorker(currencyFetcher);
 }
}
