the example shown in limitFunction with a parameter of type date to insert the value of this parameter is the current date


There limitFunction](fo_limit-function.html) (class ICSSoft.STORMNET.FunctionalLanguage.Function) with parameter @date. How is this parameter to substitute the current date?


Let limitFunction set function with a parameter @date:

ExternalLangDef externalLangDef = ExternalLangDef.LanguageDef;
 ICSSoft.STORMNET.FunctionalLanguage.Function limitFunction = externalLangDef.GetFunction(
   new ParameterDef(Date, externalLangDef.DateTimeType, false, ""),
   new DateTime(2000, 01, 01));

For Web

To pass parameters to a function in the class ICSSoft.STORMNET.Web.Tools.AdvLimitUtils there is a method:

/// <summary> 
/// Substitute a specific value instead of function parameters. 
/// </summary> 
/// <param name="function">the function that will replace the parameters.</param> 
/// <param name="paramValues">the Reference values of parameters (parameter name - value).</param> 
/// <returns>the Function in which all parameters replaced by the appropriate values.</returns> 
public static Function SubstituteParameters(Function function, IDictionary<string, object> paramValues)


    limitFunction = AdvLimitUtils.SubstituteParameters(
    new Dictionary<string, object>() { {Date, DateTime.Now} });

For Win

For parameter substitution in the bounding function in the class ICSSoft.STORMNET.Windows.Forms.AdvansedLimitExtension there is a method:

/// <summary> 
 /// Get restriction with the substituted parameter values 
 /// </summary> 
 /// <param name="advansedLimit">the constraint.</param> 
 /// <param name="parValues">a Dictionary with parameter values. Key - the parameter name</param> 
 /// <returns>the Function-restriction with the substituted values of the parameters</returns> 
 public static Function GetCustomizedFunctionByParameters<R, T>(this R advansedLimit, T parValues)
     where T : IDictionary, IDictionary<string, object>
     where R : AdvansedLimit

But for this method you need an instance of the class ICSSoft.STORMNET.Windows.Forms.AdvansedLimit (object model limitations includes both the bounding function and parameter setting).


 AdvansedLimit advlimit = new AdvansedLimit {Function = limitFunction};
 advlimit.Parameters = new ParameterDef[1] { (ParameterDef)advlimit.Function.Parameters[0] };
 limitFunction = AdvansedLimitExtension.GetCustomizedFunctionByParameters(
    new Dictionary<string, object>() { { Date, DateTime.Now } });
