Displays a prompt for entering customized parameters. This is called when the Calculate method is called and there is insufficient data to fit a model.

Syntax

  • GetDistrParameters( sender As WeibullDataSet, sMsg As String , GetOnlyOneParameter As Boolean , Params As List( Of ParamInputInfo ) , Cancel As Boolean)

Parameters

sender: A WeibullDataSet object.
sMsg: The main display label.
GetOnlyOneParameter: The prompt for only one parameter.
Params: A list of ParamInputInfo objects that would be updated by this prompt. After processing with this event handler, the Value of each ParamInputInfo object will be updated.
Cancel: If the prompt was closed by any means other than clicking "Okay," this value will be set to True.

Usage Example

Declare a New class that Inherits from WeibullEvents.
Override the method.

       Private Class myEvents
           Inherits WeibullEvents
           Public Overrides Sub GetDistrParameters(sender As WeibullDataSet, sMsg As String, GetOnlyOneParamater As Boolean, Params As List(Of ParamInputInfo), ByRef Cancel As Boolean)
               MyBase.GetDistrParameters(sender, sMsg, GetOnlyOneParamater, Params, Cancel)
               MessageBox.Show("Additional overridden code here.")
           End Sub
       End Class

Declare the WeibullDataSet.

       Dim WDS as New WeibullDataSet

Use the created myEvents class in place of the one created by the dataset.

       WDS.Events = New myEvents

Creates a new list of ParamInputInfo. Populate the list.

       Dim Params As New List(Of ParamInputInfo)
       Params.Add(New ParamInputInfo("Param1", 0, 10, False, True))
       Params.Add(New ParamInputInfo("Param2", 0, Double.MaxValue, False, True))

Create a Boolean for return of "Cancel" parameter.

       Dim wasCanceled As Boolean

Prompt user to input the parameters.

       WDS.Events.GetDistrParameters(WDS, "Message1", True, Params, wasCanceled)

The new Parameter values are in their respective ParamInputInfo.Value variables.

       Dim NewParameter1value As Double
       Dim NewParameter2value As Double 
       If Not wasCanceled Then
            NewParameter1value = Params(0).Value
            NewParameter2value = Params(1).Value
       End If
