ResumeCalc メソッド

SuspendCalc の先行呼び出しの後に自動計算を再開します。

シンタックス

Visual Basic

'宣言
 
Public Sub ResumeCalc() 

C#

public void ResumeCalc()

解説

ResumCalc メソッドは SuspendCalc メソッドへの先行呼び出しが行われた後で、自動計算を再開します。

SuspendCalcが呼び出されるたびにカウンタが増える点にも注意してください。計算を再開する前に ResumeCalc を同じ回数呼び出す必要があります。ResumeCalc への呼び出しの結果がカウンターで 0 に達した場合、計算がすぐに実行されます。UltraCalcManager はタイマー チックまたは変更通知を待ちません。

使用例

Visual Basic

Imports Infragistics.CalcEngine
Imports Infragistics.Win.UltraWinCalcManager

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

        'Suspend calculation while we are adding new items into the calc network
        Me.UltraCalcManager1.SuspendCalc()

        Dim calcSettings As CalcSettings

        'Set CalcSettings properties on TextBox1
        calcSettings = Me.UltraCalcManager1.GetCalcSettings(Me.textBox1)
        calcSettings.PropertyName = "Text"
        calcSettings.Alias = "Height"
        calcSettings.ErrorValue = 1

        'Set CalcSettings properties on TextBox2
        calcSettings = Me.UltraCalcManager1.GetCalcSettings(Me.textBox2)
        calcSettings.PropertyName = "Text"
        calcSettings.Alias = "Width"
        calcSettings.ErrorValue = 1

        'Create a NamedReference to calulate the area. 
        Dim namedReference As NamedReference
        namedReference = Me.UltraCalcManager1.NamedReferences.Add("Area", "[//Height] * [//Width]")
        namedReference.ErrorValue = "Error"

        'Everything is added, so resume
        Me.UltraCalcManager1.ResumeCalc()

    End Sub

    Private Sub UltraCalcManager1_CalculationsCompleted(ByVal sender As Object, ByVal e As System.EventArgs) Handles UltraCalcManager1.CalculationsCompleted
        If (Me.UltraCalcManager1.NamedReferences.Exists("Area")) Then
            Me.textBox3.Text = Me.UltraCalcManager1.NamedReferences("Area").FormulaResult.Value.ToString()
        End If
    End Sub
