IConnectedCells.LocateByDiagonalOfEnvelope Method

[Visual Basic .NET]
Public Sub LocateByDiagonalOfEnvelope ( _
    ByVal Value As Double, _
    ByVal lessThan As Boolean, _
    ByVal equalTo As Boolean, _
    ByVal Foreground As Boolean, _
    ByVal bounds As IGeometry, _
    ByVal callbackSel As INotifySelectionBlock, _
    ByVal trackCancel As ITrackCancel, _
    ByVal stepProgressor As IStepProgressor _
)

[C#]
public void LocateByDiagonalOfEnvelope (
    double Value,
    bool lessThan,
    bool equalTo,
    bool Foreground,
    IGeometry bounds,
    INotifySelectionBlock callbackSel,
    ITrackCancel trackCancel,
    IStepProgressor stepProgressor
);

Available with ArcGIS Desktop. Requires ArcScan Extension.

[C#]

The following code shows an example of this method in C#.

//You can get app from ICommand :: OnCreate() hook parameter

public void LocateByDiag()
{
  IConnectedCells connectedCells=m_app.FindExtensionByName("ESRI ArcScan Tools") as IConnectedCells;
  IMxDocument mxDoc=m_app.Document as IMxDocument;
  INotifySelectionBlock foundBlock=new FoundBlock();
  connectedCells.LocateByDiagonalOfEnvelope(1000, true, true, true, mxDoc.ActiveView.Extent, foundBlock, null, null);
}

Also create a new class (FoundBlock) with the following code.

public class FoundBlock : ESRI.ArcGIS.ArcScan.INotifySelectionBlock 
{
  public FoundBlock()
  { 
  }
  #region INotifySelectionBlock Members
  void ESRI.ArcGIS.ArcScan.INotifySelectionBlock.SelectionBlock(ref ESRI.ArcGIS.Display.tagRECT rectangle, object block, ESRI.ArcGIS.esriSystem.ITrackCancel cancel)
  {
    System.Diagnostics.Debug.Print("Found block");
  }
  #endregion
}
