Reset Method

Summary

Removes the contents of the Directory and reinitializes it.

Syntax
C#
VB
C++
public void Reset( 
   string destinationFolder 
) 
Public Sub Reset( _ 
   ByVal destinationFolder As String _ 
)  
public: 
void Reset(  
   String^ destinationFolder 
)  

Parameters

destinationFolder
The name of an existing destination folder in which to save the DICOMDIR File.

Remarks

When an object of the DicomDir class is created, the DICOM Directory, as specified by the object, is empty. To revert to this case at any time, call the method Reset. If the same object is to be used to create the DICOM Directory of a new file-set, this method must be called first. This method also sets the destination folder of the DICOMDIR File. Please note that although the method can be passed a null reference (Nothing in VB), no DICOM file can be added to the DICOM Directory unless this folder is specified.

Example
C#
VB
using Leadtools; 
using Leadtools.Dicom; 
 
public class MyDicomDir : DicomDir 
{ 
   public MyDicomDir(string destinationFolder, string path) : base(destinationFolder, path) { } 
   public override DicomDirInsertFileCommand OnInsertFile(string fileName, DicomDataSet ds, DicomDirInsertFileStatus status, DicomExceptionCode code) 
   { 
      if (status == DicomDirInsertFileStatus.PreAdd) 
      { 
         string msg = string.Format("About to add the file '{0}'{1}{1}Proceed?", fileName, Environment.NewLine); 
         DialogResult result = MessageBox.Show(msg, "Sample", MessageBoxButtons.YesNoCancel); 
         if (result == DialogResult.Yes)
