SerializePassword Property (AnnObject)

Summary

Gets or sets a value indicating whether the password is saved when this AnnObject is serialized.

Syntax

C++

public virtual bool SerializePassword {get; set;}

  
Public Overridable Property SerializePassword As Boolean

public: 
virtual property bool SerializePassword { 
   bool get(); 
   void set (    bool ); 
}

Property Value

true if this password is saved when this AnnObject is serialized; false otherwise.

Remarks

Serialization is used throughout the annotation toolkit to save object states. For example, the annotation mode uses serialization to implement undo/redo buffers, copying/pasting objects to/from the clipboard as well as loading/saving objects to files or memory. Setting this property to false will not store the password field of a locked object when the object is serialized. This is not necessary in some situations such as implementing undo/redo buffers, but is very important to applications that do not want to save the password when objects are saved to disk files.

Example

This example will implement copying/pasting all objects from a container to the clipboard.

using Leadtools.Annotations;

using Leadtools.WinForms; 
using Leadtools.Drawing; 
 
///  
private static readonly string clipboardFormatName = "LeadtoolsAnnotations"; 
public void AnnObject_SerializePassword(AnnContainer container) 
{ 
   // first create a temporary object collection and copy all objects in the container into it 
   RasterCollection<AnnObject> destObjects = new RasterCollection<AnnObject>(); 
   foreach (AnnObject srcObj in container.Objects) 
   { 
      AnnObject destObj = srcObj.Clone() as AnnObject; 
      // we do not want to save the password of locked objects to the clipbaord 
      destObj.SerializePassword = false; 
      destObjects.Add(destObj); 
   } 
 
   // copy this object collection to the clipboard 
   DataFormats.Format format = DataFormats.GetFormat(clipboardFormatName); 
   DataObject dataObj = new DataObject(clipboardFormatName, destObjects); 
   Clipboard.SetDataObject(dataObj); 
} 
 
private void PasteObjectsFromClipboard(AnnContainer container) 
{ 
   // check if the clipboard has LEADTOOLS annotations objects 
   IDataObject data = Clipboard.GetDataObject(); 
   if (data != null) 
   { 
      DataFormats.Format format = DataFormats.GetFormat(clipboardFormatName); 
      if (data.GetDataPresent(clipboardFormatName)) 
      { 
         // get the object collection from the clipboard 
         RasterCollection<AnnObject> objects = data.GetData(clipboardFormatName) as RasterCollection<AnnObject>; 
 
         // move the objects from this collection to the container 
         while (objects.Count > 0) 
         { 
            AnnObject obj = objects[0]; 
            objects.RemoveAt(0); 
            container.Objects.Add(obj); 
         } 
      }
