GetPasswordCallback Property

Summary

Gets or sets the password callback to use when openning encrypted documents.

Syntax

C++

public Leadtools.Forms.Documentreaders.DocumentReaderGetPasswordCallback GetPasswordCallback {get; set;}

Public Property GetPasswordCallback As Leadtools.Forms.Documentreaders.DocumentReaderGetPasswordCallback

public: 
property Leadtools.Forms.Documentreaders.DocumentReaderGetPasswordCallback^ GetPasswordCallback { 
   Leadtools.Forms.Documentreaders.DocumentReaderGetPasswordCallback^ get(); 
   void set (    Leadtools.Forms.Documentreaders.DocumentReaderGetPasswordCallback^ ); 
}

Property Value

A DocumentReaderGetPasswordCallback object that specifies the password callback to use when opening encrypted documents. The default value is null.

Remarks

Some of the documents opened by the reader such as PDF might be encrypted with a password. To open these documents, you must use one of the following:

If the password is known in advance, then simply set it in the Password property of the DocumentReaderLoadOptions instance passed to DocumentReader.Create.
If the password is unknown before loading, then set a callback in the GetPasswordCallback property. The reader will invoke this callback when an encrypted document is encountered. You can then prompt the user for the password using a dialog box.

Example

For an example, refer to DocumentReaderLoadOptions.
