The ViewFile() method opens the specified file in the appropriate viewer application using the Windows Open verb.

Syntax

'Declaration
 
Public Shared Sub ViewFile( _
   ByVal path As String, _
   ByVal docType As String _
) 
public static void ViewFile( 
   string path,
   string docType
)

Parameters

path
Required. Holds the path and file name of the file, including the file extension.
docType

Required. Holds the file extension of the file, including the leading period (.) of the extension. This parameter is used to look up the view arguments in the File_Type table to pass to Windows with the Open verb.

Exceptions

ExceptionDescription
System.Exception Thrown if an error occurs retrieving information from the database.
System.ComponentModel.Win32Exception Thrown if there is an error starting the program for viewing.

Remarks

When the method is called, it looks up the file extension supplied by the docType parameter in the File_Type table to get the view arguments in the view_args column. If the view arguments contain a %FA parameter, it is removed from the arguments. The file name and view arguments are then passed to Windows using the Open verb to open the file in the appropriate application.
