TargetFile Property (ConvertCtrl)

Show in webframe
Example 



Gets or sets the media target filename.
Syntax
'Declaration
 
Public Overridable Property TargetFile As String
'Usage
 
Dim instance As ConvertCtrl
Dim value As String
 
instance.TargetFile = value
 
value = instance.TargetFile
public virtual string TargetFile {get; set;}
public:
virtual property String^ TargetFile {
   String^ get();
   void set (    String^ value);
}

Property Value

A string value representing the target filename.
Remarks
This property allows the user to set the output of the conversion process to the specified filename. If the TargetFormat property is TargetFormatType.DVD, then the TargetFile property contains the directory in which the DVD image is located. Otherwise, the TargetFile property contains the name of a media file. If the TargetFile property refers to a directory, it should contain the full path to the directory. A relative path can be used, but it is not recommended because relative paths are somewhat unpredictable. If the target format type is TargetFormatType.DVD and the TargetFile property contains the name of an existing file, that file will be deleted, and a directory or folder will be created with the same name. The filename can be used to indicate a regular file or a stream. For more details on the filename syntax, refer to: TargetFile Syntax.

Assignment can raise an error exception. For more information, refer to the Error Codes.
