Examples

The following code example demonstrates the use of this member.

FileStream^ myFileStream = File::Open( "Temp.dif", FileMode::Open );

// Store the data into Dif format.
DataObject^ myDataObject = gcnew DataObject;
myDataObject->SetData( DataFormats::Dif, myFileStream );

// Check whether the data is stored or not in the specified format.
bool formatPresent = myDataObject->GetDataPresent( DataFormats::Dif );
if ( formatPresent )
{
   Console::WriteLine( "The data has been stored in the Dif format is:'{0}'", formatPresent );
}
else
{
   Console::WriteLine( "The data has not been stored in the specified format" );
}

 FileStream myFileStream = File.Open("Temp.dif",FileMode.Open);
 // Store the data into Dif format.
 DataObject myDataObject = new DataObject();
 myDataObject.SetData(DataFormats.Dif,myFileStream);

// Check whether the data is stored or not in the specified format.
bool formatPresent = myDataObject.GetDataPresent(DataFormats.Dif);
 if(formatPresent) 
 {
    Console.WriteLine("The data has been stored in the Dif format is:'"+formatPresent+"'");
 } 
 else 
 {
    Console.WriteLine("The data has not been stored in the specified format");
 }

Dim myFileStream As FileStream = File.Open("Temp.dif", FileMode.Open)
' Store the data into Dif format.
Dim myDataObject As New DataObject()
myDataObject.SetData(DataFormats.Dif, myFileStream)

' Check whether the data is stored or not in the specified format.
Dim formatPresent As Boolean = myDataObject.GetDataPresent(DataFormats.Dif)
If formatPresent Then
   Console.WriteLine(("The data has been stored in the Dif format is:'" + formatPresent.ToString() + "'"))
Else
   Console.WriteLine("The data has not been stored in the specified format")
End If

Remarks

DIF is a format consisting of ASCII codes in which database, spreadsheet, and similar documents can be structured to facilitate their use by and transfer to other programs.

This field is used by the IDataObject interface and the DataObject class to specify the data type.

When adding to an IDataObject or to an implementation of DataObject, use this field as the format for the IDataObject.SetData and DataObject.SetData methods.

To see if an object of this type exists, use this field as the format for the IDataObject.GetDataPresent and DataObject.GetDataPresent methods.

To get an object of this type, use this as the format for the IDataObject.GetData and DataObject.GetData methods.
