IDataObject.SetData Method

public:
 void SetData(System::Object ^ data);

public void SetData (object data);

public void SetData (object? data);

abstract member SetData : obj -> unit

Public Sub SetData (data As Object)

Parameters

Examples

This example uses the DataObject class, which implements IDataObject, to demonstrate the use of the SetData method. First, it creates a component (myComponent) and stores it in a data object (myDataObject). Then it checks whether the specified data is stored in the data object, and displays the result in a message box. The example assumes that you have created a Form named Form1.

private:
   void SetData1()
   {
      // Creates a component to store in the data object.
      Component^ myComponent = gcnew Component;
      
      // Creates a data object.
      DataObject^ myDataObject = gcnew DataObject;
      
      // Adds the component to the data object.
      myDataObject->SetData( myComponent );
      
      // Checks whether data of the specified type is in the data object.
      Type^ myType = myComponent->GetType();
      String^ myMessageText;
      if ( myDataObject->GetDataPresent( myType ) )
      {
         myMessageText = "Data of type " + myType->Name +
            " is present in the data object";
      }
      else
      {
         myMessageText = "Data of type " + myType->Name +
            " is not present in the data object";
      }
      
      // Displays the result in a message box.
      MessageBox::Show( myMessageText, "The Test Result" );
   }

private void SetData1() 
{
    // Creates a component to store in the data object.
    Component myComponent = new Component();
 
    // Creates a data object.
    DataObject myDataObject = new DataObject();

    // Adds the component to the data object.
    myDataObject.SetData(myComponent);
 
    // Checks whether data of the specified type is in the data object.
    Type myType = myComponent.GetType();
    string myMessageText;
    if(myDataObject.GetDataPresent(myType))
         myMessageText = "Data of type " + myType.Name + 
            " is present in the data object";
    else
        myMessageText = "Data of type " + myType.Name +
            " is not present in the data object";

    // Displays the result in a message box.
    MessageBox.Show(myMessageText, "The Test Result"); 
}

Private Sub SetData1()
   ' Creates a component to store in the data object.
   Dim myComponent As New System.ComponentModel.Component()
   
   ' Creates a data object.
   Dim myDataObject As New DataObject()
   
   ' Adds the component to the data object.
   myDataObject.SetData(myComponent)
   
   ' Checks whether data of the specified type is in the data object.
   Dim myType As Type = myComponent.GetType()
   Dim myMessageText As String
   If myDataObject.GetDataPresent(myType) Then
      myMessageText = "Data of type " + myType.Name + " is present in the data object"
   Else
      myMessageText = "Data of type " + myType.Name + " is not present in the data object"
   End If

   ' Displays the result in a message box.
   MessageBox.Show(myMessageText, "The Test Result")
End Sub

Remarks

The format is derived from the data class.

Data stored using this method can be converted to a compatible format when it is retrieved.

For an implementation of this method, see DataObject.SetData.

Parameters

Examples

This example uses the DataObject class, which implements IDataObject, to demonstrate the use of the SetData method. First, it creates a data object (myDataObject) and stores a string in the object specifying the UnicodeText format. Then it retrieves that data stored in the object specifying the Text format, so that the data is converted to the Text format. The result is displayed in a message box. This example assumes that you have created a Form named Form1.

private:
   void SetData2()
   {
      // Creates a data object.
      DataObject^ myDataObject = gcnew DataObject;
      
      // Stores a string, specifying the UnicodeText format.
      myDataObject->SetData( DataFormats::UnicodeText, "Hello World!" );
      
      // Retrieves the data by specifying the Text format.
      String^ myMessageText = "The data type is " +
         myDataObject->GetData( DataFormats::Text )->GetType()->Name;
      
      // Displays the result.
      MessageBox::Show( myMessageText, "The Test Result" );
   }

private void SetData2() 
{
    // Creates a data object.
    DataObject myDataObject = new DataObject();
 
    // Stores a string, specifying the UnicodeText format.
    myDataObject.SetData(DataFormats.UnicodeText, "Hello World!");
 
    // Retrieves the data by specifying the Text format.
    string myMessageText = "The data type is " + myDataObject.GetData(DataFormats.Text).GetType().Name;

    // Displays the result.
    MessageBox.Show(myMessageText, "The Test Result");
}

Private Sub SetData2()
   ' Creates a data object.
   Dim myDataObject As New DataObject()
   
   ' Stores a string, specifying the UnicodeText format.
   myDataObject.SetData(DataFormats.UnicodeText, "Hello World!")
   
   ' Retrieves the data by specifying the Text format.
   Dim myMessageText As String = "The data type is " & _
             myDataObject.GetData(DataFormats.Text).GetType().Name
   
   ' Displays the result.
   MessageBox.Show(myMessageText, "The Test Result")
End Sub

Remarks

If you do not know the format of the target application, you can store data in multiple formats using this method.

Data stored using this method can be converted to a compatible format when it is retrieved.

For an implementation of this method, see DataObject.SetData.

Parameters

Examples

This example uses the DataObject class, which implements IDataObject, to demonstrate the use of the SetData method. First, it creates a component (myComponent) and stores it in a data object (myDataObject), using myType to specify the data format. Then it checks whether the data of the specified type is stored in the object, and displays the result in a message box. The example assumes that you have created a Form named Form1.

Parameters

Examples

This example uses the DataObject class, which implements IDataObject, to demonstrate the use of the SetData method. First, it creates a data object (myDataObject) and stores a UnicodeText string in it, with the autoConvert parameter set to false. Then it retrieves the format(s) associated with the data stored in the object and displays the result in a message box. The only format associated with the data is the UnicodeText format. This example assumes that you have created a Form named Form1.

private:
   void SetData4()
   {
      // Creates a new data object.
      DataObject^ myDataObject = gcnew DataObject;

      // Adds UnicodeText string to the object, and set the autoConvert
      // parameter to false.
      myDataObject->SetData( DataFormats::UnicodeText, false, "My text String*" );

      // Gets the data format(s) in the data object.
      array<String^>^arrayOfFormats = myDataObject->GetFormats();

      // Stores the results in a string.
      String^ theResult = "The format(s) associated with the data are: \n";
      for ( int i = 0; i < arrayOfFormats->Length; i++ )
         theResult = theResult + arrayOfFormats[ i ], " \n";

      // Show the results in a message box.
      MessageBox::Show( theResult );
   }

       private void SetData4() 
       {
           // Creates a new data object.
           DataObject myDataObject = new DataObject();

           // Adds UnicodeText string to the object, and set the autoConvert 
           // parameter to false.
           myDataObject.SetData(DataFormats.UnicodeText, false, "My text string");

           // Gets the data format(s) in the data object.
           String[] arrayOfFormats = myDataObject.GetFormats();

           // Stores the results in a string.
           string theResult = "The format(s) associated with the data are:" + '\n';
           for(int i=0; i<arrayOfFormats.Length; i++)
               theResult += arrayOfFormats[i] + '\n';
           
           // Show the results in a message box. 
           MessageBox.Show(theResult);
       }

Private Sub SetData4()
    ' Creates a new data object.
    Dim myDataObject As New DataObject()

    ' Adds UnicodeText string to the object, and set the autoConvert
    ' parameter to false.
    myDataObject.SetData(DataFormats.UnicodeText, False, "My text string")

    ' Gets the data format(s) in the data object.
    Dim arrayOfFormats As [String]() = myDataObject.GetFormats()

    ' Stores the results in a string.
    Dim theResult As String = "The format(s) associated with the data are:" + _
            ControlChars.Cr
    Dim i As Integer
    For i = 0 To arrayOfFormats.Length - 1
        theResult += arrayOfFormats(i) + ControlChars.Cr
    Next i
    ' Show the results in a message box. 
    MessageBox.Show(theResult)
End Sub
