範例

下列範例說明如何建立新的 ColorDialog 。 這個範例會要求從現有表單內呼叫 方法,且該表單上已 TextBoxButton 放置 和 。

private:
   void button1_Click( Object^ /*sender*/, System::EventArgs^ /*e*/ )
   {
      ColorDialog^ MyDialog = gcnew ColorDialog;
      // Keeps the user from selecting a custom color.
      MyDialog->AllowFullOpen = false;
      // Allows the user to get help. (The default is false.)
      MyDialog->ShowHelp = true;
      // Sets the initial color select to the current text color.
      MyDialog->Color = textBox1->ForeColor;
      
      // Update the text box color if the user clicks OK 
      if ( MyDialog->ShowDialog() == ::System::Windows::Forms::DialogResult::OK )
      {
         textBox1->ForeColor = MyDialog->Color;
      }
   }
private void button1_Click(object sender, System.EventArgs e)
 {
    ColorDialog MyDialog = new ColorDialog();
    // Keeps the user from selecting a custom color.
    MyDialog.AllowFullOpen = false ;
    // Allows the user to get help. (The default is false.)
    MyDialog.ShowHelp = true ;
    // Sets the initial color select to the current text color.
    MyDialog.Color = textBox1.ForeColor ;
    
    // Update the text box color if the user clicks OK 
    if (MyDialog.ShowDialog() == DialogResult.OK)
        textBox1.ForeColor =  MyDialog.Color;
 }
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    Dim MyDialog As New ColorDialog()
    ' Keeps the user from selecting a custom color.
    MyDialog.AllowFullOpen = False
    ' Allows the user to get help. (The default is false.)
    MyDialog.ShowHelp = True
    ' Sets the initial color select to the current text color,
    MyDialog.Color = TextBox1.ForeColor

    ' Update the text box color if the user clicks OK 
    If (MyDialog.ShowDialog() = Windows.Forms.DialogResult.OK) Then
        TextBox1.ForeColor = MyDialog.Color
    End If
End Sub

備註

當設定為 false 時,對話方塊中的關聯按鈕會停用,而且使用者無法存取對話方塊中的自訂色彩控制項。
