属性值

类型：Microsoft.Win32.RegistryKey
A RegistryKey that controls the check box that is displayed on the exception message box when ShowCheckbox is true.

注释

This property is used with CheckBoxRegistryValue to initialize the selected state of the check box. If the specified registry value exists and contains a non-zero value, the check box is displayed as selected; otherwise, the check box is displayed as clear. If CheckBoxRegistryMeansDoNotShowDialog is true and the registry value exists and contains a non-zero value, the message box is not displayed and ExceptionMessageBox returns DefaultDialogResult when Show is called.

The RegistryKey must be opened by the application prior to calling Show.

示例

          try
            {
                // Do something that could generate an exception.
                throw new ApplicationException("An error has occured.");
            }
            catch (ApplicationException ex)
            {
                string str = "The action failed. Do you want to continue?";
                ApplicationException exTop = new ApplicationException(str, ex);
                exTop.Source = this.Text;

                    ExceptionMessageBoxDefaultButton.Button2);
