ExceptionMessageBox.CheckBoxRegistryKey Property
Sets an opened RegistryKey that controls the check box that is displayed on the exception message box when Microsoft.SqlServer.MessageBox.ExceptionMessageBox.ShowCheckbox is true.
Namespace: Microsoft.SqlServer.MessageBox
Assembly: Microsoft.ExceptionMessageBox (in Microsoft.ExceptionMessageBox.dll)
Property Value
Type: Microsoft.Win32.RegistryKeyA RegistryKey that controls the check box that is displayed on the exception message box when Microsoft.SqlServer.MessageBox.ExceptionMessageBox.ShowCheckbox is true.
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.
