Remarks
IDesignerOptionService provides an interface that can be used to retrieve and update the values of the Windows Forms Designer options, which are listed within the dialog displayed by the Options command of the Tools menu of the Visual Studio .NET development environment. The GetOptionValue method retrieves the value of a specified option. The SetOptionValue method sets a specified value for a specified option.
Example
[Visual Basic, C#, C++] The following code example demonstrates accessing the IDesignerOptionService to display the current values of the standard options.
