Allows you to manipulate text as data in text buffers.
Assembly: EnvDTE (in EnvDTE.dll)
objects are similar to TextSelection objects, except that they operate on data in the text buffer rather than on text displayed in a code editor. The difference is that text in the buffer is not affected by global editor states, such as word wrapping and virtual spaces.
Any operation that attempts to modify a text document fails if it affects any characters that are contained in a read-only block, or if the document itself is read-only.
