Remarks
Starting in Visual Studio 2010, you should access the text buffer on the UI thread, not on background threads. The text buffer no longer gets locked when you call LockBuffer or LockBufferEx. Similarly, the UnlockBuffer and UnlockBufferEx methods no longer have any effect.
COM Signature
From textmgr.idl:
HRESULT IVsTextLines::LockBufferEx(
[in] DWORD dwFlags
);
When the LockBufferEx method is called by one thread, no other thread can perform write operations on the buffer. To unlock the buffer, call UnlockBufferEx.
