Parameters

• textView
  Type: Microsoft.VisualStudio.TextManager.Interop.IVsTextView

  An IVsTextView object representing the view containing the source where the command was entered.

• command
  Type: Microsoft.VisualStudio.VSConstants.VSStd2KCmdID

  A value from the VSConstants.VSStd2KCmdID enumeration specifying the command that was entered.

• ch
  Type: Char

  The character that was typed.

Remarks

This method is called when a command is entered. All this method does is support IntelliSense operations.

By the time this method is called, any character the user has just typed has been added to the source file just before the current caret position.

The base method does nothing if the EnableCodeSense property is false. Otherwise, this method gets the current caret position and then the token at the current caret position. Based on the token triggers and what the command is, the appropriate method that supports the desired IntelliSense operation is called.

Trigger	Command	Method Called
MemberSelect	TYPECHAR	Completion
MatchBraces	TYPECHAR	MatchBraces
MethodTip	TYPECHAR	MethodTip
ParameterNext	parameter separator	AdjustCurrentParameter
