IncrementalSearch.DeleteCharAndBackup Method

Removes one character from the search pattern and moves the selection back to the previous match.

Namespace:  EnvDTE80
Assembly:  EnvDTE80 (in EnvDTE80.dll)

Syntax

'Declaration
Function DeleteCharAndBackup As vsIncrementalSearchResult
vsIncrementalSearchResult DeleteCharAndBackup()
vsIncrementalSearchResult DeleteCharAndBackup()
abstract DeleteCharAndBackup : unit -> vsIncrementalSearchResult
function DeleteCharAndBackup() : vsIncrementalSearchResult

Return Value

Type: EnvDTE80.vsIncrementalSearchResult
A vsIncrementalSearchResult enumeration.

Remarks

DeleteCharAndBackup effectively reverses the last search action. The last character in the pattern is removed and the selection is moved to the previous match (regardless of the direction of the search.)

Examples

Sub testIS2()
    ' Before running, open a document in Visual Studio.
    ' Set variables for text pane.
    Dim tp As EnvDTE80.TextPane2
    tp = CType(DTE.ActiveDocument.ActiveWindow.Object.ActivePane, _
    TextPane2)
    ' Start an incremental search backward from
    ' the current insertion point in the document.
    tp.IncrementalSearch.StartBackward()
    ' Add the character "a" to the search pattern.
    tp.IncrementalSearch.AppendCharAndSearch(Asc("a"))
    ' Display the parent name for IncrementalSearch object.
    MsgBox("IncrementalSearch parent: " & _
    tp.IncrementalSearch.DTE.FullName)
    MsgBox("Search pattern length: " & _
    tp.IncrementalSearch.Pattern.Length)
    ' Perform incremental search using the pattern ("a").
    tp.IncrementalSearch.SearchWithLastPattern()
    ' After the search, exit incremental search mode.
    MsgBox("DeleteCharAndBackup")
    tp.IncrementalSearch.DeleteCharAndBackup()
    MsgBox("SearchForward")
    tp.IncrementalSearch.SearchForward()
    MsgBox("SearchBackward")
    tp.IncrementalSearch.SearchBackward()
    MsgBox("Exit")
    tp.IncrementalSearch.Exit()
End Sub
