View One Procedure

by Les Smith

Simulating the "View One Procedure" feature of the VB6 IDE.  Remember the feature in VB6 where you could view one procedure at a time rather than all procedures with a line separating them?  When you have very large procedures, this is still a useful feature.  The following code will produce the same effect when executed as a macro or in an add-in.  The code is currently set up to be run as a macro.  You can put it in an add-in by simply changing the references to "DTE" to the applicationObject variable in the add-in.

Public Sub HideAllButCurrentMethod()       ' Collapses all code preceding and following       ' procedure where cursor resides.  This emulates       ' the VB6 One Function View Feature.       Try          Dim ts As TextSelection = DTE.ActiveWindow.Selection          ' where caret was          Dim tsSave As EditPoint = ts.ActivePoint.CreateEditPoint          ' where caret is currently as we move          Dim ep As EditPoint = ts.ActivePoint.CreateEditPoint          Dim i As Integer          Dim j As Integer          Dim k As Integer          DTE.ExecuteCommand("Edit.StopOutlining")          '' determine #chars from start of doc to line          '' before start of current proc          '' move to stare of current proc          ep.MoveToPoint(ep.CodeElement(EnvDTE.vsCMElement.             vsCMElementFunction).GetStartPoint(vsCMPart.vsCMPartWhole))          ep.LineUp()          i = ep.AbsoluteCharOffset ' number of lines to hide at top          Dim doc As TextDocument = oVB.ActiveDocument.Object          Dim epStart As EditPoint = doc.StartPoint.CreateEditPoint          epStart.OutlineSection(i)          '' Move ep back in function and outline from end          '' of proc to end of doc.          ' move back to editpoint          ts.MoveToPoint(tsSave, False)          ep = ts.ActivePoint.CreateEditPoint          ep.MoveToPoint(ep.CodeElement(EnvDTE.vsCMElement.            vsCMElementFunction).GetEndPoint(vsCMPart.vsCMPartWhole))          ep.LineDown()          j = ep.AbsoluteCharOffset ' #chars to end of proc          Dim epEOD As EditPoint = doc.EndPoint.CreateEditPoint          k = epEOD.AbsoluteCharOffset          ep.OutlineSection(k - j)          ts.MoveToPoint(tsSave)       Catch ex As System.Exception       End Try    End Sub

If you want to return to viewing all methods, calling the following macro will accomplish that for you.  Again, to use the code in an add-in, simply replace all references to "DTE" with the applicationObject variable.

Public Sub RedoOutlining()       Try          DTE.ExecuteCommand("Edit.StopOutlining")          DTE.ExecuteCommand("Edit.StartAutomaticOutlining")          DTE.ExecuteCommand("Edit.ToggleAllOutlining")       Catch ex As System.Exception       End Try    End Sub
