Collapsing all items in the Solution Explorer in Visual Studio

I sometimes get fed up up having to go through clicking solution folders to collapse everything to went on the hunt for a macro and came across this script by Scott Kuhl.

Sub CollapseAll()

' Get the the Solution Explorer tree
Dim solutionExplorer As UIHierarchy
solutionExplorer = DTE.Windows.Item(Constants.vsext_wk_SProjectWindow).Object()

' Check if there is any open solution
If (solutionExplorer.UIHierarchyItems.Count = 0) Then
Return
End If

' Get the top node (the name of the solution)
Dim rootNode As UIHierarchyItem = solutionExplorer.UIHierarchyItems.Item(1)
rootNode.DTE.SuppressUI = True

' Collapse each project node
Collapse(rootNode, solutionExplorer)

' Select the solution node, or else when you click
' on the solution window
' scrollbar, it will synchronize the open document
' with the tree and pop
' out the corresponding node which is probably not what you want.

rootNode.Select(vsUISelectionType.vsUISelectionTypeSelect)
rootNode.DTE.SuppressUI = False

End Sub

Private Sub Collapse(ByVal item As UIHierarchyItem, ByRef solutionExplorer As UIHierarchy)

For Each innerItem As UIHierarchyItem In item.UIHierarchyItems
If innerItem.UIHierarchyItems.Count > 0 Then

' Re-cursive call
Collapse(innerItem, solutionExplorer)

' Collapse
If innerItem.UIHierarchyItems.Expanded Then
innerItem.UIHierarchyItems.Expanded = False
If innerItem.UIHierarchyItems.Expanded = True Then
' Bug in VS 2005
innerItem.Select(vsUISelectionType.vsUISelectionTypeSelect)
solutionExplorer.DoDefaultAction()
End If
End If

End If
Next

End Sub

Simply add a new Macro to visual Studio then paste in the code.

It can be run directly from the MyMacros window or if it is something you use a lot assign a shortcut key to it by doing the follwing:

Tools|Customize|Commands|Press the Keyboard Button|type the namespace path to the new macro and assign the key sequence. Voila.

Here is the link to the blog i got the script from.
