Q248078: BUG: VSSVersion Collection Does Not Give Filenames |
/kb/248/Q248078/ |

Article: Q248078
Product(s): Microsoft SourceSafe
Version(s): WINDOWS:5.0,6.0
Operating System(s):
Keyword(s): kbAutomation kbSSafe500bug kbSSafe600bug _IK kbGrpDSSSafe
Last Modified: 01-MAY-2001
-------------------------------------------------------------------------------
The information in this article applies to:
- Microsoft Visual SourceSafe for Windows, versions 5.0, 6.0
-------------------------------------------------------------------------------
SYMPTOMS
========
When looping through the VSSVersions collection, the name of the file that the
action is about is not readily available.
RESOLUTION
==========
One workaround for the "Add" action is to compare the items in the project of
the version in question with the previous version. Whatever file is in the
current version and not in the previous version is the file that was added.
STATUS
======
Microsoft has confirmed this to be a bug in the Microsoft products listed at the
beginning of this article.
MORE INFORMATION
================
Steps to Reproduce Behavior
---------------------------
NOTE: This procedure uses Microsoft Visual Basic, but the same could be done in
other languages.
1. Create a standard EXE project in Visual Basic.
2. Create a reference to the Microsoft SourceSafe 6.0 (or 5.0) library
(Ssapi.dll).
3. Add a command button to Form1.
4. Double-click the button.
5. Paste the following code in the Command1_Click Sub:
Dim SSDB As New VSSDatabase
Dim SSItem As VSSItem
Dim TempItem As VSSItem
Dim oVersion As VSSVersion
Dim verDate As Date
Dim User As String
Dim Comment As String
Dim Action As String
' Open SourceSafe database
' NOTE: If your path to srcsafe.ini, username, and password information
' differ from what is listed below, please adjust it accordingly.
SSDB.Open "C:\Program Files\Microsoft Visual Studio\Common\VSS\srcsafe.ini", "Admin", ""
' Get project to search
Set SSItem = SSDB.VSSItem("$/Project_To_Retrieve_History")
' Loop through the Versions collection getting each event
For Each oVersion In SSItem.Versions(VSSFlags.VSSFLAG_RECURSYES)
' Get the action for the current version
Action = oVersion.Action
' Check what the action is and print out what we find.
If InStr(1, Action, "Added", vbTextCompare) > 0 Then
' Get the VSSItem the version contains
Set TempItem = oVersion.VSSItem
' Get the date, username, and comment from the version item.
verDate = oVersion.Date
User = oVersion.UserName
Comment = oVersion.Comment
' Print out the item we have
Debug.Print "Added: " & TempItem.Name & " by " & User & " at " & Format(verDate, "General Date") & Comment
End If
Next
6. Run the program.
7. To implement the workaround mentioned above, paste the following (note that
this is more than just the Command1_Click Sub):
Dim SSDB As New VSSDatabase
Dim SSItem As VSSItem
Dim TempItem As VSSItem
Dim oVersion As VSSVersion
Dim verDate As Date
Dim User As String
Dim Comment As String
Dim Action As String
Dim tItem As VSSItem
Dim oItem As VSSItem
Dim bad As Boolean
Dim sTempItem As VSSItem
Private Sub Command1_Click()
' Open SourceSafe database
' NOTE: If your path to srcsafe.ini, username, and password information
' differ from what is listed below, please adjust it accordingly.
SSDB.Open "C:\Program Files\Microsoft Visual Studio\Common\VSS\srcsafe.ini", "Admin", ""
' Get project to search
Set SSItem = SSDB.VSSItem("$/Project_To_Retrieve_History")
' Loop through the Versions collection getting each event
For Each oVersion In SSItem.Versions(VSSFlags.VSSFLAG_RECURSYES)
' Get the action for the current version
Action = oVersion.Action
' Check what the action is and print out what we find.
If InStr(1, Action, "Added", vbTextCompare) > 0 Then
' Get the VSSItem the current version contains
Set TempItem = oVersion.VSSItem
' Get the date, username, and comment from the version item.
verDate = oVersion.Date
User = oVersion.UserName
Comment = oVersion.Comment
' See if we can use the Items collection
If CheckItem = 1 Then
' If we have a project and the items collection has items, print out each item in the collection.
' We could have an items collection but have 0 items in it, so check for that case.
If TempItem.Type = VSSItemType.VSSITEM_PROJECT And TempItem.Items.Count > 0 Then
' Get the previous version
Set sTempItem = TempItem.Version(TempItem.VersionNumber - 1)
' Loop through the items at this version
For Each tItem In TempItem.Items
bad = False
' Loop through the previous version
For Each oItem In sTempItem.Items
' Check if the names are the same
If oItem.Spec = tItem.Spec Then
' Found the name, not the one we are looking for
bad = True
Exit For
End If
Next
' If this is the file added, print out the information
If bad = False Then
Debug.Print "Added: " & tItem.Name & " in " & TempItem.Name & " by " & User & " at " & Format(verDate, "General Date") & Comment<BR/>
Exit For
End If
Next
Else
' Otherwise just print out the item we have
Debug.Print "Added: " & TempItem.Name & " by " & User & " at " & Format(verDate, "General Date") & Comment
End If
Else
' No items collection, just print out the item we have
Debug.Print "Added: " & TempItem.Name & " by " & User & " at " & Format(verDate, "General Date") & Comment
End If
End If
Next
End Sub
'*****************************************************
' Purpose: Check to see if we can look at the Items
' collection. This keeps us from getting an
' error from SourceSafe.
'
' Inputs: None
'
' Returns: 1 if the Items collection exists and can be used.
' 0 if the Items collection does not exist.
'
'*****************************************************
Private Function CheckItem()
' If we have a problem, go to the error handler
On Error GoTo ErrHandler
' Try to access the Items collection and see if we succeed or not
Dim i As Integer
i = TempItem.Items.Count
' It worked, so return 1
CheckItem = 1
Exit Function
ErrHandler:
' Return 0 - meaning there is a problem
CheckItem = 0
End Function
8. Run the program.
