FIX: Errors from Project Differences Window (235606)

SYMPTOMS

Subfolders appear in the wrong place in the Project Differences window. SubFolders are interspersed with files in alphabetical order, rather than appearing underneath the file list.

This can cause errors on operations done in the Project Differences window such as Get, Checkout, Checkin, Show Differences and Add. The following error messages may appear:

"$/<Project> is not an existing filename or project"

"File <filename> is invalid. File may not begin with $.

"$/<filename> not found"

CAUSE

In Visual SourceSafe 6 functionality was extended to allow file system and SourceSafe information to appear in either pane. This allows project to project comparisons and directory to directory comparisons. SourceSafe operations (for example, get, add, checkout, and so forth) are only allowed when the diff included both projects and working directories, but the file system information can be on the left and the SourceSafe information on the right. This scenario was not allowed in Visual SourceSafe 5. Most of the code defects found involved assumptions carried over from Visual SourceSafe 5 about which pane was associated with file system or SourceSafe information.

Steps to Reproduce Behavior

Create the following directory structure on the Hard Drive:
   c:\myfiles
           \sub1
                \bsub
In the sub1 directory create the files:
    Bfile.txt
    Cfile.txt
    Dfile.txt
    Efile.txt
In VSS create the following project structure:
$/myfiles
/sub1
Set the working folder of $/myfiles to C:/myfiles, then add all the files from C:\myfiles\sub1 to $/myfiles/sub1, except Efile.txt.
In the project pane of the VSS Explorer, right-click on $/myfiles, and choose Show differences from the shortcut menu. Select the Recursive checkbox, and click OK.

Note that in the right-pane of the Differences window C:\myfiles\sub1\bsub appears between the files Bfiles.txt and Cfiles.txt.
As a result:

Attempting a Get or Checkout operation from the right-pane will return:
"$/myfiles/<file> is not an existing filename or project."
Showing differences of any file underneath C:\myfiles\sub1\bsub will return:
"File 'C:\myfiles\sub1\bsub\<filename>' not found."
Attempting to add Efile.txt from the right pane will return the same error as ii), and attempting to add it from the left pane will return:
"File $/myfiles/sub1/Efile.txt is invalid. Files may not begin with $."

Additionally,the Differences report will display Efile.txt as belonging in the myfiles\sub1\bsub directory. Other problems, such as the Differences window not refreshing correctly are associated with this bug. To reproduce this:

Create a new file (AAFile.txt) in the C:\myfiles\sub1 folder.
Display the Project differences for $/myfiles/sub1, choosing the Recursive option.
From the right-pane of the Differences window, add AAFile.txt.

Note that the left-pane does not automatically refresh to show that AAFile.txt is now in the project.
