'Diff Doc'TM ActiveX Interface

(The Comprehensive Document Comparison Tool)


Using 'Diff Doc' as an ActiveX Component

For COM+ (i.e. with IIS) users click here.

One very important note is that DiffDoc.EXE is both an executable application AND an ActiveX component.  That is, the file, DiffDoc.EXE, can be ran as a stand alone application, and, can be referenced as a component within your development environment.

First, be sure to uninstall any previous versions of 'Diff Doc' before using the ActiveX version. Next, install.

Directly below is some VBS (Visual Basic Script). You could put the following 3 lines in a text file, call it TEST.VBS and give it a go:

set converter = WScript.CreateObject("DiffDoc.clsDiffDoc")
result = converter.DoCommandLine("/SC:\IN\Tryme.txt /MC:\IN\Tryme2.txt /X /V")

For Visual Basic users, simply make a reference to the DiffDoc.EXE application in the Tools\References menu item. Once done you now have access to the DiffDoc component.

Here is some sample code illustrating its usage:

Clich HERE to download the VB.NET demo.

Private Sub Command1_Click()
Dim dd As DiffDoc.clsDiffDoc

Set dd = New DiffDoc.clsDiffDoc
dd.Key = "" ' Assign Key To the 'Final Key', given upon registration.

' Run by the command line. See 'Diff Doc' documentation for a full listing of
' switches and options.
lRetVal = dd.DoCommandLine("/SE:\Delme\Test1.txt /ME:\Delme\Test2.txt /TE:\Delme\ReportOut.DOC /F1 /R4 /X ")

' DoCommandLine() Return Values
' 0 = Success
' -1 = Shareware expired
' -2 = Command line String Emtpy or invalid.
' -3 = Missing required command line argument(s)

If (lRetVal = 0 And dd.NumDifferencesFound > 0) Then
  Call ShellExecuteAny(Me.hwnd, "open", "E:\Delme\ReportOut.DOC", ByVal 0&, ByVal 0&, 4)
End If

Set dd = Nothing ' Closes 'Diff Doc' application
End Sub

As you can see from the code above, the ActiveX wrapper simply wraps the command line feature. So, to learn what you can do with the ActiveX, please refer to the 'Using the Command Line' section of the 'Diff Doc' users manual.  Also, you will have to change the path information in the DoCommandLine() method for your particular set of files you are comparing.



      This function emulates doing the command line, but through the COM interface.

         0 = Success
        -1 = Shareware expired
        -2 = Command line String Empty or invalid
        -3 = Missing required command line argument(s)


       Returns the number of differences found while doing a comparison of files or folders.
