WD97: Run-Time Error '4599' Using DDE to Internet Explorer 4.x

ID: Q178879

The information in this article applies to:

SYMPTOMS

In versions of Microsoft Internet Explorer earlier than Microsoft Internet Explorer version 4.x, dynamic data exchange (DDE) commands could be used to extract the Uniform Resource Locator (URL) address from the browser. For instance, the following sample Microsoft Visual Basic for Applications code would display the URL address in a message box:

   Sub ShowUrl()
      IEchannel = DDEInitiate("iexplore", "www_getwindowinfo")
      Info = DDERequest(IEchannel, "dogetwindowinfo")
      MsgBox Info
      DDETerminateAll
   End Sub

This code no longer works with Microsoft Internet Explorer version 4.x and returns the following error message:

   Run-time error '4599': Process failed in other application

The following sample Visual Basic code displays the URL address for each window displayed in the Microsoft Internet Explorer browser:

   Sub FindIE40Url()
      Dim IEWindows As New SHDocVw.ShellWindows
      Dim oIE As SHDocVw.InternetExplorer
      On Error GoTo errorhandler
      For Each oIE In IEWindows
         MsgBox "Caption: " & oIE.LocationName & vbCr & "URL: " _
            & oIE.LocationURL
      Next
   errorhandler:
      If Err <> 0 then
         MsgBox " Microsoft Internet Explorer must be running" _
            & " for this code to work."
      End If
   End Sub

Note: For this code to work, you must reference the "Microsoft Internet Controls." To add the "Microsoft Internet Controls" reference, follow these steps:

1. In the Visual Basic Editor, click References on the Tools menu.

   The References dialog box shows all object libraries and projects that
   are registered with the operating system.

2. In the Available References list, scroll down to find "Microsoft
   Internet Controls."

3. Click to select the "Microsoft Internet Controls" check box, and then
   click OK.
