Q77243: BUG: LinkTimeOut of -1 Waits Only 6553.5 Secs Before Time Out

Article: Q77243
Product(s): Microsoft Visual Basic for Windows
Version(s): 1.0,2.0
Operating System(s):

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Visual Basic Standard Edition for Windows, version 2.0 
- Microsoft Visual Basic Professional Edition for Windows, version 2.0 
- Microsoft Visual Basic Standard Edition for Windows, version 1.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

Contrary to the documentation and online Help for Microsoft Visual Basic,
setting the LinkTimeOut property of a control to -1 will not cause the control
to wait forever for a DDE operation to complete. Setting the LinkTimeOut
property to -1 will cause the control to wait for 65535 intervals of 1/10
second, for a total of approximately 1 hour and 49 minutes.

WORKAROUND
==========

To work around this problem, you can trap the DDE time-out error using the On
Error statement in Visual Basic. If the error was "Timeout while waiting for DDE
response," you can retry the DDE operation until it succeeds. The following is a
code example:

     Sub DDE_Retry_Forever (Source as Control, commandx$)
        On Local Error Goto Handler

        Source.LinkExecute commandx$
        Exit Sub

        Handler:
        If Err = 286 Then
           Resume
        Else
           Error Err
        End If
     End Sub

STATUS
======
