Hi all,

I am getting the following message from a user's machine after my application is installed:

Failed to load control 'Http" from DartWeb.dll. Your version of DartWeb.dll may be outdated. Make sure you are using the version of the control that was provided with your application.

I ran the Dart Diagnostics tool to generate the following report. It seems like the latest Dart related DLLs were used:

Hi Ken,
Is this problem isolated to your app, or do you see the same error when a sample is run on this machine?

I assume you have tried unregistering, and re-registering the dlls? And re-booting?

Thanks,

Hi Ken,

We tried un-reg and reg of all DLLs and the problem still exists. I haven't try to run a sample app because we don't have direct access to the user's machine. We currently have about 50 users but only one user reported this problem.

Thanks,
Ken

In what development environment is the Http control being created? (Example VB6, Delphi, ASP) What is the exact code that is used to create it?

My application is a standalone VB6 application. The HTTP control is placed in a form container which is wrapped by a class with the

 Private WithEvents m_http As Http

statement and the following initialization code

Private Sub Class_Initialize()
  ' the form container
  Set m_ctlsForm = New ControlsForm
  Set m_http = m_ctlsForm.http1
  ...
End Sub

All HTTP transactions (GET/POST) were done by using the m_http member.

Thanks,
Ken

There has to be something weird in OLE / COM system for that one particular users machine. I would suggest doing the following to make sure that everything is clean:

1) Close all apps and services that might be using the Dart DLL's

2) Search the ENTIRE system for Dart*.dll and Dart*.oca and delete anything that you find

3) Reboot to ensure all cached info is flushed

4) Reinstall your app so that the Dart DLL's that are registered are yours and yours only.

If that does not solve the problem, then I suggest you call in and open a support incident.
