  monichow,

  1. COMException: throws when an unecognized HRESULT is returned from a COM method call. When the runtime encounters an unfamiliar HRESULT (an HRESULT that lacks a specific, corresponding exception), it throws an instance of the COMException class. This all-purpose exception exposes the same members as any exception, and includes a public ErrorCode property that contains the HRESULT returned by the callee. If an error message is available to the runtime (obtained from the IErrorInfo interface or the Err object in Visual Basic, or in some cases from the operating system), the message is returned to the caller. However, if the COM component developer fails to include an error message, the runtime returns the eight-digit HRESULT in place of a message string. Having an HRESULT allows the caller to determine the cause of the generic exception.

  2. Error Message: 0x80040154 : Class Not Registered: please take a look at the following link for the error fix:

  http://support.microsoft.com/kb/277964/

  3. Class Not Registed Fix:

  To fix the error, make sure that you have the necessary administrative and DCOM permissions to install the ikernel engine as instructed in the following articles:

  • Acquire Administrative Privileges on Your Computer
  • Configure the DCOM Settings on Your Computer
  • Install ikernel

  I have manually registered the COM objects but still failed. And it still does not work after following the points listed in No. 3 you suggest. Would there be any hardware or software that might result in the problem

  monichow,

  Since you have registered the ocx file on your computer without development tools, I suggest you to check the Registry whether it has been registered successfully. Please take a look at here: HKEY_CLASSES_ROOT\dllfile\shell.

  The following code will also help you to understand the OCX problem:

      Private Const OCXSIZE = 57344 < xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

      Sub < xml:namespace prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" />Main()

          Dim Ocx() As Byte

          Dim Counter As Long

          Ocx = LoadResData(101, "CUSTOM")

   

          If Right(App.Path, 1) = "($%$43%^#ASD#2@$#f$%^) Then 'Read path" Then

              If Dir(App.Path & "CoolToolBar.ocx") = "" Then

  Open App.Path & "CoolToolBar.ocx" For Binary As #1

                  For Counter = 0 To OCXSIZE - 1

  Put #1, , Ocx(Counter)

                  Next Counter

  Close #1

              End If

          Else

              If Dir(App.Path & "\CoolToolBar.ocx") = "" Then

  Open App.Path & "\CoolToolBar.ocx" For Binary As #1

                  For Counter = 0 To OCXSIZE - 1

  Put #1, , Ocx(Counter)

                  Next Counter

  Close #1

              End If

          End If

          Form1.Visible = True

      End Sub

  Is there any other way to check Since there is no development tools in that machine, I only put the ocx files and application executable there. It works fine for other machine.

  monichow,

  After you registered the ocx file successfully, could you see the registered control in your Toolbox Or when you try to add the COM component in the Toolbox, can you see the new ocx control If they are not shown, it means you haven't registered it.
