"Catastroph ic failure" / "Catastroph ic error" accessing ActiveX Object

[jdanoz]

Hello,

i have a vb.net project with a reference to an ActiveX object (ocx).
If i try to use the ocx from vb6 project (adding the reference) it
works ok (using CreateObject).

In vb.net,

the CreateObject works ok, the object gets initialized...

but when i try to run an object method or change an object property
vb.net raises an InteropServices .COMException.. . "Catastroph ic Error /
failure"...

The app type is console.

If i create a windows forms application and i add the ocx reference by
adding this one to the toolbar (personalize toolbar components)... it
runs ok using the name of the object dropped to the windows form.

But i can't use CreateObject for initialize the ocx object... and i
need to do this...

Any sugestions will be appreciated...

Thanks in advance,

Jorge.

late binding in VB.Net requires some extra coding as in VB6 ( 2 lines extra
to be exact :-)

i do this wich works fine in my situation ( late binding to an VB6 Activex
executable )

Imports System.Reflecti on

Private HBSObject As Object
in my form load

Dim HBSCOM As Type

'Get the object

HBSCOM = Type.GetTypeFro mProgID("Hbase. clsHbase")

'Create instance of HBSCOM

HBSObject = Activator.Creat eInstance(HBSCO M)

in my cleanup routine

System.Runtime. InteropServices .Marshal.Releas eComObject(HBSO bject)

HBSObject = Nothing

hth

let us now if this did the trick
