Problem with DLL in Windows 2003

[rcaetano]

Hi,

I have a component(dll) that calls another component(dll), but i am getting the error "429 - cannot create object" when i call a method. For Example:

In the DLL that calls another DLL

Implements ObjectControl
Private objContext As ObjectContext
 
Public Const objNotaFiscal As String = "SynchroBusiness.cNotaFiscal"
 
Dim oINotaFiscal As INotaFiscal
 
Set oINotaFiscal = objContext.CreateInstance(objNotaFiscal) [COLOR=Red]'the error occurs here[/COLOR]
Call oINotaFiscal.CalculateTaxes(SendMsg, replyMsg, ErrorMsg)

SynchroBusiness.dll is installed in COM+


This error just occurs in Windows 2003.
In Windows 2000 the components are working fine.

Can anyone help?

Thanks
Roberto

objContext hasn't been instanciated....

ok... but... why is it working in Windows 2000?

if I put

Set objContext = New ObjectContext

occurs the Compile Error "Invalid use of New keyword"

I have encountered a similar issue. I have created a COM dll in VB6. It works fine in XP, however on Windows Server 2003 I receive "ActiveX component can't create object" when trying to instantiate it.

In a VB6 .exe to test the .dll, I have tried using:

Dim myDLL As Object
Set myDLL = New My_COM_Security.Dim_Sec

and

Dim myDLL As New My_COM_Security.Dim_Sec

Both methods to instantiate the .dll return the same error. The VB6 .dll is a simple 19 line function that calls a VB.NET .dll exposed to COM. I can instantiate the .NET .dll just fine from the VB6 .exe and know that it is simply an issue of not being able to instantiate the VB6 .dll.
