Access Denied in dll

Access Denied in dll

Access Denied in dll


I have used err.raise method(VB com) in dll and kept it in
COM+, At server side it gives me proper error message, but
at client side I get the message method "methodname~" of  object "ObjName~" failed. If I log the information there I get the error message access denied(it happens while accessing err.number, err.description And err.raise method)

What is the problem, why its not working.

Since a long time I am not getting help for this prob.
At least if some of one could give me some clue, will be helpful.


RE: Access Denied in dll

There are two Microsoft knowledge base articles about this issue - Q255733 and Q255735. The problem is supposedly fixed in Windows 2000 SP1.

Hope this helps.

RE: Access Denied in dll

After installing Service Pack2  as suggested by Microsoft I am getting proper error message at client side.

There is another problem. One of the method of my dll implemented in COM+ is as follows and I am getting error "Access Denied at errobj.number
What is the reason?

Public Sub HandleErr(errObj as object)

'This parameter is passed as err object

dim i as integer
'and some variable declaration

if errobj.number = 1 then   ' here I am getting error
   'some code

end sub

RE: Access Denied in dll

I don't know why you are getting the error, but I'd try passing a copy of the Err object and using early instead of late binding. See the red bits below:

Sub Whatever()
On Local Error GoTo ErrorHandler:
Err.Raise 1

Dim MyErr As ErrObject
Set MyErr = Err
HandleErr MyErr

End Sub

Public Sub HandleErr(errObj As ErrObject)
If errObj.Number = 1 Then
  'some code
  'some more code
End If
End Sub
