Hi fellow group members,

GoodMorning.

I want to send a specific error from my VB component(server) to a VC component(client) using err.raise method. But, I am not able see the value in hr(HRESULT) of VC. Please advise.

Sample code in VB:
Private sub IF1_Method1()
On Error Resume Next
Call Mathod2
If Err.Number < 0 Then 'if it is error
'send my error
Err.Raise 1000+vbObjectError
Exit sub
End If
End sub

Sample code in VC
hr = pIF1->Method1()

Here “hr” is always found to be “zero” though I make sure to send an error from VB.


 
As far as I know, you won't be able to, since err.raise only sets values in an internal Err object for VB, which object isn't exposed via COM. Some recommendations are to make the error into a property, to raise an event, and so on. I believe there's a way to make an error visible to a C HR, but I'm not sure how. You might repost this to the VB5 and 5 forum, where there are people who know the API very well.
