I am trying to display status messages back to the user interface from within a VB activex dll. I tried to show a form and set it to always on top and then change the caption of a label on said form. This worked fine in debug but when compiled VB moaned ad said that only modal forms could be displyed from within an activex dll.
I do not want to Raise Events of these status messages to the calling client GUI. And am loathe to use a modal form as this would mean having to encapsulate the bulk of my code within the status form.
the question is:
How can I show a form from within a dll that does not have to be modal?
thanks
Steve

rauchs,
Why do you not to Raise Events?
I completly agree with you on the modal form issue.
You can check out July 2000 issue of Visual Basic Programmers Journal. Bill MacCathry has an article on using pointers in VB to share data between apps.
The only other thing I can think of is to poll the DLL from a Timer, but this seems worse than raising events.

INFO: Non-Modal Form Support in Visual Basic DLLs
I've got a simpler solution for you. Pass a reference to a Label control that is in your UI to the Active-X DLL and let it update the caption. That way, you don't have to display any forms in the Active-X DLL, or in the UI, you could use the Microhelp in a status bar, or you could display a non-modal form in your UI and pass a reference to a label on it.
In your UI
frmFeedback.show
rc = myObj.MyMethod (frmFeedback.lblPercent)
Unload frmFeedback
In your ActiveX DLL
MyMethod(ctl as Control)
for i = 0 to 1000
ctl.Caption = i & " Percent"
ctl.Refresh
Next i

Try the ShowWindow API with the SW_NORMAL (do not remember if that's the exact name. Check it in the API Viewer) constant.
