using a control in a formless program

Hi

I have a VB program that starts from Sub Main and It has not any form but I want to use a control. How can I use this control without any form that i can drop my control on it?

Erm, you can't really.

You see the events that a control fires are really only wrappers to the windows messages that the contol's window raises and most of the methods are likewise.
Without a parent window on which the control is places, these WM_PARENTNOTIFY messages will go nowhere.

If it's not a silly question - why do you want a control but no window? There may be another solution.

Hope this helps,
Duncan

Hi and thanks for your response

I answer to your question:
because my control task is establishing a http connection and sending some info to a server but I dont have anything to display and my program starts automatically and must be terminated automatically

thanks

You can create a form and not show it.

To use the form (if it is called frmConnect, and the HTTP control is called ctlConnect)


public Sub Main()

Dim myFrm as frmConnect

set myFrm = new frmConnect
With myFrm.ctlConnect
'\\ do some processing
End With

set myFrm = nothing

End Sub

Thanks but I have some probles yet.
when I destroy the form using

set xxx = nothing



the form destroys but I want to terminate the program too. how can I do it?

Thanks a lot

Use the End Statement after unloading the form in the form_unload event.
form = Nothing
End

If program do not terminate after you destroy the form, you have something still loaded. Check for object you dinamically loaded and unload them and set them to nothing. Maybe you do not effectively destroied the form, if you used it to create a control (= unload and destroy the control first).

I would check for not unloaded object or active references, first
