/Instance parameter

I notice in the history section that you refer to an /Instance command line parameter which doesn`t appear to be documented. Does this allow us to start more than one instance of OEEE at the same time? Could you post some details please.

THanks

Yes, this is true - /Instance allows you to start several Offline Explorer instances at the same time.

Hi Oleg,

I wish You an happy new year!

now my question:

is it possible to start many instances of oee via ole?
if yes: do you have maybe an example (VB or C#)
if no: is it possible to implement it?

I need to start oee with 2 paramters: /hWnd=xxx /Instance

Thank You

It is easy. I usually start using ShellExecute API function and pass parameters to the executable.

Yes of course!
But how to get the COM-Interface from the individual apps?
Oleg Chernavin 01/10/2008 07:37 am
I am afraid, it is impossible to do. At least, I do not know how to do this.

But why do you need multiple instances?

because i want to download only one project pro instance!

when downloading more than one project at the same time and if something goes wrong with the download of one project (sometimes happens that oee hangs) all the other downloads and also my application are involved on this situation. If I start a new process with a new instance of oee for each download, I can if necessary kill just this one process and everything goes on.

But I have already found a solution for the problem: I do not need the COM-IF of the "downloading-instance"

Do You see some problems on doing it on this way?

It is safe to run many instances. Except one thing - if you make changes to the Projects, the changes may be lost, because Offline Explorer writes webdown.dat when it closes. And if you make run instances 1 and 2, make changes in 1 and close it, instance 2 will overwrite it when it is closed.

Hi Oleg,

it works fine, because Ido not make changes on the project properties on the "downloading instance".

But I have a question:

when starting the oee with the parameter /Close you show a message box "Countdown" before closing.
Is it possible the this messagebox is not shown if the parameter /Minimize is active?

Thank You

You may use /CloseNoCountdown for this.

Hi Oleg,

I need two or more instances: one for OLE-comunication and x for downloading process. Is it possible the the changes which only are done in the OLE-Instance will be written down, so that the instances which starts after the changes can concider them even the OLE-instance is running? It could be a OLE-command to write the changes down!

I hope you can help

Thank You

Yes, IMainOE.SaveChanges does that.
