I have a VB6 Outlook Add-in that has been in production. I tried migrating it

to Vb.Net. Now I get this error "Non-modal forms cannot be displayed in this

host application" when I execute this code:

Dim oSetup As frmSetup

oSetup.ShowDialog() 'error here

What is the work-around please?
 
There's something else going on, ShowDialog() is a modal call, not

non-modal. To display the form non-modally you would call Show(), not

ShowDialog().

You do get an error if you try to show a non-modal form when a modal form is

open, but that's not the case here.

In what context is this dialog being displayed? Are any other forms open

either modally or non-modally?

Does it make a difference at all if you structure your code like this?

Dim oSetup As New frmSetup

oSetup.ShowDialog()

The code is for showing a dialog box much like when you click on

Help...About. Originally, the code was oSetup.Show in VB6.

But after migrating the project to VB.Net, I got an error on this line and I

got a suggestion to use oSetup.ShowDialog() and setting the Owner property of

the form to Support UI Automation. So the question i posed was "What is the

code for setting the Form.Owner's property to support UI Automation?"

There's no setting I know of that sets an form Owner property to support UI

automation, I have no idea what you're talking about. You set a form owner

to another form or to the window handle of some application's window, such

as the main Outlook window or an Inspector window.

Usually that's not at all necessary however, unless in a special case such

as with WordMail and the dialog you are showing is coming up under the

WordMail window and using the usual methods for setting z-order aren't

working.
