Replied by support on topic UaHostAndEndpointDialog do not appear

Hello.

I have tried to reproduce it, but so far with no success.
In order to get us to the same starting line, can you please download the latest build of QuickOPC (from www.opclabs.com/products/quickopc/downloads , it should be 5.41.1274.1 or later), reinstall it, rebuild your projects with the new assemblies, and retest?

Thank you

1. QuickOPC UA DLL verion : 5.41.524.1
2. VS 2015
3. VB.NET
4. Only drag and drop the EasyUAClient and the UaHostAndEndpointDialog
5.

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As EventArgs) Handles Button2.Click
        If UaHostAndEndpointDialog1.ShowDialog = DialogResult.OK Then
            TextBox5.Text = UaHostAndEndpointDialog1.EndpointDescriptor.UrlString
        End If
    End Sub

When I push the Button2 the SW freez. If I debug, the SW flow stop in the .ShowDialog freez. Sometimes the complete development environet freez.

I tried it on differetn machines, worked same.
So every time If i start from a balnk project is work fine. But is I try to modify an older project it will not work.
I made a test. My old Project not worked. I made a new one, copy everithing from the old to the new, it is working.

Hello. This is difficult to troubleshoot without having a way to reproduce it here. Can you please answer following questions:

Which version of QuickOPC are you using?
Which version of Visual Studio are you using?
Which programming language?
How do you add the dialog to the project? Just by instantiating the UAHostAndEndpointDialog from the code? Or do you drag the dialog from the Toolbox to the form?
At which point the dialog "does not appear"? Are you referring to a ShowDialog() method call, or a different moment?

Thank you

UaHostAndEndpointDialog do not appear was created by Laci

When I create a new program, add everything what is need to UA, the UaHostAndEndpointDialog appear correctly.

But when I try to add UA to and older project (still dotNet 4.5.2) I do everything same like before, the dialog box will not appera and the program frozen.
After some try, the Visual Studio also freez.

What can be the problem?
