Hello, I'm not a TestStand programmer so I don't know how NotifyStartOfModalDialogEx works, but I'm quite sure your WPF should be linked to the parent (that should be TestStand) to have a chance to be modal (like in the code from codeproject).
I would also modify the code this way:
public static void ShowSerialDialogWPF(SequenceContext seqContext, out string serialNumber, out bool continueTesting)
{
...
using(SerialDialog userInterfaceDialog = new SerialDialog())
{
System.Threading.Thread uiThread = new System.Threading.Thread(() =>
{
userInterfaceDialog.ShowDialog();
});
uiThread.SetApartmentState(System.Threading.ApartmentState.STA);
uiThread.Start();
uiThread.Join();
serialNumber = userInterfaceDialog.Serial;
continueTesting = userInterfaceDialog.ContinueTesting;
}
...
}
HAGD
