device.Setup()
device.Setup()
Setup Opens and closes imediatly.
If I comment out the _deviceManager.Devices.Current.Close(); and _deviceManager.Close(); it stays open until I close it....Problem is, I'm leaving the device open and I don't want to.
//Scanner Settings
_deviceManager.Open();
if (_deviceManager.Devices.Count > 0)
{
if (_deviceManager.Devices.Select())
{
// get reference to current device
_device = _deviceManager.Devices.Current;
_device.Open();
_device.Setup();
}
_deviceManager.Devices.Current.Close();
}
else
MessageBox.Show("No Compliant Devices!");
// close the device manager
_deviceManager.Close();

Re: device.Setup()
I understand But there is no event or way of knowing when the setup dialog is closed.
Re: device.Setup()
I understand But there is no event or way of knowing when the setup dialog is closed.You need to subscribe to the StateChanged event of the Device class if you want to know when device is closed.
Device is enabled when the setup dialog is opened, device is opened when the setup dialog is closed.
Best regards, Alexander
