    <zxing:ZXingScannerView Grid.Row="1" x:Name="_scanView" OnScanResult="Handle_OnScanResult" IsScanning="true" WidthRequest="200" HeightRequest="200"  />

You can do it in the Options which is of type MobileBarcodeScanningOptions. That has a property called UseFrontCameraIfAvailable.



To set it from code, do this: _scanView.Options = new MobileBarcodeScanningOptions { UseFrontCameraIfAvailable = true; }



From XAML is a bit more extensive but not undoable:



<zxing:ZXingScannerView Grid.Row="1" x:Name="_scanView" OnScanResult="Handle_OnScanResult" IsScanning="true" WidthRequest="200" HeightRequest="200">

    <zxing:ZXingScannerView.Options>

        <zxcore:MobileBarcodeScanningOptions UseFrontCameraIfAvailable="true" />

    </zxing:ZXingScannerView.Options>

</zxing:ZXingScannerView>


You might need to import a different XAML namespace for the options object. I don't have an actual project at hand to try, but I'm sure you will figure that one out.

            SQL update select statement

            0 I'm trying to update an entry in my database (postgresql). I'm having a problem with updating the query: INSERT INTO prices (price, product_id) SELECT product_price, commn_id FROM products_temp as prod WHERE NOT EXISTS (SELECT * FROM prices od WHERE prod.commn_id = od.product_id) OR prod.product_price != ( SELECT price FROM prices as p WHERE p.product_id = prod.commn_id order by p.end desc LIMIT 1 ) Query works fine when i delete: OR prod.product_price != ( SELECT price FROM prices as p WHERE p.product_id = prod.commn_id order by p.end desc LIMIT 1 ) So it seems to me that it's looping through this operation.
