Build application using GMap.Net in C# with offline maps

I'm trying to download a MapProvider to use offline map but i dont know how to download.
it works when i use ServerOnly.
This is my code:
GMap.NET.GMaps.Instance.Mode = GMap.NET.AccessMode.ServerOnly;
_map = new GMapControl();
Map.MapProvider = GMap.NET.MapProviders.BingHybridMapProvider.Instance;
Map.DragButton = MouseButton.Left;
Map.MinZoom = 2;
Map.MaxZoom = 18;
Map.Zoom = 5;
Map.CanDragMap = true;
Map.Position = new GMap.NET.PointLatLng(48.8589507, 2.2775175);
Map.ShowCenter = false;
Thank you everyone

You can cache the map in the local storage using the ServerAndCache found in GMap.NET.AccessMode
The following function will do the work:
private void gMapStoreOffline(int lat, int lng)
{
gMapControl1.MapProvider = GMap.NET.MapProviders.BingMapProvider.Instance;
GMap.NET.GMaps.Instance.Mode = GMap.NET.AccessMode.ServerAndCache;
GMap.NET.MapProviders.OpenStreetMapProvider.UserAgent = "IE";
gMapControl1.MapProvider = GMap.NET.MapProviders.OpenStreetMapProvider.Instance;
GMaps.Instance.OptimizeMapDb(null);
// Define the location to cache the file
gMapControl1.CacheLocation = #"C:\Users\<username>\..";
gMapControl1.Zoom = 14;
gMapControl1.Size = new Size(this.Width, this.Height);
gMapControl1.ShowCenter = false;
gMapControl1.Position = new GMap.NET.PointLatLng(lat, lng)
}

requests[0]' (oneof), oneof field 'kind' is already set. Cannot set 'updateCell encountered when generating checkbox

I'm trying to generate a checkbox from C#.net using google sheets API but I'm encountering the oneof field kind is already set error. I tried combining extendedValue and DataValidation. Please see code snippet below:

How do I use AWS SDK for .Net to create an image to an instance I have? (AMI)

I have an Amazon EC2 instance and I need to be able to create an AMI (image) from it programmatically. I'm trying the following:
CreateImageRequest rq = new CreateImageRequest();
rq.InstanceId = myInstanceID;
rq.Name = instance.KeyName;
rq.Description = "stam";
rq.NoReboot = true;
IAmazonEC2 ec2;
AmazonEC2Config ec2conf = new AmazonEC2Config();
ec2 = AWSClientFactory.CreateAmazonEC2Client(ec2conf);
// CreateImageResponse imageResp;
Amazon.EC2.Model.CreateImageResponse imageResp = null;
try
{
imageResp = ec2.CreateImage(rq);
}
catch (AmazonServiceException ase)
{
MessageBox.Show(ase.Message);
}
The result is always an AmazonServiceException saying that there is a NameResolutionFailure.
How do I overcome this? I tried different possible "name" possibilities but cannot find the right one.

string amiID = ConfigurationManager.AppSettings[AmazonConstants.AwsImageId];
string keyPairName = ConfigurationManager.AppSettings[AmazonConstants.AwsKeyPair];
List<string> groups = new List<string>() { ConfigurationManager.AppSettings[AmazonConstants.AwsSecurityGroupId] };
var launchRequest = new RunInstancesRequest()
{
ImageId = amiID,
InstanceType = ConfigurationManager.AppSettings[AmazonConstants.AwsInstanceType],
MinCount = 1,
MaxCount = 1,
KeyName = keyPairName,
SecurityGroupIds = groups,
SubnetId = ConfigurationManager.AppSettings[AmazonConstants.AwsSubnetId]
};
RunInstancesResponse runInstancesResponse = amazonEc2client.RunInstances(launchRequest);
RunInstancesResult runInstancesResult = runInstancesResponse.RunInstancesResult;
Reservation reservation = runInstancesResult.Reservation;

Problem eventually solved!
it turned out thyat some codelines were doing things which were already done already and removing this part:
IAmazonEC2 ec2;
AmazonEC2Config ec2conf = new AmazonEC2Config();
ec2 = AWSClientFactory.CreateAmazonEC2Client(ec2conf);
// CreateImageResponse imageResp;
Amazon.EC2.Model.CreateImageResponse imageResp = null;
Made things clearer and no wrong repetitions happened! Now it works!

Xamarin - Video Cropping for iOS

I was wondering if there was a way to crop videos in Xamarin. I can't seem to find any examples. I tried looking at the existing functions and Classes but I couldn't find anything.
Basically make square videos like what Vine and Instagram have. I think this is done by cropping out the rest of the video and not just zooming in.

I find part of the code from one source, I tried to add owner but I could not find. The solution's key part is added by me for cropping which is "VideoCleanAperture" inside AVVideoSettingsCompressed.
videoUrl = ((AVFoundation.AVUrlAsset)avAsset).Url;
NSError assetReaderError;
var assetReader = AVAssetReader.FromAsset(avAsset, out assetReaderError);
var assetTrack = avAsset.Tracks.First();
//Height = (System.nint?)avAsset.NaturalSize.Height,
//Width = (System.nint?)avAsset.NaturalSize.Width,
var inputSettings = new AVVideoSettingsUncompressed()
{
Height = (System.nint?)avAsset.NaturalSize.Height,
Width = (System.nint?)avAsset.NaturalSize.Width,
};
var assetReaderOutput = new AVAssetReaderTrackOutput(assetTrack, settings: inputSettings);
assetReaderOutput.AlwaysCopiesSampleData = false;
string tempFile = Path.Combine(Path.GetTempPath(), "CroppedVideo.mp4");
if (File.Exists(tempFile)) File.Delete(tempFile);
var url = NSUrl.FromFilename(tempFile);
NSError assetWriterError;
var assetWriter = new AVAssetWriter(url, AVFileType.Mpeg4, out assetWriterError);
var outputSettings = new AVVideoSettingsCompressed()
{
Height = 300,
Width = 300,
Codec = AVVideoCodec.H264,
CodecSettings = new AVVideoCodecSettings()
{
AverageBitRate = 1000000,
VideoCleanAperture = new AVVideoCleanApertureSettings(
new NSDictionary(
AVVideo.CleanApertureWidthKey, new NSNumber(300),
AVVideo.CleanApertureHeightKey, new NSNumber(300),
AVVideo.CleanApertureVerticalOffsetKey, new NSNumber(10),
AVVideo.CleanApertureHorizontalOffsetKey, new NSNumber(10)
)
)
},
ScalingMode = AVVideoScalingMode.ResizeAspectFill
};
var assetWriterInput = new AVAssetWriterInput(mediaType: AVMediaType.Video, outputSettings: outputSettings);
assetWriterInput.ExpectsMediaDataInRealTime = false;
assetWriter.AddInput(assetWriterInput);
assetWriter.StartWriting();
assetReader.AddOutput(assetReaderOutput);
assetReader.StartReading();
assetWriter.StartSessionAtSourceTime(CoreMedia.CMTime.Zero);
var mediaInputQueue = new DispatchQueue("mediaInputQueue");
assetWriterInput.RequestMediaData(mediaInputQueue, () =>
{
while (assetWriterInput.ReadyForMoreMediaData)
{
var nextBuffer = assetReaderOutput.CopyNextSampleBuffer();
if (nextBuffer != null)
{
assetWriterInput.AppendSampleBuffer(nextBuffer);
}
else
{
assetWriterInput.MarkAsFinished();
assetWriter.FinishWritingAsync();
assetReader.CancelReading();
assetReader.Dispose();
assetReaderOutput.Dispose();
assetWriter.Dispose();
assetWriterInput.Dispose();
break;
}
}
});
}

Bing API ".Count" property not working?

I have been trying to bring back 20 results of images using the Bing API. Here's the code:
SearchRequest request = new SearchRequest();
request.AppId = APPID;
request.Query = HttpUtility.HtmlEncode(searchQuery);
request.Sources = new SourceType[] { SourceType.Image };
request.Image = new ImageRequest();
request.Image.Count = 20;
request.Image.Filters = new string[1] { "Size:Medium" };
Now everything on here works, including the Image.Filters property. Just not the Count property. Is there a known bug or am I just missing something here?

I'm not sure really sure about this but I think you are missing setting CountSpecified property. Try this
request.Image = new ImageRequest();
request.Image.Offset = 0;
request.Image.Count = 20;
request.Image.CountSpecified = true;
request.Image.Filters = new string[1] { "Size:Medium" };
