How can I buffer selected pros?

DavidMrázek

Good day,
how can I trim the buffer layer 200 meters around, then save it in the auxiliary layer. My code attempt:

protected override async void OnClick()
{
await OnSketchCompleteAsync();
}
protected async Task<bool> OnSketchCompleteAsync()
{
var valueArray = await QueuedTask.Run(() =>
{
FeatureLayer fl = MapView.Active.Map.FindLayers("O_Klad_ZTM10").First() as FeatureLayer;
QueryFilter qf = new QueryFilter();
string whereClause = "ZTM10_nom LIKE '0602%'";
qf.WhereClause = whereClause;
var g = new List<object>();
using (RowCursor rowCursor = fl.Search(qf))
{
while (rowCursor.MoveNext())
{
g = new List<object>() { fl.Select(qf) };
}

}

return Geoprocessing.MakeValueArray(g, null, @200 Meters);// HERE CODE SHOWS ERROR
});
await Geoprocessing.ExecuteToolAsync("analysis.Buffer", valueArray);
return true;
}

 

 If I haven't explained it enough, ask me.

 

Thank you very much for the advice

Hi,

As I understand from your first question  you need code like this:

 

protected override async void OnClick()
{
	FeatureLayer fl = MapView.Active.Map.FindLayers("O_Klad_ZTM10").First() as FeatureLayer;	
	if (fl == null)
		return;

	QueuedTask.Run(() = >
	{
		QueryFilter qf = new QueryFilter();
		string whereClause = "ZTM10_nom LIKE '0602%'";
		qf.WhereClause = whereClause;
		fl.Select(qf)
	});

	var rozsah = 200;
	CalculateBuffer(fl, @"C:\Users\mrazekd\Desktop\ukoly\ProAppModule1\buffers.shp", rozsah, "Meters");
}

You need to check asynchronous things. of that code
