I am working on a wp8 project and need to find the location . I've used windows.device.geoloaction name space to find the lattitude and longitude now I need to find the address(country state and zip). I found this example but I am confused how to pass the coordinates that I obtained . Here is my code.
public async void FindTADeviceLocation()
{
////Declare Geolocator object
Geolocator geolocator = new Geolocator();
// Set user's accuracy
geolocator.DesiredAccuracy = PositionAccuracy.High;
//get the position of the user.
try
{
//The await guarantee the calls to be returned on the thread from which they were called
Geoposition geoposition = await geolocator.GetGeopositionAsync(
maximumAge: TimeSpan.FromMinutes(1),
timeout: TimeSpan.FromSeconds(10)
);
var geoQ = new ReverseGeocodeQuery();
geoQ.QueryCompleted += geoQ_QueryCompleted;
if (geoQ.IsBusy == true)
{
geoQ.CancelAsync();
}
// Set the geo coordinate for the query
geoQ.GeoCoordinate = geoposition.Coordinate;
geoQ.QueryAsync();
}
catch (Exception ex)
{
if ((uint)ex.HResult == 0x80004004)
{
MessageBox.Show("position is unknown");
}
}
}
void geoQ_QueryCompleted(object sender, QueryCompletedEventArgs<IList<MapLocation>> e)
{
if (e.Result.Count() > 0)
{
string showString = e.Result[0].Information.Name;
showString = showString + "\nAddress: ";
showString = showString + "\n" + e.Result[0].Information.Address.PostalCode + " " + e.Result[0].Information.Address.City;
showString = showString + "\n" + e.Result[0].Information.Address.Country + " " + e.Result[0].Information.Address.CountryCode;
showString = showString + "\nDescription: ";
showString = showString + "\n" + e.Result[0].Information.Description.ToString();
MessageBox.Show(showString);
}
}
I know the problem is in the line geoQ.GeoCoordinate = geoposition.Coordinate;
But how can I pass the coordinates to geoQ.GeoCoordinate?
Thanks in adwance
This is done. The geocordinate takes arguments of the type double. so all we've to do is to convert the cordiantes into double and pass it.
var currentLocationLatitude = Convert.ToDouble(geoposition.Coordinate.Latitude.ToString("0.0000000000000"));
var currentLocationLongitude = Convert.ToDouble(geoposition.Coordinate.Longitude.ToString("0.0000000000000"));
var geoQ = new ReverseGeocodeQuery();
geoQ.QueryCompleted += geoQ_QueryCompleted;
if (geoQ.IsBusy == true)
{
geoQ.CancelAsync();
}
// Set the geo coordinate for the query
geoQ.GeoCoordinate = new GeoCoordinate(currentLocationLatitude, currentLocationLongitude);
geoQ.QueryAsync();
Thanks

I have some code that generates a PDF. For some reason there is a black bordered cell showing up behind the image on this line:
sb.AppendLine("<tr><td>" + "~/images/Products/" + imageName + "</td><td>~/images/spacer.gif</td></tr>");
I have tried setting the border to 0 on the table, but I'm getting an error ") expected", or the html just breaks.
How can I ensure that there is no border shown around this cell?
Here are the two parts involved:
//add images
str = new StringBuilder();
str.Append("<table>");
if (HasRelatedImages(ContentId, ref str))
{
obj = new List<FieldIdentifier>();
obj.Add(new FieldIdentifier() { LabelName = "Images", Value = "" });
index = index + 1;
rows.Add(index, obj);
obj = new List<FieldIdentifier>();
obj.Add(new FieldIdentifier() { LabelName = "NewTable_Data", Value = str.Append("</table>").ToString() });
index = index + 1;
rows.Add(index, obj);
}
//end images
and
private Boolean HasRelatedImages(long productId, ref StringBuilder sb)
{
var imagemetadata = new List<ImageMetadata>();
int i = 0;
try
{
Database db = DatabaseFactory.CreateDatabase("Site.DbConnection");
DbCommand dbCommand = db.GetStoredProcCommand("[spSelectImages]");
db.AddInParameter(dbCommand, "#ContentID", DbType.Int64, productId);
IDataReader dr = db.ExecuteReader(dbCommand);
while (dr.Read())
{
string imageName = GetNullableDBStringValue(dr["ImageName"]);
string altText = GetNullableDBStringValue(dr["ALTText"]);
altText = HttpUtility.HtmlEncode(altText);
if (!string.IsNullOrEmpty(imageName) && System.IO.File.Exists(System.Web.HttpContext.Current.Server.MapPath("~/images/Products/" + imageName)))
{
i++;
sb.AppendLine("<tr><td>" + i.ToString() + "</td><td>" + (string.IsNullOrEmpty(altText) ? " " : altText) + "</td></tr>");
sb.AppendLine("<tr><td>" + "~/images/Products/" + imageName + "</td><td>~/images/spacer.gif</td></tr>");
}
}
dr.Close();
}
catch
{
}
if (i > 0) return true;
return false;
}
There was other code involved adding the border. No change was needed to this piece.
How to check all zip files has been extracted?
var reader: ZipFileReader = new ZipFileReader();
reader.addEventListener(ZipEvent.ZIP_DATA_UNCOMPRESS, zipDataUncompressHandler);
var zipFile: File = new File(zipFilePath);
reader.open(zipFile);
var list: Array = reader.getEntries();
zipFileCount = list.length;
trace(zipFileCount + " Numbers of items");
for each(var entry: ZipEntry in list) {
var filename: String = entry.getFilename();
if (entry.isDirectory()) {
trace("DIR --->" + filename);
} else {
trace("FILE --->" + filename + "(" + entry.getCompressRate() + ")");
reader.unzipAsync(entry);
}
zipFileWritedCount = zipFileWritedCount + 1;
}
function zipDataUncompressHandler(e: ZipEvent): void {
var entry: ZipEntry = e.entry;
var zfile: File = File.userDirectory.resolvePath('somefolder' + File.separator + entry.getFilename());
var fs: FileStream = new FileStream();
fs.open(zfile, FileMode.WRITE);
fs.writeBytes(e.data);
fs.close();
trace("Refresh Scene");
//include "RefreshScene.as";
}
My files were extracted, but I need to check all files are actually extracted.
Is there any way i can do that.
And I am using airxzip while working with zip file.
Also if I can add an loader.
You can shorten zipFileWritedCount = zipFileWritedCount + 1;
By using just a zipFileWritedCount +=1; or even
zipFileWritedCount++;
Anyways for checking the "all files extracted" amount you could try
the Equality == operator as mentioned in the manual.
Quick example :
for each(var entry: ZipEntry in list)
{
var filename: String = entry.getFilename();
if ( entry.isDirectory() ) { trace("DIR --->" + filename); }
else
{
trace("FILE --->" + filename + "(" + entry.getCompressRate() + ")");
reader.unzipAsync(entry);
}
zipFileWritedCount += 1; //add plus 1
if ( zipFileWritedCount == zipFileCount ) //if Equal to zipFileCount..
{
trace ("unzipped all files...");
trace ("zipFileCount: " + zipFileCount + " -VS- " + "zipFileWritedCount: " + zipFileWritedCount )
}
}
I am new to application block.
I am trying to get data from database. Following is the code snap.

DA:
public static List<CalendarEvent> getEvents(DateTime start, DateTime end, int user_id)
{
List<CalendarEvent> events = new List<CalendarEvent>();
SqlParameter[] sqlParam = new SqlParameter[3];
sqlParam[0] = new SqlParameter("#start", start);
sqlParam[1] = new SqlParameter("#end", end);
sqlParam[2] = new SqlParameter("#user_id", user_id);
return SqlHelper.ExecuteDataset(connectionString,CommandType.StoredProcedure, "GetData", sqlParam);
}
sqlhelper:
public static DataSet ExecuteDataset(SqlConnection connection, CommandType commandType, string commandText, params SqlParameter[] commandParameters)
{
//create a command and prepare it for execution
SqlCommand cmd = new SqlCommand();
cmd.CommandTimeout = 120;
PrepareCommand(cmd, connection, (SqlTransaction)null, commandType, commandText, commandParameters);
//create the DataAdapter & DataSet
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
//fill the DataSet using default values for DataTable names, etc.
da.Fill(ds);
// detach the SqlParameters from the command object, so they can be used again.
cmd.Parameters.Clear();
//return the dataset
return ds;
}
I am getting error:
Cannot implicitly convert type 'System.Data.DataSet' to 'System.Collections.Generic.List'.
I am unable to understand what is the problem.
In getEvents method, you need to iterate through the records in the dataset and fill in the list that you would return in this method.
var dataset = SqlHelper.ExecuteDataset(connectionString,CommandType.StoredProcedure, "GetData", sqlParam);
foreach (var row in ds.Tables["FooTable"].Rows)
{
events.Add(new CalendarEvent(...));
}
return events;
That's because you try to return a dataset as List, which it isn't.
You need to convert the dataset to a list. A possible solution would be to change the getEvents method to something like this ->
public static List<CalendarEvent> getEvents(DateTime start, DateTime end, int user_id)
{
List<CalendarEvent> events = new List<CalendarEvent>();
SqlParameter[] sqlParam = new SqlParameter[3];
sqlParam[0] = new SqlParameter("#start", start);
sqlParam[1] = new SqlParameter("#end", end);
sqlParam[2] = new SqlParameter("#user_id", user_id);
var ds = SqlHelper.ExecuteDataset(connectionString,CommandType.StoredProcedure, "GetData", sqlParam);
return ds.Tables[0].AsEnumerable().Select(datarow => new CalendarEvent{ Title = datarow.Field<string>("Title), /*the rest of your params*/}).ToList();
}
Your problem is this piece of code:
public static List<CalendarEvent> getEvents(DateTime start, DateTime end, int user_id)
{
List<CalendarEvent> events = new List<CalendarEvent>();
SqlParameter[] sqlParam = new SqlParameter[3];
sqlParam[0] = new SqlParameter("#start", start);
sqlParam[1] = new SqlParameter("#end", end);
sqlParam[2] = new SqlParameter("#user_id", user_id);
return SqlHelper.ExecuteDataset(connectionString,CommandType.StoredProcedure, "GetData", sqlParam);
}
You defined the type of this method as List<CalenderEvent> but you return a DataSet.
I do not know which datatables are contained in your dataset, but I assume there is one which represents your calenderevents.
This means you need to extract the data you want from your dataset and make a list out of it. Assuming there is one table in your dataset your new method would look something like this:
public static List<CalendarEvent> getEvents(DateTime start, DateTime end, int user_id)
{
List<CalendarEvent> events = new List<CalendarEvent>();
SqlParameter[] sqlParam = new SqlParameter[3];
sqlParam[0] = new SqlParameter("#start", start);
sqlParam[1] = new SqlParameter("#end", end);
sqlParam[2] = new SqlParameter("#user_id", user_id);
var data = SqlHelper.ExecuteDataset(connectionString,CommandType.StoredProcedure, "GetData", sqlParam);
events = ds.Tables[0].AsEnumerable().Select(r => new CalenderEvent
{
//using dummy properties because I dont know
//your class
Property1 = r.Field<string>("Column1"),
Property2 = r.Field<string>("column2"),
//...
}).ToList();
return events;
}
I believe this is a permissions issue but I don't know how to solve it, I receive the following exception:
System.IO.FileLoadException: LoadFrom(), LoadFile(), Load(byte[]) and LoadModule() have been disabled by the host.

var engine = this.CreateRazorEngine();

var results = engine.GenerateCode(new StringReader(content), typeName, "", typeName + ".cs");

using (var codeProvider = new CSharpCodeProvider()) {
var tempPath = Path.GetTempPath();
var outputFile = Path.Combine(tempPath, Guid.NewGuid().ToString("N") + ".dll");
var compilerParameter = new CompilerParameters(this.references, outputFile, true) { GenerateInMemory = true, CompilerOptions = "/optimize", TempFiles = new TempFileCollection(tempPath) };
var compilerResults = codeProvider.CompileAssemblyFromDom(compilerParameter, results.GeneratedCode);
if (compilerResults.Errors.HasErrors) {
var compileExceptionMessage = string.Join(Environment.NewLine + Environment.NewLine, compilerResults.Errors.OfType<CompilerError>().Where(ce => !ce.IsWarning).Select(e => e.FileName + ":" + Environment.NewLine + e.ErrorText).ToArray());
this.Fail(compileExceptionMessage);
return;
}
this.view = Activator.CreateInstance(compilerResults.CompiledAssembly.GetType(typeName, true, false), true) as ViewBase;
}
For clarity the CreateRazorEngine code is:
private RazorTemplateEngine CreateRazorEngine() {
var host = new RazorEngineHost(new CSharpRazorCodeLanguage()) { DefaultBaseClass = typeof(ViewBase).FullName };
foreach(var name in this.usings) { host.NamespaceImports.Add(name); }
return new RazorTemplateEngine(host);
}
Can someone let me know what code and where I need to put it to increase the level of security so that the created assembly has permission enough to load the references it has been given please.
I have implemented the Table() function in order to save the results generated by the application. However, it seems that the Timer function in the application causes the application to write over the existing CSV file each time it runs. Rather than write over the existing CSV file, I would like to append the newest search results to the existing CSV file. Is there a way to do this? Is it easier to append the results if the results are stored in a different format such as JSON?
Timer timer;
import java.util.List;
Table table;
long lastID = Long.MAX_VALUE;
void setup() {
timer = new Timer(30000);
timer.start();
goTwitter();

table.addColumn("id");
table.addColumn("latitude");
table.addColumn("longitude");
}
void draw(){
if (timer.isFinished()){
goTwitter();
timer.start();

Well, there does not seem to be a direct implementation to append to a table, so you'll have to resort to a hack: load the table in processing, write to it and resave it, sort of like this:
processing.data.Table table;
void setup() {
File f = new File(sketchPath("") + "data2/syria_16500_5.csv");
println(f.getAbsolutePath());
if (!f.exists()) {
table = new processing.data.Table();
table.addColumn("id");
table.addColumn("latitude");
table.addColumn("longitude");
}
else
table = loadTable("data2/syria_16500_5.csv", "header, csv");
TableRow newRow = table.addRow();
newRow.setString("id", "asad");
newRow.setDouble("latitude", 234);
newRow.setDouble("longitude", 2523);
saveTable(table, "data2/syria_16500_5.csv");
}
The sketch first checks if the file exists. If it does not, it creates a new table, otherwise it loads the old table in with its header.
Be warned, this is not particularly safe... If you change your columns (say, in a text editor) and try to run the sketch again you will get an exception.
