I'm building an app that should- among other things, let the user capture a picture and then save the picture and other info (like location of where this picture was taken -using GPS of the phone and etc...) on a DataBase.
Im using a string to save the pictures to the DataBase. So far so good. My problem is that after the user has captured a picture I can not find the path of the picture anyWhere (in order to display it later to the user ) I know I can display the picture if I use a image and not a string but then I am not able to save it to the DB.
Also I used the picture string (which should be the path of the picture ) to be the primaryKey column in my table and if the string is null this will be a problem for sure.
After checking on the internet I found out that you cannot use the GeoCoordinateWatcher (for GPS) on the emulator so I had to use a random place. This led me into thinking that a picture taken by the emulator may not have a path??
Part of my code: (the Event of the camera and the bottun that saves everyting to DB)
void c_Completed(object sender, PhotoResult e)
{
if (e.TaskResult == TaskResult.OK)
{
MessageBox.Show(e.ChosenPhoto.Length.ToString());
//Code to display the photo on the page in an image control named myImage.
BitmapImage bmp = new System.Windows.Media.Imaging.BitmapImage();
bmp.SetSource(e.ChosenPhoto);
myImage.Source = bmp;//display the picture right after taking it. before saving to DB
p.UrlImage = bmp.UriSource.AbsolutePath;//Do not Work!
}
}
private void saveToDB_Click(object sender, RoutedEventArgs e)
{
p.Description = DesriptionList.SelectedValue.ToString();//description of the pic
p.Date = DateTime.Today;//date picture taken
GeoCoordinateWatcher myWatcher = new GeoCoordinateWatcher();
var myPosition = myWatcher.Position;
p.Location = myPosition.Location.Altitude+" "+myPosition.Location.Latitude;//do not work with emulator
p.Location = "Some Where Over The Rainbow";
MainPage.m._bl.addPic(p);//add pic to DB
MessageBox.Show("Added Successfully! :)");
NavigationService.Navigate(new Uri(@"/Intro.xaml", UriKind.Relative));//go to another page
}
}
my class:
[Table]
public class Picture
{
public Picture()
{
}
public Picture(string l, string d, string url, DateTime da)
{
Location = l;
Description = d;
UrlImage = url;
Date = da;
}
string location;
[Column]
public string Location
{
get { return location; }
set { location = value; }
}
string urlImage;
[Column (IsPrimaryKey=true)]
public string UrlImage
{
get { return urlImage; }
set { urlImage = value; }
}
DateTime date;
[Column]
public DateTime Date
{
get { return date; }
set { date = value; }
}
string description;
[Column]
public string Description
{
get { return description; }
set { description = value; }
}
}
}
Anyway- I would like to know if I can get the path in some way... And also- if I cant get the path- does Windows have a "Better" emulator? this emulator cant do much and this is quite annoying giving the fact I dont have a WP to check my apps on.. Thanks!
