how to check is image inserted to database in android -


I have a table in the database that has several rows and each row stores an image and some string

But there is no image in some line

I want to read the contents of this table in my Android app and if I do not present the image I show a default image

How can I check that image? Does present or not?

This is my code 

  private zeros sql_load_data () {byte] sick_pic = null; Cursor cur_row; SQLiteDatabase sqLiteDatabase = SQLiteDatabase.openDatabase (DatabasesHealer.DB_PATH + "/" + DatabaseHelper.dbidi, blank, contextMODE_PRIVATE); Try {DBH.openDataBase (); Cur_row = sqLiteDatabase.rawquery ("disease_name, disease_fick, disease, disease_reaction, disease_select from control pistilians where id =" + id, blank); Cur_row.moveToFirst (); Lbl_illness_name.setText (cur_row.getString (0)); Illness_pic = cur_row.getBlob (1); Imgviw_illence_pic.setImageBitmap (bitmapfile.ededabiterror (illness_peak, 0, disease_pk.lamp)); Lbl_illness_cause.setText (cur_row.getString (2)); Lbl_illness_sign.setText (cur_row.getString (3)); Lbl_illness_control.setText (cur_row.getString (4)); } Hold (exception e) {e.printStackTrace (); }}

if nothing is left then if (illness_pic == Blank) should be enough to check.

The other possibility is to add a field HAS_IMAGE and use it to check it. Set it to 1 when you do not delete the image and by saving or deleting 0 .

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ
