android - wait to asynctask finish from another asynctask -

-

im is querying a DB with an asyntask that works in an object, and this object is a The problem is that I do not know the way to wait for query results before trying to use methods from this object. This taps point is the reason for exception. I tried with this time and it works, but I know it has not been done properly. 

  // With this constructor I create an asyntask which db empresa = new Empresa (id_empresa); / * While (! Empresa.consulta_terminada) {// none of the advice on this question) * / Log.e ("EMPRESA NOMBRE", empresa.getNombre ()); Sita = new Sita (Itenario, Hora_Farmato, Empressia); Citas.add (cita);

Sorry for my english and thanks!

Pass a runnab for AsyncTask, and open it on postExecute (). Or use handler and handler thanks to doing async tasks, this will be more flex.

c# - Highlight all words containing a letter in a richtextbox -

-
How do I highlight all the words in a letter in a rich text box? If I want to expose the words that contain the letters "a", such as a hat or candle word, both words are highlighted, I am using C # on Winform. Private Zero Button 208_Click (Object Sender, EventArgs E) {HighlightFrage (Rich Textbox 1, "A", Color. Yellow); } It exposes all the words with a word "a", but I'm not sure how to highlight the length of the spaces. Thank you. You can use the method to find incidents of sub-location. Then, use the property to change the colors back to Highlight colors for each event. int len ​​= richTextBox.TextLength; Int index = 0; String textconfind = "A"; // This will highlight the text you are viewing (index & lt; len) {richTextBox.Find (textToFind, index, len, RichTextBoxFinds.None); RichTextBox.SelectionBackColor = Color.Yellow; Index = rich textbox. Lesson Index (texttofind, index) + textaophind Langeline; } If you want...
