I am attempting to enter a website, by sending an HTTP post request and getting the source code for the next page After login "Android" i'v watches too many videos but nothing works: do any of these help in this code: 

  The public class increases the main activity activity (textual text; @ Override protected zero creation (bundle saved inst Sustainate) {Super. NET (SENDED INSTEST STATES); setContentView (R.layout.activity_main); Text = (TextView) Find VViBID (RTTEV2); {New DownloadSourceCodeTask () ("Link");} hold (exception e) {GetApplicationContext (), "main in error", toast.LNNHNHLANG) Show ();}} PrivateInststream Open HTTP connection (string URL) IOException Throws {InputStream in = null; acute reaction = -1; Rl url = new url (url); url connection connection = url.openConnection (); if (! (HTTPL connection) for example new IOException ("no HTTPS connection"); Try {HttpURLConnection httpConn = (HttpURLConnection) conn; String Param = "ssousername =" + URLEncoder.encode ("Username", "UTF-8") + "Password =" + URLNcoder Encoded ("Quality of Password", "UTF-8"); HttpConn.setDoOutput (true); HttpConn.setAllowUserInteraction (wrong); HttpConn.setInstanceFollowRedirects (true); HttpConn.setRequestMethod ("Post"); HttpConn.setFixedLengthStreamingMode (. Param.getBytes ()); HttpConn.setRequestProperty ("content-type", "text / html; charset = windows-1256"); HttpConn.connect (); Response = httpConn.getResponseCode (); If (feedback == HttpURLConnection.HTTP_OK) {in = httpConn.getInputStream (); }} Hold (exception e) {log d. ("Networking", E.A.T.T.O.K.K.Lized Message ()); } Return; } Private string DownloadSourceCode (string URL) {int BUFFER_SIZE = 2000; InputStream Inn = Null; Try it in {OpenHttpConnection (url); } Grip (IOE EXPRESS E) {Log D.

This, "", "Loading, please wait ...", is true); } Zero on secure expression (string result) {if showing (dialog.is ()) {dialog.cancel (); } Text. Set text (results); }}}    
 
 
 a '& amp; Before password parameter, adding 2 lines after connect () and changing encoding in UTF-8 in content-type. Check out the new code below:  
  Try {HTPL connection connection httpConn = (HttpURLConnection) conn; String Param = "ssousername =" + URLEncoder.encode ("Username", "UTF-8") + "and password =" + URLNcoder.exode ("passwordview", "UTF-8"); HttpConn.setDoOutput (true); HttpConn.setAllowUserInteraction (wrong); HttpConn.setInstanceFollowRedirects (true); HttpConn.setRequestMethod ("Post"); HttpConn.setFixedLengthStreamingMode (. Param.getBytes ()); HttpConn.setRequestProperty ("content-type", "text / html; charset = windows-1256"); HttpConn.connect (); . Write httpConn.getOutputStream () (param.getBytes ()); HttpConn.getOutputStream () flush () .; Response = httpConn.getResponseCode (); If (feedback == HttpURLConnection.HTTP_OK) {in = httpConn.getInputStream (); }} Hold (exception e) {log d. ("Networking", E.A.T.T.O.K.K.Lized Message ()); }   
 Hope it helps.

ios - Adding an SKSpriteNode to SKScene from a child SKSpriteNode -

-
I have a SKScene where I am adding an SKSpriteNode I have subclassed the SKSpriteNode class to create this node. In the subclass I am defining some SKActions on Sprite. What do I want to do when the end of this phantom ends the SKAction sequence, then I add a new Prayer node to this scene. How is this possible. The following code is mine: The code for the sequence is that I'm running on the Scansprinitode subclass (TEMissileNode): - SKAction * moveDown = [SKAction moveToY: Self.position.y - 20 Duration: 0.2]; SKAction * animation = [SKAction animateWithTextures: textures timePerFrame: time / 7]; SKAction * moveMissileProjectile = [SKAction Moving: Pointoffscreen Term: Time]; SKAction * group = [SKAction group: @ [animation, movement projectile]]; SKAction * Sequence = [SKAction Sequence: @ [Hilldown, Group, [SKAction removalFromParent]]]; [Self run action: sequence]; From the main scene, I call those actions that execute these tasks TEMissileNode * missile = [tmissil...

Matlab transpose a table vector -

-
An embarrassing simple question seems to be, but how can I move a Matlab table vector? aTableT = aTable '; I tried a standard syntax for the simple interaction of a line vector to a line vector aTable : ATableT = reshape (aTable, 1, Height (aTable)); and aTableT = rot90 (aTable); According to the head, the last time table should work for table, see. However, I get this error code: Error type in using table / permit (line 396) Undefined function 'permute' for the input arguments. Error in rot 90 (line 29) b = magnitude (b, [2 1 3: ndims (a)]); NB: fliplr is not useful either pretty sure I have covered clear angles - any ideas? Thanks! Try changing your table into an array, move it, then back to a table In other words, try doing this: aTableArray = table2array (aTable); ATableT = array 2table (aTableArray. '); I have also read the document for rot90 , and it says that rot90 is definitely working for tables Do, and I find you...

c# - Textbox not clickable but editable -

I have a small form with 10 text boxes, I have set them in the correct tab order. I want them on my tab service I was wondering if there is a way to set the text box so that they can be selected for editing until they are tabbed. That is ... I do not want the end user to edit the text box to click on them, I just want to make them editable through tabu. this should do the trick public partial category poor text box: Text Box {Safe Override Zero WndProc (Ref: Message Message) {if (m.msg == (Int) WM.LBUTTONDOWN) {Return; // mount down events} base.WndProc (ref m); }} Window message enum can be found. How to do this without anherizing: text box : class EatMouseDown: netwindows {safe override zero WndProc (ref message message) {if (m.msg == (int) WM.LBUTTONDOWN) {return; } Base.WandProc (Ref M); }} Safe Override Zero Onload (EventEurge E) {base.OnLoad (e); How to do this without any part: left a clean part, whatever is important, this can be a buggy but it works R...
