android - How to attach an image from an app to gmail -

-

Text after "div class =" itemprop = "text">

The application to take a picture and attach it to the screen and attach to the second screen, 1 button on the 2nd Gmail Photo on; Send it to someone I am using this code for the second button 

  View public void onClick (v) {// TODO Auto-generated method stub Intent intent = new Intent (Intent. ACTION_SENDTO, Uri.fromParts ("mailto", "test@gmail.com", tap)); Intent.putExtra (Intent.EXTRA_SUBJECT, "test"); Intent.putExtra (Intent.EXTRA_TEXT, "text"); Intent.putExtra (Intent.EXTRA_STREAM, imageUri); StartActivity (Intent.createChooser (meaning, "Choose an Email Client:")); }   
 But this does not attach the photo to Gmail. It may be wrong here is the rest of the code.  
  The public class increases the main activity activity {Private Static Ent TAKE_PICTURE = 1; Private Uri image Yuri; @ Override protected void saved create (bundled Instansstet) {Suprknkret (saved Instensstet); SetContentView (R.layout.activity_main); Button sendbutton = (button) findViewById (R.id.sendbutton); sendbutton.setOnClickListener (New View.OnClickListener () {@Override public void onClick (View v) {// TODO Auto-generated method stub Intent intent = new Intent (Intent.ACTION_SENDTO, Uri.fromParts ( "mailto", "test @ gmail.com ", nULL)); intent.putExtra (Intent.EXTRA_SUBJECT," test "); intent.putExtra (Intent.EXTRA_TEXT," text "); intent.putExtra (Intent.EXTRA_STREAM, imageUri); startActivity (intent CreateChooser (intent, "Choose an Email Client:"));}}); Button camera button = (button) Find VVBIID (R.D.Button_Camera); CameraButton.setOnClickListener (cameraListener); } Private OnClickListener Camera Listener = New OnListList () {Click on Public Zero (see V) {Lephoto (V); }}; Public Zero Lefoto (see V) {intent = new intent ("android.media.action.IMAGE_CAPTURE"); File photo = new file (environment .getExternalStoragePublicDirectory (environment. DIRECTORY_PICTURES), "pic.jpg"); Intent.putExtra (MediaStore.EXTRA_OUTPUT, Uri.fromFile (photo)); ImageUri = Uri.framefile (photo); StartActivityForResult (intent, TAKE_PICTURE); } @ Override Public Boolean on Krait Option Menu (menu menu) {getMenuInflater (). Flood (R. menu menu, menu); Back true; } @Override Public Zero onActivityResult (integer requestCode, integer resultCode, intent data) {super.onActivityResult (requestCode, resultCode, data); Switch (requestcode) {case 1: if (resultCode == activity. RESULT_OK) {Ure selected image = image URI; GetContentResolver () Inform (selected image, blank); ImageView imageView = (ImageView) findViewById (R.id.image_view_camera); ContentResolver cr = getContentResolver (); Bitmap bitmap; {Try bitmap = android.provider.MediaStore.Images.Media .getBitmap (cr, selected image); ImageView.setImageBitmap (bitmap); Toast.makeText (MainActivity.this, selectedImage.toString (), Toast.LENGTH_LONG) .show (); } Hold (exception e) {toast. Make Text (main activity. "This failed to load", Toast. LNNHHLANG). Show (); }}}}}}

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...
