 Any help please   
 
 
 Inspecting your HTML Exception is actually an iTextSharp exception, but instead comes from iTextSharp. Net Framework is asking to download a remote resource via the  System.Net.WebRequest . In a way or another, you have got the URL that is  http  or  https  (or  file  or  ftp ), often This is a base 64 encoded image. You can reproduce this message by doing this:  
  var req = System.Net.WebRequest.Create ("data: image / png; base64"); Req.GetResponse ();   
 
 A first instance of type 'System.NotSupportedException' occurred in system.dll exception  
 type 'System.NotSupportedException' of an unspecified exception system Additional information: URI prefix is ​​not recognized   
 If you had a protocol short / protocol relative URL you would receive a slightly different message.   / P> 
  var req = System.Net.WebRequest.Create ("// gerp"); Req.GetResponse ();   
 
 A first instance of System.Net.WebException exception system.dll  
 occurred in the exception of an unspecified type of 'System.Net .WebException 'happened in System.dll'  
 Additional information: The form of UNC path should be \ server \ share.   
 You have to change the HTML only to use a support protocol or potentially.

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...

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.
