PHP Regex to allow special characters but no any space -

-

I have the following regs so that alphanumeric characters and the following special characters are allowed 

  / () -   
 is a regular expression  
  / [^ a-za-z0-9 - () - /] /   
 complete method  
  public function valid number ($ number) {$ return = true; $ Matches = null; If ((preg_match ('/ [^ a-za-z0-9 - / () -] /', $ number, $ match) gt; 0) {$ return = false; } Return $ return; }   
 The above method woks are fine, but if the number is replaced then TRUE also comes back. When I remove '/' from regx, then if the number is 'space' then it gets wrong.  
 It seems that there is some problem in 'Regex'.  
 Please give some advice to allow the letters of letters and the special characters above. Regex  / () - << / p>  
 
,  
  ^ [A-Za-z0- 9 () \ / -] + $   
  ^  Inside (on top) Chocker class does not make sense. So your Részek character does not give any letters of the people described in the class. Even better to avoid  /  inside the character class and always consider entering  -  at the beginning or end of the character class. To allow more letters of one ore described in four classes, you must add  +  after the character range.  
  Explanation:   The beginning of the string [A-Za-z0-9 () \ / -] + Any character: 'A' to 'Z', '$ 9', '(', '' ''), '' / 'before', and 'before' an optional \ n before 'a' and 'j', '0' before the string

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. 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...
