c# - Using Timer to detect changes -

-

UPDATE: I added my code to show the whole process and somehow my continuity

my 3 items are listed in the pass list and there is a if statement that indicates that if my subtitle is inactive code inside a file will generate a problem Once inactive item / s is active again, how do I redo my timer? 

  Private Zero form1_load (object sender, event events e) {timer 2. Enchanted = true; } Private zero current_process () {process [] process = process. GetPrices ("ITWORKSPC152"); For (int i = 0; i    
 
 
 You do not need a timer at all. In your case, the problem is this: when you want to do something, the price list of your item changes in view. The word "event" is here.  
 Subscribe to an event in your list view, choose. I think the "AfterLabelEdit" event in that list is searching for you.  
 Here are some clues, you should customize the code in your specific context:  
  listView1.AfterLabelEdit + = (o, e) => {If (listView1.SelectedItems == faucet || listView1.selectedItems.Count == 0) Return; Var item = List view 1. Selected items [0]; If (item.SubItems = Null & amp; & amp; Item.SubItems.Count & gt; 1 & amp; amp; Item.SubItems [1] .text == "Inactive") {richTextBox1.Text = richTextBox1. Text + item.Text + "was inactive" + date time.Now To string ( "hh ':' mm tt ') +" \ n "; File.AppendAllText (@" C: \ Documents and Settings \ pamojica \ My Documents \ InactiveProgramLogs \ "+ lbl_date.Text +" .txt ", RichTextBox1 .Text);}};   
 
 Generally speaking, there is almost no easy UI handling case where the timer is required. Just use the event  
 in the "list view list point" using the timer, looks like: "I see that something changes. If not, then I will check again in a few milliseconds. I am very busy. " 
 The argument (better) with the incident is:" Hey, all of you control: when something changes ... post me! "  < / Html>

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...
