c# - Blend Interaction Behaviour gives "points to immutable instance" error -

-

I have a UserControl that is the base class for other user controls, which are displayed in "Model View".
I have been shown that all user controls are fading while closing. I also want the user to be able to move around control. My constructor looks like this: 

  var tg = new TransformGroup (); Tg.Children.Add (new scale transforms ()); RenderTransform = TG; Var behavior = interaction. Gatebehaviers (this); Behaviors.Add (New TranslationZembraneBewire ()); Loaded + = modal_log_logged_loaded;

and the ModalDialogBase_Loaded method looks like this: 

  Private Zero ModalDialogBase_Loaded (Object Sender, RoutedEventArgs E) {var fadeInStoryboard = (Storyboard) TryFindResource ("modalDialogFadeIn "); FadeInStoryboard.Begin (this); }

This method is called when I press the close-button on the control: 

  Close the protected virtual zeros () {var fadeOutStoryboard = (Storyboard) TryFindResource ("modalDialogFadeOut"); FadeOutStoryboard = fadeOutStoryboard.Clone (); FadeOutStoryboard.Completed + = Delegate {RaiseEvent (New Routing Avenger); }; FadeOutStoryboard.Begin (this); }

The storyboard that looks like this: 

  & lt; Storyboard x: key = "modalDialogFadeOut" & gt; & Lt; DoubleAnimationUsingKeyFrames Storyboard.TargetProperty = "(UIElement.RenderTransform) [TransformGroup.Children] [0] (ScaleTransform.ScaleX) .." Storyboard.TargetName = "{x: Null}" & gt; & Lt; EasingDoubleKeyFrame Keytime = "0" value = "1" & gt; & Lt; EasingDoubleKeyFrame.EasingFunction & gt; & Lt; Backgie's Azingsmode = "is in in" expounded = "0.3" /> & Lt; /EasingDoubleKeyFrame.EasingFunction> & Lt; / EasingDoubleKeyFrame & gt; & Lt; Time of EasingDoubleKeyFrame = "0: 0: 0.4" value = "0" & ​​gt; & Lt; EasingDoubleKeyFrame.EasingFunction & gt; & Lt; Backgie's Azingsmode = "is in in" expounded = "0.3" /> & Lt; /EasingDoubleKeyFrame.EasingFunction> & Lt; / EasingDoubleKeyFrame & gt; & Lt; / DoubleAnimationUsingKeyFrames & gt; & Lt; DoubleAnimationUsingKeyFrames Storyboard.TargetProperty = "(UIElement.RenderTransform) [TransformGroup.Children] [0] (ScaleTransform.ScaleY) .." Storyboard.TargetName = "{x: Null}" & gt; & Lt; EasingDoubleKeyFrame Keytime = "0" value = "1" & gt; & Lt; EasingDoubleKeyFrame.EasingFunction & gt; & Lt; Backgie's Azingsmode = "is in in" expounded = "0.3" /> & Lt; /EasingDoubleKeyFrame.EasingFunction> & Lt; / EasingDoubleKeyFrame & gt; & Lt; Time of EasingDoubleKeyFrame = "0: 0: 0.4" value = "0" & ​​gt; & Lt; EasingDoubleKeyFrame.EasingFunction & gt; & Lt; Backgie's Azingsmode = "is in in" expounded = "0.3" /> & Lt; /EasingDoubleKeyFrame.EasingFunction> & Lt; / EasingDoubleKeyFrame & gt; & Lt; / DoubleAnimationUsingKeyFrames & gt; & Lt; Double animation tool keyframe storyboard Targetproperty = "(UIElement.Opacity)" storyboard. Target = "{x: tap}" & gt; & Lt; Time of EasingDoubleKeyFrame = "0" value = "1" /> & Lt; EasingDoubleKeyFrame keytime = "0: 0: 0.3" value = "0" /> & Lt; EasingDoubleKeyFrame keytime = "0: 0: 0.4" value = "0" /> & Lt; / DoubleAnimationUsingKeyFrames & gt; & Lt; / Storyboard & gt;

If user controls are shown, and users do not move it around the screen, then everything works fine. However, the user moves around to control, so I get the following error when the modalDialogFadeOut Storyboard is started:

In the 'child' way of property '(0) (1) [0]. . (2) '' system. Windows Media. Transform Collection 'indicates an irreversible example.

How can I fix this?

The issue that is changing to TranslateZoomRotateBehavior is its ScaleTransform with a MatrixTransform, a property no longer exists Due to the first two animations in your storyboard to target

Since you can not animate the value of a matrix to get the effect of fadeout, I would use an extra container for control behavior, and then one visually exiting one.

windows - Heroku throws SQLITE3 Read only exception -

After I deploy the app to Heroku, I have to run migration scripts and get this error message ... ITES \ padrino \ prophetmargin & gt; Heroku Rack AR: Rack mutated! SQLite3 :: ReadOnlyException: only one try to write database to read: CREATE TABLE "schema_migrations" ( "version" varchar (255) NOT NULL) /disk1/home/slugs/215264_925fd2c_65a3/mnt/.bundle/gems/gems/ padrino-core- is 0.9.11 / lib / padrino-core / cli / rake.rb: 9: in `init ' how can this be? I also tried to run Heroku dbpush SQLite: //db/my-db.db and that did not work Horoku sqlite3 but using postgres does not do. I'm not sure why you are receiving this error, however, as I have used sqlite3 in development and when pushing it into its travel, they do some magic which migrates to postgrads. I'm absolutely sure how Heroku does 'backwash' this database but it seems that this is happening to you because it's the SQLite db file which is obviously due to Heroku's

lex - Building a lexical Analyzer in Java -

I am currently learning lexical analysis in compiler design. To know how a lexical analyzer actually works, I am trying to build myself. I am planning to make it in Java The input to the lexical analyzer is a .tex file that is of the following format. \ section {script} {intro} \ section {Scope} arbitrary text \ section {relevance} uncontrolled text \ subdivision (profit) arbitrary text \ subsubsection {in real life} \ subdivision {Ingredient} \ end {document} The output of the lecture may be a table of contents with a page number in another file. 1 Introduction 1 1.1 Scope 1 1.2 Relevance 2 1.2.1 Benefits 2 1.2.1.1 Real life 2 1.2.2 loss 3 I hope that This problem is within the scope of Language Analysis Read the .exe file and check '\' and continue to check whether it is actually on search In the sectioning command is set to indicate whether or not a flag variable is the type of sectioning. I hope the above approach will work for the construction of Lexa

python - rename keys in a dictionary -

-
I want to change the names of keys in a dictionary which are ints, and I need them so that the inputs with key zero They can sort correctly. For example, my keys are like this: '1', '101', '11' and I may need them: '001', '101', '011' What is doing, but I know that there is a better way tmpDict = {} in the ADC for the old: t MpDict ['% 04d'% int (olden)] = addict [oldkey] New controlled = tmpDict You are going wrong about this if you want to draw entries on a line in a specific way, then you have to sort on the extraction. for sorted (D, key = int): print '% s:% R'% (k, d [k]) < / Div>
