uri - WPF MediaElement Natural Duration -

-

I have a media element that I set my source in a new URI based on a valid string.

For example:

MediaElementName.Source = new URI ("string");

The string is a valid path, and after debugging, sometimes it sets the NaturalDuration of "MediaElementName"

I now at least with the result of any work Googling for 2 hours has gone ..

Anyone here has an idea why sometimes it will set naturalness, and sometimes it does not happen? I am able to play Wave, but do not know how long wav file (time duration)

Any help or thought is appreciated, thanks!

I know that it is very late but then Also my experience is in two forms of this problem.

a) The codec (flac can be an example of this) can not know the duration. Check and see if the windows media player is showing the progress bar (I had this problem in some flax files being created by custom frame) I suspect there was no "index" inside the file. Apart from this, the Flax format gives different results based on different results, if it is running on a local file or at http (I suspect why this is because because when he can not search within a stream, he Length can not be found).

b) Some codec do not provide some content until they provide some content, to solve it, I have a timer running that uses Player.NaturalDuration.HasTimeSpan and then Get the TimeSpan. It usually starts playing within a few seconds of the media within a few seconds. Investigating timepoints in Player_MediaOpened does not work reliably.

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>
