QUESTION
I use GraphDB to store different production steps. The productionsteps are typified by their steps such as A,B,C,D. Process steps that belong together are connected by the object property ":hasUpstreamProduktionsnummer".
The data contains many different workflows. Where also a few production steps are missing. So, a Workflow can end with an instance of class B or start with an instance of Class C.
To visualize the workflow, I need to create a table that contains all production steps in one row and keeping a free space for the missing. For example:

QUESTION
I'm building an app with 3 features and a side menu to navigate through them. One of the features is a TabControl with 4 listviews displaying items (in 4 TabItems).
There are 2 main issues:
¤ First of all, when I click on "FEATURE3" it displays the TabControl but the ListViews are not rendering even though I know the items are in the ObservableCollections.
BUT If I then click on "FEATURE2" and click back on "FEATURE3", items are now appearing but only for A and not for B C D.
If I click first on "FEATURE2" and then "FEATURE3" it doesn't render at all.
¤ My second issue is that when I add items in A, it doesn't update in the listview.
Here's my current code:
MainWindow.xaml :
...ANSWER
Answered 2019-Jun-12 at 11:11For your 2nd issue, your class needs to implement INotifyPropertyChanged
so that item added to your itemsource can notify the view to be updated.
Easiest way to do this is to install Fody package https://www.nuget.org/packages/Fody/
It will inject INotifyPropertyChanged
for you.
Usage guide: https://github.com/Fody/Home/blob/master/pages/usage.md
It is pretty easy to use.
QUESTION
I have a telnet server running circlemud. I have websockify running as python proxying the connection. I can receive data as well as send data with the enclosed wstelnet.html that comes with websockify. However when I use the included simple.html file or the following code, it will receive data but will not send, or at least the telnet server never receives anything.
I am assuming the data I am receiving is blob, because that is the only way I can parse it. When you output the raw data to console it doesn't specify what data type it is. Also I am using the default Websocket api with my only include being jquery.
In the following I receive the message $('#message').html("asking for username"); as intended but the ws.send(blob); never sends anything, I have also tried just regular ws.send("test123"); to no avail.
...ANSWER
Answered 2019-Mar-11 at 19:19Make sure your client is sending line endings (i.e. ASCII character 10 or '\n') that the telnet server is expecting because it won't do anything with the text you sent until it sees a whole line.
QUESTION
I am trying to create a method called 'tilt' in a Python class which turns the DataFrame upside down using Pandas. But I am getting this error "The object has no attribute 'iloc'", whenever I use this 'tilt' method on an instance created out of this class.
...ANSWER
Answered 2019-Feb-09 at 18:34In .tilt()
, you use self.iloc[::-1]
. However, inside the scope of this instance method, self
is just a plain, minimalistic Python class, not a DataFrame. It knows nothing about the operations that you did to the local variable self
inside of .arrange()
.
Even if you call b.arrange()
first, this does not modify the class instance inplace; it modifies a local copy of a variable called self
inside the scope of .arrange()
. That is:
