QUESTION
I am dealing with this error for 2 days. Searched for lots of questions but none of them solved my problem When I click on a dynamic view that has onClick this error shows up:
java.lang.IllegalStateException: Could not find method Save(View) in a parent or ancestor Context for android:onClick attribute defined on view class android.widget.Button with id 'save'
Even if inside the method is blank.
This is an news app and when I click add button an edit view shows up and I write the news and then I click the save button, then news is displaying on the main screen. But as I said when I tap on the save button it crashes. I is totally about onClick but I am expecting your ideas :)

I am trying to create a discord bot for my server with Python and I am trying to set my token, special variables, etc. So I set my variable in the .env file and called it. The message worked but it has a "Mojibake" problem that looks like this:
...ANSWER
Answered 2020-Sep-03 at 05:37Your problem arises due to different encodings when saving and reading the file. Generally if applicable, you should aim to always encode text files with UTF-8. This requires you to use a text editor that allows specifying the encoding the file should be saved with. Most code editors and IDEs do allow this. Even with Window Notepad you can explicitly specify the Encoding in the File
> Save as...
dialog.
Alternatively, you can enter your non-ASCII characters in the string with a Unicode escape sequence \uxxxx
where xxxx
is the hexadecimal value of the character's unicode code point (e. g. \u015f
for ş
). You'd need to individually look up the code point per character, either just with google or tools like the windows character map.

QUESTION
I want to disable some items of combobox by specific conditions. For this issue, I used multibinding. If I described all items of combobox in xaml, there is no problem. But I want to populate combobox items programmatically. So in this case , I could not get items, returns null, and throw me out of the program in the first step. my xaml codes are like that:
...ANSWER
Answered 2020-Jun-08 at 17:13It would be interesting to know what exact error you get.
I assume the ComboBoxItem.Content
returns null
. The item containers are rendered (generated) after the ComboBox
is opened. Only the data items exist at this moment. So opening the drop down the first time all item containers are null
and about to be rendered.
Anyway, the following simplified version of your code will very likely fix your problem:
TekerDisabler.cs
QUESTION
The short and immediate version of the question is: Why are these two regex different? i.e.,
href=(['"]).+?\1
vs
href=(['"]).+?['"]
or href=(['"]).+?(['"])
I am practicing regex on this site and I am trying to solve this level

I am posting the entire content here in case the site goes down in future.
...ANSWER
Answered 2020-Jun-06 at 23:34The backreference has to match the same thing that the capture group matched. So the first regexp will match
QUESTION
I am trying to do a simple windows app for picking a random movie from my trakt.tv watchlist, I used tkinter for a basic gui, then use random funciton to choice a movie from a txt file, then with trakt library fucntion I get my watch list from trakt and record it as a txt for random choice, define a function to one of my button to pick a random movie from there and show it in text box. It's working in that way but now I want to add overview, rating, year information related to the random movie, it is working good for just "some titles" but some movies get following error message; "trakt.errors.NotFoundException: Not Found - method exists, but no record found"
I think some movie's names can't get direct result from trakt.tv, so what could be solution for that? For example; can I get trakt_id from a watchlist and use it for all other information and how? I check library files but it seems get the info directly user list website and I couldn't figure out how can I get any other information from there. Also how can I add a random fanart under the buttons related to movie which choiced by random?
Sorry my English and if I can't explain my questions well :)

Answered 2020-Feb-17 at 18:16For adding an image you need to create an instance of PhotoImage
with the file path to your picture. Then when you want to map the picture you have several options of widgets which could contain images but I'd recommend using Label in this case. So create an instance of Label
with the keywords you like and set image=
. Make sure you don't just have the PhotoImage instance on a temporary variable. So i.e. when you are doing all this inside a class you can make the PhotoImage variable a class variable. Otherwise, you can make it a sub variable of your Label widget. In the end, it is your own choice. For your images you're then limited to .png, .pkg, .gif (not moving as far as I know) and a bit more (look that up at effbot.org). You can also use .bmp but then you will need to use BitmapImage
instead of PhotoImage
. A little Example:

I have a dynamic tree structure. I can add 3 elements to this tree structure called " Montaj, Kaynak, Parça and Sarf ".
My Problem: After adding the Parça And Sarf, nothing can be added under them. For example, everything can be added under Montaj and Kaynak , but once you add Parça or Sarf, nothing can be added under them.
How can I do it? ( Some terms are in Turkish. Don't mind ) My current code is the following

Answered 2019-Jul-18 at 10:25If you want to block people from creating any new nodes under the Parça
and Sarf
items, then only show the EKLE
menu options when the user right-clicks on the nodes that you want them to be added to.
Firstly, you need to be able to distinguish between folder items and normal ones, which means you need to define your types

QUESTION
I am working on I/O classes in Java. I understand that there are two important type of streams: byte stream and character stream. But... I have tried to read and write text file with byte stream and it worked. Here is the code:
...ANSWER
Answered 2017-Oct-22 at 14:38java.io.FileInputStream
javadoc states :
FileInputStream is meant for reading streams of raw bytes such as image data. For reading streams of characters, consider using FileReader.
java.io.FileOutputStream
javadoc states something similar enough :
FileOutputStream is meant for writing streams of raw bytes such as image data. For writing streams of characters, consider using FileWriter.
One of main differences between FileInputStream/FileOutputStream
and FileReader/FileWriter
is that the first provides methods to manipulate bytes while the latter provides methods to manipulate characters.
In your example, as you copy a file content into another file, manipulating char
or byte
doesn't make a big difference.
In your case, a FileInputStream
or a BufferedInputStream
seems even more appropriate.
But if you use a stream to read/write characters from/into String
instances,
using FileReader/FileWriter
eases really the things and make things clearer.
Besides, you could also wrap FileReader/FileWriter
into a BufferedReader/BufferedWriter
and benefit from efficient reading/writting of characters, arrays, and lines.
