QUESTION
If cua-mode is enabled, redefining Ctrl-Enter does not works as expected and always runs cua-set-rectangle-mark function. In the code below you can see that I also defined Alt-Enter to my function, just for testing, and it runs fine. But I wish to left Alt-Enter to cua-set-rectangle-mark because I prefer to use Ctrl-Enter to call my function that creates a line below the current line. What is wrong?

QUESTION
In a nutshell: I want two consoles for my programm. One for active user input. And the other one for pure log output. (Working code including the accepted answer is in the question's text below, under section "Edit-3". And under section "Edit-1" and section "Edit-2" are functioning workarounds.)
For this I have a main command line Python script, which is supposed to open an additional console for log output only. For this I intend to redirect the log output, which would be printed on the main script's console, to the stdin of the second console, which I start as a subprocess. (I use subprocess, because I didn't find any other way to open a second console.)
The problem is, that it seems that I'm able to send to the stdin of this second console - however, nothing gets printed on this second console.
Following is the code I used for experimenting (with Python 3.4 on PyDev under Windows 10). The function writing(input, pipe, process)
contains the part, where the generated string is copied to the as pipe
passed stdin, of the via subprocess opened console. The function writing(...) is run via the class writetest(Thread)
. (I left some code, which I commented out.)

Answered 2019-Jan-01 at 15:35The issue you're up against is the architecture of the console subsystem on Windows, the console window that you normally see is not hosted by cmd.exe but instead by conhost.exe, a child process of a conhost window can only connect to a single conhost instance meaning you're limited to a single window per process.
This then leads on to having an extra process for each console window you wish to have, then in order to look at displaying anything in that window you need to look at how stdin and stdout are normally handled, in that they are written and read from by the conhost instance, except if you turn stdin into a pipe (so you can write to the process) it no longer comes from conhost but instead from your parent process and as such conhost has no visibility of it. This means that anything written to stdin is only read by the child process so is not displayed by conhost.
As far as I know there isn't a way to share the pipe like that.
As a side effect if you make stdin a pipe then all keyboard input sent to the new console window goes nowhere, as stdin is not connected to that window.
For an output only function this means you can spawn a new process that communicates with the parent via a pipe to stdin and echos everything to stdout.
Heres an attempt:
QUESTION
So I am working on Android application. Right now I am creating MainPage where I insert Entry
which has the bottom line as always. The bottom line on my previewer is White
while on my phone it appears to be Black
.
So to fix the issue I decided to play with renderers and see if I can fix it.
I created Class in App called CustomEntryRenderer
which inherits from Entry.
Then I created Class in App.Android called CustomEntryRednererAndroid
which is supposed to change the color of bottom entry line. But it doesn`t affect it. I tried doing the same with some custom renderers I found on the internet.
For example deleting bottom line didn`t affect the program as well: removing line
Entry from MainPage.xaml:
...ANSWER
Answered 2018-Feb-18 at 19:36In xaml you are using the default Entry
control and not your CustomEntryRenderer
which is what your renderer is affecting. Also, you might want to rename it because it is not actually your renderer, but your custom control.
To resolve your issue you can either change your renderer typeof(CustomEntryRenderer)
to typeof(Entry)
to affect all Android entries in your app by default. For example, this worked for my test app for all Entries:
