QUESTION
I am learning C programming from "Learn c the hard way by Zed Shaw". He asks the learner to try and break their own code.
So I tried the following C code and thought printing more values that I gave argv will break it but it did not until later.
...ANSWER
Answered 2021-May-30 at 09:48A segmentation fault happens when the code try to access a memory region that is not available.
Accessing an array out of bounds doesn't means that the memory before or after the area occupied by the array is not available: The compiler or the runtime usually put all varibales or data in general in a given block of memory. If your array is the last item of such a memory block, the accessing it with a to big index will produce a Segmentaion Fault but is the array is in the middle of the memory block, you will just access memory used for other data, giving unexpected result and undefined behavior.
If the array (In may example, but valid for anything) is written, accessing available memory will not produce a segmentation fault but will overwrite something else. It may produce unexpected results or crash or segmentation fault later! This kind of bug is frequently very difficult to find because the unexpected result/behavior looks completely independent of the root cause.
QUESTION
I want to refresh the aero preview that's displayed when hovering over a taskbar icon on Windows (or when Alt+Tabbing).
I found a function called DwmInvalidateIconicBitmaps
that seems promising, but when I use it:
ANSWER
Answered 2021-May-06 at 17:41The documentation clearly stipulates this:
hwnd
A handle to the window or tab whose bitmaps are being invalidated through this call. This window must belong to the calling process.
If this is not the case, you'll get an E_INVALIDARG
error.
QUESTION
How do i remove or filter this kind of message?
This is very annoying and keeps displaying the whole time I cant understand why. Im using visual studio 2019 c++.
After reading this line of code:
MessageBox(g_hWnd, string.data(), L"", MB_OK | MB_ICONSTOP | MB_SETFOREGROUND | MB_APPLMODAL | MB_TOPMOST);
The message always is displayed:
...ANSWER
Answered 2021-Feb-16 at 09:28This is an example of an XY Problem, also discussed here. Instead of trying to prevent the messages from being shown, it would be better to prevent them from being generated in the first place.
Judging by the links you posted, this problem has existed for a few years and has bothered many people. Fortunately your first link appears to have a workaround: the post by user "codeviewer" lists a function called suppress_dwmapi_output()
which when added to your code and called from InitInstance()
will apparently prevent these messages from being created.
Disclaimer: I haven't tried this myself.

...ANSWER
Answered 2021-Feb-15 at 14:33Looks like you are missing libssl-dev
. Just open your terminal and run the command sudo apt install libssl-dev
. You might have missed the buildozer dependencies. So even after installing libssl-dev
you get error then try running the following command:
QUESTION
I'm trying to build an apk out of a simple kivy python file however I get this error when using the command "buildozer -v android debug" to build the apk.
I'm running on a Ubuntu virtual machine, java jdk is version 8 something, I was using version 14 earlier, but saw some post talking about needing version 8. Not entirely sure though if it was for the same problem that I'm facing.

Answered 2021-Feb-13 at 11:05You were missing libffi-dev
earlier and now you are missing libssl-dev

Solution-
Add following env variables to the container
export PYSPARK_PYTHON=/usr/bin/python3.9
export PYSPARK_DRIVER_PYTHON=/usr/bin/python3.9
Trying to create a spark container and spark-submit
a pyspark script.
I am able to create the container but running the pyspark script throws the following error:
Exception in thread "main" java.io.IOException: Cannot run program "python": error=2, No such file or directory

- Any idea why this error is occurring ?
- Do i need to install python separately or does it comes bundled with spark download ?

QUESTION
I was using i3. Now I want to see dwm. Made keybidings to run firefox on Modkey+w
. It works well, but now when I want to do similar commands for nvim, ranger, cmus (all terminal programs) it isn't working. Can't run them from dmenu also. Is it ok, or I just fiddled with my config files?
ANSWER
Answered 2021-Jan-12 at 18:29Nvim and Ranger run in the terminal, so just running the binaries won't do anything. You'll need to run them in your terminal. How that works depends on your terminal, but it is likely something like your-terminal -e ranger
, or static const char *ranger[] = {"xterm", "-e", "/usr/bin/ranger", NULL };
for example.
QUESTION
Can anyone please resolve my issue I am using buildozer on a linux virtual machine to convert a .py file to apk for my android mobile
This is my first kivy project and i really need some help to make it possible
This is the code
...ANSWER
Answered 2020-Dec-18 at 12:12I guess you have your files in a directory named 'Lunar Aplocon'
. The space ' '
in the file name is causing the issue. Even when you enter the name in your buildozer.sec file try not to include any space (you can include in title but not in org and other info). So you just have to rename your directory then it will be just fine.
QUESTION
I made a simple python app using kivy and when I wanted to convert it to apk using buildozer it kept giving me this error. I searched everywhere but couldn't find any solution. Do you guys have any idea ? (stackoverflow is asking me to provide more details so don't mind this line. Below is the output I get when running the buildozer -v android debug command.)

Answered 2020-Dec-13 at 17:52ValueError: storage dir path cannot contain spaces, please specify a path with --storage-dir
As it says, try using a directory without spaces in its name.

so i wanted to create a list of categories (Day-Week-Month) and i achieved it just fine using a
listView.builder but it isn't centered on the horizontal axis so i had the idea to do it with containers.
