I haven't worked in WPF for a long time, but you might try setting a new list (clone the old one and add the new element) instead of adding the element to the existing list: _demo.Value++; var ne...
I am trying to combine MVVM in WPF using Microsoft.Toolkit.MVVM. Somethings are working as expected. The text boxes bind to fields and update in both directions. The button command executes and cha...
Nothing. Or anything. Or whatever you want it to mean. As a general rule of thumb: If you explicitly exit from a program with a specific exit status, then you know the meaning, or set of mean...
C++ doesn't have error codes/exit codes other than return 0; / EXIT_SUCCESS / EXIT_FAILURE. The code you are getting is from the OS when your program crashes from a run-time error. -1073740940 is ...
From section 7.21.6.2 of this draft: [T]he result of the conversion is placed in the object pointed to by the first argument following the format argument that has not already received a conve...
In addition to all the examples I gave in my answer to the linked post, all scenarios where p is a pointer to incomplete type fails. Not just the void* scenario, but also when p is a pointer to an ...
It seems to me that you are hobbling yourself by making design constraints more absolute than they need to be. For instance: You don't want to change the code under test, not even a tiny little ...
Performance-wise, I'd benchmark this vs if(memchr(src,'\0',n)==src+n) memcpy(dst, src, n); because it isn't obvious at least to me if that's faster or slower than your custom function. Regarding...
To investigate such problems, open the developer tools of your browser, and use the inspect this element feature to inspect the bounding boxes of the various elements. in Chrome: press F12 to o...
I have a code block like this: try { ... x.foo(); // This is the line that forces us to have the try block ... } catch (ArrayIndexOutOfBoundsException e) { logger.error(e.getM...
Here is an animation of a cube with faces subdivided into two rectangles, morphing into a rhombic dodecahedron, with the Platonic dodecahedron as an intermediate state. This demonstrates that the e...
I've been thinking about how the community might bring more contributors to software.codidact. One of the ways is to simply pitch codidact in questions, answers, and comments in stackoverflow. I'm ...
Note: this is mostly a personal preference that I use when moderating the posts Generally, no While "Hello" and "Thank you" are noise (overhead) for the questions and answers, they are also part ...
The question https://software.codidact.com/posts/281517 is currently voted at -3. I wrote several comments to explain why, so the author can hopefully ask better questions in the future. This morn...
tl;dr The purpose of addEventListener is to define what happens when an event is triggered at some element. But it also allows us to implement event delegation, due to the bubbling/propagation beh...
Let's say I have this class: class myService { private boolean foo(T arg) { return arg == 42; } public Response bar(U arg) { if(foo(U.field)) { return Response.st...
void (*ptr)() defines a function pointer. It says that ptr is a pointer to a function. But that function must have a void return type, and take an arbitrary number of parameters (that's what the em...
I am developing a web app that is tied to a database. My codebase is stored on a private GitLab instance. I would like to set up a workflow that would look something like this: I have a developm...
You don't need a regex for this. To find first you can simply iterate through the line until you find a digit. To find second you can do the same but in reverse. This is more efficient than running...
I am looking copy files platform-dependently on Linux, Oracle Solaris, MacOS, BSDs, and Windows. I have found some system calls for each platform, namely sendfile(), copy_file_range(), fcopyfile()...
This is usually handled by the shell, so it depends on the shell. That said, the relevant command is named the same across many different shells. Namely, the disown command. You can probably enter ...
I want to run a program, e.g. Firefox, from terminal, but whenever I close the terminal, program closes too. How to detach my terminal window from a program ran from it?
There are many ways to get the previous states of HEAD, and which one to use will depend on each situation. Git keeps reference logs (also called "reflogs"), that "record when the tips of branch...
According to Which functions in the C standard library must always be avoided?, the atoi family of functions is dangerous and should never be used for any purpose. The rationale given in the answer...
I have a PHP script that uses CURL to return a JSON result that looks //Curl set up code $result = curl_exec($ch); //Error checking code $json = json_decode($result, true); //Code to process r...
