ColorHelper | Sublime plugin that provides helpful color previews | Code Editor library

I am following Colt Steele's React course. Sadly, the course is outdated so I chose to migrate to the latest versions of libraries myself.

Coming to the point, I am now facing this error where I am not able to extract URL params using the useParams hook in my functional component. I am pasting my code below for the community to check.

im very new to storyboards and animations.

While their setup concept is fairly straightforward, i've been struggling trying to find an efficient way to destroy them to preserve memory in my specific scenario.

Basically i have a listview with several items (list view is dinamically populated by a database) when clicking a button i would like for the listview item to perform a color animation to a specific argb color, since the number of items is dinamically populated, it can have tens or hundreds of items.

To make this process more efficient memory wise and cpu wise, i would like to create animations on the fly, rather than have unnecessary animations per each item, everything works fine except i feel like i need to dispose them to release unnecessary cpu and memory usage which i have no idea on how to do.

Below you can find the code for the button click event which performs the entire operation

employees_data_model.selected_employee_contact.DeleteEmployee = employees_data_model.selected_employee_contact.DeleteEmployee == false; var _Container = Employees_List_View.ContainerFromItem(Employees_List_View.SelectedItem); var GridItem = FindMyChildByName(_Container, "GridItem") as Grid;

I have a C# solution with 3 C# .Net framework 4.7.2 projects of which a simple Class Library, a Windows Forms Control library and a Windows Forms test application. I've created a control which calls a static function in a public class "ColorHelper" for retrieving a secondary blended color based on the fore color of the control. This works fine in both designer and runtime, when this function is in the same project as the control, but throws this exception when placed in the third project, i.e. the Class Library. I've referenced this 3r project and also included the using statement. Syntax seems Ok, no errors on compiling, however when I want to place the control on a test form, the exception is thrown.

I have a list:

I'm trying to declare functions in my ~/.jq so they can be re-used. I am not sure I've got the correct syntax for passing parameters. I've looked at the builtin.jq source but the recursion flew over my head. Can anyone help clarify if the way I've done it below is correct?

N.B. I know it's more efficient to run jq instead of the "useless use of cat", but for clarity I've written it that way so all the jq syntax is on the RHS.

I have two BLOCS.

I'm trying to figure out how to solve a color boxes exercise that applies useState hook concept. Given an array that contains 12 different unique colors, initially the state will show 12 divs with a corresponding color. Upon clicking the button, only randomly chosen div will change to a random color(out of the 12 given colors) as well as flagging that div with the message "changed" on the div. So far I was able to make the color box container showing each color on a div. I see the state is changing to a random color every time when I click. But I don't know how to make only that random div to change the color and show the message. Does this problem require a unique id for each color for tracking change of the state?

My NowPlayFullPage has a PlaylistControl, which is basically a ListView.

In a C++/CX class I want to create a DependencyProperty that gets or sets a normal C++ float value type but I just cannot figure out how I need to specify the type that is expected by the DependencyProperty::Register.
