I'm using Android Navigation Component for Navigation. I have a LoginFragment which has a button to transition to SignUpFragment. On clicking the button I'm getting this error.

I am making a program with a start and help menu, as well as other functions. The buttons on the "main menu" work perfectly, but once I enter the Help menu, the buttons I have programmed for screen navigation do not work properly. Please feel free to look at the code below. I keep getting an error that says "BackHelpRect not defined". BackHelpRect is a rectangle I have drawn around my image buttons (as for all the rest of my buttons) to sense for when the mouse is touching them. It works for the main menu buttons but once I go into the help menu, the rectangles for those buttons "disappear". If you have a solution, please respond, it would be greatly appreciated. :)

Sorry I have attached my entire code, but everything is called within other functions and it all works in sync with each other. Sorry if it is very long.

i wanted to group by an array of object with multiple field and i have done it and i wanted to concat the email first with respect to the reportName and then with respect to the particular events i have done that part but when i am doing that in the fields i get it undefined with them i want to remove that undefined and print only the strings of email.

I'm creating an application which listens on a port, and when a client makes a request, it spawns a new process with a different user using LogonUser,CreateProcessAsUser .

I've setup 2 events with CreateEvent() function to signal the child that WSADuplicateSocket is ready to pass the SOCKADD_STORAGEW structure to the child process via a memory mapped file.

The OpenEvent() in the child process keep failing with error 5 (access denied ) when it is spawned from the application.

If I manually run a child/client using (shift + right click, run as) the OpenEvent function successfully manages to open the event.

The event is created in the global namespace (Global\myevent) and for testing purposes I have created a null Dacl ( i have verified permission on the Event with winobj )passed to the the CreateEvent() function.

I don't see what I'm missing .

here the concerned code snippet:

I have a sidemenu in HTML like this:

I am reading about implementation of state machines using variants. I try to create a construction that take a variant parameter to initialize the state. However whent the constructor is defined , I get a warning that this is recognized as function declaration.

Moreover when I try to define a setter for the state, compiler error is generated when try to call this

Here is the code

I am trying to split a List into two Lists using LINQ without iterating the 'master' list twice. One List should contain the elements for which the LINQ condition is true, and the other should contain all the other elements. Is this at all possible?

Right now I just use two LINQ queries, thus iterating the (huge) master List twice.

Here's the (pseudo) code I am using right now:

I am trying to fin elements that have title attribute whose value matches a case insensitive string that I supply. ie. matches regardless of whether they're the same case.

When I try the following it works:

I have 2 programs. The first program will open the second one and will also create 2 Event objects that will be used for synchronization. The second one (the one to be opened) will open those 2 Event objects. Both of the programs will run a for loop to simulate writing and reading operations from memory.

Program one:
