I am a Visual Studio MFC newbie, and have been a bit perplexed by a problem over the last couple of days. When I create a radio button and assign it variable, I get a "Debug Assertion Failed". How should I make the radio button a variable?
You have to make sure that the first radio button in a sequence of radio buttons is of style WS_GROUP. It is a style you can set in the dialog editor by selecting the first radio button and setting its style to Group.
You want to use an int as the type to receive/set and only use DDX_Radio() on the first radio button on the group. It will return 0 if first radio selected, 1 if second, 2 if third, etc... Make sure the value you use, a member variable is initially set to 0 or another valid value.

I have a bootstrap table and a form (inline-formset-factory) associated with each row in that table. That form should appear and disappear below the corresponding row when a button is clicked in that row.
i tried Bootstrap collapse option but while clicking the button(form submit) in the row to induce the inline formset factory form with specified parent model, the form opens in all the rows. But i wanted the from to appear in that corresponding row only.

How do I remove this icon?
I am using very simple code; just navigation view
As mentioned in the comments by #Nirav D, this button is used to toggle the sidebar visibility.
iOS 16 & above
In iOS 16, Apple gave Navigation a big refresh:
Introducing NavigationStack(which is probably what you want), it is used to present a view allowing the user to navigate using NavigationLink as you would on an iPhone.
Introducing NavigationSplitView(which is what you’re seing in the simulator right now), it is used to present a menu (sidebar) that can present detail views. You can have up to 3 columns.
Deprecating NavigationView, from now on you have to use the above containers as NavigationView will be obsoleted in a future iOS release.
iOS 15 & below
In versions earlier than 16, you have to use NavigationView. NavigationView accepts navigationViewStyle, the default style on iPhone is StackNavigationViewStyle where the content is presented in one column. However, on iPad in order to maximise the use of screen estate, SwiftUI sets the default style to ColumnNavigationViewStyle that presents the content in columns (Master -> Detail…).
If you mean to use a single column: you must use either NavigationStack or NaigationView with .navigationViewStyle(.stack);
If you have to use multiple columns & still hide the button: use .navigationBarHidden(true) on the sidebar view, or .toolbar(.hidden, for: .navigationBar) for iOS 16+.

I have link on ID column, when user click on link there is an EDIT button.
When click on EDIT user can make changes.
But, I want to ensure that two users can't edit in same time, and when one user click on edit that all users can't see edit button till save/commit record.
Also to leave message eg. Record is editing by another user, please try later.
I can add one column in table eg. editing number(1), but how to change this column to 1.
when user click on EDIT button?
To give an answer on you question:
You can create a dynamic action which will be triggered on pageLoad. That DA should then update the column to 1 or Y.
!! Warning:
But how will you make sure, that the column will be updated back to 0 or N? Buttons and actions which closes the modal, can update the column back to its initial state, but the X - Close Window button won't. And what if your browser closes or crashes?
In that case, you would be left with a record, which can't be edited anymore by anyone, since that record is still indicated as currently being edited.
I strongly advise not to go down that road!
Instead, trust Oracle APEX's Prevent Lost Updates and Lock Row mechanism's. These are available in the Settings part of the Automatic Row Processing process.

In postman {{url}}:8001/api/{{version}}/auth/login Where can i find the actual value of {{url}} in POSTMAN
If you have {{url}} in your request path and this is red, this means that you do not have a environment or global variable value set.
If you have a value set for this variable name, it will be orange and by hovering over the {{url}} value, you will see the set value displayed in a pop up box.
This can also be viewed in the 'Environment Quick View' by pressing the 'eye' icon, on the right side of the application.
More info on Postman variables can be found here: https://www.getpostman.com/docs/v6/postman/environments_and_globals/variables

I have a combobox that holds a list of different command types. I want to change the visible input fields on my GUI depending on the selected command in the combobox. I am very new to Qt, and I would appreciate it if someone could point me in the right direction to implementing this.
My current idea is to have a "select" button that emits a signal, and the connected slot will grab the current index of the combobox. I THINK I need to implement a custom class to hold a QFrame. The custom class will hold slots that indicate which data inputs (for the selected command) should be displayed in the QFrame.
IE, if COMMAND_1 is selected in the combobox, 3 input fields display in the QFrame. If COMMAND_2 is selected, a pair of radio buttons is displayed in the QFrame, and those 3 input fields are hidden or deallocated.
Is this a good way of attempting to solve this problem?
You're going about it the right way. But Qt actually makes it even easier than what you're thinking.
You can use two built-in widgets: QComboBox and QStackedWidget. You're familiar with the combo box; the stacked widget is a set of widgets, of which only one will be displayed at a time. It's essentially a tabbed widget minus the tabs.
Set up your stacked widget so that its first widget is what you want to show when your combo box is showing its first option, the second for the second, and so on. Then you can connect a built-in signal to a built-in slot: QComboBox::currentIndexChanged(int) to QStackedWidget::setCurrentIndex(int).
Hope that helps!
