QUESTION
I wanted to set different background in my document with the following conditions
- The first page of the document should contain the first.png as a background.
- The remaining pages of the document should contain a second.png as a background.
I'm able to set backgrounds as per my expectations if the first page of the input document doesn't contain an image in the header. If the document's first page contains an image in the header it is removing that header on the first page only.
I'm using the following code snippet to achieve my functionality.
...ANSWER
Answered 2021-May-27 at 07:27The problem occurs because your input document contains only the primary header. When you move the DocumentBuilder’s cursor into the first page header, Aspose.Words create new empty first page header. To keep the content of the primary header on the first page you should simply copy the content of the primary header into the newly created first page header. Here is a simple code that does this.

QUESTION
I have a Dictionary
where I save objects to parse to my plugin system, some of these objects need to be a copy not the original so I use this DeepClone method:
ANSWER
Answered 2021-May-10 at 20:56Your DeepCloneMemoryStream
recreates the exact type via Reflection, even if T
is object.
Your DeepCloneJSON
roundtrip via JSON string loses type information, and so deserialization requires the exact type to be specified. In your case, you are only passing object
as T
and therefore you get back a JsonElement
instead of a List
.
The following will work if you change how you make your call:
QUESTION
I was recently looking over this question on deep cloning in C#: How do you do a deep copy of an object in .NET?
I'm not a C#/.NET expert, so if this is completely off, someone please correct me. Why aren't people suggesting doing the following?

I have an object that is a combination of literals and accessors:
...ANSWER
Answered 2021-Jan-04 at 18:03You can do a deep clone with using destructuring assignment. afaik, there are no downsides but could be wrong. in my testing it works for your example. it should be noted that this is not a complete deep cloning solution, as it won't handle Date
or Map
cloning without additional code to handle those types.
QUESTION
I have a modal containing a button that fires a HTTP request, at which point the displayed html will change depending on a successful/error response from the server, where the response changes a state prop that is dealt with in the mapStatesToProps
function.
The issue I have now is that I am wanting to reset the modal to its initial state pre-request when I close it. I had previously done this by using local component state but have since updated the functionality to use the request mapped state props shown above.
I am curious if it possible to reset the state without firing a dispatch to a random URI?

QUESTION
To set this up I create 2 fleet objects, store them in an array, then print the array to console. This is what I get after both fleet objects are created.
...ANSWER
Answered 2020-Oct-12 at 22:36Your issue is inside your getFleet()
function. Instead of checking each object number for equality, you're actually overwriting the variable. The fix is as simple as changing one equal sign to three.

Answered 2020-Sep-17 at 13:28I think the reason is that your CalendarEntry
class does not have a default constructor, which is needed as Jackson will try to deserialize it.

I'm trying to change the Vuex state by splicing the state.todos array, changing the one Object in array with another One that is given in my component / through the mutations
this is my Vuex state

methods accept only one argument. You can use an object with multiple properties as an argument and then de-structure it in the Vuex store.

QUESTION
I am trying to implement a table in react where the user can edit individual rows by clicking the edit button on a row and then submit once he has made his change. I have say two components App.js and its child Table.js to implement this.
The way I thought of doing this initially was letting each of this component have their own state for rows and then the Table component reads from the props send to it by parent initially and only change the parent rows when users submits the change as oppose to onChange event. But I've read that reading props into state is an anti-pattern.
So decided to have everything in the parent by having two values for row (oldrows,newrows). And using them to maintain state instead, This is the design I came up with :
But what happens is whenever I click cancel the oldRows get bound to the newRows, here is a codePen example I put up:
...ANSWER
Answered 2019-Oct-03 at 02:24I didn't find any issue after the cancel function. For me, the issue was coming up after I called the save function.
After clicking on the save button and then editing again, the old values and new values were get bound.
The handleSubmitRowInput
function should create a new array for the oldValuesArray using the cloneDeep
function
