By slice I think you mean Array.

Regardless of whether you include the section or not, the

First you map to get the array of value from col2-5 for each object, then reduce it to find the max for the corresponding column

Converting to a Date via the Date() constructor is notoriously tricky. Thankfully, since D3 gives us methods to go from a date to a string, it also has the reverse, going from a string to a date.

Our process will be twofold:

1. For each string in a certain format, convert to Date with d3.timeParse().
2. Convert each date to your desired string format.

So your problem is a miss match between lts and extra-deps versions. As @arrowd commented, the solution is to remove extra-deps section... Let me explain the reason in detail:

• Each lts (a.k.a snapshot) has an associated ghc version. For lts-16.3 such a version is ghc-8.8.3 as you can check in the linked docs.

• when you write a dependency in package.yaml, stack will use the version defined in the selected lts, and it'll be downloaded form stackage server. For example, in the linked docs, you can search for aeson package. The version used in lts-16.3 is aeson-1.4.7.1

• All packages version in a lts are guaranteed to work well together without dependency problems. (I think there are a few exceptions documented in the stack web, due to system packages but I'm not so sure)

• The problem comes with extra-deps. Which are downloaded directly from hackage server with no guarantees of dependency compatibility. In your case, one extra dep was ghc-8.6.5. Obviously, there is a dependency problem between the compiler version defined in the snapshot: ghc-8.8.3 and the version you want as an extra-dep ghc-8.6.5

Hope it clarifies some stack terminology.

A 500 error indicates that a request was made to a web server and it could not handle it. It will be tricky to find the root cause, as the issue could be front-end, back-end, environment (web.config / app pool settings) or an issue with DevExpress.

Therefore you should run the code in isolate. For example: create a blank aspx page (no Master Page), which contains the AjaxFileUpload and has empty function/methods. If this works, then add the bare minimum code to save an image (to a temp folder). If this works, then copy code across bit-by-bit until you can create the error.

Alternatively add some logging to your back-end code. It looks like you have a try/catch that hides exceptions. If there's an error then the variables results is returned as null. It look like MultiUploadComplete() doesn't checks for success, but merely the size of the file?

Alternatively re-write the AjaxFileUpload. It's not well supported and modern JavaScript, HTML and web browsers means that it's a lot easier to implement.

Take a look at https://www.smashingmagazine.com/2018/01/drag-drop-file-uploader-vanilla-js/. This article shows how to create a mutli-file drag & drop uploader using pure JavaScript, HTML5. You'll need to create an end point, preferably using a WebApi or generic handler (if using an older version of asp.net)

As a simple proof of concept. I've put together an aspx page, which post images to an api. It sends the files individually at once for performance (but you can do it all as one request). The main thing to point out is that theres no third part libraries and you have flexibility to change the look and feel of you file uploader.

ASPX code

I actually managed to figure out what was going on! I am still fairly positive that this is not at all an optimal solution, but it now does exactly what it's supposed to -- walk all valid paths and then return an array containing the longest path it walked. Here's the final code:

I can see how this would be difficult, the format is quite hard to deal with because the title isn't the parent of the section but I found a way around.

EDIT: now pulls all rows not just first

You must not modify your hexValueList list while painting.

A program does not decide when a component’s paint method is called. The system is in control of that.

Your paint method can be called for many different reasons, all beyond your control. Some possible reasons are:

• User moves the window
• User iconifies or deiconifies the window
• User moves another window in front of your window
• User brings your window to the front
• User moves the mouse over your component
• User locks or blanks the screen
• User scrolls the web page containing the applet
• User reloads the web page containing the applet

It is possible for painting to occur many times per second. Or, it may occur only occasionally.

Since you have no control over the timing of calls to your paint method, you must only have drawing logic in it. If you remove values from a List, those values won’t be available during subsequent calls to the paint method.

This is why you must not modify your hexValueList list in the placeNumbers method, since that method is called by drawHexagonalGrid which is called by paint.

Instead of removing numbers from hexValueList, iterate through it, using that List’s iterator() method, and pass each iterated int value as a parameter to placeNumbers:
