QUESTION
I built an app that runs on Xbox and PCs. I successfully added WebAccountManager and AccountSettingsPane to the app following these instructions: https://docs.microsoft.com/en-us/windows/uwp/security/web-account-manager. It works great on my Surface. However, after testing on Xbox, the AccountSettingsPane does not pop up. Does anyone know if Xbox doesn't support this UWP API?
Here is my code for opening the AccountSettingsPane. It works on PCs and tablets, but not Xbox.
Any ideas?

How to write a function that will return the number of elements in any 1D array regardless of its data type ?
So far I have devised the following function:
...ANSWER
Answered 2020-Dec-23 at 22:21As noted in the comments, user-defined types must be defined in an Object Module to be passed as a variant to a function. It's a misleading phrase because an Object Module is actually a Class Module.
However, it is possible to read the element count of an array of UDTs defined in a Module (or any array for that matter). You would achieve this by reading the SAFEARRAY structure (https://docs.microsoft.com/en-us/windows/win32/api/oaidl/ns-oaidl-safearray) which you access from the array pointer rather than the array itself.
So you could pass the array pointer into your function and thereby avoid the problem of trying to coerce the array to a variant. If, as you say in your question, you are certain the array is only 1 dimension, then coding is relatively straightforward. Arrays of more than one dimension could be used but you'd need a little bit of pointer arithmetic (still pretty trivial, though) to get to the dimension you're after. Note that the code below assumes 64-bit:

I have a file containing words and another "dictionary" file containing definitions. I want to find the definition for each word in the dictionary and write it out to a file.
I looked here and saw an answer that uses Unix/Linux commands but I am on windows and decided to solve in python instead and have come up with a working solution but am wondering if there is a better approach.

...ANSWER
Answered 2018-Oct-03 at 17:07In a rendering, each mesh of the scene usually is transformed by the model matrix, the view matrix and the projection matrix.
The model matrix defines the location, orientation and the relative size of an mesh in the scene. The model matrix transforms the vertex positions from of the mesh to the world space.
The view matrix describes the direction and position from which the scene is looked at. The view matrix transforms from the world space to the view (eye) space.
Note, The model view matrix modelViewMatrix is the combination of the view matrix and the model matrix. But in your case, the model matrix is possibly the identity matrix, and the modelViewMatrix is possibly equal to the view matrix. I assume that, because you don't do the model transformations by a model matrix, but by the vectors orientation and offset.
The light can either be calculated in view space or in world space.
If the light is calculated in view space the light positions and light directions have to be transformed from world space to view space. Commonly this is done on the CPU (before every frame) and the light parameters uniforms are set up with view space coordinates. Since the view position is (0, 0, 0) in view space, is the view vector the the normalized and inverse vertex position (in view space).
If the light calculations are done in world space, then the view vector has to be calculated by the difference of the view position (eye position) and the vertex position (of course in world space).
You can do the light calculations in view space, because the light direction and position is set up in view space (see three.js - Light). You have to transform the normal vector to world space first and then you have to convert from world space to view space. This has to be done similar as you do it for the vertex position. Add the normal vector to the vertex position. Transform this position to world space. The normal vector in world space, is the difference of the calculated position and the vertex position in world space.

QUESTION
This is the third and final remaining problem to a massive data cleaning task I have been working on for over a year. Thank you Stack Overflow community for helping figure out:
Problem 1- Index multiple columns and Match distinct values....
Problem 2- Count unique values that match ID, optimized for 100,000+ cases.
I'm not 100% sure if the following is achievable in excel, but I'll do my best to describe the data cleaning and organization challenge I'm faced with.
I have a series of data markers/attributes that are in a random order across 24 columns, spanning 500,000+ rows. Image 1 below is an example of what the data looks like in raw form, presented across 12 columns and spanning 22 rows for illustrative simplicity. Columns A through L contain the raw data and Columns M through X represent the desired output.
SUMMARY OF THE TASK: What needs to be accomplished is a series of matching functions that search through all indexed columns (in this case columns A through L) to identify unique values (e.g. 1), search for the value in range (in this case A2:L21 range), identify the adjacent values to the unique value (for value 1, adjacent values are 2 and 13-XR), then output them in a descending sequence from most frequently occurring value to least frequently occurring in each row that contains any of the values in question (in this case, 1 occurs 5 times and is placed in M2 through M6; 2 occurs 3 times and is placed in N2 through N6; and 13-XR occurs 2 times and is placed in O2 through O6).
To clarify, below is a step by step description using colours to illustrate the pattern matching in the raw data (columns A through L) and how these patterns should then presented in the output (columns M through X). I've sectioned off each of the following images into the six patterns that are in the raw data.
The above image is the first pattern that would be identified by the VBA solution. It would identify "1" as a unique value and search through the A:L range for number of instances of "1" (highlighted in blue), then identify all the values that can be found adjacent in the same row: "2" in rows 3, 5, and 6 (highlighted in green); and "13-XR" in rows 4 and 5 (highlighted in pink). This would then need to be done for "2", identifying the adjacent values ("1" and "13-XR"), and then for "13-XR", identifying ("1" and "2" as adjacent values). The output would return the unique values with the most frequently occurring in Column M ("1" occurs 5 times), then the second most occurring in Column N ("2" occurs 3 times), and the third most occurring in Column O ("13-XR" occurs 2 times).
The above is little more complex. The VBA would identify "3" as a unique value, search through the A:L range for other instances of "3" and identify all the values that are adjacent to it (in this case, "4", "7", and "9"). It would then do the same for "4", identifying all adjacent values (only "3"); then for "7", identifying adjacent values ("9", "3", and "12"); then for "9" identifying ("7", and "3"); and finally, for "12" identifying adjacent values (only "7"). Then for each row where any of these values are present, the output would return a "3" in column M (occurring three times) and a "7" in column N (also occurring three times); if counts are equal, they could be presented in ascending fashion A to Z or smallest to largest... or just random, the ordering of equal counts is arbitrary for my purposes. "9" would be returned in column O as it occurs two times, then "4" in column P and "12" in column Q, as they both occur once but 12 is greater than 4.
The above image represents what is likely to be a common occurrence, where there is only one unique value. Here, "5" is not identified in any other columns in the range. It is thus returned as "5" in column M for each row where a "5" is present.
This will be another of the more common occurrences, where one value may be present in one row and two values present in another row. In this instance "6" is only identified once in the range and "8" is the only adjacent value found. When "8" is searched for it only returns one instance of an adjacent value "6". Here, "8" occurs twice and "6" only once, thus resulting in "8" imputed in column M and "6" imputed in column N wherever an "8" or a "6" are present in the row.
Here "10", "111", "112", "543", "433", "444", and "42-FG" are identified as unique values associated with one another in the A:L range. All values except "10" occur twice, which are returned in columns M through S in descending order.
This final pattern is identified in the same manner as above, just with more unique values (n=10).
FINAL NOTES: I have no idea how to accomplish this within excel, but I'm hoping someone else has the knowledge to move this problem forward. Here are some additional notes about the data that might help towards a resolution:
- The first column will always be sorted in ascending order. I can do additional custom sorts if it simplifies things.
- Out of the ~500,000 rows, 15% only have one attribute value (one value in column A), 30% have two attribute values (1 value in col A & 1 value in col B), 13% have three attribute values (1 value in col A, B, & C).
- I have presented small numbers in this example. The actual raw data values in each cell will be closer to 20 characters in length.
- A solution that does everything except present the patterns in descending order would be absolutely cool. The sorting would be great but I can live without it if it causes too much trouble.
If anything in this description needs further clarification, or if I can provide additional information, please let me know and I'll adjust as needed.
Thanks in advance to anyone who can help solve this final challenge of mine.
ADDENDUM:
There was a memory error happening with the full data set. @ambie figured out the source of the error was adjacent chains (results) numbering in the 1000s (trying to return results across 1000s of columns). Seems the problem is not with the solution or the data, just hitting a limitation within excel. A possible solution to this is (see image below) to add two new columns (ATT_COUNT as column M; ATT_ALL as column Z). ATT_COUNT in Column M would return the total number of unique values that would ordinarily be returned across columns. Only up to the top 12 most frequently occurring values would be returned in columns N through Y (ATT_1_CL through ATT_12_CL). To get around the instances where ATT_COUNT is > 12 (& upwards of 1000+), we can return all the unique values in space delimited format in ATT_ALL (column Z). For example, in the image below, rows 17, 18, 19, and 21, have 17 unique values in the chain. Only the first 12 most frequently occurring values are presented in columns N through Y. All 17 values are presented in space delimited format in column Z.

Answered 2017-Aug-08 at 17:13We don't normally provide a 'code for you service' but I know in previous questions you have provided some sample code that you've tried, and I can see how you wouldn't know where to start with this.
For your future coding work, the trick is to break the problem down into individual tasks. For your problem, these would be:
- Identify all the unique values and acquire a list of all the adjacent values - fairly simple.
- Create a list of 'chains' which link one adjacent value to the next - this is more awkward because, although the list appears sorted, the adjacent values are not, so a value relatively low down in the list might be adjacent to a higher value that is already part of a chain (the 3 in your sample is an example of this). So the simplest thing would be to assign the chains only after all the unique values have been read.
- Map of each unique value to its appropriate 'chain' - I've done this by creating an index for the chains and assigning the relevant one to the unique value.
Collection objects are ideal for you because they deal with the issue of duplicates, allow you to populate lists of an unknown size and make value mapping easy with their Key property. To make the coding easy to read, I've created a class containing some fields. So first of all, insert a Class Module and call it cItem. The code behind this class would be:
