I'm looking for some guidance (new to SQL Server in my college work) with unpivot and pivoting data in the following format

...ANSWER
Answered 2021-Sep-27 at 16:04As I mentioned in the comments, what you need here is both an unpivot and a pivot. Rather than using the restrictive UNPIVOT
and PIVOT
operators I use a VALUES
table construct and conditional aggregation:

QUESTION
I am trying to monitor and printout the RAWINPUT from a mouse sent to the foreground window, or just all RAWINPUT
from the mouse in general.
the global hook LowLevelMouseProc
does not work for me because it returns a MOUSEHOOKSTRUCT
that does not give me the dx and dy.
The Raw Input API mentions that for WM_INPUT
received when the current window is in the back ground, wParam will be set to RIM_INPUTSINK
. But I have no idea how to receive WM_INPUT
while the program is in the background.
here is some code explaining what I am trying to do.
...ANSWER

You need to specify the RIDEV_INPUTSINK
flag when registering the device, per the RAWINPUTDEVICE
documentation:
dwFlags
Type:DWORD
Mode flag that specifies how to interpret the information provided by
usUsagePage
andusUsage
. It can be zero (the default) or one of the following values. By default, the operating system sends raw input from devices with the specified top level collection (TLC) to the registered application as long as it has the window focus....
RIDEV_INPUTSINK
0x00000100If set, this enables the caller to receive the input even when the caller is not in the foreground. Note that
hwndTarget
must be specified.
As such, you must specify an HWND
to receive the WM_INPUT
messages, and have a message loop to service that window.
Try this:
QUESTION
I'm trying to use the Python statistics library but have trouble with median
. As you can see below, the program return the mean
, but the list somehow becomes empty for median
and raises error. Please take a look, and thanks in advance!
ANSWER
Answered 2021-Apr-13 at 08:57So the probelm is that usable_lst
is a generator, and once you access it in the mean()
function you empty it.
A fix can be to change usable_lst = map(int, lst)
to usable_lst = list(map(int, last))
You can refer to the following links that might shed more light on the issue you are encountering:
Why can a python generator only be used once?
QUESTION
I am trying to make a program that takes in the Name, Sex, Age and/or Country of a Person
and outputs the correct Name
from the Registry
, when queried with any of the mentioned traits. If such a Person
does not exist, then the output is "Unknown".
For example,
Testcase # 1:
Input:
- Name=Rob Sex=Man Age=42 Country=US
- Name=Robin Sex=Man Age=62 Country=US
- Name=Magda Sex=Woman Age=29 Country=PL
- Name=Peter Sex=Man Age=66 Country=RU
- Name=Pete Sex=Man Age=6 Country=US
- Name=Xiaoling Sex=Woman Age=26 Country=CH
Output:
- Required output criteria: Age=6 Country=US
Therefore, the program should return a Person
of Age=6
and Country=US
, which is "Pete". However, my code is returning "Unknown".
Testcase # 2:
Input:
Name=John Sex=Man Age=46 Country=UK
Name=Anita Sex=Woman Age=22 Country=NL
Name=Keiko Sex=Woman Age=37 Country=JP
Name=Denny Sex=Man Age=13 Country=NL
Name=Mirjam Sex=Woman Age=28 Country=BE
Name=Johnny Sex=Man Age=8 Country=UK
Name=Anna Sex=Woman Age=71 Country=SW
Name=Fred Sex=Man Age=51 Country=NL
Name=Frederique Sex=Woman Age=51 Country=FR
Name=Rob Sex=Man Age=42 Country=US
Name=Robin Sex=Man Age=46 Country=US
Name=Magda Sex=Woman Age=29 Country=PL
Name=Peter Sex=Man Age=66 Country=RU
Name=Pete Sex=Man Age=66 Country=US
Name=Frederique Sex=Woman Age=51 Country=FR
Name=Xiaoling Sex=Woman Age=26 Country=CH
Output:
- Required output criteria: Name=Xiaoling
Therefore, the program should return a Person
of Name=Xiaoling
, which is "Xialong. However, my code is returning "Unknown".

QUESTION
So basically Its automatically generated script from google sheets. I can't find a link or anything which can help me to tweak it so i could upload an image from my website. It sends only the image name instead of an actual image. I would be very glad if someone could explain me how to tweak it so it would send the actual image.
...ANSWER
Answered 2020-Oct-15 at 10:09In Apps Script web apps, in order to send file-input data from the HTML form to the server, the recommended way is to call a server-side function via google.script.run. In this case, you wouldn't rely on a doPost
function (called when POST requests are made to the web app URL), but on a server-side function (named processForm
in the sample below) called via google.script.run
.
When calling a server-side function this way, if you pass the HTML form element as a parameter, you can access the input field names, as explained here:
If you call a server function with a form element as a parameter, the form becomes a single object with field names as keys and field values as values. The values are all converted to strings, except for the contents of file-input fields, which become Blob objects.
Now, you have several options when deciding how to insert the image to the spreadsheet, depending on:
- Whether you want to insert the image to a specific cell or insert the image over cells (not bounded to a specific cell).
- The size of the image.
- Whether you are concerned about making this image publicly accessible.
In case you want to insert the image "over cells" (that is, the image is not located in one specific cell), and in case you don't want this image to be publicly accessible, you can just provide the Blob corresponding to the image as a parameter for Sheet.insertImage(blobSource, column, row).
The corresponding code could be something like this:

QUESTION
I'm able to get my sprite to jump using a Axis.RawInput. This input also serves as a parameter to trigger the jumping animation when the RawInput is greater than 0. This issue with this is when you release the key, the sprite instantly falls back down. How can I perform a fixed jump when the key is pressed once or held down and then have the sprite fall at a fixed rate while also having the animations trigger?
This is what I have in my PlayerMover script now.
